[PMID: 39019211 DOI: 10.1016/j.ajogmf.2024.101433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 06/27/2024] [Accepted: 07/04/2024] [Indexed: 07/19/2024]
Abstract
BACKGROUND Improved pain control after cesarean section remains a challenging objective. Although both the lateral quadratus lumborum block (L-QLB) and acupuncture have been reported to provide superior postoperative analgesia after cesarean section when compared to placebo, the efficacy of these techniques has never been compared head-to-head. OBJECTIVE This study was conducted to investigate the comparative analgesic efficacy of L-QLB and acupuncture following elective cesarean section. STUDY DESIGN In this prospective, randomized, controlled clinical trial, a total of 190 patients with singleton-term pregnancies scheduled for cesarean section under spinal-epidural anesthesia were enrolled. Patients were randomized 1:1 to acupuncture group or L-QLB group. L-QLB group received bilateral L-QLB with 0.33% ropivacaine and sham acupuncture, acupuncture group received transcutaneous electrical acupoint stimulation and press needle therapy, and sham L-QLB. All patients received the standard postoperative pain treatment. The primary outcome was pain scores on movement at 24 hours. Secondary endpoints included pain scores in the first 48 hours postoperatively, patient-controlled intravenous analgesia (PCIA) demands, analgesia-related adverse effects, postoperative complications, QoR-15, the time to mobilization, and gastrointestinal function. RESULTS Median (interquartile range [range]) pain scores at 24 hours on movement were similar in patients receiving acupuncture or L-QLB (3 [2-4] vs 3 [2-4], respectively; P=.40). PCIA consumption and pain scores within 48 hours postoperatively also showed no difference between the two groups. The acupuncture improved QoR-15 scores at 24 and 48 hours postoperatively (P<.001), as well as shortened the time to first flatus (P=.03) and first drinking (P<.001) compared to L-QLB. In addition, the median time to mobilization in the L-QLB group was markedly prolonged compare with acupuncture group (17.0 [15.0-19.0] hours vs 15.3 [13.3-17.0] hours, estimated median difference, 1.5; 95% CI, 1-2; P<.001). CONCLUSION As a component of multimodal analgesia regimen after cesarean section, acupuncture did not lower postoperative pain scores or reduce analgesic medication consumption compared to L-QLB.

Abstract
INTRODUCTION Postoperative pain management is crucial for patient recovery with Quadratus Lumborum Block (QLB) and Transversus Abdominis Plane Block (TAPB) emerging as potential techniques. We aimed to compare the analgesic efficacy of QLB and TAPB in patients undergoing inguinal hernia repair. METHODS We performed a systematic review of Cochrane, EMBASE, and MEDLINE databases to identify randomized controlled trials comparing QLB and TAPB in patients undergoing inguinal hernia repair. Outcomes included postoperative pain and opioid consumption. Statistical analysis was performed using RevMan 5.4. The review protocol was registered at PROSPERO (CRD42023445513). RESULTS We included five RCTs encompassing 255 patients. QLB was associated with a significant decrease in postoperative pain (MD -0.45; 95% CI -0.75 to -0.14; and p = 0.004; I2 = 94%). However, we found no difference in 24-h opioid consumption between QLB and TAPB groups. CONCLUSION QLB may offer superior pain reduction. However, its effect on opioid consumption remains unclear.

Abstract
Background This study assessed the postoperative analgesic efficacy and safety of the quadratus lumborum block (QLB) in pediatric patients. Methods Electronic databases were searched for studies comparing the QLB to conventional analgesic techniques in pediatric patients. The primary outcome was the need for rescue analgesia 12 and 24 hours after surgery. Secondary outcomes covered the Face-Legs-Activity-Cry-Consolability Scale (FLACC) scores at various time points; parental satisfaction; time to the first rescue analgesia; hospitalization time; block execution time; block failure rates, and adverse events. Results Sixteen randomized controlled trials were analyzed involving 1,061 patients. The QLB significantly reduced the need for rescue analgesia both at 12 and 24 hours after surgery (12 hours, relative risk [RR]: 0.45; 95% confidence interval [CI]: 0.01, 0.88; 24 hours, RR: 0.51; 95% CI: 0.31, 0.70). In case of 24 hours after surgery, type 1 QLB significantly reduced the need for rescue analgesia (RR: 0.56; 95% CI: 0.36, 0.76). The QLB also exhibited lower FLACC scores at 1 hour (standardized mean difference [SMD]: -0.87; 95% CI: -1.56, -0.18) and 6 hours (SMD: -1.27; 95% CI: -2.33, -0.21) following surgery when compared to non-QLB. Among QLBs, type 2 QLB significantly extended the time until the first rescue analgesia (SMD: 1.25; 95% CI: 0.84, 1.67). No significant differences were observed in terms of parental satisfaction, hospitalization time, block execution time, block failure, or adverse events between QLB and non-QLB groups. Conclusions The QLB provides non-inferior analgesic efficacy and safety to conventional methods in pediatric patients.

Abstract
ESP block (ESPB) and posterior Quadratus Lumborum Block (pQLB) have been proposed as opioid-sparing techniques for the management of pain after abdominal surgery. Between December 2021 and October 2022, we conducted a retrospective comparative study at the delivery suite of Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, Italy, to compare the efficacy of ESPB and pQLB in preventing postoperative pain after an elective caesarean section (CS). The primary outcome was total morphine consumption in the first 24 h. Secondary outcomes were time to first opioid request; Numerical Pain Rating Scale (NPRS) at 0, 2, 6, 12 and 24 h; vital signs; adverse events. Fifty-two women were included. The total cumulative dose of morphine was not significantly different between the two groups of patients (p = 0.897). Time to first dose of morphine, NPRS values and haemodynamic parameters were not statistically different between the two groups. NPRS values significantly increased (p < 0.001) at the different time intervals considered. The need for rescue doses of morphine was lower in the ESPB group compared to the pQLB group (hazard ratio of 0.51, 95% CI (0.27 to 0.95), p = 0.030). No adverse event was reported. ESPB seems to be as effective as pQLB in providing analgesia after CS.

Abstract
OBJECTIVES Various approaches to quadratus lumborum block (QLB) have been found to be an effective analgesic modality after cesarean delivery (CD). However, the evidence for the superiority of any individual approach still needs to be demonstrated. Therefore, we conducted this network meta-analysis to compare and rank the different injection sites for QLB for pain-related outcomes after CD. MATERIALS AND METHODS PubMed, EMBASE, SCOPUS, and the Cochrane Central Registers of Controlled Trials (CENTRAL) were searched for randomized controlled trials (RCTs) evaluating the role of any approach of QLB with placebo/no block for post-CD pain. The primary outcome was parenteral consumption of morphine milligram equivalents in 24 postoperative hours. The secondary end points were early pain scores (4 to 6 h), late pain scores (24 h), adverse effects, and block-related complications. We used the surface under cumulative ranking probabilities to order approaches. The analysis was performed using Bayesian statistics (random-effects model). RESULTS Thirteen trials enrolling 890 patients were included. The surface under cumulative ranking probability for parenteral morphine equivalent consumption in 24 hours was the highest (87%) for the lateral approach, followed by the posterior and anterior approaches. The probability of reducing pain scores at all intervals was highest with the anterior approach. The anterior approach also ranked high for postoperative nausea and vomiting reduction, the only consistent reported side effect. DISCUSSION The anterior approach QLB had a superior probability for most patient-centric outcomes for patients undergoing CD. The findings should be confirmed through large RCTs.

