ECMO survival patients
In the investigators previous study (Ann Thorac Surg 2002, 73: 538-545), the investigators knew that for those adult patients receiving ECMO support for post-cardiotomy cardiogenic shock, 1/3 of them would survive to discharge, 1/3 could not be weaned from ECMO and died on the ECMO support, and 1/3 could be weaned from ECMO support, but finally died of multiple organ failure. However, by clinical observation in the first few days of ECMO support, it would be very difficult to predict the outcome of a specified individual patient. Therefore, the investigators usually wait for four to six days to know whether the ECMO treatment is successful or not. If the investigators could predict the result one or two days earlier, this would give physicians enough time to make medical decision. Therefore, the early parameters that could be used to predict the outcome of ECMO treatment would be very valuable. The investigators also found that despite obscure clinical presentation, there was a significant difference in serum cytokines' concentration on the 3rd day of ECMO support between "ECMO successful" and "ECMO failure" patients.
In this study, the investigators will further investigate leukocyte free radical activity, oxidation damage marker (8-OHdG concentration) in serum, whole blood glutathione peroxidase activity for antioxidation, serum IL-6, IL-12, IL-8, IL-10, transforming growth factor-β and other biochemical concentrations and immune cellular changes during the period of ECMO treatment. Patient's blood samples before and 2, 6, 12, 24, 48, 72 hours after ECMO support treatment, at ECMO removal and ICU discharge will be collected and used for the study. The measured factors and the final outcome will be compared. The investigators hope to find early factors change during ECMO treatment among biochemical, immunological and clinical parameters.
