The rapid and accurate prediction of the need for massive transfusion in bleeding trauma patients remains a challenge. Various models have been proposed to anticipate massive transfusion with variable success. The current study by Mutschler and colleagues proposes four classes of shock as defined by the Shock Index and examines its ability to predict the need for massive transfusion. This model demonstrates promise as a practical tool in acute decision-making for transfusion after injury.
