Intraoperative intravenous versus periarticular injection of glucocorticoids in improving clinical outcomes after total knee arthroplasty: A prospective, randomized and controlled study.

BACKGROUND: Glucocorticoids have been widely used in perioperative period for postoperative pain relief after total knee arthroplasty (TKA). However, the optimal administration protocols of glucocorticoids remain controversial. This study aims to compare the efficacy of glucocorticoids between intravenous and periarticular injection on clinical outcomes. METHODS: A total of 114 patients were randomly assigned to intravenous (IV) group (n = 57) and periarticular injection (PI) group (n = 57). The IV group received 10 mg dexamethasone intravenously and the PI group received periarticular injection of 10 mg dexamethasone during the procedure. The clinical outcomes were assessed using visual analogue scale (VAS), knee society score (KSS), range of motion (ROM), knee swelling, inflammation markers and complications after TKA. RESULTS: The VAS score during walking at 2nd day postoperatively was lower in the PI group compared with the IV group (2.08 ± 1.45 vs 2.73 ± 1.69, p = .039), and there was no significant difference at the other time points of VAS score in two groups. The inflammation markers, knee swelling, knee ROM and KSS score were not statistically different. Vomiting and other complications occurrence were not significantly different between the two groups. CONCLUSIONS: Intraoperative periarticular injection of glucocorticoids has similar analgesic effect compared to intravenous in the postoperative period following TKA and may be even more effective on the second postoperative day. In addition, periarticular injection of glucocorticoids does not impose an excess risk or complication on patients.

Prevention of persistent pain with lidocaine infusions in breast cancer surgery (PLAN): study protocol for a multicenter randomized controlled trial.

BACKGROUND: Persistent pain is a common yet debilitating complication after breast cancer surgery. Given the pervasive effects of this pain disorder on the patient and healthcare system, post-mastectomy pain syndrome (PMPS) is becoming a larger population health problem, especially as the prognosis and survivorship of breast cancer increases. Interventions that prevent persistent pain after breast surgery are needed to improve the quality of life of breast cancer survivors. An intraoperative intravenous lidocaine infusion has emerged as a potential intervention to decrease the incidence of PMPS. We aim to determine the definitive effects of this intervention in patients undergoing breast cancer surgery. METHODS: PLAN will be a multicenter, parallel-group, blinded, 1:1 randomized, placebo-controlled trial of 1,602 patients undergoing breast cancer surgery. Adult patients scheduled for a lumpectomy or mastectomy will be randomized to receive an intravenous 2% lidocaine bolus of 1.5 mg/kg with induction of anesthesia, followed by a 2.0 mg/kg/h infusion until the end of surgery, or placebo solution (normal saline) at the same volume. The primary outcome will be the incidence of persistent pain at 3 months. Secondary outcomes include the incidence of pain and opioid consumption at 1 h, 1-3 days, and 12 months after surgery, as well as emotional, physical, and functional parameters, and cost-effectiveness. DISCUSSION: This trial aims to provide definitive evidence on an intervention that could potentially prevent persistent pain after breast cancer surgery. If this trial is successful, lidocaine infusion would be integrated as standard of care in breast cancer management. This inexpensive, widely available, and easily administered intervention has the potential to reduce pain and suffering in an already afflicted patient population, decrease the substantial costs of chronic pain management, potentially decrease opioid use, and improve the quality of life in patients. TRIAL REGISTRATION: This trial has been registered on clinicaltrials.gov (NCT04874038, Dr. James Khan. Date of registration: May 5, 2021).

Laser hemorrhoidoplasty vs. rubber band ligation: a randomized trial comparing 2 mini-invasive treatment for grade II hemorrhoids.

