Purpose The study aimed to evaluate the efficacy of ultrasound-guided pudendal nerve block (PNB) versus local anesthetic infiltration (LAI) in managing the pain. Methods This is a prospective, randomized, double-blinded trial, 78 patients undergoing procedure for prolapse and hemorrhoids (PPH) were randomly allocated to receive either ultrasound-guided PNB or LAI. Primary outcomes were postoperative pain scores using the visual analogue scale at multiple time points within the first 48 h. Secondary outcomes included tramadol consumption, incidence of postoperative nausea and vomiting, and quality of recovery-15 (QoR-15) scores. Results The trial ultimately involved 71 patients. Results showed that the PNB group had significantly lower pain scores at 6, 12, and 18 h postoperatively compared with the LAI group (all P  < 0.01), with no significant differences noted at 24 and 48 h. PNB group also had fewer patients requiring supplemental tramadol (5/36) than the LAI group (12/35) ( P  < 0.05) and experienced a delayed onset of pain (13.83 ± 11.21 h vs. 6.94 ± 2.88 h; P  < 0.001). Furthermore, the incidence of anal sphincter spasms was lower in the PNB group (5/36) compared with the LAI group (12/35) ( P  < 0.04). QoR-15 scores at 24 h postoperatively were significantly higher in the PNB group (119.11 ± 5.87) compared with the LAI group (112.03 ± 7.04) ( P  < 0.05), indicating a better early recovery experience. Patient satisfaction was higher in the PNB group (28/36 vs. 22/35, P  < 0.05). Conclusion Ultrasound-guided PNB was more effective than LAI in pain control and recovery quality. It can be considered an effective method for postoperative pain management in patients undergoing PPH surgery.

BackgroundRecovery after CRS-HIPEC influenced by several factors, including pain and opioid consumption. We hypothesized that 4Q-TAP blocks provide not inferior quality of recovery compared with TEA after CRS-HIPEC. We conducted a randomized, controlled trial to determine whether 4-quadrant transversus abdominis plane (4Q-TAP) block analgesia was noninferior to thoracic epidural (TEA) among patients who underwent cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS HIPEC).MethodsPatients 18 years or older who underwent a CRS-HIPEC surgery were randomly assigned to have either TEA or 4Q-TAP blocks. The primary outcome of this study was the change in quality of recovery 2 days after surgery. Secondary outcomes included quality of recovery on Days 1, 3, 5, 7, 10, and 30 postoperatively, opioid consumption, pain intensity, length of stay, and postoperative complications. Analyses were performed on a per-protocol basis.ResultsSixty-eight patients were included in the analysis. The difference between 4Q-TAP and TEA in the mean QoR-15 change from surgery at postoperative Days 1, 2, and 3 was 0.80 (P = 0.004), −4.5 (P = 0.134), and 3.4 (P = 0.003), respectively. All differences through postoperative day 30 were significantly within the noninferiority boundary of −10 except at postoperative Day 2 (P = 0.134). Length of stay, opioid-related adverse events, and frequency and grade of complications were not significantly different between TEA and 4Q-TAP patients.ConclusionsDespite the significantly higher use of opioids after CRS-HIPEC in patients with 4Q-TAP blocks, their short-term quality of recovery was not inferior to those treated with TEA. Patients undergoing CRS-HIPEC can be effectively managed with 4Q-TAP blocks.

Background/Objectives: The aim of this study was to evaluate if platelet-rich plasma (PRP) application into the wound during cesarean delivery improves wound healing and reduces pain in the postoperative period. Materials and Methods: A total of 46 patients undergoing cesarean section (CS) were included in this single-blind placebo-controlled intervention study: 23 women in the PRP group and 23 in the placebo group. Every patient was asked to evaluate pain by using the Visual Analogue Scale (VAS) immediately after surgery, as well as 6 and 12 h after the surgery. The use of analgetics was also recorded. The postoperative scar was assessed using the Patient and Observer Scar Assessment Scale (POSAS). Results: There was no case of wound dehiscence in either group. Significant differences between the groups in the scar quality assessment were detected in both patient and doctor POSAS results on days 8, 30 and 90 after surgery in the favor of the PRP group. There was no difference in the pain intensity assessment on the VAS recorded after surgery, but PRP patients required fewer paracetamol doses per day than the control group. Conclusions: PRP application during CS significantly improved wound healing in both short- and long-term assessment. Although it did not influence postoperative pain intensity, it may reduce the use of analgetics after surgery.

