Efficacy of local pain management strategies for patients undergoing anterior iliac crest bone harvesting: a systematic review.

Anterior Iliac crest bone harvesting (AICBH) is a common surgical procedure with applications in various medical specialties, but it is often accompanied by significant postoperative pain. Effective pain management is therefore essential for optimising patient outcomes. This systematic literature review aimed to evaluate the effectiveness of local donor site pain management interventions in AICBH procedures. It followed the Cochrane Handbook for Systematic Reviews of Interventions version 6.4 guidelines and adhered to the PRISMA 2020 statement for comprehensive and high-quality reporting. A comprehensive search was conducted across PubMed, Cochrane, and Embase to identify relevant studies. Inclusion criteria encompassed randomised controlled trials assessing pain management strategies in AICBH patients. The methodological quality of the included studies was assessed using the Jadad scale. Data extraction focused on medication types, administration modes, pain scores, and use of narcotics. Fourteen eligible studies were included. Methodological quality varied, with most studies demonstrating a low risk of bias. Medication types included amide and opioid groups, administered via single-shot injections or infusion systems. Results indicated that indwelling iliac crest catheters with bupivacaine showed significant postoperative reductions in pain scores and narcotics use compared with other techniques. The findings suggest that use of an indwelling catheter with bupivacaine is an effective pain management strategy for AICBH patients. However, heterogeneity among the studies and a lack of standardised methodologies pose limitations. Further homogeneous and standardised studies are therefore needed to strengthen the evidence base and inform clinical practice.

Time budgets and weight shifting as indicators of pain in hospitalized horses.

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.

Development and validation of a nomogram combining pain score with laboratory indicators for predicting persistent organ failure in acute pancreatitis: a retrospective cohort study.

Background: Acute 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. Objective: To develop and validate a nomogram that combines pain score with laboratory indicators for predicting POF in patients with AP. Methods: A 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. Results: There 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. Conclusion: The nomogram had a good performance in predicting POF in patients with AP and can be used to guide clinical decision-making.

[Traditional Chinese medicinal compress combined with herbal fumigation for acute epididymitis: A clinical observation].

OBJECTIVE: To observe the clinical efficacy of traditional Chinese medicinal (TCM) compress combined with herbal fumigation in the treatment of acute epididymitis. METHODS: This study included 74 cases of acute epididymitis treated in our hospital from December 2021 to December 2023. Using the single blind and random number methods, we divided the patients into a trial (n = 37) and a control group (n = 37). On the basis of routine medication with antibiotics, we treated the patients in the trial group by TCM compress combined with herbal fumigation and those in the control group by dyed pure water compress combined with herbal fumigation. At 3, 7 and 14 days of treatment, we obtained the pain scores and maximum epididymal diameters from the patients and compared them between the two groups before and after treatment. RESULTS: There were no statistically significant differences between the control and trial groups in the baseline pain scores (6.79 vs 6.85, P>0.05) and maximum epididymal diameters of the patients (ï¼»1.61 ± 0.39ï¼½ vs ï¼»1.59 ± 0.42ï¼½ cm, P>0.05) or in the pain scores after 3 days of treatment (4.63 ± 0.95 vs 4.45 ± 1.87, P>0.05). Compared with the controls, the patients of the trial group showed significantly lower pain scores (3.78 ±1.03 vs 1.02±0.36, P<0.05) and a higher overall effectiveness rate (75.68% vs 91.89%, P<0.05) at 7 days, and markedly shorter maximum epididymal diameters at 3 days (ï¼»1.45 ± 0.38ï¼½ vs ï¼»1.23 ± 0.72ï¼½ cm, P<0.05) and 7 days (ï¼»1.21 ± 0.29ï¼½ vs ï¼»0.98 ± 0.15ï¼½ cm, P<0.05). No statistically significant differences were observed between the control and trial groups in the pain scores (0.79 ± 1.12 vs 0.67 ± 0.86, P>0.05), maximum epididymal diameters (ï¼»0.94 ± 0.33ï¼½ vs ï¼»0.92 ± 0.21ï¼½ cm, P>0.05) or overall effectiveness rate (91.89% vs 97.30%, P>0.05) after 14 days of treatment. CONCLUSION: On the basis of routine medication with antibiotics, TCM compress combined with herbal fumigation can effectively relieve pain, reduce local swelling, accelerate recovery and shorten the course of treatment in patients with acute epididymitis, and is therefore worthy of clinical promotion and application.

