Project description:IntroductionThe aim of this study was to compare the postoperative analgesic effects of ultrasound-guided quadratus lumborum block-2 (QLB-2) and quadratus lumborum block-3 (QLB-3) after cesarean section (C/S) under general anesthesia.MethodThis was a prospective, randomized, double-blind study. A total of 143 term pregnant women with American Society of Anesthesiologists II status, who were scheduled for elective C/S under general anesthesia were randomly separated into QLB-2 and QLB-3 groups. After surgery under standardized general anesthesia, QLBs were performed with 0.3 mL.Kg-1 0.25% bupivacaine in both groups. Patient-controlled analgesia (PCA) devices were used for additional analgesia. The primary outcomes were pain scores evaluated at 0, 2, 6, 12, and 24 hours. In addition, PCA demands, actual delivered tramadol doses, rescue analgesic requirements, anesthesia time, and patient satisfaction were recorded.ResultsA total of 104 patients were analyzed statistically. Pain scores were statistically lower in the QLB-3 group at 2, 6, 12, and 24 hours postoperatively (P = .001). Anesthesia time was longer in the QLB-3 group. Patients who received QLB-3 block demonstrated significantly fewer PCA demands and lower consumption of tramadol (P = .003). Moreover, the first analgesic requirement time was longer along with higher patient satisfaction. In addition, all procedures were performed without any complications and side effects due to PCA were negligible.ConclusionsThis study demonstrated that, although both QLBs were safe and reliable, QLB-3 provides more effective analgesia and patient satisfaction than QLB-2 in C/S.

Project description:Background: Post-operative sore throat (POST) is one of the most common complaints post-endotracheal intubation and can be decreased through various interventions. This study aimed to determine the effect of fluticasone-impregnated versus saline throat packs on the occurrence and severity of POST and voice hoarseness. Methods: This prospective, randomized, double-blinded trial was conducted on patients undergoing nasosinus surgeries at Kasturba Medical College and Hospital. Patients were randomized to groups based on a computer-generated table of random numbers post-intubation after placing a definite length of oropharyngeal packs into group F (fluticasone) who received four puffs of fluticasone furoate-soaked throat packs and group C (control) wherein normal saline-soaked throat packs were used. Determining the incidence of POST and voice hoarseness was the primary outcome; severity of POST and voice hoarseness, patient satisfaction scores at 24 hours post-surgery and adverse events were secondary outcomes. Results: Overall, 86 patients were randomized and 43 patients were included in each group. Incidence of POST (%) and voice hoarseness (%) were 55.8, 55.6, 55.8, 53.4 and 30.2, 28, 28, 28 in group C. Incidence of POST (%) and voice hoarseness (%) were 37.2, 37.2, 37.2, 34.8 and 14, 14, 14,14 in group F at 1, 2, 6 and 24 hours, respectively, however, the p values were not found to be significant at any time interval. There was no significant difference in terms of severity of POST and voice hoarseness, patient satisfaction scores between the groups and there were no reported adverse events. Conclusions: In patients undergoing nasosinus surgery under general anesthesia with endotracheal intubation, fluticasone furoate-impregnated throat packs failed to show any significant reduction in the incidence and severity of POST as well as hoarseness of voice, and even though it was not statistically significant, the fluticasone impregnated group had higher patient satisfaction scores.

Project description:BackgroundAfter laparoscopic abdominal surgery, we aim to evaluate the analgesic efficiency of US-directed bilateral transversus abdominis plane block (TAPB) and quadratus lumborum block (QLB).Methods50 patients aged 18-60 years listed for elective laparoscopic abdomen operation were registered in this study. Cases were randomly allocated into two similar groups: TAPB and QLB groups. The first outcome was the growing morphine consumption on the 1st day postoperatively. The second outcome involved VAS score, first analgesic necessities, and any postoperative complications. Statistical analysis was done with the 2-sample t-test, and Mann-Whitney U testing was utilized to compare medians for skewed end points. Qualitative data were introduced as numbers and percentages, and chi-squared testing was utilized to determine the significance.ResultsThe median cumulative morphine consumptions on the 1st day were high significantly in the TAPB group than in the QLB group (6 mg [6, 9] vs. 3 mg [3, 6], p value ≤0.0001]). The QLB group showed an increase in the median of the time to the first analgesic request in comparison with the TAPB group (17 hours [12, 24] vs. 8 hours [6, 24], p ≤ 0.001). In addition, on the 1st day, the mean VAS scoring at rest was lower in the QLB group.ConclusionIn comparison to the TAPB, the QL block delivers more successful pain relief, has an extended period of analgesic actions, extends interval to the 1st analgesic necessity, is accompanied with lesser morphine consumptions, and may be utilized in multimodal analgesia and opioid-sparing regimens after that laparoscopic operation. This trial is registered with NCT04553991.

