Nefropatia induzida por contraste após tomografia computadorizada

Abstract

Introdução: Nefropatia induzida por contraste é a terceira causa de lesão renal aguda em pacientes hospitalizados. Ela é definida como: um aumento absoluto da creatinina sérica ≥ 0,5 mg/dL e relativo em ≥ 25%. Objetivo: Nós estudamos os fatores de risco associados à nefropatia do contraste após tomografia computadorizada. Métodos: Analisamos prospectivamente 400 pacientes submetidos ao contraste endovenoso na tomografia computadorizada. Resultados: A incidência de nefropatia por contraste variou de 4 a 13,9%, conforme o critério de aumento da creatinina sérica. Diabetes e insuficiência cardíaca foram associados significativamente no aumento absoluto da creatinina sérica (O.R.: 3,5 [95% CI: 1,92-6,36], p < 0,01, 2,61 [95% CI: 1,14-6,03%], p < 0,05, respectivamente). Conclusão: Encontramos uma relação direta da infusão de contraste endovenoso na tomografia computadorizada e injúria renal, notadamente com diabetes e insuficiência cardíaca.
