Nitrous oxide (N 2 O) is a potent greenhouse gas that contributes significantly to the healthcare sector's carbon footprint. Pre-utilisation losses of N 2 O are up to 95%. Decommissioning manifolds can reduce these losses. Hospitals in our Greater London research network with at least one active N 2 O manifold were included in the Nitrous Oxide Manifold and Other Reduction of Emissions (NoMoreGas) study. N 2 O utilisation data were collected continuously over 5 days and extrapolated over a year, in addition to collecting procurement records from the preceding financial year. The primary outcome was the discrepancy between clinically utilised N 2 O and the quantity procured by hospitals, referred to as the 'N 2 O gap'. Secondary outcomes included anaesthetists' self-reported utilisation of N 2 O and their opinions on manifold decommissioning. Eighteen of 53 hospitals were included. In total, 6 487 200 L of N 2 O were procured with a median (IQR) of 304 200 (183 600–473 400) L per site. During the 5-day data collection period, sites utilised a median (IQR) of 501 (42–1409) L of N 2 O. Extrapolating over a year resulted in a median (IQR) annual utilisation of 36 573 (3066–102 857) L per site and a total of 1 175 348 L. This represented an estimated 18% of the N 2 O procured, suggesting pre-utilisation losses of 5 311 852 L. Among surveyed anaesthetists, 70% (n =309) reported using N 2 O within the previous year, with one-third (n =97) using it once a week or more. There was widespread support for decommissioning manifolds. Consistent with other reports, the data demonstrate a substantial discrepancy between the quantities of N 2 O procured and utilised clinically, indicative of significant pre-utilisation losses. Our findings support the decommissioning of N 2 O manifolds for environmental and economic benefits. [ABSTRACT FROM AUTHOR]

Background: Day surgery has developed rapidly in China in recent years, although it still faces a shortage of anesthesiologists to handle pre-anesthesia routine before surgery. We hypothesized that ChatGPT may assist anesthesia practitioners in preoperative assessment and answer questions on the concerns of patients. The aims of this study were to examine the ability of ChatGPT to assess preoperative risk and determine its accuracy in answering questions regarding knowledge and management of day surgery anesthesia. Methods: One-hundred fifty patient profiles were generated to simulate day surgery patient presentations that involved complications of varying acuity and severity. The ChatGPT group and the expert group were both required to evaluate the profiles of 150 simulated patients to determine their ASA-PS classification and whether day surgery was recommended. ChatGPT was then asked to answer 131 questions about day surgery anesthesia that represented the most common issues encountered in clinical practice. The performance of ChatGPT was assessed and graded independently by two experienced anesthesiologists. Results: A total of 150 patient profiles were included in the study (75 males [50.0%] and 75 females [50.0%]). There was no difference between the ChatGPT group and the expert group for the ASA-PS classification and assessment of anesthesia risk in the patient profiles (P > 0.05). Regarding recommendation for day surgery in patients with certain comorbidities (ASA ≥ II), the expert group was inclined to require further examination or treatment. In addition, the proportion of conclusions made by ChatGPT was smaller than that of the experts (i.e., ChatGPT n (%) vs. expert n (%): day surgery can be performed, 67 (47.9) vs. 31 (25.4); needs further treatment and evaluation, 56 (37.3) vs. 66 (44.0); and day surgery is not recommended, 18 (12.9) vs. 29 (9.3), P < 0.05). We showed that ChatGPT had extensive knowledge related to day surgery anesthesia (94.0% correct), with most of the points (70%) considered comprehensive. The performance of ChatGPT was also better in the domains of peri-anesthesia concerns, lifestyle, and emotional support. Conclusions: ChatGPT can assist anesthesia practitioners and surgeons by alerting them to the ASA-PS classification and assessing perioperative risk in day surgery patients. ChatGPT can also be trusted to answer questions and concerns related to pre-anesthesia and therefore has the potential to provide important assistance in clinical work. [ABSTRACT FROM AUTHOR]

ABSTRACT Background Materials and Methods Results Conclusions Traumatic dental injuries with tracheal intubation during general anesthesia are considered one of the most common complications. It is also the primary reason for malpractice legal claims against anesthesiologists according to insurance companies. There is much information regarding the incidence, consequences, and risk factors of traumatic dental injuries during general anesthesia. This study aimed to assess the awareness (knowledge, practice, and attitude) of anesthetists regarding peri‐anesthetic traumatic dental injuries and discuss measures to reduce the risk regarding peri‐anesthetic traumatic dental injuries.Sixty seven anesthetists participated in this cross‐sectional survey between January 2023 and July 2023, which was carried out in the Syrian Arab Republic. The questionnaire was generated using Google Forms and sent individually, as the researcher (MNA) was accompanied by all included anesthesiologists while filling out all the questionnaire paragraphs to answer any questions. The Fisher exact test and Pearson's Chi‐squared test were used to analyze the results.The dental trauma caused by the anesthetists during their professional careers was 38.8%, and none of them were exposed to any legal claim. 77.6% of the anesthetists thought that avulsed permanent teeth could be replanted, 46.2% believed that the procedure must be done in < 30 min, and 84.6% thought they could not do it themselves and would send the patient to a dentist after the procedure. More than half of respondents (63.5%) indicated that the sterile saline solution was the best storage medium for avulsed teeth. Furthermore, 74.6% of anesthetists stated that emergency intubations are related to more traumatic dental injuries in comparison with elective intubation and about 62% were aware of the importance of mouthguard. However, nearly 57% complained about the shortage of knowledge related to the oral cavity and its special structure.Syrian anesthetists have limited awareness (knowledge, practice, and attitude) of traumatic dental injury classification, prevention, and management. More information and training are still needed about factors used within clinical dentistry. [ABSTRACT FROM AUTHOR]

Aim: Anastomotic stricture occurs in up to 30% of colorectal resections; however, evidence on risk factors and preventive measures remains scarce. This study aimed to identify technical factors responsible for increasing the risk for colorectal and coloanal anastomotic strictures. Method: This was a retrospective cohort study of patients with anastomotic stricture who underwent resection and/or redo anastomosis between January 1, 2011 and August 1, 2021 in a tertiary referral centre. Patients with anastomotic stricture were compared with an equal number of randomly selected patients without anastomotic complications, who were operated on during the same time period. The main outcome measures were technical risk factors of anastomotic stricture. Results: Each group included 50 patients who were similar for age, sex, American Society of Anesthesiologists score, distance of anastomosis to the dentate line and indication for surgery. Median follow‐up was significantly longer in the non‐stricture group (38.6 months vs. 12.6 months, p = 0.04). Splenic flexure mobilization [hazard ratio (HR) = 0.18 [2], 95% CI: 0.08–0.39, p < 0.001], high ligation of the inferior mesenteric artery (HR = 0.22, 95% CI: 0.09–0.5, p < 0.001) and high ligation of the inferior mesenteric vein (HR = 0.21, 95% CI: 0.09–0.50, p < 0.001) were associated with a lower likelihood of anastomotic stricture. Conversely, use of a 25‐mm‐diameter circular stapler (HR = 22.69, 95% CI: 2.69‐191.10, p < 0.001), clinically significant anastomotic leak (HR = 3.94, 95% CI: 2.04–7.64, p < 0.001), firing the stapler more than once for rectal division (HR = 24.75, 95% CI: 6.85–89.38, p < 0.001) and diverting stoma (HR = 3.087, 95% CI: 1.736–5.491, p < 0.0001) were predictive of an anastomotic stricture. Conclusion: Failure to mobilize the splenic flexure and to perform high ligation of the inferior mesenteric vessels were associated with higher odds of anastomotic stricture. A small‐diameter circular stapler and multiple distal stapler firings were also associated with anastomotic stricture. These data support routine splenic flexure ligation and high ligation of the inferior mesenteric vessels as well as avoidance of both multiple stapler firings for rectal transection and a 25‐mm circular stapler for anastomosis.

Background: Multiple preoperative calculators are available online to predict preoperative mortality risk for noncardiac surgical patients. However, it is currently unknown how these risk calculators perform across different raters. The current study investigated the interrater reliability of three preoperative mortality risk calculators in an elective high-risk noncardiac surgical patient population to evaluate if these calculators can be safely used for identification of high-risk noncardiac surgical patients for a preoperative multidisciplinary team discussion. Methods: Five anesthesiologists assessed the preoperative mortality risk of 34 high-risk patients using the preoperative score to calculate postoperative mortality risks (POSPOM), the American College of Surgeons surgical risk calculator (SRC), and the surgical outcome risk tool (SORT). In total, 170 calculations per calculator were gathered. Results: Interrater reliability was poor for SORT (ICC (C.I. 95%) = 0.46 (0.30–0.63)) and moderate for SRC (ICC = 0.65 (0.51–0.78)) and POSPOM (ICC = 0.63 (0.49–0.77). The absolute range of calculated mortality risk was 0.2–72% for POSPOM, 0–36% for SRC, and 0.4–17% for SORT. The coefficient of variation increased in higher risk classes for POSPOM and SORT. The extended Bland–Altman limits of agreement suggested that all raters contributed to the variation in calculated risks. Conclusion: The current results indicate that the preoperative risk calculators POSPOM, SRC, and SORT exhibit poor to moderate interrater reliability. These calculators are not sufficiently accurate for clinical identification and preoperative counseling of high-risk surgical patients. Clinicians should be trained in using mortality risk calculators. Also, clinicians should be cautious when using predicted mortality estimates from these calculators to identify high-risk noncardiac surgical patients for elective surgery. Highlights: -Interrater reliability for POSPOM, SRC and SORT preoperative mortality risk predictors is lower than expected. -Clinicians need to use preoperative mortality risk calculators with caution when using them for identification and preoperative counseling of high-risk noncardiac surgical patients. -In this study all raters using POSPOM, SRC and SORT for preoperative mortality risk calculation, contributed to variability in risk estimates.

