“…Previous studies have shown that nurses are inaccurate visual estimators of emesis, with wide interparticipant variability (1-3). Experience has not been shown to improve the accuracy of estimations (2,3); the same trend was found for nurses and physicians when estimating blood volume (4,5).…”

“…In three studies (14)(15)(16), a total of 486 staff members of maternity services visually estimated blood loss in simulated scenarios before and after training courses. The three uncontrolled studies (14)(15)(16) show results in the same direction as the RCT.…”

“…Underestimation of blood loss at delivery time is one the reasons of the delayed diagnosis of blood loss. Many studies indicate that assessment of post-partum blood loss following a vaginal delivery is difficult and visual estimation of blood loss is frequently inaccurate [11][12][13] . Another method for measuring postpartum blood loss is calculated of Ht and Hb variations before and after…”

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. RésuméLe but de l'étude était d'évaluer la sensibilité, la spécificité, la valeur prédictive positive (VPP), la valeur prédictive négative (VPN) du sac collecteur et sa corrélation avec les variations de l'hémoglobine (Hb) et de l'hématocrite (Ht). Cette étude a porté sur 100 femmes envoyées aux spécialistes au service de travail de l'hôpital Shohada dans la ville d'Orumeyeh, en Iran, d'avril à novembre 2007. Les taux de Hb et Ht sériques ont été mesurés après l'admission; Un sac de collecte placé sous le bassin juste après la naissance a été pondéré après l'accouchement. Hb et Ht ont de nouveau été évalués 8 heures après l'accouchement. La PPH a été définie comme une perte de sang ˃500 ml après l'accouchement vaginal. Chaque perte de sang de 500 ml représente approximativement une variation de 3% du niveau Ht ou une baisse de Hb de 1 g / dl. Avec ceci comme point minimum, nous avons noté la Sensitivité = 80%, Spécificité = 95. 7%, VPP = 88,9% et VPN = 91,8%. Le sac collecteur est un instrument rapide et précis pour diagnostiquer une hémorragie post-partum dans la salle d'accouchement. Il permet également une estimation visuelle, quantitative et objective de la perte de sang. (Afr J Reprod Health 2017; 21[1]:99-103).
