Analysis of Risk Factors and Nursing of Neonatal Ventilator-associated Pneumonia

Objective To explore the risk factors and nursing strategy of neonatal ventilator-associated pneumonia(VAP).Methods A retrospective case-control study was conducted on 168 neonates,divided into VAP group and control group,who needed mechanical ventilation for more than 48 hours.Non-conditional Logistic regression analysis was made to determine independent predictors of VAP.Results There were 45 cases of VAP in 168 neonates who were ventilated for more than 48 hours.The incidence was 26.8%,41.89/1 000 ventilator days.The mortality rate was 7% in VAP neonates and that was 5% in control group neonates(P0.05).The main pathogen was G-bacterium(83%).Multivariate Logistic regression analysis showed that duration of mechanical ventilation,birth weight,endotracheal suction were predicted factors for the development of VAP.Conclusion The development of neonatal VAP was associated with patient’s internal agent and external medical environments.Minimizing endotracheal suction frequency,reducing duration of mechanical ventilation as soon as possible,adopting comprehensive measures were recommended to prevent neonatal VAP.
