Objectives Materials and Methods Results Conclusions A network meta‐analysis (NMA) was applied to compare the therapeutic effect of different acupuncture methods on temporomandibular disorder (TMD).A computer retrieval was carried out in the English databases of Cochrane, PubMed, Embase and Web of Science, as well as the Chinese databases of CNKI, Wanfang and VIP for randomized controlled trials on the effect of acupuncture on TMD, with a retrieval deadline of January 21, 2024. Data analysis was conducted using R software and Bayesian method. The pain score served as the primary outcome measure, with the mouth opening as the secondary outcome measure.Thirty‐five articles were included in the analysis, involving 1937 TMD patients. The NMA results suggested that DN‐PT had the best effect on relieving pain and improving mouth opening. (Description of all abbreviations in Supplementary Material S3).Based on the available evidence, the results of the NMA suggest that DN‐PT is most effective in relieving TMD pain and increasing mouth opening. However, due to the fact that some acupuncture therapies are only reported in a small number of research reports, this may lead to an increase in the randomness of the results and a decrease in the reliability.

The procedure with the highest rate of opioid prescription in plastic surgery is abdominoplasty. Additionally, plastic surgery patients are at a particularly elevated risk of becoming opioid-dependent. The main objective of this study was to perform a systematic review and create an algorithm for a multimodal pain regimen specific to patients undergoing abdominoplasty. A systematic search of the research literature was performed to summarize the prevailing understanding of multimodal pain control in the management of abdominoplasty. The initial search yielded 448 articles. Sixty-eight manuscripts were identified for full-text review. The effectiveness of current strategies was evaluated by way of pain scores, opioid usage, and length of stay, as well as other measures of physical function such as time to early mobilization. In 32 studies involving 2451 patients, the efficacy of different pain regimens during abdominoplasty was evaluated. Among nontraditional, opioid-sparing analgesia, efficacy of treatment interventions for improved pain and decreased opioid usage was found inall studies. Among local infusion studies, efficacy of treatment interventions for improved pain and decreased opioid usage was found in 78% of studies. Last, among regional block studies, efficacy of treatment interventions for improved pain was found in 87%, with 73% efficacy for decreased opioid usage. Multimodal pain regimens in abdominoplasty have the potential to play an important role in opioid-sparing practices in medicine by incorporating nonopioid pain adjuvants such as nonsteroidal anti-inflammatory drugs and transversus abdominis plane blocks in the preoperative, perioperative, and postoperative periods.

Introduction Mobile applications (apps) may be beneficial to promote self-management strategies to mitigate the risk of developing post-traumatic osteoarthritis in military members following a traumatic knee injury. This study investigated the efficacy of a mobile app in facilitating behavior modification to improve function and symptomology among military members. Materials and Methods This is a preliminary pre and post hoc analysis of a randomized control trial. The MARX scale, Intermittent and Constant Osteoarthritis Pain (ICOAP) questionnaire, and the Knee Injury and Osteoarthritic Outcome Score Readiness to Manage Osteoarthritis Questionnaire were completed at baseline, 6-week, 6-month, and 12-month follow-up. Participants in the treatment arm completed the System Usability Scale. Data were analyzed using descriptive statistics, the Wilcoxon sum of ranks test, the Wilcoxon signed-rank test, and Cohen's d effect size. Results A total of 28 participants were included. Between-group differences for baseline and 6-week follow-up were significantly improved in the injured knee ICOAP constant pain score for the treatment group (treatment: −4.2 ± 12, 95% CI: −11.5, 3.1; control: 5.5 ± 9.9, 95% CI: 0.9, 10.1; P  = .035, effect size = 0.905). Within-group differences for baseline and 6-week follow-up demonstrated a significant decline in the injured knee ICOAP constant pain score among the control group (signed-rank: 16.0, P  = .031, Cohen's d  = 0.339). No other significant differences were observed. A good System Usability Scale score for usability was found (76.6 ± 8.8). Conclusions These results indicate that the mobile app is easy to use and may contribute to improved constant pain symptomology for patients at risk for post-traumatic osteoarthritis.

Introduction: Pain assessment in horses presents a significant challenge due to their nonverbal nature and their tendency to conceal signs of discomfort in the presence of potential threats, including humans. Therefore, this study aimed to identify pain-associated behaviors amenable to automated AI-based detection in video recordings. Additionally, it sought to determine correlations between pain intensity and behavioral and postural parameters by analyzing factors such as time budgets, weight shifting, and unstable resting. The ultimate goal is to facilitate the development of AI-based quantitative tools for pain assessment in horses. Materials and methods: A cohort of 20 horses (mean age 15 ± 8) admitted to a university equine hospital underwent 24-h video recording. Behaviors were manually scored and retrospectively analyzed using Loopy® software. Three pain groups were established based on the Pain Score Vetmeduni Vienna: pain-free (P0), mild to moderate pain (P1), and severe pain (P2). Results: Weight shifting emerged as a reliable indicator for discriminating between painful and pain-free horses, with significant differences observed between pain groups (p < 0.001) and before and after administration of analgesia. Additionally, severely painful horses (P2 group) exhibited lower frequencies of feeding and resting standing per hour compared to pain-free horses, while displaying a higher frequency of unstable resting per hour. Discussion: The significant differences observed in these parameters between pain groups offer promising prospects for AI-based analysis and automated pain assessment in equine medicine. Further investigation is imperative to establish precise thresholds. Leveraging such technology has the potential to enable more effective pain detection and management in horses, ultimately enhancing welfare and informing clinical decision-making in equine medicine.

Background: Prior studies focus primarily on surgical outcomes of anal fistula treatment, such as healing rates, rather than patient‐reported outcomes, such as postoperative pain, which could influence surgical choice. Objective: To compare pain scores at 6 and 24 h postoperatively between laser closure and ligation of the intersphincteric tract for anal fistula. Design: Prospective, double‐blinded randomized controlled trial. Settings: A quaternary hospital in Malaysia. Patients: Patients aged 18–75 years with high transsphincteric fistulas. Intervention: Fistula laser closure versus ligation of the fistula tract (LIFT) treatment. Main Outcome Measures: Pain scores, continence, quality of life (QOL), operative time, and treatment failure were compared using chi‐square, Fisher's exact test, student t‐test, or Mann–Whitney with p < 0.05 denoting statistical significance. Results: Fifty‐six patients were recruited (laser, n = 28, LIFT, n = 28). Median pain scores for laser versus LIFT at 6 h postoperatively were 1.0 versus 2.0 (Rest, p = 0.213) and 3.0 versus 4.0 (Movement, p = 0.448), respectively. At 24 h, this reduced to 2.5 in both arms at rest (p = 0.842) but increased to 4.8 versus 3.5 on movement (p = 0.383). Median operative time for laser was significantly shorter (32.5 min) than LIFT (p < 0.001). Laser treated patients trended toward quicker return to work (10.5 vs. 14.0, p = 0.181) but treatment failure was similar (54% vs. 50%, p = 0.71). No patients developed postoperative incontinence. Mean SF‐36 scores increased from baseline (67.1 ± 17.0; 95% CI 63.6–82.4 vs. 71.3 ± 11.4; 95% CI 64.0–75.0) to 6 months postoperatively (77.7 ± 21.0; 95% CI 57.0–80.3 vs. 74.0 ± 14.3; 95% CI 67.6–81.4) regardless of the type of surgery (P > 0.05). Limitations: Patients with prior fistula surgery (approximately 20%) led to heterogeneity. The total laser energy delivered varied depending on fistula anatomy. Conclusion: Laser fistula closure is an alternative to LIFT, with similar postoperative pain and shorter operative time despite more complex fistula anatomy in the laser arm, with a greater improvement in QOL. Trial Registration: ClinicalTrials.gov: NCT06212739. [ABSTRACT FROM AUTHOR]

