Transcutaneous electrical nerve stimulation for reducing postoperative acute pain after hip fracture surgery: a double-blinded randomized clinical trial.

OBJECTIVE: The aim of this study was to assess the effects of two different applications of transcutaneous electrical nerve stimulation (TENS) on the reduction of postoperative acute pain after hip fracture surgery. PATIENTS AND METHODS: In this study, 120 patients undergoing hip surgery were divided into three groups. The first group received patient-controlled analgesia (PCA) with epidural fentanyl and additional medications. The second group received lumbar plexus and sciatic nerve transcutaneous electrical nerve stimulation (LS-TENS) along with the same medication protocol as the first group. The third group received the same medication protocol as the first group, as well as surgical wound transcutaneous electrical nerve stimulation (SW-TENS). Pain levels were measured using a Visual Analog Scale (VAS) score, and the number of opioid analgesics used by each patient was recorded. VAS score and the total consumption of opioid analgesics were meticulously documented. RESULTS: VAS scores were higher in the control group than in the SW-TENS group at 30 min (1.58±2.49 vs. 0.70±2.15, p<0.05) and in the SW-TENS group than in the LS- TENS group at 24 h postoperatively (2.33±1.29 vs. 1.63±1.05, p<0.05). The 48-h total analgesic consumption level of the control group was higher than that of the LS-TENS group (p<0.05). CONCLUSIONS: The findings of this study indicate that TENS application to the surgical wound, lumbar plexus, and sciatic nerve using anatomical landmarks can significantly reduce postoperative pain, as demonstrated by the higher VAS scores, higher total analgesic consumption and high additional analgesic need in the control group after hip fracture surgery.

[A prospective comparative study on effectiveness of single versus continuous adductor canal block combined with local infiltration anesthesia in unicompartmental knee arthroplasty].

Objective: To compare the early analgesic effects and the impact on knee joint function recovery after unicompartmental knee arthroplasty (UKA) between single adductor canal block (SACB) and continuous adductor canal block (CACB) combined with local infiltration anesthesia (LIA) using a prospective study. Methods: The patients with knee osteoarthritis admitted between April 2022 and December 2023 were enrolled as a subject. Among them, 60 patients met the selection criteria and were enrolled in the study. They were randomly assigned to the SACB group or CACB group in a ratio of 1:1 using a random number table method. There was no significant difference between the two groups ( P>0.05) in terms of age, gender, height, body mass, body mass index, affected side, and preoperative resting visual analogue scale (VAS) score and active VAS score, Oxford knee score (OKS), and American Hospital of Special Surgery (HSS) score. All patients received multimodal analgesia management using LIA combined with SACB or CACB. The operation time, pain related indicators (resting and activity VAS scores, number and timing of breakthrough pain, opioid consumption), joint function related indicators (quadriceps muscle strength, knee range of motion, OKS score, and HSS score), as well as postoperative block complications and adverse events were recorded and compared between the two groups. Results: There was no significant difference in the operation time between the two groups ( P<0.05). All patients in the two groups were followed up with a follow-up time of (9.70±4.93) months in the SACB group and (12.23±5.05) months in the CACB group, and the difference was not significant ( P>0.05). The CACB group had a significant lower resting VAS score at 24 hours after operation compared to the SACB group ( P<0.05). There was no significant difference in resting and active VAS scores between the two groups at other time points ( P>0.05). The CACB group had a significantly lower incidence of breakthrough pain compared to the SACB group [9 cases (30.00%) vs. 17 cases (56.67%); P<0.05). However, there was no significant difference in the timing of breakthrough pain occurrence and opioid consumption between the two groups ( P>0.05). Four cases in the SACB group and 7 cases in the CACB group experienced adverse events, with no significant difference in the incidence of adverse events between the two groups ( P>0.05). The CACB group had significantly better knee joint mobility than the SACB group at 1 and 2 days after operation ( P<0.05). There was no significant difference between the two groups in knee joint mobility on 0 day after operation and quadriceps muscle strength and OKS and HSS scores at different time points ( P>0.05). Conclusion: In UKA, the analgesic effects and knee joint function recovery are similar when compared between LIA combined with SACB and LIA combined with CACB. However, SACB is simpler to perform and can avoid adverse events such as catheter displacement and dislocation. Therefore, SACB may be a better choice.

