Acute Kidney Injury (AKI) is the generic term for an abrupt and sustained decrease in renal function, resulting in retention of nitrogenous (urea and creatinine) and non-nitrogenous waste products [1]. As renal failure is often asymptomatic, it must be detected by carefully tracking the serum creatinine level. Early recognition is critical. The earliest manifestations of AKI may be subtle. Losing the function of one half of the nephron mass will cause creatinine to rise from about 0.7 mg/dl only up to
1.4 mg/dl. In general, the threshold used to identify AKI is a rise in the serum creatinine level
1.0 mg/dl, but smaller elevations should be taken as early signs of trouble [2]. The major cause of intrinsic renal azotaemia is acute tubular necrosis (ATN). Pre-renal azotaemia and ischaemic ATN occur on a continuum of the same pathophysiological process and together account for 75% of the | Epidemiology |
