ABSTRACT

Background: Nosocomial infections are responsible for a high rate of morbidity and mortality in pediatric patients undergoing heart surgery. Our objective was to determine the incidence and associated risk factors to nosocomial infections in this group of patients.
Methods: A descriptive, prospective, clinical study was conducted in a tertiary hospital for a year. We calculated the rate of incidence, accumulated incidence and devices used. Was Applied the EPIDAT 2004 version 3.1 program OPS for obtaining of Chi-square with Yates correction for p with a confidence of 95 %, alpha of 0.05 with a degree of freedom, we calculated odds ratio, besides of the identification of microorganisms, their sensitivity and resistance to antibiotics.
Results: We calculated rates of: 45 % the incidence, 80.6 % cumulative incidence, 7.4 % of mortality, 13.3 % of case-fatality rate of infected and 2.7 % non-infected. The 44.4 % with pneumonia, 74 % associated with mechanical ventilation, 100 % nasogastric tube. The most frequently isolated microorganisms are: Acinetobacter baumanni, Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa with high resistance to antibiotics.
Conclusions: Pediatric patients undergoing heart surgery have high risk of infection heart disease, cyanogen’s have 5 times more risk. We observed a statistically significant association with infection using nasogastric probe and endotracheal tube, the risk increases to increased hospital stay. Infected patients have 4 times the risk of death.
