目的了解子宫位置及胚囊大小对药物流产后阴道持续出血的影响。方法采用前瞻性的研究方法,共接纳合格妇女198例,将入选对象按子宫位置和胚囊大小分为观察组100例,对照组98例,对入选对象均进行全程随访,观察其排出后阴道出血时间和阴道出血量。结果观察组与对照组比较,药流后阴道出血时间差异有统计学意义(P<0.01),观察组阴道出血≤15 d干净者明显高于对照组。两组出血量的比较,观察组较对照组明显减少,差异有统计学意义(P<0.01)。结论子宫前屈位、后屈位阴道出血发生率明显高于正常位、前倾位、后倾位,胚囊直径越大,持续出血发生率越高。
Objective To understand the effect of uterine location and embryo sac size on persistent vaginal bleeding after medical abortion. Methods A prospective study was conducted. A total of 198 eligible women were enrolled. The subjects were divided into observation group (100 cases) and control group (98 cases) according to the location of the uterus and the size of the embryo sac. All patients were followed up for observation. Bleeding time and vaginal bleeding. Results Compared with the control group, the time of vaginal bleeding after medical abortion was statistically significant (P <0.01). The vaginal bleeding ≤15 d in the observation group was significantly higher than that in the control group. The two groups of bleeding, the observation group was significantly reduced compared with the control group, the difference was statistically significant (P <0.01). Conclusions The incidence of uterine flexion and posterior flexion vaginal bleeding was significantly higher than that of the normal, anterior and posterior, the larger the diameter of embryo sac, the higher the incidence of persistent bleeding.