Background: Recurrent aphthous stomatitis (RAS) is a common chronic inflammatory oral disease that negatively impacts the quality of life. Current therapies aim to reduce pain and healing process yet challenges such as rapid loss due to salivary flushing in topical drugs and adverse effects due to prolonged use of systemic medications require further notice. Low-level laser therapy is reported with immediate pain relief and faster healing thus preserving the potential for optimal treatment modalities. This review critically analyses and summarizes the effectiveness of LLLT in reducing pain scores and healing time of RAS. Methods: A systematic search was conducted in ScienceDirect, PubMed, and Scopus using keywords of low-level laser therapy, photo-biomodulation therapy, and recurrent aphthous stomatitis. RCTs between 1967 to June 2022, presenting characteristics of the laser and reporting pain score and/or healing time of RAS after irradiation were included. Animal studies and recurrent aphthous ulcers with a history of systemic conditions were excluded. Studies were critically appraised using the RoB 2 tool. A meta-analysis was performed using inverse variance random effects. Results: Fourteen trials with a total of 664 patients were included. Reduced pain was reported in 13 studies, while shortened healing time was presented in 4. The pooling of two studies after CO2 irradiation demonstrated faster healing time compared to placebo (MD − 3.72; 95% CI − 4.18, − 3.25). Conclusion: Pain score and healing time of RAS were reduced after irradiation with LLLT. RoB resulted in "some concerns" urging well-designed RCTs with larger samples to further assess each laser application for comparison. Systematic review registration: PROSPERO CRD42022355737.

Background: Anterior knee pain is one of the most important nagging factors following ‘total knee arthroplasty’. It requires adequate redressal to avoid patient dissatisfaction, undue psychological stresses and inflated costs due to readmission and reoperation. Aims: To assess the functional outcome prospectively in total knee arthroplasty with or without patellar resurfacing. Materials and Methods: A prospective randomised study involving 25 patients undergoing bilateral total knee arthroplasty (TKA) was carried out to study the outcome after TKA with patellar resurfacing (group I) and without patellar resurfacing (group II). The onlay surgical technique was used for patellar preparation, and a cemented all-polyethylene dome-shaped patellar button with three pegs was used for implantation. The Knee Society Score (KSS), Knee Functional Score (KFS) and visual analogue score were used for clinical assessment. Results: All outcomes were assessed after 1 year of follow-up in both the groups. There was a statistically significant difference between the group I and group II knees in the mean pain score (P < 0.001), 47.8 and 41.2, respectively, in the visual analogue score (P = 0.002), 0.76 and 1.56, respectively, and the mean KSS (P < 0.001), 90.28 and 84.16, respectively. However, there was no difference in the mean pre-operative and post-operative KFS between the two groups (P = 1.000), 45.00 (standard deviation [SD] ± 12.22) and 88.72 (SD ± 10.33), respectively. There was no statistical difference in the complication rates between the two groups. Conclusions: There is a significant improvement in anterior knee pain after patella resurfacing resulting in higher patient satisfaction.

Abstract Background It was typically necessary to place a closed thoracic drainage tube for drainage following esophageal cancer surgery. Recently, the extra use of thoracic mediastinal drainage after esophageal cancer surgery had also become more common. However, it had not yet been determined whether mediastinal drains could be used alone following esophageal cancer surgery. Methods A total of 134 patients who underwent esophageal cancer surgery in our department between June 2020 and June 2023 were retrospectively analyzed. Among them, 34 patients received closed thoracic drainage (CTD), 58 patients received closed thoracic drainage combined with mediastinal drainage (CTD-MD), while 42 patients received postoperative mediastinal drainage (MD). The general condition, incidence of postoperative pulmonary complications, postoperative NRS score, and postoperative anastomotic leakage were compared. The Mann-Whitney U tests, Welch’s t tests, one-way ANOVA, chi-square tests and Fisher’s exact tests were applied. Results There was no significant difference in the incidence of postoperative hyperthermia, peak leukocytes, total drainage, hospitalization days and postoperative pulmonary complications between MD group and the other two groups. Interestingly, patients in the MD group experienced significantly lower postoperative pain compared to the other two groups. Additionally, abnormal postoperative drainage fluid could be detected early in this group. Furthermore, there was no significant change in the incidence of postoperative anastomotic leakage and the mortality rate of patients after the occurrence of anastomotic leakage in the MD group compared with the other two groups. Conclusions Using mediastinal drain alone following esophageal cancer surgery was equally safe. Furthermore, it could substantially decrease postoperative pain, potentially replacing the closed thoracic drain in clinical practice.

Low back disorder (LBD) is a major cause of disability worldwide. Inflammation results in proliferation of cytokines or consequent degradation products (collectively known as inflammatory biomarkers) that activate pain pathways which can result in non-specific LBD. This systematic review and meta-analysis aim to evaluate the relationship between inflammatory biomarkers and clinical outcomes in patients with LBD. The PRISMA guideline was followed for the systematic reivew. Three online databases were searched. Four RCTs and sixteen observational studies with 1142 LBD patients were analysed. The primary outcomes were back and leg pain scores, back-specific disability scores and expression of inflammatory biomarkers. Standardized mean difference (SMD) and their 95% confidence intervals (CI) were evaluated. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to summarize the strength of evidence. Four RCTs and sixteen observational studies were included in the analysis of 1142 patients with LBD. There was a statistically significant reduction in back pain score and IL-1 beta and increase in the expression of CTX-1 and IL-10 levels post treatment. There was a significant relationship between increase in the expression of MCP- and reduction in the expression of hsCRP with increase in back pain. Significant relationship was also observed between increase in the expression of MCP-1 and reduction in the expression of IL-6 with increase in leg pain. Increase in the expression of IL-8 and reduction in the expression of hsCRP was also associated with increased disability score. Inflammatory biomarkers play a significant role in the pathogenesis of LBD. CTX-1, IL-10 and IL-1 beta may be responsible for the decrease in back pain scores post treatment. There is a relationship between MCP-1, IL-6, IL-8 and hsCRP with clinical and functional assessments for LBD. Further studies will improve understanding of the pathogenesis of LBD and aid in targeted management strategies. [ABSTRACT FROM AUTHOR]

OBJECTIVE To compare the effectiveness of preoperative bupivacaine inferotemporal retrobulbar blocks to postoperative liposome- encapsulated bupivacaine (Nocita) line blocks for analgesia following enucleation. ANIMALS 39 client-owned dogs (40 eyes) presenting to the Ophthalmology Service for enucleation. METHODS Dogs were randomly assigned to receive either a preoperative inferotemporal retrobulbar block with 0.5% bupivacaine ora peri-incisionalline block with liposome-encapsulated bupivacaine (Nocita) at closure. Patients underwent unilateral enucleation and were hospitalized for 24 hours after surgery. Pain scores were performed by a masked observer with the Glasgow Composite Measure Pain Scale and the University of Wisconsin Ocular Pain Scale at 0.25, 0.5,1,2,4,6,8, and 24 hours following surgery. Intraoperative use of blood pressure and anesthetic support mediations as well as need for rescue pain control were recorded and compared between groups. RESULTS There was no significant difference in rescue rates between treatment groups. When comparing the use of medical intraoperative heart rate, blood pressure, or anesthetic plane support, there were no significant differences in use between groups. CLINICAL RELEVANCE Use of preoperative bupivacaine retrobulbar blocks and postoperative Nocita line blocks were equally effective at postoperative pain control with similarly low complication rates.