Background: According to the Chinese Society of Anesthesiology, it is recommended that patients with difficult airways be documented and notified, which will provide healthcare professionals with a direct reference when managing airways. However, compliance with this initiative remains unclear. This study was conducted to investigate the current status and need for difficult airway notification at Plastic Surgery Hospital and to explore the factors contributing to noncompliance. Methods: Anesthesiologists, surgeons, and patients in Plastic Surgery Hospital were administered separate questionnaires regarding notification of difficult airway management. Participants were surveyed regarding their attitudes and current practices regarding difficult airway notification. In addition, questions were asked regarding the barriers that contribute to noncompliance. Results: A total of 632 valid responses were obtained and analyzed, giving a response rate of 99.21%. 399 patients (89.46%) felt it was very important for anesthesiologists to inform them about their difficult airway, and 91.03% felt it was very important for them to receive a letter of their airway assessment. However, twenty-two anesthesiologists (64.7%) reported verbally informing less than 50% of patients about their difficult airway after surgery, and only four anesthesiologists informed all patients they encountered. Most surgeons (91.22%) and anesthesiologists (91.18%) believe that it is vital to inform patients verbally, while 114 surgeons (77.03%) and 31 anesthesiologists (91.18%) believe that it is essential to complete a difficult airway notification alert. Among the factors causing noncompliance, 17 (34.69%) believed that absence of mandatory rules, 9 (18.37%) believed that increased workload, and 8 (16.33%) believed that notification methods were lacking. Conclusions: The compliance to difficult airway notification remains low in Plastic Surgery Hospital despite the high incidence of difficult airways. Although anesthesiologists, surgeons, and patients are strongly in favor of it. Among the barriers to compliance were the absence of a well-developed notification system and a means of notification such as an alert form for difficult airways. This may spur the anesthesiology society to publish the notification system. [ABSTRACT FROM AUTHOR]

Background: Burnout syndrome is marked by three primary domains: emotional exhaustion, depersonalization, and low personal accomplishment. This study assessed the prevalence of burnout syndrome among anesthesiologists, anesthesia technicians, and intensive care unit (ICU) nurses in Palestinian hospitals. In addition, this study also sought to assess associations and identify the factors that can predict higher burnout among anesthesiologists, anesthesia technicians, and ICU nurses. Methods: This study was conducted in a cross-sectional design using a questionnaire between October 2023 and December 2023. The questionnaire collected the demographic variables of the healthcare providers, their living conditions, lifestyle, working conditions, job satisfaction, and intention to change the profession. The healthcare providers were included from 12 different hospitals. Burnout syndrome was assessed using the Maslach Burnout Inventory-Human Services Survey for Medical Personnel (MBI-HSS-MP). Results: A total of 250 healthcare providers were invited to participate in this study, of those, 212 completed the questionnaire, giving a response rate of 84.8%. Of the healthcare providers, 72 (34.0%) were anesthesiologists, 41 (19.3%) were anesthesia technicians, and 99 (46.7%) were ICU nurses. Of all healthcare providers, 151 (71.2%) reported emotional exhaustion, 125 (59%) reported depersonalization and 145 (68.4%) reported a lack of personal achievement based on the MBI-HSS-MP criteria for burnout. Multiple linear regression showed that higher emotional exhaustion scores could be predicted by the number of working hours per day (p-value = 0.039) and higher depersonalization scores could be predicted by having children (p-value = 0.001). On the other hand, lower personal achievement scores could be predicted by having children (p-value = 0.006), not owning a car (p-value = 0.036), and having more night shifts (p-value = 0.049). Conclusions: The findings of this study indicated that burnout syndrome was prevalent among anesthesiologists, anesthesia technicians, and ICU nurses in Palestinian hospitals. Healthcare authorities and professional bodies should consider designing interventions to reduce burnout and improve the psychological well-being of anesthesiologists, anesthesia technicians, and ICU nurses. Further studies are required to identify the most effective interventions for reducing burnout among anesthesiologists, anesthesia technicians, and ICU nurses in Palestine. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to evaluate the current practices and trends of intraoperative facial nerve (FN) monitoring (IOFNM) during parotidectomy. Methods: A questionnaire containing 33 questions collecting information on the usage, indications, settings, techniques, loss of signal (LOS) management, anesthesiologist cooperation, and perception of usefulness of IOFNM was distributed among 348 members of the Korean Society of Head and Neck Surgery (KSHNS) via a dedicated website. Results: The response rate was approximately 25.6%, and 97% of the respondents reported using IOFNM selectively or routinely during parotidectomy. IOFNM usage decreased as the surgeon's level of experience increased (p = 0.089), from 100% in those with less than 5 years of experience to 75% in those with 20 or more years. Approximately 95% of respondents reported that the initial event threshold for electromyography activity used was 50–149 μV. Moreover, 52.4% of respondents performed neural mapping of the FN before visual identification. Initial management of LOS in visually intact FNs included checking the IOFNM system (75.3%), confirmation of muscle relaxant dosage (75.3%), and facial twitch identification (58.8%). Further management included proceeding with surgery regardless of persistent LOS (81.2%) and steroid administration sometimes or all of the time (72.9%). Overall, 98.8% of respondents found IOFNM beneficial for safe execution of parotidectomy. Conclusions: The majority of KSHNS surgeons used IOFNM during parotidectomy, although the clinical implementation of the procedure and LOS management varied between practitioners. This could be attributed to the lack of standardized protocols for IOFNM, emphasizing the need for the development of evidence-based consensus guidelines for all institutions. [ABSTRACT FROM AUTHOR]

Background: A rare case report of lysyl hydroxylases deficiency undergoing scoliosis surgery. Case presentation: An 8-year-old Persian patient with a known case of lysyl hydroxylases deficiency presented with scoliosis. On physical examination, he had course facial hair, elbow flexion contracture, and knee flexion contracture. He had a history of eye surgery, clubfoot, and hearing problems. He underwent scoliosis surgery with growing rod instrumentation. Conclusion: Surgery can be done in these patients with caution, and the surgeon and anesthesiologist should be aware of potential complications during and after surgery. [ABSTRACT FROM AUTHOR]

Background: Working long consecutive hours' is common for anaesthesia and critical care physicians. It is associated with impaired medical reasoning's performance of anaesthesiology and serious medical errors. However, no study has yet investigated the impact of working long consecutive hours' on medical reasoning. Objective: The present study evaluated the impact of working long consecutive hours' on the medical reasoning's performance of anaesthesiology and intensive care physicians (residents and seniors). Methods: This multicentric, prospective, cross-over study was conducted in 5 public hospitals of Normandy region. Two groups of anaesthesia and critical care physicians were formed. One was in a rest group, RG (after a 48-hours weekend without hospital work) and the other in Sleep Deprivation Group (SDG) after a 24 h-consecutives-shift. Changes in medical reasoning's performance were measured by 69-items script concordance tests (SCT) through to the two tests. Group A completed the first part of the assessment (Set A) after a weekend without work and the second part (Set B) after a 24 h-shift; group B did the same in reverse order. The primary outcome was medical reasoning's performance as measured by SCT in RG and SDG. The secondary outcomes included association between the performance with the demographic data, variation of the KSS (Karolinska sleepiness scale) daytime alertness score, the number of 24 h-shift during the previous 30 days, the vacations during the previous 30 days, the presence of more or less than 4 h consecutives hours slept, the management of a stressful event during the shift, the different resident years, the place where the shift took place (University hospital or general hospitals) and the type of shift (anaesthesia or intensive care). Results: 84 physicians (26 physicians and 58 residents) were included. RG exhibited significantly higher performance scores than SDG (68 ± 8 vs. 65 ± 9, respectively; p = 0.008). We found a negative correlation between the number of 24 h-shifts performed during the previous month and the variation of medical reasoning's performance and no significant variation between professionals who slept 4 h or less and those who slept more than 4 h consecutively during the shift (-4 ± 11 vs. -2 ± 11; p = 0.42). Conclusion: Our study suggests that medical reasoning' performance of anaesthesiologists, measured by the SCT, is reduced after 24 h-shift than after rest period. Working long consecutive hours' and many shifts should be avoided to prevent the occurrence of medical errors. [ABSTRACT FROM AUTHOR]

Pediatric patients who undergo spinal corrective surgery often require multiple blood product transfusions. The use of antifibrinolytics, especially tranexamic acid (TXA), to mitigate intraoperative blood loss has increased in popularity. The goal of this quality improvement project was to evaluate provider compliance with a TXA dosing protocol during pediatric corrective spine procedures. A retrospective chart review was conducted to compare pre- and postimplementation data on cell saver and packed red blood cell (PRBC) administration and dose of antifibrinolytic administered. A total of 486 patients (68% idiopathic and 32% neuromuscular) were evaluated over a 9-year period. Following implementation of the protocol, patients of idiopathic origin experienced a 20% reduction in cell saver administration, a 10% reduction in PRBC administration, and a 37% increase in provider compliance with the dosing protocol. Patients of neuromuscular origin experienced a 53% increase in provider compliance with the recommended TXA dosing protocol; however, this patient population did not experience a statistically significant reduction in transfusion requirements. Implementation of an antifibrinolytic protocol can facilitate compliance with recommended TXA dosing parameters and potentially decrease intraoperative blood loss, reducing blood product transfusion requirements.