Effect of Intraoperative infusion Magnesium Sulfate Infusion on Postoperative Quality of Recovery in Patients Undergoing Total Knee Arthroplasty: A Prospective, Double-Blind, Randomized Controlled Trial.

Background: Magnesium sulfate, an intravenous adjuvant, has recently attracted immense attention in multimodal analgesia. Previous studies confirmed the crucial role of magnesium sulfate in postoperative pain and nociceptive hypersensitivity. However, the effect of magnesium sulfate in multimodal analgesia on the quality of recovery (QoR) for elderly patients has not been thoroughly studied. Therefore, the present experiment aimed to investigate the effect of continuous intravenous magnesium sulfate on the quality of postoperative recovery in elderly patients undergoing total knee arthroplasty (TKA). Patients and Methods: In this study, a total of 148 patients scheduled to undergo unilateral total knee arthroplasty were randomized into a magnesium sulfate group (Group M, n=68) and a control group (Group C, n=66) using a double-blind, randomized controlled trial. Before induction of anesthesia, Group M received intravenous magnesium sulfate (40 mg/kg) for 15 min, followed by a continuous infusion (15 mg/kg) until the end of the procedure. In the same manner, Group C received an infusion of the same amount of isotonic saline using the same method as the Group M. Results: Compared with Group C, Group M had significantly better QoR-15 scores on postoperative day 1(POD1) than Group C (P <0.05). Analysis of the dimensions of QoR-15 scores indicated that Group M exhibited notably reduced levels of pain, and higher levels of emotional state and physical comfort than Group C (P <0.05). Furthermore, Group C had significantly higher numerical rating scale (NRS) scores at POD1 than Group M (P <0.05). Conclusion: For elderly patients undergoing knee arthroplasty, magnesium sulfate can be used as an adjuvant in a multimodal analgesic regimen to reduce early postoperative pain and improve the quality of early postoperative recovery.

Ketamine intolerance in patients on enhanced recovery after surgery protocols undergoing colorectal operations.

BACKGROUND: Ketamine is used in enhanced recovery after surgery (ERAS) protocols because of its beneficial antihyperalgesic and antitolerance effects. However, adverse effects such as hallucinations, sedation, and diplopia could limit ketamine's utility. The main objective of this study was to identify rates of ketamine side effects in postoperative patients after colorectal surgery and, secondarily, to compare short-term outcomes between patients receiving ketamine analgesia and controls. METHODS: This was a retrospective observational cohort study. Subjects were adults who underwent ERAS protocol-guided colorectal surgery at a large, integrated health system. Patients were grouped into ketamine-receiving and preketamine cohorts. Patients receiving ketamine were divided into tolerant and intolerant groups. Propensity score-adjusted models tested multivariate associations of ketamine tolerance/intolerance vs control group. RESULTS: A total of 732 patients underwent colorectal surgery within the ERAS program before ketamine's introduction (control). After ketamine's introduction, 467 patients received the medication. Intolerance was seen in 29% of ketamine recipients, and the most common side effect was diplopia. Demographics and surgical variables did not differ between cohorts. Multivariate models revealed no significant differences in hospital stays. Pain scores in the first 24 hours after surgery were slightly higher in patients receiving ketamine. Opiate consumption after surgery was lower for both ketamine tolerant and ketamine intolerant cohorts than for controls. CONCLUSION: Rates of ketamine intolerance are high, which can limit its use and potential effectiveness. Ketamine analgesia significantly reduced opiate consumption without increasing hospital stays after colorectal surgery, regardless of whether it was tolerated.

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.

The Similarities and Differences of Nurse-Postoperative Patient Dyads' Attitudes, Social Norms, and Behaviors Regarding Pain and Pain Management.