Abstract
BACKGROUND The caudal route is a common approach for postoperative analgesia; however, it is associated with limited duration of action. The quadratus lumborum block (QLB) may produce prolonged postoperative analgesia. Therefore, this study aimed to compare the postoperative analgesic efficacy of the ultrasound-guided caudal block with that of the ultrasound-guided transincisional QLB (TiQLB) in pediatric patients undergoing open renal surgery. METHODS Forty patients of both sexes, aged 2-11 years, were randomly assigned to receive either caudal analgesia with 1.25 ml/kg of bupivacaine 0.2% (Caudal group; n = 20) or a QLB with 0.5 ml/kg of bupivacaine 0.2% (TiQLB group; n = 20) in addition to standard general anesthesia. Time to first analgesia was the primary outcome. Total analgesic consumption in the first 24 h postoperatively, pain scores, and the incidence of side effects were the secondary outcomes. RESULTS The mean time to first analgesic requirement was significantly longer in the TiQLB group than in the Caudal group (18.8 ± 5.1 vs. 6.7 ± 0.7 h, P < 0.001). Total ketorolac consumption and pain scores were significantly lower in the TiQLB group (P < 0.001). A few cases of mild postoperative nausea and vomiting were noted among patients in both groups; however, the difference was not statistically significant. No incidence of pruritus, shivering, or respiratory depression was noted. CONCLUSIONS Analgesia after the ultrasound-guided TiQLB with bupivacaine was superior to that after the ultrasound-guided caudal block, with similar side effects.

Abstract
Aim: To study the efficacy of quadratus lumborum block (QLB) and transversus abdominis plane (TAP) in laparoscopic nephrectomy patients. Materials & methods: We conducted a meta-analysis of randomized controlled trials for QLB and/or TAP technique compared with each other or a control. Results: Direct analysis of 24 h post-op pain score at rest for each compared with control showed significant reduction, QLB (mean differences [MD] [95% CI]: -1.12 [-1.87,-0.36]; p = 0.004) and TAP (MD [95% CI]: -0.36 [-0.59, -0.12]; p = 0.003). With movement both were respectively lower than control QLB (MD [95% CI]: -1.12 [-1.51, -0.72]; p = <0.0001) and TAP (MD [95% CI]: -0.50 [-0.95, -0.05]; p = 0.03). Moreover, QLB demonstrated less risk 24 h of post-op nausea vomiting (PONV) versus control (PONV; risk ratios [RR] [95% CI]: 0.64 [0.45,0.90]; p = 0.01). Conclusion: TAP and QLB reduce pain scores compared with control, whereas only QLB reduces PONV compared with control.

Abstract
Ultrasound-guided (US-guided) loco-regional anesthesia can provide significant analgesia and anesthetic-sparing effects when used in rabbits. The aims of this study were to investigate the thoraco-lumbar anatomy of the rabbits, particularly the quadratus lumborum (QL) muscle, to design an appropriate US-guided quadratus lumborum block (QLB) specific for rabbits, and to define the most adequate volume of injectate required to consistently cover the ventral branches of T11 to L3 without affecting the pelvic limb innervation (L4, L5 and L6). Sixteen adult rabbit cadavers were included in the study. After randomization, four different volumes of injectate (0.1 mL/kg, 0.2 mL/kg, 0.3 mL/kg and 0.4 mL/kg) were tested, with these volumes additionally randomized to two sites of injection (right or left QL fascia). An ultrasound-guided QLB was performed with a solution of lidocaine, iodinated contrast and tissue dye (in a proportion of 3:1:1 volume, respectively), with subsequent computed tomography (CT) and anatomical dissection, to evaluate the spread of the injectate. In all but one case, the US-guided QLB performed with a dorsolateral approach using 0.3 mL/kg was adequate, while a dose of 0.4 mL/kg consistently reached the targeted nerves but also extended to L4 and caudally. This may suggest that an injectate volume of 0.3 mL/kg may be the most appropriate to produce adequate spread while not affecting pelvic limb innervation.

Abstract
Various techniques have been formulated to reduce pain and ensure early recovery after surgery, as these are major concerns among surgeons, anesthesiologists, and patients. Erector spinae plane block (ESPB), the injection of local anesthetic into the fascial plane, is a simple and novel analgesia technique widely used due to its minimal risk of complications. ESPB has been tried in various surgeries; however, no study has reported its use in colorectal surgery. This study investigated whether ESPB could promote early recovery following laparoscopic colorectal surgery (LCS) by reducing opioid consumption and pain intensity. After randomization into the ESPB or control groups, an ultrasound-guided ESPB was performed at the thoracic 10th-11th level with 40 mL of 0.25% bupivacaine or normal saline. The ESPB group used less fentanyl during the initial 24 h after surgery (P = 0.004) and experienced less pain (P < 0.05 at all-time points) than the control group. The time to the first ambulation and the length of hospital stay were shorter in the ESPB group than in the control group (P = 0.015 and P = 0.008, respectively). In conclusion, ESPB could promote early recovery by reducing opioid consumption and pain intensity in patients receiving LCS.

Abstract
BACKGROUND Cesarean section is becoming increasingly common. Well-managed postoperative analgesia improves patient comfort while encouraging early ambulation and breastfeeding. The analgesic efficacy of transversalis facial plane block (TFPB) vs. anterior quadratus lumborum block (QLB) was compared in this study. METHODS We analyzed the data of 49 pregnant women (gestation, ≥ 37weeks; age, 18-45years) scheduled for elective cesarean delivery (CD) under general anesthesia. They were randomly divided into TFPB and anterior QLB groups. All blocks were administered bilaterally with 25mL of 0.25% bupivacaine under ultrasound guidance prior to extubation. Postoperative morphine consumption and numerical rating scale (NRS) pain scores (static and dynamic [during coughing]) were recorded at 1, 3, 6, 9, 12, 18, and 24h. RESULTS There was no difference in postoperative morphine consumption between the groups at the third, sixth, and ninth hours, but the anterior QLB group consumed less morphine at the 12th, 18th, and 24th hours. Except for the first hour, resting and dynamic NRS scores were comparable between the groups. The first-hour resting and dynamic NRS scores were lower in the TFPB group (resting NRS, anterior QLB group, median [interquartile range], 2 [2-3] vs. TFPB group, 2 [0-2], p = 0.046; dynamic NRS, anterior QLB group, median [interquartile range], 3 [2-4] vs. TFPB group 2 [0-3], p = 0.001). CONCLUSIONS In patients undergoing CD, anterior QLB decreased morphine consumption in the late period (9-24h) compared to TFPB, while pain scores were similar between both groups. The reduction in morphine consumption was statistically significant, but not clinically significant.

Abstract
The QL block is a high-level locoregional anesthesia technique, which aims to provide analgesia to the abdomen. Several approaches of the QL block have been studied to find out which one allows a greater distribution of the injectate. The aim of this study is to compare the traditional interfascial QL block (IQL) with a new latero-ventral approach (LVQL). We hypothesize that this new approach could be safer and easier to perform, since the injectate is administered more superficially and further away from vital structures. Our second objective is to assess whether a higher volume of injectate (0.6 mL/kg) could reach the ventral branches of the last thoracic nerves, leading to a blockade of the cranial abdomen. Six thawed canine cadavers (12 hemiabdomens) were used for this purpose. Both approaches were performed in all cadavers. A combination of methylene blue/iopromide was administered to each hemiabdomen, randomly assigned to the LVQL or IQL. No differences were found regarding the ease of perform the LVQL with respect to IQL. The results show that both techniques reached the ventral branches from L1 to L3, although only the IQL consistently stained the sympathetic trunk (5/6 IQL vs. 1/6 LVQL). The use of a higher volume did not enhance a more cranial distribution of the injectate.