Project description:BackgroundThis study aimed to investigate the analgesic efficacy and motor block profile of single-shot transmuscular quadratus lumborum block (QLB) in comparison with those of suprainguinal fascia iliaca block (FIB) in patients undergoing hip arthroplasty.MethodsThis randomized, double-blinded, controlled trial included adult patients undergoing hip arthroplasty under spinal anesthesia. Patients were allocated to one of two groups according to the regional block received: FIB group (n=19) or QLB group (n=17). Both study groups were compared with regard to the duration of analgesia (primary outcome), block performance time, pain during positioning for spinal anesthesia, total morphine consumption in the first postoperative 24-h period, quadriceps muscle power, and static and dynamic visual analog scale.ResultsThirty-six patients were included in the final analysis. Both study groups had comparable durations of analgesia. Postoperative visual analog scale (static and dynamic) values were comparable between the two groups in most readings. The block performance time was shorter in the FIB group. The number of patients with pain during positioning for the subarachnoid block was lower in the QLB group. The total morphine requirement during the first 24 h was marginally lower in the FIB group, whereas the quadriceps motor grade was higher in the FIB group than in the QLB group at 4 h and 6 h after surgery.ConclusionBoth single-shot blocks, namely the suprainguinal FIB and transmuscular QLB, provide effective postoperative analgesia after hip arthroplasty. FIB showed slightly lower 24-h morphine consumption, while QLB showed better quadriceps motor power.Clinical trial registrationThe study was registered at clinical trials registry system before enrollment of the first participant (NCT04005326; initial release date, 2 July 2019; https://clinicaltrials.gov/ct2/show/NCT04005326).

Project description:BackgroundThe quadratus lumborum block (QLB) has recently been used frequently for postoperative analgesia after abdominal surgery. The aim of this study was to investigate the effect of pressure changes between the middle thoracolumbar fascia layers to which the anterior QLB (aQLB) is applied at the level of the sensory block.MethodsA total of 67 patients planned to undergo laparoscopic cholecystectomy were evaluated in the context of this prospective study. Bilateral aQLBs were administered to all patients, and a peripheral nerve block catheter was placed between the psoas and quadratus lumborum muscles. The correlation of interfascial pressures (IFPs) during block application, 30 min intraoperatively, and 30 min postoperatively with the sensory block level was determined as the primary outcome measure. Secondary outcome measures were the sensory block levels 30 min after block application and 30 min postoperatively; visual analog scale scores 30 min and 6, 12, and 24 h postoperatively; and 24 h tramadol consumption.ResultsThe preoperatively and intraoperatively measured IFPs differed significantly between the right and left sides (P < 0.05). The preoperative and postoperative block levels also differed significantly between the right and left sides (P < 0.05). The preoperative and postoperative block levels and preoperatively measured IFPs showed a weakly negative correlation (right: r = 0.374; left: r = 0.470).ConclusionsThe results of this study show that pressure changes between the fasciae may be effective in aQLB application.

