超声监测在预防药物流产后阴道出血中的作用

Effect of Ultrasound Monitoring in the Prevention of Vaginal Bleeding after Medical Abortion

目的:探讨超声检测在预防药物流产后阴道出血的意义。方法:选取438例符合入组条件的临床诊断宫内早孕且要求终止妊娠的妇女。药物流产前B超测得孕囊直径,并根据宫颈与宫体的角度分为5组,即子宫水平位、子宫前倾位、子宫后倾位、子宫前屈位和子宫后屈位。各组给药方法相同,观察药物流产效果。结果:流产前孕囊直径大小与药物流产后阴道出血时间相关;子宫前屈位及后屈位者药物完全流产率低,与其他组比较有显著性差异(P<0.01)。结论:药物流产前通过B超检测的孕囊直径及子宫位置对评价药物流产效果及流产后阴道出血时间有相关性。

Objective： To explore the significance of ultrasound monitoring in the prevention of vaginal bleeding after medical abortion. Methods： 438 women with early pregnancy who wanted to terminate pregnancy by medicine were randomly divided into 5 groups according to the uterus position which were normal position of uterus, uterine anteversion position, uterine retroversion position, uterine antefioxion position and uterine retroflexion position. The diameter of gestational sac was measured by ultrasound before medical abortion. The same medicine was administered in 5 groups and the effect of abortion was observed. Results ：The gestational sac diameter were correlated with vaginal bleeding days. The rates of complete abortion of uterine antefioxion and uterine retroflexion position were significantly lower than that of the other groups（P〈0.01）. Conclusion： The diameter of gestational sac measured by ultrasound before medical abortion and uterus position shows the positive effect for the evaluation of the effect of medical abortion and vaginal bleeding days after medical abortion.
