呼吸机相关性肺炎高危因素分析及预防对策

目的　分析呼吸机相关性肺炎的高危因素,探讨预防对策。方法　采用回顾性调查,对2001年1月～2003年12月本科确诊为呼吸机相关性肺炎(VAP)66例患者66份痰液标本进行细菌培养及药敏试验,分析人工通气时间与病原菌检出率的关系。结果　人工气道建立时间与病原菌的检出率成正相关系。结论　机械通气过程中做好各项预防措施,是控制感染的关健。

Analysis and Precautionary Measures of High Risk Factors of Ventilator Associated Pneumonia(VAP)

Objective To analyze high risk factors of VAP and investigate its precautionarymeasures. Methods We investigated retrospectively 66cases diagnosed VAP from jan. 2001 to dec. 2003and analyzed the relationship of ventilation time and pathogenic bacteria detectable rate by way ofstuding on patients To sputum bacterial culture and drug sensitive test. Results Positive correlationwas discovered between artificial airway establishment time and pathogenic bacteria detectable rate.Conclusion It was the key of control infection that all kinds of precautionary measures was well-madein mechanical ventilation.