Abstract
The decrease in quadriceps strength after anterior quadratus lumborum block (AQLB) has not been quantified. This prospective cohort study investigated the incidence of quadriceps weakness after AQLB. We enrolled patients undergoing robot-assisted partial nephrectomy, and AQLB was performed at the L2 level with 30 mL of 0.375% ropivacaine. We evaluated each quadriceps' maximal voluntary isometric contraction using a handheld dynamometer preoperatively and postoperatively at 1 and 4 days. The incidence of muscle weakness was defined as a 25% reduction in muscle strength compared with the preoperative baseline, and "muscle weakness possibly caused by nerve block" was defined as a 25% reduction compared with the non-block side. We also assessed the numerical rating scale and quality of recovery-15 scores. Thirty participants were analyzed. The incidence of muscle weakness compared with preoperative baseline and the non-block side was 13.3% and 30.0%, respectively. Patients with a numerical rating scale ≥ 4 or quality of recovery-15 score < 122, which was classified as moderate or poor, had decreased muscle strength with relative risks of 1.75 and 2.33, respectively. All patients ambulated within 24 h after surgery. The incidence of quadriceps weakness possibly caused by nerve block was 13.3%; however, all patients could ambulate after 1 day.

Abstract
BACKGROUND Duodenum-preserving pancreatic head resection (DPPHR) is the choice of surgery for benign or low-grade malignant tumors of the pancreatic head. Laparoscopic DPPHR (LDPPHR) procedure can be improved by preoperative 3D model reconstruction and the use of intravenous indocyanine green fluorescent before surgery for real-time navigation with fluorescent display to guide the surgical dissection and prevention of from injury to vessels and biliary tract.
CASE SUMMARY Here we report the successful short- and long-term outcomes after one year following LDPPHR for a 60-year lady who had an uneventful recovery and was discharged home one week after the surgery.
CONCLUSION There was no bile leakage or pancreatic leakage or delayed gastric emptying. The histopathology report showed multiple cysts in the pancreatic head and localized pancreatic intraepithelial tumor lesions. The resected margin was free of tumor.

Abstract
Purpose Many studies confirmed that several approaches of quadratus lumborum block (QLB) were superior to transversus abdominis plane block (TAPB) in reducing opioid consumption during postoperative period. As a new QLB approach at the lateral supra-arcuate ligament (QLB-LSAL), the analgesic efficacy and safety in patients undergoing open hepatectomy are still unknown. This study aims to compare postoperative analgesia between the blocks in open hepatectomy. Patients and Methods Sixty-two patients undergoing open hepatectomy were enrolled and randomly allocated into the QLB-LSAL group (group Q) and the subcostal TAPB group (group T). Preoperatively, patients received ultrasound-guided bilateral QLB-LSAL or subcostal TAPB with injection of 0.5% ropivacaine (a total volume of 40 mL). The primary outcome was cumulative total morphine equivalent consumption in the first postoperative 24 h. Other outcomes included numerical rating scale (NRS) scores at rest and coughing, cumulative total morphine equivalent consumption at 2, 6, 12, 48 h, Quality of Recovery-15 (QoR-15) scores, time to first patient-controlled intravenous analgesia (PCIA) request, time to first ambulation and adverse effects. Results The cumulative total morphine equivalent consumption in group Q was decreased significantly at all postoperative time points (P < 0.01). The postoperative NRS scores at rest and coughing in group Q were lower than those in group T at all postoperative time points except 48 h (P < 0.05). A significant increase was also observed in the QoR-15 scores among patients in group Q. Time to first PCIA request was significantly prolonged in group Q than in group T, and time to first ambulation was shortened. Adverse effects showed no statistical significance between the two groups. Conclusion Compared with subcostal TAPB, preoperative bilateral QLB-LSAL provided superior analgesic properties and promoted early postoperative recovery quality in patients undergoing open hepatectomy.

Abstract
INTRODUCTION The 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. METHOD This 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. RESULTS A 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. CONCLUSIONS This 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.

Abstract
Purpose We hypothesized that posterior quadratus lumborum block would reduce postoperative opioid consumption and improve the quality of recovery in patients undergoing sutureless laparoscopic partial nephrectomy. Materials and methods The study included 60 patients, ages 18−65 with American Society of Anesthesiologists scores of I-II scheduled for elective sutureless laparoscopic partial nephrectomy. Before general anesthesia, 60 participating patients were randomly allocated to receive a 30-ml injection posterior to the quadratus lumborum muscle with either 0.375% ropivacaine (n = 30) or normal saline (n = 30). The primary outcomes included cumulative opioid consumption within 12 h postoperatively and quality of postoperative recovery at 48 h. Secondary outcomes included the Numerical Rating Scale (NRS), opioid consumption by period, first time to press the analgesic pump, number of patients needing rescue analgesia, blood glucose and cortisol concentrations, early postoperative recovery indicators, and adverse events. Results There were 48 patients included in the final analysis. The intervention group had lower cumulative consumption of sufentanil within 12 h postoperatively and higher quality of postoperative recovery scores at 48 h postoperatively compared with the control group (p < 0.001). The NRS at resting and movement of the intervention group was lower at 0 h, 6 h, and 12 h after surgery than in the control group (p < 0.05). At prespecified intervals (0 to 2 h, 2 to 6 h, 6 to 12 h, 12 to 24 h, and 24 to 48 h) after surgery, the intervention group had lower consumption of sufentanil compared with the control group (p < 0.05). The intervention group took longer to press the analgesic pump for the first time within 48 h after surgery compared with the control group (p < 0.001). The postoperative blood glucose and cortisol concentrations in the intervention group were lower than in the control group (p < 0.05). The times to first excretion, ambulation, and discharge were shorter in the intervention group compared with the control group (p < 0.05). There was no significant difference in adverse events between the two groups. Conclusions Our trial demonstrated that patients who received posterior quadratus lumborum block had significantly lower opioid consumption within 12 h postoperatively and had a better quality of recovery at 48 h postoperatively. Therefore, we recommend posterior quadratus lumborum block as an option for postoperative analgesia in patients undergoing sutureless laparoscopic partial nephrectomy.

Abstract
Background and Aims In 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. Methods American 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. Results As 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). Conclusion TAP 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.

