Drug Information available for: Iohexol

Arm Intervention/treatment
Experimental: Iohexol plasmatic clearance Drug: IOHEXOL
Estimate iohexol clearance at the end of stay in intensive care for patients who had an episode of acute renal failure.
Other Name: Omnipaque ®

Primary Outcome Measures :
  1. Frequency of patients with a clearance of iohexol < 60 ml/min/1m273 at the end of ICU hospitalisation. [ Time Frame: 24 hours ]
    Iohexol clearance pharmacokinetics

Secondary Outcome Measures :
  1. Correlation between non resolutive renal at the end of ICU (iohexol clearance < 60 ml/min/1m273) and creatinine clearance < 60 ml/min/1m273 at 6 month after ICU. discharge [ Time Frame: Six month after ICU discharge ]
  2. Number of risk factors associated with non resolutive among : Age Previous renal function Comorbidities Severity parameters of renal aggression Acute severity of parameters during the ICU hospitalisation [ Time Frame: 24 hours ]
  3. Correlation between serum creatinine derived measurements of Glomerular Filtratio Rate and iohexol clearance. [ Time Frame: 24 hours ]
