“…Surgical treatment is mainly used in clinic at the present stage [ 9 , 10 ]. In order to relieve the pain of patients during and after surgery, general anesthesia combined with QLB block or TAPB block is performed during and after surgery, which has a significant effect on relieving the pain of patients [ 11 , 12 ]. The mechanism of TAPB is to inject local anesthetic into the nerve fascia layer between the internal oblique muscle and transverse abdominis muscle to block relevant nerve sensory conduction so as to weaken the pain sensation in the skin, muscle, and parietal peritoneum of the anterior abdomen and achieve good abdominal analgesia [ 13 , 14 ].…”

Colorectal cancer is a common malignant tumor of the digestive system. In order to study the clinical efficacy of ultrasound-guided QLB and TAPB in the treatment and postoperative analgesia of patients undergoing laparoscopic colorectal surgery. A total of 96 patients undergoing laparoscopic colorectal surgery from January 2021 to January 2022 are selected as the study subjects. The results show that ultrasound-guided QLB and TAPB therapy have good analgesic effects in patients undergoing laparoscopic colorectal surgery, and QLB treatment and postoperative analgesic effect are better than TAPB.

“…Kang et al demonstrated that the analgesia provided by QLB-II and QLB-III was comparable, and that the combination of QLB II and III is superior to either of the approaches alone (29) . Koksal et al demonstrated that QLB-III is superior to QLB-II (30) .…”

Background: Quadratus lumborum block (QLB) was introduced to provide postoperative analgesia. Objective: This randomized controlled, double-blind study aimed to evaluate bilateral posterior QLB for analgesia after cesarean section (CS) using spinal anesthesia without intrathecal morphine. Methods: One hundred ASA-II women with singleton, full-term pregnancy undergoing CS using spinal anesthesia were randomized into 2 groups (Quadratus Lumborum and Control; 50 subjects each). After completing CS, bilateral posterior QLB (20 mL bupivacaine 0.25% on each side) was performed in Quadratus Lumborum group, and bilateral sham procedure was performed in Control group. Results: The median (range) of pain score at rest at 6 h was 2 (1-6) in Quadratus Lumborum group and 5 (2-8) in Control group; median difference (95% CI) was -3 (-3.000007 to -2.99995); P <0.00001. Pain score at rest at 12 h and pain scores on movement at 6 and 12 h were lower in Quadratus Lumborum group. No significant differences in pain scores at rest and pain scores on movement at 24 h were detected between the groups. The number of subjects requesting morphine was smaller, time to the first request of morphine was longer, and total morphine dose was smaller in Quadratus Lumborum group. Patient satisfaction was greater in Quadratus Lumborum group. No significant differences in the incidence of pruritus and nausea/vomiting were detected between the groups. Conclusions: QLB provides adequate postoperative analgesia after CS using spinal anesthesia without intrathecal morphine.

“…One small-sample-size study reported that the analgesic effect of QLB3 was a superior to that of QLB2 in cesarean delivery. 29 However, Brixel, et al 30 recently reported that 30 mL of the QLB2 solution could reach multiple locations around the quadratus lumborum muscle when sonographic localization was used. Therefore, future studies should consider investigating the effects of the different approaches of QLB using varying dosages of the local anesthetic.…”

Objective The quadratus lumborum block provides postoperative analgesia for patients undergoing abdominal surgery, although there are three common approaches to perform this block. The present meta-analysis investigated the effectiveness of posterior quadratus lumborum block (QLB2) after surgery. Methods PubMed, Embase, and the Cochrane Central Register were searched from inception to 26 August 2021 for randomized controlled trials that evaluated the analgesic efficacy of QLB2 vs control (placebo or no block). The primary outcomes were pain scores at 6 h, 12 h, and 24 h after surgery. The secondary outcomes were morphine consumption at 24 h after surgery and the postoperative complications. Results The present meta-analysis included 14 studies conducted with a total of 1001 patients. In comparison to control group, the QLB2 group presented significantly lower rest pain scores at 6 h (SMD −0.59; 95% CI: −1.05, −0.12; p = 0.01, I 2 = 84%; GRADE = moderate), 12 h (SMD: –0.83; 95% CI: –1.47, –0.19; p = 0.01; I 2 = 88%; GRADE = low), and 24 h (SMD: –0.37; 95% CI: –0.71, –0.03; p = 0.03; I 2 = 80%; GRADE = moderate) after surgery. The dynamic pain scores were significantly reduced, compared to control, in the QLB2 group at 12 h (SMD: –0.93; 95% CI: –1.52, –0.33; p = 0.002; I 2 = 83%; GRADE = low) and 24 h (SMD: –0.52; 95% CI: –0.93, –0.11; p = 0.01; I 2 = 83%; GRADE = moderate) after surgery. In addition, the QLB2 group presented reduced postoperative opioid consumption at 24 h (SMD: –0.45; 95% CI: –0.86, –0.03; p = 0.03; I 2 = 78%; GRADE = moderate). The subgroup analyses revealed that the analgesic benefit of QLB2 did not persist beyond 24 h when the patients were under spinal anesthesia. Conclusion Ultrasound-guided QLB2 could provide effective analgesia for patients under general anesthesia by decreasing the intensity of pain and opioid requirement when used within 24 h after abdominal surgery.
