[Influence of extracorporeal circulation on renal function]

The renal function was investigated comparatively in two lots of patients with cardiovascular diseases that had been operated with and without extra-corporeal circulation. It was shown that extra-corporeal perfusion alters the renal function in an increased number of cases (28% against 17.75%). Other parenchymatous tissues have also been involved, such as the liver and the pancreas. The humoral parameters and the clinical data are discussed, which demonstrate the organic involvement following such interventions. The good results obtained stress the necessity of an energetic treatment, which should include early dialysis.
