Effect of Timing and Route of Methylprednisolone Administration During Pediatric Cardiac Surgical Procedures

Methylprednisolone administration at anesthesia induction was superior in terms of antiinflammatory action. Methylprednisolone administration in CPB-prime only a few minutes before aortic cross-clamping and cardioplegia resulted in mean troponin reductions similar to those of administration at anesthesia induction. Corticosteroids may have direct cardioprotective properties, as reported in experimental studies.
