Objective: To assess perceptions, practice patterns, and barriers to adoption of transperineal prostate biopsy (TPBx) under local anesthesia., Methods: Providers from Michigan urological surgery improvement collaborative (MUSIC) and Pennsylvania urologic regional collaborative (PURC) were administered an online survey to assess beliefs and educational needs regarding TPBx. Providers were divided into those who performed or did not perform TPBx. The MUSIC and PURC registries were queried to assess TPBx utilization. Descriptive analytics and bivariate analysis determined associations between provider/practice demographics and attitudes., Results: Since 2019, TPBx adoption has increased more than 2-fold to 7.0% and 16% across MUSIC and PURC practices, respectively. Of 350 urologists invited to participate in a survey, a total of 91 complete responses were obtained with 21 respondents (23%) reported performing TPBx. Participants estimated the learning curve was <10 procedure for TPBx performers and non-performers. No significant association was observed between learning curve and provider age/practice setting. The major perceived benefits of TPBx were decreased risk of sepsis, improved cancer detection rate and antibiotic stewardship. The most commonly cited challenges to implementation included access to equipment and patient experience. Urologists performing TPBx reported learning curve as an additional barrier, while those not performing TPBx reported duration of procedure., Conclusion: Access to equipment and patient experience concerns remain substantial barriers to adoption of TPBx. Dissemination of techniques utilizing existing equipment and optimization of local anesthetic protocols for TPBx may help facilitate the continued adoption of TPBx., Competing Interests: Declaration of Competing Interest Brian Stork stock holder for Greater Michigan Lithotripsy, Muskegon Surgery Center, Theralogix IV, Michigan Mobile Urology Services and partner in MED5 (StomaCloak).

Background: Office-based surgery can increase logistical and financial efficiency for patients and surgeons. The current study compares wide-awake, office-based carpal tunnel release to wide-awake operations performed in the operating room in terms of volume, financial burden, narcotic prescriptions, and adverse events., Methods: Operations performed under local-only anesthesia from 2010 to 2020 were identified in a national administrative database (PearlDiver). Patients were grouped by surgical setting and matched based on age, sex, comorbidity burden, and geographic region. Primary endpoints included total disbursement and physician reimbursement, and 30-day narcotics prescriptions, emergency department (ED) visits, and surgical site infections (SSIs)., Results: Before matching, there were 303,741 operating room operations and 5463 office operations. From 2010 to 2020, the percentage of operations in the office increased from 1.2% to 3.4%. Matched cohorts included 21,835 operating room operations and 5459 office operations. Office surgery was associated with lower total disbursement and physician reimbursement for patients with commercial insurance, Medicaid, and Medicare. Linear regression modeling indicated that office-based surgery was significantly associated with lower total disbursement and physician reimbursement. Fewer office patients filled narcotic prescriptions and visited the ED, and there was no difference in SSIs., Conclusions: Compared with operating room surgery, office surgery was associated with lower financial burden, fewer narcotics prescriptions and ED visits, and a similar incidence of SSIs. These findings, together with literature showing greater efficiency in the office, suggest that office-based operations are safe and cost-effective and should continue to grow., Clinical Question/level of Evidence: Therapeutic, III., (Copyright © 2023 by the American Society of Plastic Surgeons.)

Background: Cost, efficiency, patient preference, and safety have driven utilization of wide awake, local anesthesia, no tourniquet (WALANT) in hand surgery. This is not well documented in adolescents. We hypothesize that the use of WALANT with adolescents reduced time spent in the operating room (OR) and in the hospital when compared with patients who underwent surgery with traditional anesthesia (TA)., Methods: After institutional review board approval, we performed a retrospective review of patients aged 10 to 17 who underwent surgery at a regional hospital system including the level 1 pediatric trauma hospital. Operative notes were assessed for use of WALANT. We excluded those operations not traditionally amenable to WALANT. Using a propensity matched cohort, hospital time, OR time, and perioperative complications were recorded and compared to evaluate efficiency and perioperative safety., Results: There were 28 cases in the WALANT group and 28 cases in the TA group after excluding cases not amenable to WALANT, and cases were propensity matched. Although the operative time (incision to closure) was similar, for WALANT patients, the in-room to procedure time (15 vs 22 minutes), procedure end to out-room time (5 vs 10 minutes), total room time (52.81 vs 63.68), and length of hospital stay (222 vs 342 minutes) were shorter than patients in the TA group., Conclusion: Our case series demonstrates time-savings both in the OR and in the hospital overall. Avoiding TA when WALANT is feasible may result in significant savings to hospital systems, patients, and payers while also freeing up anesthesia staff and perioperative nurses., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Local anesthesia (LA) for open umbilical hernia tissue repair (OUHTR) is not widely utilized in academic centers in the United States. We hypothesize that LA for OUHTR is feasible in a veteran patient population., Methods: From 2015 to 2019, 449 umbilical hernias were repaired at our institution utilizing a standardized technique in veteran patients. OUHTR was included in this analysis (n = 283). Since 2017, 18.7% (n = 53) UH were repaired under LA. We compared outcomes and operative times between general anesthesia and LA in patients undergoing OUHTR. Univariable and multivariable analyses were performed to determine significance., Results: The entire cohort was composed of older (56.3 ± 12.1 years), White (75.5%), obese (body mass index [BMI] = 32.3 ± 4.6 kg/m2) men (98.0%). The average hernia size for the entire cohort was 2.42 ± 1.2 cm. The groups were similar in age and BMI. Patients with higher American Society of Anesthesiologists (ASA) (Odds ratio [OR] 3.1; 95% CI 1.5-6.8) and cardiovascular disease (OR 2.7; 95% CI 1.0-7.2) were more likely to receive LA. Recurrence (0.0% vs 6.0%; P = .9) and 30-day complications (6.0% vs 13%; P = .9) were similar between LA and GA after correcting for hernia size. Operating room times were reduced in the LA group (17.7 minutes; P < .05). None of the patients with LA required postanesthesia care unit for recovery. The patients who received LA reported being comfortable (78.9% of patients), with the worst reported pain being 2.4 ± 2.4 (out of a scale of 10), and 94.7% would elect to receive LA if they had another hernia repair., Conclusion: Patients who received LA had more cardiac disease and a higher ASA. Complications were similar between both groups. LA reduced operating room times. Patients were satisfied with LA.

Aim: To systematically and meta-analytically examine the efficacy of ropivacaine versus lidocaine infiltration for controlling postpartum perineal pain secondary to spontaneous tear or selective episiotomy., Methods: We searched four databases from inception to 20-September-2020. We included all relevant randomized and nonrandomized studies and assessed their risk of bias. We pooled data as standardized mean difference (SMD), weighted mean difference (WMD), or odds ratio (OR) with 95 % confidence intervals (95 % CIs)., Results: Four studies met the inclusion criteria (one and three studies were nonrandomized and randomized, respectively). There were 405 patients; 205 and 200 patients received lidocaine and ropivacaine, respectively. There was no significant difference between ropivacaine and lidocaine groups with regard to visual analogue scale (VAS) pain scores at suturing (WMD = -0.04, 95 % CI [-0.41, 0.32], P = 0.82), 2 h (SMD = -1.50, 95 % CI [-3.50, 0.50], P = 0.14), and 24 h (SMD = -0.40, 95 % CI [-1.15, 0.34], P = 0.29) post repair of perineal trauma. Proportion of patients with mild VAS pain score ≤3 at 24 h was significantly higher in the ropivacaine group (OR = 4.34, 95 % CI [2.03, 9.29], P < 0.001). Proportion of patients who did not require additional analgesia during the first 24 h post perineal repair did not significantly differ between both groups (OR = 2.44, 95 % CI [0.09, 68.21], P = 0.60). Ropivacaine group achieved higher maternal satisfaction (OR = 7.13, 95 % CI [3.63, 13.99], P < 0.001)., Conclusions: During repair of postpartum perineal trauma, pain efficacy is relatively longer with ropivacaine but safety is not well investigated. High-quality and large-sized studies are needed to consolidate these findings., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2021 Elsevier Masson SAS.

