How shall we transfuse Hippolyta?

The US Department of Defense recently made the decision to open direct ground combat roles to women. Blood product transfusion is an essential component of the US Military guidelines for tactical combat casualty care and damage control resuscitation, but blood transfusion carries with it the specific side effect of alloimmunization-a uniquely significant side effect for young women who may desire subsequent pregnancies. Presently to be considered are the changes that may need to be made to blood transfusion in the setting of battlefield medicine to optimally care for combat-injured women, as a majority of the existing data regarding the risks of transfusion in the trauma setting involve predominantly men. This article delves into the possibility of a new cohort of women at risk for hemolytic disease of the fetus and newborn, the need for women's health professionals to appropriately counsel women considering serving in direct ground combat roles about this specific risk, and the appropriate steps that should be considered to provide these women optimal medical care.