PURPOSE: Pain is an expected symptom in surgical patients, despite advances in pharmacology, surgical procedures, and perioperative care. The aim of this study was to examine the similarities and differences between nurse-postoperative patient dyads of the same or differing cultures/ethnicities with regard to perceptions, social norms, and behaviors related to pain and pain management. DESIGN: This was a descriptive qualitative study. METHODS: The sample consisted of six nurses (2 Hispanic, 2 Black, 2 Caucasian) and 12 patients of the same and different culture/ethnicity than their nurse) on a postoperative unit within 48 hours of surgery. A structured interview guide was developed to explore the attitudes, social norms, and behaviors of nurses related to pain and pain management, and a separate interview guide was developed for postoperative patients. All transcripts were analyzed and coded using Carini's principles. FINDINGS: Nurses used the pain scale to quantify pain intensity but did not conduct a comprehensive pain assessment. Nurses were concerned about opioid side effects and addiction and hesitated to provide opioids after the first postoperative day. Patients expected complete and immediate pain relief, with no worry about short-term opioid use. Patients did not believe that culture played a role in their care, but nurses were more comfortable caring for patients from the same cultural background. The use of complementary and nonpharmacologic pain management techniques was not well known by nurses and patients, but should be used in conjunction with medications. CONCLUSIONS: Nursing education stresses cultural competence, but nurses emphasize "treating all patients the same," which creates a cognitive dissonance, with implications for education. Nurses should conduct a comprehensive pain assessment to inform pain management and nonpharmacologic and complementary therapies should be available on the postoperative unit.

Effect of transcutaneous electrical acupoint stimulation on the quality of postoperative recovery: a meta-analysis.

BACKGROUND: The purpose of the present study was to systematically delve into the efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) on the quality of recovery after general anesthesia. METHODS: Randomized controlled trials related to TEAS improving postoperative recovery quality were searched in Cochrane Library, Web of Science, Embase, PubMed, CNKI, VIP, Wanfang and Chinese biomedical database from the inception of each database to June 2023. After literature screening and data extraction, Stata15 software was employed for meta-analysis, and the quality of the included literature was evaluated utilizing ROB2. RESULTS: The study included 10 articles involving 2,383 patients in total. The meta-analysis results unveiled that TEAS could improve 24-hour and 48-hour postoperative QoR-40 scores as well as 24-hour postoperative QoR-40 dimension scores [WMD = 8.52, 95%CI (5.12, 11.91), P < 0.001; WMD = 1.99, 95%CI (0.91, 3.07), P < 0.001], emotional state [WMD = 1.38, 95%CI (0.66, 2.09), P < 0.001], physical comfort [WMD = 2.99, 95%CI (1.59, 4.39), P < 0.001], psychological support [WMD = 0.63, 95%CI (0.36, 0.90), P < 0.001], and physical independence [WMD = 0.76, 95%CI (0.22, 1.30), P = 0.006]; pain [WMD = 1.81, 95%CI (0.87, 2.75), P < 0.001]; decrease 24-hour postoperative VAS pain scores [WMD = -0.84, 95%CI (-1.45, -0.23), P = 0.007] and the incidence of postoperative nausea and vomiting [RR = 0.88, 95%CI (0.81, 0.97), P = 0.006; RR = 0.62, 95%CI (0.52, 0.73), P < 0.001]. CONCLUSION: TEAS can improve postoperative QoR-40 scores and the quality of recovery, relieve pain, and decrease the incidence of nausea and vomiting after surgery in patients who underwent general anesthesia.

Complementary and alternative therapies for managing postoperative pain after lower third molar surgery: a systematic review and network meta-analysis.

OBJECTIVE: The objective of this study was to evaluate the impact of complementary and alternative treatments on postoperative pain following lower third molar surgeries. METHODS: A comprehensive search of Electronic databases (Embase, MEDLINE via PubMed, and Cochrane Library) and grey literature was conducted up until May 2022. Randomized clinical trials investigating the effect of acupuncture, ozone therapy, laser (LLLT), drainage tube, kinesio-taping, ice therapy, and compressions on pain after LTM surgeries were included. The estimated mean differences (MD) for alternative therapies were pooled using the frequentist approach to random-model network meta-analysis NMA. RESULTS: Eighty-two papers were included in the qualitative analysis; 33 of them were included in the quantitative analyzes. NMA revealed that drainage tube and kinesio-taping were superior in controlling pain 24-hours postoperatively than no-treatment. At 48-hours follow-up, kinesio-taping and LLLT more effective than placebo and drainage tube; and kinesio-taping and LLLT were superior to no treatment. At 72 h postoperatively, ozone therapy was superior to placebo; and drainage tube, kinesio-taping, and LLLT were better than no treatment. At 7-days follow-up, ozone and LLLT were superior to placebo; and LLLT and kinesio-taping were superior to no treatment. The SUCRA-ranking placed drainage tube as top-ranking intervention at 48-hours (98.2%) and 72-hours (96%) follow-ups, and ozone (83.5%) at 7-days follow-up. CONCLUSION: The study findings suggest that these alternative and complementary therapies may be useful in reducing postoperative pain after LTM surgeries, and may offer advantages when combined to traditional pain management methods. CLINICAL RELEVANCE: Non-pharmacological therapies are gaining popularity among healthcare professionals and patients. This study found that some of these therapies, specifically kinesio-taping and drainage tube were effective in controlling postoperative pain after third molar surgeries. These findings have important implications for clinical practice, as they highlight the potential benefits of incorporating these therapies into postoperative pain management plans.

