Analysis on pathogens and drug resistance of neonatal ventilator associated pneumonia / 国际检验医学杂志

ABSTRACT

Objective To understand the characteristics of pathogenic bacteria and drug resistance of ventilator-associated pneu-monia(VAP)in neonatal intensive care unit (NICU),and to explore the corresponding prevention and control measures,and to pro-vide the basis for the VAP antibiotic treatment.Methods A total of 80 children with respiratory failure and ventilator assisted breathing were selected from the NICU as objects in this study.The clinical data,pathogenic bacteria and drug resistance were ana-lyzed retrospectively.Results In 80 cases,the incidence of VAP was 43.75% (35/80),a total of 70 strains of pathogenic bacteria were isolated,gram negative bacilli accounted for the highest proportion,accounting for 81.43% (57/70).Pseudomonas aeruginosa, Klebsiella pneumoniae were the most common gram negative bacilli.Gram positive cocci accounted for 8.57% (13/70),which domi-nated by methicillin resistant Staphylococcus aureus,in addition to susceptible to vancomycin,but resistant to the other antibiotics. Conclusion Gram negative bacillus are the main bacteria in VAP cases,and which are multiple drug-resistant pathogens.
