Background: Alpha-2 adenoreceptors as an adjuvant to local anesthetic during caudal analgesia in children prolongs the duration of analgesia. This study was designed to compare the analgesic efficacy and adverse effects of dexmedetomidine and clonidine when added to ropivacaine for caudal analgesia in children undergoing lower abdominal surgeries. Methods: In a prospective study, Seventy-eight children received block with either 0.2% ropivacaine 1.5 mg/kg (Group R; n = 26) or 0.2% ropivacaine 1.5 mg/kg + 1 mcg/kg clonidine (Group RC; n = 26) or 0.2% ropivacaine 1.5 mg/kg + dexmedetomidine 1 mcg/kg (Group RD; n = 26). Results: Duration of analgesia was 7.15 ± 1.00 h in Group R, 11.57 ± 1.27 h in Group R + C, and 14.73 ± 1.53 h in Group R + D (P < 0.0001). One patient in Group R + D had vomiting and 1 patient in Group R had urinary retention which was not statistically significant (P > 0.05). Conclusion: Addition of clonidine and dexmedetomidine to caudal ropivacaine significantly prolongs the duration of analgesia without adverse effects.
