title: [Risk factors and pathogens of nosocomial infection in preterm infants].
abstract: OBJECTIVE
  To investigate the risk factors and the pathogens of nosocomial infection in preterm infants.
  
  
  METHODS
  The medical data of 197 preterm infants with nosocomial infection were retrospectively studied.
  
  
  RESULTS
  The incidence of nosocomial infection was 22.2% (197/887). Small gestational age (OR=4.125, p<0.05), low birth weight (OR=5.450, p<0.05), mechanical ventilation therapy (OR=4.435, p<0.05) and delayed enteral feedings (OR=3.765, p<0.05) were found to be important risk factors for nosocomial infection. Klebsiella was the main pathogen (22.3%), followed by Staphylococcus (18.4%).
  
  
  CONCLUSIONS
  Hygienic handwashing, decreasing invassive procedures and an early start of enteral feeding are crucial for preventing nosocomal infection in preterm infants. Klebsiella is the main pathogen of nosocomal infections.