Application of drainage strategy with bi-pigtail catheters in patients undergoing lobectomy by uniportal video-assisted thoracic surgery.

Background: There are no standard guidelines regarding the number and size of chest tubes that should be selected after thoracic surgery. This study aimed to evaluate the effects of adopting a drainage strategy with bi-pigtail catheters (BPCs) on patients undergoing lobectomy by uniportal video-assisted thoracic surgery (VATS). Methods: A retrospective study was performed of patients undergoing uniportal lobectomy at the Department of Thoracic Surgery of the Cancer Hospital of Dalian University of Technology between August 2021 and August 2022. The patients were divided into the following two groups according to the drainage strategy adopted: (I) a traditional chest tube (TCT) group; and (II) a BPC group. The outcomes measured included postoperative complications, as measured by the Clavien-Dindo method, and the visual analogue scale (VAS) pain scores of the patients after surgery. Results: In total, 868 patients underwent lung resection during the study period, after exclusion, the data of 470 patients who underwent uniport lobectomy were reviewed (235 in the TCT group, and 235 in the BPC group). There were no statistically significant differences between the two groups in terms of baseline data (P>0.05). The incidence of postoperative complications (7.7% vs. 19.1%) and postoperative VAS pain scores at 7-24 hours (3.3±1.0 vs. 3.7±1.5) and 25-48 hours (3.1±0.8 vs. 3.6±1.5) were significantly lower in the BPC group than the TCT group (all P<0.001). Additionally, the postoperative length of stay (4.6±1.5 vs. 5.4±4.5 days) and the collapse rate of the residual lung (19.2%±9.1% vs. 20.9%±9.6%) of the BPC group were better than those of the TCT group (P<0.05). The results of univariable and multivariable analyses showed that a drainage strategy with a TCT was an independent risk factor for decreased postoperative complications, and reduced moderate or severe pain scores at 7-24 and 25-48 hours after surgery. Conclusions: Our drainage strategy with BPCs decreased the incidence of postoperative complications and alleviated the postoperative pain of patients undergoing lobectomy by uniportal VATS and is safe and feasible.

Gel instillation sonohysterography (GIS) using Endosgel versus ExEmgel, comparison of pain and image quality and cost benefit analysis: A double blind randomised controlled trial. GISPAIN trial.

INTRODUCTION: Pain experience, physical reaction, image quality and adverse events during Gel Instillation Sonohysterography (GIS) can differ using gels with different compositions. As a result, patient satisfaction can also be affected. The effect of two instillation gels, Endosgel versus ExEmgel, using both the Visual Analogue Scale (VAS) and a Continuous Pain Score Meter (CPSM) was therefore compared. METHODS: This single centre double blind randomised controlled trial included 80 women planned for outpatient GIS, diagnosed with abnormal intrauterine bleeding or fertility disorders and suspicion on an intrauterine abnormality. Patients were randomly allocated to the instillation of Endosgel containing chlorhexidine or ExEmgel without chlorhexidine. Primary outcome was reported pain during the procedure using VAS. Secondary outcomes included pain score measured using CPSM, satisfaction to the procedure and preference at 3 weeks and 3 months after the procedure and image quality. A cost benefit analysis was also performed. RESULTS: The reported median VAS concerning pain during gel instillation was comparable in the Endosgel and ExEmgel group, 2.50 (IQR 0.00-5.00) and 2.00 (IQR 0.00-5.75) respectively (p = 0.69). The median VAS of the entire procedure was also similar: both 2.00 (IQR 0.00-5.00) (p = 0.86). CPSM-scores were not significantly different either. Both groups were similar in image quality (p = 0.83) and patient's satisfaction (p = 0.36). CONCLUSION: Concerning the pain experienced during a GIS procedure and patients' satisfaction, the ExEmgel was not proven to be superior to the Endosgel. Our advice is to use the gel that is available at the lowest costs, as the image quality is the same for both Endosgel and ExEmgel.