Abstract
The quadratus lumborum block (QLB) is reported to reduce pain and improve function following total hip arthroplasty; however, randomised controlled trials evaluating the benefits of adding this block to general or spinal anaesthesia in this population are conflicting. We performed a systematic review seeking randomised controlled trials investigating QLB benefits for total hip arthroplasty, stratifying comparisons regarding the addition of QLB to either general or spinal anaesthesia. The primary outcome was 24-h area under the curve (AUC) pain score. Pain scores were interpreted in the context of a population-specific minimal clinically important difference of 1.86 cm on a 10-cm visual analogue scale, or an AUC pain score of 5.58 cm.h. Secondary outcomes included analgesic consumption, functional recovery and opioid-related side-effects. In all, 18 trials (1318 patients) were included. Adding QLB to general or spinal anaesthesia improved 24-h AUC rest pain scores by a mean difference (95%CI) of -3.56 cm.h (-6.70 to -0.42; p = 0.034) and - 4.19 cm.h (-7.20 to -1.18; p = 0.014), respectively. These improvements failed to reach the pre-determined minimal clinically important difference, as did the reduction in analgesic consumption. Quadratus lumborum block improved functional recovery for general, but not spinal, anaesthesia. Opioid-related side-effects were reduced with QLB regardless of anaesthetic modality. Low-to-moderate quality evidence suggests that the extent to which adding QLB to either general or spinal anaesthesia reduces postoperative pain and opioid consumption after total hip arthroplasty is statistically significant but may be clinically unimportant for most patients. However, adding QLB to general anaesthesia might enhance functional recovery. Taken together, our findings do not support the routine use of QLB as part of multimodal analgesic regimens for total hip arthroplasty.

[PMID: 35910090 PMCID: PMC9331804 DOI: 10.2147/jpr.s371140] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Accepted: 07/18/2022] [Indexed: 11/29/2022] Open
Abstract
Purpose Local anesthetics can spread into the subendothoracic fascia compartment via the arcuate ligament and apposition zone of the diaphragm after the anterior quadratus lumborum blocks. Therefore, a new block may be achieved if local anesthetic is administered into the diaphragmatic apposition zone (DAZ) under direct laparoscopic visualization by surgeons. Therefore, we evaluated the sensory loss and postoperative analgesic efficacy of this new block in patients receiving laparoscopic nephrectomy. Methods A total of 28 patients scheduled to receive elective laparoscopic nephrectomy under general anesthesia were enrolled in this study. The DAZ blocks were performed in patients under direct laparoscopic visualization with 20 mL of 0.5% ropivacaine before the dissected kidneys or renal tumors were taken out from the incision. All patients received the intravenous patient-controlled analgesia after surgery. The dermatomes of sensory loss and the muscle weakness of quadriceps femoris were assessed at 2 h post-surgery in the wards. The postoperative pain was scored. The opioid consumption in the first 24 h after surgery was recorded. Results The average number of dermatomes of sensory block was 8.6 ± 1.2. The highest level of sensory loss was T6 (T5-T6) [median (interquartile range, IQR)], and the lowest level of sensory block was L1 (L1–L2). The postoperative pain scores at rest or on movement at 2 h, 6 h, 12 h, 24 h and 48 h were kept at the low levels (less than 4). The muscle strength of the quadriceps femoris evaluated was 5 (5–5) points [median (IQR)]. Total dose of intravenous morphine equivalent consumption in the first 24 h after surgery was 21.2 ± 4.1 mg. Conclusion The DAZ block manifests a wide dermatomal coverage of sensory loss and is associated with the low levels of postoperative pain intensity and opioid use. It provides a new postoperative analgesia option for patients undergoing laparoscopic nephrectomy.

Abstract
ABSTRACT
Controlled trials assessing quadratus lumborum block (QLB) for post-operative analgesia in hip surgery are scarce. This study aimed to compare ultrasound-guided QLB and lumbar plexus block (LPB) for clinical efficacy in hip arthroscopy. Patients undergoing hip arthroscopy in Beijing Jishuitan Hospital in January–June 2019 were randomized to the lumbar plexus (L) and quadratus lumborum (Q) groups (n = 25/group). After either ultrasound-guided block for 30 min, both groups were prepared for surgery after muscle strength measurement in the affected limbs. Opioid doses for patient-controlled analgesia (PCA), visual analog scale (VAS) scores in the resting and active states, upon leaving the post-anesthesia care unit (PACU), and at 2–48 h post-surgery were recorded, and post-operative complications were also recorded. Muscle strength in the affected limbs was significantly higher in the Q group compared with the L group (4.0 versus 2.0, P < 0.001). VAS scores were similar in both groups post-surgery (P > 0.05). One patient had epidural spread in the L group, with no other complications. Compared with ultrasound-guided LPB, ultrasound-guided QLB provides similar and good post-operative analgesia after hip arthroscopy, with less impact on muscle strength and fewer complications. These results should be confirmed in larger trials.

Abstract
PURPOSE To examine acute postoperative opioid consumption in patients undergoing hip arthroscopy and randomized to either receive a preoperative lateral quadratus lumborum block or sham injection. METHODS This trial randomized 46 subjects undergoing hip arthroscopy with a single surgeon to receive a preoperative lateral quadratus lumborum block (40 mL, ropivacaine 0.25%) or sham injection. The primary outcome was postoperative opioid consumption in patients with and without a block. All opioid medications were converted to morphine milligram equivalents for comparisons. Categorical data were compared with χ2 tests and Fisher exact tests where appropriate. Continuous data were compared with 2-sided t-test and Wilcoxon rank-sum tests. RESULTS Forty-six subjects scheduled for elective hip arthroscopy were successfully consented and randomized. Demographic and clinical characteristics did not differ. Postoperative opioid consumption decreased 28.3% in patients who received a preoperative lateral quadratus lumborum block (P = .04). Total perioperative opioid consumption (intraoperative and postoperative combined) was reduced 20% in the block group; however, this did not achieve statistical significance (P = .05). Three subjects in the sham group (12.5%) required unblinding for a rescue block in the postoperative anesthetic care unit (PACU) for uncontrolled pain despite systemic analgesics. While cold sensation was decreased postoperatively over the abdomen (P < .001) and anterior thigh (P = .03) in the block group, other PACU variables did not differ, including VAS pain scores, motor function, side effects, PACU duration, and patient satisfaction. CONCLUSIONS Opioid consumption was reduced in patients who received a preoperative lateral quadratus lumborum block combined with a standardized, multimodal protocol as compared with patients who did not receive a block. Our findings support the growing evidence that quadratus lumborum blocks are an effective component of multimodal analgesia options for patients undergoing elective hip arthroscopy. LEVEL OF EVIDENCE Level I, randomized controlled trial.

Abstract
Background Hepatic resection is a major abdominal surgery with challenging pain management. We aimed to investigate the effect of erector spinae plane block (ESPB) with opioid free anesthesia (OFA) in cirrhotic patients scheduled for liver resection on perioperative pain management in terms of hemodynamic stability. Secondarily, we assessed time to first request for analgesia and perioperative fentanyl consumption, nausea and vomiting within 24 hours after surgery. Methods Forty patients were randomized to block group (n = 20): OFA with ESPB and conventional group (n = 20): conventional balanced anesthesia with opioids (OFA associated non-opioid drugs [dexmedetomidine, magnesium sulfate, xylocaine, and acetaminophen] and ESPB). Bilateral ESP block was done with ultrasound guidance at the level of thoracic vertebrae T 6–7, the local anesthetic dose was 20 mL Bupivacaine 0.25% with adjuvant dexmedetomidine (0.5 µg/kg) on each side. We monitored hemodynamic stability as the primary endpoint (heart rate, mean arterial blood pressure, and cardiac output). Results Bilateral ESPB offered somatic and visceral analgesia for hepatic resection patients with no intraoperative fentanyl required. Postoperatively, the block group with dexmedetomidine adjuvant to the local anesthesia drugs showed delay in the first request for analgesia (p = 0.092) and decreased fentanyl requirement (p < 0.001), so no patient in the ESP group suffered from postoperative nausea and vomiting compared to 50% in the conventional group (p < 0.001). Conclusion Bilateral ESP block with OFA is an effective approach for intra- and postoperative analgesia in cirrhotic patients undergoing liver resection.

