Article Synopsis
  • - The study compared newer oxygenators designed to reduce immune response during cardiopulmonary bypass (CPB) in cardiac surgery with conventional oxygenators, focusing on their effects on lymphocyte activation and apoptosis.
  • - Blood samples were taken from 20 patients (10 using each type of oxygenator) at various stages of surgery to assess lymphocyte surface markers and apoptosis through flow cytometry.
  • - Results showed significant postoperative lymphopenia, increased lymphocyte activation, and decreased apoptosis in both groups, indicating that the reduced lymphocyte count after CPB is not primarily due to cell death.
