Efficacy of Local Anesthetic in Post-Operative Laparoscopic Cholecystectomy

Abstract

Background: Pain management is medically pertinent for optimal care in surgical patients. Although development and advancement in understanding of the pathophysiology of pain, analgesic's pharmacology and the development of better effective techniques for postoperative pain control, patients still continue to experience considerable discomfort. Objectives: To compare the efficacy (in terms of pain) of local anesthetic in postoperative laparoscopic cholecystectomy compared to control group. Methods: A total of 60 patients undergoing laparoscopic cholecystectomy and of age 20-50 year were included. Group A included the cases in which at the end of laparoscopic surgery, prior to port withdrawal, a local anesthetic mixture, a short acting (Lidocaine 2%) plus a long acting (Bupivacaine 0.5%) was instilled through the port lumen between the abdominal wall layers while group B included the cases in which conventional analgesics (narcotics and NSAID) was given post - operatively. All the patients were assessed by the researcher himself up to 12 hours post-operatively and efficacy was noted by Visual Analogue Scale (VAS). This study was conducted in Department of surgery Quaid e Azam Medical College Bahawalpur. Duration of study was 1 year from August, 2018 to August, 2019. Results: Efficacy in control of pain of Group A (local anesthetic) was seen in 22(73.33%) while in Group B (control group) was seen in07 (23.33%) patients as shown in Table VI (p- value = 0.0001). Conclusion: The study concluded that the efficacy of local anesthetic in postoperative laparoscopic cholecystectomy is better as compared to control group.
