Prevention of Acute Oliguric Renal Failure
Acute renal failure may be defined as the inability of urine output to maintain normal plasma urea, creatinine, hydrogen ion balance and volume status. In normal 70 kg adults a sustained urine output of less than 0.5 ml/kg/h will usually result in a gradual rise in plasma creatinine and urea concentrations. However, some patients may develop or be converted to a non oliguric form of acute renal failure and, providing urine volumes are high enough, they provide sufficient removal of waste products to avoid the need for haemofiltration. The latter has many advantages: these include less nursing intensity, fewer complications related to bleeding and lower costs.
