Evaluation by obstetric care providers of simulated postpartum blood loss using a collector bag: a French prospective study

AbstractObjective: Postpartum hemorrhage (PPH) is one of the most common causes of mortality in obstetrics worldwide. Accuracy in the estimated blood loss is a priority in determining appropriate treatment. The aim of this study was to evaluate the accuracy of estimating blood loss by obstetrics care providers during simulated training sessions.Method: A prospective study occurred in 2013 in a maternity ward at a teaching hospital. Simulation training sessions recreated a vaginal delivery in which six different scenarios were presented and proposed to each participant for them to estimate the blood loss (from 350 ml to 2500 ml) while using a collector bag graduated every 100 ml from 0 ml to 1500 ml. The primary endpoint was to determine if participants could accurately evaluate blood loss within a 20% error margin.Results: About 90.7% of the medical staff participated. Ninety-three to 98% of the participants were accurate in their answer depending on which volume they had to estimate. For the lowest volum...
