Project description:IntroductionThe analgesic effect and safety of transversus abdominis plane block (TAPB) is still controversial in various abdominal procedures. Quadratus lumborum block (QLB) has been considered to provide a widespread and long-lasting analgesic effect in gynecological surgeries. However, the analgesic effects of these two techniques in patients with extreme obesity undergoing laparoscopic sleeve gastrectomy (LSG) are still unknown.MethodsA total of 225 patients with obesity were randomly assigned to group TAPB (n = 76, 30 ml 0.33% ropivacaine with dexmedetomidine 1 μg kg-1), group QLB (n = 76, 30 ml 0.33% ropivacaine with dexmedetomidine 1 μg kg-1), or general anesthesia alone (GA, n = 73, 30 ml 0.9% saline). During the 48-h postoperative period, patients received continuous intravenous patient-controlled analgesia (PCA) containing sufentanil 2 μg kg-1, dexmedetomidine 2 μg kg-1, and granisetron 3 mg. The scores of visual analogue scale (VAS) in surgical incision and viscera, considering as the primary outcomes, were continuously recorded at postoperative 0, 0.5, 1, 2, 6, 12, 24, 48 h and discharge.ResultsComparing with patients in the GA group, VAS scores of incision and viscera were consistently reduced during the initial 6-12 h after LSG in TAPB and QLB groups, and they received less propofol and remifentanil (P < 0.001) as well. In the QLB group, patients had longer duration for the first rescue analgesia, and fewer requirements of the rescue analgesia within 24 h than the GA group (P < 0.05). In addition, there were fewer PCA requirements in QLB group than GA and TAPB groups (P < 0.05).ConclusionsUltrasound-guided transversus abdominis plane block and quadratus lumborum block could provide comparable analgesic effects for a laparoscopic sleeve gastrectomy in obese patients.Trial registrationChinese Clinical Trial Registry; ChiCTR1800019236.

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: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.
