摘要
目的：在吸入麻醉术后恢复阶段，观察回路内麻醉气体吸附器是否可缩短吸入麻醉的苏醒时间。方法：在固定潮气量、每分通气量和新鲜气体流量的条件下，术毕关闭挥发罐后，比较使用回路内麻醉气体吸附装置对回路内麻醉气体浓度变化的影响。结果：使用吸附器后，回路内麻醉气体浓度降至ＭＡＣ ０．３所需时间，异氟醚由２０．０± ０．３分钟降至３．３±０．５分钟（Ｐ＜０．０１）。安氟醚由２５．０±０．１分钟降至３．５ ± ０．５分钟（Ｐ＜０．０１）。结论：应用回路内麻醉气体吸附器可显著缩短病人苏醒时间，并减少气源浪费和环境污染。
Objective: To observe whether the in-flow anesthetic gas absorber can reduce the recovery time after stopping inhalation of enflurane or isoflurane. Methods: In fixed tidal volume, minute volume and fresh gas flow, the recovery time of isoflurane or enflurane anesthesia with or without in-flow anesthetic gas absorber were compared after closing the vaporizer. Results: With in-flow anesthetic gas absorber, the time for anesthetic gas concentration in circle to reduce the MAC to 0. 3was 3. 3 ±0. 5 min for isoflurane, which was significntly shorter than that without absorber(20 ±0. 3min) (P < 0. 01 ) and the time for enflurane was 3. 5 ± 0. 5min and 25 ± 0. 1min respectively. Conclusion: Anesthetic gas absorber can reduce the recovery time of either enflurane or isoflurane inhalational anesthesia significantly.
