目的观察B型超声引导下米非司酮联合微管在早早孕无创人工流产中的效果和临床用药特点。方法将100例行无创人工流产手术的早早孕患者随机分为2组。观察组50例采用米非司酮联合微管在B型超声引导下行人工流产手术,对照组50例采用微管的一次性宫腔组织吸引管行人工流产手术。比较2组孕妇流产率、疼痛程度、手术时间、孕囊排出时间、出血时间、复经时间及不良反应。结果观察组完全流产率高于对照组,不完全流产率低于对照组,差异均有统计学意义(P<0.05)。观察组疼痛程度低于对照组,观察组手术时间、孕囊排出时间、出血时间和复经时间明显短于对照组,差异均有统计学意义(P<0.05)。2组不良反应发生率比较差异无统计学意义(P>0.05)。结论 B型超声引导下米非司酮联合微管在早早孕无创人工流产中的效果显著,值得临床推广应用。
Objective To observe the effect of B-mode ultrasound-guided mifepristone combined with microtubules in the induction of early pregnancy induced abortion and its clinical characteristics. Methods One hundred cases of early pregnancy with noninvasive abortion were randomly divided into two groups. Fifty patients in the observation group underwent guided abortion with B-mode ultrasound guided by mifepristone combined with microtubules. In control group, 50 patients underwent unilateral intrauterine catheterization with microtubules for induced abortion. The abortion rate, pain degree, operation time, gestational sac discharge time, bleeding time, relapse time and adverse reactions in the two groups were compared. Results The abortion rate of the observation group was higher than that of the control group, and the rate of incomplete abortion was lower than that of the control group (P <0.05). The pain degree in observation group was lower than that in control group. The operation time, gestational sac discharge time, bleeding time and recurrence time in observation group were significantly shorter than those in control group (P <0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P> 0.05). Conclusion B-mode ultrasound-guided mifepristone combined with microtubules in early pregnancy noninvasive induced abortion has a significant effect, worthy of clinical application.
