Criteria of Talving et al for Coagulopathy Associated with Traumatic Brain Injury (TBI)

Description

Talving et al listed criteria for the diagnosis of coagulopathy secondary to traumatic brain injury (TBI). Necrotic brain tissue acts as a tissue thromboplastin that can trigger coagulation. The authors are from the University of Southern California in Los Angeles.


 

Criteria for coagulopathy secondary to traumatic brain injury - both of the following:

(1) severe traumatic brain injury (head AIS score >= 3)

(2) one or more of the following not due to another cause:

(2a) platelet count < 100,000 per µL

(2b) elevated international normalized ratio or INR (= elevated prothrombin time)

(2c) elevated aPTT

 

where:

• The presence of DIC would also be a defining coagulation finding.
