中期引产不同方案选择影响因素分析

Analysis of the influencing factors of different induced labour schemes of women during the second trimester of pregnancy

目的:分析不同中期引产方案选择的影响因素。方法:回顾性分析2020年1月—2022年9月本院行孕13~27周引产临床资料210例,其中单独引产方案155例(单独组),联合引产方案55例(联合组),logistic回归分析各方案引产女性的临床特征对引产方案选择的影响。结果:单因素分析结果表明,联合组孕次(1.9±0.6次)、产次(1.8±0.5次)、孕周(1.2±0.4周)均高于单独组(0.6±0.2次、23.8±3.6次、21.3±3.7周),剖宫产史(32.4%)、胎盘异常(12.7%)和妊娠高血压病(25.4%)高于单独组(14.2%、3.9%、12.9%)(均P<0.05);引产各事件发生率两组无差异(P>0.05)。多因素回归分析表明,有剖宫产史、孕周大和孕次多是中期引产选择联合方案的因素(P<0.05)。结论:中期引产孕妇有剖宫产史、孕周和孕次较大时对中期引产方案选取影响较大,故引产前需综合评估,对上述因素孕妇可考虑联合引产方案,以提高引产效果和安全性。

Objective:To analyze the influencing factors of different induced labour schemes of women during the second trimester of pregnancy.Methods:The clinical data of 210women with induced labour during 13-27gestational weeks from January 2020to September 2022were analyzed retrospectively,including 155with single induced labour scheme in group A and 55cases with combined induced labour scheme in group B.The influence of the clinical characteristics of the women on their selection of different induced labour scheme was analyzed by logistic regression method.Results:The results of single factor analysis showed that the number of gravidity(1.9±0.6times),the parity(1.8±0.5times),and the gestational weeks(22.2±0.4weeks)of the women in group B were significantly higher than those(0.6±0.2times,23.8±3.6times,and 21.3±3.7weeks)of the women in group A.The rates of history of cesarean section(32.4%),the placental abnormality(12.7%),and the pregnancy-induced hypertension(25.4%)of the women in group B were significantly higher than those(14.2%,3.9%,and 12.9%)of the women in group A(P<0.05).There were no significant differences in the incidences of different induced labour events of the women between the two groups(P>0.05).Multivariate regression analysis showed that the history of cesarean section,the gestational weeks,and the number of pregnancies of the women were the factors affecting their selection of combined induced labour scheme(P<0.05).Conclusion:For the pregnant women with cesarean section history,with higher gestational weeks,or with greater number of pregnancies,the combined induced labour scheme should be considered for them so as to improve the effect and safety of the induced labour.
