重症医学科医务人员咽部带菌情况的调查

目的了解重症医学科（ICU）医务人员的咽部细菌寄殖情况,分析其与重症患者呼吸机相关性肺炎（VAP）发生率的关系。方法回顾性分析ICU医务人员咽拭子培养结果和同期机械通气患者痰培养结果及VAP发生率。结果连续6个月,医务人员咽拭子阳性率为6.25%~15.6%,VAP发生率在22.2%~28.5%之间;咽拭子培养出致病菌与机械通气患者痰培养出细菌一致;检出株数有随VAP发生率增加而增加趋势。结论医务人员与机械通气并发肺部感染患者之间存在交叉感染;医院感染管理工作中,需要重视医务人员医院感染的预防及控制。

Objective To study the results of bacteria colonization in pharyngeal of medical staff in ICU and analyze the relationship between the incidence of ventilator associated pneumonia （VAP） and the results. Methods The results of pharyngeal swab culture of medical personnel and sputum culture from patients accepted mechanical ventilation and the incidence of VAP in ICU were collected and analysed retrospectively. Results The positive rates of swab and the incidence of VAP range from 6.25%to 15.6%, 22.2%to 28.5%during the consecutive 6 months,respectively. Bacteria cultivated from Pharyngeal swab were consistent with From sputum in patients with mechanical ventilation .with the increase of the incidence of VAP, bacterial strains cultivated from Pharyngeal swab increased. Conclusion The cross-infection between patients implemented mechanical ventilation and medical personnel in ICU exsited.Prevention and control of hospital infection of medical personnel in ICU should be focused on.
