摘要
目的:了解重症监护病房(ICU)呼吸机相关性肺炎(VAP)细菌的菌群分布及其耐药性状况.方法:对ICU146例机械通气患者的病原学检查,并行细菌耐药性分析.结果:72例检出279株致病菌,其中革兰阴性细菌(G-菌)占63.1%,革兰阳性细菌(G+菌)占17.9%,真菌占19.0%,药敏结果显示这类菌株都呈现多重耐药现象.结论:VAP病原菌以G-菌为主,呈多重耐药,预防和控制VAP发生的最有效的方法在于抗生素的合理应用.
Aim: to find out the distribution and its resistance state of ventilator--associated pneumonia(VAP) in ICU. Methods: etiological examination on 146 mechanical ventilation cases in ICU and analysis of bacteria resistance. Results: 279 pathogenic bacteria were founded in 79 cases, consisting of 63.1% gram--negative, 17.9% gram--positive and 19.0% fungus. The results showed that this kind of virus displayed its multiple drug resistance. Conclusion: Gram bacteria were the main kind of VAP pathogen and it showed the multiple resistance. Therefore, the most effective way of prevention and control of VAP is the rational use of antibiotics.
