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.

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.

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.

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.

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.

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.

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.

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.

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.

Pain experience in patients undergoing topical anesthesia alone versus topical plus intracameral anesthesia during cataract surgery.

PURPOSE: To evaluate and compare the pain experience and discomfort during cataract surgery and over the 24 hours after surgery in patients undergoing either topical anesthesia alone or topical anesthesia plus intracameral anesthesia, provided by using a standard topical anesthesia regimen and a 0.2-mL dose of Mydrane®. METHODS: Prospective study involving 100 patients who underwent cataract surgery receiving either topical anesthesia alone (group 1, n = 50) or topical anesthesia plus intracameral anesthesia (group 2, n = 50) between January 2021 and March 2022. The pain experienced by patients during and after surgery was assessed using a pain scale and a questionnaire. One hour after surgery, patients were asked to rate the intensity of discomfort they experienced throughout the procedure by pointing to a 0-100 Visual Analogue Scale (VAS). RESULTS: According to VAS measurements, patients who underwent surgery under topical anesthesia reported more significant pain than those who underwent surgery under topical anesthesia plus intracameral anesthesia during and over the 24 hours after surgery. (p = 0.02 and p = 0.01, respectively). Patients undergoing topical anesthesia had 2.34-fold greater odds of having pain during surgery [95% Confidence Interval (CI): 1.58-5.25, p = 0.03]. CONCLUSIONS: Topical anesthesia plus intracameral anesthesia lower intraoperative and postoperative pain levels, improving patient cooperation and representing a useful analgesic delivery method in cataract surgery.

Dexmedetomidine supplementation for surgical field enhancement in endonasal surgery: a systematic review and meta-analysis.

BACKGROUND: Dexmedetomidine has been shown to effectively control intraoperative bleeding and improve surgical field visualization. However, its value in endonasal surgeries remains a matter of debate. METHODOLOGY: We searched PubMed, Embase, and Cochrane Central Register of Controlled Trials for studies comparing dexmedetomidine with placebo in endonasal surgeries. Outcomes included bleeding, operative time (OT), surgeon’s satisfaction, postoperative pain (POP), and nausea/vomiting (PONV). For statistical analysis, we used RevMan 5.4.1, and assessed heterogeneity with I2 statistics. RESULTS: We included a total of 1386 patients from 22 studies. In the placebo group, there was higher bleeding volume, whereas the dexmedetomidine group showed lower scores on the Fromme-Boezaart scale. Additionally, the surgeon satisfaction risk ratio (RR) increased, and OT was reduced in the dexmedetomidine group. The dexmedetomidine group had lower incidences of POP and PONV. CONCLUSIONS: In endonasal surgeries, dexmedetomidine was associated with improvements in surgical field visualization as evidenced by reduced intraoperative bleeding and postoperative morbidities.

Effectiveness of acupuncture for postoperative gastrointestinal recovery in patients undergoing thoracoscopic surgery: a prospective randomized controlled study.

BACKGROUND: Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications among patients who have undergone thoracic surgery. Acupuncture has long been used in traditional Chinese medicine to treat gastrointestinal diseases and has shown benefit as an alternative therapy for the management of digestive ailments. This study aimed to explore the therapeutic effectiveness of acupuncture as a means to aid postoperative recovery of gastrointestinal function in patients undergoing thoracoscopic surgery. METHODS: In total, 112 patients aged 18-70 years undergoing thoracoscopic surgery between 15 June 2022 and 30 August 2022 were randomized into two groups. Patients in the acupuncture group (AG) first received acupuncture treatment 4 h after surgery, and treatment was repeated at 24 and 48 h. Patients in the control group (CG) did not receive any acupuncture treatment. Both groups received the same anesthetic protocol. Ultrasound-guided thoracic paravertebral block (TPVB) was performed in the paravertebral spaces between T4 and T5 with administration of 20 mL of 0.33% ropivacaine. All patients received patient-controlled intravenous analgesia (PCIA) after surgery. RESULTS: Median time to first flatus [interquartile range] in the AG was significantly less than in the CG (23.25 [18.13, 29.75] vs 30.75 [24.13, 45.38] h, p < 0.001). Time to first fluid intake after surgery was significantly less in the AG, as compared with the CG (4 [3, 7] vs 6.5 [4.13, 10.75] h, p = 0.003). Static pain, measured by visual analog scale (VAS) score, was significantly different on the third day after surgery (p = 0.018). Dynamic pain VAS scores were lower in the AG versus CG on the first three postoperative days (p = 0.014, 0.003 and 0.041, respectively). CONCLUSION: Addition of acupuncture appeared to improve recovery of postoperative gastrointestinal function and alleviate posteoperative pain in patients undergoing thoracoscopic surgery. Acupuncture may represent a feasible strategy for the prevention of PGD occurrence. TRIAL REGISTRATION NUMBER: ChiCTR2200060888 (Chinese Clinical Trial Registry).