This report describes the combined use of the ultrasound‐guided subcostal and lateral transversus abdominis blocks as part of the multimodal analgesia in a 3‐month‐old calf, presented for omphalitis surgical repair. It was premedicated with xylazine, anaesthesia was induced with ketamine and maintained by isoflurane in oxygen. The block was performed with lidocaine 2%, and flunixin meglumine was administered pre‐ and postoperatively. Postoperative pain was scored, and rescue analgesia was not required intra‐ and postoperatively. Pain assessment and multimodal analgesia are crucial in food‐producing animals. Employing bilateral ultrasound‐guided lateral and subcostal transversus abdominis plane block can prove advantageous as part of the multimodal analgesia protocol for calves undergoing umbilical surgeries. Furthermore, it is essential to delv into the discussion of lidocaine's toxic dosage when applied in locoregional techniques. [ABSTRACT FROM AUTHOR]

Simple Summary: Local anaesthetic nerve blocks can be used to provide pain relief during and after surgery. While specific local anaesthetic techniques are commonplace in humans and some species, it is a relatively new field of research in rabbits. Rabbits are prey species that hide pain well but may express changes in behaviour, food intake, and production of faeces as a result of pain, making them challenging to study. This study aimed to investigate a specific local anaesthetic technique in rabbits undergoing orthopaedic surgery on a front leg. Its effectiveness was investigated by comparing the requirement for extra pain relief during and after surgery and comparing changes in food intake, faeces production, and behaviour after surgery. Both remote filming and direct observation were used. The rabbits who received the block required no additional pain relief during surgery, whereas every rabbit who received intravenous pain relief did require additional pain relief. However, after surgery, the severity of pain and the requirement for extra pain relief were the same, and there was no difference in behaviour between the groups. In conclusion, this local anaesthetic nerve block was easy to administer and provided effective pain relief during surgery, reducing the need for additional drug therapy. Locoregional anaesthetic techniques are invaluable for providing multimodal analgesia for painful surgical procedures. This prospective, randomised study describes a nerve stimulator-guided brachial plexus blockade (BPB) in rabbits undergoing orthopaedic surgery in comparison to systemic lidocaine. Premedication was provided with intramuscular (IM) medetomidine, fentanyl, and midazolam. Anaesthesia was induced (propofol IV) and maintained with isoflurane. Nine rabbits received a lidocaine BPB (2%; 0.3 mL kg−1), and eight received a lidocaine constant rate infusion (CRI) (2 mg kg−1 IV, followed by 100 µg kg−1 min−1). Rescue analgesia was provided with fentanyl IV. Carprofen was administered at the end of the surgery. Postoperative pain was determined using the Rabbit Grimace Scale (RGS) and a composite pain scale. Buprenorphine was administered according to the pain score for two hours after extubation. Rabbits were filmed during the first two hours to measure distance travelled and behaviours. Food intake and faeces output were compared. Every rabbit in CRI required intraoperative rescue analgesia compared to none in BPB. However, rabbits in both groups had similar pain scores, and there was no difference in the administration of postoperative analgesia. There were no significant differences in food intake or faeces production over 18 h, and no significant differences in distance travelled or behaviours examined during the first two hours. BPB seems superior for intraoperative analgesia. Postoperatively, both groups were comparable. [ABSTRACT FROM AUTHOR]

Establishing objective criteria to assess endometriosis symptoms is crucial in defining therapeutic strategies. The visual analogue scale (VAS) is the most used system to enhance the accuracy and reduce the subjectivity of pain assessment, and symptoms of endometriosis are considered severe when the VAS score is ≥ 7 cm. Pain symptoms can significantly impact patients' quality of life, resulting in psychological and social distress. The aim of this study is to evaluate whether a VAS cut-off point of 7 cm for each pain symptom correlates with a diminished quality of life in women with endometriosis. This retrospective study included 1129 patients who underwent surgical treatment for endometriosis. Dysmenorrhea, acyclic pelvic pain, deep dyspareunia, dyschezia, and dysuria were assessed using a 0–10 cm VAS. The Short Form-36 (SF-36) questionnaire was employed to evaluate the quality of life 6 months prior to surgery. Dysmenorrhea was the most prevalent symptom reported in 93.6% of cases, with a mean VAS of 7.6 cm. The quality of life reported was reduced in most patients, with domain scores ranging from 49.4 to 80.1. The mean SF-36 scores in all domains were significantly lower in patients with severe pain (VAS score ≥ 7 cm) compared to those with mild to moderate pain (VAS < 7 cm). This trend was observed across all evaluated pain symptoms. Our research demonstrates that the prevalent VAS cut-off point for establishing severe pain symptoms in endometriosis (VAS ≥ 7 cm) accurately represents the negative impact of the disease on women's quality of life, as assessed via the SF-36 questionnaire.

BackgroundAcute pancreatitis is an inflammatory disease that can lead to persistent organ failure (POF), which is associated with increased morbidity and mortality. Early prediction of POF in AP can significantly improve patient outcomes.ObjectiveTo develop and validate a nomogram that combines pain score with laboratory indicators for predicting POF in patients with AP.MethodsA retrospective cohort study was conducted, including patients diagnosed with AP. Pain score and laboratory indicators were collected within the first 24 h of admission. A nomogram was developed using logistic regression models and validated in a separate cohort.ResultsThere were 807 patients in the training cohort and 375 patients in the internal validation cohort.Multivariate logistic regression demonstrated that pain score, serum creatinine, hematocrit, serum calcium, and serum albumin were independent risk factors for the incidence of POF in patients with AP. The area under the curve of the nomogram constructed from the above factors were 0.924, respectively. The model demonstrated good calibration and discrimination in both the development and validation cohorts.ConclusionThe nomogram had a good performance in predicting POF in patients with AP and can be used to guide clinical decision-making.

Abstract Background Rabbits are popular family pets. They are prey species and so have evolved to hide signs of illness and pain. Recent research has developed robust pain scales for use in a clinical setting, but to date none has examined rabbit owners’ ability to recognise pain in their animals. This study investigated how owners identify pain in their pet rabbits and their ability to correctly identify different levels of pain, in order to determine any need for owner education in this area. Methods Owners were recruited via Facebook and a two-part online survey was distributed. Part one collected data on demographics, owners’ knowledge of pain signs and beliefs about pain in rabbits. Part two asked respondents to pain score eight videos of rabbits in different levels of pain for comparison to pain scores made by three experts. We used a simplified version of the Bristol Rabbit Pain Score (BRPS) which involved a single 0 to 3 scale. We explored the number of pain signs each respondent could list, the total score given to the videos, and their deviation from the experts’ scores. Results A total of 500 respondents completed part one of the survey and 345 additionally completed Part two. Respondents were on average able to state five signs of pain (range 0–12), but females stated significantly more (p = 0.018), as did those who worked with rabbits (p = 0.004) and those with experience of their rabbit having an operation (p = 0.01). Overall, 98.6% of respondents thought rabbits felt pain as much or more that dogs and cats. In Part two, respondents more frequently agreed with the experts when identifying rabbits in no pain (88.8%) and severe pain (65.2%), but there was lower agreement when identifying mild (28.4%) and moderate pain (43.2%). Respondents overall rated pain lower than experts with an average total pain score of 11.9 compared to 18 given by the experts. Conclusions Most rabbit owners are able to list numerous pain signs and are generally able to identify pain-free rabbits and those in severe pain. Owners’ ability to differentiate between mild and moderate pain is more limited and could benefit from training in the subtler signs of pain. Veterinary professionals are well placed to educate owners about signs of pain in rabbits and should be aware of areas where owners’ knowledge can be improved.

Background: Ultrasound therapy is one of the preferred conservative treatments for patients with plantar fasciitis. This study aims to evaluate the effectiveness of therapeutic ultrasound in decreasing pain intensity and improving functional disability in patients with plantar fasciitis. Methods: Five randomised control trials (RCT) were selected based on an electronic search in PubMed, Trip Database and PEDro. To be included in the systematic review, the study should be an RCT which investigated the effectiveness of therapeutic ultrasound conducted in patients with plantar fasciitis with pain intensity and functional disability as outcome measures. Only studies published in peerreviewed journals written in the English language were included. The quality of the selected studies was measured by the PEDro scale. Results: All the included studies showed that ultrasound therapy is beneficial in reducing pain score and improving functional disability, except one study did not recommend using ultrasound therapy for plantar fasciitis. Moreover, regarding another outcome measure, two studies found that ultrasound therapy reduces thickness and tenderness in plantar fasciitis and improves static and dynamic balance. Conclusion: After reviewing the five studies, this systematic review support using ultrasound therapy to decrease pain and improve functional disability in patients with plantar fasciitis.

