ReviewContinuous renal replacement therapy: individualization of the prescription.
Continuous renal replacement therapy (CRRT) is now the mainstay of renal organ support in the critically ill. As our understanding of CRRT delivery and its impact on patient outcomes improves there is a focus on researching the potential benefits of tailored, patient-specific treatments to meet dynamic needs. ⋯ Clinicians have limited evidence to individualize the prescription of CRRT. To develop this, we need to understand the requirements for renal support for individual patients, such as electrolyte imbalance, fluid overload or clearance of systemic inflammatory mediators to allow us to target these abnormalities in appropriately designed randomized trials.

ReviewRenal replacement therapy in the ICU: intermittent hemodialysis, sustained low-efficiency dialysis or continuous renal replacement therapy?
Severe acute kidney injury in the ICU setting often requires renal replacement therapy (RRT). Intermittent hemodialysis (IHD), hybrid forms of RRT such as sustained low-efficiency dialysis (SLED), as well as continuous renal replacement therapy (CRRT) are the three common modalities of extracorporeal RRT used in the adult ICU setting in developed countries. This review summarizes recently published data regarding comparisons of these three RRT modalities on clinical outcomes (e.g., mortality and recovery of renal function) in severe acute kidney injury (AKI) patients. ⋯ There is lack of solid evidence showing superiority of any mode of RRT in patients with severe AKI in terms of patient survival. However, based on observational data, IHD treatment of AKI may delay renal recovery. Patients' hemodynamic status, coexisting medical conditions, local expertise, and availability of staff and resources as well as potential effect on long-term renal outcomes should be taken into consideration when selecting modalities of RRT for adult ICU patients.
