Abstract

Objective: To evaluate the effectiveness of ultrasound guided posterior quadratus lumborum (QL) block against multimodal analgesics for post-operative pain in patients undergoing laproscopic cholecystectomy.

Study Design: Quasi-experimental study.

Place and Duration of Study: Sheikh Khalifa Bin Zayed Al Nahyan Hospital/Combined Military Hospital (SKBZH-CMH), Muzaffarabad, Pakistan, from Jan to Jun 2024.

Methodology: After seeking permission of hospitals ethical committee this Quasi-experimental study was performed with a sample of fifty patients undergoing laproscopic cholecystectomy. The Groups were named as Group Q and Group P after randomization. At the end of surgery, the patients comprising Group Q were given quadratus lumborum block and patients in Group P were given local wound infiltration of local anesthetic along with intravenous ketorolac 30mg. The primary outcome variable was time to first analgesic request.

Results: The mean time to first analgesic request (FAR) in Group Q patients was 9.26±2.21 hours and the mean time to first analgesic request (FAR) in Group M patients was 3.66±1.37 hours with p value of less than 0.001. There were 24(92.3%) patients who were satisfied with linker score greater than four in Group Q while only 2(7.7%) patients conveyed dissatisfaction.  There were 9(37.5%) patients who were satisfied with linker score greater than four in Group M while 24(62.5%) patients were not satisfied with p-value <0.001.

Conclusion: We arrived at the conclusion that quadratus lumborum block prolongs the time to breakthrough pain in patients with laproscopic cholecyctectomy compared to intravenous multimodal analgesia.