This project sought to educate providers on the benefits of lung protective ventilation (LPV), implement a LPV protocol in robotic surgery, and evaluate adherence to the protocol in the adult (≥ 18 years) robotic-assisted surgery population. This project used a pre/post quality improvement design with a retrospective chart review and periodic knowledge, attitude, and practice surveys over the course of 6 months. This project retrospectively reviewed electronic medical records to assess adherence to the LPV protocol. The type of surgery; ventilator settings including positive end-expiratory pressure, FiO2, tidal volume, SpO2, ventilator mode, compliance, driving pressure and peak pressure; patient height and weight; patient body mass index; and American Society of Anesthesiologists physical status classification were collected. Analyzed results compared baseline preeducation data and data collected at 3- and 6-months postimplementation. Adherence to the LPV protocol parameters of tidal volume (P < .001), respiratory rate (P = .014), and driving pressure (P < .001) within LPV limits improved with statistical significance from pre- to postimplementation. Provider confidence and knowledge increased from pre- to posteducation (P = .049). Adherence to a LPV protocol improved with education and information tools. [ABSTRACT FROM AUTHOR]

BACKGROUND: In recent years, there has been growing interest in laparoscopic liver resection (LLR) and the audit of the results of surgical procedures. The aim of this study was to define reference values for LLR in segments 7 and 8. STUDY DESIGN: Data on LLR in segments 7 and 8 between January 2000 and December 2020 were collected from 19 expert centers. Reference cases were defined as no previous hepatectomy, American Society of Anesthesiologists score less than 3, BMI less than 35 kg/m2, no chronic kidney disease, no cirrhosis and portal hypertension, no COPD (forced expiratory volume 1 <80%), and no cardiac disease. Reference values were obtained from the 75th percentile of the medians of all reference centers. RESULTS: Of 585 patients, 461 (78.8%) met the reference criteria. The overall complication rate was 27.5% (6% were Clavien-Dindo 3a or more) with a mean Comprehensive Complication Index of 7.5 ± 16.5. At 90-day follow-up, the reference values for overall complication were 31%, Clavien-Dindo 3a or more was 7.4%, conversion was 4.4%, hospital stay was less than 6 days, and readmission rate was <8.33%. Patients from Eastern centers categorized as low risk had a lower rate of overall complication (20.9% vs 31.2%, p = 0.01) with similar Clavien-Dindo 3a or more (5.5% and 4.8%, p = 0.83) compared with patients from Western centers, respectively. CONCLUSIONS: This study shows the need to establish standards for the postoperative outcomes in LLR based on the complexity of the resection and the location of the lesions. [ABSTRACT FROM AUTHOR]

Sugammadex, the first noncompetitive antagonist developed for the reversal of neuromuscular blockade (NMB), is one of the few drugs that has revolutionized anesthetic practice. However, sugammadex use was only recently approved for children aged 2 to 17 years, and it remains unapproved for children under 2. Although the precision and reliability of reversal of NMB with sugammadex are of great benefit in pediatric anesthesia, several important questions remain regarding its use in our youngest patients. In this brief narrative review, we aim to provide an overview of the key considerations and potential challenges that anesthesiologists often face when using sugammadex in pediatric patients.

Objective: Regional blocks in open abdominal surgery reduce postoperative opioid use. Use in minimally invasive gynecologic surgery has had inconsistent results regarding postoperative pain and narcotic use. Effects on intraoperative opioid requirements are unknown. This study examined intraoperative and immediate postoperative effects of 2 regional anesthetic techniques. Materials and Methods: Of 394 patients, 79 had transverse abdominis plane (TAP) block, 207 had quadratus lumborum (QL) block, and 108 had no block (NB). Intraoperative opioids were converted to morphine-equivalent doses (MEDs) and divided by surgical minutes to control for operative time. Univariate analysis examined differences in opioid needs and secondary outcomes. Results: Average intraoperative MED/minute per cohort was 0.21 for QL, 0.25 for TAP, and 0.25 for NB (p = 0.002). QL used fewer intraoperative opioids than TAP (p = 0.01) and NB (p < 0.001). There was no difference in intraoperative MED use between TAP and NB (p = 0.47). Subgroup analysis showed increased intraoperative MED in individuals under age 40, and no difference by American Society of Anesthesiologists classification, robotic surgery use, or presence of endometriosis. Postoperative MED use was 17, 23.8, and 24.2 for QL, TAP, and NB respectively (p = 0.001). There was no difference in mean incidence of nausea (p = 0.88) or vomiting (p = 0.29) among groups. Time to postoperative anesthesia unit (PACU) discharge was 108 minutes for QL, 112 minutes for TAP, and 125 minutes for NB (p = 0.007). Conclusions: Preoperative QL blockade is associated with decreased narcotic use and a quicker time to discharge. While statistically significant, this difference of 18 MED and 12-minute quicker discharge has minimal clinical significance and is not cost-effective, given the exponential cost of liposomal bupivacaine, compared to standard bupivicaine.

Introduction: Difficult intubation presents a significant challenge for anaesthesiologists, particularly when it is unexpected. Early recognition of a difficult airway through preoperative assessment is crucial to prevent potential complications associated with airway management failure. This study primarily aims to correlate the Mallampati modified score with the laryngoscopic view to enhance the prediction of difficult airways. Materials and Methods: This study included 80 adult patients, aged 18-75 years, of either sex and classified as ASA Class I and II, all requiring endotracheal intubation. Preoperative airway assessment was performed using the Modified Mallampati test, and the results were correlated with laryngoscopic grading based on the Cormack-Lehane classification. Statistical analysis was conducted using the Chi-square test and Kappa statistics. Results: The study found that 10% of the cases predicted to be easy intubations were actually difficult. Conversely, no difficult intubations were predicted as difficult in advance. Additionally, 10% of the cases that were predicted to be difficult intubations turned out to be easy. Conclusion: The Mallampati classification did not exhibit a grade-to-grade correlation with the Cormack-Lehane grading during direct laryngoscopy, indicating limitations in its predictive accuracy for difficult intubation.

Background: Breastfeeding has numerous health benefits for patients and their infants. There are inconsistencies in how anesthesia providers care for lactating patients undergoing anesthesia. Providers may be cautious and have patients "pump and dump" instead of following current evidence-based recommendations. Video-based education provides a novel reference for health care providers in their fast-paced work environments. This project evaluated the effectiveness of an online video module and resources accessed at the bedside for anesthesia providers caring for lactating patients. Materials and Methods: A preintervention survey was sent to anesthesia providers at a large academic institution to assess baseline knowledge of current recommendations for caring for lactating patients having anesthesia. A quick response code-linked video module and references were created and disseminated to all anesthesia providers. A postsurvey was sent to assess knowledge and satisfaction with the educational approach. Postsurvey data were compared with presurvey data. Results: All who watched the educational video found the education helpful to care for lactating patients undergoing surgery. In the posteducation group, 93% of providers selected the correct recommendation to continue breastfeeding or pumping after general anesthesia or sedation once the patient is awake and alert, compared with 48% in the pre-education group. After education, 92% would recommend preoperative feeding or pumping prior to transport to the operating room, compared with the 50% in the pre-education group. Conclusions: Video-based, just-in-time education is an effective way to deliver updated information to anesthesia providers. This format is conducive to just-in-time delivery, and there may be implications for other patient populations that present infrequently but require population-specific care. [ABSTRACT FROM AUTHOR]

Background: Laryngeal mask airway (LMA) has been increasingly used for airway management; however, LMA insertion can be difficult and cause adverse effects. Therefore, the rapid, safe, and effective insertion of LMA is necessary. This study aimed to compare the efficacy of the standard method with that of the 30° curved tongue depressor-aided technique for LMA insertion to determine the superior technique. Methods: This study included 154 patients aged 18–70 years (American Society of Anesthesiologists class I or II) scheduled for general anesthesia. The patients were randomly assigned to the standard LMA insertion group (Group C, n = 77) or the 30° curved tongue depressor-aided LMA insertion group (Group T, n = 77). The primary outcome evaluated was the first-attempt success rate. The secondary outcomes were the second-attempt success rate, insertion time, fiberoptic position grade, oropharyngeal leak pressure (OPLP), and adverse events. Results: The first-attempt success rate was significantly higher in Group T than in Group C (97.40% vs. 88.31%, P = 0.029). The second-attempt success rate (P = 0.209), insertion time (P = 0.340), fiberoptic position grade (P = 0.872), and OPLP (P = 0.203) were slightly improved in Group T; however, there was no statistical significance. Bleeding events were reduced in Group T than in Group C (6.49% vs. 14.29%); however, there was no statistical significance. The incidence of sore throat symptoms was significantly reduced in Group T than in Group C (5.19% vs. 15.58%, P = 0.035). Conclusions: The curved tongue depressor-aided technique significantly improved the first-attempt success rate of LMA insertion and reduced the incidence of sore throat symptoms.

