Efficacy of Intraperitoneal Bupivacaine on Pain Relief After Laparoscopic Cholecystectomy

Introduction: Patients undergoing laparoscopic cholecystectomy do experience postoperative pain, especially in the abdomen. Postoperative pain management remains a major challenge after laparoscopic procedures. Administration of intraperitoneal local anesthetic (IPLA) after surgery is used as a method of reducing postoperative pain. In this study, we evaluated the effect of intraperitoneal infiltration of local anesthetic (bupivacaine) for pain relief after laparoscopic cholecystectomy.

Material and methods: In this prospective, controlled, and randomized study were included 50 patients aged 25-60 years (35 female and 15 male), scheduled to laparoscopic cholecystectomy with ASA classification 1 and 2. Patients were classified randomly into two groups: group A, which included 25 patients who received intraperitoneal instillation of bupivacaine 0.5% 20 ml; and group B, which included 25 patients who didn’t receive any intraperitoneal instillation. Postoperative pain was recorded using the visual analogue scale (VAS) for 24 hours after laparoscopic cholecystectomy.

Results: There was no significant difference with respect to age, weight, and sex; duration of surgery; and anesthesia time. VAS scores at different time intervals were statistically significantly lower at all times in group A compared to group B. There were statistically significant differences in VAS scores between group A and group B at all postoperative time points - 1hr,4 hr,8 hr,12hr and 24hr (p < 0.00001).

Conclusion: Intraperitoneal instillation of bupivacaine provides good analgesia in the postoperative period after laparoscopic cholecystectomy.
