Benefit from using recycling red blood cells in cardiovascular surgery.
OBJECTIVE
To show if blood salvage is indicated in all patients submitted to cardiovascular surgery with cardiopulmonary bypass.


METHODS
We studied 77 consecutive patients submitted to cardiac surgery with use of blood salvage and cardiopulmonary bypass from November 2010 to June 2012. The sample was divided in three groups, depending on the time of cardiopulmonary bypass. In group A, the time of cardiopulmonary bypass was smaller than 45, in group B from 45 to 90 and in group C greater than 90 minutes. We analyzed the volume of red cells recovered and infused, the pre, intra and post-operative hemoglobin, the number of packed red cells units which were transfused and hematocrit and hemoglobin blood infused.


RESULTS
The average group age was 60.44±12.09 years old, of whom 71.43% were males. The group A was formed by 5.19% of the patients, B by 81.82% and C by 12.99%. The volume of erythrocytes recovered and infused was respectively 1,360.50±511.37 ml and 339.75±87.71 ml in group A, 1,436.63±516.06 ml and 518.83±183.0 ml in B and 2,137.00±925.04 ml and 526.20±227.15 ml in C. About packed red cells transfusions, in group A 1,00±2,00 packed red cells were transfused, in B 1.27±1.85 packed red cells and in C 2.56±2.01 packed red cells. The infused blood had a hematocrit of 50.97±12.06% and hemoglobin of 19.57±8.35 g/dl.


CONCLUSIONS
That blood salvage can be used in patients submitted to cardiovascular surgery with cardiopulmonary bypass. However, it is only cost-effective in surgeries in which the time of cardiopulmonary bypass is greater than 45 minutes.
