“…[20][21][22] Regardless of mechanism, this female-specific hypercoagulability persists after injury 9,10,23 and confers decreased morbidity in the form of less blood transfusions, traumatic hemorrhage progression, intraoperative blood loss, 9,24-28 and a survival benefit. 9,29 In a secondary analysis of the Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) trial, McCrum et al found that after anatomic hemostasis, females received lower volumes of all blood products, with a 38% reduction in plasma, 49% reduction in platelets, and 49% reduction in red blood cell volumes. 30 Males ultimately receive relatively more transfusions, 31 which translates into higher rates of transfusionrelated complications, such as ventilator-associated pneumonia, organ failure, acute respiratory distress syndrome, and longer intensive care unit and hospital length of stay.…”
