Causes Of Prerenal Acute Renal Failure

Decreased effective extracellular volume

Renal losses: hemorrhage, vomiting, diarrhea, burns, diuretics

Redistribution: hepatopathy, nephrotic syndrome, intestinal obstruction, pancreatitis, peritonitis, malnutrition Decreased cardiac output: cardiogenic shock, valvulopathy, myocarditis, myocardial infarction, arrhythmia, congestive heart failure, pulmonary emboli, cardiac tamponade Peripheral vasodilation: hypotension, sepsis, hypoxemia, anaphylactic shock, treatment with interleukin L2 or interferons, ovarian hyperstimulation syndrome Renal vasoconstriction: prostaglandin synthesis inhibition, a-adrenergics, sepsis, hepatorenal syndrome, hypercalcemia Efferent arteriole vasodilation: converting-enzyme inhibitors
