TEG acceptable

advertisement
Correlation Acceptable: Yes
Criteria for acceptability: The utility of the TEG is its ability to help guide transfusion therapy, especially
in the settings of trauma and surgery. Based on this, if the TEGs run at both Cincinnati Children's
Hospital and University of Cincinnati would, upon pathologist review, trigger a transfusion, then they
correlate since both offer clinically actionable data. If both TEGs appear to show an adequate coagulable
state with no hyperfibrinolysis, then they correlate as well. A lack of correlation, for example, would be
if only one TEG shows a hypocoaglable state that could be improved with transfusion of blood products.
Hypocoagulable: Low maximum clot firmness/amplitude would warrant a transfusion of platelets and/or
cryoprecipitate. Prolonged clotting time, outside the defined normal range, would warrant transfusion
of fresh frozen plasma or four factor concentrates.
Hypercoagulable: Maximum clot firmness/amplitude that is greater than the established normal range.
Hyperfibrinloysis: Greater than 15% clot lysis.