PURPOSE: As a minimally invasive procedure, laser hemorrhoidoplasty (LHP) can not only relieve the symptoms of hemorrhoids, but also protect the anal cushion structure. This study aimed to investigate the clinical efficacy of LHP in the treatment of grade II hemorrhoids. METHODS: A total of 70 patients with grade II hemorrhoids were randomly assigned to receive LHP or Rubber Band Ligation (RBL) (n = 35 per group) in 2019 from a single center. The postoperative pain, bleeding, feeling of anal distension(local falling, swelling, foreign body sensation, stool) and postoperative recurrence rate were compared between the two groups. RESULTS: The postoperative pain, bleeding, and feeling of anal distension in the LHP group were improved significantly as compared with the RBL group within 2 weeks after surgery (P < 0.01). Both methods can relieve the symptoms of grade II hemorrhoids. There was no difference in the recurrence rate between the two groups at 1 year after surgery (P > 0.05). The patients in LHP group took less time to return to normal activities (P < 0.001). CONCLUSIONS: As a minimally invasive treatment, LHP is easy and not traumatic and results in mild postoperative pain and few complications. It is an ideal choice for grade II hemorrhoids.

A comparison of port-site infiltration with bupivacaine alone vs. bupivacaine plus dexemedetomidine after diagnostic staging laparoscopy.

Objectives: To compare the effects of bupivacaine alone and in combination with dexmedetomidine following staging laparoscopies. METHODS: This triple-blinded, prospective study was conducted from June to September 2021 at a tertiary care cancer hospital in Lahore, Pakistan, and comprised adult patients having American Society of Anaesthesiologists grade I-III, weighing >30kg and undergoing diagnostic staging laparoscopy. The subjects were randomised into two equal groups. Group A received 6ml of 2mg/kg bupivacaine at each of the four laparoscopic port sites before skin closure, while group B additionally received 2µg/kg dexmedetomidine. The presence and severity of pain were recorded and assessed at 15 min, 1, 2 and 4 hours as well as at the time of discharge from the post-anaesthesia care unit. The time to first request for rescue analgesia, total morphine consumption, and the occurrence of any side effects during their stay were also recorded. Data was analysed using SPSS 23. RESULTS: Of the 30 patients, 15(50%) were in group A; 10(66.6%) males and 5(33.3%) females with mean age 43.27±7.59 years. There were 15(50%) patients in group B; 12(80%) males and 3(20%) females with mean age 41.36±12.42 years (p>0.05). Of the total, 29(96.66%) patients were classified as American Society of Anaesthesiologists grade II, and 1(3.33%) patient in group A was grade III. There was no significant difference between the groups in any of the outcome measures assessed (p>0.05), and none of the patients experienced any side effect throughout the post-operative stay. CONCLUSIONS: The combination of dexmedetomidine and bupivacaine had no significant improvement in pain relief compared to bupivacaine alone.

Effect of cognitive behavioral therapy on pain, knee function, and psychological status in patients after primary total knee arthroplasty: a systematic review and meta-analysis.

OBJECTIVE: The clinical efficacy of cognitive behavioral therapy (CBT) after Total knee arthroplasty (TKA) is still controversial, and the purpose of this meta-analysis was to evaluate the effect of CBT on pain, knee function, and psychological status of patients after TKA. METHODS: We systematically searched electronic databases such as CNKI, CBM, VIP, PubMed, Cochrane Library, and EMBASE for randomized controlled studies up to February 30, 2023. Screening against inclusion criteria to select valid studies and extract data. The quality of included studies was evaluated by the Cochrane Collaboration risk-of-bias 2 (RoB 2) tool for randomized trials. Statistical analysis of the data from this study was carried out using Stata 15.1 software. RESULTS: Finally, our meta-analysis incorporated seven randomized controlled studies of high quality, including 608 patients. The findings of the meta-analysis demonstrated a noteworthy decrease in kinesiophobia levels during the early postoperative phase in the CBT group as compared to the usual care group (WMD = -6.35, 95% CI: -7.98 to -4.72, Z = 7.64, P < 0.001). However, no statistically significant difference between the CBT and usual care groups in terms of postoperative pain as well as knee function. CONCLUSION: CBT may effectively reduce the level of kinesiophobia in the short term after TKA, but did not significantly relieve knee pain or improve knee function.

Sex moderates the association between quantitative sensory testing and acute and chronic pain after total knee/hip arthroplasty.