Background: Many studies have identified racial disparities in healthcare, but few have described disparities in the use of anesthesia modalities. We examined racial disparities in the use of local versus general anesthesia for inguinal hernia repair. We hypothesized that African American and Hispanic patients would be less likely than Caucasians to receive local anesthesia for inguinal hernia repair., Materials and Methods: We included 78,766 patients aged ≥ 18 years in the Veterans Affairs Surgical Quality Improvement Program database who underwent elective, unilateral, open inguinal hernia repair under general or local anesthesia from 1998-2018. We used multiple logistic regression to compare use of local versus general anesthesia and 30-day postoperative complications by race/ethnicity., Results: In total, 17,892 (23%) patients received local anesthesia. Caucasian patients more frequently received local anesthesia (15,009; 24%), compared to African Americans (2353; 17%) and Hispanics (530; 19%), P < 0.05. After adjusting for covariates, we found that African Americans (OR 0.82, 95% CI 0.77-0.86) and Hispanics (OR 0.77, 95% CI 0.69-0.87) were significantly less likely to have hernia surgery under local anesthesia compared to Caucasians. Additionally, local anesthesia was associated with fewer postoperative complications for African American patients (OR 0.46, 95% CI 0.27-0.77)., Conclusions: Although local anesthesia was associated with enhanced recovery for African American patients, they were less likely to have inguinal hernias repaired under local than Caucasians. Addressing this disparity requires a better understanding of how surgeons, anesthesiologists, and patient-related factors may affect the choice of anesthesia modality for hernia repair., (Copyright © 2021.

Background: Frailty predisposes patients to poor postoperative outcomes. We evaluated whether using local rather than general anesthesia for hernia repair could mitigate effects of frailty., Methods: We used the Risk Analysis Index (RAI) to identify 8,038 frail patients in the 1998-2018 Veterans Affairs Surgical Quality Improvement Program database who underwent elective, open unilateral inguinal hernia repair under local or general anesthesia. Our outcome of interest was the incidence of postoperative complications., Results: In total, 5,188 (65%) patients received general anesthesia and 2,850 (35%) received local. Local anesthesia was associated with a 48% reduction in complications (OR 0.52, 95%CI 0.38-0.72). Among the frailest patients (RAI≥70), predicted probability of a postoperative complication ranged from 22 to 33% with general anesthesia, compared to 13-21% with local., Conclusions: Local anesthesia was associated with a ∼50% reduction in postoperative complications in frail Veterans. Given the paucity of interventions for frail patients, there is an urgent need for a randomized trial comparing effects of anesthesia modality on postoperative complications in this vulnerable population., (Copyright © 2021 Elsevier Inc.

Background: Traditionally, TAVR (Transcatheter Aortic Valve Replacement) has been performed under general anesthesia (GA). Thus GA facilitates the use of TEE (Transesophageal echocardiography), and the use of TEE is an important means to improve the quality of cardiac surgery and reduce postoperative complications. However, GA was also associated with prolonged mechanical ventilation, longer hospitalization and intensive care unit hours, and the need for positive inotropic agents. With increasing clinical experience and advances in transcatheter techniques, transfemoral TAVR may also be feasible under local anesthesia (LA). Studies have shown that LA can avoid hemodynamic fluctuations caused by general anesthesia and lung damage caused by positive pressure ventilation, and can also reduce medical costs., Methods: Two researchers independently read the titles and abstracts of the literature obtained. After excluding the studies that did not meet the inclusion criteria, they read through the full text of the remaining literatures to determine whether they truly met the inclusion criteria. When two researchers disagree on the included literature, the third researcher decides whether to include it or not. For literature with incomplete data, contact the author via email for unpublished data. The included studies were assessed by two researchers for the risk of bias, and cross-checked. Stata16.0 was used for meta-analysis. Heterogeneity was assessed by χ2 test and I2 quantification. Pooled analysis was performed by random effects model. Sensitivity analysis was performed by excluding references one by one. We will perform subgroup analysis based on data conditions., Results: In this study, high quality evidence was provided by selecting local anesthesia and general anesthesia during transfemoral transcatheter aortic valve replacement for patients with primary arterial stenosis., Conclusion: Local anesthesia provides anaesthetic-guided sedation that does not require intubation and is safe and effective. Local anesthesia may be a better alternative to TAVR under general anesthesia., Ethics and Dissemination: The study does not require ethical approval., Inplasy Registration Number: INPLASY202170078., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 the Author(s).

Background: A sialendoscopy-assisted combined approach is well established in the surgery of sialolithiasis. In cases of proximal salivary stones, transcutaneous sialendoscopy-assisted extractions with parotid and submandibular gland preservation is the primary intention of treatment. We recently added computer tomography (CT) navigation to improve the results of this challenging surgery equally in both localizations., Patients and Methods: Al l the patients who submitted to sialendoscopy and sialendoscopy-assisted procedures at the tertiary institution between January 2012 and October 2020 were included in the present study. From November 2019, CT navigation was added in cases with sialolithiasis and a presumably poor sialendoscopic visibility. We evaluated the parameters of the disease, diagnostic procedures, sialendoscopic findings and outcomes, with or without optical surgical navigation., Results: We performed 178 successful salivary stone removals in 372 patients, of which 118 were combined sialendos-copy-assisted approaches, including 16 transcutaneous proximal, 10 submandibular and 6 parotid stone operations. Surgical navigation was used in six patients, four times for submandibular and twice for parotid sialolithiasis. These were all non-palpable, sialendoscopically invisible or partially visible stones, and we managed to preserve five of the six salivary glands., Conclusions: The addition of CT navigation to sialendoscopy-assisted procedures for non-palpable, sialendoscopically invisible and fixed stones is a significant advantage in managing sialolithiasis. By consistently performing sialendoscopy and related preservation procedures, we significantly reduced the need for sialoadenectomies in patients with obstructive salivary gland disease., (© 2021 Aleksandar Anicin, Jure Urbancic, published by Sciendo.)

Aims: Many procedures in ear, nose, and throat (ENT) day surgery are carried out under local anesthesia in Finland, whereas many other countries use general anesthesia. We investigated overstay and readmission rates in local and general anesthesia at Helsinki University Hospital., Material and Methods: We conducted a retrospective study on ENT (n = 1011) day surgery patients within a 3-month period using the hospital's surgery database to collect data pertaining to anesthesia, overstays, readmissions, and contacts within 30 days of surgery., Objectives: We examined the effect of American Society of Anesthesiologists (ASA) class, age, sex, type of procedure, and anesthesia type on overstay, contact, and readmission rates., Results: A multivariable logistic regression model included ASA class, age, sex, type of procedure, and anesthesia (local vs general). Sex, age, and type of procedure had an effect on the outcomes of overstay, readmission, or contact. With general anesthesia, 3.2% (n = 23) had an overstay or readmission compared to 1.4% (n = 4) after local anesthesia. This was mainly explained by the number of study outcomes in tonsillar surgery that was performed only in general anesthesia., Conclusions: Day surgery could be done safely using local anesthesia, as the number of study outcomes was no greater than in general anesthesia. Sex, type of procedure, and age affected the rate of study outcomes, but ASA class and anesthesia form did not. Our overstay, contact, and readmission rates are on the same level, or lower, than in international studies.

Background: This study investigates the associations between local anesthesia practice and perioperative complication, length of stay, and hospital cost for palatoplasty in the United States., Methods: Patients undergoing cleft palate repair between 2004 and 2015 were abstracted from the Pediatric Health Information System database. Perioperative complication, length of stay, and hospital cost were compared by local anesthesia status. Multiple logistic regressions controlled for patient demographics, comorbidities, and hospital characteristics., Results: Of 17,888 patients from 49 institutions who met selection criteria, 8631 (48 percent), 4447 (25 percent), and 2149 (12 percent) received epinephrine-containing lidocaine, epinephrine-containing bupivacaine, and bupivacaine or ropivacaine alone, respectively. The use of epinephrine-containing bupivacaine or bupivacaine or ropivacaine alone was associated with decreased perioperative complication [adjusted OR, 0.75 (95 percent CI, 0.61 to 0.91) and 0.63 (95 percent CI, 0.47 to 0.83); p = 0.004 and p = 0.001, respectively]. Only bupivacaine- or ropivacaine-alone recipients experienced a significantly reduced risk of prolonged length of stay on adjusted analysis [adjusted OR, 0.71 (95 percent CI, 0.55 to 0.90); p = 0.005]. Risk of increased cost was reduced in users of any local anesthetic (p < 0.001 for all)., Conclusions: Epinephrine-containing bupivacaine or bupivacaine or ropivacaine alone was associated with reduced perioperative complication following palatoplasty, while only the latter predicted a decreased postoperative length of stay. Uses of epinephrine-containing lidocaine, epinephrine-containing bupivacaine, and bupivacaine or ropivacaine alone were all associated with decreased hospital costs. Future prospective studies are warranted to further delineate the role of local anesthesia in palatal surgery., Clinical Question/level of Evidence: Therapeutic, III., (Copyright © 2021 by the American Society of Plastic Surgeons.)