Abstract
BACKGROUND Prostatic hyperplasia is a physiological aging process in men. After transurethral resection of prostate (TURP), visceral pain is the main cause. The effective postoperative analgesia can reduce the occurrence of postoperative complications. This study mainly studied the analgesic effect of quadratus lumborum block (QLB) on TURP. METHODS We divided 62 patients undergoing TURP into 2 groups using a random number table method (QLB 2 group and non-QLB [control] group). Patients in the QLB group underwent ultrasound-guided posterior QLB with 20 mL of 0.25% ropivacaine on each side, and those in the control group received only general anesthesia. The primary outcome for this study was the consumption analgesic pump during 0 to 24 hours. The secondary outcomes included the first pressing time of analgesic pump during 0 to 24 hours, the pain at rest and when coughing at 1, 4, 8, 12, and 24 hours post-operation as measured with a visual analogue scale for pain, length of the hospital stay, and complications (nausea and vomiting, dizziness, and abdominal distension). RESULTS Patients in the QLB group presented less consumption, later first pressing time of analgesic pump during 0 to 24 hours after surgery lower visual analogue scale scores at 1, 4, 8, 12, and 24 hours postsurgery than those in the control group. Moreover, their mean length of hospital stay was shorter (P = .023), and they experienced less postoperative complications than the patients in the control group. CONCLUSIONS Ultrasound-guided QLB in TURP provided a significant analgesic effect in our patients the first day after surgery. This analgesic model may improve the postoperative recovery after TURP.

Abstract
Introduction Ultrasound (US) guided transmuscular quadratus lumborum block (TMQLB) has been widely used as regional anaesthesia (RA) technique for managing postoperative pain after intraperitoneal and retroperitoneal procedures like nephrectomy, percutaneous nephrostomy, cholecystectomy, and also for hip surgeries. Although continuous epidural analgesia is considered the gold standard for most of these procedures, alternative techniques such as transversus abdominis plane (TAP) block and continuous rectus sheath block have also been used successfully. US-guided TMQLB seems to have more advantages than TAP block as it blocks the visceral afferents. With more cephalad spread of the local anaesthetic into the thoracic paravertebral space, it might block somatic pain from T6 to L2 as well. Methods After institutional ethics committee approval, we recruited 64 consecutive patients in the study and randomized them into two groups. Patients in the study group received bupivacaine (0.125%) and the control group received normal saline as a continuous infusion for 48 hours. Both groups were compared for 48 hours morphine consumption, time to first analgesic, hemodynamics, postoperative nausea/vomiting (PONV), sedation, and other adverse events. Results Data from 60 patients were analyzed. Forty-eight hours of morphine consumption in group A (study) was less than group B (7.4 ± 4.57 mg versus 11.86 ± 5.58 mg) and the time to first morphine requirement was 240 min (105-500) in group A compared to 90 min (90-225) in group B which was statistically significant. Demographic data, American Society of Anesthesiologists physical status, hemodynamics, Ramsay sedation score (RSS), and PONV were comparable in both groups. Conclusion Continuous US-guided TMQLB appears to be a safe and effective RA technique for managing postoperative pain after nephrectomy for up to 48 hours.

Abstract
Background To investigate the role of transmuscular quadratus lumborum block (TMQLB) for postoperative pain control, patient satisfaction and recovery in laparoscopic adrenalectomy. Methods
Seventy-two patients aged between 18 and 70 years with an ASA I-II and scheduled for laparoscopic adrenalectomy were randomized to receive a single-shot TMQLB with 0.4 ml/kg 0.5 % ropivacaine or 0.4 ml/kg 0.9 % saline as placebo. The primary endpoint was pain on movement at 12 h after surgery evaluated by the numeric rating scale (NRS, 0–10). P-values < 0.05 was considered statistically significant. The secondary outcomes included pain at rest and pain on movement evaluated by the NRS, and postoperative recovery related parameters. Results NRS on movement at 12 h after surgery was lower in the TMQLB group compared with the control (median 2 vs. 3, p = 0.024). Intraoperative fentanyl consumption was lower in the TMQLB group (247.08 ± 63.54 vs. 285.44 ± 74.70, p = 0.022). The rate of using postoperative rescue tramadol was also lower in the TMQLB group (5.6 vs. 27.8 %, p = 0.027). Similar incidences of nausea and vomiting were observed (11.1 vs. 25 %, p = 0.220). Patient satisfaction of pain service was better in the TMQLB group (83.3 vs. 25 %, p < 0.001) with shorter time to ambulation (16.5 vs. 21 h, p = 0.004) and flatus (18.5 vs. 23.5 h, p = 0.006). Conclusions TMQLB showed better control of postoperative pain on movement for laparoscopic adrenalectomy with improved patients’ satisfaction of anesthesia, shorter time to ambulation and flatus. Trial registration This study was registered at Clinicaltrials.gov (NCT03942237; registration date: 08/05/2019; enrollment date: 10/05/2019).

Abstract
Simple Summary This study describes a modified approach for the ultrasound-guided quadratus lumborum block in dogs. Previous studies carried out in canine cadavers describe the needle insertion following a ventro-lateral to dorso-medial approach. Our modified technique follows a dorso-lateral to ventro-medial direction. We aimed to have the same success with this approach as previous studies in dogs but to minimise the potential complications. After performing the modified technique bilaterally in nine canine cadavers and administering contrast, we assessed the contrast distribution with computed tomography (CT) and dissection. Potential complications were also assessed. Our dissection results showed similar distribution to previous studies, although CT results showed a more caudal contrast spreading. No contrast was found in the abdomen or epidural space. This study shows that our modified approach is safe and has at least the same distribution as the previous studies published in dogs. Abstract Ultrasound-guided quadratus lumborum block (QLB) is a locoregional technique described in canine cadavers. The aim of this study was to assess a modified approach to QLB to minimise potential complications such as abdominal organ puncture. Nine canine cadavers were included and were positioned in lateral recumbency. An ultrasound-guided QLB was performed on each side. The probe was placed in the transverse position over the lumbar muscles just caudal to the last rib, and a needle was advanced in-plane from a dorso-lateral to a ventro-medial. A volume of 0.2 mL kg−1 of a mixture of iomeprol and methylene blue was injected. Computed tomography (CT) and dissection were performed to evaluate the spreading. Success was defined as staining of the nerve with a length of more than 0.6 cm. Potential complications such as intra-abdominal, epidural, or intravascular spreading of the mixture were also assessed. The CT images showed a T13 to L7 vertebra distribution, with a median of 5 (3–6). Dissection showed staining of the nerves from T13 to L4, with a median of 3 (2–5). No complications were found. This modified approach to QLB is safe and shows similar results to the previous studies in canine carcass.

