Thromboelastography-guided transfusion algorithm reduces transfusions in complex cardiac surgery. – PubMed – NCBI

From the original article on TEG for  Cardiac Surgery…

The hypothesis:

Our hypothesis was that using TEG as a point-of-care test of the hemostatic system would result in prompt identification of hemostasis disorders and a reduction in transfusion requirements compared with laboratory-based testing. This would help to reduce the costs and risks associated with allogeneic transfusions. In a prospective, randomized trial, we compared bleeding and transfusion requirements in cardiac surgical patients at moderate to high risk of microvascular bleeding using a TEG-guided algorithm or standard laboratory coagulation testing.
