Effects of Hemofiltration and Mannitol Treatment on Cardiopulmonary-Bypass Induced Immunosuppression

Summary

After cardiac surgery with cardiopulmonar bypass, the LPS-stimulated cytokine response has been previously shown to be depressed. Therefore, in this trial the hypothesis was tested, whether simple immunomodulting interventions like the i.v. adminstration of mannitol of hemofiltration during cardipulmonary bypass can attenuate this immunosuppressing effect.