Background: Percutaneous magnetic resonance-guided (MR-guided) MWA procedures have traditionally been performed under local anesthesia (LA) and sedation. However, pain control is often difficult to manage, especially in some cases when the tumor is large or in a specific location, such as near the abdominal wall or close to the hepatic dome. This study retrospectively compared the results of general anesthesia (GA) and local anesthesia (LA) for MR-guided microwave ablation (MWA) in patients with hepatocellular carcinoma (HCC ≤ 5.0 cm) to investigate whether different anesthesia methods lead to different clinical outcomes., Methods: The results of the analysis include procedure-related complications, imaging response, and the time to complete two sets of procedures. According to the type of anesthesia, the Kaplan-Meier method was used to compare the local tumor progression (LTP) of the two groups who underwent MR-guided MWA., Results: All patients achieved technical success. The mean ablation duration of each patient in the GA group and LA group was remarkably different (P = 0.012). Both groups had no difference in complications or LTP (both P > 0.05). Notably, the tumor location (challenging locations) and the number of lesions (2-3 lesions) could be the main factors affecting LTP (p = 0.000, p = 0.015). Univariate Cox proportional hazard regression indicated that using different anesthesia methods (GA and LA) was not associated with longer LTP (P = 0.237), while tumor location (challenging locations) and the number of lesions (2-3 lesions) were both related to shorter LTP (P = 0.000, P = 0.020, respectively). Additionally, multivariate Cox regression further revealed that the tumor location (regular locations) and the number of lesions (single) could independently predict better LTP (P = 0.000, P = 0.005, respectively)., Conclusions: No correlation was observed between GA and LA for LTP after MR-guided MWA. However, tumors in challenging locations and the number of lesions (2-3 lesions) appear to be the main factors affecting LTP.

Background: Inguinal hernia surgery is a frequent procedure among general surgeons in Costa Rica, but the management and technique are not uniform. The International Guideline for Groin Hernia management was published in 2018 to standardize the inguinal hernia surgery, but the diffusion of the guidelines and its adherence have been extremely varied., Purpose: Collect and analyze the current reality regarding groin hernia management in Costa Rica. Secondly evaluate the diffusion and development comparing it to the guideline's recommendations., Method: Questionnaire of 42 single and multiple answer questions according to the topics of the International Guideline directed to general surgeons. Diffusion of the inquiry through surgical and hernia association chats and email. Timeframe June-December 2019., Results: 64 surveys were collected, which is a representative number of the general surgeons national college. The most frequent procedure between these was the abdominal wall surgery. Every surgeon did more than 52 groin hernia surgeries in one year, most of them outpatients. The epidural anesthesia was used the most and Lichtenstein's technique was the most frequently used (64%). 68% of the surgeons know how to perform a minimally invasive inguinal hernia surgery but with variable volumes. 38% of participants considered themselves experts in groin hernia management and 52% did not know the 2018 International Guideline. The recommendations of such guideline are followed only partially., Conclusions: The 2018 Hernia Surge International Guidelines have low diffusion among Costa Rican surgeons. The laparoscopic approach is widely accepted but there are no studies to assess the results and the quality. There should be protocols and studies adapted to Costa Rica's national situation.

Background: Inguinal hernia repair is the most common general surgery operation in the United States. Nearly 80% of inguinal hernia operations are performed under general anesthesia versus 15%-20% using local anesthesia, despite the absence of evidence for the superiority of the former. Although patients aged 65 y and older are expected to benefit from avoiding general anesthesia, this presumed benefit has not been adequately studied. We hypothesized that the benefits of local over general anesthesia for inguinal hernia repair would increase with age., Materials and Methods: We analyzed 87,794 patients in the American College of Surgeons National Surgical Quality Improvement Project who had elective inguinal hernia repair under local or general anesthesia from 2014 to 2018, and we used propensity scores to adjust for known confounding. We compared postoperative complications, 30-day readmissions, and operative time for patients aged <55 y, 55-64 y, 65-74 y, and ≥75 y., Results: Using local rather than general anesthesia was associated with a 0.6% reduction in postoperative complications in patients aged 75+ y (95% CI -0.11 to -1.13) but not in younger patients. Local anesthesia was associated with faster operative time (2.5 min - 4.7 min) in patients <75 y but not in patients aged 75+ y. Readmissions did not differ by anesthesia modality in any age group. Projected national cost savings for greater use of local anesthesia ranged from $9 million to $45 million annually., Conclusions: Surgeons should strongly consider using local anesthesia for inguinal hernia repair in older patients and in younger patients because it is associated with significantly reduced complications and substantial cost savings., (Copyright © 2020 Elsevier Inc.

Background: Surgery for anorectal disease is thought to cause significant postoperative pain. Our previous work demonstrated that most opioids prescribed after anorectal surgery are not used. We aimed to evaluate a standardized protocol for pain control after anorectal surgery., Methods: We prospectively evaluated a standardized opioid reduction protocol over a 13-mo period for all patients undergoing elective anorectal surgery at our institution. Protocol components include preoperative query, procedural local-anesthetic blocks, first-line nonopioid analgesic use ± opioid prescription of five pills, and standardized postoperative instructions. Patients completed questionnaires at postoperative follow-up. Patients with history of opioid abuse or use within 30 d of operation, loss to follow-up, or surgical complications were excluded. Primary outcome was quality of pain control on a five-point scale. Secondary outcomes included use of nonopioid analgesics, opioids used, and need for refill., Results: A total of 55 patients were included. Mean age was 47 ± 17 y with 23 women (42%). Anorectal abscess/fistula procedures were the most common (69%) followed by pilonidal procedures (11%) and hemorrhoidectomy (7%). Most had general anesthesia (60%) with the remainder local anesthesia ± sedation. Fifty-four (98%) had procedural local-anesthetic blocks. Twenty-six patients (47%) were prescribed opioids with a median of five pills. Forty-seven patients (85%) reported the use of nonopioid analgesics. Forty-six patients (84%) reported excellent to very good pain control. About 220 opioid pills were prescribed, and 122 were reported to be used. One patient (2%) received an opioid refill., Conclusions: Satisfactory pain control after anorectal surgery can be achieved with multimodality therapy with little to no opioid use for most patients., (Copyright © 2020 Elsevier Inc.

Background: Wound infiltration analgesia provides effective postoperative pain control in patients undergoing laparoscopic cholecystectomy (LC). However, the efficacy and safety of wound infiltration with different doses of ropivacaine is not well defined. This study investigated the analgesic effects and pharmacokinetic profile of varying concentrations of ropivacaine at port sites under laparoscopy assistance., Methods: In this randomized, double-blinded study, 132 patients were assigned to 4 groups: Group H: in which patients were infiltrated with 0.75% ropivacaine; Group M: 0.5% ropivacaine; Group L: 0.2% ropivacaine; and Group C: 0.9% normal saline only. The primary outcome was pain intensity estimated using numeric rating scale (NRS) at discharging from PACU and at 4 hours, 6 hours, 8 hours, and 24 hours after infiltration. Secondary outcomes included plasma concentrations of ropivacaine at 30 minutes after wound infiltration, rescue analgesia requirements after surgery, perioperative vital signs changes, and side effects., Results: The NRS in Group C was significantly higher at rest, and when coughing upon leaving PACU and at 4 hours, 6 hours, 8 hours, and 24 hours after infiltration (P < .05) and rescue analgesic consumption was significantly higher. Notably, these parameters were not significantly different between Groups H, Group M and Group L (P > .05). Intra-operative consumption of sevoflurane and remifentanil, HR at skin incision and MAP at skin incision, as well as 5 minutes after skin incision were significantly higher in Group C than in the other 3 groups (P < .01). In contrast, these parameters were not significantly different between Groups H, Group M and Group L (P > .05). The concentration of ropivacaine at 30 minutes after infiltration in Group H was significantly higher than that of Group L and Group M (P < .05). No significant differences were observed in the occurrence of side effects among the 4 groups (P > .05)., Conclusions: Laparoscopy-assisted wound infiltration with ropivacaine successfully decreases pain intensity in patients undergoing LC regardless of the doses used. Infiltration with higher doses results in higher plasma concentrations, but below the systematic toxicity threshold.

Background: Local anesthesia (LA) for open inguinal hernia repair (OIHR) is not widely used in the United States. An LA program for OIHR was initiated at the Dallas Veteran Affairs Medical Center in 2015. We hypothesize that outcomes under LA for OIHR are similar to general anesthesia with adequate patient satisfaction., Methods: A total of 1422 groin hernias were performed by a single surgeon using a standardized technique at the Dallas Veteran Affairs Medical Center (2015-2019). Only unilateral, primary, elective, OIHRs were included (n = 1092). LA was used in 26.0% (n = 285) and compared with patients undergoing general anesthesia. Univariate analysis was performed by the Student t-test for continuous variables and χ 2 test (or the Fisher exact test) for categorical variables., Results: OIHR performed with LA increased from 15.5% in 2015 to 76.6% in 2019. Patients undergoing LA were older and had significantly more comorbidities. Holding time to operating room (OR), OR to start of the operation, skin-to-skin time, and end of the operation to out of the OR were all reduced with LA (all P values <0.05). Inguinodynia, recurrence, and overall complications were similar. Patients undergoing LA indicated that they were comfortable (93.0%), rated their worst pain as 2.03 ± 2.2 (of 10), and would undergo LA if they had to do it again (94.0%)., Conclusions: LA was associated with decreased OR times and had good patient satisfaction. Overall complication rates were similar despite a higher burden of comorbid conditions in patients undergoing LA., (Published by Elsevier Inc.)

