Clinical effect of sufentanil and levobupivacaine on postoperative analgesia in pediatric caudal block anesthesia

Abstract

Objective To invetigate the effect and safety of sufentanil mixed levobupivacaine on postoperative analgesia in pediatric caudal block anesthesia.Method Sixty pediatric patients (2 ～ 6 years old) who were undergoing elective abdominal surgery,such as repair hernia of high ligation,were randomly divided into three groups with 20 cases each.after intravenous induction,0.25％ levobupivacaine was injected in sacrum tube in group Ⅰ,0.5 μg/ml sufentanil mixed 0.25％ levobupivacaine and 1.0 μg/ml sufentanil mixed 0.25％ levobupivacaine were injected in sacrum tube in group Ⅱ and group Ⅲ respectively.The analgesia effect,the analgesia time,recover time and adverse reaction were observed and recorded 2,4,8,12,16,24 hours after the surgery.Results The analgesia effect in group Ⅱ、Ⅲ were significantly better than the group Ⅰ when 4、8、12 hours after the operation(P ＜0.05),and the analgesia effect in groupⅢ were significantly better than the group Ⅱ when 8 hours after the operation (P ＜ 0.05).There were no significant differences in three groups when 2、16、24 hours after the operation(P ＞0.05),the analgesia time in group Ⅱ、Ⅲ were significantly longer than the group Ⅰ (P ＜ 0.05),and the analgesia time in group Ⅲ were significantly longer than the group Ⅱ (P ＜ 0.05).There were no differences in the recovery time of three groups (P ＞ 0.05).There were no adverse reactions in three groups.Conclusions 0.5 μg/ml and 1.0 μg/ml sufentanil mixed 0.25％ levobupivacaine may be used on postoperative analgesia in pediatric caudal block anesthesia safely and analgesia effect and time were more better and longer than 0.25％ levobupivacaine singly.The analgesia effect in group with 1.0μg/ml sufentanil mixed 0.25％ levobupivacaine was the best in three groups with the fewest side effects.
