Abstract
Comparison of Biopump and roller pump.
The qualitative and quantitative studies of platelet were performed to evaluate the difference of the effects of centrifugal pump and roller pump on platelet during short-term CPB with membrane oxygenator.
There was no significant difference between the two pump systems in regard to the levels of platelet loss and increase rate of βTG and PF 4.
It is considered that the degree of prebypass platelet aggregation of each patient rather contributes to the degree of the consumption of platelet during bypass.
