RESUMO
Objective To investigate the clinical and etiologic characteristics and drug-resistance features of ventilator-associated pneumonia(VAP)in neonatal intensive care unit.Methods A retrospective study was conducted in 712 newborns with VAP who were admitted to the NICU from January 2007 to December 2010 and had received mechanical ventilation.The pathogenic bacteria spectrum of hospital infection were statistically analyzed.Results VAP was occurred in 69 out of 712 newborns with mechanical ventilation (incidence rate of 9.7％).The top four pathogens were saccharomyces albicans(39.2％),stenotrophomonas maltophilia(20.3％),staphylococcus epidermidis(13.5％)and klebsiella pneumoniae(9.5％),respectively.Conclusion Implementing strict measures to control the nosocomial infection can significantly reduce the incidence of VAP.Saccharomyces albicans,stenotrophomonas maltophilia,staphylococcus epidermidis and klebsiella pneumoniae were the pathogens most commonly involved.
