Evaluation of ultrasound-guided quadratus lumborum block for post-operative analgesia in unilateral laparoscopic renal surgeries – A randomised controlled trial

Abstract

Background and Aims: Quadratus lumborum block (QLB) is a novel anaesthetic technique for abdominal wall block providing excellent post-operative analgesia. The primary objective of this study was to evaluate the duration of post-operative analgesia with QLB in unilateral laparoscopic renal surgeries. The secondary objectives were to assess total morphine consumption during the first 24 h postoperatively and observe for complications. Methods: Sixty patients undergoing unilateral laparoscopic renal surgeries were randomly divided into two groups, with patients receiving QLB (Group A) or no block (Group B) at the end of surgery. General anaesthesia was standardised in both the groups. The pain was assessed by a Visual Analogue Scale (VAS) of 1–10. The duration of analgesia was taken as time from extubation to VAS of ≥3. Morphine was administered in patient-controlled analgesia pump with a bolus of 1 mg and a lockout interval of 10 min (min). The total morphine consumption was recorded. The statistical analysis was performed with the Student's t -test and Chi-square test. Results: The duration of post-operative analgesia was significantly prolonged in Group A (1288 ± 288.92 min) than Group B (138 ± 54.92 min). Morphine consumption was also less in Group A (3.1 ± 0.87 mg) than Group B (10.46 ± 1.8 mg). There was a significant difference in the VAS score from 16 to 20 h. No complications were recorded. Conclusions: Ultrasound-guided QLB after laparoscopic renal surgery is safer to perform, effective with an increased post-operative duration of analgesia, reduces the consumption of opioids and is associated with fewer side effects.

“…49 These benefits appear to apply to both laparoscopic approaches as well as open approaches. 50 The use of QL blocks has also been demonstrated in pediatric patients undergoing renal transplantation, although this study of 32 patients did not include a control group for comparison. 26…”

“…These may have side-effects like nausea, vomiting, pruritus, and respiratory depression. 1,2 Mandibular nerve block provides good perioperative analgesia for mandibular and intra-oral surgeries. They can be used as part of multimodal analgesia to reduce the consumption of opioids in the postoperative period.…”
