目的:探讨稽留流产清宫术后即时应用屈螺酮炔雌醇片的临床意义。方法:随机选择稽留流产并行清宫术的自愿患者200例,随机分成观察组和对照组,两组患者均在清宫术前2 h阴道用卡前列甲酯栓1 mg,术后常规应用抗生素3天,研究组在清宫术后立即给予优思明,每天1片,连续3个周期,对照组不给药。随访观察两组术后首次月经复潮时间和月经量,阴道分泌物,B超检查有无宫腔积血,用药不良反应及停药后发生复发稽留流产率。结果:观察组稽留流产清宫术后阴道分泌物减少,阴道出血量少于对照组,阴道出血时间及月经复潮时间短于对照组,停药后的复发稽留流产率优于对照组(P<0.05)。结论:稽留流产清宫术后立即服用屈螺酮炔雌醇片可促进子宫内膜修复,恢复正常月经周期,停药后复发稽留流产率降低,是一种值得推广的安全、有效的方法。 Objective: To investigate the clinical significance of applying drospirenone ethinyl estradiol tablets immediately after abortion.

Follow-up observation of the first postoperative menstrual flow tide time and menstrual flow, vaginal secretions, B-ultrasound with or without uterine hemorrhage, adverse drug reactions and recurrent missed abortion rate after withdrawal. Results: In the observation group, vaginal secretions decreased, the amount of vaginal bleeding was less than that of the control group, vaginal bleeding time and menstrual resurgence time were shorter than those of the control group, and the recurrence rate of missed abortion was better than that of the control group (P < 0.05). CONCLUSIONS: Abortion abortion with withdrawal of drospirenone ethinyl estradiol immediately after abortion can promote endometrial repair and restore normal menstrual cycle.