Target-controlled infusion (TCI) is a mature technology that enables the delivery of intravenous anaesthetics in the concentration domain. The accuracy of the pharmacologic models used by TCI systems is imperfect, especially regarding pharmacodynamic predictions. This shortcoming of TCI devices is not critical. That TCI systems produce steady-state effect-site concentrations at or near a specified target is a more important attribute than a high level of accuracy because anaesthesiologists titrate to a stable level of drug effect whatever the actual concentration is. In this sense, TCI functions as a 'gain switch'. Achieving a steady state is more important than perfect accuracy. [ABSTRACT FROM AUTHOR]

Summary: Introduction: Approximately 1% of the UK population take oral corticosteroids for ≥ 28 days each year, for broadly two reasons: deficiency in corticosteroid requiring replacement; or therapeutic corticosteroid for inflammatory conditions. Acute deficiency can occur at times of physiological stress (e.g. surgery), potentially leading to major complications. The Association of Anaesthetists' 2020 consensus guideline provides detailed advice for the management of glucocorticoids during the peri‐operative period for patients with adrenal insufficiency. This national audit aimed to assess compliance with this guideline. Methods: Data were collected from 59 Trusts over 14 consecutive days for all eligible patients undergoing procedures under the care of an anaesthetist. Patients who were prescribed ≥ 5 mg oral prednisolone equivalents pre‐operatively, in whom supplementary corticosteroid would be indicated, were compared with those prescribed < 5 mg oral prednisolone equivalents. Results: Operations for 21,731 patients were audited: 277 (1.3%) patients were taking therapeutic corticosteroids. Detailed peri‐operative data were collected for all patients receiving therapeutic corticosteroids: 201/277 (73%) were ASA physical status ≥ 3; 184/277 (66%) underwent elective procedures; and 252/277 (91%) were prescribed prednisolone pre‐operatively, of whom 219/277 (79%) were prescribed ≥ 5 mg oral prednisolone equivalents. In the patients who were prescribed ≥ 5 mg oral prednisolone equivalents, 186/219 (85%) received pre‐operative glucocorticoid supplementation and 97/219 (42%) received it postoperatively; however, only 67/219 (31%) and 43/219 (20%) respectively received glucocorticoid supplementation according to the guidelines. Overall, peri‐operative prescribing was compliant in 19/219 (9%) patients. A similar proportion, 30/219 (14%), received no supplementation. In the patients taking < 5 mg oral prednisolone equivalents pre‐operatively, 28/58 (48%) received inappropriate supplementation. Conclusions: Despite 125/277 (45%) of anaesthetists reporting Association of Anaesthetists' guidelines use, compliance remained low, with adherence in only 27/125 (22%) patients. Further research is required to identify the correct peri‐operative strategy for patients taking therapeutic corticosteroids. [ABSTRACT FROM AUTHOR]

Summary: Background: We analysed the clinical practice of anaesthesia associates in the UK, as reported to the 7th National Audit Project of the Royal College of Anaesthetists, and compared these with medically qualified anaesthetists. Methods: We included data from our baseline survey, activity survey and case registry as with other reports from the project. Results: Among 197 departments of anaesthesia, 52 (26%) employed anaesthesia associates. Of 10,009 responding anaesthesia care providers, 71 (< 1%) were anaesthesia associates, of whom 33 (47%) reporting working nights or weekends (compared with 97% of medically qualified anaesthetists in training and > 90% of consultants). Anaesthesia associates reported less training and confidence in managing peri‐operative cardiac arrest and its aftermath compared with medically qualified anaesthetists. Anaesthesia associates were less directly involved in the management and the aftermath of peri‐operative cardiac arrest than medically qualified anaesthetists, and the psychological impacts on professional and personal life appeared to be less. Among 24,172 cases, anaesthesia associates attended 432 (2%) and were the senior anaesthesia care provider in 63 (< 1%), with indirect supervision in 27 (43%). Anaesthesia associates worked predominantly in a small number of surgical specialties during weekdays and working daytime hours. Complication rates were low in cases managed by anaesthesia associates, likely reflecting case mix. However, activity and registry case mix data show anaesthesia associates do manage high‐risk cases (patients who are older, comorbid, obese and frail) with the potential for serious complications. Registry cases included higher risk cases with respect to the clinical setting and patient factors. Conclusion: Anaesthesia associates work in enhanced roles, relative to the scope of practice at qualification agreed by organisations. Recent changes mean the Royal College of Anaesthetists and Association of Anaesthetists do not currently support an enhanced scope of practice. [ABSTRACT FROM AUTHOR]

Objective: High quality obstetric anaesthetic care is integral to reducing preventable maternal deaths in Low-and-Middle-Income-Countries (LMICs). We applied behavioural science to evaluate SAFE Obstetrics, a 3-day Continuing Professional Development (CPD) course, on physician and non-physician anaesthetists' practice behaviours across 3 LMICs.Methods: Seven anaesthetist Fellows from Bangladesh, Nepal and Tanzania were trained in qualitative methods and behavioural science. Structured interviews were undertaken by Fellows and two UK behavioural scientists with course participants. Interviews were based on the Theoretical Domains Framework: a comprehensive framework of influences on behaviour change. Interviews were recorded, transcribed and analysed using content and thematic analysis.Results: 78 physician and non-physician anaesthetists participated (n = 26 Bangladesh, n = 24 Nepal and n = 28 Tanzania). Participants reported positive improvements in patient-centered working, safety, teamwork and confidence. Across countries, we found similar barriers and facilitators: environmental resources, a strong professional identity and positive social influences were key facilitators of change.Conclusion: This multi-country theory-based evaluation highlighted the impact of SAFE Obstetrics on participants' clinical practice. A supportive work environment was crucial for implementing learning following training; CPD courses in LMICs must furnish participants with skills and equipment to address training implementation challenges. Building local behavioural science capacity can strengthen LMIC health intervention evaluations. [ABSTRACT FROM AUTHOR]

Background: Inadequate postoperative analgesia greatly affects the recovery of patients, can poses a substantial health and economic burden. Patient-controlled analgesia is the most commonly used method for postoperative pain relief. However, the situation of inadequate analgesia still exists. Artificial intelligent Patient-controlled analgesia (Ai-PCA) system can make it easier for medical staff to understand the pain level of patients in order to deal with it in time. So far, several studies have investigated anesthesiologists' knowledge and management of Ai-PCA. Objective: This study aimed to assess the degree of anesthesiologists' knowledge, attitude and their practice (KAP) towards Ai-PCA in east China's Jiangsu Province. Methods: This cross-sectional study was conducted among 396 anesthesiologists working in tertiary hospitals. The data were collected using a pretested, structured and self-administered KAP questionnaire. The data were analyzed using Independent t-test, analysis of variance, Pearson's correlation and multiple linear regression tests. Results: Five hundred twelve questionnaires were collected, 396 anesthesiologists (190 Male, and 206 Female) were included in our study for statistical analysis. The score of knowledge, attitude, practice was 5.49 ((SD = 1.65; range:0–8), 37.45 (SD = 4.46; range:9–45), and 26.41 (SD = 9.61; range:9–45), respectively. Among the participants, 309 (78%) and 264 (66.7%) had good knowledge and positive attitudes toward Ai-PCA, respectively. However, only 81 (20.5%) of the participants exhibited good practice regarding Ai-PCA. Participation in Ai-PCA training showed a significant correlation with knowledge, attitude and practice scores. Besides, age, years of experience and professional titles of anesthesiologists were correlated with knowledge scores. The title of the anesthesiologist was associated with attitude scores. And the marital status of anesthesiologists was correlated with practice scores. Conclusion: Our findings revealed the score of practice regarding Ai-PCA are very poor among anesthesiologists in east China's Jiangsu Province. The utilization of Ai-PCA was found to be impacted by whether the individual had received training. This calls for a comprehensive approach should be conducted for raising the level of knowledge, attitude, and practice of anesthesiologist on using Ai-PCA and more Ai-PCA training to be included in the daily learning.

