TEG Made Easy!

Thromboelastography (TEG) is used to help guide blood product resuscitation, is situations of large blood loss, such as the operating room or in a trauma resuscitation. 

Normal (BLACK) vs Abnormal (RED) TEGs are depicted in the figure:

• Each quadrant is broken down with a black line showing the normal TEG curve overlayed with a red line that depicts the abnormal TEG curve. 

• Only one component/variable is abnormal for each quadrant (e.g. R-time in the first quadrant in the top left). 

• Each quadrant explains why the TEG is abnormal for the variable and what blood product should be given for treatment. 

The very top left also lists a quick reminder of common blood products and what factors they include. 

TEG interpretation in trauma and massive transfusion can help identify clotting factor deficiency, platelet dysfunction, fibrinogen depletion, and hyperfibrinolysis. This visual guide explains R time, K time, alpha angle, MA, and LY30 along with treatment options including FFP, cryoprecipitate, platelets, and TXA.
