目的 研究在经阴道多胎妊娠减胎术中包括机械破坏、钢丝绞杀和抽吸胚芽三种不同的操作方法对手术治疗效果的影响。方法 回顾性分析 4 5例接受减胎术的 3胎以上多胎妊娠的资料 ,进行多元逐步回归分析、χ2 检验或t检验。结果 4 5例中术后流产率为 2 8 89% ;分娩孕周与手术时孕龄间的相关系数r =- 0 2 4 6 ,P =0 0 5 8,接近显著意义水平 ;χ2 检验显示以抽吸胚芽组足月产率最高而流产率最低 ,与钢丝绞杀组的流产率组间差异有显著意义 ,Pearson’χ2 =6 5 33,P <0 0 5 ;抽吸胚芽组妊娠结束时的平均孕周 (34 6 2± 7 6 0 )周为最大 ,而钢丝绞杀组 (2 7 36± 9 0 0 )周为最小 ,差异有显著意义 (P <0 0 5 )。结论 于较早期 (妊娠 7～ 8周 )采用简单的胚胎负压吸引进行经阴道多胎妊娠减胎术是较好的手术方式。
Objective To study the effects of three different operation methods including mechanical destruction, wire strangulation and aspiration germ on the operation of vaginal polyfetis pregnancy. Methods The data of 45 fetuses with more than three births undergoing fetal abortion were retrospectively analyzed. Multiple stepwise regression analysis, χ2 test or t test were performed. Results The rate of postoperative abortion in 45 cases was 2 8 89%. The correlation coefficient between gestational age at childbirth and gestational age at surgery was -0.246, P = 0 058, which was close to the significant level. The χ2 test showed that There was significant difference between abortion group and steel strangulation group in terms of full-term birth rate and abortion rate in aspirating embryo group, Pearson’2 = 6 5 33, P <0 05; at the end of pregnancy (34 6 2 ± 7 6 0) weeks was the largest, while that of wire strangulation (2 7 36 ± 9 0 0) was the smallest, with significant difference (P 0 05). Conclusion In the earlier period (7-8 weeks of gestation), it is a good surgical method to use simple embryo suction to reduce vaginal polygalactomy.
