摘要目的 分析新生儿呼吸机相关性肺炎(VAP)发生的相关因素,为VAP的防治提供一定的理论依据.方法 回顾分析2006年1月至2009年12月温州市第三人民医院NICU呼吸机治疗的145例危重新生儿的临床资料.结果 145例机械通气患儿中发生VAP 52例,发生率为35.86%,主要相关因素为胎龄、出生体质量、机械通气时间及再插管情况等,两组比较差异有统计学意义(P<0.05).病原菌主要为条件致病的革兰阴性杆菌.结论 VAP与胎龄、出生体质量、机械通气时间及再插管情况密切相关,规范应用呼吸机、加强无菌操作、选择有效抗生素,可以控制VAP的发生和发展.

abstractsObjective To investigate the relevant factors of neonatal ventilator-associated pneumonia(VAP),and to provide a theoretical basis of prevention and treatment.Methods Retrospective analyed the clinical data of 145 critically ill neonates,who were treated with mechanical ventilator from Jan 2006 to Dec 2009 in the Third People′s Hospital of Wenzhou City,NICU.According to whether the neonates were occurred VAP,they were divided into two groups:VAP group(52 cases) and without VAP group(93 cases).Results Fifty-two out of the 145 neonates developed VAP.The incidence of VAP was 35.86%,the main relevent factors were the gestational ages,birth weights,the duration of mechanical ventilation and the times of intubation.There was significant difference between the two groups (P<0.05).The main pathogens were opportunistic bacteria,and mostly were G-bacilli.Conclusion The incidence of VAP has a close conclusion with the gestational ages,the birth weights,the duration of mechanical ventilation and the times of intubation.Regulate the use of breathing machine,strengthen aseptic operation,and select effective antibiotic can control the occurrence and development of VAP.
