Overview

Acute Renal Failure is an abrupt reduction in kidney function defined as at-least one of the following:

1. an absolute increase in the serum levels of creatinine of 26.4 μmol/L(0.3mg/dl) or more;

2. a percentage increase in the serum levels of creatinine of more than 50%(1.5 fold increase from baseline); or

3. a reduction in volume of urine output(oliguria <0.5 ml/kg hourly for >6 hours.

Acute renal failure is increasingly common, particularly in elderly population, hospital inpatients, and critically ill patients and it carries a high mortality. The most common cause of in-hospital acute renal failure in acute tubular necrosis resulting from multiple nephrotoxic insults such as sepsis, hypotension, and use of nephrotoxic drugs or radio-contrast media. Patients at risk include elderly people, diabetics, patients with hypertension or vascular disease, and those pre-existing renal impairment.
