Background: Effective post-operative pain control is an essential component of the care of the surgical patient. Certain patient population are at risk of in-adequate pain control and requires special attention, including pediatric patients, geriatric patients and patients with difficulty in communication. Objectives: To compare quality and duration of analgesia, motor and sensory block after caudal block with either Bupivacaine or Ropivacaine in pediatric cases aged 2–6 years. Materials and Methods: An observational study with consecutive sampling technique getting either of two interventions are recruited till the sample size is attained. 74 pediatric patients planned for circumcision with ASA1 allocated in two different groups, to receive either 0.375% ropivacaine or 0.375% bupivacaine. Onset of action and return of motor movements assessed based on Bromage scale. Mean duration of onset of anesthesia, duration of motor blockade and post-operative analgesia among two groups are compared using t-test. Proportions of children with adverse effect among two groups are compared using Chi-square test. Results: Both the groups were comparable regarding age, weight, onset of action and post-operative analgesia but significant difference was noted in return of motor movements in both groups. Conclusion: Not much significant difference observed in the post-operative analgesia among the study groups. As regard to the motor function recovery is much faster with ropivacaine than with bupivacaine.
