Limited transthoracic echocardiogram (LTTE) represents an attractive alternative to formal transthoracic echocardiogram (TTE), because it does not require an echocardiogram machine. Our hypothesis is that trauma attendings can learn LTTE effectively with minimal training. ⋯ Trauma attendings can successfully learn LTTE with minimal training and use the technique as a resuscitation tool in the hypotensive patient.

Comparative Study Clinical Trial
Clotting factor deficiency in early trauma-associated coagulopathy.
Coagulopathic bleeding is a leading cause of in-hospital death after injury. A recently proposed transfusion strategy calls for early and aggressive frozen plasma transfusion to bleeding trauma patients, thus addressing trauma-associated coagulopathy (TAC) by transfusing clotting factors (CFs). This strategy may dramatically improve survival of bleeding trauma patients. However, other studies suggest that early TAC occurs by protein C activation and is independent of CF deficiency. This study investigated whether CF deficiency is associated with early TAC. ⋯ Twenty percent of all severely injured patients had critical CF deficiency on admission, particularly of factor V. The observed factor V deficit aligns with current understanding of the mechanisms underlying early TAC. Critical deficiency of factor V impairs thrombin generation and profoundly affects hemostasis.
