Ultrasound-Guided Quadratus Lumborum Block Versus Caudal Block for Pain Relief in Children Undergoing Lower Abdominal Surgeries: A Randomized, Double-Blind Comparative Study.

ABSTRACT:

Background

The quadratus lumborum (QL) block, also known as the abdominal truncal block, was developed to provide visceral and somatic analgesia during abdominal procedures.

Objectives

This study aimed to assess pain alleviation, the incidence of complications in lower abdominal procedures, and hemodynamic stability between the caudal block and ultrasound-guided QL block.

Methods

Fifty-two patients aged 1 to 7 years old from both genders scheduled for unilateral lower abdominal surgery were randomly assigned to 2 study groups: group QL, unilateral QL block (n = 26), and group C, caudal block (n = 26). In group C, children received caudal block. In group QL, an ultrasound-guided QL block was performed. The time to first rescue analgesia was evaluated as a primary outcome. The quality of analgesia was determined using the face, legs, activity, cry, consolability scale (FLACC scale), hemodynamic parameters, and incidence of complications because hemodynamic instability was recorded under ultrasound guidance. Signs of local anesthetics toxicity and the parents' satisfaction were secondary outcomes.

Results

The time until the first demand for analgesia postoperatively was statistically longer in group QL compared to group C. A non-significant difference was observed between the 2 groups (P > 0.05) regarding age, weight, gender, duration of surgery, type of surgery, FLACC scale, and hemodynamics (SBP, systolic blood pressure), except at 30 minutes, which was significant in QL block. Also, a non-significant difference was observed in the severity of postoperative pain up to 1 day postoperatively. Group QL showed more satisfaction than group C. No intraoperative complications were detected.

Conclusions

Compared to caudal block, QL block produced sustained and adequate analgesia time postoperatively, with higher satisfaction.

Project description:BackgroundSeveral studies have reported the use of anterior, posterior and lateral quadratus lumborum block (QLB) for pain control in hip surgeries. However, high-quality evidence is lacking. The current review aimed to summarize data on the efficacy of QLB for pain control in patients undergoing hip surgeries.MethodsPubMed, Embase, and Google Scholar databases were searched up to August 5, 2021 for randomized controlled trials (RCTs) or non-RCTs assessing the efficacy of QLB for any type of hip surgery.ResultsThirteen studies were included (nine RCTs and four non-RCTs). On pooled analysis, there was a statistically significant reduction of 24-h total opioid consumption in patients receiving QLB as compared to the control group (MD: -9.92, 95% CI: -16.35, -3.48 I 2 = 99% p = 0.003). We noted a statistically significant reduction of pain scores in the QLB group as compared to control group at 2-4 h (MD: -0.57, 95% CI: -0.98, -0.17 I 2 = 61% p = 0.005), 6-8 h (MD: -1.45, 95% CI: -2.09, -0.81 I 2 = 86% p < 0.00001), 12 h (MD: -1.12, 95% CI: -1.89, -0.34 I 2 = 93% p = 0.005), 24 h (MD: -0.71, 95% CI: -1.27, -0.15 I 2 = 89% p = 0.01) and 48 h (MD: -0.76, 95% CI: -1.37, -0.16 I 2 = 85% p = 0.01) after the procedure. There was a statistically significant reduction in the risk of nausea/vomiting (RR: 0.40, 95% CI: 0.18, 0.88 I 2 = 62% p = 0.02) in patients receiving QLB but no difference in the risk of pruritis (RR: 0.46, 95% CI: 0.17, 1.24 I 2 = 16% p = 0.13) and urinary retention (RR: 0.44, 95% CI: 0.19, 1.02 I 2 = 0% p = 0.06).ConclusionQLB as a part of a multimodal analgesic regimen reduces opioid consumption and pain scores in patients undergoing hip surgeries. The certainty of evidence based on GRADE was moderate. Despite the statistically significant results, the clinical relevance of the analgesic efficacy of QLB is debatable due to the small effect size.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, identifier: CRD42021267861.

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:BackgroundThe 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).MethodsThe 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.ResultsThe 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.ConclusionsQLB-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.