OBJECTIVES: Acute postsurgical pain (APSP) may persist over time and become chronic. Research on predictors for APSP and chronic postsurgical pain (CPSP) has produced inconsistent results. This observational study aimed to analyze psychological and psychophysical variables associated with APSP and CPSP after total knee or hip arthroplasty, and to explore the role of sex. METHODS: Assessments were conducted before surgery, 48 h, and 3 months postsurgery, including questionnaires (sociodemographic, pain related, and psychological) and quantitative sensory testing (QST). Hierarchical linear regression models analyzed potential predictors of APSP and CPSP, and moderation analyses evaluated the role of sex. RESULTS: The study included 63 participants undergoing total knee (34, 54%) or hip (29, 46%) arthroplasty. Thirty-one (49.2%) were female and 32 (50.8%) were male. APSP (48 h) was associated with impaired conditioned pain modulation (CPM) (ß = 0.301, p = 0.019). CPSP (3 months) was associated with being female (ß = 0.282, p = 0.029), longer presurgical pain duration (ß = 0.353, p = 0.006), knee arthroplasty (ß = -0.312, p = 0.015), higher APSP intensity (ß = 373, p = 0.004), and impaired CPM (ß = 0.126, p = 0.004). In multivariate analysis, these clinical variables were significant predictors of CPSP, unlike sex, and CPM (adj. R 2 = 0.349). Moderation analyses showed that wind-up ratio (WUR) was a significant predictor of APSP in men (WUR × sex: b = -1.373, p = 0.046) and CPM was a significant predictor of CPSP in women (CPM × sex: b = 1.625, p = 0.016). CONCLUSIONS: Specific QST parameters could identify patients at risk for high-intensity APSP and CPSP, with sex as a moderator. This has important clinical implications for patient care, paving the way for developing tailored preventive pain management strategies.

Perioperative pain optimization in the age of the opioid epidemic.

PURPOSE OF REVIEW: The opioid epidemic remains a constant and increasing threat to our society with overdoses and overdose deaths rising significantly during the COVID-19 pandemic. Growing evidence suggests a link between perioperative opioid use, postoperative opioid prescribing, and the development of opioid use disorder (OUD). As a result, strategies to better optimize pain management during the perioperative period are urgently needed. The purpose of this review is to summarize the most recent multimodal analgesia (MMA) recommendations, summarize evidence for efficacy surrounding the increased utilization of Enhanced Recovery After Surgery (ERAS) protocols, and discuss the implications for rising use of buprenorphine for OUD patients who present for surgery. In addition, this review will explore opportunities to expand our treatment of complex patients via transitional pain services. RECENT FINDINGS: There is ample evidence to support the benefits of MMA. However, optimal drug combinations remain understudied, presenting a target area for future research. ERAS protocols provide a more systematic and targeted approach for implementing MMA. ERAS protocols also allow for a more comprehensive approach to perioperative pain management by necessitating the involvement of surgical specialists. Increasingly, OUD patients taking buprenorphine are presenting for surgery. Recent guidance from a multisociety OUD working group recommends that buprenorphine not be routinely discontinued or tapered perioperatively. Lastly, there is emerging evidence to justify the use of transitional pain services for more comprehensive treatment of complex patients, like those with chronic pain, preoperative opioid tolerance, or substance use disorder. SUMMARY: Perioperative physicians must be aware of the impact of the opioid epidemic and explore methods like MMA techniques, ERAS protocols, and transitional pain services to improve the perioperative pain experience and decrease the risks of opioid-related harm.

Does psychological distress predict risk of orthopaedic surgery and postoperative opioid prescribing in patients with hip pain? A retrospective study.