Sedation and anesthesia are often required in order to facilitate collection of high-quality imaging studies free of significant motion artifact for infants and neonates. Provision of safe sedation and anesthesia requires good communication between the ordering provider, radiologist, and anesthesiologist, careful pre-procedural evaluation of the patient, and availability of appropriate and sufficient equipment, drugs, personnel, and facilities. There are many additional factors to be considered for provision of safe sedation or anesthesia for infants and neonates—it is ideal to involve a fellowship-trained pediatric anesthesiologist in the planning and carry-out of these plans. In this review, we discuss some of the basic definitions of sedation and anesthesia, requirements for safe sedation and anesthesia, and many of the germane risks and additional considerations that factor into the delivery of a safe sedation or anesthesia plan for the imaging of an infant or neonate.

Summary Background Methods Results Conclusions Poor wellbeing and stress in UK anaesthetic trainees impacts significantly on clinical performance, workforce retention and patient care. This study aimed to provide an overview of the evidence in this field and to explore the factors affecting wellbeing and stress in UK anaesthetic trainees.MEDLINE, Embase, PsycINFO, and ERIC were searched, in addition to organisational websites. Literature reporting factors affecting wellbeing and stress in UK anaesthetic trainees from 2009 to present were included.Following exclusions, 45 studies were identified. Only five papers included qualitative analyses. Within these studies, 28 different phenomena related to wellbeing and stress were investigated. Thirty‐one different factors affecting anaesthetic trainees' wellbeing and stress were identified in this review. These have been summarised as individual; training; clinical role; progression; work patterns; resources; rest; support; and cultural factors. External factors were described as affecting wellbeing and stress more frequently than internal factors. The most frequently cited individual factors were fatigue and pre‐existing health status.The wide scope of phenomena of interest and measurement tools emphasises the challenge of defining and researching the concept of wellbeing. Despite these limitations, we have created a novel conceptual model of individual and external factors affecting UK anaesthetic trainees' wellbeing and stress. This supports an increased awareness and understanding of these factors, so that improvements can be made to practice and policy. [ABSTRACT FROM AUTHOR]

Background: The primary objective of anesthesiologists during the induction of anaesthesia is to mitigate the operative stress response resulting from endotracheal intubation. In this prospective, randomized controlled trial, our aim was to assess the feasibility and efficacy of employing Index of Consciousness (IoC, IoC1 and IoC2) monitoring in predicting and mitigating circulatory stress induced by endotracheal intubation for laparoscopic cholecystectomy patients under general anesthesia (GA). Methods: We enrolled one hundred and twenty patients scheduled for laparoscopic cholecystectomy under GA and randomly allocated them to two groups: IoC monitoring guidance (Group T, n = 60) and bispectral index (BIS) monitoring guidance (Group C, n = 60). The primary endpoints included the heart rate (HR) and mean arterial pressure (MAP) of the patients, as well as the rate of change (ROC) at specific time points during the endotracheal intubation period. Secondary outcomes encompassed the systemic vascular resistance index (SVRI), cardiac output index (CI), stroke volume index (SVI), ROC at specific time points, the incidence of adverse events (AEs), and the induction dosage of remifentanil and propofol during the endotracheal intubation period in both groups. Results: The mean (SD) HR at 1 min after intubation under IoC monitoring guidance was significantly lower than that under BIS monitoring guidance (76 (16) beats/min vs. 82 (16) beats/min, P = 0.049, respectively). Similarly, the mean (SD) MAP at 1 min after intubation under IoC monitoring guidance was lower than that under BIS monitoring guidance (90 (20) mmHg vs. 98 (19) mmHg, P = 0.031, respectively). At each time point from 1 to 5 min after intubation, the number of cases with HR ROC of less than 10% in Group T was significantly higher than in Group C (P < 0.05). Furthermore, between 1 and 3 min and at 5 min post-intubation, the number of cases with HR ROC between 20 to 30% or 40% in Group T was significantly lower than that in Group C (P < 0.05). At 1 min post-intubation, the number of cases with MAP ROC of less than 10% in Group T was significantly higher than that in Group C (P < 0.05), and the number of cases with MAP ROC between 10 to 20% in Group T was significantly lower than that in Group C (P < 0.01). Patients in Group T exhibited superior hemodynamic stability during the peri-endotracheal intubation period compared to those in Group C. There were no significant differences in the frequencies of AEs between the two groups (P > 0.05). Conclusion: This promising monitoring technique has the potential to predict the circulatory stress response, thereby reducing the incidence of adverse reactions during the peri-endotracheal intubation period. This technology holds promise for optimizing anesthesia management. Trail registration: Chinese Clinical Trail Registry Identifier: ChiCTR2300070237 (20/04/2022). [ABSTRACT FROM AUTHOR]

Background: Mentorship is crucial to career advancement, medical education, and psychosocial support, especially for women and minorities. Although anesthesia mentoring programs have shown promise, there are no survey data regarding mentor-mentee relationship dynamics. This study aimed to explore the dynamics of the anesthesia mentor/mentee relationship. Methods: A open cross-sectional web-based survey was distributed by the European Society of Anesthesiology and Intensive Care and European Society of Regional Anesthesia to European anesthesiologists. Participation was anonymous and consent was obtained. The study evaluated responses relating to preferences, facilitators, and barriers to mentorship relationships along with sociodemographic information. Results: In total, 543 anesthesiologists responded to the survey, and 406 (111 mentees, 49 mentors, 193 both, 53 neither) responded to questions regarding mentorship. 184 anesthesiologists identified as woman and 22 as other genders (non-binary, transgender, gender-fluid, and self-described gender). Moreover, 250 anesthesiologists identified as white. Both mentors and mentees indicated that personal compatibility was the most important factor for successful mentorship. Barriers to mentorship included time consumption and perceived lack of interest from the mentor and mentee. Both mentors and mentees benefited from this relationship. The former reported feeling helpful, and the latter supported the development of clinical skills. The mentors indicated that their participation was important for protecting against burnout/exhaustion and impostor syndrome. Participants reported a preference for mentorship programs organized at the departmental level, offered at the start of the anesthesiology education curricula. Women were more likely to feel a 'lack of interest' in mentoring them as a barrier (OR = 2.49, P = 0.033). Gender was a barrier for mentors of other genders (OR = 23.9, P = 0.0027) and ethnicity (OR = 48.0, P = 0.0023). White mentees found gender (OR = 0.14, P = 0.021) and ethnicity (OR = 0.11, P = 0.048) to be less important barriers to successful mentorship relationship. Conclusion: When possible, programs should prioritize matching mentors and mentees based on personal compatibility and experience in the mentee's area of interest. Addressing the perceived lack of interest in mentoring is essential for promoting diversity, equality, and inclusion within anesthesiology, as well as and uplifting women and minorities.

Background: One of the core indicators recommended by the Lancet Commission is surgical workforce density, aiming to improve the number of surgery, anesthetists, and obstetric (SAO) providers to 20 per 100,000 population by 2030. We assessed SAO workforce capacity in Somalia and made recommendations for improvement. Method: A cross‐sectional study was conducted using a structured questionnaire from the WHO Program for Global Surgery and Social Change (PGSSC) Surgical Assessment Tool. All hospitals that offer surgical care services were included. A descriptive analysis was conducted using the statistical software SPSS. Results: Of the 55 surveyed facilities providing surgical care services, 28 (50.9%) were public, mainly in urban areas. We found that there were 474 SAO specialists and non‐specialists (SAO providers) and 446 other important personnel (e.g., midwives, radiologists, and pathologists). Out of 474 SAOs, Banadir had 288. Overall, surgery specialties were the most prevalent profession among SAO providers' workforce, accounting for 160 (33.7%) surgery specialists, with 1.2 per 100,000 population. The six states of Somalia have 54 OB/GYN specialists (0.4 per 100,000 population). There were a total of 22 anesthesia specialists, with a ratio of 0.2 anesthesia specialists per 100,000 population. Conclusion: We found a serious shortage of the SAO workforce in Somalia, and it is unlikely to meet the 2030 Lancet Commission on Global Surgery targets. There is a need for additional training of SAO providers who can offer effective leadership in surgical care services to combat the extremely avoidable surgical‐related morbidities and mortalities.

As the demand for advanced bronchoscopic procedures increases, prolonged sedation with adequate oxygenation has become essential. Traditionally, these procedures require an anesthesiologist to provide (positive‐pressure or jet) ventilator support. However, recent innovations have enabled advanced bronchoscopy under high‐flow endotracheal oxygenation and deep sedation without these requirements. Following oropharyngeal lidocaine anaesthesia, deep sedation was induced using fentanyl and remimazolam. Thereafter lidocaine was instilled into the larynx, trachea, and main bronchi using a flexible bronchoscope with a spray catheter. Finally, either an uncuffed endotracheal tube (Case 1) or a rigid bronchoscope (Case 2) was inserted, and advanced bronchoscopic procedures, such as cryobiopsy and stent insertion, were successfully performed without a ventilator or an anesthesiologist. Our novel technique is expected to facilitate the easier and adequate performance of advanced high‐level bronchoscopic procedures by pulmonologists, even in resource‐limited settings.