Comparison of Butorphanol, Methadone, and Pethidine in Combination with Alfaxalone for Premedication in Isoflurane-Anesthetized Cats Undergoing Ovariectomy.

The aim of this study was to compare three different anesthetic protocols administered intramuscularly (IM) in cats undergoing elective ovariectomy, while evaluating the quality of sedation, antinociceptive, isoflurane-sparing effect, and analgesia in the intra-operative and post-operative phases. A total of 71 female cats were sedated IM with alfaxalone (3 mg/kg) combined with either butorphanol (0.3 mg/kg), methadone (0.3 mg/kg), or pethidine (5 mg/kg). During surgery, vital parameters were constantly monitored; at the end of the procedure, the quality of recovery was assessed through a specific form and each cat was scored for perceived pain using the UNESP-Botucatu scale for 5 days, and rescue analgesia was provided with buprenorphine IM when indicated. Moreover, differences between two different post-operative resting regimens (hospital kennels vs. home) were also assessed. A significant difference emerged for the amount of IM dexmedetomidine required to achieve an adequate level of sedation for intravenous catheterization, highlighting a greater need in the pethidine group (p = 0.021). There was no significant difference between opioid groups for the requirement of intra-operative rescue analgesia, and the clinical parameters were kept within physiological ranges regardless of the opioid used in premedication. Lastly, differences between the UNESP-Botucatu scores were detected from day 3 to day 5 post-operatively, with lower scores in cats with home resting regimens compared to the hospitalized animals, likely due to the presence of an unfamiliar condition and the absence of a cat-friendly environment.

Intraoperative cryoanalgesia on reducing post-tonsillectomy pain scales: a meta-analysis of randomized controlled trials.

OBJECTIVE: To assess the effect of intraoperative cryoanalgesia on subjective pain scores of patients after tonsillectomy. METHODS: A systematic review of PubMED, Web of Science, EMBASE was performed using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) standards. For the first time, we included and quantitative synthesized English-language randomized controlled trials (RCT) evaluating patients of all age groups with benign pathology who underwent tonsillectomy with intraoperative cryoanalgesia versus without. RESULTS: A total of 835 publications were identified, and 7 articles with 463 participants met our criteria were selected for meta-analysis. The standard mean difference for overall subjective pain score, subjective pain scores at postoperation Day1 (POD1), POD7 were -1.44 with 95% confidence interval (CI) [-2.17, -0.72], P = .0001; -1.20 with 95% CI [-1.89, -0.50], P = .0007; -0.90 with 95% CI [-1.46, -0.35], P = .001 respectively, both in favor of cryoanalgesia. Nevertheless, subgroup analysis by surgical technique showed no robust effect between hot technique and "relative" hot technique on overall pain: (-1.72, 95% CI [-2.71, -0.73]) vs. (-1.06, 95% CI [-2.20, 0.07]), p=.39; on POD1: (-1.56, 95% CI [-2.78, -0.33]) vs. (-0.97, 95% CI [-1.83, -0.11]), p=.39; and on POD7 (-1.11, 95% CI [-1.81, -0.40]) vs. (-0.89, 95% CI [-2.02, 0.25]), p=.13. The standard mean difference for postoperative secondary bleeding rate was 1.29 with 95% CI 0.37,4.52], p = .06, no difference in 2 groups. CONCLUSION: Limited evidence suggests that intraoperative cryoanalgesia during tonsillectomy leads to lower subjective pain score on overall, POD1 and POD7 without differences on post-operation bleeding rate.

Characteristics and predictors of pain among women who underwent cesarean section in Fiji.

Aim: To identify the characteristics and predictors of post cesarean section (CS) pain among women.Materials & methods: This quantitative study was conducted at Labasa hospital in Fiji over a 6-month period. A total of 312 mothers who received spinal, epidural and general anesthesia were included. Their pain score was assessed using the visual analogue scale 24 h postoperatively.Results: 70.8% women had either moderate or severe pain on the visual analogue scale. About 41.3% women expressed dissatisfaction with their pain management and 70.5% women had difficulties in performing activities due to pain. Lower parity was noted to be a positive predictor of pain among women undergoing CS.Conclusion: Adequate pain management for post-CS patient at Labasa hospital is lacking.

