massive transfusion protocol
Also written as: MTP — massive transfusion protocol
A standardized approach for rapid delivery of blood products in patients with life-threatening hemorrhage.
Full Definition
A massive transfusion protocol (MTP) is an institutional algorithm that enables immediate access to large volumes of blood products for patients with severe bleeding. It typically involves a 1:1:1 ratio of packed red blood cells, fresh frozen plasma, and platelets to mimic whole blood composition. The protocol is activated when a patient is expected to receive 10 or more units of packed red blood cells within 24 hours, or has specific clinical triggers indicating massive blood loss.
Usage
Usage note: Capitalize when referring to a specific institutional protocol. 'Protocol' is essential - avoid shortening to just 'massive transfusion' in formal contexts.
