 This study investigated the association between diastolic blood pressure and massive transfusion in severe trauma patients. It was found that initial low diastolic blood pressure was an independent predictor for massive transfusion in severe trauma cases. This suggests that lower diastolic blood pressure may be associated with increased risk of massive transfusion in severe trauma patients.
