RESUMEN
Background: Instillation of intraperitoneal lignocaine, bupivacaine, levobupivacaine, and ropivacaine has been used followinglaparoscopic gynecological and general surgical procedures to reduce post-operative pain through randomized trials formany years. Hence, the present study was undertaken for assessing and comparing the efficacy of intraperitoneal instillationof levobupivacaine (0.25%) and ropivacaine (0.25%) for post-operative analgesia in patients undergoing laparoscopiccholecystectomy (LC).Materials and Methods: Ninety patients were enrolled and were randomly divided into three groups of 30 each. Group L:Patients were given 20 ml of 0.5% levobupivacaine plus dexmedetomidine at 1 μg per kg body weight and making total volume40 ml by adding normal saline (NS), intraperitoneally after gallbladder removal. Group R: Patients were given 20 ml of 0.5%ropivacaine plus dexmedetomidine at 1 μg per kg body weight and making total volume 40ml by adding NS, intraperitoneallyafter gallbladder removal. Group C: Patients were given 40 ml of NS. Postoperatively, the patients were assessed for painutilizing visual analog scale (VAS). The results were statistically analyzed using latest software.Results: The mean VAS score reading was lower in Group L and Group R in comparison to Group C at all the time intervals. Thenumber of patients requiring rescue analgesia was significantly higher in Group C in comparison to other study groups. Amongthe L group and R group, the number of patients requiring rescue analgesia was lower in Group L in comparison to Group R.Conclusion: Intraperitoneal instillation of local anesthetic solution in LC provided effective post-operative analgesia, butanalgesia provided by levobupivacaine plus dexmedetomidine was significantly better than ropivacaine plus dexmedetomidine
