目的:分析导致药物流产失败的多种因素,提高完全流产率。方法:对绍兴市计划生育宣传技术指导站收治的非病理性原因要求药物终止妊娠的1 284例早孕妇女,从孕囊大小、剖宫产史、流产次数、子宫位置及有无慢性盆腔炎性疾病五方面分析与药物流产失败率的关系。结果:孕囊直径≥20mm者流产失败率明显高于<20mm者,差异有统计学意义(P<0.01);有剖宫产史者流产失败率明显高于无剖宫产史者,差异有统计学意义(P<0.01);流产次数≥3次者流产失败率明显高于<3者,差异有统计学意义(P<0.01);后倾后屈位子宫者药物流产失败率明显高于平前位子宫者,差异有统计学意义(P<0.01);有慢性盆腔炎性疾病者药物流产失败率明显高于无慢性盆腔炎性疾病者,差异有统计学意义(P<0.01)。结论:药物流产失败率与孕囊大小、剖宫产史、流产次数、子宫位置及有无慢性盆腔炎性疾病有关。
OBJECTIVE: To analyze the various factors leading to the failure of medical abortion and to improve the rate of complete abortion. Methods: A total of 1 284 pregnant women with non-pathological reasons for non-pathological reasons for termination of pregnancy were enrolled in this study. The gestational sac size, cesarean section history, abortion frequency, uterine position and the presence or absence of chronic pelvic inflammatory disease Relationship between five aspects of disease and failure rate of medical abortion. Results: The failure rate of gestational sac≥20mm was significantly higher than <20mm, the difference was statistically significant (P <0.01). The failure rate of abortion with cesarean section was significantly higher than that without cesarean section, the difference was (P0.01) .The failure rate of miscarriage≥3 was significantly higher than <3, the difference was statistically significant (P0.01) .The failure rate of medical abortion after posterior levitation flexion was significantly higher than that of the control (P <0.01). The rate of medical abortion failure in patients with chronic pelvic inflammatory disease was significantly higher than those without chronic pelvic inflammatory disease, the difference was statistically significant (P <0.01). Conclusion: The abortion rate of abortion is related to the gestational sac size, history of cesarean section, the number of miscarriage, uterine position and the presence or absence of chronic pelvic inflammatory disease.
