The thromobelastograph (TEG) is a photokymographic device to measure the dynamics of clot formation in vitro. The TEG graphic parameters offer clinical information regarding clotting factor function.
Graphic values from 88 open heart and liver transplantation patient TEGs were correlated to bleeding time, PT, aPTT, FIB, PLT, ACT, TT, ionized Ca++ and D-Dimer (DD) concentration. Linear and multiple regression demonstrated significant (r > .40 or r < -.4, p < .10) relationships between the following parameters.
A Basic algorithm was created to employ TEG parameters to predict the clotting function study parameter values. The TEG blood study is much less expensive than a clotting function screen, may be used to predict some of the routine clotting function study values, and whole blood coagulation information is available patient-side in 20 to thirty minutes.
Key words: thrombelastograph / cardiopulmonary bypass / coagulation