Pain & pain control methods after surgical birth in Labasa, FijiWhat is the study about? This study looked at what affects pain in women after delivering a baby through surgery, also known as surgical birth or cesarean section (CS), at Labasa Hospital in Fiji. Over 6 months, 312 mothers who had surgical births with different types of pain-reducing medicines took part in this study. Their pain was checked 24 h after surgery using a pain scale.What were the results? The results showed that 70.8% of women felt moderate to severe pain after their surgical birth. In addition, 41.3% of the women were not happy with their pain control, and 70.5% had difficulties doing their daily activities because of the pain. The study also found that first-time mothers were more likely to feel more pain after their surgical birth.What do the results mean? The key point of the study is that many women at Labasa Hospital are not getting enough pain relief after their surgical birth, especially first-time mothers. This shows there is a need to improve pain control methods for these patients. A better pain control could help these mothers get better more comfortably and feel more satisfied with their care.

Kynurenine Pathway Dysregulation and Pain Perception in Acute Pancreatitis: Has the Connection Unraveled?

AIM: Tryptophan (TRP), an essential amino acid, undergoes catabolism through various pathways. Notably, the kynurenine pathway (KP), constituting one of these pathways, exhibits a unidirectional impact on immune response and energy metabolism. Nonetheless, its influence on pain sensation is characterized by biphasic dynamics. This study aims to scrutinize the influence of the KP pathway on pain sensation, particularly within the context of pancreatic inflammation. METHODS: Our prospective case-control study involved individuals diagnosed with acute pancreatitis and a control group matched for gender and age. The patient cohort was subsequently subdivided into severe and non-severe subgroups. To assess metabolites within KP, two blood samples were collected from the patient cohort, one at the time of diagnosis and another during the recovery phase. Furthermore, for pain quantification, daily pain scores utilizing the Visual Analog Scale (VAS) were extracted from the patients' medical records. RESULTS: The study incorporated 30 patients along with an equivalent number of controls. A noticeable distinction was evident between the patient and control groups, characterized by an increase in kynurenine levels and a decrease in the tryptophan/kynurenine ratio. Throughout the process of disease recovery, a uniform decrease was observed in all KP metabolites, excluding 3-Hydroxykynurenine. Elevated levels of Kynurenic acid (KYNA) were correlated with increased pain scores. Critically, no apparent distinctions in KP metabolites were discerned concerning pain severity in patients with comorbidities characterized by neural involvement. CONCLUSION: Based on our results, the kynurenine pathway (KP) is activated in instances of acute pancreatitis. Elevated levels of KYNA were found to be associated with heightened pain scores. The operative stages within the KP responsible for pain modulation are impaired in cases characterized by neuropathy-induced pain sensation.

Effectiveness of low-level laser therapy in reducing pain score and healing time of recurrent aphthous stomatitis: a systematic review and meta-analysis.

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.

Combined impact of local anaesthetic infiltration through wound catheter and epidural analgesia following surgical hepatectomy: a meta-analysis.

Introduction: A meta-analysis was performed to examine the effects of wound catheter (WC) local anaesthetic infiltration (LAI) and epidural analgesia (EA) in open hepatectomy (OH). Material and methods: A systematic literature review was performed, which found 350 subjects with OH at the baseline of the studies; 159 of them were treated with WC local anaesthetic infiltration, and 191 used EA. Results: WC LAI substantially reduced the functional recovery time (MD = -0.64; 95% CI, -1.02 to -0.26, p < 0.001) and increased the pain score on the second postoperative day (MD = 0.25; 95% CI: 0.10-0.40, p < 0.001) compared to EA in OH patients. WC LAI did not vary from EA in OH patients in second postoperative opiate use (MD = -14.86; 95% CI: -32.88 to 3.16, p = 0.11) or overall complication rate (OR = 0.66; 95% CI: 0.41-1.04, p = 0.07). Conclusions: WC LAI showed a non-significant difference in opiate consumption on the second postoperative day and in the overall complication rate, compared with EA, but it showed a lower functional recovery time and higher pain score.