The results showed that different internal thoracic artery (ITA) was associated with the rate of postoperative wound infection and the severity of pain following coronary artery bypass grafting (CABG). In order to ascertain if there was any genuine difference in the rate of postoperative infection and severity of the pain, we conducted a meta‐analysis to evaluate if there was any actual difference in the wound complication that had been identified with the ITA method. Through EMBASE, Cochrane Library and Pubmed, and so forth, we systematically reviewed the results by August 2023, which compared the impact of skeletonised versus pedicled internal mammary artery (IMA) on wound complications following CABG. The trial data have been pooled and analysed in order to determine if a randomisation or fixed‐effect model should be applied. The meta‐analysis of data was performed with Revman 5.3 software. The results of this meta‐study included 252 related articles from four main databases, and nine articles were chosen to be extracted and analysed. A total of 3320 patients were treated with coronary artery transplantation. Based on current data analysis, we have shown that the rate of postoperative wound infections is reduced by the use of the skeletonised internal mammary artery (SIMA) (OR, 1.84; 95% CI, 1.13, 3.01; p = 0.01). But the results showed that there were no statistically significant differences in the post‐operation pain score of the patients (MD, 0.09; 95% CI, −0.58, 0.76; p = 0.79). Furthermore, the duration of the operation was not significantly different between the SIMA and pedicled internal mammary artery (PIMA) (MD, 3.30; 95% CI, −3.13, 9.73; p = 0.31). Overall, the SIMA decreased the rate of postoperative wound infection in CABG patients than the PIMA. [ABSTRACT FROM AUTHOR]

Background Epidural analgesia (EDA) is a main modality for postoperative pain relief in major open abdominal surgery within the Enhanced Recovery After Surgery protocol. However, it remains unclear whether EDA is an imperative modality in laparoscopic gastrectomy (LG). This study examined non-inferiority of patient-controlled intravenous analgesia (PCIA) to EDA in terms of postoperative pain and recovery in patients who underwent LG. Methods In this open-label, non-inferiority, parallel, individually randomized clinical trial, patients who underwent elective LG for gastric cancer were randomized 1:1 to receive either EDA or PCIA after surgery. The primary endpoint was pain score using the Numerical Rating Scale at rest 24 h after surgery, analysed both according to the intention-to-treat (ITT) principle and per protocol. The non-inferiority margin for pain score was set at 1. Secondary outcomes were postoperative parameters related to recovery and adverse events related to analgesia. Results Between 3 July 2017 and 29 September 2020, 132 patients were randomized to receive either EDA (n = 66) or PCIA (n = 66). After exclusions, 64 patients were included in the EDA group and 65 patients in the PCIA group for the ITT analysis. Pain score at rest 24 h after surgery was 1.94 (s.d. 2.07) in the EDA group and 2.63 (s.d. 1.76) in the PCIA group (P = 0.043). PCIA was not non-inferior to EDA for the primary endpoint (difference 0.69, one side 95% c.i. 1.25, P = 0.184) in ITT analysis. Postoperative parameters related to recovery were similar between groups. More EDA patients (21 (32.8%) versus 1 (1.5%), P < 0.001) developed postoperative hypotension as an adverse event. Conclusions PCIA was not non-inferior to EDA in terms of early-phase pain relief after LG. Registration number: UMIN000027643 (https://www.umin.ac.jp/ctr/index-j.htm). [ABSTRACT FROM AUTHOR]

Objective Our study aimed to investigate the analgesic efficacy of nebulized ketamine in managing acute moderate-to-severe musculoskeletal pain in older emergency department (ED) patients compared with intravenous (IV) morphine. Methods This was a non-inferiority, double-blind, randomized controlled trial conducted at a single medical centre. The patients aged 65 and older, who presented at the ED musculoskeletal pain within 7 days and had a pain score of 5 or more on an 11-point numeric rating scale (NRS), were included in the study. The outcomes were a comparison of the NRS reduction between nebulized ketamine and IV morphine 30 minutes after treatment, incidence of adverse events and rate of rescue therapy. Results The final study included 92 individuals, divided equally into two groups. At 30 minutes, the difference in mean NRS between the nebulized ketamine and IV morphine groups was insignificant (5.2 versus 5.7). The comparative mean difference in the NRS change from baseline between nebulized ketamine and IV morphine [−1.96 (95% confidence interval—CI: −2.45 to −1.46) and −2.15 (95% CI: −2.64 to −1.66) = 0.2 (95% CI: −0.49 to 0.89)] did not exceed the non-inferiority margin of 1.3. The rate of rescue therapy did not differ between the groups. The morphine group had considerably higher incidence of nausea than the control group (zero patients in the ketamine group versus eight patients (17.4%) in the morphine group; P  = 0.006). Conclusions Nebulized ketamine has non-inferior analgesic efficacy compared with IV morphine for acute musculoskeletal pain in older persons, with fewer adverse effects. [ABSTRACT FROM AUTHOR]

Current research has demonstrated that nonopioid multimodal analgesia decreases perioperative opioid consumption, postoperative nausea and vomiting (PONV), and pain scores. However, no research has been conducted to examine the patient outcomes of Merit-based Incentive Payment System (MIPS) 477. This study evaluates those outcomes following implementation of MIPS 477. The medical records of 400 adult patients who underwent elective and urgent laparoscopic gynecological procedures at a facility in the Mid- Atlantic region were reviewed. Data collection included patient characteristics, analgesics administered, pain scores at postanesthesia care unit (PACU) arrival and discharge, and antiemetic administration in PACU. This study's primary outcomes were postoperative pain scores, total intraoperative and postoperative opioid consumption, and PONV. Twenty-nine patients (7.8%) met the criteria as a control group, and 341 patients (92.2%) met the criteria as a treatment group. Pain scores were higher upon PACU arrival among the control group (P = .001). The total intraoperative morphine milligram equivalents (MMEs) administered was less among the treatment group (P = .04). The treatment group had reduced total intraoperative MMEs and pain scores at PACU arrival. However, there was no statistical significance in PACU discharge pain score, total PACU MMEs, and PONV in both groups. [ABSTRACT FROM AUTHOR]

Purpose: The relationship between sensitization and postoperative function in patients undergoing arthroscopic rotator cuff repair (ARCR). The purpose of this study was to evaluate the effect of pre-and postoperative reductions in the pressure pain threshold (PPT) on postoperative clinical outcomes in patients with ARCR and investigate changes in PPT and clinical outcomes resulting from postoperative administration of weak opioids activating the central inhibitory system. Methods: This retrospective study included patients who underwent primary ARCR, categorized into Group A (excellent/good Constant scores) and B (fair/poor Constant scores). In a complementary study, patients were randomized to the Control or Tramadol groups. Both studies evaluated the PPT, visual analog scale, active range of motion (ROM), Constant score, and retear rates pre-and postoperatively. Results: In the primary study with 158 patients, those with poor clinical outcomes exhibited significantly lower PPT at the affected shoulder preoperatively at 3 months postoperatively compared to those with good outcomes. The PPT of the affected side was lower than that of the uninvolved side not only at 1 and 3 months but also preoperatively and at 6 months in the poor outcome group. In the secondary study involving 96 patients, weak opioid administration was associated with increased PPT for 3 months, improved ROM at 3 months postoperatively, and reduced postoperative pain 1 year postoperatively. Conclusion: Patients experiencing poor postoperative clinical outcomes exhibited prolonged lowered PPT. Lowered PPT due to sensitization may adversely affect functional recovery and pain perception. Elevating PPT using weak opioids improved clinical outcomes during the acute perioperative period after ARCR. Level of evidence: III. [ABSTRACT FROM AUTHOR]

