剖宫产产后出血的高危因素分析

目的:分析剖宫产产后出血的产前高危因素,为预防产后出血提供依据。方法:将暨南大学附属第一医院2002年1月～2008年12月间住院行剖宫产术终止妊娠发生产后出血的产妇100例作为病例组,选择同期非出血剖宫产产妇100例作为对照组。采用回顾性病例对照研究设计方法,对比两组产后出血相关危险因素的暴露率及结局。结果:高龄、孕次≥3次、经产妇、流产≥2次、文化程度低、妊娠期高血压疾病、中重度贫血、红细胞3.50×109/L、妊娠合并子宫肌瘤(≥3cm)、前置胎盘、血小板100×109/L、胎盘早剥、宫缩抑制剂的使用、多胎均为产后出血的高危因素。经多因素Logistic回归分析,产前应用宫缩抑制剂、经产妇、妊娠合并子宫肌瘤(≥3 cm)、前置胎盘、双胎和文化程度低是剖宫产产后出血的独立高危因素。结论:产前使用宫缩抑制剂者应加强产后出血的防治,妊娠合并子宫肌瘤直径≥3 cm者,不建议在剖宫产术中常规实施子宫肌瘤剔除术。
