Abstract
目的 探讨产后恶露变化规律,绘制恶露变化模式图.方法2002年7月至12月在我院分娩的产妇,剖宫产191例,阴道分娩187例.用子宫出血记录表通过面积法记录格子型卫生巾上血染格子数,测量产后24 h后至恶露干净时的每日出血量及恶露持续天数.产妇统一于产后42 d回院随访,回收子宫出血记录表.结果恶露持续时间阴道分娩组为(33.9±12.0)d,剖宫产组(39.6±13.1)d;95%CI分别为10~57 d和14~65 d,差异有统计学意义(P<0.05).剖宫产组波动性恶露病例(103例,66.5%)明显多于阴道分娩组(28例,19.9%,P<0.01). 结论剖宫产组恶露时间长于阴道分娩组,95%CI为阴道分娩组10~57 d,剖宫产组14~65 d.产后恶露具有波动性,尤其是剖宫产组。
