Reinfusate Heparin Concentrations Produced by Two Autotransfusion Systems

摘要

Objectives: Cell saver reinfusate ideally should contain low, clinically insignificant heparin concentrations. The American Association of Blood Banks has defined the clinically insignificant threshold as 0.5 IU/mL. Furthermore, there is uncertainty about the meaning of cell saver "heparin elimination rates." These concerns prompted the authors' independent investigation of reinfusate heparin concentrations of devices used in their institution. It was hypothesized that cell saver reinfusates contain clinically insignificant heparin concentrations.
