Continuous infusion therapy in haemophilia

The application of coagulation factor therapy by continuous infusion (CI) was first suggested by Brinkhous in the early 1950s [1]. The recent introduction of this mode of therapy to everyday practice was made possible after the demonstration of a good stability of most factor concentrates which were also found safe regarding potential bacterial contamination. Other developments included a better understanding of the pharmacokinetics of factors concentrates as well as the availability of a new delivery system. Continuous infusion was shown to be superior to bolus injection (Bf) in achieving a stabile haemostatic effect, in the prevention of post-operative bleeding and was found to save between 20-50% in the required factor. This mode of therapy was found effective in haemophilia A and B as well as among patients with inhibitors to FVIII and with von Willebrand disease (vWD).