We conducted a survey and semi-structured qualitative interviews to investigate current anaesthetic practice for arteriovenous fistula formation surgery in the UK. Responses were received from 39 out of 59 vascular centres where arteriovenous access surgery is performed, a response rate of 66%. Thirty-five centres reported routine use of brachial plexus blocks, but variation in anaesthetic skill-mix and practice were observed. Interviews were conducted with 19 clinicians from 10 NHS Trusts including anaesthetists, vascular access and renal nurses, surgeons and nephrologists. Thematic analysis identified five key findings: (1) current anaesthetic practice showed that centres could be classified as 'regional anaesthesia dominant' or 'local anaesthesia/mixed'; (2) decision making around mode of anaesthesia highlighted the key role of surgeons as frontline decision makers across both centre types; (3) perceived barriers and facilitators of regional block use included clinicians' beliefs and preferences, resource considerations and patients' treatment preferences; (4) anaesthetists' preference for supraclavicular blocks emerged, alongside acknowledgement of varied practice; (5) there was widespread support for a future randomised controlled trial, although clinician equipoise issues and logistical/resource-related concerns were viewed as potential challenges. The use of regional anaesthesia for arteriovenous fistula formation in the UK is varied and influenced by a multitude of factors. Despite the availability of anaesthetists capable of performing regional blocks, there are other limiting factors that influence the routine use of this technique. The study also highlighted the perceived need for a large multicentre, randomised controlled trial to provide an evidence base to inform current practice., (© 2020 The Authors.

Aims: The aim of this study is to compare the efficacy and safety of percutaneous radiofrequency ablation (RFA) under general anesthesia or local anesthesia plus intraoperative analgesia in the treatment of hepatocellular carcinoma (HCC) at unusual regions., Subjects and Methods: From July 2012 to October 2019, 83 consecutive patients with 107 HCC lesions were treated with interventional radiology therapy. The lesions were located at some unusual regions such as diaphragmatic surface, hepatic hilum, hepatic subcapsular region, tissues near inferior vena cava, and tissues near the colon. General anesthesia was applied in 57 cases (general anesthesia group) and local anesthesia plus intraoperative analgesia was used in 26 cases (local anesthesia group). All patients were treated with transcatheter arterial chemoembolization, followed immediately by RFA. The rate of tumor inactivation, time used for placing RF needles to the scheduled sites, pain score, and complications were analyzed., Statistical Analysis Used: All continuous variables were tested for the normal/nonnormal distribution by Kolmogorov-Smirnov test. The t-test was used to analyze the normal distribution variables; the Mann-Whitney U-test was used to measure nonnormal distribution variables; and the Chi-square test for categorical variables. P < 0.05 was considered statistically significant., Results: The treatments were successful in all patients, including 51 cases of complete response (CR) and 6 cases of partial response (PR) in the general anesthesia group and 18 cases of CR and 8 cases of PR in the local anesthesia group (P = 0.049). The time used for placing the needles to the scheduled sites was 1-5 min (mean 2 min) in the general anesthesia group and 2-9 min (mean 4 min) in the local analgesia group (P < 0.001). The pain scores ranged from 0 to 2 points (mean 1 point) in the general anesthesia group and 2-9 points (mean 5 points) in the local anesthesia group (P < 0.001). With regard to complications, seven cases had pneumothorax and four cases had slight hepatic subcapsular hemorrhage in the general anesthesia group and four cases of pneumothorax and three cases of slight hepatic subcapsular hemorrhage in the local anesthesia group, and the difference was not statistically significant between the two groups (P = 0.715)., Conclusions: For HCC located at unusual regions, general anesthesia is superior to local anesthesia plus intraoperative analgesia in percutaneous RFA in reducing the difficulty of the procedure and improving the safety of RFA., Competing Interests: None

Background: Carpal tunnel syndrome is a common cause of upper extremity discomfort. Surgical release of the median nerve can be performed under general or local anesthetic, with or without a tourniquet. Wide-awake carpal tunnel release (CTR) (local anesthesia, no sedation) is gaining popularity. Tourniquet discomfort is a reported downside. This study reviews outcomes in wide-awake CTR and compares tourniquet versus no tourniquet use. Methods: Wide-awake, open CTRs performed from February 2013 to April 2016 were retrospectively reviewed. Patients were divided into 2 cohorts: with and without tourniquet. Demographics, comorbidities, tobacco use, operative time, estimated blood loss, complications and outcomes were compared. Results: A total of 304 CTRs were performed on 246 patients. The majority of patients were male (88.5%), and the mean age was 59.9 years. One hundred patients (32.9%) were diabetic, and 92 patients (30.2%) were taking antithrombotics. Seventy-five patients (24.7%) were smokers. A forearm tourniquet was used for 90 CTRs (29.6%). Mean operative time was 24.97 minutes with a tourniquet and 21.69 minutes without. Estimated blood loss was 3.16 mL with a tourniquet and 4.25 mL without. All other analyzed outcomes were not statistically significant. Conclusion: Operative time was statistically longer and estimated blood loss was statistically less with tourniquet use, but these findings are not clinically significant. This suggests that local anesthetic with epinephrine is a safe and effective alternative to tourniquet use in CTR. The overall rate of complications was low, and there were no major differences in postoperative outcomes between groups.

Purpose: The aim of this study was to survey the frequency of various anesthetic techniques used in the anesthetic management of both the mother and fetus during fetal therapies in Japan., Methods: We sent a postal survey to the institutions with physicians who held membership of the Japan Society of Fetal Therapy to describe maternal and fetal anesthetic management during fetal therapies performed from January 2016 to March 2017. The therapies included were thoracoamniotic shunting (TAS), intrauterine transfusion (IUT), radiofrequency ablation (RFA), fetoscopic laser photocoagulation (FLP), fetoscopic endotracheal occlusion (FETO), and ex utero intrapartum treatment (EXIT). Survey respondents were asked to specify the standard anesthetic technique used in each of these procedures done during the study period., Results: The most common anesthetic techniques used in each therapy were sedation/analgesia with local anesthesia in TAS (31%), local anesthesia alone in IUT (47%), neuraxial anesthesia in RFA (50%), FLP (66%) and FETO (100%), and general endotracheal anesthesia in EXIT. Fetal analgesia was utilized in 61% of TAS, 33% of IUT, 10% of RFA, 22% of FLP, 100% of FETO, and 50% of EXIT. In all fetal therapies, the most common route of administration for fetal anesthesia was maternal administration., Conclusion: In this first published description of the frequency of various anesthetic techniques used during fetal therapies in Japan, we found that anesthetic techniques varied depending on the degree of invasiveness to the mother and fetus. Fetal anesthesia was not always performed, and the most common route for fetal anesthesia was maternal administration.

Background: Recently, the European prospective observational multicenter cohort study, APRICOT, reported anesthesia techniques and complications in more than 31 000 pediatric procedures. The main objective of this study was to analyze the current practice in regional anesthesia in the 33 countries that participated to APRICOT., Methods: Data on regional anesthesia techniques were extracted from the database of APRICOT (261 centers across 33 European countries). All children, aged from birth to 16 years old, were eligible for inclusion during a 2-week period. Type of regional anesthesia, whether used awake or with sedation or general anesthesia, techniques of guidance, and the drugs administered were analyzed., Results: Regional anesthesia was used in 4377 pediatric surgical procedures. The large majority was performed under general anesthesia with central blocks and truncal blocks, representing, respectively, 42.6% and 41.8% of performed techniques. Caudal blocks represented 76.9% of all central blocks. The penile and ilioinguinal/iliohypogastric blocks were the most commonly performed truncal blocks. Anesthetists used mainly anatomical landmarks; ultrasound guidance was applied in only 23.8% of cases. A wide variability of practices was observed in terms of regional anesthesia techniques and local anesthetics among the participating European countries. No serious complications were reported., Conclusion: These data show a large predominance of central and truncal blocks in APRICOT study. Ultrasound guidance was mainly used for peripheral nerve blocks while central blocks were performed using landmark techniques., (© 2019 John Wiley & Sons Ltd.)

