TEG waveforms and numerical values of TEG parameters. a TEG data before administration of FVIII concentrate. The R values for both CK and CKH were prolonged, owing to FVIII deficiency. b TEG data after FVIII replacement. The R values for both CK and CKH became normal. c TEG data after heparin administration. The R value for CK was significantly prolonged, owing to the effect of heparin, although that for CKH was also prolonged by 0.7 min. d TEG data after protamine administration. The R values for both CK and CKH were normal. All TEG parameters showed normal values, indicating adequate heparin reversal and preserved levels of coagulation factors including FVIII. Reference ranges for each parameter are indicated within brackets. FVIII, factor VIII; MA, maximum amplitude; R, reaction time; TEG, thromboelastography; NA, not applicable
