Effect of Intraperitoneal Bupivacaine with Dexmedotomidine or Fentanyl for Post-Operative Analgesia Following Laparoscopy in Pediatric Patients

To compare analgesic effect of adding dexmedomedin or fentanyl to intraperitoneal bupivacain in pediatric patients undergoing laparoscopy. The primary outcome is to compare pain using the Children's Hospital of Eastern Ontario score (CHEOPS). The secondary goal is to compare the time to the first request for analgesia in the post-operative period, the total dose of analgesics used in the 24 hours (post-operative), side effects, and signs of systemic absorption and toxicity.