BACKGROUND: Clinicians and public health professionals have allocated resources to curb opioid over-prescription and address psychological needs among patients with musculoskeletal pain. However, associations between psychological distress, risk of surgery, and opioid prescribing among those with hip pathologies remain unclear. METHODS: Using a retrospective cohort study design, we identified patients that were evaluated for hip pain from January 13, 2020 to October 27, 2021. Patients' surgical histories and postoperative opioid prescriptions were extracted via chart review. Risk of hip surgery within one year of evaluation was analyzed using multivariable logistic regression. Multivariable linear regression was employed to predict average morphine milligram equivalents (MME) per day of opioid prescriptions within the first 30 days after surgery. Candidate predictors included age, gender, race, ethnicity, employment, insurance type, hip function and quality of life on the International Hip Outcome Tool (iHOT-12), and psychological distress phenotype using the OSPRO Yellow Flag (OSPRO-YF) Assessment Tool. RESULTS: Of the 672 patients, n = 350 (52.1%) underwent orthopaedic surgery for hip pain. In multivariable analysis, younger patients, those with TRICARE/other government insurance, and those with a high psychological distress phenotype had higher odds of surgery. After adding iHOT-12 scores, younger patients and lower iHOT-12 scores were associated with higher odds of surgery, while Black/African American patients had lower odds of surgery. In multivariable analysis of average MME, patients with periacetabular osteotomy (PAO) received opioid prescriptions with significantly higher average MME than those with other procedures, and surgery type was the only significant predictor. Post-hoc analysis excluding PAO found higher average MME for patients undergoing hip arthroscopy (compared to arthroplasty or other non-PAO procedures) and significantly lower average MME for patients with public insurance (Medicare/Medicaid) compared to those with private insurance. Among those only undergoing arthroscopy, older age and having public insurance were associated with opioid prescriptions with lower average MME. Neither iHOT-12 scores nor OSPRO-YF phenotype assignment were significant predictors of postoperative mean MME. CONCLUSIONS: Psychological distress characteristics are modifiable targets for rehabilitation programs, but their use as prognostic factors for risk of orthopaedic surgery and opioid prescribing in patients with hip pain appears limited when considered alongside other commonly collected clinical information such as age, insurance, type of surgery pursued, and iHOT-12 scores.

Fixed-time interval vs on-demand oral analgesia after vaginal delivery: a randomized controlled trial.

BACKGROUND: Scheduled administration of analgesics was proven superior to on-demand dosing following cesarean deliveries. However, this protocol was not compared after vaginal delivery. OBJECTIVE: To compare the efficacy of a fixed- vs on-demand analgesic protocol for the management of pain in the first 24 hours after a vaginal delivery. STUDY DESIGN: This randomized, prospective, controlled trial was conducted at a single tertiary medical center between June 1, 2020 and June 30, 2022. Vaginally delivered patients were randomly assigned to receive oral analgesics (paracetamol 1 g + ibuprofen 400 mg) either every 6 hours for the first 24 hours postpartum (scheduled analgesia group) or as needed (on-demand group). Pain level during the first 24 hours postdelivery was measured using a 10-point visual analog scale. RESULTS: A total of 200 patients were randomized 1:1 to the 2 cohorts. Baseline and delivery characteristics, including oxytocin augmentation, epidural anesthesia, episiotomy rate, and neonatal birthweight, were comparable between groups. Patients in the scheduled group received more paracetamol and ibuprofen doses in the first 24 hours (2.9±1.3 and 2.9±1.2 doses vs 0.8±1.1 and 0.7±1.1 doses, respectively; P<.001). Pain score was comparable between study groups (5.31±1.92 vs 5.29±1.67; P=.626) even after subanalysis for primiparity, episiotomy, and vacuum-assisted delivery (P>.05). However, patients on a fixed treatment schedule were more likely to breastfeed their baby (98% vs 88%; P=.006) as than those receiving treatment on demand. In addition, they were more satisfied with their labor and delivery experience, as evaluated by Birth Satisfaction Scale questionnaires quality control (37.9±4.7 vs 31.1±5.2; P=.0324), patient attributes (35.0±5.1 vs 30.3±6.3; P=.0453), and stress experienced (58.1±8.5 vs 50.1±8.3; P=.0398). No side effects or adverse outcomes were reported in either group. CONCLUSION: A scheduled analgesic protocol for postpartum pain management following vaginal delivery revealed similar pain scores compared with an on-demand protocol, although it was associated with higher breastfeeding rates and higher maternal satisfaction.

Preoperative anxiety and postoperative pain associated with cataract surgery under local anesthesia.

