Resumen
The neurological injury is a latent risk in patients undergoing cardiac surgery, surgery for correction of congenital heart disease can be as high as 26%, making it necessary to have more and more accurate tools and can help reduce this incidence, regional cerebral saturation measured by NIRS represents a valid tool, which allows continuous evaluation and noninvasive.This study aims to determine an association between levels of cerebral oxygen saturation in regional patients with congenital heart disease and physiological variables determinants of oxygen supply, assuming a chronic hypoxemia in these patients. A study of correlation for these variables, for which these systematically evaluated in patients undergoing cardiac surgery at the Heart Institute Foundation Cardioinfantil, who met the inclusion criteria, to complete a sample of 31 patients, which there was no intervention, labeling it as less than the minimum risk, meeting the criteria of Helsinki.We found a significant correlation between cerebral NIRS values with the contents arterial, capillary and venous oxygen in the bivariate analysis, finding for these patients lower levels of these contents, there was no significant association with arterial or venous saturation oxygen, appears to be a significant relationship between lower levels of NIRS with neurological outcome, however these findings were not significant in the multivariate analysis.
