Abstract
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.
Conclusion
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.