INTRODUCTION: Although cataract surgery is a routine outpatient surgery, anxiety and pain remain two significant concerns seen in patients. AIM: To describe preoperative anxiety and postoperative pain related to cataract surgery under local anesthesia and identify the factors determining their occurrence. METHODS: This is a cross-sectional, descriptive and analytical, study which included patients who underwent cataract surgery for the first eye in the ophthalmology department of Habib Bourguiba University Hospital in Sfax-Tunisia. Preoperative anxiety was assessed using the Amsterdam Preoperative Anxiety and Information Scale. Postoperative pain was measured using the visual analog scale. RESULTS: A total of 203 patients were included with a sex ratio (M/F) of 0.79. The average age was 67.73±9.4 years. The mean overall preoperative anxiety score was 10.8±5.2. The average score for the need for information among patients was 3.45±1.5. The most anxiety-provoking factor was the possibility of surgery failure and loss of the operated eye. The determining factors for anxiety were young age and female gender. The average postoperative pain score in our patients was 3.51±1.8. A weakly positive correlation was noted between pain and duration of the procedure. CONCLUSION: Managing anxiety and pain related to cataract surgery through preoperative education and adequate management is necessary to improve patient comfort and well-being.

Transversus Thoracic Muscle Plane Block For Postoperative Pain in Pediatric Cardiac Surgery: A Systematic Review And Meta-Analysis of Randomized And Observational Studies.

OBJECTIVES: Pediatric patients undergoing cardiac surgery usually experience significant surgical pain. Additionally, the effect of poor surgical analgesia creates a pain continuum that extends to the postoperative period. Transversus thoracic muscle plane block (TTMPB) is a novel plane block technique that can provide analgesia to the anterior chest wall. The analgesic role of TTMPB in pediatric cardiac surgery is still uncertain. A meta-analysis was conducted to determine the analgesic efficacy of this procedure. DESIGN AND SETTING: Systematic review and meta-analysis. PubMed, Embase, Web of Science, CENTRAL, WanFang Data, and the China National Knowledge Infrastructure were searched to November 2023, and the Grading of Recommendations Assessment, Development, and Evaluation approach was followed to evaluate the certainty of evidence. PARTICIPANTS: Eligible studies enrolled pediatric patients from 2 months to 12 years old scheduled to undergo cardiac surgery, and randomized them to receive a TTMPB or no block/sham block. MEASUREMENTS AND MAIN RESULTS: Six studies that enrolled 601 pediatric patients were included. Low-certainty evidence from randomized trials showed that, compared with no block or sham block, TTMPB in pediatric patients undergoing cardiac surgery may reduce postoperative modified objective pain score at 12 hours (weighted mean difference [WMD] -2.20, 95% CI -2.73 to -1.68) and 24 hours (WMD -1.76, 95% CI -2.09 to -1.42), intraoperative opioid consumption (WMD -3.83, 95% CI -5.90 to -1.76 µg/kg), postoperative opioid consumption (WMD -2.51, 95% CI -2.84 to -2.18 µg/kg), length of intensive care unit (ICU) stay (WMD -5.56, 95% CI -8.30 to -2.83 hours), and extubation time (WMD -2.13, 95% CI -4.21 to -0.05 hours). Retrospective studies provided very low certainty that the results were consistent with the randomized trials. CONCLUSION: Very low- to low-certainty evidence showed that TTMPB in pediatric patients undergoing cardiac surgery may reduce postoperative pain, opioid consumption, ICU length of stay, and extubation time.

Efficacy of bilateral catheter superficial parasternal intercostal plane blocks using programmed intermittent bolus for opioid-sparing postoperative analgesia in cardiac surgery with sternotomy: A randomized, double-blind, placebo-controlled trial.

