ABSTRACT

Intermittent HD continues to be the preferred treatment of CIN-related ARF. However, no clear evidence of its superiority over other kinds of RRT has ever been demonstrated. In particular, a form of RRT, simpler than HD, such as HF, permits effective fluid and solute removal with greater fluid volume control, and, from the logistic standpoint, without requiring the availability of trained dialysis personnel. Moreover, HF offers better cardiovascular stability in critically ill patients than does conventional intermittent HD, and this represents a clear advantage, especially in the treatment of ARF in patients with associated cardiac insufficiency.40,41 Until now, controlled studies have not shown a definite advantage of HF, in comparison with HD, in patient survival.42-45 Furthermore, the selection of the best RRT modality may differ in different clinical situations, and no comparative studies have ever been performed in order to investigate the possible superiority of HF over HD in ARF complicating procedural cardiovascular procedures.
