目的:探讨异丙酚辅助小儿骶管阻滞在下腹部及会阴部手术的应用效果。方法:选择下腹部及会阴部手术患儿60例。随机分成两组:异丙酚辅助骶管阻滞麻醉组[观察组(A)]和氯胺酮麻醉组[对照组(B)]。A组用0.2%罗哌卡因1 mg/kg骶管阻滞,异丙酚复合静脉麻醉。B组以肌内注射氯胺酮4 mg/kg,同时给以0.04～0.06 mg/kg咪达唑仑,根据睡眠深度及应激反应追加氯胺酮。结果:B组在术中探查时HR、RR明显优于A组(P<0.05),存在统计学差异。结论:异丙酚复合骶管麻醉用于小儿下腹部手术是一种镇痛完善、血流动力学稳定、苏醒快、术后镇痛的安全实用麻醉。
Objective: To investigate the effect of propofol-assisted pediatric caudal block in lower abdomen and perineal surgery. Methods: Sixty children with lower abdomen and perineal operation were selected. Randomized into two groups: propofol-assisted caudal block anesthesia [observation group (A)] and ketamine anesthesia [control group (B)]. A group with 0.2% ropivacaine 1 mg / kg caudal block, propofol intravenous anesthesia. In group B, ketamine 4 mg / kg was intramuscularly injected, and midazolam 0.04 to 0.06 mg / kg was administered. Ketamine was added according to the depth of sleep and the stress response. Results: HR and RR were significantly better in group B than those in group A (P <0.05). There was a statistically significant difference. Conclusion: Propofol combined caudal anesthesia for pediatric lower abdominal surgery is a safe and practical anesthesia with perfect analgesia, stable hemodynamics, fast recovery and postoperative analgesia.
