Patients at the intensive care unit who suffered acute renal failure with the need of continuous veno-venous hemodialysis will be investigated with continuous veno-venous hemodialysis and in a time window without continuous veno-venous hemodialysis to investigate the influence of continuous veno-venous hemodialysis on the cerebrovascular autoregulation.
The aim of the study is to characterize the influence of continuous veno-venous hemodialysis on the cerebrovascular autoregulation.
