目的探讨药物流产效果与B超监测的关系。方法给予接受药物流产患者,在药物流产前及用药后第七天均行B超监测。根据B超测定孕囊的结果,将患者分为两组。A组100例,孕龄30~40d,孕囊直径7~12mm;B组98例,孕龄41~49d,孕囊直径12~20mm。给予两组患者均服用米非司酮及米索前列醇终止妊娠。结果 A组完全流产率(81.0%)明显高于B组(70.4%);子宫前倾患者的流产率明显高于其他子宫位置的患者。结论进行药物流产时,应尽量考虑患者B超监测宫内妊娠、妊娠部位、孕囊直径等信息,给予合理的流产建议。
Objective To explore the relationship between abortion outcome and B-monitoring. Methods Patients undergoing medical abortion were subjected to B-ultrasound monitoring before drug abortion and on the seventh day after administration. According to the results of determination of gestational sac B ultrasound, the patients were divided into two groups. A group of 100 patients, gestational age 30 ~ 40d, gestational sac diameter 7 ~ 12mm; B group 98 cases, gestational age 41 ~ 49d, gestational sac diameter 12 ~ 20mm. Both groups were given mifepristone and misoprostol to terminate the pregnancy. Results The complete abortion rate (81.0%) in group A was significantly higher than that in group B (70.4%). The rate of abortion in patients with uterine anterior incisors was significantly higher than that in other uterine positions. Conclusions During medical abortion, we should try to consider the information of intrauterine pregnancy, pregnancy site, gestational sac diameter and so on, and give reasonable abortion recommendations.
