LIMITATION OF MULTIMORBIDITY IN CARDIOSUR GICAL PATIENTS WITH ACUTE-RENAL-FAILURE (ARP) BY A NEW HEMOFILTRATION DEVICE

Of a total of 2000 patients who underwent cardiac surgery with cardio- pulmonary bypass 31 patients (1.5%) had to be treated with continuous venovenous hemodiafiltration (CVVHDF) due to acute renal failure (ARF) . Treatment was established by a biocompatible membrane (type AN 69, s urface 1 m(2)) and a special therapeutic scheme. Data analysis shows a n improvement of the hemodynamic condition (MAD, CI) and a simultaneou s reduction of FiO(2) under CVVHDF. No statistically significant diffe rence in hemodynamic improvement and inotropic support was found in pa tients with or without intraaortic balloon pump (IABP). Duration of fi ltration was 16+/-8 days. No patient was conventionally dialysed. Know n lethality of ARF could be reduced from 70% to 51%. The only risk fac tor found for development of ARF was a preoperative reduced renal func tion.
