Introduction: Ketamine is a medication that suppresses the central nervous system and can be used as an analgesic. The aim of this study is to compare the post-operative pain reduction of rectal ketamine and caudal bupivacaine in pediatric lower abdominal surgery. Materials and Methods: This double-blind clinical trial was performed on 68 children aged 1-7 years whom were allocated into two groups of 34 patients. The first Group received rectal ketamine (2mg/kg), and the second received 0.75mg/kg caudal bupivacaine (0.125%). Mean pain intensity and hemodynamic variables were recorded 2,6,12 and 24 hours following lower abdominal surgery in children. Pain was assessed using FLACC (Face, Legs, Activity, Cry, Consolability) Scale. Results: There were no significant difference in terms of pain intensity between admission and discharge from recovery (p>0.05). Patients who received ketamine endured less pain than bupivacaine 2, 6, and 12 hours following surgery (p<0.05). Mean extubation time and duration of recovery stay was significantly shorter in the ketamine group. Conclusion: Rectal ketamine was associated with more effective pain control and shorter recovery stay, when compared to caudal bupivacaine in lower abdominal pediatric surgery.
