Critical Care Nephrology

Critical care nephrology is a subspecialty of nephrology that focuses on the diagnosis and management of acute kidney injury (AKI) in critically ill patients. Critical care nephrologists are specialized physicians who work closely with intensivists, critical care nurses, and other healthcare professionals to provide comprehensive care to patients with AKI in the ICU.

AKI is a common complication of critical illness and can lead to significant morbidity and mortality if not recognized and managed appropriately. Critical care nephrologists play a key role in the early recognition and diagnosis of AKI and provide expert management of complex cases.

The management of AKI in critically ill patients typically involves a combination of supportive care measures, such as fluid and electrolyte management, and targeted interventions aimed at treating the underlying cause of AKI. Critical care nephrologists are trained to use a variety of advanced diagnostic and therapeutic tools, including renal replacement therapy (RRT), to manage AKI in critically ill patients.

In addition to the management of AKI, critical care nephrologists are also involved in the care of patients with chronic kidney disease (CKD) who require critical care support, such as those undergoing renal transplantation or receiving dialysis.

Overall, critical care nephrology is a rapidly evolving subspecialty that plays a critical role in the care of critically ill patients with AKI and other kidney-related complications.


The symptoms of acute kidney injury (AKI) can vary depending on the underlying cause and the severity of the condition. Some common symptoms of AKI may include:

  • Decreased urine output or no urine output
  • Swelling in the legs, ankles, or feet
  • Fatigue or weakness
  • Nausea and vomiting
  • Confusion or difficulty concentrating
  • Chest pain or pressure