A systematic review and meta-analysis on the effects of phototherapy on postoperative pain in conventional endodontic reintervention.

OBJECTIVES: This systematic review and meta-analysis (SRM) aimed to evaluate the efficacy of laser phototherapy (LPT) on the reduction in postoperative pain (PP) of endodontic origin after conventional/non-surgical reintervention of root canals. METHODS: This SRM was registered with PROSPERO (CRD42021243500) and followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Meta-analysis was conducted using R software with the "META" package, the mean difference (MD) measure of effect was calculated, and the fixed effect model was applied with a 95% confidence interval (CI). The Cochrane collaboration scale was used to assess the risk of bias and the GRADE tool to assess the quality of evidence. RESULTS: Initially, 1028 articles were found, and five articles were included. Most studies were classified as "low" risk of bias. Of the five clinical studies, four showed a significant decrease in PP after endodontic reintervention in the LPT groups compared to the control group, especially in the first four days after the intervention. In symptomatic teeth with multiple roots, LPT led to less PP at 24 h (MD -0.52 [-1.03; -0.02] p = .04). However, no significant difference between the groups was found at 48 and 72 h (p > .05). The certainty of the evidence was classified as low. CONCLUSION: Despite the limitations of this SRM, LPT was shown to be a promising alternative for reducing and controlling PP in conventional endodontic reintervention. CLINICAL SIGNIFICANCE: The use of LPT in endodontic reintervention may be a safe and promising alternative to clinically efficacious agent for use in the management of PP in this procedure.

Application of Perioperative Pain Management in the Perioperative Nursing of Labia Minora Plasty and its Effect on the Rehabilitation of Patients.

Objective: The objective of this study is to investigate effective pain management strategies for women undergoing labiaplasty surgery. By focusing on pain relief, patient rehabilitation, and satisfaction improvement, we aim to enhance the overall patient experience and outcomes of this common gynecological plastic surgery. Methods: A total of 126 individuals diagnosed with labia minora hypertrophy and who underwent plastic surgery on their labia minora within the period of July 2020 to July 2023 were chosen as the participants for this study. They were divided into an observation group and a comparison group, each consisting of 63 cases, based on the different nursing methods. The comparison group was treated with routine perioperative nursing after labia minora surgery, and the observation group was treated with perioperative pain nursing management based on the comparison group. Postoperative pain score, comfort score, incision healing time, first urination time, night Pittsburgh Sleep Quality Index (PSQI) score, complications, and satisfaction were compared between the two groups. All data were established in an Excel database, and statistical analysis was performed using SPSS26.0. Statistical methods used include descriptive analysis, t tests, and Chi-square tests. Results: The mean incision healing time of the observation group was 3.90±0.61 days, and that of the control group was 3.62±0.64 days. The mean incision healing time of the observation group was significantly different from that of the control group (P < .05). VRS scores and PSQI scores were significantly lower in both groups 1 week aftercare compared with 1 day before care, indicating improvements in pain and sleep quality. The improvement degree of VRS score and PSQI score in the observation group was significantly different (P < .05). The number of incision infections, hematoma, flap necrosis, skin scar, delayed healing, and total complication rate were 3 in the observation group and 11 in the comparison group, indicating that the complication rate in the observation group was significantly lower than that in the comparison group. The comparison difference was statistically significant (P < .05). Through the Chi-square test, the nursing satisfaction and perineal aesthetic effect satisfaction of the observation group were significantly higher than those of the comparison group, and the difference was statistically significant (P < .05). Conclusions: The implementation of perioperative pain nursing management has been shown to effectively alleviate pain in patients diagnosed with labia minora hypertrophy. This approach not only enhances treatment comfort but also significantly reduces the occurrence of postoperative complications. Additionally, it accelerates the healing process of incisions, improves the quality of incision healing, and enhances patient satisfaction with both the aesthetic outcome of the perineal area and the quality of nursing care provided.

