目的探讨药物流产后阴道出血清宫的时机选择。方法选择药物流产后阴道出血≥10d,腹部B超示宫腔内膜未见异常回声者,愿意接受清宫术的74例患者作为研究组,另外将同样条件不愿意接受清宫术的74例患者作为对照组,观察两组的治疗结局。结果研究组阴道出血量、流血时间、尿人绒毛膜促性腺激素(human chorionic gonadotrophin,HCG)转阴时间、月经复潮时间及子宫内膜炎发生率明显低于对照组(P<0.05)。两组不全流产率差异无显著性(P>0.05)。结论药物流产后出血时间≥10d者应尽早行清宫术,可减少药物流产并发症,有助于患者的迅速恢复。 Objective To explore the timing of vaginal bleeding after drug abortion. Methods Select vaginal bleeding after drug abortion ≥ 10d, abdomen B-ultrasound showed no abnormal echo of the uterine lining, who were willing to accept the curettage of the 74 patients as the study group, the other under the same conditions are not willing to accept curettage of the 74 patients as Control group, observe the treatment outcome of the two groups. Results The vaginal bleeding volume, bleeding time, HCG negative time, menstruation recuperation time and the incidence of endometritis in study group were significantly lower than those in control group (P <0.05). Two groups of incomplete abortion rate was no significant difference (P> 0.05). Conclusion bleeding after medical abortion ≥ 10d should curettage as soon as possible to reduce the complications of medical abortion and help patients recover quickly.
