The effect of cardiopulmonary bypass on platelet distribution width, red cell distribution width – standard deviation, and platelet large cell ratio

We postulate that CPB affects RDW-SD and P-LCR levels, and that there is a significant relationship between PDW, RDW-SD, and P-LCR levels and early post-CPB clinical data. We also postulate that PDW,RDW-SD, and P-LCRhave important prognostic values in predicting adverse events.
