title: Quality of red blood cells using the Dideco Electa autotransfusion device.
abstract: The purpose of this study was to evaluate the quality of washed, concentrated red blood cells (RBCs) produced by the new Electa autotransfusion device from Cobe Cardiovascular (Dideco). Blood was collected intraoperatively in 16 patients undergoing cardiac surgery for whom routine cell savage was being used and then washed using the Electa. According to the manufacture's protocol. 125-mL bowls were used in the standard wash program. Reservoir and washed RBCs were analyzed for platelets (PLTs), leukocytes (WBCs), potassium (K+), and plasma-free hemoglobin (PFH) removal, as well as, hematocrit (Hct) and RBC recovery. The Electa cell saver produced a product with an average Hct of 58+/-5% and a RBC recovery rate of 87+/-10%. Its removal of waste products resulted in the washout of 54+/-18% WBCs, 87+/-6% PLTs, 91+/-4% K+, and 77+/-17% PFH. The Electa produces a good-quality washed RBC product that is comparable with other autotransfusion devices on the market.
