Thromboelastogram-Guided Transfusion Therapy Reduces Blood-Component Transfusion and Improves Coagulation Function during Orthopedic Surgery

Table 4

Changes of coagulation indexes on the TEG before and after transfusion.

Time	time (min)	time (min)	MA value (mm)	CI	Angle (°)
Before transfusion
After transfusion	^b	^b	^b	^b	^b

time: time to reach a certain clot strength; time: coagulation reaction time; angle (α): clot formation rate; MA value: maximum amplitude; CIn: coagulation index. The letter of b suggests compared to pretransfusion.
