[Continuous renal replacement therapy for acute kidney injury]

Area of Science:

• Critical care medicine
• Nephrology
• Renal replacement therapy

Context:

• Acute kidney injury (AKI) is a frequent complication in critically ill patients, contributing significantly to morbidity and mortality.
• Continuous renal replacement therapy (CRRT) is a key intervention for managing metabolic and fluid disturbances in AKI.
• CRRT necessitates invasive procedures like central venous catheterization and anticoagulation, posing potential risks.

Purpose:

• To provide an overview of Continuous Renal Replacement Therapy (CRRT) in the context of critical illness and acute kidney injury.
• To discuss the technical aspects, including vascular access and anticoagulation strategies for CRRT.
• To highlight the importance of fluid management and substitution fluid selection in CRRT protocols.

Summary:

• Continuous renal replacement therapy (CRRT) is essential for managing acute kidney injury (AKI) in critical care, effectively controlling fluid and electrolyte imbalances.
• CRRT procedures involve central venous catheter insertion and anticoagulation, with heparin being common but citrate emerging as an alternative.
• Optimal CRRT management includes careful consideration of substitution fluid choice and adherence to recommended dosages, such as 25 ml/kg/h.

Impact:

• CRRT plays a vital role in improving outcomes for critically ill patients with AKI.
• Understanding CRRT's complexities, including potential complications and evolving anticoagulation methods, is crucial for clinical practice.
• Standardized approaches to CRRT, including fluid selection and dosing, can optimize patient management and potentially reduce morbidity and mortality.
