Comparison of dialysis prescription and dose delivered in continuous renal replacement (CRRT) and intermittent hemodialysis (IHD). The ability of each modality to achieve a particular clearance is influenced by the dialysis prescription and the operational characteristics; however, it must be recognized that there may be a significant difference between the dialysis dose prescribed and that delivered. In general, IHD techniques are limited by available time, and in catabolic patients it may not be possible to achieve a desired level of solute control even by maximizing the operational characteristics.