Background: Supraclavicular brachial plexus blockade (SBPB) is commonly performed regional anesthetic technique for forearm and hand surgeries, and its blockage provides good surgical anesthesia. Aim: Considering the efficacy of adjuvant for ropivacaine in SBPBs, we designed a double-blind randomized control study to compare the characteristics and side effects of ropivacaine along with dexamethasone versus dexmedetomidine in SBPBs in patients scheduled for upper limb surgeries. Material and Methods: Present study was single-center, prospective, randomised, double blind study, conducted patients aged 18-70 years, belonging to American Society of Anaesthesiologists physical status (ASA) of I or II, scheduled for Upper limb surgeries under SBPB. Results: In present study, 108 patients were studied, 54 patients received 20 ml 0.5% Ropivacaine with 50 mcg Dexamethasone (Group A, n=54), while other 54 patients received 20 ml 0.5% Ropivacaine with 50 mcg Dexmedetomidine (Group B, n=54). Age, weight, gender, ASA grade & duration of surgery were comparable in both groups. Dexamethasone group has earlier onset of sensory block, earlier onset of motor block, prolonged duration of sensory block & prolonged duration of motor block as compared to dexmedetomidine group & difference was statistically significant (p< 0.05). Dexamethasone group duration of analgesia, delayed first rescue analgesic requirement & less doses of rescue analgesia required as compared to dexmedetomidine group & difference was statistically significant (p< 0.05). Conclusion: Dexamethasone is a better alternative than dexmedetomidine since it shortens the onset of sensory and motor block, prolongs the duration of sensory and motor block and prolongs the duration of analgesia.

The article focuses on the lack of standardized ethics training in U.S. anesthesiology programs and the unique ethical challenges faced by anesthesiologists. Topics include the variation in ethics education across programs, key ethical issues identified by anesthesia experts such as consent and end-of-life care, and the need for integrating more ethics content within the constraints of existing curricula.

Background: This article gives the pediatric anesthesia perspective from Cameroon, Nigeria, Ghana, Liberia, and Gambia, five out of six countries in Anglophone West Africa. Over 40% of the population of most of these countries are younger than 14 years and there is an increasing need for paediatric anesthesia services. Findings: Workforce density ranges from 0.08 to 0.58 physician anesthesia providers per 100,000 population. There are only 13 trained pediatric anesthetists; ratios range from 0 to 0.4 per 100,000 children, thus pediatric anesthesia services are provided by various cadres of physician and non‐physician anesthesia providers. Physician anesthesia training is mostly carried out by the West African College of Surgeons as well as national postgraduate colleges. Pediatric anesthesia services are provided in tertiary (teaching), secondary (general), district, faith‐based, military, private hospitals and through surgical missions. Challenges include lack of trained personnel, high morbidity from late presentation to health facilities and financial constraints, lack of health insurance for pediatric anesthesia services, unavailability of appropriate equipment and consumables, a narrow range of medications, very few pediatric‐specific operating theaters, and inadequate critical care services. Solutions: The lack of opportunities for sub‐specialty training in pediatric anesthesia in West Africa is currently being addressed in Nigeria and Ghana. Non‐governmental agencies fund programs and courses related to pediatric anesthesia and have also provided fully equipped operating theaters. Advocacy for pediatric anesthesia can be achieved through the National Surgical Obstetric Anesthesia and Nursing Plans Implementation Committee of the various countries. There is an urgent need for prioritization of health in the budgets of Anglophone West African countries and governments must deliberately provide support for anesthesia and surgical services. More international collaborations towards workforce training and creation of children's hospitals are needed. [ABSTRACT FROM AUTHOR]

The US Centers for Medicare and Medicaid Services provide guidelines for the coverage of anaesthesia residents and certified registered nurse anaesthetists (CRNAs) by anaesthesiologists. We tested the hypothesis that changes in the anaesthesia staffing model increase billing compliance. We analysed 13 926 anaesthesia cases performed between September 2019 and November 2019 (baseline), and between September 2020 and November 2020 (after change in staff model) at a US academic medical centre using an estimation tool. The intervention was assignment of additional 12-h weekday CRNAs plus an additional anaesthesiologist who covered weekdays after 17:00, weekends, and holidays. The proportion of cases with billing compliant coverage (covered either by solo anaesthesiologist or anaesthesiologist covering two or fewer residents or four or fewer CRNAs) was analysed using logistic and segmented regression analyses. The change in staff model was associated with a decrease in non-optimal anaesthesia staff assignments from 4.2% to 1.2% of anaesthesia cases (adjusted odds ratio 0.25; 95% confidence interval [CI] 0.20–0.32; P <0.001) and an increase in billable anaesthesia units of 0.6 per anaesthesia case (95% CI 0.4–0.8; P <0.001). An increased revenue margin associated with optimal staffing levels would only be achieved with salary levels at the 25th percentile of relevant benchmark compensation levels. Total staff overtime for all anaesthesia providers decreased (adjusted absolute difference −4.1 total overtime hours per day; 95% CI −7.0 to −1.3; P =0.004). Implementation of a change in anaesthesia staffing model was associated with improved billing compliance, higher billable anaesthesia units, and reduced overtime. The effects of the anaesthesia staff model on revenue and financial margin can be determined using our web-based margin-cost estimation tool. [ABSTRACT FROM AUTHOR]

Guideline adherence in the medical field leaves room for improvement. Digitalised decision support helps improve compliance. However, the complex nature of the guidelines makes implementation in clinical practice difficult. This single-centre prospective study included 204 adult ASA physical status 3–4 patients undergoing elective noncardiac surgery at a German university hospital. Agreement of clearance for surgery between a guideline expert and a digital guideline support tool was investigated. The decision made by the on-duty anaesthetists (standard approach) was assessed for agreement with the expert in a cross-over design. The main outcome was the level of agreement between digital guideline support and the expert. The digital guideline support approach cleared 18.1% of the patients for surgery, the standard approach cleared 74.0%, and the expert approach cleared 47.5%. Agreement of the expert decision with digital guideline support (66.7%) and the standard approach (67.6%) was fair (Cohen's kappa 0.37 [interquartile range 0.26–0.48] vs 0.31 [0.21–0.42], P =0.6). Taking the expert decision as a benchmark, correct clearance using digital guideline support was 50.5%, and correct clearance using the standard approach was 44.6%. Digital guideline support incorrectly asked for additional examinations in 31.4% of the patients, whereas the standard approach did not consider conditions that would have justified additional examinations before surgery in 29.4%. Strict guideline adherence for clearance for surgery through digitalised decision support inadequately considered patients, clinical context. Vague formulations, weak recommendations, and low-quality evidence complicate guideline translation into explicit rules. NCT04058769. [ABSTRACT FROM AUTHOR]

Background: The National Health Service (NHS) has pledged to reach carbon net-zero by 2040. In alignment with this goal, a London hospital's anaesthesia department is actively reducing desflurane use and transitioning towards total intravenous anaesthesia (TIVA) as a sustainable alternative, contributing to environmentally responsible practices within the healthcare sector. Methods: We conducted a rapid qualitative appraisal through online interviews with 17 anaesthetic practitioners to explore their perspectives regarding this climate change mitigation strategy. Data analysis was undertaken through the use of rapid appraisal sheets and a framework analysis method. Results: Participants highlighted the disadvantages of TIVA, including the increased effort, heightened monitoring requirements, operational challenges, and a lack of clinical confidence associated with its use. Despite these reservations, participants acknowledged TIVA's potential to reduce postoperative nausea. There were perceptions that senior staff members might resist this change due to habits and scepticism over its impact on climate change. To facilitate greater TIVA adoption, participants recommended enhanced training, the implementation of a dashboard to raise awareness of greenhouse gas (GHG) emissions, and the presence of strong climate change leadership within the department. Participants believed that a shift to TIVA should be followed by specific measures such as addressing waste management which is crucial for GHG reduction, emphasising the perceived link between waste and emissions. Conclusions: The evaluation examines stakeholder attitudes, perceptions, and behaviours, focusing on transitioning from desflurane to TIVA. The study highlights the importance of staff engagement, organisational support, and underscores the crucial role that healthcare practitioners and leadership play in fostering sustainability within the healthcare sector.