This study aims to evaluate the efficacy of the ozone and laser application in the management of pain, swelling, and trismus after third-molar surgery. Sixty consecutive patients with asymptomatic impacted mandibular third molars were recruited into the study. Patients were randomized into three treatment groups of 20 patients each: two study groups (group 1 = low-level laser therapy (LLLT), group 2 = ozone therapy) and a control group (no-LLLT or ozone therapy). Twenty teeth extractions were performed in each group. Evaluations of postoperative pain, the number of analgesics tablets taken, trismus, swelling, and quality of life (Oral Health Impact Profile-14 questionnaire) were made. The sample consisted of 28 female and 32 male patients, whose total mean age was 23.5 ± 3.4 (range, 18–25) years. The pain level and the number of analgesics tablets taken were lower in the ozonated and LLLT applied groups than in the control group. This study showed that ozone and low power laser therapies had a positive effect on the patients’ quality of life. Trismus in the LLLT group was significantly less than in the ozonated and control groups ( p  = 0.033). Ozone application showed no superiority in regards of postoperative swelling; however, LLLT group had significantly lower postoperative swelling. This study demonstrates that ozone and laser therapies are useful for the reduction of postoperative pain and they increase quality of life after third-molar surgery. Although the ozone therapy had no effect on postoperative swelling and trismus after surgical removal of impacted lower third molars, LLLT had a positive effect.

Erector spinae plane (ESP) block is a novel regional anesthesia technique and gaining importance for postoperative pain management. Since it was first described, the clinicians wonder if this new simple technique can replace paravertebral block (PVB). We aimed to compare the postoperative analgesic effect of ESP block and PVB with a control group in breast surgeries. Randomized controlled trial. Operating room. Seventy-five ASA I–II patients aged 25–65, who were scheduled to go under elective unilateral breast surgery for breast cancer were included to the study. Patients were randomized into three groups as ESP, PVB, and Control group. Ultrasound (US) guided ESP block and PVB with 20 ml 0.25% bupivacaine was done preoperatively to the patients according to their groups. All patients were provided with iv patient-controlled analgesia device for postoperative analgesia. Morphine consumptions and numeric rating scale (NRS) scores for pain were recorded at 1st, 6th, 12th and 24th hours postoperatively. There was a statistically significant difference between ESP and Control groups (p < 0,001) and between PVB and Control groups (p < 0,001), while there was no difference between ESP and PVB groups (p > 0,05) for 24-hour morphine consumptions. There was a significant difference between PVB and Control groups for NRS at postoperative 1st and 6th hour (p = 0.018 and p = 0.027 respectively). This study has shown that US guided ESP block and PVB provided adequate analgesia in patients undergoing breast surgery and have an opioid sparing effect by reducing morphine consumption. Clinical Trials Registry: NCT03480958. •ESP block provides effective analgesia in breast surgery.•ESP block has lower risk of complications compared to TPV block.•Both ESP block and TPV block have a similar analgesic effect in breast surgery.