Assessing the Knowledge, Attitude, and Practice of Orthopedicians for Pain Management by Multimodal Approach: A Prospective, Cross-Sectional, and Observational Survey.

BACKGROUND: The routine use of multimodal analgesic modality results in lower pain scores with minimum side effects and opioid utilization. MATERIALS AND METHODS:  A prospective, cross-sectional, observational study was conducted among orthopedicians practicing across India to assess the professional opinions on using analgesics to manage orthopedic pain effectively. RESULTS:  A total of 530 orthopedicians participated in this survey. Over 50% of the participants responded that tramadol with or without paracetamol was the choice of therapy for acute pain. Nearly 50% of the participants mentioned that multimodal interventions can sometimes help to manage pain. A total of 55.6% of participants mentioned that using Non-steroidal anti-inflammatory drugs was the most common in their clinical practice, while 25.7% of participants mentioned that they used tramadol more commonly in their clinical practice. As per clinical efficacy ranking, the combination of tramadol plus paracetamol (44.3%) was ranked first among analgesic combinations, followed by aceclofenac plus paracetamol (40.0%). The severity of pain (62.6%) followed by age (60.6%) and duration of therapy (52.6%) were the most common factors that should be considered while prescribing tramadol plus paracetamol combination. Gastrointestinal and renal are reported as the most common safety concerns encountered with analgesics. CONCLUSION:  The combination of tramadol and paracetamol was identified as the most preferred choice of analgesics for prolonged orthopedic pain management.

A Study of Comparison of Outcomes of Submucous Diathermy, Coblation and Micro-debrider Assisted Inferior Turbinoplasty in Patients Having Inferior Turbinate Hypertrophy.

The cause of nasal obstruction in most of the patients is either nasal septal deviation or turbinate hypertrophy owing to vasomotor or perennial allergic rhinitis. Most cases of hypertrophic turbinate are usually mild and respond to antihistamine therapy, local decongestions, or allergy desensitization; however, surgery is required in some cases. In our present study, three surgical methods were used for inferior turbinoplasty i.e. Sub-mucous Diathermy, Coblation and Micro-debrider and patients were divided randomly in these groups. The efficacy and outcomes of these methods was compared on the basis of subjective and objective relief of symptoms and their safety, recurrence and post-operative morbidity. Out of 45 patients, highest number of patients belonged to 20-40 years of age with the mean age of 28.7 years and male female ration 0.78:1. All the patients were evaluated on the basis of preoperative Endoscopic grading of inferior turbinate and SNOT22 symptom scores (Sino Nasal Outcome Test 22), intra-operative timing and bleeding and post-operative pain, crusting, SNOT22 scores (Sino Nasal Outcome Test 22) and Endoscopic grading improvement in inferior turbinate. On comparing all the above methods, we found that Coblation and Micro- debrider were more or less equally effective and better than Sub-mucous diathermy for inferior turbinoplasty. Submucous diathermy has least benefits, still most commonly used method because of its simplicity, conventionality and least cost factor while other two methods need capital investment and higher learning curve of the surgeon.

Analgesic utility of automatic lancing device for heel prick in neonates: a systematic review and meta-analysis.

Background: This systematic review and meta-analysis assessed the benefits of an automatic lancing device compared with a manual lancet or a hypodermic needle in neonates. Materials & methods: We followed the Cochrane Handbook methodology, used the RoB-2 tool for risk of bias assessment, RevMan 4.1 for meta-analysis and GRADE framework for certainty assessment. We searched the databases and gray literature on 15 November 2023. Results: Six eligible studies enrolling 539 neonates were included. An automatic lancing device reduced pain scores during and after heel prick, sampling time and the need for repeat puncture. The certainty of evidence was very low to moderate. Conclusion: An automatic lancing device is preferred for heel pricks in neonates, given less pain and higher efficiency.PROSPERO registration number: CRD42023483189.

What is this article about? The heel prick is a common painful procedure in neonates. It is performed either with a hypodermic needle or a lancet (manual or automatic lancing device). Few studies have shown that an automatic lancing device, with depth regulation, causes less pain. We reviewed the available literature to assess the benefits and harms of different sampling methods.What were the results? We found six studies comparing these interventions for heel prick in neonates. There was a significant reduction in pain score, sampling time and need for repeated pricks when using an automatic lancing device.What do the results of the study mean? The automatic lancing device causes less pain (safer) and reduces the time required for sampling and repeated pricks (more effective) when used for heel pricks in neonates.