This study interviewed adult patients presenting to the emergency department (ED) for various pain conditions enquiring about their preferred tool for reporting pain severity and preferred time interval between initial assessment and subsequent pain reassessments. A prospective observational (cross-sectional) study was conducted in adult patients with acute pain in a tertiary care hospital ED setting. Patients' initial pain score was recorded using NRS (numerical rating scale) pain scale, and appropriate analgesia offered. Once the patient had been evaluated by an attending physician, a research team member interviewed the patient regarding the pain reassessment time and preferred pain assessment tool. The pain assessment tools evaluated in this study were NRS, PS (picture scale or face pain scale), VRS (verbal rating scale), and VAS (visual analogue scale). The patients were presented with the four pain assessment tools (in their primary language) through an audio-visual on an electronic tablet display. 200 (138 male, mean age 36.5 ± 11.17) patients participated in the study. With increasing age, pain reassessment interval increased by 0.19 min (95% CI 0.03–0.36 min). Males requested pain reassessment 6.7 min (95% CI 2.2–10.8) faster than females. In this study, the preferred interval for pain reassessment was reported as a mean of 22.8 (SD + −13.6) minutes. There was no relationship reported between time reassessment and pain severity (P = 0.22). Out of 200 subjects, irrespective of the initial pain scores, 100 preferred NRS. NRS was preferred by patients with mild to moderated pain due to the perception of being faster. However, patients with severe pain choose a non-NRS scale to prioritize accuracy. There was no influence found between the initial pain severity scores and the desired frequency of pain reassessment. However, associations were identified between the time for pain reassessment interval and age, sex, and geographical region. Patients with severe pain preferred PS or VRS while patients with mild/moderate pain preferred the NRS. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Patients undergoing spinal fusion surgery suffer from severe postoperative pain. The study aims to investigate the effectiveness of ultrasound-guided erector spinae plane block in alleviating pain following multilevel spinal fusion with instrumentation. PATIENTS AND METHODS: Forty-two patients, who were in classes I-II-III according to the American Society of Anesthesiologists (ASA) classification and were scheduled for lumbar spinal fusion surgery, were randomly divided at a ratio of 1:1 into the erector spinae plane block (ESPB) group and the control group. While an erector spinae plane block was applied before surgery in the ESPB group, no block was involved in the control group. A patient-controlled analgesia pump containing morphine was attached to each patient after surgery. The primary outcome was the amount of morphine used in 24 hours. The secondary outcomes included pain scores and rescue analgesia requirements at different time points. RESULTS: The 24-hour morphine consumption level of the ESPB group was significantly lower than that of the control group (p=0.005). Pain intensity, which was assessed using The Numerical Rating Scale (NRS), was found to be significantly lower in the ESPB group (p<0.05). NRS scores of the two groups were similar at the 12th and 24th hours (respectively, p=0.097 and p=0.157). While rescue analgesia was administered to 71.4% of the patients in the control group, it was administered to 28.6% of those in the ESPB group. The difference between the groups was significant (p=0.005). CONCLUSIONS: Ultrasound-guided bilateral erector spinae plane block in multilevel spinal fusion surgery with instrumentation alleviates severe postoperative pain and reduces opioid consumption.

The purpose of this study was to examine the efficacy of remifentanil on external cephalic version (ECV) in breech presentation. An extensive search was conducted using PubMed, Cochrane Library, and other grey literature. Only randomized controlled trials using remifentanil for ECV were included. Risk ratio (RR) and mean difference (MD) were used to estimate outcomes and quality of evidence was assessed using the Risk of Bias and GRADE system. Five studies consisting of 602 patients were analyzed. Remifentanil resulted in a moderate increase in ECV success rate (RR, 1.19; 95% CI, 1.00 to 1.43; P = .05), a large reduction of pain score (MD, -2.02; 95% CI, -2.32 to -1.72; P < .00001) with fewer transient fetal bradycardia (RR, 0.40; 95% CI, 0.19 to 0.85; P = .02). However, remifentanil did not affect cesarean section rates, (RR, 0.97; 95% CI, 0.49 to 1.93; P = .93) instrumental delivery (RR, 0.94; 95% CI, 0.41 to 2.15; P = 0.89), and spontaneous delivery rate (RR, 1.02; 95% CI, 0.78 to 1.35; P = 0.87). Mothers treated with remifentanil have a higher patient satisfaction score. The use of remifentanil may be a good strategy for ECV. However, extrapolation of this finding to clinical settings must consider the study limitations. [ABSTRACT FROM AUTHOR]

Background Ultrasound therapy is one of the preferred conservative treatments for patients with plantar fasciitis. This study aims to evaluate the effectiveness of therapeutic ultrasound in decreasing pain intensity and improving functional disability in patients with plantar fasciitis. Methods Five randomised control trials (RCT) were selected based on an electronic search in PubMed, Trip Database and PEDro. To be included in the systematic review, the study should be an RCT which investigated the effectiveness of therapeutic ultrasound conducted in patients with plantar fasciitis with pain intensity and functional disability as outcome measures. Only studies published in peer-reviewed journals written in the English language were included. The quality of the selected studies was measured by the PEDro scale. Results All the included studies showed that ultrasound therapy is beneficial in reducing pain score and improving functional disability, except one study did not recommend using ultrasound therapy for plantar fasciitis. Moreover, regarding another outcome measure, two studies found that ultrasound therapy reduces thickness and tenderness in plantar fasciitis and improves static and dynamic balance. Conclusion After reviewing the five studies, this systematic review support using ultrasound therapy to decrease pain and improve functional disability in patients with plantar fasciitis.

IntroductionPostoperative pain and complications pose significant challenges following a hemorrhoidectomy. Attaining effective anesthesia with minimal complications is crucial. The ideal anesthesia method for ambulatory hemorrhoidectomy remains uncertain. This study aimed to investigate whether the combination of general anesthesia plus local infiltration (GAL) is associated with lower complications and reduced pain compared to spinal anesthesia (SA) in the context of hemorrhoidectomy.MethodsThis retrospective single-center cohort study, conducted in a tertiary medical center in East Asia, evaluated excisional hemorrhoidectomies performed between January 1, 2017, and March 31, 2023, utilizing GAL or SA. Data on the six most common complications-pain, constipation, acute urine retention (AUR), bleeding, nausea, and headache-were extracted from medical records. A total of 550 hemorrhoidectomies were included: 220 in the GAL group and 330 in the SA group. Patient characteristics were comparable between the two groups.ResultsThe AUR rate was significantly lower in the GAL group compared to the SA group (15.5% vs. 32.1%, P < 0.001). Although the proportion of pain scores ≥4 did not differ significantly between the GAL and SA groups (36.2% vs. 39.8%, P = 0.429), the pain score curve indicated a stable trend. Overall, the GAL group exhibited a lower rate of adverse effects (56.9% vs. 67.4%, P = 0.023). There were no significant differences in the rates of other complications and emergency department readmission between the GAL and SA groups.DiscussionGAL emerges as a favorable choice for anesthesia in hemorrhoidectomy, demonstrating a lower incidence of urine retention and a prolonged analgesic effect in multiple hemorrhoidectomies. These findings support the conclusion that GAL represents an optimal anesthetic method for enhancing the postoperative experience in patients undergoing hemorrhoidectomy.

To further explore the pathogenic mechanism of lumbar disc herniation (LDH) pain, this study screens important imaging features that are significantly correlated with the pain score of LDH. The features with significant correlation imaging were included into a back propagation (BP) neural network model for training, including Pfirrmann classification, Michigan State University (MSU) regional localization (MSU protrusion size classification and MSU protrusion location classification), sagittal diameter index, sagittal diameter/transverse diameter index, transverse diameter index, and AN angle (angle between nerve root and protrusion). The BP neural network training model results showed that the specificity was 95 ± 2%, sensitivity was 91 ± 2%, and accuracy was 91 ± 2% of the model. The results show that the degree of intraspinal occupation of the intervertebral disc herniation and the degree of intervertebral disc degeneration are related to LDH pain. The innovation of this study is that the BP neural network model constructed in this study shows good performance in the accuracy experiment and receiver operating characteristic experiment, which completes the prediction task of lumbar Magnetic Resonance Imaging features for the pain degree of LDH for the first time, and provides a basis for subsequent clinical diagnosis.

