Acute renal failure after cardiovascular surgery. Current concepts in pathophysiology, prevention and treatment.
Acute renal failure (ARF) is a serious complication of cardiovascular surgery and has a high mortality rate, especially with oliguria. It is usually caused by ischaemic injury of the kidney, resulting from inadequate perfusion. ⋯ Once renal failure is established close control of hydration, solutes and potentially toxic metabolites is necessary. Early renal replacement therapy with proper nutritional support appears to improve survival.
