目的:探讨老年人支气管肺部感染病原菌分布特点,提高诊治水平。方法:选取本院2013年10月~2014年10月收治确诊的48例老年人支气管肺部感染患者为研究对象,对其进行痰培养,并对临床诊疗结果进行分析。结果:连续三次痰培养为单一细菌者仅占6.25%;而42例次为阳性结果中54.76%为革兰氏阳性杆菌,30.95%为革兰氏阴性杆菌;非相同单一痰菌培养中,所分离出的病原菌以革兰氏阳性杆菌为主,占56.76%;16例抗生素应用与药敏结果不一致,15例有效;22例抗生素应用与药敏结果一致中,21例有效。结论:对老年人支气管肺部感染患者进行痰培养与药敏试验,对其肺部感染的治疗有着十分重要的作用。
Objective: To investigate the distribution of pathogenic bacteria in bronchial pulmonary infection in the elderly and to improve the diagnosis and treatment. Methods: Forty-eight elderly patients with bronchial pneumonia admitted from October 2013 to October 2014 in our hospital were enrolled in this study. Their sputum culture was performed and the clinical diagnosis and treatment results were analyzed. Results: Only three consecutive sputum cultures accounted for 6.25% of the single bacteria; 42 cases were positive, 54.76% were Gram-positive bacilli and 30.95% were Gram-negative bacilli. Gram-positive bacilli were the main pathogens isolated, accounting for 56.76%; 16 cases of antibiotics were inconsistent with susceptibility results, 15 cases were effective; 21 cases of antibiotics were consistent with drug susceptibility results. Conclusion: Sputum culture and drug susceptibility tests in elderly patients with bronchial pulmonary infection have a very important role in the treatment of pulmonary infection.