Abstract Background The use of single-incision plus one-port laparoscopic pancreaticoduodenectomy (SILPD + 1) has been never reported, and its safety and efficacy remain unknown. This study aimed to evaluate the short-term outcomes of SILPD + 1 compared with those of conventional laparoscopic pancreaticoduodenectomy (CLPD). Method Fifty-seven cases of laparoscopic pancreaticoduodenectomy (LPD) were performed between November 2021, and March 2022. Among them, 10 cases of LPD were performed using a single-incision plus one-port device. Based on the same inclusion and exclusion criteria, 47 cases of LPD performed using traditional 5-trocar were included as a control group. The patient’s demographic characteristics, intraoperative, and postoperative variables were prospectively collected and retrospectively analyzed. Results Three men and seven women were included in the SILPD + 1 group. All baseline parameters of both groups were comparable, except for age. Patients were younger in the SILPD + 1 group (47.2 ± 18.3 years vs. 60.6 ± 11.7 years, P = 0.05) than that in the CLPD group. Compared with the CLPD group, median operation time (222.5 (208.8–245.0) vs. 305.0 (256.0–37.0) min, P

Locoregional anaesthetic techniques are invaluable for providing multimodal analgesia for painful surgical procedures. This prospective, randomised study describes a nerve stimulator-guided brachial plexus blockade (BPB) in rabbits undergoing orthopaedic surgery in comparison to systemic lidocaine. Premedication was provided with intramuscular (IM) medetomidine, fentanyl, and midazolam. Anaesthesia was induced (propofol IV) and maintained with isoflurane. Nine rabbits received a lidocaine BPB (2%; 0.3 mL kg−1), and eight received a lidocaine constant rate infusion (CRI) (2 mg kg−1 IV, followed by 100 µg kg−1 min−1). Rescue analgesia was provided with fentanyl IV. Carprofen was administered at the end of the surgery. Postoperative pain was determined using the Rabbit Grimace Scale (RGS) and a composite pain scale. Buprenorphine was administered according to the pain score for two hours after extubation. Rabbits were filmed during the first two hours to measure distance travelled and behaviours. Food intake and faeces output were compared. Every rabbit in CRI required intraoperative rescue analgesia compared to none in BPB. However, rabbits in both groups had similar pain scores, and there was no difference in the administration of postoperative analgesia. There were no significant differences in food intake or faeces production over 18 h, and no significant differences in distance travelled or behaviours examined during the first two hours. BPB seems superior for intraoperative analgesia. Postoperatively, both groups were comparable.

Background: The use of single-incision plus one-port laparoscopic pancreaticoduodenectomy (SILPD + 1) has been never reported, and its safety and efficacy remain unknown. This study aimed to evaluate the short-term outcomes of SILPD + 1 compared with those of conventional laparoscopic pancreaticoduodenectomy (CLPD). Method: Fifty-seven cases of laparoscopic pancreaticoduodenectomy (LPD) were performed between November 2021, and March 2022. Among them, 10 cases of LPD were performed using a single-incision plus one-port device. Based on the same inclusion and exclusion criteria, 47 cases of LPD performed using traditional 5-trocar were included as a control group. The patient's demographic characteristics, intraoperative, and postoperative variables were prospectively collected and retrospectively analyzed. Results: Three men and seven women were included in the SILPD + 1 group. All baseline parameters of both groups were comparable, except for age. Patients were younger in the SILPD + 1 group (47.2 ± 18.3 years vs. 60.6 ± 11.7 years, P = 0.05) than that in the CLPD group. Compared with the CLPD group, median operation time (222.5 (208.8–245.0) vs. 305.0 (256.0–37.0) min, P < 0.001) was shorter, median postoperative VAS scores on days 1–3 were lower, and median cosmetic score (21.0 (19.0–23.5) vs. 17.0 (16.0–20.0), P = 0.026) was higher one month after the surgery in the SILPD + 1 group. The estimated blood loss, conversion rate, blood-transfusion rate, exhaust time, time of drainage tube removal, postoperative hospital stays, and perioperative complications were comparable between the two groups. Conclusion: In a high-volume LPD center, SILPD + 1 is safe and feasible for well-selected patients without increasing the operation time and complications. It even has the advantages of reduced postoperative pain and improved cosmetic results. [ABSTRACT FROM AUTHOR]

Objective: To compare the efficacy of Nalbuphine alone versus Nalbuphine with Ketorolac for the management of pain in for open cholecystectomy under general anaesthesia. Study Design: Comparative prospective study. Place and Duration of Study: Anaesthesia department of CMH, Okara Cantt Pakistan, June 2019- March 2020. Methodology: Patients were divided into two Groups by the lottery method, Group-A, Nalbuphine (.12milligram/kilogram) and Group-B (Nalbuphine .06millig/kilogram+ Ketorolac 15milligram).They were all given standard anesthetic drugs and analgesics in above mentioned dose at the start of surgery. Patients were assessed regarding postoperative pain intensity using the Numerical Pain Rating Scale at 5minute, 30 minutes and 1 hour after shifting to recovery. Rescue analgesia for moderate to severe pain at 30 minutes was documented. Nausea, vomiting and sedation were also noted in both groups. Results: Sedation in Group A was 8(10.7%) as compared in Group-B 4(5.3%).The frequency of nausea and vomiting in Group A and Group-B was 6(8.0%), 4(5.3%), and 5(6.7%), 2(2.7%) respectively. Rescue analgesia being lower in Group-A compared to Group-B which was statistically significant, for moderate to severe pain at 30 minutes after shifting. Group-A 10(13.3%) of cases while Group-B 55(73.3%) of cases producing p-value 0.001.A statistically significant difference regarding pain score between both groups, p-value <0.001. Conclusion: Intravenous Nalbuphine (0.12 mg/kg) was more effective in reducing pain intensity and postoperative analgesic requirements after surgery as compared to Nalbuphine (.6mg/kg)+ Ketorolac (15mg) in combination.

Background Severe zoster-associated pain limits patient's daily activity and may significantly lower the patient's quality of life. Ultrasound-guided erector spinae plane (ESP) blocks are used for a wide variety of indications in the management of acute, chronic, and postoperative pain. Aim: Our aim was to evaluate the efficacy of ultrasound-guided erector spinae plane blocks and Para vertebral for the management of post herpetic neuralgia. Methods: This study was carried out on 40 patients between 18 and 60 years old suffering from acute thoracic HZ. Patients were randomly classified into two groups: one group 1 received ESPB, using 0.2% ropivacaine (20 ml volume) and Patients who received a Para vertebral nerve block constituted Group II. All patients received standard medical care. The pain score, the consumption of pregabalin and analgesics, the incidence of complications, and the patient's satisfaction were measured and recorded. Results: Numerical rating scale (NRS) showed insignificant differences at baseline. NRS for pain at 1, 3, 4, 12, and 24 weeks was significantly reduced in group ESB compared to group II. Doses of pregabalin and acetaminophen were comparable at 1 week among the studied groups. Doses of pregabalin and acetaminophen at 3, 4, 12, and 24 weeks were significantly lesser in group ESB compared to group II. After 3 months, the incidence of persistent herpetic pain was not significantly different between the study groups. After 6 months, the incidence of persistent herpetic pain was statistically significantly lower in groups ESB than in group II (P = 0.036 and 0.016, respectively) without significant difference between group I and group II. Conclusion: Ultrasound-guided erector spinae plane (ESP) block in conjunction with medical treatment can be beneficial in decreasing pain intensity in patients with acute pain due to herpes zoster more rapidly than conventional medical treatment. It leads to a significant decrease in pain score and analgesic requirements. [ABSTRACT FROM AUTHOR]