ObjectivesTo investigate the anaesthetic and analgesic effect of multipoint transcutaneous electrical acupuncture stimulation (TEAS) during supratentorial tumour resection for postoperative recovery and side effects.MethodsIn a blinded clinical trial, 92 patients scheduled for supratentorial craniotomy under general anaesthesia were randomly allocated into either a multipoint TEAS (n=46) or a sham TEAS group (n=46). All patients received total intravenous anaesthesia (TIVA) with propofol and sufentanil. The target concentration of sufentanil was adjusted and recorded according to mean arterial pressure (MAP), heart rate (HR) and bispectral index (BIS). Patients in the TEAS group received TEAS 30 min before anaesthesia induction and this was maintained throughout the operation at four pairs of acupuncture points. Postoperative pain, recovery and side effects were evaluated.ResultsEighty-eight patients completed the study. Continuous monitoring of MAP, HR and BIS showed stable values with no significant differences between the two groups (p>0.05). Sufentanil target plasma concentration in TEAS patients was significantly lower at some time points during supratentorial craniotomy, and total sufentanil consumption was significantly higher in the sham group (p<0.05). Postoperative recovery and pain were significantly improved by TEAS (p<0.001), without the postoperative side effects.ConclusionsMultipoint TEAS at both proximal and distal points combined with TIVA can significantly decrease intraoperative sufentanil requirements, increase pain relief on postoperative day 1 and improve postoperative recovery of patients during supratentorial tumour resection, with no significant increase of side effects. These findings suggest that multipoint TEAS may be clinically effective as an adjunct to analgesia in intraoperative anaesthesia and postoperative pain treatment and may speed recovery.Trial registration numberChinese Clinical Trial Registry (registration number ChiCTR-TRC-10001078).

AbstractObjectiveTo investigate the effects of one and two doses of intravenous dexamethasone in patients after total knee arthroplasty.DesignRandomised, blinded, placebo controlled trial with follow-up at 90 days.SettingFive Danish hospitals, September 2018 to March 2020.Participants485 adult participants undergoing total knee arthroplasty.InterventionA computer generated randomised sequence stratified for site was used to allocate participants to one of three groups: DX1 (dexamethasone (24 mg)+placebo); DX2 (dexamethasone (24 mg)+dexamethasone (24 mg)); or placebo (placebo+placebo). The intervention was given preoperatively and after 24 hours. Participants, investigators, and outcome assessors were blinded. All participants received paracetamol, ibuprofen, and local infiltration analgesia.Main outcome measuresThe primary outcome was total intravenous morphine consumption 0 to 48 hours postoperatively. Multiplicity adjusted threshold for statistical significance was P<0.017 and minimal important difference was 10 mg morphine. Secondary outcomes included postoperative pain.Results485 participants were randomised: 161 to DX1, 162 to DX2, and 162 to placebo. Data from 472 participants (97.3%) were included in the primary outcome analysis. The median (interquartile range) morphine consumptions at 0-48 hours were: DX1 37.9 mg (20.7 to 56.7); DX2 35.0 mg (20.6 to 52.0); and placebo 43.0 mg (28.7 to 64.0). Hodges-Lehmann median differences between groups were: −2.7 mg (98.3% confidence interval −9.3 to 3.7), P=0.30 between DX1 and DX2; 7.8 mg (0.7 to 14.7), P=0.008 between DX1 and placebo; and 10.7 mg (4.0 to 17.3), P<0.001 between DX2 and placebo. Postoperative pain was reduced at 24 hours with one dose, and at 48 hours with two doses, of dexamethasone.ConclusionTwo doses of dexamethasone reduced morphine consumption during 48 hours after total knee arthroplasty and reduced postoperative pain.Trial registrationClinicaltrials.gov NCT03506789.

The aim of this study was to evaluate the efficacy of low-power of 940-nm diode laser on post-operative pain after undisplaced flap surgery. This randomized clinical trial study was conducted using a split-mouth design. The study participants comprised 30 patients who needed periodontal flap surgery for periodontal pockets on the same tooth on both sides of the mandible. One side of the mandible was subjected to undisplaced flap surgery plus treatment with a 940-nm diode laser, and on the contralateral side, the surgery was conducted without applying the laser. Patients received anti-inflammatory medication and analgesics after surgery. The patients were asked to report the number of analgesics they took and the pain they experienced each night for 1 week using a visual analogue scale. An independent-sample t test was used to compare the results between the two groups. Patients reported less pain on days 2, 3, 4, 5, 6, and 7 after surgery in the laser-treated group (p < 0.05). Furthermore, fewer analgesics were used in this group on days 3, 4, 5, 6, and 7 following the surgery (p < 0.05). The 940-nm diode laser with the settings used in this study could significantly reduce pain and the number of analgesics taken by patients after undisplaced flap surgery.