Ultrasound-Guided Transversus Abdominis Plane Blocks Versus Local Infiltration Anesthesia on Postanesthesia Care Unit Pain Control in Patients Undergoing Abdominoplasty.

GOALS/PURPOSE: The goal of this study was to compare ultrasound-guided transversus abdominis plane (TAP) blocks to local infiltration anesthesia with or without blind rectus sheath blocks in patients who underwent abdominoplasty at an outpatient surgery center. METHODS/TECHNIQUE: A retrospective review was conducted of patients who underwent outpatient abdominoplasty performed by the senior surgeon (J.T.L.). Group 1 received local infiltration anesthesia with or without blind rectus sheath blocks between April 2009 and December 2013. Group 2 received surgeon-led, intraoperative, ultrasound-guided, 4-quadrant TAP blocks between January 2014 and December 2021. Outcomes measured were opioid utilization (morphine milligram equivalents), pain level at discharge, and time spent in postanesthesia care unit (PACU). RESULTS: Sixty patients in each of the 2 study groups met the study criteria for a total of 120 patients. The study groups were similar except for a lower average age in group 1. Patients who received TAP blocks (group 2) had significantly lower morphine milligram equivalent requirements in the PACU (3.07 vs 8.93, P = 0.0001) and required a shorter stay in PACU (95.4 vs 117.18 minutes, P = 0.0001). There were no significant differences in pain level at discharge. CONCLUSIONS: Surgeon-led, intraoperative, ultrasound-guided, 4-quadrant TAP blocks statistically significantly reduced opioid utilization in PACU by 65.6% and average patient time in the PACU by 18.5% (21.8 minutes).

High-frequency, high-intensity transcutaneous electrical nerve stimulation compared with opioids for pain relief after gynecological surgery: a systematic review and meta-analysis.

OBJECTIVES: Opioids are important for postoperative analgesia but their use can be associated with numerous side effects. Transcutaneous electrical nerve stimulation (TENS) has been used for acute pain treatment and has dose-dependent analgesic effects, and therefore presents an alternative to intravenous (iv) opioids for postoperative pain relief. The aim of this meta-analysis was to compare high-frequency, high-intensity (HFHI or intense) TENS to iv opioids with regard to postoperative pain intensity, recovery time in the Post Anesthesia Care Unit (PACU) and opioid consumption after elective gynecological surgery. METHODS: We searched Medline, Embase, Web of Science, Cochrane, Amed and Cinahl for RCTs and quasi-experimental studies (2010-2022), and WHO and ClinicalTrials.gov for ongoing/unpublished studies. Meta-analysis and subsequent Trial Sequential Analysis (TSA) was performed for all stated outcomes. Quality of evidence was assessed according to GRADE. RESULTS: Only three RCTs met the inclusion criteria (362 participants). The surgical procedures involved surgical abortion, gynecologic laparoscopy and hysteroscopy. The applied TENS frequency was 80 Hz and intensity 40-60 mA. There was no difference in pain intensity according to Visual Analogue Scale (VAS) at discharge from PACU between the TENS and opioid group (MD VAS -0.15, 95 % CI -0.38 to 0.09) (moderate level of evidence). Time in PACU was significantly shorter in the TENS group (MD -15.2, 95 % -22.75 to -7.67), and this finding was manifested by TSA (high-level of evidence). Opioid consumption in PACU was lower in the TENS group (MD Morphine equivalents per patient mg -3.42, 95 % -4.67 to -2.17) (high-level of evidence). CONCLUSIONS: There was no detectable difference in postoperative pain relief between HFHI TENS and iv opioids after gynecological surgery. Moreover, HFHI TENS decreases recovery time and opioid consumption in PACU. HFHI TENS may be considered an opioid-sparing alternative for postoperative pain relief after gynecological surgery.

