Introduction:
Contrast induced nephropathy is the third most prevalent preventable cause of acute kidney injury in hospitalized patients. It defined as an absolute increase in serum creatinine ≥ 0.5 mg/dL and relative ≥ 25% increase.
Objective:
We studied the risk factors to intravenous injection contrast nephropathy after computed tomography.
Methods:
We studied 400 patients prospectively.
Results:
The incidence of contrast induced nephropathy, with an absolute or a relative increase were 4.0% and 13.9%, respectively. Diabetes and cardiac failure were independent risk factors for CIN a relative increase de serum creatinine (O.R.: 3.5 [95% CI: 1.92-6.36], p < 0.01, 2.61 [95% CI: 1.14-6.03%], p < 0.05, respectively).
Conclusions:
We showed association between uses of intravenous injection contrast after computed tomography with acute injury renal, notably with diabetes and heart failure.
