Electrolyte, acid-base, and medication management with renal replacement therapy

Area of Science:

• Nephrology
• Critical Care Medicine

Background:

• Kidney function is vital for fluid and electrolyte homeostasis.
• Artificial renal replacement therapy (RRT) is essential for managing acute kidney injury (AKI) and chronic kidney disease (CKD).
• Regulating electrolyte and acid-base balance during RRT presents significant clinical challenges.

Purpose of the Study:

• To review the management of electrolyte shifts during RRT.
• To discuss strategies for addressing acid-base disturbances in patients undergoing RRT.
• To highlight medication considerations in the context of RRT.

Main Methods:

• Literature review focusing on RRT in inpatient settings.
• Analysis of management strategies for intermittent hemodialysis (IHD).
• Review of continuous RRT (CRRT) protocols and their impact on homeostasis.

Main Results:

• Effective management of electrolyte imbalances requires careful RRT prescription.
• Acid-base disturbances necessitate tailored RRT approaches.
• Medication dosing and administration must be adjusted based on RRT modality and patient status.

Conclusions:

• Optimizing RRT is crucial for maintaining fluid and electrolyte balance in critically ill patients.
• A comprehensive understanding of RRT's effects on acid-base status is necessary.
• Individualized medication management is key to safe and effective RRT.
