Randomized Controlled Trial Comparative Study Clinical Trial
The effect of pre-operative blood withdrawal, with or without sequestration, on allogeneic blood product requirements.
A common effect of autologous blood withdrawal before cardiopulmonary bypass (CPB) is a decrease in haematocrit (Hct) and haemoglobin (Hb) content. A refinement of this technique is autologous blood withdrawal with the sequestration of platelet rich plasma (PRP) and red blood cells (RBCs). ⋯ there were no significant differences between the study groups. This randomized trial shows that, although sequestration immediately after autologous blood withdrawal has no added value, autologous blood withdrawal in patients with a normal pre-operative Hb and Hct is simple, inexpensive and allows for autologous blood transfusion.