Abstract
BACKGROUND An effective analgesia strategy following caesarean delivery should be designed to improve fetomaternal outcomes. Much recent research has focused on the efficacy of ilioinguinal-iliohypogastric (II-IH) block for providing such analgesia. DESIGN A systematic review and meta-analysis of randomised controlled trials. OBJECTIVES To investigate the effectiveness of II-IH block in patients undergoing caesarean delivery. The primary outcome was the cumulative parenteral morphine equivalents at 24 h. Pain scores at 4 to 6 and 24 h postsurgery, time to first rescue analgesia and adverse effects were the secondary outcomes analysed. DATA SOURCES Two reviewers searched independently PubMed, Embase, Google Scholar and the Cochrane central registers of a controlled trial from their inception until June 2020. METHODOLOGY Prospective randomised control trials comparing II-IH block with either systemic analgesia alone or a placebo block (non-active controls) were eligible for inclusion. Only trials that reported their methods comprehensibly and transparently were included. Cochrane methodology was used to assess the risk of bias. Data are presented as mean difference with 95% confidence interval (CI). RESULTS Thirteen trials comprising a total of 858 patients were included. Opioid (intravenous morphine equivalents) consumption was reduced by 15.57 mg (95% CI -19.87 to -11.28; P < 0.00001; I2 = 95%) during the first 24 h in patients receiving II-IH block when compared with placebo or no block. Patients receiving general anaesthesia showed a greater reduction in morphine requirement at 24 h than those receiving neuraxial anaesthesia. Adequate 'information size' for the above outcome was confirmed with trial sequential analysis to rule out the possibility of a false-positive result. II-IH also significantly reduced pain scores at rest more so at 4 to 6 h than at 24 h. CONCLUSIONS Our study suggests that the use of II-IH blocks is associated with a lower 24 h requirement for intravenous morphine equivalents in patients undergoing caesarean delivery. However, given the methodological limitations, data should be interpreted with caution until more studies are available.

Abstract
The erector spinae plane block (ESPB) has recently been described as an effective analgesic strategy for various surgeries at ventral and dorsal parts of body. The block has been utilized for postoperative pain relief in hip surgeries. Cadaveric and clinical studies performed at the lumbar level depict a dorsal spread and minimal ventral spread in the lumbar plexus. So far to our knowledge there is one case report which has described reduced quadriceps strength in a parturient after caesarean section. We report two patients who presented with absent knee reflexes (decreased quadriceps strength) and one patient with absent ankle reflex (foot drop) following continuous ESPB at the level of L3. The initial bolus was with 30 ml of 0.1% bupivacaine followed by a continuous infusion of 0.1% ropivacaine at 8ml/hour. The loss of knee reflexes in two patients and diminished reflexes in one patient suggested spread of local anaesthetic (LA) to the lumbosacral plexus. The LA infusion were stopped in all 3 patients. The average duration of motor block was 18 hours. These complications should be considered if early ambulation is mandatory for patients.

Abstract
The subcostal quadratus lumborum (QL) block is used in postoperative analgesia for abdominal surgery. However, only a small portion of local anesthetic can spread into the thoracic paravertebral space from the injection site via the lateral arcuate ligament, due to the barrier action of the ligament. In this study, we determined the effectiveness of a new ultrasound-guided parasagittal approach to anterior QL block at the lateral supra-arcuate ligament. Twenty six patients scheduled for laparoscopic renal surgery were enrolled. The parasagittal approach to the anterior QL block at the lateral supra-arcuate ligament was carried out preoperatively. Our data showed that at 5 and 10 min after injection, the patients achieved the sensory block of dermatomes T9-T12 and T7-L1, respectively. Some patients achieved coverage as cephalad as T5 and as caudal as L3. Four patients (16.7%) developed quadriceps weakness after the blocks. The parasagittal technique provides a new choice for postoperative analgesia of abdominal surgery with rapid onset and reliable dermatomal coverage.Trial registration: Chinese Clinical Trial Registry: ChiCTR2000029211.

Abstract
BACKGROUND Ultrasound-guided quadratus lumborum block (QLB) is a truncal block with several technique variations. It has been reported as providing effective analgesia for postoperative pain. OBJECTIVES The aim of this review was to evaluate the efficacy and safety of QLB for postoperative analgesia. The primary outcome was cumulative opioid consumption at 24 h postoperatively. The main secondary outcomes were the time to the first rescue opioid analgesic, pain scores at 24 h postoperatively and the incidence of postoperative nausea and vomiting (PONV). DESIGN This was a systematic review and meta-analyses of observational studies and randomised controlled trials (RCTs). PRISMA-P guidelines were followed, and the review was registered in PROSPERO. GRADE was used to assess the quality of evidence. DATA SOURCES The search was performed from several databases (Ovid MEDLINE, PubMed, Scopus, Web of Science, CINAHL and the Cochrane CENTRAL) from inception up to June 2019. ELIGIBILITY CRITERIA RCTs and prospective observational studies that investigated the postoperative analgesic properties of US-guided single shot QLB in adult patients undergoing abdominal or hip surgery were included. QLB was compared with other analgesics. RESULTS Twenty-seven studies constituting 1557 patients were reviewed. Twelve studies with 803 patients were included in the meta-analysis on the primary outcome. Overall opioid consumption at 24 h postoperatively was reduced [mean difference, -11.15 (95% CI, -15.33 to -6.97) mg, I2 = 99%, moderate certainty in GRADE] and the time to the first opioid analgesic was longer in patients with QLB: 7 studies with 499 patients, mean difference, 189.32 (95% CI, 114.4 to 264.23) min, I2 = 98%. There were no differences in pain grades. The incidence of PONV was lower in patients with QLB [11 studies with 744 patients, OR 0.40 (95% CI, 0.27 to 0.58), I2 = 7%]. Reported complications and adverse effects of QLB were minimal. CONCLUSION QLB reduced postoperative opioid consumption, prolonged the time to the first rescue opioid analgesic and diminished the incidence of PONV. QLB appears to be an applicable option for postoperative analgesia after abdominal and hip surgery. REGISTRATION NUMBER PROSPERO, https://www.crd.york.ac.uk/prospero/, CRD42016039921.

Abstract
Purpose To evaluate the effect of the single-shot quadratus lumborum (QL) block versus femoral nerve and fascia iliacus (F/FI) blocks performed preoperatively on perioperative opioid requirements, subjective pain scores, and time to discharge. Methods Patients who underwent hip arthroscopy for femoroacetabular impingement and had a preoperative nerve block between January 2017 and August 2019 at our institution were identified. Patients were separated into 2 groups: those who either received a preoperative single-shot QL block or a preoperative single-shot F/FI block. All patients received general anesthesia. Intraoperative, postanesthesia care unit (PACU), and total morphine equivalents were analyzed using unpaired t test. Secondary outcome measures including total time in PACU and block-related complications were recorded and analyzed as well. Results One hundred one patients were retrospectively reviewed. Forty-three patients received preoperative QL blocks, and 58 patients received preoperative F/FI blocks. Demographics and operative characteristics were similar between the 2 groups. Patients receiving a QL block required significantly lower total morphine equivalents (63.1 vs 87.0, P < .001). Patients receiving a QL block also had shorter PACU stays (116 vs 148 minutes, P < .001) and lower subjective pain scores at the time of discharge (3.27 vs 4.98, P < .001) compared with the F/FI block group. There were also significant decreases in the number of intraoperative opioids (42.1 vs 58.4, P < .001) and PACU opioids (20.7 vs 28.7, P = .03) used when analyzed separately. Two patients in the femoral nerve block group had noted a fall postoperatively while the block was in effect. No patients in the QL block group had a block-related complication. Conclusions Patients receiving a preoperative QL block for hip arthroscopy demonstrated lower total opioid requirements, shorter PACU stay, and lower pain scores at discharge than patients receiving preoperative F/FI blocks with no reported adverse events. Level of Evidence Level III, retrospective comparative trial.

