摘要目的：观察戊酸雌二醇和屈螺酮在稽留流产清宫术前后应用的临床疗效。方法选择稽留流产并行清宫术的患者160例，采用数字表法随机分为观察组和对照组，两组患者在清宫术前1 h 均口服米索前列醇400μg，后充盈膀胱，在 B 超引导下行清宫术，术后常规用抗生素3 d。观察组清宫术前3 d 予戊酸雌二醇4 mg 口服，每天2次，连服3 d；清宫术后当天起予屈螺酮口服，每晚1片，连用3个周期。对照组清宫术前后不予戊酸雌二醇和屈螺酮。观察两组手术时间、术中出血量、术后阴道流血时间及流血量、首次月经复潮时间、子宫内膜修复及术后并发症发生情况。结果对照组手术时间、术中出血量、首次月经复潮时间、子宫内膜厚度、术后并发症发生率分别为（6．05±0．49）min、（50．88±9．18）mL、（36．51±1．95）d、（4．08±0．56）mm、15．0％，观察组分别为（4．46±0．45）min、（35．63±8．24）mL、（29．28±1．57）d、（6．11±0．76）mm、3．8％，两组手术时间、术中出血量﹑首次月经复潮时间、子宫内膜厚度、术后并发症发生率差异均有统计学意义（t ＝－11．264、－16．643、－24．93、19．151，χ2＝5．959，均 P ＜0．05）。结论稽留流产清宫术前后给予戊酸雌二醇和屈螺酮，能有效改善清宫术的近远期并发症，提高清宫术的临床疗效。

abstractsObjective To observe the clinical effects of estradiol valerate and drospirenone applying in missed abortion and curettage before and after operation.Methods 160 patients with missed abortion parallel curet-tage were chosen,who were randomly divided into the observation group and control group by the number table meth-od.Two groups of patients were oral misoprostol 400 g before uterine curettage 1 h,and then were treated with ultra-sonic curettage after filling the bladder and postoperative routine use of antibiotics for 3 D.3 D before the curettage, observation group were treated with oral estradiol valerate 4 mg for 3 D,2times a day..After curettage of the day, drospirenone orally was given for 1 tablet every night,used in conjunction a cycle for 3weeks.The control group before and after curettage were given without estradiol valerate and drospirenone.Operation time,bleeding volume,postopera-tive bleeding time and bleeding volume,the time of the first menstrual cycle,endometrial repair and postoperative complications were observed in the two groups.Results In the control group,operation time,intraoperative bleeding volume,for the first time the resumption of menstruation tide time,endometrial thickness,postoperative complication rate were (6.05 ±0.49)min,(50.88 ±9.18)mL,(36.51 ±1.95)d,(4.08 ±0.56)mm and 15.0%;the data of the observation group were (4.46 ±0.45)min,(35.63 ±8.24)mL,of (29.28 ±1.57)d,(6.11 ±0.76)mm and 3.8%.The operation time,intraoperative bleeding volume,for the first time the resumption of menstruation tide time, endometrial thickness,postoperative complication rate differences of the two groups were statistically significant(t =-11.264,-16.643,-24.93,19.151,χ2 =5.959,all P <0.05).Conclusion Giving estradiol valerate and flexor buspirone before and after missed abortion and curettage,can effectively improve the short -term and long -term complications of uterine curettage,and improve the clinical efficacy of dilatation and curettage.