Background: The upper limb surgery under the ultrasound-guided brachial plexus block is becoming popular due to its safety, effectiveness, and convenience. However, the uneven distribution of anesthesiologists become a social problem. Ultrasound-guided brachial plexus block by surgeons has been widespread especially in hand surgeons. We report the surgical treatment of distal radius fractures under the ultrasound-guided brachial plexus block performed by surgeons in our hospital. Methods: The subjects were 101 patients (41 males and 60 females, average age 61.6 years) who underwent surgery for distal radius fractures under ultrasound-guided brachial plexus block administered by orthopedists at our university or related facilities between January 2014 and June 2016. Brachial plexus block was administered through the supraclavicular approach. The time from initiation of anesthesia to initiation of surgery, mean operative time, the presence or absence of additional anesthesia (local infiltration anesthesia, intravenous anesthesia, and general anesthesia), and complications were evaluated. Results: The mean time from brachial plexus block to initiation of surgery was 35.7 (20-68) minutes, and the mean operative time was 90.5 (35-217) minutes. Surgery was completed with brachial plexus block alone in 62 patients (61.4%), and additional anesthesia was necessary in 39 patients (38.6%). Furthermore, general anesthesia was employed in 6 patients (5.9%). No serious complications occurred. Conclusions: According to our results, the operation could be completed with brachial plexus block alone and additional local infiltration anesthesia or intravenous anesthesia in 94.1% (95 cases). However, 6 cases (5.9%) shifted to general anesthesia. Although it needs training, we consider that hand surgery including distal radius fractures treatment under the ultrasound-guided brachial plexus block is possible. On the other hand, cooperation or a cooperative system with anesthesiologists is necessary for surgeons to administer this anesthesia.

Introduction: Transcatheter aortic valve implantation is a less invasive option for aortic valve replacement. The number of transcatheter aortic valve implantations under local anesthesia with sedation has been increasing as the team's experience increases and less invasive accesses are used. The aim of this study is to describe the evolution of the anesthetic technique in patients undergoing transcatheter aortic valve implantation at our center over the years, as which was compared., Material and Methods: Retrospective study in 149 consecutive patients undergoing transcatheter aortic valve implantation in Hospital Santa Marta (January 2010 to December 2016). Data was collected from the periprocedural records of patients. Patients were stratified according to anesthetic technique., Results: From our patients' sample, 57.0% were female, with median age 82 [58 - 95] years. Most patients underwent general anesthesia (68.5%). In the local anesthesia with sedation group there was a shorter duration of the procedure (120; [60 - 285] vs 155 [30 - 360]) and a lower number of patients requiring administration of vasopressors (61.8% vs 28.3%) - p < 0.05. There were no differences regarding length of hospital stay (9 [4 - 59] vs 10 [3 - 87]), periprocedural complications (66.0% vs 72.5%), readmission rate (4.3% vs 3.9%) or 30-days (2.1% vs 4.9%) and 1-year mortality (6.4% vs 7.8%) - p < 0.05. There was an increasing number of transcatheter aortic valve implantations performed under local anesthesia with sedation over the years., Discussion: The choice of anesthetic technique depends on the patient's characteristics, experience and preference of the team., Conclusion: Local anesthesia with sedation seems to be associated with similar results as general anesthesia. The increase in the number of transcatheter aortic valve implantations under local anesthesia with sedation seems to follow the trend of lower invasiveness of the procedure.

Chronic pain and recurrence rates are the main challenge in modern inguinal hernia surgery. Several trials have investigated the role of self-adhesive mesh repair for inguinal hernia, with special attention to the incidence of chronic postoperative inguinal pain and recurrence. The purpose of our study was to retrospectively evaluate the early and long-term results using a self-gripping mesh (Parietex Progrip® , Covidien) in our institution. A total of 204 patients, mean age 50.3 standard deviation (SD) 15.3, was included in the study. The repair was performed under local anaesthesia in 159 (78%) cases and locoregional anaesthesia in remaining 45 (22%). Mean operative time was 39 ± 20 minutes. The time for self-gripping mesh placement ranged from 5 to 9 minutes (mean 7 ± 2 minutes). There were no intraoperative complications. Clinical follow-up was performed at 1 month, 1 year and 2 years and consisted in the evaluation of complications, discomfort/pain and recurrence. One case of cutaneous infection and three cases of seroma were observed at one-month follow-up and were all treated conservatively. 8 patients were lost at one year follow-up, and another 4 were lost at 2 years. 3 patients died for other causes during follow-up. At 1 year and 2 years follow-up no cases of seroma, testicular complications or mesh infection were observed. Two cases of recurrence were recorded at 2 years follow up. No patient reported VAS score > 2 at one month, 1 year and 2 years follow-up. There were no readmissions, systemic complications or death during 2 years follow-up. Lichtenstein open repair using Parietex Progrip® mesh is a simple, rapid, effective and safe method for inguinal hernia repair. The main advantage of self-fixing mesh is the reduced operative time. A suturless fixation seems to prevent the development of postoperative chronic pain, without increasing recurrence rate in the majority of the trials.

Introduction: Inguinal hernia repair is a common procedure and a priority for public health efforts in Ghana. It is essential that inguinal hernia repair be performed in a safe, efficient manner to justify its widespread use. Local anesthesia has many favorable properties and has been shown to be superior, compared to regional or general anesthesia, in terms of pain control, safety profile, cost-effectiveness, resources required, and time to discharge. Local anesthesia is recommended for open repair of reducible hernias, provided clinician experience, by multiple international guidelines. Regional anesthesia is associated with myocardial infarction and other complications, and its use is discouraged by multiple guidelines, especially in older patients. This study aims to assess the current state of anesthesia for inguinal hernia repair in the northern and transitional zone of Ghana. In addition we will assess the perceptions of different types of anesthesia along with understanding of evidence-based guidelines among clinicians participating in inguinal hernia repair., Methods: We performed a retrospective review of all inguinal hernia repairs for male patients, 18 and older, in over 90% of hospitals in northern Ghana. All 41 hospitals were visited and caselogs and patient charts were manually reviewed to extract data. Multivariate logistic regression was used to determine predictors of local anesthesia use. We designed a survey instrument to assess the perceptions of physicians and anesthetists regarding different types of anesthesia for inguinal hernia repair. The survey was designed by a Ghanaian surgeon, reviewed by all co-authors, and tested prior to implementation using a sample (n = 8) of clinicians having similar practices to those of the survey population. Of 70 clinicians, 66 responded, yielding a response rate of 94%., Results: 8080 patients underwent hernia repair of which 37% were performed under local anesthesia, while the majority, 60%, were performed under regional anesthesia. Negative predictors of local anesthesia were emergent repair (OR = 0.258, p < 0.001), surgery performed at a teaching hospital (OR = 0.105, p < 0.001), and bilateral hernia repair (OR = 0.374, p < 0.001). 1,839 (22.8%) of IH repairs were done on patients age 65 or older and RA was most frequently used among the elderly population (57.8%), while local anesthesia was used 39.5% of the time. Sixty-six clinicians participated in the survey with the majority reporting that local anesthesia requires fewer staff, less equipment, has a shorter recovery, is more cost-effective, and might be safer for patients. However 66% were unfamiliar with or incorrectly perceived international guidelines., Conclusion: To our knowledge, this study is the largest assessment of anesthesia use for inguinal hernia repair in an LMIC. Although the selection of anesthetic technique should be guided by a patient's general health, the anatomy of the hernia, and clinician judgment, local anesthesia appears to be underutilized in northern Ghana. Survey responses demonstrate high rates of unfamiliarity or incorrectly perceived evidence-based guidelines. Future research should assess how education on the benefits and technique of local anesthesia administration may further increase rates for inguinal hernia repair, especially for older patients., Competing Interests: The authors have declared that no competing interests exist.

Background: An electronic review of unplanned day case admission rates in our hospital demonstrated an average annual rate for pediatric circumcision of 2%-3% in recent years with high levels of perioperative strong opiate use. This lay above target unplanned admission rates (<2%) set out by the Royal College of Anaesthetists for day case surgery. A targeted quality improvement initiative was undertaken to improve patient flow through the pediatric day case surgery unit for elective circumcision. Among the reasons for unplanned admission, factors modifiable by the anesthetist (pain, postoperative nausea and vomiting, somnolence) are significant contributors., Methods: A prospective audit was undertaken over a 3-month period. Our practice was compared with evidence-based analgesic and antiemetic interventions in accordance the Association of Paediatric Anaesthetists of Great Britain and Ireland. Perioperative strong opiate administration rates occurred in 44% of cases. Four strategic interventions were selected based on quality of evidence, ease of implementation, and low cost: selection of higher concentration local anesthetic use for penile blocks, intravenous dexamethasone, and preoperative paracetamol combined with maximum dose nonsteroidal anti-inflammatory., Results: The audit was duplicated a year later demonstrating a significant increase in application of these interventions with a parallel fall in strong opiate use from 44% to 9% and an unprecedented zero unplanned admission rate in our unit for 10 months in a row after implementation., Conclusion: Regular scrutiny of patient electronic data helps identify high impact areas for audit and intervention. Unplanned admission in pediatric day case surgery is an area amenable to such targeted intervention., (© 2018 John Wiley & Sons Ltd.)

