药物流产是近年来终止早孕痛苦较小、较安全的一种方法,但由于多种原因,使许多孕妇对自己的妊娠日期预算不准,故进行B超检查。 资料与方法 本文分析1998至1999年经我院超声检查并手术和病理证实的50例早期妊娠药物流产者。年龄18～40岁,初孕40例多次妊娠10例,停经天数在35～55天。尿妊娠试验阳性的孕妇,排除宫外孕、带环孕、子宫肌瘤等妇科病。 仪器采用SMZ—250AC型诊断仪,探头频率3.5MHz。受检者膀胱适度充盈,取仰卧位,行子宫纵、横、斜切面,观孕囊大小及内部结构和回声。B超检查后,常规服用药物流产药,“米非司酮”及“前列腺素”。 判断标准:1 药物流产成功:宫内未见胚囊,尿妊娠试验(一),未经刮宫,出血一周内自行停止。2.药物流产不全:宫内可见胎物残留,尿妊娠试验(-)或(+),出血量多于正常月经量,出血时间超过一周。
