目的探讨药物流产后应用短效避孕药屈螺酮炔雌醇片的临床价值。方法早孕要求药物流产患者171例,流产后服用屈螺酮炔雌醇片86例为观察组,不服用屈螺酮炔雌醇片85例为对照组。对照组药物流产给予米非司酮+米索前列醇口服,观察组药物流产方法同对照组,并在绒毛排出后口服屈螺酮炔雌醇片,连续3个月经周期。比较2组药物流产后阴道流血时间,行清宫术比率,第4次月经来潮前子宫内膜厚度,药物流产6个月内月经紊乱(包括周期延长或缩短、闭经)及盆腔感染发生率。结果观察组阴道流血时间[(8.25±5.48)d]较对照组[(14.23±8.57)d]明显缩短(P<0.05);观察组行清宫术比率(1.16%)、药物流产6个月内月经紊乱及盆腔感染发生率(1.16%、1.16%、1.16%)低于对照组(15.29%、9.41%、5.88%)(P<0.05);观察组流产后第4次月经来潮前子宫内膜厚度[(9.30±1.15)mm]与对照组[(10.50±1.83)mm]比较差异无统计学意义(P>0.05)。结论药物流产后及时服用短效口服避孕药屈螺酮炔雌醇片可缩短阴道流血时间,降低药物流产后清宫术比率,减少盆腔感染和月经紊乱。
Objective To investigate the clinical value of short-acting contraceptive dapsone ethinyl estradiol tablets after medical abortion. Methods In the first trimester of pregnancy, 171 cases of medical abortion were enrolled. After abortion, 86 cases of drospirenone ethinyl estradiol were taken as observation group and 85 cases of drospirenone ethinyl estradiol as control group. The control group of drug abortion given mifepristone + misoprostol orally, the observation group of drug abortion method with the control group, and oral administration of drospirenone ethinyl estradiol tablets after villus, for 3 consecutive menstrual cycles. The vaginal bleeding time, the curettage rate, the endometrial thickness before the fourth menstrual cramps, the menstrual disorder (including the prolongation or shortening of the period) and the incidence of pelvic infection within 6 months after medical abortion were compared between the two groups. Results The duration of vaginal bleeding in observation group (8.25 ± 5.48) d was significantly shorter than that in control group (14.23 ± 8.57 d) (P <0.05). The curettage rate (1.16%) in observation group was within 6 months Menstrual disorders and pelvic infections (1.16%, 1.16%, 1.16%) were lower than those in the control group (15.29%, 9.41%, 5.88% There was no significant difference in thickness [(9.30 ± 1.15) mm] compared with that in control group [(10.50 ± 1.83) mm] (P> 0.05). Conclusions The administration of short-acting oral contraceptive drospirenone ethinyl estradiol shortly after vaginal discharge can shorten the time of vaginal bleeding, reduce the rate of curettage after medical abortion, reduce pelvic infection and menstrual disorders.
