“…r-hirudin has been shown to provide predictable dosedependent anticoagulation in a canine model of CPB, with lower levels of perioperative blood loss than UFH [15]. In a separate study employing the same model, fibrin deposites in the CPB filter were higher in the r-hirudin-treated animals [57,58].…”

“…This problem of limited sensitivity of aPTT for higher levels of hirudin has been verified by many investigators. 14,15,28 This is in contrast to heparin. It is well-known that more pronounced prolongations of aPTT can be measured under heparin therapy than can be measured under an equally effective hirudin regimen.…”

“…24,25,28 These investigators concluded that the ACT ratio is not suitable for monitoring hirudin therapy, because hirudin plasma levels do not correlate with the ACT prolongation.…”

“…1) [27]. Dieses in mehreren Studien nachgewiesene Problem ist unter anderem auf die großen interindividuellen Schwankungen im Ansprechen auf das Medikament zurückzuführen [14,15,28] 26]. Da oftmals höhere Spiegel auftreten, kann diese Axt der Bestimmung und ihre Form der Auswertung nicht als problemgerecht angesehen werden.…”

“…Diese sehr einfach durchzuführende Methode wurde im Rahmen kardiochirurgischer Eingriffe mit extrakorporaler Zirkulation untersucht [24,25,28]. Übereinstimmend kommen die Untersucher zu dem Schluß, daß die ACT-Ratio wegen der sehr schlechten Beziehung zu den Hirudinplasmaspiegeln für das Monitoring ungeeignet ist, obwohl Plasmakonzentrationen bis 6 mg/1 erfasst werden können.…”
