呼吸机相关肺炎发生原因及对策

目的探讨机械通气时呼吸机相关性肺炎（VAP）发生原因和防治对策。方法观察住MICU机械通气〉48h的患者85例。呼吸机相关性肺炎诊断：通过观察体温、气管内吸出脓性分泌物、外周血白细胞、痰细菌培养、X线胸片。结果机械通气〉48h的85例患者中，40例发生呼吸机相关性肺炎，发生率为47％；其中单纯致病菌16例，两种及两种以上致病菌24例。病原菌培养结果：铜绿假单胞菌16例、金黄色葡萄球菌12例、克雷伯杆菌16例、白色念珠菌12例、大肠埃希10例。结论铜绿假单胞菌、金黄色葡萄球菌、克雷伯杆菌、白色念珠菌是呼吸机相关性肺炎主要致病菌；缩短机械通气时间是防治肺炎的重要措施。

The causes and strategies for ventilator-associated pneumonia

Objective To explore the causes and prevention treatment strategies of ventilator-associated pneumonia (VAP) during mechanical ventilation.Methods Observations of 85 cases were made who received mechanical vetilation more than 48 hours in MICU. The diagnosis of ventilator-associated pneumonia was conducted: through observing temperature, aspirating secretions nongxing from trachea, WBC, sputum culture, and X-rays.Results 40 cases were diagnosed as VAP among 85 cases who received mechanical ventilation more ...
