Renal replacement therapy for acute renal failure

Area of Science:

• Nephrology
• Critical Care Medicine
• Renal Replacement Therapy

Background:

• Renal replacement therapy (RRT) has been a cornerstone in managing severe acute kidney injury (AKI) since the 1960s.
• Significant advancements in dialysis technology, including biocompatible membranes and volumetric ultrafiltration control, have enhanced AKI treatment.
• Both intermittent hemodialysis and continuous renal replacement therapies are now widely accepted for dialysis-requiring AKI.

Purpose of the Study:

• To review current concepts and evolving techniques in dialysis for acute kidney injury.
• To address controversies regarding the indication, timing, and modality selection for RRT in AKI.
• To propose a framework for choosing the optimal RRT method for AKI patients.

Main Methods:

• Literature review of advancements in renal replacement therapy for AKI.
• Analysis of current clinical practices and controversies in dialysis for AKI.
• Synthesis of evidence to suggest an approach for selecting RRT modality.

Main Results:

• Dialytic options for AKI have expanded considerably, improving patient outcomes.
• Despite advances, key aspects of RRT for AKI, such as initiation timing and modality choice, remain debated.
• Continuous renal replacement therapies have gained significant traction alongside intermittent hemodialysis.

Conclusions:

• Optimal selection of renal replacement therapy modality is crucial for AKI patient outcomes.
• Further research and consensus are needed to clarify controversial aspects of RRT in AKI.
• This review provides guidance for clinicians in choosing the most appropriate dialysis technique for AKI.
