目的 :研究笑气吸入性镇痛用于人工流产术的疗效。方法 :将采用笑气吸入镇痛行人流术 2 0 0例作为观察组 ,同期采用利多卡因宫颈神经阻滞麻醉行人流术 2 0 0例作为对照组 ,分别观察镇痛效果、镇痛起效时间、手术时间、出血量、血氧饱和度及不良反应。结果 :两组镇痛效果比较差异有显著性 (P<0 .0 1) ,两组镇痛起效时间比较差异有统计学意义 (P<0 .0 5 ) ,两组手术时间、出血量、血氧饱和度差异无显著性 (P>0 .0 5 )。结论 :笑气吸入性镇痛用于人工流产术镇痛效果好 ,镇痛作用起效快 ,病人不良反应少 ,适合人流手术需要
Objective: To study the efficacy of inhalation analgesia with nitrous oxide for artificial abortion. Methods: A total of 200 cases of pedestrian abscess with inhalation of nitrous oxide were selected as the observation group. 200 cases were treated with lidocaine cervical nerve block anesthesia during the same period as the control group. The analgesic effect, Effective time, operation time, blood loss, oxygen saturation and adverse reactions. Results: There was significant difference in analgesic effect between the two groups (P <0.01). There was significant difference in the onset time of analgesia between the two groups (P <0.05), the operation time and the amount of bleeding , No significant difference in oxygen saturation (P> 0.05). Conclusions: Inhalation analgesia of nitrous oxide is effective for analgesia induced by induced abortion, with rapid onset of analgesic effect, few adverse reactions and suitable for abortion
