Thromboelastogram (TEG) has been extensively studied in trauma and surgical patients, but has not been well studied in nontraumatic bleeding, nor has its use been well evaluated in the emergency department.

This study suggests that patients with nontraumatic hemorrhage may benefit from TEG-guided resuscitation and do not always need rapid transfusion of blood products.

This can limit transfusion-related risks for susceptible populations.

It also allows for the conservation of valuable resources through data-driven allocation of blood products to patients who are most likely to benefit from them.

TEG-guided resuscitation may be difficult in the emergency department due to concern for treatment delays but obtaining TEGs early in the hospital course may assist the admitting team’s work-up and treatment.