Project description:BACKGROUND:The postoperative analgesic effect of transmuscular quadratus lumborum block (QLB-TM) in patients following lower abdominal surgeries has been identified; however, the efficacy of QLB using the lateral approach (QLB-L) is still in debate. Therefore, this retrospective study was conducted to investigate the effect of a single-shot block with QLB-L on postoperative analgesia for patients undergoing percutaneous nephrolithotomy (PCNL). METHODS:The medical information of the patients undergoing PCNL was retrieved from the electronic charter system (Medisystem, Suzhou, China) in our Nanjing Drum Tower Hospital during the period of Jan/2019 to Jun/2019. Among the total of 57 patients, there are 17, 18, and 22 patients subjected to QLB-L, QLB-TM, or routine treatment, respectively. The primary observational parameter was to assess postoperative pain with visual analog scales (VAS) at rest 30?min after extubation, 24?h, and 48?h after surgery, respectively. The secondary observatory endpoints, including the consumption of intraoperative opioids, the cumulative dose of non-steroid anti-inflammatory drugs (NSAIDs) and the incidence of adverse events related to postoperative analgesia, were evaluated as well. RESULTS:The static VAS score at 24?h after surgery and the intraoperative consumption of sufentanil were significantly lower in patients receiving either intervention of QLB-L or QLB-TM as compared with those receiving routine treatment. However, one shot of QLB had no impact on VAS scores at 30?min post-extubation, 48?h after PCNL procedure compared with the patients receiving routine treatment. The percentage of non-ambulatory patients within 24?h post-PCNL was significantly higher in the QLB-TM group compared with the routine treatment group (P?=?0.04). There were no significant differences in the incidence of postoperative nausea and vomit (PONV), itches, respiratory depression, the time for the first defecation, and the length of hospital stay (LOS) among the three groups. CONCLUSIONS:QLB-L procedure may exert as equivalent as QLB-TM in terms of abrogating postoperative pain within 24?h post-surgery and decreasing intraoperative sufentanil consumption in patients undergoing PCNL procedure as well. The caution should be taken to avoid lower extremities weakness in the patients after QLB-TM within the first 24?h post-PCNL procedure.

Project description:BackgroundAchieving optimal analgesia with few side effects is the goal of pain management after cesarean delivery. Intrathecal (IT) morphine is the current standard but ultrasound-guided quadratus lumborum block (QLB) may offer superior pain control with fewer side effects. This study compared the pain-free period after cesarean delivery among parturients who received spinal block with IT morphine, with IT morphine and bilateral QLB, or only bilateral QLB.MethodsParturients having elective cesarean delivery under spinal block were randomized and allocated into IT morphine 0.2 mg with sham QLB (Group IT), IT morphine 0.2 mg and bilateral QLB with 0.25% bupivacaine 25 ml in each side (Group IT+QLB), or bilateral QLB with 0.25% bupivacaine 25 ml in each side (Group QLB). A PCA pump was connected after completion of the QLB or sham block. The first time to PCA morphine requirement was recorded and compared.ResultsEighty parturients were included. Analysis of Group QLB was terminated early because at the second interim analysis, median pain-free period was significantly shorter in Group QLB [hours (95%CI): 2.50 (1.04-3.96) in Group IT vs. 7.75 (5.67-9.83) in IT+QLB vs. 1.75 (0.75-2.75) in QLB (p < 0.001)]. The median (min, max) amount of morphine required during 24 h was 5.5 (0-25) in Group IT vs. 5.0 (0-36) in IT+QLB vs. 17.5 (1-40) mg in Group QLB (p < 0.001). In the final analysis the median pain-free period was 2.50 (1.23-3.77) hours (95%CI) in Group IT (n = 27) vs. 8.02 (5.96-10.07) in IT+QLB (n = 28). (p = 0.027).ConclusionUS-QLB used in conjunction with IT morphine yielded a statistically significant longer median pain-free period compared with standard IT morphine alone. However, QLB alone provided inferior pain control compared with standard IT morphine. When combined with IT morphine, QLB could provide additional analgesic benefit as a part of multimodal analgesic regimen, especially during the early postoperative period.Trial registrationClinicalTrials.gov no.

Project description:IntroductionThe management of postoperative pain following lumbar disc herniation (LDH) surgery is crucial for the quality of recovery. The effectiveness of multimodal analgesia plans increases when interfascial plane blocks are included. This study sought to compare the analgesic efficacy of preoperative ultrasound-guided TLIP (thoracolumbar interfascial plane) blocks and posterior QLBs (quadratus lumborum blocks) in patients undergoing LDH surgery.MethodsPatients undergoing elective LDH surgery under general anesthesia were randomized into two groups: thoracolumbar interfascial plane block (Group T) and posterior quadratus lumborum block (Group Q). Block applications were performed 30 min before anesthesia induction. In the postoperative period, analgesia control was provided with a patient-controlled analgesia device. The patients' 24 h cumulative opioid consumption was examined. Pain scores were evaluated in the 0th, 3rd, 6th, 9th, 12th, and 24th hours.ResultsThe mean 24 h cumulative morphine consumption for patients was statistically insignificant when Groups T and Q were compared (9.14 ± 7.03 mg vs. 8.66 ± 6.58 mg, p = 0.788). Pain scores at rest and during movement as well as morphine consumption were similar between groups in the 0th, 3rd, 6th, 9th, 12th, and 24th hours (p > 0.05).ConclusionsThe study determined that the utilization of TLIP blocks and posterior QLBs prior to anesthesia induction yielded comparable outcomes in terms of reducing postoperative analgesic consumption and enhancing the efficacy of multimodal analgesia in individuals undergoing single-distance lumbosacral spine surgery under general anesthesia.

