目前小儿疝囊高位结扎术多在骶管麻醉辅以静脉全身麻醉下完成,虽操作简单,但仍存在穿刺困难、局部麻醉药误入血管的可能性。本试验以雷米芬太尼联合丙泊酚行全凭静脉麻醉,观察患者麻醉中的血流动力学变化情况、术后苏醒时间、术中体动发生率,以探讨小儿疝囊高位结扎术较合适的静脉麻醉方法。 At present, the high ligation of pediatric hernia sac is mostly performed under the caudal anesthesia combined with intravenous general anesthesia. Although the operation is simple, there is still the possibility of puncturing local anesthetic into the blood vessel. This experiment with remifentanil combined with propofol, total intravenous anesthesia, anesthesia in patients under observation of hemodynamic changes, postoperative recovery time, intraoperative physical activity, to explore the high incidence of pediatric herniation ligation More appropriate method of intravenous anesthesia.
