In vivo characteristics of thaw siphon cryoprecipitate compared to other factor VIII preparations
5 severe haemophiliacs were infused with cryoprecipitate prepared by the continuous thaw-siphon technique, with cryoprecipitate prepared by overnight thawing and with intermediate-purity factor VIII concentrate. All 3 preparations gave a similar mean half-life for coagulant factor VIII of approximately 10 hours. The immediate recovery of this activity was similar for the 2 cryoprecipitates, but higher for the purified concentrate.