STUDY OBJECTIVE: This study investigated whether catheter superficial parasternal intercostal plane (SPIP) blocks, using a programmed intermittent bolus (PIB) with ropivacaine, could reduce opioid consumption while delivering enhanced analgesia for a period exceeding 48 h following cardiac surgery involving sternotomy. DESIGN: A double-blind, prospective, randomized, placebo-controlled trial. SETTING: University-affiliated tertiary care hospital. PATIENTS: 60 patients aged 18 or older, scheduled for cardiac surgery via sternotomy. INTERVENTIONS: The patients were randomly assigned in a 1:1 ratio to either the ropivacaine or saline group. After surgery, patients received bilateral SPIP blocks for 48 h with 0.4% ropivacaine (20 mL per side) for induction, followed by bilateral SPIP catheters using PIB with 0.2% ropivacaine (8 mL/side, interspersed with a 2-h interval) or 0.9% normal saline following the same administration schedule. All patients were administered patient-controlled analgesia with hydromorphone. MEASUREMENTS: The primary outcome was the cumulative morphine equivalent consumption during the initial 48 h after the surgery. Secondary outcomes included postoperative pain assessment using the Numeric Rating Scale (NRS) at rest and during coughing at designated intervals for three days post-extubation. Furthermore, recovery indicators and ropivacaine plasma levels were diligently documented. MAIN RESULTS: Cumulative morphine consumption within 48 h in ropivacaine group decreased significantly compared to saline group (25.34 ± 31.1 mg vs 76.28 ± 77.2 mg, respectively; 95% CI, -81.9 to -20.0, P = 0.002). The ropivacaine group also reported lower NRS scores at all recorded time points (P < 0.05) and a lower incidence of nausea and vomiting than the saline group (3/29 vs 12/29, respectively; P = 0.007). Additionally, the ropivacaine group showed significant improvements in ambulation (P = 0.018), respiratory exercises (P = 0.006), and self-reported analgesia satisfaction compared to the saline group (P = 0.016). CONCLUSIONS: Bilateral catheter SPIP blocks using PIB with ropivacaine reduced opioid consumption over 48 h, concurrently delivering superior postoperative analgesia in adult cardiac surgery with sternotomy.

The Effect of Virtual Reality Practice and Music on Patients' Pain, Comfort, and Vital Signs After Laparoscopic Abdominal Surgery.

AIM: This research was conducted to identify the effect of virtual reality and music on patients' pain, comfort, and vital signs after laparoscopic abdominal surgery. METHODS: This study was designed as a prospective randomized controlled single-blind clinical trial. The research population consisted of adult patients who underwent laparoscopic abdominal surgery in surgery clinics. The research sample comprised 225 patients who had laparoscopic abdominal surgery. Experimental groups watched virtual reality videos and listened to music, whereas no intervention was administered to the control group. The research data were evaluated with descriptive statistics, the χ 2 test, the Friedman test, the one-way analysis of variance, the Kruskal-Wallis test, and Tukey's and Dunn's post hoc tests. FINDINGS: In the post-test phase after the 2 interventions, the virtual reality and music groups had lower pain and comfort levels than the control group, and this intergroup difference was statistically significant ( P <0.05). Results for vital signs in successively repeated post-test measurements after interventions were in general different, and these differences were statistically significant. Patients in the virtual reality group generally had higher pulse rate, diastolic blood pressure, respiratory rate, and body temperature values in successively repeated post-test measurements than patients in other groups ( P <0.05). Patients in the control group generally had higher systolic blood pressure and saturation values in successively repeated post-test measurements than patients in other groups ( P <0.05). CONCLUSION: It was discerned that music and the virtual reality practice reduced patients' pain and comfort levels and had positive effects on their vital signs after laparoscopic abdominal surgery.

Current perioperative nociception monitoring and potential directions.

Perioperative nociception-antinociception balance is essential for the prevention of adverse postoperative events. Estimating the nociception level helps optimize intraoperative management. In the past two decades, various nociception monitoring devices have been developed for the identification of intraoperative nociception. However, each type of nociception monitoring device has advantages and disadvantages, limiting their clinical application in particular patients and settings. Therefore, this review aimed to summarize the information on nociceptor monitoring in current clinical settings, explore each technique's particularities, and possible future directions to provide a reference for clinicians and researchers.

