Cardiopulmonary Bypass Induced Red Blood Cell Lysis

Description

Studying the dynamics of red blood cell lysis, pfH, protective proteins and organ injury, limits will be set for safe levels of pfH following the use of CPB. These results will be compared to existing laboratory-based methods for determining red blood cell damage to predict CPB assist device safety. Further, results from the studies described in this proposal will help develop therapeutic strategies to benefit patients by early detection of pfH and clearance protein levels that occur during CPB.

Conditions

Cardiopulmonary Bypass, Cardiac Surgery, Kidney Injury, Acute