Increased patient access to electronic medical records and resources has resulted in higher volumes of health-related questions posed to clinical staff, while physicians' rising clinical workloads have resulted in less time for comprehensive, thoughtful responses to patient questions. Artificial intelligence chatbots powered by large language models (LLMs) such as ChatGPT could help anesthesiologists efficiently respond to electronic patient inquiries, but their ability to do so is unclear. A cross-sectional exploratory survey-based study comprised of 100 anesthesia-related patient question/response sets based on two fictitious simple clinical scenarios was performed. Each question was answered by an independent board-certified anesthesiologist and ChatGPT (GPT-3.5 model, August 3, 2023 version). The responses were randomized and evaluated via survey by three blinded board-certified anesthesiologists for various quality and empathy measures. On a 5-point Likert scale, ChatGPT received similar overall quality ratings (4.2 vs. 4.1, p =.81) and significantly higher overall empathy ratings (3.7 vs. 3.4, p <.01) compared to the anesthesiologist. ChatGPT underperformed the anesthesiologist regarding rate of responses in agreement with scientific consensus (96.6% vs. 99.3%, p =.02) and possibility of harm (4.7% vs. 1.7%, p =.04), but performed similarly in other measures (percentage of responses with inappropriate/incorrect information (5.7% vs. 2.7%, p =.07) and missing information (10.0% vs. 7.0%, p =.19)). In conclusion, LLMs show great potential in healthcare, but additional improvement is needed to decrease the risk of patient harm and reduce the need for close physician oversight. Further research with more complex clinical scenarios, clinicians, and live patients is necessary to validate their role in healthcare. [ABSTRACT FROM AUTHOR]

Background. Excessive operating room noise impairs communication, distracts from monitoring equipment, and may increase patient and provider stress. Aim. This study investigates the effects of reduced noise on perioperative behavior in children undergoing general anesthesia and on anesthesia provider response time. Methods. Healthy children (the American Society of Anesthesiologists class I‐II), 2–8 years of age, and their anesthesia providers were randomized into a control or treatment group exposed to reduced stimulation during induction and emergence. Primary outcomes were patient behavior and provider response time. Secondary outcomes were postoperative pain scores, provider responses exceeding 30 seconds, and median and maximum noise exposure. Results. 64 children (27 females and 37 males) were randomized into a control or treatment group, of whom 32 (50%) underwent tonsillectomy/adenoidectomy and 32 (50%) underwent dental procedures. The average age was 4.6 (SD 1.43) years. Children exposed to reduced noise were less likely to be "fussy about eating" (p = 0.042), more "interested in what goes on around them" (p = 0.008), and had fewer temper tantrums (p = 0.004) on postoperative day one or two and on postoperative day five, six, or seven. No other differences were found between groups in behavioral assessment scores or provider response times. Conclusions. Our study is the first to show that a low‐stimulus environment improves postdischarge behavior. Provider response time was unaffected by reduced noise, and the average and peak noise exposure levels did not exceed national safety guidelines. This trial is registered with NCT03507855 and NCT03504553. [ABSTRACT FROM AUTHOR]

With the increasing prevalence of obesity and morbid obesity, this subgroup's contribution to patients presenting for elective procedures requiring sedation is significant. Gastrointestinal (GI) procedures clearly form the largest group of such procedures. These procedures may be intended to treat obesity such as the insertion of an intragastric balloon or one or more unrelated procedures such as a screening colonoscopy and (or) diagnostic/therapeutic endoscopy. Regardless of the procedure, these patients pose significant challenges in terms of choice of sedatives, dosing, airway management, ventilation, and oxygenation. An understanding of dissimilarity in the handling of different groups of medications used by an anesthesia provider and alterations in airway anatomy is critical for providing safe sedation. Administration of sedative medications and conduct of anesthesia requires dose modifications and airway adjuncts. In this review, we discuss the above issues in detail, with a particular focus on GI endoscopy. [ABSTRACT FROM AUTHOR]

Introduction: Venous thromboembolism (VTE), including deep venous thrombosis and pulmonary embolism, is a common and potentially fatal post-surgery complication. Research has shown that 50% of VTE causes are intraoperative, with the risk of occurrence highest during and immediately post-surgery. Therefore, strategies for early assessment and prevention should be established. Objective: To identify optimal equipment selection, compression protocols, and strategies for complication prevention and management during intraoperative intermittent pneumatic compression (IPC), this study aims to synthesize the best available evidence. The objective is to inform accurate risk assessment and facilitate early mechanical prophylaxis against venous thrombosis. Methods: The Practical Application to Clinical Evidence model proposed by the Joanna Briggs Institute was utilized. Indicators were identified using the available best evidence from January 2023 to October 2023, and a baseline review was conducted. Negative factors were identified based on clinical evidence-based practice. The implementation rates of different indicators before (n = 372) and after (n = 405) evidence-based practice, the incidence rates of intraoperative IPC-related adverse events and VTE, and the risk of venous thrombosis before (n = 50) and after (n = 50) practice were identified and compared. Furthermore, medical staff's knowledge of best practices for intraoperative IPC was assessed through pre- and post-intervention surveys involving 109 operating room personnel. Results: All review indicators significantly improved (P < 0.01) after the evidence-based practice, and 9 reached 100%. Two intraoperative venous thrombosis events occurred before the evidence-based practice, with an incidence rate of 0.53%; no intraoperative venous thrombosis event occurred after the evidence-based practice, with no significant difference (X2 = 2.171, P = 0.141 > 0.05). However, there were significant differences in intraoperative venous blood hemodynamics before and after the practice (P < 0.05). Moreover, 9 IPC-related adverse events, including 4 cases of skin pressure, 3 cases of skin allergy, and 2 cases of lower limb circulation disorders, were reported before the evidence-based practice, with an incidence rate of 2.4%. Notably, no intraoperative IPC-associated adverse events occurred after the evidence-based practice(X2 = 9.913, P < 0.01). Meanwhile, the score of comprehension of the standard utilization of IPC for preventing venous thrombosis by medical staff in the operating room was 93.34 ± 3.64 after the evidence-based practice, which was higher than that (67.55 ± 5.45) before the evidence-based practice. Overall, the clinical practice was significantly improved the evidence-based practice. Conclusions: Applying intraoperative IPC utilization standards based on the best evidence in clinical practice effectively reduces the intraoperative IPC-associated adverse event rate and the risks of intraoperative venous thrombosis. It also improves the execution rates and compliance with mechanical prevention standards in the operating room by medical staff. Future research should prioritize the development and refinement of best clinical practices for intraoperative venous thrombosis prevention, with a particular emphasis on the integration of mechanical prophylaxis strategies.

Background: The American Society of Anesthesiologists (ASA) classification is the most used system to assess patient health status before surgery, ranging from I to V levels. This study aims to explore the impact of different ASA risk classes (ASA II [mild risk] and ASA III [severe risk]) on clinical outcomes following hip fracture surgery, including all-cause mortality and postoperative complications. Methods: A retrospective analysis from 2019 to 2021 across three Jordanian centers was conducted. The study included patients aged 65 and above who underwent hip fracture repair surgeries. Preoperative measures, intraoperative management protocols, and postoperative care were collected. Clinical data were extracted from electronic medical records, including demographics, fracture type, intraoperative data, and postoperative outcomes. Results: The analysis included 1033 patients, with 501 (48.5%) in the mild anesthetic risk group (ASA I-II) and 532 (51.5%) in the severe anesthetic risk group (ASA III-V). The mean age was 73 years, with a higher prevalence of males in the severe risk group. Patients in the severe risk group had more comorbidities, higher ICU admissions (15.23% vs. 6.18%), longer hospital stays (median 7 vs. 6 days), and higher rates of postoperative thromboembolic complications (3.39% vs. 1.39%) compared to the mild risk group. Additionally, the severe risk group showed higher mortality rates both in-hospital mortality (3.38% vs. 1.39%) and all-cause mortality (16.92% vs. 10.36%). Multivariate analysis identified higher ASA score as independent risk factors for increased all-cause mortality (HR = 1.64 95%CI 1.51–2.34) and thromboembolic complications (OR = 2.85 95%CI 1.16-7). Length of hospital stay was significantly associated with higher ASA score (OR = 1.04 95%CI 0.96–1.11). Conclusion: The study underscores the significant impact of anesthetic risk on the outcomes of hip fracture surgeries. Patients with higher ASA scores associated with severe systemic diseases may have at increased risk of adverse outcomes. [ABSTRACT FROM AUTHOR]

Summary: Background: There are concerns that airway management in patients with suspected or confirmed cervical spine injury may exacerbate an existing neurological deficit, cause a new spinal cord injury or be hazardous due to precautions to avoid neurological injury. However, there are no evidence‐based guidelines for practicing clinicians to support safe and effective airway management in this setting. Methods: An expert multidisciplinary, multi‐society working party conducted a systematic review of contemporary literature (January 2012–June 2022), followed by a three‐round Delphi process to produce guidelines to improve airway management for patients with suspected or confirmed cervical spine injury. Results: We included 67 articles in the systematic review, and successfully agreed 23 recommendations. Evidence supporting recommendations was generally modest, and only one moderate and two strong recommendations were made. Overall, recommendations highlight key principles and techniques for pre‐oxygenation and facemask ventilation; supraglottic airway device use; tracheal intubation; adjuncts during tracheal intubation; cricoid force and external laryngeal manipulation; emergency front‐of‐neck airway access; awake tracheal intubation; and cervical spine immobilisation. We also signpost to recommendations on pre‐hospital care, military settings and principles in human factors. Conclusions: It is hoped that the pragmatic approach to airway management made within these guidelines will improve the safety and efficacy of airway management in adult patients with suspected or confirmed cervical spine injury.

