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
