Although the use of renal replacement therapy (RRT) to support critically ill patients with acute kidney injury (AKI) has become routine, many of the fundamental questions regarding optimal management of RRT remain. This review summarizes current evidence regarding the timing of initiation of RRT, the selection of the specific modality of RRT, and prescription of the intensity of therapy. ⋯ There does not appear to be a difference in either mortality or recovery of kidney function associated with the various modalities of RRT. Finally, providing higher doses of RRT is not associated with improved clinical outcomes.

ReviewFluid management and use of diuretics in acute kidney injury.
Critically ill adult patients at risk for or with acute kidney injury (AKI) require careful attention to their hemodynamic status because hypotension and hypovolemia may contribute to or worsen kidney injury. Increasing evidence suggests that isotonic crystalloids should be used instead of colloids for initial expansion of intravascular volume in patients at risk for AKI or with AKI, such as those with sepsis, septic shock, or trauma. The timing and amount of volume to be administered to prevent AKI and other organ damage is still debated, but an aggressive fluid repletion in the early setting is probably beneficial. ⋯ Diuretics may prevent or treat fluid overload and may also affect kidney function. The efficacy of these procedures in critically ill AKI patients need to be confirmed with randomized controlled trials. This review focuses on early volume resuscitation, overall fluid management, and use of diuretics in critically ill adult patients at risk for or with AKI and their effect on mortality and kidney function in this setting.

This review is focused on minimizing complications and avoiding harm in peritoneal dialysis (PD) patients. Issues related to planning for PD are covered first, with emphasis on PD versus hemodialysis outcomes. ⋯ Finally, recommendations for preventing PD-related infections are provided. In conclusion, with proper catheter insertion technique, good training, and attention to detail during the tenure in PD, excellent outcomes can be obtained in a well-informed motivated patient.