Pain monitoring is crucial to provide proper healthcare for patients during general anesthesia (GA). In this study, photoplethysmographic waveform amplitude (PPGA), heartbeat interval (HBI), and surgical pleth index (SPI) are utilized for predicting pain scores during GA based on expert medical doctors' assessments (EMDAs). Time series features are fed into different long short-term memory (LSTM) models, with different hyperparameters. The models' performance is evaluated using mean absolute error (MAE), standard deviation (SD), and correlation (Corr). Three different models are used, the first model resulted in 6.9271 ± 1.913, 9.4635 ± 2.456, and 0.5955 0.069 for an overall MAE, SD, and Corr, respectively. The second model resulted in 3.418 ± 0.715, 3.847 ± 0.557, and 0.634 ± 0.068 for an overall MAE, SD, and Corr, respectively. In contrast, the third model resulted in 3.4009 ± 0.648, 3.909 ± 0.548, and 0.6197 ± 0.0625 for an overall MAE, SD, and Corr, respectively. The second model is selected as the best model based on its performance and applied 5-fold cross-validation for verification. Statistical results are quite similar: 4.722 ± 0.742, 3.922 ± 0.672, and 0.597 ± 0.053 for MAE, SD, and Corr, respectively. In conclusion, the SPI effectively predicted pain score based on EMDA, not only on good evaluation performance, but the trend of EMDA is replicated, which can be interpreted as a relation between SPI and EMDA; however, further improvements on data consistency are also needed to validate the results and obtain better performance. Furthermore, the usage of further signal features could be considered along with SPI. [ABSTRACT FROM AUTHOR]

Optimization of perioperative analgesia has important implications for patient satisfaction and short-term outcomes. This study's purpose is to assess if preoperative gabapentin or intraoperative ketorolac influences postoperative pain or time to discharge following hip arthroscopy. In total, 409 patients who underwent hip arthroscopic femoroplasty and/or acetabuloplasty with a single surgeon for femoroacetabular impingement were retrospectively reviewed (September 2017 to February 2021). The effect of preoperative gabapentin or intraoperative ketorolac on postoperative visual analog scale (VAS) pain scores, perioperative opioids in morphine milligram equivalents (MMEs), time in post-anesthesia care unit (PACU), second-stage recovery and time to discharge was assessed using unadjusted and adjusted t -tests, and generalized linear models controlling for operative time, traction time, preoperative MME, intraoperative MME and postoperative MME were compared between the groups of gabapentin to no gabapentin and ketorolac to no ketorolac. There was no difference in first PACU VAS pain score, final PACU VAS score, VAS pain score prior to discharge, average VAS pain score or pain level on follow-up call in the unadjusted or adjusted analysis for the preoperative gabapentin or intraoperative ketorolac groups. Females had higher first PACU VAS pain score (6.05 versus 5.15 P  = 0.0026), final PACU VAS pain score (4.43 versus 3.90, P  = 0.0045), final VAS pain score prior to discharge (3.87 versus 3.03, P  < 0.001) and average postoperative pain score (4.60 versus 4.03, P  < 0.001), but no difference in VAS pain score on follow-up call following surgery. Gabapentin or ketorolac was not associated with decreased VAS pain scores or time to discharge after hip arthroscopy. [ABSTRACT FROM AUTHOR]

ObjectivesTo evaluate a modified ovariohysterectomy (OHE) technique performed by a single person and compare it with the conventional method based on time efficiency, trauma, and postoperative pain.MethodsIn a prospective, randomized, experimental study, 18 healthy, large, deep-chested, mixed-breed intact female dogs were randomly allocated to conventional (n = 9) and instrument shank-assisted (n = 9) groups. On the basis of video recordings, the various surgical step durations were analyzed: total surgery time (TST), pedicle intervention time (PIT), suspensory release time (SRT), shanking time (ShT), clamping time (ClpT), ligating time (LigT), and closure time (CT). The Glasgow composite pain scale short-form (GCMPS-SF), university of Melbourne pain scale (UMPS), and Visual Analogue Scales (VAS) were used to measure pain. C-reactive protein (CRP) fluctuation was also investigated. These evaluations were completed before and 6, 24, 48, and 72 h postoperatively.ResultsInstrument shank-assisted OHE was less time-consuming than conventional OHE (p = 0.005), improved PIT by 30.7% (6.44 min for both pedicles, p = 0.014), and correlated strongly with TST (ρ = 0.862, p = 0.003 and ρ = 0.955, p = 0.000, respectively). The two method’s surgical step durations were also TST = 47.40 ± 9.9 vs. 34.70 ± 6.7 min, PIT = 20.96 ± 5.78 vs. 14.52 ± 3.73 min, SRT = 78.97 ± 69.10 vs. ShT = 20.39 ± 8.18 s (p = 0.035), ClpT = 50.66 ± 45.04 vs. 63.55 ± 37.15 s (p = 0.662), LigT = 12.82 ± 3.37 vs. 8.02 ± 3.11 min (p = 0.005), and CT = 16.40 ± 4.5 vs. 11.60 ± 2.5 min (p = 0.013), respectively. While both techniques inflicted pain on the animals, the novel approach resulted in a reduction of pain at T6 (GCMPS-SF, p = 0.015 and VAS, p = 0.002), T24 (UMPS, p = 0.003), and T48 (GCMPS-SF, p = 0.015 and UMPS, p = 0.050). Both methods exhibited a peak in CRP level after 24 h, which subsequently returned to baseline after 48 h. However, the shank-assisted method demonstrated a significantly lower reduction in CRP level at the 48-h compared to the other group (p = 0.032).ConclusionInstrument shank-assisted technique permitted ovarian removal without an assistant, less damage to animals and reducing its time when compared to a conventional technique, and resulting in an alternative that causes less surgical stress and fatigue. Further research with a larger population size is required to determine the serum CRP levels as an alternative pain biomarker.

Background: General anesthesia leads to different effects depending on the drugs used (hypnosis, analgesia, muscle relaxation). While there are validated methods for clinical monitoring and control of hypnosis and muscle relaxation in routine anesthesia, the assessment of analgesia is still mainly based on the interpretation of clinical vital parameters, such as heart rate, blood pressure, perspiration or intraoperative movements of the patient. The present clinical study investigated whether the use of a so-called nociception monitor to record the intraoperative need for analgesics is superior to the previous analysis of vital parameters. The analgesia nociception index (ANI; MDoloris, Lille, France) was used, which is one of several nociception monitors currently on the market for recording the sympathicovagal balance. In the case of the ANI, the measurement is based on the analysis of the heart rate variability (HRV) as a function of breathing. The index is given in the form of a dimensionless score between 0 and 100, where 0 stands for a lack of parasympathetic activity and 100 for a very strong parasympathetic activity. According to the manufacturer, a value between 50–70 under anesthesia corresponds to sufficient intraoperative analgesia. Methods: This was a clinical prospective randomized study in which 110 patients who underwent laparoscopic hysterectomy under balanced anesthesia using propofol, fentanyl and atracurium for induction and sevoflurane and fentanyl for anesthesia maintenance, were divided into two groups. In the intervention group (ANI group), during the operation analgesics were administered with the aid of the ANI monitor (bolus of 0.1 mg fentanyl if the ANI was < 50), whereas in the comparison group analgesics were administered according to previous clinical parameters (vital parameters, intraoperative defensive movements). The groups were then compared with respect to intraoperative fentanyl consumption (primary outcome), postoperative pain and opioid-induced side effects (measured by the numeric rating scale [NRS]) as well as patient satisfaction on postoperative day 3 (secondary outcome). Results: The observations showed a higher total intraoperative consumption of fentanyl in the intervention group, due to a significantly higher number of individual doses (0.54 vs. 0.44 mg, p < 0.001). With respect to the other observation points, there were hardly any differences between the groups, neither with respect to the pain score nor the side effects in the recovery room. At most there was a trend towards a slightly lower pain score at the first measurement point in the recovery room (NRS at 15 min). In the patient survey on the postoperative day 3, there was a difference with respect to the subjectively described reduction in vigilance in the ANI group, but not other side effects or overall satisfaction with the pain therapy. Conclusion: In this group of patients the additional use of the ANI monitor for intraoperative control of analgesia led to an increased consumption of fentanyl compared to the comparison group, without having an impact on the postoperative pain score, opioid-induced side effects or patient satisfaction. An optimization of pain therapy through intraoperative use of the ANI monitoring in hysterectomy patients under balanced anesthesia with sevoflurane and fentanyl could therefore not be proven. Transferability of the results to a much older and/or sicker patient collective remains questionable. [ABSTRACT FROM AUTHOR]

