DAMAGE TO RED BLOOD CELLS IN INTRAOPERATIVE BLOOD SALVARGE

-ANALYSIS ON RED CELL DEFORMABILITY-

Abstract

In 11 cases of cardiovascular surgery, intraoperative auto transfusion was performed using a Haemonetics Cell Saver IV R for saving intraoperative hemorrhage and remaining blood in the extracorporeal circulation system. An average of 1229.0±576.3 (mean±SD) of suspension, 45.5±12.8% of Hematocrit was obtained and the red cell deformability was measured by a modification of Reid's method. Red cell deformability was preserved well in intraoperative salvaged blood, especially in the PGE₁ group.