Tailored Yoga Intervention for Postlumbar Spine Surgical Pain Management: A Feasibility Study.

Introduction: Severe pain, anxiety, and high opioid use are common following lumbar spine surgery (LSS). Yoga helps to reduce pain and anxiety, but it has not been considered for postsurgical care. The authors developed and tested the feasibility of a tailored yoga program designed for individuals undergoing LSS and explored clinical feasibility of yoga intervention on measures of pain, function, psychological status, and opioid use. Methods: Individuals scheduled for LSS were randomized into yoga versus control groups presurgery. Participants in the yoga group received tailored yoga sessions plus usual care, whereas participants in the control group received usual care only during the hospital stay post-LSS. In-person daily yoga sessions were individually presented and performed in the participant's hospital room. Feasibility was assessed by recruitment and retention rates, rate of yoga session completion, tolerance to yoga intervention, and ability to carry out planned assessment. Exploratory clinical outcomes included pain, psychological measures, Timed-Up-and-Go test, gait distance, and opioid use, during the hospital stay post-LSS. Results: Forty-one participants were enrolled, of which 30 completed. There were no dropouts. Planned assessments were completed within 45 min, suggesting no excessive burden on participants. Baseline variables were similar across both groups. The majority of participants participated in yoga intervention on the day of surgery or one day after surgery with acceptance rate of 100%. Participants showed good tolerance to yoga intervention on 0-4 tolerance scale and by their reports of exploratory clinical outcomes. Conclusion: This study indicates feasibility for a modified yoga program for postoperative care following LSS due to participant tolerance and retention. The results provide preliminary framework for future confirmatory studies that can assess the potential benefits of yoga in reducing pain, catastrophizing behavior, and opioid use and improving function. A modified yoga program focusing on diaphragmatic breathing, relaxation, and core isometric contraction exercises can be an important adjunct intervention for patients undergoing LSS.

An Evaluation of the Effects of Pineapple-Extract and Bromelain-Based Treatment after Mandibular Third Molar Surgery: A Randomized Three-Arm Clinical Study.

A three-arm, randomized, placebo-controlled clinical study was conducted to assess the impact of lyophilized pineapple extract with titrated bromelain (Brome-Inf®) and purified bromelain on pain, swelling, trismus, and quality of life (QoL) following the surgical extraction of the mandibular third molars. Furthermore, this study examined the need for Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) by comparing their effects with a placebo group. This study enrolled 42 individuals requiring the extraction of a single mandibular third molar under local anesthesia. The patients were randomly assigned to receive Brome-Inf®, purified bromelain, or a placebo orally, initiating treatment on the day of surgery and continuing for the next 7 days. The primary outcome measured was the requirement for NSAIDs in the three groups. Pain, swelling, and trismus were secondary outcome variables, evaluated postoperatively at 1, 3, and 7 days. This study also assessed the comparative efficacy of freeze-dried pineapple extract and single-component bromelain. Ultimately, the placebo group showed a statistically higher need for ibuprofen (from days 1 to 7) at the study's conclusion (p < 0.0001). In addition, reductions in pain and swelling were significantly higher in both the bromelain and pineapple groups (p < 0.0001 for almost all patients, at all intervals) than in the placebo group. The active groups also demonstrated a significant difference in QoL compared to the placebo group (p < 0.001). A non-significant reduction in trismus occurred in the treatment groups compared to the placebo group. Therefore, the administration of pineapple extract titrated in bromelain showed significant analgesic and anti-edema effects in addition to improving QoL in the postoperative period for patients who had undergone mandibular third molar surgery. Moreover, both bromelain and Brome-Inf® supplementation reduced the need for ibuprofen to comparable extents, proving that they are good alternatives to NSAIDs in making the postoperative course more comfortable for these patients. A further investigation with larger samples is necessary to assess the pain-relieving and anti-inflammatory impacts of the entire pineapple phytocomplex in surgical procedures aside from mandibular third molar surgery.

Effect of Humanistic Pain Management in Postpartum Women after Cesarean Delivery Based on Active Pain Assessment and Visual Analog Scale.

