5、测量的重要性；探讨产后出血相关因素及寻求有价值的高危因素评分方法。方法：回顾性研究我院2011年03月30日－2011年05月30日分娩141例孕妇的临床资料，用体积法+称重法准确测量产妇产后24小时的出血量，分析其临床表现、孕期情况、产科合并症，了解产后出血相关因素，通过logistic回归分析筛选出危险因素；并根据全身因素、人流刮宫史、妊娠期高血压疾病、前置胎盘/胎盘早剥、宫高、血红蛋白、血小板、影响凝血机制的疾病、羊水过多/多胎妊娠、妊娠合并子宫肌瘤、产程进展、分娩方式、第三产程时间、胎儿体重、胎盘残留/滞留/植入等15项相关因素制成评分表，进行评分。根据评分值与产后出血的相关性分

6、析及logistic回归分析结果评价该高危因素评分表的临床价值。结果：（1）141例孕妇测量24小时平均出血量为418.19±174.08ml，临床估算产后出血量平均为202.38±92.02ml；实际测量产后出血共27例，产后出血率为19.15%；临床估算产后出2血共4例，产后出血率为2.84%；两者产后出血率比较，χ=19.172，P＜0.05，即实际测量产后出血率高于临床估算出血率。（2）实际测量产后出血量与临床估算差值呈正相关关系，两者的Spearman相关系数r=0.858，P<0.05，即实际产后出血量越多，临床估算越不准确。(3)通过logistic单因素分析筛选出的危险因

7、素有7个，分别为巨大儿,第三产程时间,疤痕子宫,产程进展,宫高,胎盘粘连、残留、滞留等,妊娠合并子宫肌瘤。(4)在logistic多因素分析中有5个进入多因素回归模型，分别为：巨大儿（OR=10.361,95%CI2.966～36.197）；疤痕子宫（OR=6.008,95%CI1.473～24.509）；产程进展（OR=3.518,95%CI1.356～9.131）；胎盘粘连、残留、滞留等（OR=2.575,95%CI1.346～
