Background:
Patient Blood Management (PBM) promotes optimal patient outcomes by preserving autologous blood and minimizing allogeneic transfusions. SAME™ (i-SEP) is an innovative intraoperative cell salvage device using flow filtration to recover both red blood cells and functional platelets, unlike traditional centrifugal systems.
Methods:
Clinical data were derived from the multicentric i-TRANSEP first-in-human study and the SEPIA registry, including patients undergoing high-hemorrhagic-risk cardiac surgery. A comparative analysis was conducted between flow filtration (SAME™) and centrifugation (Xtra™) regarding platelet preservation, transfusion requirements, and postoperative biological evolution. A monocentric observational cohort (CHU Nantes, 2021–2024, n = 293) evaluated perioperative platelet count variation as the primary endpoint, with secondary endpoints including transfusions and postoperative complications.
Results:
Flow filtration demonstrated efficient recovery of viable, non-activated platelets, maintaining their activation capacity. In the SEPIA registry subset of high-risk cardiac surgeries, SAME™ significantly reduced allogeneic transfusions across blood components (−27% to −44%, p < 0.05). In the Nantes cohort, patients treated with filtration showed higher postoperative platelet counts and a trend toward reduced transfusion needs compared to centrifugation (RBC, plasma, platelets). No safety signal or increase in adverse events was observed.
Conclusion:
Intraoperative cell salvage using flow filtration appears to better preserve platelet integrity and functionality compared with centrifugation, leading to decreased transfusion exposure and supporting PBM strategies in high-risk cardiac surgery. These findings encourage further prospective multicentric studies to confirm clinical benefits and cost-effectiveness.
