What Researchers Did
Researchers reviewed clinical and experimental evidence regarding alterations in global and regional kidney perfusion and oxygenation during septic acute kidney injury (AKI) and its associated therapies.
What They Found
They found that the renal medulla is highly susceptible to hypoxia early in sepsis, even when overall kidney blood flow and oxygen delivery are increased. This progressive medullary hypoxia is proposed to initiate cellular injury, and common septic AKI therapies like fluids, vasopressors, and diuretics have distinct effects on renal circulation.
