Retrograde autologous priming method reduces plasma free hemoglobin level in aortic surgery
Background: Although conventional cardiopulmonary bypass (cCPB) is still the most widely used method in open heart surgery, methods such as retrograde autologous priming (RAP) are increasingly popular in terms of limiting hemodilution.Our hypothesis is that the use of the RAP method in aortic surgery may result in a limitation of hemodilution and a
