The effect of autologous blood salvage techniques upon bank blood usage and the cost of routine coronary revascularization.

Preservation of autologous blood during cardiac surgery may reduce the need for homologous blood transfusions. We reviewed our experience for patients undergoing primary coronary revascularization to determine the effect of the use of the Haemonetics Cell-Saver upon blood bank resources and upon the cost of operation.The quantity of homologous blood required by two groups of patients was compared. One group of 46 patients had operation prior to use of the Cell- Saver ; the other group of 31 patients was entered into Cell-Saver protocols. The mean number of homologous blood units transfused per patient fell strikingly (p < 0.0001) from 4.2 before to 0.5 after introduction of the Cell- Saver. Of the 31 patients in the Cell-Saver protocol, 71 % required no homologous blood while they received 2.5 units of autologous blood processed by the Cell-Saver. Related to this, the mean number of units prepared by typing and compatibility testing in anticipation of surgery fell from 10 units to five. The projected cost to the patient fell 23%. There were no adverse effects from the use of the Cell-Saver.We conclude that the use of the Cell-Saver is justified not only to reduce the potential risks of homologous blood transfusion, but also to reduce the strain upon blood bank resources and the patient cost of primary coronary revascularization.