Background: Septal surgery is a well-established procedure used to treat nasal obstruction due to deviation of the nasal septum, which is carried out under local or general anaesthesia. Local anaesthesia is used for postoperative pain control, but its effectiveness and safety are unclear., Objectives: To assess the effectiveness of perioperative local anaesthesia for reducing pain in septal surgery and to evaluate the risk of associated complications., Search Methods: The Cochrane ENT Information Specialist searched the Cochrane ENT Trial Register; Central Register of Controlled Trials; Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 9 January 2018., Selection Criteria: Randomised controlled trials and cluster-randomised controlled trials involving adults or children (or both) who underwent septal surgery. We included studies comparing local anaesthesia versus no treatment/placebo. We also included studies comparing different types of local anaesthesia to each other (i.e. local injection, the addition of an anaesthetic agent to nasal packing, where used, and sphenopalatine ganglion block)., Data Collection and Analysis: We used the standard methodological procedures expected by Cochrane. The primary outcome was postoperative pain intensity at 12, 24 and 48 hours measured by visual analogue scale (VAS) or another pain outcome tool including numerical or verbal rating scales. Secondary outcomes were requirement for additional analgesia, duration of hospitalisation and adverse effects (postoperative bleeding and postoperative vomiting). We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics., Main Results: We included seven randomised controlled trials involving 493 participants. In all studies the participants were adults undergoing septoplasty. These studies were heterogeneous and the quality of the body of evidence ranged from low to very low. Few of the studies provided reliable data for the primary outcome in this review.Local anaesthetic injection versus no treatment/placeboTwo studies (142 participants) compared local anaesthetic injection versus placebo but these studies did not report postoperative pain at 12, 24 or 48 hours. It is unclear whether local anaesthetic injection changed the risk of vomiting (odds ratio (OR) 3.10, 95% confidence interval (CI) 0.12 to 79.23; 60 participants; one study) (low-quality evidence). Neither study reported the requirement for additional analgesia, duration of hospitalisation or uncontrollable postoperative bleeding.Local anaesthetic application via nasal packing versus no packing/packing with placeboFour studies (301 participants) used nasal packing postoperatively and compared the addition of local anaesthetic to the pack versus packing with a placebo added. Compared with packing with placebo, the addition of local anaesthetic to nasal packing reduced the pain score on a VAS (ranging from 0 to 100) at 12 hours (mean difference (MD) -16.95, 95% CI -22.27 to -11.62; 151 participants; two studies; I 2 = 49%) (low-quality evidence) and at 24 hours postoperatively (MD -7.53, 95% CI -9.76 to -5.29; 268 participants; four studies; I 2 = 83%) (very low-quality evidence). These studies did not report postoperative pain at 48 hours. The addition of local anaesthetic to nasal packing decreased the requirement for additional analgesia (OR 0.15, 95% CI 0.07 to 0.34; 151 participants; two studies; I 2 = 15%) (moderate-quality evidence). No studies reported duration of hospitalisation, postoperative vomiting or uncontrollable postoperative bleeding.No studies compared the addition of local anaesthetic to nasal packing versus no packing.Sphenopalatine ganglion block versus no treatment/placeboOne study (50 participants) compared sphenopalatine ganglion block versus no treatment but this study did not report postoperative pain, requirement for additional analgesia, duration of hospitalisation, vomiting or uncontrollable postoperative bleeding., Authors' Conclusions: The addition of local anaesthesia to nasal packs (if these are being used) following septal surgery may reduce postoperative pain within the first 12 hours, compared to nasal packing with a placebo added. The effect is uncertain at 24 hours because the quality of the evidence is very low. Evidence was lacking for other outcomes, including adverse effects. There is a lack of evidence about the effects of local anaesthesia added to nasal packing compared to no nasal packing. There is also a lack of evidence about the effects of local anaesthesia given by injection and the effects of sphenopalatine ganglion block.

Background: The psoas compartment block (PCB) or periarticular soft-tissue local anesthetic injection are forms of regional anesthesia often used as one of the components in multimodal anesthesia applied during total hip arthroplasty (THA). The most efficacious form of regional anesthesia for THA has yet to be determined., Methods: In a single-surgeon, prospective, clinical trial, patients undergoing THA via direct anterior approach were randomized to receive an intraoperative periarticular local anesthetic infiltration (periarticular injection) or a PCB. Postoperative pain scores, narcotic consumption, and complications were recorded., Results: Forty-nine patients were randomized to the PCB and 50 were randomized to the periarticular injection. The resting pain score 3 hours postoperatively was statistically significantly lower in the periarticular injection group by 1.1 point (2.9 ± 2.2 vs 4.0 ± 2.2, P = .036). No difference was found in resting pain scores or ambulatory pain scores in the morning or evening of postoperative day 1, 2, or at the 3-week follow-up visit. There was no difference in in-hospital narcotic consumption between groups (P = 1.0). There were no major complications directly related to the block in either group. A total of 6 patients reported complaints of transient numbness, 5 in the PCB group (5/49, 10.2%), and one in the periarticular injection group (1/50, 2%, P = .087)., Conclusion: These results demonstrate similarity between the 2 methods. We prefer periarticular anesthetic infiltration over PCB due to improved immediate postoperative pain scores and avoidance of potential symptoms associated with nerve blockade., (Copyright © 2018 Elsevier Inc.

Cell therapy based on the trophic, mitogenic, and immunomodulatory capacity of mesenchymal stem cells is a promising treatment modality for degenerative musculoskeletal conditions. Local anesthetics have been commonly used in interventional procedures for alleviating pain, but local anesthetics may have negative impact on MSC dosing because of cytotoxicity or other biological effects. Because previous studies have not reached consensus yet on the potential complications of local anesthetics in cell therapy, we reviewed 11 studies that involve in vitro experimentation with MSCs using aminoamide-type anesthetics including lidocaine, ropivacaine, mepivacaine, bupivacaine, articaine, and prilocaine. Three studies that compare the effects of different types of local anesthetic agents showed that ropivacaine has the least detrimental effects on mesenchymal stem cell populations, whereas lidocaine seems to have the most significant effects on stem cell viability. Concentration- and time-dependent effects on cell viability were reported with bupivacaine, ropivacaine, lidocaine, and mepivacaine. We conclude that local anesthetic agents have time- and concentration-dependent detrimental effects on MSCs. However, in vivo studies will be required to understand the interactions of these agents with MSCs, because in vitro studies cannot replicate the pharmacokinetics of anesthetics in vivo or the recovery of MSCs in a more physiological environment.

Background: Cold therapy used in the sports medicine settings has been found to be effective in reducing postoperative pain; however, there are limited studies that examine the effect of cold therapy on postoperative pain in patients with posterior lumbar spinal fusion., Purpose: The purpose of this study was to determine the effects of cold on postoperative spine pain and add to the body of knowledge specific to practical application of cold therapy in the spine surgery setting., Methods: Researchers used a two-group randomized control design to evaluate the effects of local cold therapy on postoperative pain and analgesia use after lumbar spinal fusion surgery. The primary outcome was postoperative pain. Secondary outcomes included analgesia use and perceived benefit of cold therapy., Results: The intervention (cold) group had a marginally greater reduction in mean Numerical Rating Scale score across all 12 pain checks (M ± SD = -1.1 ± 0.8 points reduction vs. -1.0 ± 0.8 points reduction, p = .589). On average, the intervention group used less morphine equivalents (M ± SD = 12.6 ± 31.5 vs. 23.7 ± 40.0) than the control group across pain checks seven to 12 (p = .042)., Conclusions: This study provides additional evidence to support the use of cold therapy as an adjuvant pain management strategy to optimize pain control and reduce opioid consumption following spine fusion surgical procedures.

Background: Although femoral nerve block provides satisfactory analgesia after total knee arthroplasty (TKA), residual posterior knee pain may decrease patient satisfaction. We conducted a randomized controlled trial to clarify the efficacy of the sciatic nerve block (SNB) and local infiltration of analgesia with steroid (LIA) regarding postoperative analgesia after TKA, when administrated in addition to femoral nerve block (FNB)., Methods: Seventy-eight patients were randomly allocated to the two groups: concomitant administration of FNB and SNB or FNB and LIA. The outcome measures included post-operative pain, passive knee motion, C-reactive protein level, time to achieve rehabilitation goals, the Knee Society Score at the time of discharge, patient satisfaction level with anesthesia, length of hospital stay, surgical time, and complications related to local anesthesia., Results: The patients in group SNB showed less pain than group LIA only on postoperative hours 0 and 3. Satisfactory postoperative analgesia after TKA was also achieved with LIA combined with FNB, while averting the risks associated with SNB. The influence on progress of rehabilitation and length of hospital stay was similar for both anesthesia techniques., Conclusions: The LIA offers a potentially safer alternative to SNB as an adjunct to FNB, particularly for patients who have risk factors for sciatic nerve injury.

