coverage and prevention of infection
acute tubular necrosis
damage to the renal tubules due to presence of toxins in the urine or to ischemia -sepsis is most common cause

CRRT (continuous renal replacement therapy)
typically done in the ICU. It is special because *never more than 80ml is out of the body at one time*. Thus, it does not stress the cardiovascular system as much -uremic toxins and fluids are removed while acid base status and electrolytes are adjusted slowly