Clinical Effect of Ultrasound-Guided Adductor Block on Postoperative Analgesia After Total Knee Replacement.

Objective: To explore the clinical effects of ultrasound-guided adductor block (UGAB) on postoperative analgesia after total knee replacement. Methods: From March 2022 to June 2022, 60 patients in the First Affiliated Hospital of Chongqing Medical University were included. They were divided into control (n = 30) and ultrasonic groups (n = 30). They all received total knee arthroplasty. Before total knee arthroplasty, patients in the control and ultrasonic groups underwent general anesthesia and UGAB, respectively. Visual Analogue Scale (VAS) was used to assess the pain. The time of the first straight leg elevation and the first landing time were recorded. Knee joint function was evaluated. Information about the dosage of tramadol intramuscular injection and the number of times patient-controlled analgesia pump pressing was collected. The serum levels of interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) were detected. Results: Compared with the control group, UGAB increased the rate of muscle contraction and relaxation and total and relaxation after total knee replacement in the ultrasonic group (P < .05). UGAB reduced VAS scores of pain during passive activity after operation (P < .05). UGAB also facilitated the first straight leg lifting time after the operation and the time of the first landing after the operation (P < .05). Meanwhile, UGAB reduced the dose of tramadol and press times of the self-control analgesia pump after operation (P < 0.05). UGAB also suppressed postoperative IL-6 and hs-CRP levels and increased postoperative joint range of motion (P < .05). Conclusion: UGAB promotes early recovery of knee function with high safety in patients undergoing total knee replacement, with reduced postoperative pain and inflammatory reaction.

Fascial plane blocks in children-Scientifically supported or not?

Since the introduction of Fascial Plane Blocks in 2007 there has been an enormous interest and application of Fascial Plane Blocks, evidenced by substantially more than 1000 PubMed items. Despite this gigantic number of publications, also including randomized controlled trials and meta-analyses in children, there is still no clear-cut insight into how much of the purported effect is in fact due to the blockade of nerve structures and how much is merely adding the well-known analgesic and anti-inflammatory effects of the plasma levels of local anesthetics that are achieved with these techniques. Furthermore, Fascial Plane Blocks appear useful only if compared to conventional multi-modal analgesia (no block or placebo) and Fascial Plane Blocks lack the potency to provide surgical anesthesia on their own and appear only to be of value when used for minor-moderate surgery. Despite the huge literature, there has so far not emerged any clinical situations where Fascial Plane Blocks have definitively been shown to be the block of choice, being decisively more effective than other established regional blocks. Lastly, Fascial Plane Blocks may appear as virtually free of complications, but case reports are emerging that point to a real risk for causing local anesthetic systemic toxicity when using Fascial Plane Blocks. This text aims to synthesize the current knowledge base regarding the Fascial Plane Blocks that are relevant to use in the pediatric context. In summary, there does currently not exist any convincing scientific evidence for the continued support for the use of Fascial Plane Blocks in children, except for the rectus sheath block and possibly also the transmuscular quadratus lumborum block.

Is enhanced recovery after surgery essential?

BACKGROUND: The enhanced recovery after surgery (ERAS) method is designed for the patient to recover quickly, have less pain and have a more comfortable period after the surgery; that includes preoperative, intra and postoperative processes. ERAS has been started to be applied in cesarean section surgeries as the patients need to recover quickly. In the literature, there is no study about the results of ERAS in cesarean section about pain scores and complications. OBJECTIVES: It is aimed to compare the results of cesarean section patients using the ERAS method completely in patients who have had cesarean section without meeting some of the postoperative conditions of the ERAS criteria. STUDY DESIGN: It is a prospective study designed as postoperative metoclopramide, enema and routine opioids in group 1, enema and metoclopramide in group 2, metoclopramide only in group 3 and nothing in group 4. Postoperative pain scoring was done by using visual analog scale (VAS). Analysis of variance tests and t tests were used for results. RESULTS: There was no difference between groups according to age, parity, and birth weight. As a result, although there was no difference between the groups in terms of discharge time and complications, the VAS score used in pain scoring was found to be significantly lower in group 3 compared to the other groups (p: 0.000). Only metoclopramide group (group 3) had lowest VAS score. CONCLUSION: It has been revealed that the ERAS procedure does not need to be so detailed in the postoperative period, and the addition of metoclopramide may be sufficient. Since pain can be a subjective factor, other randomized studies are needed in terms of other criteria.

