乙醚吸入与戊巴比妥钠腹腔注射联合麻醉的应用

目的探讨乙醚吸入与戊巴比妥钠联合麻醉应用效果。方法随机将20只受肝大鼠分成两组，每组10只。A组为单纯的乙醚吸入麻醉对照组，B组先用乙醚吸入作麻醉诱导，再腹腔注射2％戊巴比妥钠作麻醉维持。观察手术时间、术中追加麻醉次数、术后苏醒时间和死亡率。结果与B组相比，A组手术时间明显延长（P〈0．05），术中平均需要重复吸入乙醚5±1．63次，以维持麻醉状态。B组术中麻醉平稳，不需要继续给药．两组术后苏醒时间无显著性差异（P〉0．05）。结论乙醚吸入与戊巴比妥钠联合麻醉，可延长麻醉的有效时间，加强麻醉效果，有效地保证手术的顺利进行。

Application of Anaesthesia with Combined Ether Inhalation and Sodium Pentobarbital Intraperitoneal Injection to Rat Liver Transplantation

Objective To study the effect of anaesthesia with combined ether inhalation and sodium pentobarbital intraperitoneal injection to rat liver transplantation. Method 20 liver receiving rats were randomly divided into 2 groups, received 2 methods of anaesthesia with ether inhalation （group A, n = 10） and ether inhalation plus 2% sodium pentobarbital intraperitoneal injection （group B, n = 10） respectively. The time needed for operation and for recovering consciousness after operation, the times of intraoperative anaesthesias and the death rate were observed. Results The anaesthesia was more stable in group B than that in group A with no more intraoperative anaesthesia and a shorter operation time, but no significant difference was found in the postoperative awakening time （ P 〉 0.05 ）. Conclusion It is a better way to administer ether inhalation in combination with sodium pentobarbital intraperitoneal injection in anaesthesia.