Objective: To explore the effect of humanistic pain management based on active pain assessment and the visual analog scale in postpartum women after cesarean delivery. Methods: We selected 100 postpartum women who underwent cesarean delivery in Xuzhou Maternity and Child Health Care Hospital from April to December 2021 and divided the postpartum women into a management group and a conventional group, with 50 cases in each group. The conventional group was given routine pain management, while the management group was given humanistic pain management based on active pain assessment and visual analog scale score. The quality of pain management, sleep quality, unhealthy emotion, maternal comfort, breastfeeding rates, and patient compliance in the 2 groups were compared. Results: The most severe degree of pain, the least degree of pain, the frequency of moderate and severe pain, and the influence of pain on sleep were lower in the management group than in the conventional group. The Pittsburgh Sleep Quality Index score was lower and the Self-Rating Anxiety Scale and the Self-Rating Depression Scale scores were higher in the management group than in the conventional group. In addition, the comfort scores for the second day and the third day after delivery were higher in the management group than in the conventional group. The breastfeeding rate and patient compliance were higher in the management group than in the conventional group. Conclusion: Humanistic pain management based on active pain assessment and the visual analog scale can improve the quality of maternal pain management, the quality of sleep, and maternal comfort, ameliorate maternal adverse emotions, and promote breastfeeding and patient compliance.

The value of local dexmedetomidine as an adjuvant to ultrasound-guided wide awake local anesthesia no tourniquet (WALANT) in flexor tendon repair surgeries: a randomized controlled trial.

BACKGROUND: The Wide-Awake Local Anesthesia No Tourniquet (WALANT) technique allows intraoperative motor assessment of tendon repair integrity of the hand compared with general anesthesia or brachial plexus block. No studies have tested the effect of adding dexmedetomidine to lidocaine on the analgesic properties of the WALANT technique, which is the aim of our study. METHODS: A total of 128 patients aged more than 18 years were scheduled for surgical flexor tendon injury repair using WALANT technique. Patients were divided into two equal groups. Ultrasound-guided subcutaneous injection of lidocaine 1% with dexmedetomidine (1 µg/kg), Group D, or without dexmedetomidine, Group C, was performed at four points: proximal to the wrist joint, the distal forearm, palm region, and proximal phalanges. The primary outcome was total morphine consumption throughout the first postoperative day. Secondary outcomes included number of patients requiring rescue analgesia, time to first analgesic request, and pain score. RESULTS: Total morphine consumption was significantly (P < 0.001) lower in group D (2.66 ± 0.998) than in group C (3.66 ± 1.144) mg. Number of patients requiring rescue analgesia was significantly (P < 0.001) lower in group D (54.7% (35)) than group C (100.0% (64)). The time for first request for analgesia was significantly (P < 0.001) longer in group D (11.31 ± 6.944) than in group C (5.91 ± 4.839) h. Pain score was significantly higher in group C than D at three (P < 0.001), and six (P = 0.001) hours (P = 0.001) postoperatively. CONCLUSION: Dexmedetomidine significantly improves the analgesic quality of WALANT when added to lidocaine with less opioid consumption.

Shoulder pain management strategies and early functional outcome after arthroscopic rotator cuff tear repair. A randomized controlled study.

