title: [Risk factors of surgical site infection in newborn infants].
abstract: OBJECTIVE
  Was to estimate the risk factors for surgical site infections (SSJ) in the newborn infants.
  
  
  METHODS
  We retrospectively analyzed medical records of 381 operated newborn infants in order to estimate the rate of SSI and risk factors. All types of operations were divided according to contamination of surgical wound /CDC classification: clean, clean-contaminated, contaminated and dirty infected/. Additionally we evaluated risk factors such as: birth weight, gestational age, congenital infection, additional surgery, other congenital defect and invasive procedures like: mechanical ventilation and presence of central venous line. Descriptive statistics and odds ratios with 95% confidence intervals were applied in univariate statistical analysis.
  
  
  RESULTS
  The mean incidence of SSI was 37%. According to CDC classification SSI rate were 27%, 35%, 46%, 71% respectively. The most important risk factors of SSI were: mechanical ventilation (IS:10.80), central line (IS:8.20), birth weight below 1500 g (IS:5.03) and congenital infection (IS:4.74). The risk of SSI depended on the type of surgery. The incidence of infections was significantly higher for contaminated and dirty-infected wounds than for clean and clean-contaminated. Risk factors for SSI were similar for clean and clean-contaminated wounds as for all study group.
  
  
  CONCLUSIONS
  The premature newborns who underwent surgery, were mechanically ventilated, with venous access had the highest risk of SSI. The significance of risk factors was the same for the total study group for every type of surgery wound.
