ΒΆFor cases in whom the blood collection drape was used and there were data for blood loss. Women with a primary diagnosis of abruption were excluded from this analysis due to the nature of the blood loss of this aetiology-pooled internal blood loss and clots captured in the drape after delivery of the placenta which should not be included in the blood loss calculation. Β§Only for women with definitive diagnoses of abruption of placenta, ruptured uterus, placenta previa, and placenta accrete. *Only for women who survived **EAO = mortality or morbidity.
