Fatores de risco no desenvolvimento de insuficiência renal aguda após cirurgia de revascularização miocárdica com CEC

Abstract

Objectives: To evaluate incidence, mortality, and risk factors related to the development of acute renal failure (ARF) after on-pump coronary artery bypass grafting (CABG), between January 2002 and November 2004. Method: Seventy four patients who underwent on-pump CABG were analyzed retrospectively and distributed into two groups according to the development of ARF. Bivariate and multivariate analyses were performed to analyze. P d" 0.05 was considered statistically significant. Results: During the period analyzed, 18 patients (24.32%) developed acute renal failure (ARF); 1 patient (1.35%), who required dialysis, died. Associated risk factors identified in-between the development of ARF was: the postoperative use of inotropic or vasoconstrictor drugs (p=0.048) and body mass index greater than 25 (p=0.004). The CPB time did not determine the ARF increase (p=0.0668). Conclusion: The CPB time was not associated with an increased of ARF following on-pump CABG.
