TEG/ROTEM trace. The main parameters in TEG are R, K, α-angle, MA, and LY30. The main parameters in ROTEM are CT, CFT, α-angle, MCF, and LI30. R/CT: the time from start to initial clot formation (to 2 mm amplitude), reflect coagulation function. K/CFT: the time when amplitude raises from 2 to 20 mm, reflects fibrin formation and cross-linking. α-angle: the angle between the midline and the tangent of the curve, its significance is similar to K/CFT. MA/MCF: the peak amplitude of the curve, mainly represents the platelet function. LY30/LI30: percent amplitude reduction at 30 min after MA/MCF, is a reflection of fibrinolysis
