Background: Caudal Anesthesia has becomed a reliable and effective anesthetic technique in pediatric patients but the drawback is the limited duration of action of local anesthetic agents used in caudal block, has now overcome by using adjuvants in the clinical settings. Aim: We compare the analgesic effects and side effects of Fentanyl and dexamethasone added to ropivacaine with ropivacaine alone in paediatric patients undergoing subumibilical surgeries. Setting & design: This was a prospective, randomized Double-blinded study, involving 111 no of ASA I & II pediatric patients. Material & Methods: one hundred eleven patients (3- 10 years) were evenly and randomly assigned into 3 groups in double-blind manner. Group R received 1mg/kg of 0.25% ropivacaine diluted in saline. Group D received 1mg/kg of 0.25% ropivacaine with 0.1mg/ kg of dexamethasone . Group F received 1mg/kg of 0.25% of Ropivacaine with 1u/kg Fentanyl. Result: The duration of postoperative analgesia and pain score was less in dexamethasone group and less number of patients required analgesia in dexamethasone group as compared to Fentanyl and ropivacaine groups. More sedation and significant number of adverse effects was present in the Fentanyl group. Conclusion: Addition of dexamethasone and Fentanyl to caudal ropivacaine significantly prolongs analgesia and are good alternatives, but dexamethasone have superior analgesia and less adverse effects as compare to Fentanyl.
