[Preventive treatment of acute renal failure in cardiac surgery].

The prevention of acute renal failure after cardiac surgery under extracorporeal circulation is possible during the pre-, per- and post-operative phases. During "ECC" the maintenance of "correct" renal perfusion is imperative, the same is also true of the post-operative period; the re-establishment of good hemodynamics is the best guarantee of maintenance of renal function. The prevention of infection is the second imperative.
