目的了解呼吸机相关性肺炎(VAP)的病原菌及药敏情况,为临床治疗提供依据。方法对承德医学院附属医院重症监护病房(ICU)37例VAP患者的痰培养及药敏结果进行回顾性分析。结果VAP患者的细菌学培养以G-杆菌为主,占76.3%;其中铜绿假单胞菌占28.8%,嗜麦芽窄食假单胞菌占13.6%,鲍曼不动杆菌占10.2%。药敏试验:VAP对多数抗生素耐药率较高。结论必须加强ICU机械通气患者下呼吸道细菌检测,采取多种防治措施,在治疗VAP时应根据药敏结果合理使用抗生素。
Objective To understand the pathogens and drug susceptibility of ventilator-associated pneumonia (VAP) and provide basis for clinical treatment. Methods Thirty-seven VAP patients in intensive care unit (ICU) of Chengde Medical College Hospital were retrospectively analyzed for sputum culture and drug susceptibility. Results The bacteriological culture of VAP patients was mainly G-bacilli, accounting for 76.3%. Of these, Pseudomonas aeruginosa accounted for 28.8%, Stenotrophomonas maltophilia accounted for 13.6% and Acinetobacter baumannii accounted for 10.2%. Drug susceptibility test: VAP higher resistance to most antibiotics. Conclusion It is necessary to strengthen the detection of lower respiratory tract bacteria in ICU patients with mechanical ventilation and take various prevention and treatment measures. When using VAP, antibiotics should be used reasonably based on the susceptibility results.
