[Acute renal failure in intensive care unit: risk and prognostic factors]. / L'insuffisance renale aigue en milieu de reanimation: facteurs de risque et pronostiques.

The purpose of this study is to specify the incidence, the risk and prognostic factors of the ARF. Transverse study about all the patients hospitalized in our department during one year. The incidence of the ARF was 18%. The state of shock, sepsis, high SAPS and advanced age were the main risk factors of the ARF happening. The mean number of multiple organ failure was 3.8 +/- 1.4 in the died patients versus 2.2 +/- 0.3 in the survivors. The whole mortality was about 46.3%. In our department, the incidence of the ARF is lower than in the literature. Age, SAPS, sepsis and state of shock are the main risk factors. ARF mortality is still high particularly in the case of shock or multiple organ failure.