Project description:Background and aimsIn this study, we aimed to compare the transversus abdominis plan block (TAP) and quadratus lumborum block (QL) efficacy for postoperative analgesia in patients undergoing varicocelectomy under spinal anesthesia.MethodsAmerican Society of Anesthesiologists (ASA) 1 and 2 patients, aged 18-45 years, who underwent varicocelectomy operation under elective conditions, were included. Eighty patients were divided into three groups as TAP group, QL group, and control group by prospective randomization. The patients were operated under spinal anesthesia. At the end of the operation, TAP was applied to the TAP group with a posterior approach using ultrasound (USG) in the supine position. To the QL group, the patient was placed in the lateral decubitus position and the lateral QL was applied via USG. No block type was applied to the control group. Patient-controlled analgesia (PCA) device containing tramadol was administered intravenously at the end of the surgery in all groups. Visual analogue scale (VAS) score was questioned at 0, 2, 4, 6, 8, 10, 12, 18, 24 h in the follow-up of the patients. Intravenous 1 g paracetamol was given over VAS 4. PCA usage time and usage amounts were recorded.ResultsAs a result of comparing the groups according to the VAS scores at all hours were significantly different between the three groups (p < 0.001). There was a significant difference between the groups when comparing the number of PCA bolus administrations (p < 0.001). TAP and QL blocks significantly reduced the number of PCA bolus when compared with the control group (p < 0.001) but the number of PCA bolus was found to be similar between TAP and QL blocks (p > 0.05).ConclusionTAP and QL, which are administered to evaluate the effectiveness of postoperative analgesia in patients undergoing varicocelectomy under spinal anesthesia, are both effective in reducing pain scores and the amount of analgesia consumption.

Project description:ObjectiveAnterior quadratus lumborum block at the lateral supra-arcuate ligament (QLBA) is a new method for postoperative pain relief in patients undergoing abdominal surgery. Perioperative QLBA is effective, but it has not been compared with posterior quadratus lumborum block (QLB2). The present study aims to evaluate the postoperative pain of patients undergoing laparoscopic nephrectomy surgery with QLBA versus QLB2.Methods/designThis study is a randomised, prospective, parallel group, non-inferior trial. All patients undergoing laparoscopic nephrectomy surgery will be randomised 1:1 to the QLBA group or the QLB2 group with general anaesthesia. The objective of the trial is to evaluate the postoperative pain of patients undergoing laparoscopic nephrectomy surgery with QLBA (n=50) versus QLB2 (n=50). The primary outcome for this trial is the Visual Analogue Scale scores at rest and activity (dynamic pain scores are assessed with a cough or a trial to sit up in bed) 2 hours after surgery between patients who receive QLBA versus QLB2. The secondary objectives will be to compare (1) pain at rest and activity 0.5 hour, 2 hours, 24 hours, 48 hours after surgery; (2) the time spent on block operation; (3) the blocked dermatomal coverage 5 min and 15 min after block operation; (4) intraoperative opioid consumption; (5) types and doses of the rescue analgesic after surgery; (6) nausea and vomiting score within 24 hours after surgery; (7) time from the end of surgery to the first onset significant pain; (8) patient satisfaction score.DiscussionClinical experience has supported that QLB is a very effective postoperative analgesic method, and we will answer the following questions in this trial: Will both approaches have the same analgesic effect and duration? Will the QLBA have a non-inferior postoperative analgesic effect compared with QLB2 or the QLBA be able to prolong the duration of analgesia after surgery? The results of this study could have actual clinical applications that could help to reduce postoperative pain and shorten hospital stays.Ethics and disseminationThe study design was approved by the ethical committee of Beijing Chao-Yang Hospital, Beijing, China (2020-ke-321). The trial results will be published in peer-reviewed journals and at conferences.Trial registration numberChiCTR2000035354.
