无痛人工流产术应用氧化亚氮镇痛效果的临床观察

目的：探讨氧化亚氮吸入麻醉在人工流产术中的镇痛效果。方法：选择人工流产术共300例，随机分为氧化亚氮组150例，对照组150例。观察两组的人流综合征（PAAS）发生率、手术时的疼痛、术中出血量、术后宫缩幅度及副反应。结果：氧化亚氮组PAAS发生率和手术时疼痛显著低于对照组（P〈0．01），手术时的出血量和术后宫缩幅度两组间无明显差异（P〉0．05）。结论：氧化亚氮吸入法简单、迅速、安全、有效，是无痛人流较理想的镇痛方法。

Clinical observation of analgesic effects with inhaling N2O during the induced abortion

Objective：To investigate the analgesic, effects with inhaling N2O during the induced abortion. Methods：Three hundred cases induced abortion patients were randomly divided into two groups ：N2O group 150 cases ,comparison group 150 cases. The rate of PAAS,pain during operation,quantity of hereorrhage during operation, uterine construction amplitude after operation and side effects of two groups were observed. Results ： The rate of PAAS and pain during operation of N2O group were statistically lower than of comparison group （P〈0.01）. There are nodistinct differerce on quantity of hemorrhage during operation and merine construction ampl itutde after operation between two groups（P〉0.05）. Conclusion ：Inhaling N2O during the induced abortion is a effective analgesic method with the advantage of simple,safty and prompt,which is the preferably method for the induced abortion with no pain.
