Connecticut’s Saint Francis Hospital expanded its prehospital whole blood transfusion program to include a fourth EMS agency, marking significant progress in bleeding control and trauma care. EMS clinicians in participating systems now carry whole blood—containing red cells, plasma and clotting factors—allowing them to begin lifesaving transfusions on scene or en route, rather than waiting for hospital arrival. Early blood replacement has been linked with improved survival in severely hemorrhaging patients and represents an operational shift in field resuscitation protocols and training requirements for advanced bleeding management.