Abstract
Orthopedic procedures involving the hip have remained challenging for regional anesthesia given the complex innervation, painful nature contributing to difficulty positioning, and a desire to maintain mobility to hasten postoperative recovery. The revision total hip arthroplasty (THA) poses a greater challenge for an effective regional analgesia due to complex surgical approach, scarring from previous surgery and limited patient mobility. The quadratus lumborum (QL) block has demonstrated to provide effective analgesia for primary hip surgery in recent studies. The pericapsular nerve group (PENG) block has also shown to provide analgesia in patients with hip fractures. There is no standard of care regional anesthesia technique for hip surgeries, and the regional practice varies widely among anesthesia providers. This retrospective case series studied the effect of combining the QL with PENG block on the revision THA analgesia.

Abstract
BACKGROUND The interest in and demand for post-bariatric surgery have increased along with the increase in obesity surgery. Belt lipectomy, during which a circular correction is made in the center of the trunk, is the most commonly performed among these surgical techniques. Postoperative pain is an important problem due to the size of the surgical site and stretched closure. In this study, it was aimed to evaluate the intraoperative and postoperative narcotic analgesic consumption, postoperative analgesic requirement, postoperative visual analog scale (VAS) scores, postoperative nausea and vomiting (PONV), and the first mobilization time in patients with and without erector spinae plane block (ESPB). METHODS The files of patients who had undergone belt lipectomy between 2016 and 2019 in our hospital were retrospectively reviewed. Patients who received ESPB were called group 1, and those who did not undergo ESPB were called group 2. Their demographic characteristics, intraoperative and postoperative narcotic and non-narcotic analgesic consumption, VAS scores, PONV, and the first mobilization times were recorded. RESULTS The files of a total of 51 patients, including 23 patients in group 1 and 28 patients in group 2, were reviewed. It was determined that intraoperative and postoperative narcotic analgesic consumption (p < 0.005), PONV (p < 0.005), and the first mobilization time (p < 0.005) were significantly lower in group 1 compared with group 2. CONCLUSION The use of the ESP block in belt lipectomy surgeries significantly reduces intraoperative and postoperative narcotic analgesic consumption and pain scores.

Abstract
Background: Quadratus lumborum block (QLB) has provided adequate analgesia and lowered postoperative opioid requirement in comparison to controls for some urological surgeries. Aims: The aim of this study was to assess the efficacy of postprocedure ultrasound-guided QLB in comparison to port-site infiltrations with local anesthetics (as control) in lowering postoperative pain after laparoscopic pyeloplasty. Settings and Design: This was a prospective, single-blinded, randomized controlled trial. Materials and Methods: Fifty-three adults undergoing laparoscopic pyeloplasty were randomly allocated to either anterior QLB group (n = 27) or port-site infiltration Group P (n = 26) with 20 mL of 0.5% ropivacaine. The primary outcomes were static and dynamic pain on the Visual Analog Scale (VAS) of 0–100 at the 30th min, 2nd, 6th, 12th, and 24th hour after surgery. The secondary outcomes were number of patients requiring rescue analgesics and having postoperative nausea or vomiting (PONV) in 24 hours after surgery. Statistical Analysis: Intergroup comparison of VAS was done with Student's t-test. Categorical data were analyzed using the Chi-square test. Results: The static VAS scores were found to be significantly lower in QLB group at the 2nd, 6th, and 12th hour, and the dynamic VAS was lower at all time points after the 30th min in the QLB group. The number of patients requiring rescue analgesics were significantly lower in the QLB group (13 as compared to 21 in Group P; P = 0.015). The incidence of PONV was comparable. No other side effects were seen. Conclusion: Ultrasound-guided anterior QLB is more effective in comparison to traditional technique of port-site local anesthetic infiltration for providing analgesia after laparoscopic pyeloplasty.

Abstract
Background and Aims: This study aims to evaluate the analgesic effect of ultrasound-guided erector spinae plane block (ESPB) in paediatric lower abdominal surgeries. Methods: Randomised, prospective trial. Forty patients, aged 2–10 years with the American Society of Anesthesiologists Score of I and II scheduled for elective lower abdominal surgery were included in the study. Interventions: Patients were randomised into two groups as control group and ESPB group. Ultrasound-guided erector spinae plane block at L1 vertebral level was performed preoperatively using 0.5 ml/kg 0.25% bupivacaine (max 20 ml) for the patients in ESPB group. Analgesic requirements and time to first analgesic requirement were recorded and Face, Legs, Activity, Cry and Consolability (FLACC) scores for pain were recorded at 0, 1, 2, 3, 6, 12 and 24 h postoperatively. Results: Forty patients were included in the final analyses. Significant difference was determined between the groups on post-operative morphine requirement and FLACC scores at 3 h and 6 h postoperatively (P < 0.05). Significant difference was also determined in time to first dose of rescue analgesia between the groups (P < 0.05). Conclusions: This study shows that the ESPB provides adequate post-operative analgesia in paediatric patients undergoing lower abdominal surgery.

Abstract
Background and Aims Postoperative pain following renal transplantation is moderate to severe. Quadratus lumborum block (QLB) is a new block that can provide effective analgesia following abdominal and retroperitoneal surgeries. This study aimed to evaluate the analgesic efficacy of QLB for postoperative analgesia in patients undergoing renal transplantation. Methods Patients were randomised into two groups of 30 each. In group A (block group), 20 mL of 0.25% bupivacaine and group B (placebo group), 20 mLof normal saline were injected. In the postoperative room, an intravenous patient controlled analgesia (IVPCA) pump with fentanyl was started in both the group. The postoperatively recorded parameters were numerical rating scale (NRS) pain score at rest and on movement and coughing, total fentanyl consumption, sedation score, postoperative nausea vomiting, limb weakness, paralytic ileus, and any other block-related complication. Data were analysed using SPSS software version 22.0. Categorical data were analysed using the Chi-square method. Student t test or Mann-Whitney U test was applied for the continuous data. Numerical data with normal distribution were displayed as mean (standard deviation), abnormal distribution was displayed in the median (interquartile range) values, and as a percentage for categorical variables. Results Fentanyl consumption, numerical rating score, and sedation score were significantly less in group A when compared to group B at 1, 4, 8, 12, and 24 h (P < 0.001). Conclusion Type-1 QLB significantly reduces fentanyl consumption and NRS pain score at 1,4,8,12, and 24 h in the postoperative period in renal transplant recipients.

