A COMPARISON BETWEEN INSTILLATION OF INTRAPERITIONEAL BUPIVACAINE & MORPHINE vs. BUPIVACAINE ALONE IN ANALGESIA AFTER LAPAROSCOPIC CHOLECYSTECTOMY
Abstract Background Pain after laparoscopic cholecystectomy remains a challenging issue to this relatively less invasive surgery, In this study we try to tackle this problem through intraperitoneal injection of drugs particularly morphine and bupivicaine to reduce post-operative pain. Objectives The Aim of this study is to assess postoperative pain in laparoscopic cholecystectomy by comparing between administering intraperitoneal bupivacaine alone versus intraperitoneal bupivacaine with intravenous morphine; Using the VAS scale and measuring time for rescue analgesic administration. Methods and material This prospective double blinded randomized clinical trial study was conducted in Ain Shams University hospital after approval of the anesthesia department and the local ethics and research committee over 6 months and after obtaining a written informed consent. Sixty patients underwent laparoscopic cholecystectomy were included in the study their ages range between 18 and 60 years old and classified as ASA I and II. The patients were randomly divided using computer generated randomization into two groups 30 patients in each (n = 30), Group BM received 30 ml of mixture of bupivacaine and 2 mg morphine while group BO received bupivacaine only Results This study showed that Morphine bupivacaine admixture had made dramatic decline in shoulder and abdominal pain VAS scores specifically at the 18th and24th hour; 15 patients in the BM group had either VAS score zero or 1 when compared to BO group whom their scores at the 18th and 24th hour was between 4 and 8. Also, there was more decrease in postoperative analgesic consumption in BM group. Conclusions We conclude that intraperitoneal instillation of 2 mg to bupivacaine 0.5% in elective LC significantly reduced post-operative shoulder pain and analgesic requirement when compared to bupivacaine 0.5% alone.
