Citrated Kaolin Thrombelastography (CK-TEG) Parameters by Massive Transfusion Status

CK-TEG Parameter	No Massive Transfusion	Massive Transfusion	p-value
R-Time (min)	4.4 (3.6–5.4)	4.9 (4.3–6.1)	0.0084
Alpha angle (degrees)	70.3 (66.7–73.5)	66.2 (59.8–69.9)	<0.0001
MA (mm)	65.45 (61.6–68.9)	57 (48–65.5)	<0.0001
LY30 (%)	1.2 (0.3–2.4)	1.8 (0.3–19.7)	0.0012

Data are presented as median and interquartile range. MT is defined as >10 units of RBCs or death in first 6 hours from injury. R-Time=reaction time, MA=maximum amplitude, LY30=fibrinolysis 30 minutes after achieving MA.
