Abstract
OBJECTIVES: to evaluate the risk of postoperative complications in cardiac patients. METHODS: an evaluative study using the Tuman Score on medical records of 70 adult patients who underwent cardiac surgery at a University Hospital. The R for Windows software was used for the analyses. Descriptive statistics and bivariate analysis were employed to verify the association between the risk score and complications. The relative risk between the Tuman Score and postoperative complications was obtained through Quasi-Poisson regression, with a 95% confidence interval. RESULTS: the majority of the patients were male (58.57%), aged between 41-64 years (50%), who underwent myocardial revascularization (50%). These patients were associated with a lower risk of postoperative complications (p=0.003), (p=0.008), and (p=0.000), respectively. High-risk patients had pulmonary complications (RR=1.32, p=0.002) and neurological complications (RR=1.20, p=0.047). CONCLUSIONS: preoperative risk assessment promotes qualified care to reduce postoperative complications.