Abstract
OBJECTIVE To describe an ultrasound-guided lateral quadratus lumborum (LQL) block technique and the spread characteristics of lidocaine-dye injected in the LQL plane using a transversal (LQL-T) or a longitudinal (LQL-L) approach. STUDY DESIGN Experimental anatomic study. ANIMALS A total of eight canine cadavers. METHODS Bilateral ultrasound-guided injections in the fascial plane lateral to the quadratus lumborum muscle and medial to the thoracolumbar fascia (LQL plane) with the needle directed at the first lumbar (L1) transverse process were performed using lidocaine-dye (0.3 mL kg-1). Anatomical dissection determined the dye distribution, sympathetic trunk staining and number of spinal nerves stained circumferentially >1 cm. RESULTS The LQL fascial plane was ultrasonographically recognized in all cadavers and filled with lidocaine-dye in all eight cadavers with the LQL-T approach and in six with LQL-L. The injectate spread ventral to the lumbar transverse processes, around the quadratus lumborum muscle and dorsal to the transversalis fascia, affecting the ventral branches of the spinal nerves and the sympathetic trunk. A median (range) of 4 (3-5) and 3 (0-4) ventral branches of the thoracolumbar nerves were dyed with LQL-T and LQL-L approaches, respectively (p = 0.04). The most cranial nerve stained was the twelfth thoracic (T12) with the LQL-T approach and T13 with LQL-L, and the most caudal was L3 with both approaches. The incidence of sympathetic trunk staining was significantly higher using LQL-T (six injections) compared with LQL-L (one injection; p = 0.04). Dye was not observed in the lumbar plexus, epidural space or abdominal cavity. CONCLUSIONS AND CLINICAL RELEVANCE Ultrasound-guided LQL-T approach resulted in a more consistent spread toward the spinal nerves and sympathetic trunk compared with LQL-L approach. Further studies are necessary to assess the LQL block effectiveness and success rate in live dogs.

Abstract
Ultrasound-guided quadratus lumborum (QL, QL1-3) blocks have been used extensively for perioperative pain control for patients undergoing abdominal procedures. These blocks provide a more widespread and longer-lasting analgesic effect compared to the transversus abdominis plane (TAP) block. While QL blocks have been used as an adjunct in multimodal postoperative pain control, they are rarely used as the sole anesthetic technique for abdominal surgeries. We report the cases of two high-risk multimorbid patients requiring urgent open umbilical hernia repairs secondary to incarceration or obstruction. Bilateral QL2 blocks were utilized as the sole anesthetic technique to reduce anesthetic risk, with positive outcomes. Utilization of the QL2 block technique for our patients enabled avoidance of general anesthesia in these high-risk patients because of the extensive area of anesthesia they provide when compared with the TAP and QL1 block techniques. The advantages of the QL2 block for high-risk patients include immediate perioperative pain control, reduced use of muscle relaxants, reduced opioid analgesic requirement for postoperative pain management, and enhanced postoperative recovery. Disadvantages include potential for local anesthetic toxicity, neural injury, or failure of the block. While regional anesthetic techniques may be beneficial options for those patients who are not candidates for general anesthesia, more studies in which these techniques are used need to be performed to determine the widespread efficacy and adequacy of this method.

J Anesth 2020; 34:814-824.

Abstract
PURPOSE Quadratus lumborum block (QLB) has recently gained popularity for postoperative analgesia after cesarean delivery (CD) as it provides both visceral and somato-sensory blockade of the abdomen. Aim of this meta-analysis was to evaluate the analgesic potential of QLB after CD. METHODS Electronic database from inception to December 2019 was searched systematically for randomized-controlled trials comparing QLB with injection of inactive solution in women undergoing CD. Primary outcome was consumption of morphine at 24 h. Morphine consumption at 48 h, dynamic and static pain scores at various time intervals were the secondary outcomes studied. RESULTS Seven trials met the inclusion criteria. Morphine consumption was reduced significantly with QLB in comparison to sham or no block at 24 h (mean difference [MD] - 9.84 mg; 95% confidence interval [CI] - 18.16, - 0.50; p = 0.04; I2 = zero). Adequate "information size" for above outcome was confirmed with trial sequential analysis, ruling out any possibility of a false-positive result. QLB significantly reduced pain scores at rest (MD - 1.13; 95% CI - 1.75, - 0.56; p = 0.00) and on movement (MD - 1.48; 95% CI - 2.5, - 0.46; p = 0.01) at 6 h. However, statistically significant difference in pain scores persisted only for dynamic pain at 24 h (MD - 0.55; 95% CI - 1.04, - 0.06; p = 0.03). QLB does not provide any additional analgesic benefit to the parturient receiving intrathecal morphine. CONCLUSION QLB significantly reduces opioid requirements in CD and may have analgesic effects lasting 24 h.

Abstract
Background and Aims Liposomal bupivacaine (LB) is a formulation of local anesthetic that may exert analgesia over a prolonged period. Anecdotal use of LB suggests benefit and prolonged analgesia when used to supplement infiltration blocks. Our aim was to test the effect of a bolus of LB delivered through a nerve catheter in two types of interfascial plane blocks (transversus abdominis plane and anterior subcostal quadratus lumborum). The effect was evaluated through patient self-reporting of postsurgical pain up to 48 postoperative hours. Material and Methods Medical records of adult postoperative patients who received LB in a peripheral nerve catheter were followed retrospectively and analysed for pain scores and spread of dermatomal numbness over 48 h following the postoperative dose. A chart review of patients who qualified between June 2015 and March 2017 was performed, and clinical data were obtained from the institutional Perioperative Health Documentation System. Results Pain scores decreased following LB bolus, and all patients reported efficient block analgesia after bolus injection. Dermatomal numbness decreased gradually and was minimal by 48 h following bolus. Conclusion LB can be injected through a peripheral nerve catheter to prolong analgesia after catheter removal.

Ultrasound-Guided Transmuscular Quadratus Lumborum Block Reduces Postoperative Pain Intensity in Patients Undergoing Total Hip Arthroplasty: A Randomized, Double-Blind, Placebo-Controlled Trial. Pain Res Manag 2020; 2020:1035182. [PMID: 32256907 PMCID: PMC7085398 DOI: 10.1155/2020/1035182] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2019] [Revised: 02/03/2020] [Accepted: 02/13/2020] [Indexed: 11/18/2022]
Abstract
Methods Eighty-eight patients undergoing THA were randomized to receive 0.33% ropivacaine (Group QLB, n = 44) or saline (Group Con, n = 44) for QL3 block. Spinal anesthesia was then performed. Pain intensity was assessed using the visual analog scale (0: no pain to 10: worst possible pain). The primary outcome was pain scores recorded at rest at 3, 6, 12, 24, 36, and 48 h and on standing and walking at 24, 36, and 48 h postoperatively. Secondary outcomes were analgesic consumption, side effects, the 10-meter walking speed on day 6, and patient satisfaction after surgery. Results Postoperative pain intensity was significantly lower in Group QLB compared to Group Con at rest after 3, 6, 12, 24, 36, and 48 h (p < 0.001) and during mobilization after 24, 36, and 48 h (p < 0.001). Morphine use was significantly lower in Group QLB compared to Group Con during 0–24 h (16.0 ± 7.1 vs. 34.1 ± 7.1 mg, p < 0.001) and during 24–48 h (13.0 ± 4.0 vs. 17.4 ± 4.6 mg, p < 0.001) postoperatively. The 10-meter walking speed was higher in Group QLB compared to Group Con, both at comfortable (0.79 ± 0.13 vs. 0.70 ± 0.14 m/s, p=0.012) and at maximum speeds (1.18 ± 0.26 vs. 1.06 ± 0.22 m/s, p < 0.001). Incidences of nausea (7.3% vs. 31%, p=0.006), vomiting (7.3% vs. 26.2%, p = 0.022), and urinary retention (9.8% vs. 28.6%, p=0.030) were lower in Group QLB than in Group Con. Conclusions Ultrasound-guided QL3 block is an effective pain management technique after THA.
