AbstractBackground: Caudal epidural anaesthesia blocks dermatomes below the level of the umbilicus in children.
Objectives:This study intends to compareropivacaine and bupivacaine for caudal anaesthesia in children undergoing lower abdominal surgery.
Materials and methods: After the hospital ethics committee approval, 60 (ASA I–II) children scheduled for lower abdominal surgery were included in this study. Group A (n=30) patients received ropivacaine 0.25% and group B (n = 30) patients received bupivacaine 0.25% via the caudal route. We assessed the demographic and clinical characteristics, AIIMS pain score at 1, 2, 4, 8, 12, 16 and 24 hours after operation and level of residual motor block (Bromage Scale)immediately after surgery and at 1, 2 and 3 hours post operatively.Data analysis was performed using one way ANOVA test.P value less than 0.05 was considered significant.
Results and conclusion: There were no statistically significant differences in AIIMS pain scores between groups A and B at all postoperative time points –1hr, 2hr, 4hr, 8hr, 12hr, 16hr and 24hr(P < 0.00001). The quality and duration of analgesia were comparable in both the groups. However, degree of motor block was significantly less in the ropivacaine group. After 3 hours there was no significant difference in the level of residual motor block.
The single shot caudal epidural block with 1ml/kg ropivacaine 0.25% is a safe and effective, long lasting dose for postoperative analgesia in paediatric lower abdominal surgery, producing less duration of motor block than bupivacaine 0.25%.