BACKGROUND: The management of acute postoperative pain after rotator cuff surgery can be challenging. To our knowledge, there are no data available in the literature correlating satisfactory pain control with improvement in terms of function. The purposes of the present study were to evaluate: 1) pain pattern after arthroscopic rotator cuff repair in patients operated with two different techniques (transosseous vs transosseous equivalent); 2) safety/efficacy of three different pharmacological pain control strategies; 3) possible relationship between a correct shoulder pain management protocol in the early post-operative period and patients' functional improvement. METHODS: 114 patients underwent rotator cuff tear repair, either with a Transosseus or a Transosseus equivalent technique. 62 (54%) were male and 52 (46%) were female. The average age was 59 ± 9 years. They were randomly assigned into three different pain management protocols: Paracetamol as needed (max 3 tablets/day) for 1 week (Protocol A), Paracetamol + Codein 1 tablet three times per day for 7 days (Protocol B), or Paracetamol + Ibuprofen 1 tablet two times per day for 7 days (Protocol C). Immediate passive mobilization of the operated shoulder was allowed. VAS and Passive Flexion values were recorded at 7 (T1), 15 (T2) and 30 (T3) days post-surgery. DASH values were recorded at 90 days post-surgery. All patients were asked to register any kind of signs/symptoms that may appear during drug assumption according to each pain management protocols. RESULTS: All the pain management protocols administered were well tolerated by all the study population, and no adverse signs/symptoms were highlighted during drug assumption. Pain pattern: in both surgical techniques, patients within Protocol A were associated with worst results in terms of mean VAS at each time point examined when compared to Protocol B and C (p < 0,05). In patients within Protocol A, no statistically significant differences were found at each point time examined comparing the two surgical techniques, with the exception of T2, where the TO was associated with an higher VAS value than TOE (p < 0.05). No differences were highlighted in Protocol B and C when comparing the values between two surgical techniques. ROM: in both surgical techniques, patients within Protocol A were associated with worst results in terms of mean PROM at each time point examined when compared to Protocol B and C (p < 0,05). In the TO group, patients within Protocol B had better PROM values at T1 (p < 0,05) and T2 (p < 0,05) compared to Protocol C, but no differences were highlighted at T3. In the TOE group, no statistically significant differences were found between patients within Protocol B and C at each time point examined. DASH: In the TO group, no statistically significant differences were found regarding the DASH values comparing Protocol B vs Protocol C, but they were highlighted comparing the values between Protocol A and Protocol B (p < 0,05), and between Protocol A and Protocol C (p < 0,05). Similar results were recorded in the TOE group. CONCLUSION: Post-operative pain is influenced by the surgical technique used being transosseous more painful in the first 15 days after surgery. Oral anti-inflammatory drugs are a feasible strategy to appropriately control post-operative pain. An association between Paracetamol and either Codein or Ibuprofen can lead to better outcomes in terms of VAS reduction and early recovery of passive ROM.

Clinical and thermographic evaluation after lower third molar extractions and the application of different photobiomodulation protocols: double-blind randomised clinical trial.

OBJECTIVES: to compare the parameters of pain, oedema, temperature, and soft tissue closure in dental sockets that received two different photobiomodulation (PBM) protocols following extractions. MATERIALS AND METHODS: Thirty-one participants had their teeth 38 and 48 extracted. Subsequently, one of the dental sockets received PBM at a wavelength (WL) of 808 nanometers (808 group- nm) and the other dental socket received the PBM at WLs of 808 nm and 660 nm, simultaneously (808 + 660 group). The PBM was applied immediately after the surgical procedure and on the 3rd and 7th days. RESULTS: The mean of Visual Analogue Scale (VAS) values for pain were 1.45 for the 3rd day and 0.52 for the 7th day in the 808 + 660 and 808 group, respectively. The mean the pogonion-tragus measurement, used to assess facial oedema on the 3rd day, was 15.38 cm (range 13.5-17.5) in the 808 + 660 group and 15.48 cm (range 14.0-17.5) in the 808 group. The mean facial temperatures in the 808 + 660 group were 34.9 degrees Celsius (ºC) (range 33.5-36.4) on the 3rd day and 35 ºC (range 33.4-36.4) on the 7th day. In the 808 group, the mean temperatures were 34.9 ºC (range 33.9-36.2) on the 3rd day and 34.9 ºC (33.7-36.2) on the 7th day. Regarding the dimensions of the dental socket, the mean were similar for both groups. Significant differences between the groups were only observed in the pain parameter and only on the 7th day, being greater for the 808 + 660 group (p = 0.031). CONCLUSIONS: The association of the 660 nm with 808 nm, and the increase in energy did not showed more benefits in pain reduction oedema, or acceleration of the closure of the soft tissues of the dental sockets of lower third molars, in the protocols used here. CLINICAL RELEVANCE: There is no need to combine lasers at wavelengths of 660 and 808 nm to reduce oedema, pain and repair of soft tissues after extraction of lower third molars. CLINICAL TRIAL REGISTRATION: This trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with the following code: RBR-66pyrh8, on 29th December, 2022.

Effect of Zusanli Acupoint Injection with Anisodamine on Postoperative Recovery Quality of Patients Undergoing Bariatric Surgery.

