Objective To discuss clinical efficacy of taking drospirenone and ethinylestradiol tablets in preventing intrauterine adhesion after missed abortion curettage with b-ultrasonic observation.Methods216 cases of study objects provided with missed abortion curettage with b-ultrasonic observation were divided into control group with 108 cases and research group with 108 cases.Patients in control group were provided with conventional treatment after surgery, while those in research group were provided with conventional treatment and drospirenone and ethinylestradiol tablets.Two groups were compared for condition after surgery such as intrauterine adhesion in 1month after treatment, secondary pregnancy, infertility and abortion in 1 year after treatment.ResultsTime of vaginal bleeding, pelvic effusion and time of return of menses in research group were significantly lower than those in control group, with difference having statistical significance (t=6.114,t=9.481,t=9.201,P0.05).In the case of infertility rate and rate of abortion in 1 year after treatment, control group was higher than research group with difference having statistical significance (χ2=4.317,χ2=5.225,P0.05);对照组和研究组治疗1年后的不孕率、流产率进行比较,对照组明显高于研究组,差异均有统计学意义(χ2=4.317,χ2=5.225,P<0.05).结论 B超监测下稽留流产清宫术后立即服用屈螺酮炔雌醇片,能够有效预防术后宫腔粘连,并且减少流产、不孕等并发症,可根据患者实际情况进行应用.
