Opening of the article

Thromboelastography (TEG) has been reported to be useful to detect impaired platelet function in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB), to predict excessive microvascular bleeding (EMB), guide platelet transfusion and administration of desmopressin acetate (DDAVP). As the conventional TEG has a test completion time (TCT) of greater than 30 mins we had earlier reported a modified TEG (TEG-rTT) which was activated by 0.025% of recombinant tissue thromboplastin (rTT) to shorten the TCT to 7 mins. However, TEG-rTT is known to be affected by decrease in concentrations of platelets and coagulation factors including fibrinogen.
