Aim: To compare ultrasound-guided transversus abdominis plane block with bupivacaine and ropivacaine as adjuncts for postoperative analgesia in laparoscopic cholecystectomies. Methodology: Eighty- four American Society of Anaesthesiologists physical status I/II patients aged 18–70 years who underwent laparoscopic cholecystectomy of either genderwere randomly divided into 2 groups of 42 each. Group 1patients underwent ultrasound-guided TAP block with 0.25% bupivacaine (plain) and group 2patients underwent ultrasound-guided TAP block with 0.375% ropivacaine (plain). Parameters such as the consumption of rescue analgesics and post-operative pain at 10 minutes, 30 minutes, 1 hour, 4 hours, 8 hours, 12 hours, and 24 hours was recorded. Results: Group 1 had 20 males and 22 females and group 2 had 21 males and 21 females. The mean weight of patients in group 1 was 65.2 kgs and in group 2 was 66.2 Kgs. The mean height was 157.2 cms in group 1 and 158.4 cms in group 2. The mean duration of surgery was 71.4 minutes in group 1 and 74.6 minutes in group 2. Number of patients requiring analgesics was 38 in group 1 and 32 in group 2. The difference was non- significant (P> 0.05). In both groups, at 10 minutes, the mean pain score at was 0. At 30 minutes, it was 1.9 in group 1 and 0.0 in group 2. At 1 hour was 3.0 in group 1 and 0.0 in group 2. At 4 hours was 2.6 in group 1 and 2.8 in group 2. At 8 hours was 2.2 in group I and 2.5 in group 2. At 12 hours was 1.6 in group 1 and 2.3 in group 2. At 24 hours was 1.2 in group 1 and 1.4 in group 2. Conclusion: In comparison to bupivacaine 0.25%, ultrasound-guided deposition of ropivacaine 0.375% in the TAP gave patients undergoing laparoscopic cholecystectomy better analgesia in the early post-operative period.
