【 摘 要 】

Aim: The aim of our study was to compare the efficacy and duration of analgesia of caudally administered0.2% ropivacaine with 0.2% bupivacaine along with recovery of motor and sensory blockade in pediatricpatients undergoing infraumbilical surgery.Methodology: In this prospective, double blind study, 60 pediatric patients planned for infraumblicalsurgery, of ASA grade I or II, were randomly allocated in two different groups to receive 1 ml/kg of either0.2% ropivacaine (Group A) or 0.2% bupivacaine (Group B) via caudal route after induction of generalanesthesia. Objective pain score (OPS) and total duration of analgesia along with rescue analgesia werecompared in both the groups. Recovery of motor and sensory blockade was also noted. The results wereanalyzed statistically using student’s paired t-test for intergroup comparison and chi square test for nonparametricdata or complications.Result: Both the groups were comparable regarding age, weight, sex distribution and duration ofsurgery. Patients remained hemodynamically stable during intraoperative period in both the groups.The maximum mean sedation score at the beginning of the stay in the recovery room was 0.60 ± 0.67and 0.67 ± 0.71 in Group A and B respectively. Though the OPS were marginally higher in Group B ascompared to Group A but the differences in total duration and quality of analgesia were not statisticallysignificant. Average duration of analgesia was 390.2 ± 35.16 min and 377.0 ± 34.41 min in Group A andB respectively. However, motor recovery was faster in ropivacaine group with MPS of 10.00 ± 0.00 incomparison to 8.80±0.99 in bupivacaine group (P value <0.01) at 2 hours in postoperative period.Conclusion: Caudal ropivacaine 0.2% is equally effective local anesthetic agent when compared tocaudal bupivacaine 0.2% in terms of postoperative analgesia, but with faster motor recovery in pediatricpatients.