Background: Nowadays the prognostic role of gender as a relevant factor after transcatheter aortic valve implantation (TAVI) is still unfair, since available data in the literature are few and uneven. The aim of this survey was to collect acute and 30-day safety and efficacy clinical data in high- and intermediate-risk women, who underwent TAVI with new-generation devices, in the Campania Region., Methods: All medium and high-volume TAVI centers in Campania have been invited to fulfill an online, ad-hoc questionnaire, collecting pre-, peri- and post-procedural data concerning female patients, treated between January and December 2016., Results: 331 women (representing the 61% of the overall population treated; mean age 83 ± 7 years) underwent TAVI in the participating Campania centers. Age >80 years (72%), high surgical risk score (63%) and frailty (55%) were found to be the top three reasons for the TAVI choice. Overall, 95% of the procedures were performed by transfemoral approach with local anesthesia; the remaining 5% (16 cases) were conducted via transapical (14, 4%) and transaortic (2, 1%) accesses, under general anesthesia. Edwards Sapien 3 (Edwards Lifesciences, Irvine, CA, USA) and Medtronic Evolut R (Medtronic Inc., Minneapolis, MN, USA) were the most frequently implanted valves (146, 44% and 132, 43%, respectively). The questioned Centers reported a mean length of hospital stay of 5.5 ± 1.1 days, 1.6 ± 0.37 of which in a cardiac care unit. The most prevalent in-hospital complication was pacemaker implantation (15%), followed by life-threatening vascular complications (3%). The 30-day VARC-2 composite endpoint occurred in 7% of cases, all-cause death in 4%, and stroke in 1%., Conclusions: This survey, the first representative of women undergoing TAVI in Campania, appears to confirm the good safety and efficacy profile of this procedure, also in the high- and intermediate-risk settings, probably favored by a prevalent use of new-generation devices and a low rate prevalence of significant patient comorbidities.

Forty anaesthetists calculated maximum permissible doses of eight local anaesthetic formulations for simulated patients three times with three methods: an electronic calculator; nomogram; and pen and paper. Correct dose calculations with the nomogram (85/120) were more frequent than with the calculator (71/120) or pen and paper (57/120), Bayes Factor 4 and 287, p = 0.01 and p = 0.0003, respectively. The rates of calculations at least 120% the recommended dose with each method were different, Bayes Factor 7.9, p = 0.0007: 14/120 with the calculator; 5/120 with the nomogram; 13/120 with pen and paper. The median (IQR [range]) speed of calculation with pen and paper, 38.0 (25.0-56.3 [5-142]) s, was slower than with the calculator, 24.5 (17.8-37.5 [6-204]) s, p = 0.0001, or nomogram, 23.0 (18.0-29.0 [4-100]) s, p = 1 × 10 -7 . Local anaesthetic dose calculations with the nomogram were more accurate than with an electronic calculator or pen and paper and were faster than with pen and paper., (© 2017 The Association of Anaesthetists of Great Britain and Ireland.)

Background and Purpose: In Germany, all surgical and endovascular procedures on the carotid bifurcation must be documented in a statutory nationwide quality assurance database. We aimed to analyze the association between procedural and perioperative variables and in-hospital stroke or death rates after carotid endarterectomy., Methods: Between 2009 and 2014, overall 142 074 elective carotid endarterectomy procedures for asymptomatic or symptomatic carotid artery stenosis were documented in the database. The primary outcome of this secondary data analysis was in-hospital stroke or death. Major stroke or death, stroke, and death, each until discharge were secondary outcomes. Adjusted relative risks (RRs) were assessed by multivariable multilevel regression analyses., Results: The primary outcome occurred in 1.8% of patients, with a rate of 1.4% in asymptomatic and 2.5% in symptomatic patients, respectively. In the multivariable analysis, lower risks of stroke or death were independently associated with local anesthesia (versus general anesthesia: RR, 0.85; 95% confidence interval [CI], 0.75-0.95), carotid endarterectomy with patch plasty compared with primary closure (RR, 0.71; 95% CI, 0.52-0.97), intraoperative completion studies by duplex ultrasound (RR, 0.74; 95% CI, 0.63-0.88) or angiography (RR, 0.80; 95% CI, 0.71-0.90), and perioperative antiplatelet medication (RR, 0.83; 95% CI, 0.71-0.97). No shunting and a short cross-clamp time were also associated with lower risks; however, these are suspected to be confounded., Conclusions: Local anesthesia, patch plasty compared with primary closure, intraoperative completion studies by duplex ultrasound or angiography, and perioperative antiplatelet medication were independently associated with lower in-hospital stroke or death rates after carotid endarterectomy., (© 2017 American Heart Association, Inc.)

Objective: To compare clinical outcomes and complication rates in patients undergoing injection laryngoplasty performed under local versus general anaesthesia., Methods: A retrospective review was conducted of patients who underwent injection laryngoplasty performed by a single laryngologist in a tertiary Australian laryngology centre, between February 2013 and December 2014. Patient demographics, anaesthetic modality and complications were recorded. Voice Handicap Index 10 and the Grade, Breathiness, Roughness, Asthenia, Strain scale were evaluated., Results: Thirty-four laryngoplasties were performed under general anaesthesia and 41 under local anaesthesia, with mean patient ages of 59.5 and 68.8 years, respectively. Voice Handicap Index 10 scores were significantly improved post-injection (p 0.05). All aspects of the Grade, Breathiness, Roughness, Asthenia, Strain scale showed significant improvement post-injection, except asthenia. There were seven (9.3 per cent) minor complications (five in the general anaesthesia group, two in the local anaesthesia group), all managed conservatively., Conclusion: Injection laryngoplasties performed under general anaesthesia and local anaesthesia offer similar voice outcomes, with comparable complication rates. Hence, development of a management algorithm for injection laryngoplasties performed under local anaesthesia is recommended.

Objectives: To evaluate the associations between anesthesia and dementia or Alzheimer's disease (AD) risk using prospectively collected data., Design: Cohort study., Participants: Community-dwelling members of the Adult Changes in Thought cohort aged 65 and older and free of dementia at baseline (N = 3,988)., Measurements: Participants self-reported all prior surgical procedures with general or neuraxial (spinal or epidural) anesthesia at baseline and reported new procedures every 2 years. People undergoing high-risk surgery with general anesthesia, other surgery with general anesthesia, and other surgery with neuraxial anesthesia exposures were compared with those with no surgery and no anesthesia. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for dementia and AD associated with time-varying lifetime and recent (past 5 years) anesthesia exposures., Results: At baseline, 254 (6%) people reported never having anesthesia; 248 (6%) had had one or more high-risk surgeries with general anesthesia, 3,363 (84%) had had one or more other surgeries with general anesthesia, and 123 (3%) had had one or more surgeries with neuraxial anesthesia. High-risk surgery with general anesthesia was not associated with greater risk of dementia (HR = 0.86, 95% CI = 0.58-1.28) or AD (HR = 0.95, 95% CI = 0.61-1.49) than no history of anesthesia. People with any history of other surgery with general anesthesia had a lower risk of dementia (HR = 0.63, 95% CI = 0.46-0.85) and AD (HR = 0.65, 95% CI = 0.46-0.93) than people with no history of anesthesia. There was no association between recent anesthesia exposure and dementia or AD., Conclusion: Anesthesia exposure was not associated with of dementia or AD in older adults., (© 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.)

Background: The first line approach to managing healthy anxious children requiring dental extractions should include behavioural management and treatment under local anaesthetic. This can be coupled with conscious sedation., Aim: To evaluate alternative methods attempted prior to treatment under general anaesthesia (GA), to establish the incidence of repeat GA procedures., Method: Paediatric cases requiring dental extractions under GA were audited from October 2014 - December 2014 in the Oral and Maxillofacial Department, Great Western Hospital, Swindon., Results: 78 paediatric cases requiring dental extractions were carried out during the study period. 91% of referrals came from local general dental practitioners (GDPs). The indication for the GA was included in 59% of the referral letters. The number of teeth extracted per case ranged from 1 - 14. In 18% of cases treatment under local anaesthetic had been attempted previously. Conscious sedation had not been attempted in any of the cases. There were 5 cases (6.4%) of repeat general anaesthetic procedures., Conclusion: Local guidance regarding appropriate paediatric referrals should be distributed to primary care referrers. Treatment under conscious sedation should be considered for paediatric cases and an improved referral pathway to the community dental service should be developed. Preventative advice should be reinforced to the referrer and to the patient.

