In order to ensure that the instruments were in good
working order it was determined that the date of the last
maintenance check was within 6 months of running the
test.
Since PRP is more stable during storage and transportation, this was determined to be the sample of
choice. A pool of normal as well as FVIII deficient
plasma was provided by Center for Hemophilia and

counterbalanced or at least questioned [2]. Screening for coagulation abnormalities and application of
hemostatic interventions based on classical coagulation tests such as prothrombin time (PT) and
activated partial thromboplastin time (aPTT) are of
limited value in perioperative and acutely ill
patients [3]. Whole blood testing by thromboelastography may offer advantages in these clinical
settings. Originally invented in 1948 [4], its concept
predates the introduction of the aPTT test in plasma
[5]. Recent methodological improvements of
thromboelastography have widely expanded its
use from preclinical hemostasis research to pointof-care use in the emergency and the operation
room. Two commercially available devices are
TEG (Thromboelastograph; Haemoscope/Haemonetics, Niles, Ill) and ROTEM (Rotation Thromboelastometry; TEM International, Munich,

Germany). The TEG system has been available
for many years in the United States, whereas the
ROTEM system has been recently approved by the
Food and Drug Administration for clinical use. In
this review, the term thromboelastography will be
used to describe general principles of the common
technology, but the differences between the 2

Thrombin generation measurements with 1 pM tissue
factor trigger in the absence of thrombomodulin
Thrombin generation measurements in the absence of
thrombomodulin are presented in Table 1(B), and the
ETP and peak height are depicted in Figure 2 (panels A
and B, respectively; solid lines). Correlations of the
thrombin generation parameters with FVIII levels are
presented in Table 2. The effects of FVIII administration
and the addition of thrombomodulin on the thrombin
generation curve are depicted in Figure 3. The lag time
showed no significant changes upon FVIII administration
and the lag time and FVIII levels were not correlated.
The ETP increased significantly after FVIII infusion to
a peak value of 114.5% after 15 min. Forty-eight hours
after FVIII administration, the ETP returned to the baseline value of 40.0%. FVIII levels correlated with the ETP
in the group of patients as a whole (R=0.79, p<0.0001).
However, when data were analyzed per individual
patient, correlations were markedly higher. Despite
these correlations, there was a wide range of ETP at
higher FVIII levels. Prior to FVIII administration, the peak
height was relatively low compared to the ETP (24.0 vs.
40.0%), but became greater after 15 min: 126.0%. The

peak height returned to baseline by 48 hours (29.0%).
Similar to the ETP, the peak height correlated with FVIII
levels in the whole group of patients (R=0.79, p<0.0001),
although stronger correlations were found in individual
patients. Administration of FVIII significantly shortened
the time to peak (from 16.9 to 10.3 min after 15 min).
The time to peak was the only thrombin generation
parameter still significantly decreased after 48 hours
(15.2 vs. 16.9 min at baseline). The time to peak was
inversely correlated with FVIII levels (R=-0.75,
p<0.0001). In contrast to the ETP and peak height, the
time to peak values were within a narrow range across
all FVIII levels.
The slope was calculated from non-normalized peak
height data, a method that yields comparable data to the
slope calculated from normalized peak height data
(R=0.997, p<0.0001, data not shown). The slope increased
significantly upon FVIII infusion, reaching a peak of 11.0
nM/min after 1 hour. After 48 hours the slope returned
to baseline: 1.6 nM/min. The slope correlated with FVIII
levels in the group of patients as a whole (R=0.74,
p<0.0001).The ETP, peak height and slope were strongly
correlated in all patients.

This WP makes the following recommendations for the
use of TEG/ROTEM as it relates to the clinical manageTromboelastografi
vid hemofili-rekommendationer
ment and clinical trials in patients with hemophilia:
1 Investigators and treaters may use either device (TEG
or ROTEM).
2 For clinical care, we recommend the use of intrinsic
pathway activation with kaolin (TEG) or INTEM (ROTEM).
3 For clinical trials, we recommend intrinsic pathway
activation as the primary method. Extrinsic pathway
activation can be used in an exploratory fashion,
although we cannot endorse any specific method.