Abstract Background Mild to moderate CTS is the most common median nerve compression disease in middle-aged and elderly women, mainly manifested by hand numbness and pain. This paper analyzes the extracorporeal shock wave of patients with mild to moderate CTS after nerve mobilization. Methods The clinical data of 92 patients with CTS from June 2020 to June 2022 are analyzed and randomly divided into extracorporeal shock wave group (n = 47) and routine group (n = 45). The routine group undergoes nerve mobilization, and the extracorporeal shock wave group receives extracorporeal shock wave therapy on the basis of the routine group. The clinical efficacy, symptom improvement, pain score, median nerve electrophysiological examination results, upper limb symptom and function scores, and ADL scores before and after treatment are observed. The Spearman correlation coefficient is used to analyze the correlation between upper limb function and ADL score, and the incidence of complications after treatment is analyzed. Results The clinical efficacy, symptom improvement, pain score, median nerve electrophysiological examination results, upper limb symptom and function score, ADL score and the incidence of complications in the extracorporeal shock wave group are significantly better than those in the conventional group (P

BackgroundEquine pain scoring may be affected by the residual effect of anesthetic drugs.ObjectivesTo compare pain scores in the hours immediately following anesthetic recovery to baseline pre-anesthetic scores in equine patients undergoing surgical and non-surgical procedures.Study designClinical observational study.MethodsFifty adult horses undergoing anesthesia for surgical or non-surgical procedures were enrolled. Horses underwent pain scoring using the Composite Pain Score (CPS) and Equine Utrecht University Scale for Facial Assessment of Pain (EQUUS-FAP) prior to anesthesia (T0) and following anesthetic recovery to standing, every hour for 5 h (T1-T5). Data were analyzed using a generalized linear mixed effects model. A post-hoc Dunnett's test for multiple comparisons was performed for variables where an effect was detected.ResultsMean (95% confidence interval) CPS scores for T0-T5 were 1.6 (1.2–2.0), 6.8 (6.0–7.6), 5.1 (4.3–5.9), 4.3 (3.4–5.2), 3.7 (2.8–4.6), and 2.8 (2.0–3.6) and EQUUS-FAP scores were 0.6 (0.3–0.9), 3.0 (2.5–3.5), 1.9 (1.6–2.2), 1.1 (0.8–1.4), 0.6 (0.4–0.8), and 0.7 (0.4–1.0), respectively. For the CPS, scores greater than 5, and for the EQUUS-FAP scores greater than 3, are consistent with minor pain. There was no effect of type of procedure (surgical vs non-surgical) on CPS or EQUUS-FAP scores. There was an effect of time with CPS scores significantly greater than baseline at T1-T5 and EQUUS-FAP scores significantly greater than baseline at T1 and T2.Main limitationsDiscomfort caused by hoisting was not quantified and it was difficult to ascertain if this affected the results.ConclusionsPost-anesthetic pain scores may be influenced by the residual effect of anesthetic agents for as long as 5 h and 2 h for the CPS and EQUUS-FAP, respectively.

Simple Summary: Fatal injuries in Thoroughbred racehorses typically occur due to an accumulation of bone damage, however, detecting their impending onset can be difficult as there are often no overt signs. In other horse populations, facial grimacing has been shown to be associated with orthopaedic pain. This study, therefore, aimed to investigate facial expressions of Thoroughbred racehorses at the trot to identify if there were subtle signs of pain in mildly lame compared to non-lame horses. Two independent observers assessed 22 facial expression parameters using still photographs of the head from video-recorded trot-ups. There were few expressions associated with lameness except for more exposed whites of the eye in lame horses. Thus, facial pain scoring may not be adequate for the detection of subtle lameness in racehorses who work in a racing stable environment. Musculoskeletal injuries in racehorses are difficult to detect prior to catastrophic breakdown. Lameness is commonly attributed to orthopaedic pain in horses, therefore, subtle lameness may be a pre-clinical sign of injury and, if identified early, could allow for preventative intervention. Our objective was to determine if facial expressions could be used to detect mild lameness as an indicator of orthopaedic pain in 'fit to race' horses. The Horse Grimace Scale (HGS) and the facial expressions in ridden horses (FEReq), were used to score images (n = 380) of mildly lame (n = 21) and non-lame (n = 17) Thoroughbred horses by two independent observers. Using an Equinosis Lameness Locator®, the lameness status of each horse was determined according to published thresholds [forelimb lameness (>|14.5 mm|) and hindlimb lameness (>|7.5 mm|)]. Inter and intraobserver reliability were assessed using two-way random-effects models. Univariable associations between lameness and facial expression parameters were identified using logistic and linear regression. Interobserver reliability was moderate (κ 0.45; 95% CI 0.36, 0.55). Horses with moderate mouth strain (HGS) and tense and extended upper lip (FEReq) were less likely to be lame (p = 0.042 and p = 0.027, respectively). Exposed sclera was associated with lameness (p = 0.045). Higher orbital tightening (HGS) scores were associated with a lower degree of maximum head amplitude (HDmax) lameness (p = 0.044). Tension and moderate tension above the eye, for the HGS and FEReq scores, were associated with increasing amplitude of HDmax (p = 0.048 and p = 0.034, respectively). Inconsistent associations between lameness status and HGS and FEReq scores may limit the potential use of the facial expression for the prediction of mild orthopaedic pain during pre-race lameness examinations. More objective parameters associated with mild orthopaedic pain should be explored. [ABSTRACT FROM AUTHOR]

Objective: Lutetium-177 prostate-specific membrane antigen-617 is a novel alternative therapeutic option in metastatic castration-resistant prostate cancer, especially useful for patients who do not respond to standard therapy methods. The aim of this study was to define the efficacy and safety profile of lutetium-177 prostate-specific membrane antigen-617 treatment in a group of patients with metastatic castration-resistant prostate cancer. Materials and Methods: Study group included 34 men with metastatic castration-resistant prostate cancer (median, 69.6 ± 7.7 years) who were treated with lutetium-177 prostate-specific membrane antigen-617 therapy (22/34; 4 courses, 12/34; 2 courses). Patients were evaluated by physical examination, Eastern cooperative oncology group performance status, gallium-68 prostate-specific membrane antigen positron emission tomography/computed tomography, brief pain inventory-short form questionnaire, biochemical tests, and complete blood counts. Treatment response and adverse effects were examined by brief pain inventory scores, SUVmax values, biochemical tests, and complete blood counts. Independent variables were analyzed statistically (significance; P < .05). Results: The Eastern cooperative oncology group performance was grade 0 in 5/34 (14.7%), grade 1 in 25/34 (73.5%), and grade 2 in 4/34 (11.8%) patients. Distribution of patient numbers according to brief pain inventory scores (score: <1, scores: 1-4, and scores: 5-10) was 2, 10 and 22 at the beginning, 6, 16 and 12 after the second course, and 10, 10 and 2 after the fourth course of treatment, respectively. Serum prostate-specific antigen decreased in 15 of 22 patients (68%) (P < .05). Before and after the treatment, we found a substantial decrease in SUVmax values (22.3 vs. 11.8, P < .001) and brief pain inventory scores (score = 5; 22/34 pts vs. 0/22 pts). The counts of white blood cells (P < .05), hemoglobin (P < .05), and thrombocytes (P = .001) were all significantly lower at the conclusion of the therapy. The most important adverse events were severe leukopenia (1/34 pts; 2.29 × 10 3/µL) and thrombocytopenia (3/34 pts; 32 000, 36 000, 32 000 106/L). Conclusion: We found that lutetium-177 prostate-specific membrane antigen-617 therapy is a promising treatment method for metastatic castration-resistant prostate cancer patients who are unresponsive to conventional therapy, according to our biochemical, positron emission tomography/computed tomography, and pain score outcomes.