Postoperative pain following laser fistula closure versus ligation of the intersphincteric fistula tract: A prospective double-blinded randomized controlled trial.

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.

Correlation Between Blood Levels of Cysteine Protease Caspase-1 (Casp1) and Pain Scores (NRS) Post-surgery: A Prospective Randomized Study of Patients With Cholelithiasis.

BACKGROUND/AIM: Cysteine protease caspase-1 (Casp1) plays a crucial role in the conversion of pro-cytokines to active cytokines (CYTs). The purpose of this work was to determine Casp1 blood levels in a cohort of 114 cholecystectomy patients and assess their association with other CYTs and numeric rating scale (NRS) pain scores, postoperatively. PATIENTS AND METHODS: Blood levels of Casp1 and seven CYTs (IL-18, IL-18BP, IL-1ra, IL-6, IL-10, IL-1ß, and IL-8) were measured at three time points; before operation, immediately after operation, and six hours after operation in 114 patients with cholelithiasis (Chole). RESULTS: Casp1 blood levels correlated with NRS pain scores at 24 h following surgery (p=0.016). In addition, Casp1 blood levels correlated significantly to IL-18 blood levels (p<0.001). CONCLUSION: This is the first report to evaluate Casp1 blood levels in Chole patients in correlation with other CYTs. The findings confirm a significant correlation between Casp1 blood levels and NRS pain scores. Moreover, this study provides initial evidence suggesting that inhibition of the activity of Casp1 may reduce postsurgical acute phase immune response possibly through the Casp1/pro-Il-18 pathway.

Evaluating the Efficacy of a Peripheral Nerve Simulator-Guided Brachial Plexus Block in Rabbits Undergoing Orthopaedic Surgery Compared to Systemic Analgesia.

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.

Feasibility of utilizing mediastinal drains alone following esophageal cancer surgery: a retrospective study.

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.

Neurorehabilitation strategies: Assessing the impact on postoperative psychological state, pain, and complications in trigeminal neuralgia.

BACKGROUND: Trigeminal neuralgia is a difficult clinical situation marked by excruciating pain that requires efficient postoperative measures. In patients with trigeminal neuralgia, this study sought to investigate the effects of ongoing rehabilitation intervention on postoperative outcomes, including psychological state, pain, and complications. The aim was to provide new perspectives and treatment strategies for the management of this crippling illness. NEW METHOD: Between January 2021 and December 2022, 120 patients receiving treatment for trigeminal neuralgia were randomized to either the observation or control groups. The observation group received a continuous and comprehensive rehabilitation intervention that included elements of the control group's regimen, while the control group received standard health education and dietary guidance interventions through the use of a digital table method. The assessment of pain scales (VAS), self-rating depression scales (SDS), self-rating anxiety scales (SAS), and complication rates were all part of the postoperative follow-up. RESULTS: At seven days following surgery, there were no appreciable variations in the observation and control groups' VAS, SAS, and SDS scores (P > 0.05). Nevertheless, the observation group showed significantly lower VAS and SAS scores than the control group at 6 months and 1 year following surgery (P < 0.05). The observation group's SDS score was significantly lower than the control group's one year after surgery (P < 0.001). In comparison to the control group, the observation group also showed a lower overall complication rate (P < 0.05), especially in the cases of facial herpes and vertigo. COMPARISON WITH EXISTING METHODS: Our ongoing, all-encompassing rehabilitation approach demonstrated better results than current approaches in terms of long-lasting pain alleviation, enhanced mental health, and lower rates of complications in patients with trigeminal neuralgia following surgery. This implies that, in comparison to traditional methods, incorporating rehabilitation strategies may provide greater therapeutic benefits. CONCLUSION: Continuous comprehensive rehabilitation intervention can effectively reduce the degree of postoperative pain in patients with trigeminal neuralgia, help to regulate their psychological state, and reduce the occurrence of complications, which has certain clinical application value.