Effectiveness of low power laser in reducing postoperative signs and symptoms after third molar surgery: a triple-blind clinical trial.

The objective of this research was to evaluate the effectiveness of using LPL (Low power laser) to reduce pain, edema, and trismus after impacted lower third molar extraction. A split-mouth randomized triple-blind clinical trial was conducted at the Federal University of Ceará. For inclusion criteria, it was necessary that the patient presented a clear indication for removal of both lower third molars, in addition to both molars being in similar positions. The third molars (38 and 48) were randomly allocated to the test group that received the LPL application protocol, and to the placebo group that received a simulation of the protocol, making a total sample of 44 surgeries. Patients in the test group used an average of 50% of the amount of analgesics that was used by the placebo group, however, there was a statistically significant difference only on days four and five. Regarding trismus, the test group presented wide mouth openings, both at 48 hours and at 7 days after surgery compared to the placebo group, but without a statistically significant difference. For edema, we noted an equilibrium between the test group and the placebo group, but no measurement obtained a statistically significant difference. The use of LPL presented better pain and trismus indicators after complex extractions. The use of LPL is thus indicated as a complementary therapy to reduce postoperative discomfort caused by complex tooth extractions.

[Electrophysiological appropriateness technique based on TCM meridian theory for postoperative pain after urethral reconstruction: A real-world study].

OBJECTIVE: To investigate the clinical efficacy of electrophysiological appropriateness technique (EAT) therapy based on the traditional Chinese medicine (TCM) meridian theory in managing postoperative pain after urethral reconstruction surgery. METHODS: Using the real-world study approach, we enrolled 61 male patients undergoing urethral reconstruction and divided them into a control group (n = 30) and an observation group (n = 31), the former receiving patient-controlled intravenous analgesia (PCIA), while the latter PCIA plus EAT at 4 pairs of acupoints (Hegu, Neiguan, Zusanli and Sanyinjiao bilaterally) and the Ashi point, with 100 mg tramadol hydrochloride given orally as remedial analgesia in both groups in case of postoperative Visual Analogue Scale (VAS) score ≥4. We compared the VAS scores at 4, 12, 24 and 48 hours postoperatively, the dose of cumulative fentanyl used at 48 hours, the number of cases needing remedial analgesia, the time to first flatus and the incidence of adverse reactions between the two groups of patients. RESULTS: The VAS scores were markedly lower in the observation than in the control group at 4, 12, 24 and 48 hours after surgery (P < 0.05), with statistically significant differences in time-dependent effect and interactive effect (P < 0.05). Significant reduction was observed in the doses of cumulative fentanyl (P < 0.05) and remedial tramadol analgesia (P < 0.05), time to first flatus (P < 0.05), and incidence of adverse reactions (P < 0.05) in the observation group in comparison with the controls. CONCLUSION: Electrophysiological therapy based on the TCM meridian theory can safely and effectively alleviate postoperative pain after urethral reconstruction, reduce opioid consumption, and decrease adverse events.

Trends of opioid prescription in cancer patients utilizing telemedicine: a retrospective study.

Aim: Prescribing patterns among healthcare practitioners remain a recurring theme of interest in the opioid crisis. This study aims to provide insight on opioid prescribing patterns for cancer pain in telemedicine and in-person encounters during COVID-19. Materials & methods: A retrospective chart review of 1000 encounters (500 telemedicine and 500 in-person) at an academic tertiary care comprehensive cancer center. Results: On average, overall, significantly higher narcotics (in morphine milligram equivalents [MME]) prescribed for patients receiving telemedicine services. In-person encounters had a significantly higher proportion of narcotic (in MME) increases in subsequent visits. Conclusion: Our institution continues to adapt telehealth services as an additional care venue and deeper insight helps mitigate development of maladaptive opioid prescribing patterns.