Fascia iliaca compartment block for postoperative pain after total hip arthroplasty: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Fascia iliaca compartment block (FICB) is one of the regional nerve blocks used to reduce pain after total hip arthroplasty (THA). We aim to assess the efficacy of FICB in reducing post-operative pain and opioid consumption. METHODS: We searched PubMed, Web of Science, Cochrane Library, Embase, and Scopus on February 19, 2023, and we updated our search in august 2023 using relevant search strategy. Studies were extensively screened for eligibility by title and abstract screening, followed by full-text screening. We extracted the data from the included studies, and then pooled the data as mean difference (MD) or odds ratio (OR) with a 95% confidence interval (CI), using Review Manager Software (ver. 3.5). RESULTS: FIBC significantly reduced analgesic consumption at 24 h (MD = -8.75, 95% CI [-9.62, -7.88] P < 0.00001), and at 48 h post-operatively. (MD = -15.51, 95% CI [-26.45, -4.57], P = 0.005), with a significant sensory block of the femoral nerve (P = 0.0004), obturator nerve (P = 0.0009), and lateral femoral cutaneous nerve (P = 0.002). However, FICB was not associated with a significant pain relief at 6, 24, and 48 h postoperatively, except at 12 h where it significantly reduced pain intensity (MD = -0.49, 95% CI [-0.85, -0.12], P = 0.008). FICB was also not effective in reducing post-operative nausea and vomiting (MD = 0.55, 95% CI [0.21, 1.45], P = 0.23), and was associated with high rates of quadriceps muscle weakness (OR = 9.09, % CI [3.70, 22.30], P = < 0.00001). CONCLUSIONS: FICB significantly reduces the total analgesic consumption up to 48 h; however, it is not effective in reducing post-operative pain, nausea and vomiting and it induced postoperative muscle weakness.

Comparative Analysis of Temperature-Responsive Hydrogel (PF 72) for Postoperative Pain After Bimaxillary Surgery: A Retro-spective Study.

Bimaxillary surgery is a painful invasive procedure in plastic surgery. Pain control is typically achieved using intravenous analgesics. We aimed to investigate the efficacy of a novel temperature-responsive hydrogel, PF72, mixed with ropivacaine, as a local pain management solution when applied directly to the surgical site following orthognathic surgery. The study was conducted from October 2022 to July 2023 and included a cohort of 40 candidates for orthognathic surgery, encompassing LeFort I maxillary ostectomy and sagittal split ramus osteotomy. The participants were divided into an Injection group (n = 20), where PF72 was administered at the surgical site before the orthognathic surgery, and a Control group (n = 20), which relied solely on intravenous analgesics. Pain was evaluated at 3, 6, 24, 48, and 72 h after surgery using a numerical rating scale (NRS). The mean NRS scores at 24 h were 6.35 and 4 for the Control and Injection groups, respectively. The mean NRS scores at 72 h were 3.4 and 2.55 for the Control and Injection groups, respectively. Patients who received PF72 experienced less pain than those who received intravenous analgesics. These findings underscore the potential of PF72 as an effective alternative for enhancing pain management in patients undergoing orthognathic surgery.Level of Evidence III Therapeutic study.

Pain management after open colorectal surgery: An update of the systematic review and procedure-specific postoperative pain management (PROSPECT) recommendations.

BACKGROUND: Open colectomy is still performed around the world and associated with significant postoperative pain. OBJECTIVES: Unpublished recommendations based on a systematic review were proposed by the PROcedure SPECific postoperative pain managemenT (PROSPECT) group in 2016. We aimed to update these recommendations by evaluating the available literature and develop recommendations for optimal pain management after open colectomy according to the PROSPECT methodology. DESIGN AND DATA SOURCES: A systematic review using the PROSPECT methodology was undertaken. Randomised controlled trials and systematic reviews published in the English language from 2016 to 2022 assessing postoperative pain after open colectomy using analgesic, anaesthetic or surgical interventions were identified. The primary outcome included postoperative pain scores. RESULTS: The previous 2016 review included data from 93 studies. Out of 842 additional eligible studies identified, 13 new studies were finally retrieved for analysis. Intra-operative and postoperative interventions that improved postoperative pain were paracetamol, epidural analgesia. When epidural is not feasible, intravenous lidocaine or bilateral TAP block or postoperative continuous pre-peritoneal infusion are recommended. Intra-operative and postoperative Cyclo-oxygenase (COX)-2 specific-inhibitors or non-steroidal anti-inflammatory drugs (NSAIDs) are recommended for colonic surgery. CONCLUSIONS: The analgesic regimen for open colectomy should include intra-operative paracetamol and COX-2 specific inhibitors or NSAIDs (restricted to colonic surgery), epidural and continued postoperatively with opioids used as rescue analgesics. If epidural is not feasible, bilateral TAP block or IV lidocaine are recommended. Safety issues should be highlighted: local anaesthetics should not be administered by two different routes at the same time. Because of the risk of toxicity, careful dosing and monitoring are necessary.
