Conventional parameters like INR although can predict mortality in these cases but don't predict risk of bleeding in these patients because they monitor only a part of coagulation cascade. These parameters assess clot formation in plasma environment while in Thromboelastography (TEG) whole blood i.e. both plasma & cellular components including platelets are assessed & a collective report of hemostatic profile of patient is available. Graph obtained using TEG gives 5 values including r time, k time, α angle, maximum amplitude & lysis at 30 min assessing different aspects. It has been widely used prior to cardiac surgery and liver transplant surgery to assess for coagulation defects.
