Background Intraoperative autologous platelet (PLT) collection as part of a multimodal blood conservation program carries a Class IIa recommendation from the Societies of Thoracic Surgeons and Cardiovascular Anesthesiologists, but achieving a suitable PLT yield limits its application. A novel, autologous, intraoperative, high-yield plateletpheresis collection program was established and retrospectively analyzed to identify potential improvements over previously reported plateletpheresis protocols. Study Design and M-ethods Targeting complex cardiothoracic surgery patients without recent anti-PLT agents, thrombocytopenia, or severe anemia, the program aimed to achieve a PLT yield of at least one standard apheresis unit (3.0 × 1011) within 60 to 90 minutes and using an automated plateletpheresis device (Trima, Terumo BCT). Anesthetized and invasively monitored patients underwent plateletpheresis via a large-bore, indwelling central line placed for the surgery. Collection-related data for quality control purposes and subsequent PLT transfusion requirements were analyzed and reported. Results Forty-two patients donated autologous PLTs between 2011 and 2012. PLT yield was 4.5 (3.9-5.0) × 1011, which significantly exceeds previously reported yields, and procedure duration was 53.2 (48.4-57.9) minutes. As anticipated, postcollection PLT count decreased from 268 (242-293) × 109 to 182 (163-201) × 10 9/L; hypocalcemia was minimized by infusion of 1 g of CaCl 2. Autologous PLT yield was inversely correlated with allogeneic PLT use, and avoidance of allogeneic PLT transfusion was increased when the autologous yield was the equivalent of 2 or more apheresis units. Conclusion High-yield, intraoperative autologous PLT collection is achievable using an automated plateletpheresis device. Initial experience shows a reduction in reliance on allogeneic PLTs for complex cardiothoracic surgery. © 2013 American Association of Blood Banks.
