OBJECTIVE
To compare (1) visual estimation of postpartum blood loss with estimation using a specifically designed blood collection drape and (2) the drape estimate with a measurement of blood loss by photospectrometry.
METHODS
A randomized controlled study was performed with 123 women delivered at the District Hospital, Belgaum, India. The women were randomized to visual or drape estimation of blood loss. A subsample of 10 drape estimates was compared with photospectrometry results.
RESULTS
The visual estimate of blood loss was 33% less than the drape estimate. The interclass correlation of the drape estimate to photospectrometry measurement was 0.92.
CONCLUSION
Drape estimation of blood loss is more accurate than visual estimation and may have particular utility in the developing world. Prompt detection of postpartum hemorrhage may reduce maternal morbidity and mortality in low-resource settings.
目的
比较（1）产后失血量的视觉估计与使用专门设计的采血单进行的估计，以及（2）采血单估计与通过光谱法测量失血量的结果。
方法
在印度贝尔高姆地区医院对123名分娩妇女进行了一项随机对照研究。这些妇女被随机分为通过视觉或采血单估计失血量。将10次采血单估计的子样本与光谱法结果进行比较。
结果
失血量的视觉估计比采血单估计少33%。采血单估计与光谱法测量的组内相关性为0.92。
结论
采血单估计失血量比视觉估计更准确，在发展中国家可能具有特殊用途。及时发现产后出血可降低资源匮乏地区的孕产妇发病率和死亡率。
