目的:探讨笑气镇痛人工流产术前1 h口服米索前列醇400μg,术中B超实时引导对缩短手术时间、减少术中出血、降低手术并发症的作用。方法:选择自愿人工终止妊娠的健康早孕妇女180例,随机分为米索前列醇组、米索前列醇+B超组、对照组,观察宫颈口扩张程度、手术时间、术中出血量、手术并发症。结果:米索前列醇组和米索前列醇+B超组的宫颈扩强程度好于对照组(P<0.01),手术时间及术中出血量均显著减少(P<0.01),米索前列醇+B超组未发生手术并发症。结论:笑气镇痛人流术前1 h口服米索前列醇400μg,术中B超实行引导能明显缩短手术时间,减少术中出血,降低手术并发症,值得在临床中推广。
Objective: To investigate the effect of oral administration of misoprostol 400 μg 1 h before artificial gastrocnemius induced abortion in patients with short-term operative time, reduce intraoperative blood loss and surgical complications. Methods: One hundred and eighty healthy pregnant women were randomly divided into misoprostol group, misoprostol + B group and control group. The degree of cervical dilatation, operation time, intraoperative blood loss, operation complication. Results: The misdiagnosis rate of misoprostol and misoprostol + B group was significantly higher than that of the control group (P <0.01). The operation time and blood loss were significantly decreased (P <0.01) Alcohol + B super group did not have surgical complications. Conclusions: Misoprostol 400 μg was administrated 1 h prior to abortion in patients with nausea and nocturnal gastritis. The guided operation of B ultrasound can shorten the operation time, reduce the intraoperative bleeding and reduce the complications of surgery. It is worth to be popularized clinically.
