Abstract
The aim of the study was to assess sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) of collector bag and its correlation with hemoglobin (Hb) and hematocrit (Ht) variations. This study, carried on 100 women referred for admission to labor ward of Shohada hospital in Orumeyeh City, Iran, from April to November, 2007. Serum Hb and Ht were measured after admission; a collecting bag placed under the pelvis just after birth and was weighted after delivery. Hb and Ht were again assessed at 8 hr after delivery. PPH was defined as blood loss ˃500 ml following vaginal delivery. Each 500 ml blood loss accounts for approximately a 3% change in the Ht level or a falling in Hb of 1 g/dl. With this cut off our noted Sensitivity=80%, Specificity=95. 7%, PPV= 88.9% and NPV= 91.8%. The collector bag is a rapid and precise instrument to diagnose of postpartum hemorrhage in the delivery room. It also enables a visual, quantitative and objective estimation of blood loss.