The National Health Service anaesthesia annual activity (2013) was recently reported by the Fifth National Audit Program of the Royal College of Anaesthetists and the Association of Anaesthetists of Great Britain and Ireland. Within a large dataset were 620 dental cases. Here, we describe this data subset. The estimated annual dental caseload was 111,600:60% were children (< 16 y), 38.5% adults (16 - 65y) and 1.5% the elderly (> 65y). Almost all were elective day procedures (97%) and ASA 1 or 2 patients (95%).The most senior anaesthetist present was a Consultant in 82% and a non-career grade doctor in 14%.Virtually all (98%) cases were conducted during GA. Propofol was used to induce anaesthesia in almost all adults compared with 60% of children. Propofol maintenance was used in 5% of both children and adults. Almost all adults received an opioid (including remifentanil) compared with only 40% of children. Thirty one per cent of children had a GA for a dental procedure without either opioid or LA supplementation. Approximately 50% of adults and 16% of children received a tracheal tube: 20% of children needed only anaesthesia by face mask. These data show that anaesthetists almost always use general anaesthesia for dental procedures and this exposes difficulties in training of anaesthetists in sedation techniques. Dentists, however, are well known to use sedation when operating alone and our report provides encouragement for a comprehensive survey of dental sedation and anaesthesia practice in both NHS and non-NHS hospitals and clinics in the UK.

Pain management is a main determinant of functional recovery after total knee arthroplasty (TKA). We performed a randomized, controlled, double blind study to evaluate additive efficacy of periarticular anesthesia in patients undergoing TKA in reducing post-operative pain, operated limb edema and improving post-operative mobility. Patients were randomly assigned to study or control group; all subjects received the same analgesic protocol; before wound closure, the study group received also a periarticular anesthesia (ropivacaine 1% 20 mL). The results show no statistical differences in any of the variable evaluated. Our data suggest that additive periarticular anesthetic protocol with ropivacaine 1% 20 mL is not superior to oral and intravenous analgesia alone in patients undergoing TKA, regarding post-operative pain control, operated limb edema reduction and post-operative mobility improvement., (Copyright © 2015 Elsevier Inc.

We hypothesised that local infiltration of anaesthesia (LIA) containing adrenaline may reduce peri-operative blood loss and transfusion requirements in primary total knee arthroplasty patients (TKA) when compared to simple patient control analgesia (PCA). In this retrospective cohort study there were 22 TKAs in the PCA group and 27 TKAs in the LIA group. There were no drains used or significant differences in demographics between groups. There was a statistically significant difference in blood loss (P = 0.003), between the LIA group (M = 942 ml, CI 829-1055), and the PCA group (M = 1314 ml, CI 1099-1527). Patients receiving PCA were 4.3 times more likely to require blood transfusion. Using the LIA technique reduces blood loss and risk of blood transfusion., (Copyright © 2015 Elsevier Inc.

The aim of this study was to assess the impact of extraction of third molars on the occurrence of temporo-mandibular disorders (TMD). A review of the literature and a case-control study have been conducted. The case-control study compares the frequency of extraction of third molars between the sample with TMD (case) and the sample without TMD (control). The proportion of patients who had undergone extractions of wisdom teeth was higher in the case group than in the control group. The difference was statistically significant when patients had undergone extraction of all four wisdom teeth or when the extraction of four wisdom teeth underwent in one sitting or under general anesthesia. The study of patients in case sample shows that all signs of TMD were more common in patients who had undergone extractions in several sessions and under local anesthesia. The temporomandibular joint sounds are significantly more frequent with local anesthesia. In the case group, 85 to 92% of patients have parafunctions and 5 to 11% have malocclusion. This demonstrates the multifactorial etiology of temporomandibular disorders., (© EDP Sciences, SFODF, 2015.)

Patients frequently experience postoperative pain after a total knee arthroplasty; such pain is always challenging to treat and may delay the patient's recovery. It is unclear whether local infiltration or a femoral nerve block offers a better analgesic effect after total knee arthroplasty.We performed a systematic review and meta-analysis of randomized controlled trials to compare local infiltration with a femoral nerve block in patients who underwent a primary unilateral total knee arthroplasty. We searched Pubmed, EMBASE, and the Cochrane Library through December 2014. Two reviewers scanned abstracts and extracted data. The data collected included numeric rating scale values for pain at rest and pain upon movement and opioid consumption in the first 24 hours. Mean differences with 95% confidence intervals were calculated for each end point. A sensitivity analysis was conducted to evaluate potential sources of heterogeneity.While the numeric rating scale values for pain upon movement (MD-0.62; 95%CI: -1.13 to -0.12; p=0.02) in the first 24 hours differed significantly between the patients who received local infiltration and those who received a femoral nerve block, there were no differences in the numeric rating scale results for pain at rest (MD-0.42; 95%CI:-1.32 to 0.47; p=0.35) or opioid consumption (MD 2.92; 95%CI:-1.32 to 7.16; p=0.18) in the first 24 hours.Local infiltration and femoral nerve block showed no significant differences in pain intensity at rest or opioid consumption after total knee arthroplasty, but the femoral nerve block was associated with reduced pain upon movement.

Context: Several studies have analyzed the long-term survival after transcatheter aortic valve implantation (TAVI). However, no previous studies have looked at survival beyond 1-year with respect to the type of anesthesia., Aims: The aim was to evaluate the mid-term survival after TAVI with respect to the type of anesthesia (general anesthesia [GA] vs. local anesthesia ± sedation [LASedation]) or the type of procedure (transfemoral [transfem] vs. transapical TAVI) performed., Settings and Design: Retrospective cohort study., Subjects and Methods: This retrospective study included TAVI's between January 2009 and June 2013. Patients were divided into three groups: transfem TAVI under GA, transfem TAVI under LASedation and transapical TAVI. A total of 176 patients were eligible. The following clinical outcomes were evaluated: (1) Mortality, (2) Major cardiovascular complications, (3) Conduction abnormalities and arrhythmias, (4) Acute kidney injury, (5) Aortic regurgitation, (6) Neurologic events, (7) Vascular complications, (8) Pulmonary complications, (9) Bleeding, (10) Infectious complications, (11) Delirium., Statistical Analysis Used: A Kruskal-Wallis test was performed to test significance between the three groups for quantitative variables. Categorical variables were compared using a Chi-square test. Survival was estimated using Kaplan-Meier method., Results: There was no statistically significant difference between the survival of both transfem TAVI's (P = 0.46). The short-term outcome of the transfem TAVI groups was better than the transapical arm, but their mid-term survival did not show any significant difference (P = 0.69 transapical vs. transfem GA; P = 0.07 transapical vs. transfem LASedation)., Conclusions: Our results demonstrate that the type of anesthesia and the access route do not influence mid-term survival after TAVI.

Background: Surgeons and anesthetists must respond to the perioperative mortality associated with general anesthesia in developing countries. The safety of performing major neonatal surgery under local anesthesia is one pragmatic response. This study describes and evaluates such practice in a tertiary pediatric surgery center in Bangladesh., Methods: Seven hundred and twenty neonates were admitted for major surgery during a 3.5-year study period. Hundred and fifty two neonates died pre-operatively, and 568 underwent major neonatal surgery. 352 (62.0%) neonates were operated under general anesthesia, while the 216 most fragile neonates (38.0%) were operated with local infiltrative anesthesia alone. Medical files were reviewed; data were collected prospectively; mortality risk factors were assessed by univariate and multivariate analysis., Results: Two hundred and sixteen procedures were performed under local anesthesia: sigmoid colostomies (37.5%), laparotomies with anastomosis (21.3%), anoplasties (18.1%), laparotomies with enterostomy (8.3%), closures of abdominal wall defects (6.9%), fixations of silastic bags (3.7%), peritoneal tube drainage (2.3%), and gastrostomies (1.9%). Median weight was 2,400 g (2,200-2,460), median gestational age was 37.0 weeks (36.0-38.0), and median age at surgery was 5.0 days (3.0-14.7). In-hospital postoperative mortality was 10.6% among those selected for local anesthesia, and 11.4% among neonates operated under general anesthesia. Low birth weight was an independent risk factor for mortality on multivariate analysis (OR 1.002 g(-1), 95% CI [1.000-1.004], p = 0.029)., Conclusions: Local anesthesia is an established option for the most fragile neonates with major surgical disease. Safe anesthesia ought to be accessible to all children of the world. The global pandemic of perioperative mortality needs to be addressed.