PURPOSE: To evaluate the influence of anisodamine injection at the Zusanli (ST36) on early postoperative recovery quality in patients who have undergone laparoscopic sleeve gastrectomy. MATERIALS AND METHODS: 141 patients undergoing laparoscopic sleeve gastrectomy were randomly divided into the control group (group C), the normal saline group (group S) and the anisodamine group (group A). Acupuncture point injections were administered after induction of general anesthesia. The quality of recovery-40 questionnaire (QoR-40) scores were documented preoperatively (D0) and on the 1st (D1), 3rd (D3) and 7th (D7) days postoperatively. Additional metrics included: the numerical rating scale (NRS) for pain, postoperative nausea and vomiting (PONV), assessment and analgesic consumption 24-h post-extubation and the initial postoperative times for ambulation and anal exhaust. Substance P (SP), ß-endorphin (ß-EP), motilin (MTL) and gastrin (GAS) were quantified at 24-h post-surgery. RESULTS: Compared with group C, group A demonstrated an elevation in QoR-40 scores and physical comfort dimensions during D1-3, and an increased pain scores during D1-7; group S exhibited an augmentation in QoR-40 scores and pain scores on D1 (p < 0.05). Compared with group S, group A improved QoR-40 scores on D1 and pain scores during D1-3 (p < 0.05). SP, ß-EP, MTL and GAS presented significant variances among the groups 24-h post-surgery (p < 0.05). There were significant differences between the groups in NRS pain scores and PONV scores at 24-h postoperatively, dosage of dizocin on the first postoperative day, and time to first anal defecation (p < 0.05). CONCLUSION: The administration of anisodamine via ST36 acupoint injections has been demonstrated to facilitate the recuperation of gastrointestinal functionality, to alleviate postoperative pain and nausea, and substantially to enhance the quality of early postoperative recovery.

Nonpharmacologic Therapies for Postoperative Pain in Cardiac Surgery: A Systematic Review.

OBJECTIVES: To search for studies that address the efficacy of nonpharmacologic methods for pain relief in adults undergoing cardiac surgeries. DESIGN: A systematic review registered in the International Prospective Register of Systematic Reviews (PROSPERO) under number CRD42020168681. DATA SOURCE: PubMed, LILACS, CINAHL, the Web of Science, Scopus, and the Cochrane Central Register of Controlled Trials. REVIEW/ANALYSIS METHODS: The review used a PRISMA guideline that selected primary randomized controlled trials on the efficacy of nonpharmacologic pain relief therapies in patients undergoing cardiac surgery, with no time or language restrictions. The Joanna Briggs Institute Critical Appraisal Checklist for Randomized Clinical Trials was used to assess methodological rigor. RESULTS: After screening, 23 of the 140 studies found in the databases were selected. The studies examined the efficacy of 13 different nonpharmacologic therapies, as well as a combination of therapies, with massage therapy being the most commonly examined, followed by musical intervention and hypnosis. CONCLUSIONS: Some interventions, when combined with pharmacologic therapy, were effective in relieving postoperative pain after cardiac surgeries, according to the studies analyzed. However, most studies had significant methodological flaws, and further studies with high methodological quality are needed.

Analgesic efficacy of local infiltration anaesthesia versus femoral nerve block in alleviating postoperative wound pain following total knee arthroplasty: A systematic review and meta-analysis.

Total knee arthroplasty (TKA) often involves significant postoperative pain, necessitating effective analgesia. This meta-analysis compares the analgesic efficacy of local infiltration anaesthesia (LIA) and femoral nerve block (FNB) in managing postoperative wound pain following TKA. Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this meta-analysis was structured around the PICO framework, assessing studies that directly compared LIA and FNB in TKA patients. A comprehensive search across PubMed, Embase, Web of Science and the Cochrane Library was conducted without time restrictions. Studies were included based on specific criteria such as participant demographics, study design and outcomes like pain scores and opioid consumption. Quality assessment utilized the Cochrane Collaboration's risk of bias tool. The statistical approach was determined based on heterogeneity, with the choice of fixed- or random-effects models guided by the I2 statistic. Sensitivity analysis and evaluation of publication bias using funnel plots and Egger's linear regression test were also conducted. From an initial pool of 1275 articles, eight studies met the inclusion criteria. These studies conducted in various countries from 2007 to 2016. The meta-analysis showed no significant difference in resting and movement-related Visual Analogue Scale scores post-TKA between the LIA and FNB groups. However, LIA was associated with significantly lower opioid consumption. The quality assessment revealed a low risk of bias in most studies, and the sensitivity analysis confirmed the stability of these findings. There was no significant publication bias detected. Both LIA and FNB are effective in controlling postoperative pain in TKA patients, but LIA offers the advantage of lower opioid consumption. Its simplicity, cost-effectiveness and opioid-sparing nature make LIA the recommended choice for postoperative analgesia in knee replacement surgeries.
