Critical Care Nephrology focuses on the management of acute kidney-related conditions in critically ill patients, often in intensive care settings. It involves early detection and rapid intervention for acute kidney injury (AKI), severe electrolyte imbalances, fluid overload, and complications of multi-organ failure. The specialty combines advanced monitoring, dialysis techniques, and collaboration with critical care teams to stabilize patients, prevent further kidney damage, and improve survival outcomes. Timely and targeted interventions are essential to optimize kidney function and overall recovery in high-risk patients.