Summary: Frailty increases peri‐operative risk, but details of its burden, clinical features and the risk of, and outcomes following, peri‐operative cardiac arrest are lacking. As a preplanned analysis of the 7th National Audit Project of the Royal College of Anaesthetists, we described the characteristics of older patients living with frailty undergoing anaesthesia and surgery, and those reported to the peri‐operative cardiac arrest case registry. In the activity survey, 1676 (26%) of 6466 patients aged > 65 y were reported as frail (Clinical Frailty Scale score ≥ 5). Increasing age and frailty were both associated with increasing comorbidities and the proportion of surgery undertaken as an emergency. Except in patients who were terminally ill (Clinical Frailty Scale score 9), increasing frailty was associated with an increased proportion of complex or major surgery. The rate of use of invasive arterial blood pressure monitoring was associated with frailty only until Clinical Frailty Scale score 5, and then plateaued or fell. Of 881 cardiac arrests reported to the 7th National Audit Project, 156 (18%) were in patients aged > 65 y and living with frailty, with an estimated incidence of 1 in 1204 (95%CI 1 in 1027–1412) and a mortality rate of 1 in 2020 (95%CI 1 in 1642–2488), approximately 2.6‐fold higher than in adults who were not frail. Hip fracture, emergency laparotomy, emergency vascular surgery and urological surgery were the most common surgical procedures in older patients living with frailty who had a cardiac arrest. We report a high burden of frailty within the surgical population, requiring complex, urgent surgery, and the extent of poorer outcomes of peri‐operative cardiac arrest compared with patients of the same age not living with frailty.

The transversus abdominis plane (TAP) block is a regional anesthesia technique used as part of a multimodal pain management plan in patients undergoing abdominal surgery. There are numerous approaches and techniques described in the literature, resulting in a lack of consistency in block performance. This potentially reduces efficacy while increasing risk to the patient. Competency assessment tools have been shown to lower patient risk and improve outcomes by improving provider skill. Checklists are used as formative and summative assessment tools throughout healthcare education, however, there is no validated tool for ultrasound-guided TAP blocks. The purpose of this evidence-based project was to develop a checklist using a modified Delphi method. The primary outcome measure was validation of the assessment tool, established by an expert panel consensus and guided by Messick's validity framework. A 43-item checklist was validated by six certified registered nurse anesthesiologists throughout the United States with expertise in regional anesthesia. Three rounds of feedback were required to exceed the threshold of consensus (0.8), establishing a method of evaluation that may allow future research in educational settings through improved skill assessment among providers performing TAP blocks.

Background and Purpose: Tonsillectomy procedures are commonly performed worldwide. At our academic tertiary care facility, we perform approximately 1000 tonsillectomy procedures annually. We have found inconsistent pain management strategies in pediatric tonsillectomy patients have contributed to variability in postoperative complications and the number and types of postoperative pain medications required in the Post Anesthesia Care Unit (PACU). This project aimed to assess the impact of implementing a standardized perioperative pain management protocol on reducing postoperative complications in pediatric patients who underwent a tonsillectomy procedure. Methods: A pre‐post‐intervention design was utilized, comparing characteristics and outcomes of pediatric patients for whom a standardized perioperative pain management protocol was implemented over a 12‐week period compared to those who did not. The standardized perioperative pain management protocol was utilized intraoperatively by the anesthesiologists, nurse anesthetists, and residents. A Qualtrics survey was used by the Post Anesthesia Care Unit (PACU) nurses to gather data as they cared for patients who underwent tonsillectomy. Four outcomes were measured: (1) postoperative pain medication administration, (2) rate of postoperative respiratory complications, (3) rate of adherence, and (4) usability of a standardized pain management protocol. Data were compared between pre and post‐implementation groups. Results: During the quality improvement project, 180 children underwent tonsillectomy, with 81 in the control group and 99 in the intervention group. The median age did not differ between groups. The control group had higher postoperative opioid medication usage (93.8% vs. 54.5%) and a higher number of opioids administered in the recovery room. Postoperative IV fentanyl was reduced in the intervention group (49.4% vs. 28.3% in the intervention, p =.004). Respiratory interventions were more frequent in the control group (24.7% vs. 7.1%), with increased respiratory team activation. Respiratory team activation in the Post Anesthesia Care Unit (PACU) includes a 511 page for anesthesia provider assistance. Respiratory interventions included bag‐mask ventilation, lidocaine, propofol or succinylcholine administration, and reintubation. The intervention group had 100% adherence to the pain management protocol, and providers found it easy to use. Conclusion: The quality improvement project highlighted notable improvements in the intervention group for whom a standardized perioperative pain management protocol was used, including reduced opioid medication administration, lower incidence of respiratory interventions, and high adherence to the pain management protocol. These findings underscore the effectiveness and feasibility of standardized protocols in enhancing patient outcomes. [ABSTRACT FROM AUTHOR]

Children commonly refuse induction of anesthesia. Anesthesia providers must then decide whether to honor the child's dissent or to proceed over objection. In some circumstances, a forced induction involves restraining the child, incurring both practical and ethical harms to the patient‐provider encounter. This educational review explores the practical dilemma encountered when a child dissents to induction of anesthesia. In the course of exploring this dilemma, dissent and associated terms are defined and compared, and the prominent ethical underpinnings regarding pediatric decision‐making are described to clarify dissent as an ethical and practical concept. Important legal and professional standards are summarized, and practice trends are discussed to depict the current state of practice, including novel approaches to honoring pediatric dissent for elective surgeries. This information is then used to invite providers to consider where they ethically situate themselves within a legally and professionally defined space of acceptable practice. Finally, these considerations are synthesized to discuss important nuances regarding pediatric refusal, and some key questions are presented for clinicians to ponder as they consider their practice of choosing whether to honor pediatric dissent at induction.

Background: Digital modalities which enable asynchronous learning, such as audio podcasts and videos demonstrating procedures, may benefit acquisition and retention of knowledge and clinical skills. The main objective of this nationwide cross‐sectional survey study was to evaluate key aspects and factors related to usage of audio podcasts and procedural videos in anaesthesiology and intensive care. Methods: A 20‐item multiple‐choice‐question online survey was created through a consensus process including pilot testing among residents and consultants. Data were collected over a 3‐month period, September–November 2023. Results: The survey was completed by 466 anaesthetists. More than a third reported using procedural videos ≥1 time per week, whereas fewer than one in four participants used audio podcasts at least once per week. Multivariable logistic regression analysis showed that working at a university hospital, male sex, and younger age were independently associated with podcast use ≥1 time per week, with the highest odds ratio (OR) for younger age (<40 years vs. ≥40 years old; OR 5.86 (95% confidence interval 3.55–9.67), p <.001). Younger age was also significantly associated with higher frequency of video use (OR 1.71 (1.13–2.58), p =.011), while working predominantly in intensive care was associated with a lower frequency of video use. Podcasts were often used during commuting (42.3%), household work (30.7%), and exercise (24.9%), indicating a role in multi‐tasking. Approximately half of respondents expressed that audio podcast‐based learning has a moderate to very large positive impact on acquisition of theoretical knowledge, as well as practical skills. A vast majority, 85.2%, reported that procedural videos have a moderate to very large impact on development of clinical skills. Conclusion: Audio podcasts and procedural videos are appreciated tools with potential to supplement more traditional didactic techniques in anaesthesiology and intensive care. Procedural video use is common, with perceived large effects on development of clinical skills. Further data are needed to fully understand learning outcomes, quality of peer‐review processes, and potential sex‐differences. [ABSTRACT FROM AUTHOR]

Background: Specific guidelines to manage caesarean delivery anaesthesia are lacking. A European multicentre study, ACCESS investigates caesarean delivery anaesthesia management in European centres. In order to identify ACCESS participating centres, a registration survey was created. Objective: The aim of the current report is to describe the characteristics of ACCESS study participating centres, the rationale for the ACCESS study and the study methodology. Design and Setting: The ACCESS study is a European multicentre cross‐sectional study to describe anaesthesia management for caesarean delivery (CD) using a snapshot (2‐week) design. The ACCESS registration survey gathered: contact details for National Coordinators (NC); Lead Investigators (LI) per centre; centre annual CD volume; expected no. of CD during 2‐week snapshot window; centre practice information; data collection language. The ACCESS registration survey was launched July 2022 (Google Forms, Google Inc., Mountain View, CA, USA) and distributed through personal connections, national and international societies, social media networks, during Euroanaesthesia 2023, through the European Society of Anaesthesiology and Intensive Care newsletter. Results: The ACCESS registration survey identified Lead Investigators for 418 centres, in 32 countries, representing an anticipated number of 15,073 CD cases over the planned 12‐month study period. A median (range) of 20 (2 to 400) CD cases are anticipated per centre during the 2‐week snapshot window. Most 366/418 (87.6%) centres are small, ≤2000 annual CD cases, 42 are medium 2000–5000 cases and 10 are large, ≥5000 annual CD cases. Registered centres reported in 134 (32.0%) centres that anaesthesia for caesarean delivery is performed mostly by a specialist obstetric anaesthesiologist. Conclusion: The ACCESS registration survey revealed variability in volume and CD practice as well as training‐levels and staffing among European countries. The ACCESS study (https://www.access-study.org/) aims to generate practice data to guide CD anaesthetic management strategies. [ABSTRACT FROM AUTHOR]
