目的 采用双盲法观察不同麻醉维持方法麻醉后期的恢复情况。方法 30 例择期手术的病人,ASA Ⅰ~Ⅱ级,随机分为三组:安氟醚组、异丙酚组及复合组,每组10 例。安氟醚组以1%~2% 安氟醚吸入维持麻醉,异丙酚组以注射泵经静脉持续输注异丙酚6~12m g·kg- 1/h 维持麻醉,复合组吸入1% 安氟醚并静脉输注异丙酚6~9m g·kg- 1/h。结果 安氟醚组的术后呼吸、吞咽反射、呼之睁眼恢复时间明显短于其它二组( P< 0.05 或P< 0.01);术后拔管时间复合组明显长于其它二组(P< 0.01);呼吸道梗阻的发生率三组相同;停药-定向力恢复时间三组相同,但拔管-定向力恢复时间复合组明显高于其它二组( P< 0.05)。结论 从术后恢复角度看,安氟醚与静脉异丙酚复合维持麻醉是不合理的
Objective To observe the recovery of anesthesia in different anesthesia maintenance methods by double-blind method. Methods Thirty patients undergoing elective surgery were randomly divided into three groups: enflurane group, propofol group and compound group, with 10 cases in each group. In the enflurane group, anesthesia was maintained by inhalation of 1% ~ 2% enflurane, propofol was continuously infused intravenously into the propofol group for 6 ~ 12 m g · kg-1 / Andaflurane and intravenous propofol 6 ~ 9m g · kg-1 / h. Results The recovery time of respiration, swallowing reflex, and eye opening in the enflurane group was significantly shorter than those in the other two groups (P <0.05 or P <0.01). The time of extubation in the enflurane group was significantly longer than that in the other two groups (P <0.01). The incidence of airway obstruction was the same in the three groups. The recovery time of the withdrawal-directed force was the same in the three groups, but the recovery time of extubation-oriented force in the composite group was significantly higher than the other two groups (P <0.01). 05). Conclusion From the perspective of postoperative recovery, the combination of enflurane and intravenous propofol is not reasonable
