[Causes of azotemia in severe cranio-cerebral injuries].

The functional state of the kidneys and the level of azotemia were studied in 51 patients with a severe craniocerebral trauma. Two groups of patients were distinguished according to the preservation of diminution of glomerular filtration. Comparison between these 2 groups showed that in normal glomerular filtration azotemia was linked with the catabolic process, while in diminished glomerular filtration azotemia was also associated with a reduced renal function. The level of azotemia has been established; a higher value is evidence of renal insufficiency.
