Context: To assess the analgesic efficacy of the combination of bupivacaine and buprenorphine in alleviating postoperative pain following laparoscopic cholecystectomy.
Aims: Laparoscopic cholecystectomy is comparatively advantageous as it offers less pain in the postoperative period and requires a shorter hospital stay. There are only a few studies performed to evaluate the analgesic efficacy of intraperitoneal instillation of buprenorphine and bupivacaine during laparoscopic cholecystectomy.
Settings and design: The present research is a randomized, double-blind controlled study conducted in the Department of Anaesthesiology, Dayanand Medical College and Hospital Ludhiana, Punjab after formal ethical approval from Hospital's Ethics Committee.
Subjects and methods: This study analyzed 90 adults admitted for elective laparoscopic cholecystectomy. After the procedure, subjects were divided into three equal groups to conduct the study. Three Groups A, B, and C had intraperitoneal instillation of the 25 ml of physiological saline (0.9% normal saline), 0.25% of bupivacaine, 0.25% bupivacaine, and 0.3 mg buprenorphine, respectively. Necessary vitals were monitored and recorded. Visual analog scale (VAS) and verbal rating scale (VRS) scores were recorded and analyzed systematically.
Statistical analysis used: All observations were analyzed using analysis of variance and Student's t-test.
Results: The mean pain scores were highest in Group A compared to Group B and Group C. Mean VAS and VRS scores were highest in Group C comparatively and lowest in Group A.
Conclusion: Combination of buprenorphine and bupivacaine intraperitoneally is comparatively more effective in relieving postoperative pain in comparison to intraperitoneal instillation of bupivacaine alone for postoperative pain management after laparoscopic cholecystectomy.
