Background and Aims: Intraperitoneal local anesthetic is an effective analgesic approach in laparoscopic appendectomy in adults. The aim of the study was to compare the postoperative pain when intraperitoneal bupivacaine is administered alone versus the addition of dexmedetomidine to it in children undergoing a laparoscopic appendectomy. Methods: In this prospective randomized trial, 52 children were randomly allocated to Group B who received intraperitoneal bupivacaine 0.25% (2 mg/kg) or Group BD who received intraperitoneal bupivacaine 0.25% (2 mg/kg) plus dexmedetomidine (1 mcg/kg) for postoperative analgesia in children undergoing laparoscopic appendectomy. Postoperative pethidine consumption at day 1 was recorded and considered the primary outcome of the study. Patients were evaluated for pain scores at 0, 2, 4, 6, 12, and 24 h, time to first request of pethidine, sedation scores at 0, 2, 4, and 6 h, length of hospital stay, and parents' satisfaction. Chi-square, Fisher's exact, Student's t-test, and Mann–Whitney U-tests were used for analysis. Results: Postoperative visual analog scale scores were lower in Group BD at 2, 4, and 6 h (mean = 3, 3, 3, respectively) compared with Group B (mean = 4, 5, 4, respectively) (P < 0.05). Patients in Group BD had more sedation scores at 0, 2, and 4 h (P < 0.05), longer time to first rescue analgesia (P = 0.03), lesser rescue analgesic consumption (P = 0.02), shorter length of hospital stay (P = 0.02), and higher parents' satisfaction (P = 0.01). Conclusion: Adding dexmedetomidine to intraperitoneal bupivacaine provides adequate postoperative analgesia in children undergoing laparoscopic appendectomy.
