目的研究探讨老年呼吸道感染患者病原细菌的临床检验方法和价值。方法对2014年4月~2016年4月确诊的160例老年呼吸道感染患者的痰液标本进行培养检验和药敏试验检测。结果所有患者的痰液标本共检出革兰氏阳性菌50株(31.30%),革兰氏阴性菌86株(53.80%)和真菌24株(15.00%),其中革兰氏阳性菌对青霉素的耐受率为63.25%~90.37%,对万古霉素不耐受;革兰氏阴性菌对氨苄西林的耐受率为91.87%~100.00%,对头孢曲松的耐受率为43.16%~83.19%。结论老年呼吸道感染患者常见病原细菌以革兰氏阴性菌为主,其临床耐药性较高,故治疗方案中应该合理进行抗生素给药治疗,以确保患者的临床疗效和康复质量。
Objective To study the clinical testing methods and value of exploring pathogenic bacteria in elderly patients with respiratory tract infection. Methods The sputum specimens of 160 elderly patients with respiratory tract infection diagnosed from April 2014 to April 2016 were tested for their culture and drug sensitivity tests. Results A total of 50 Gram-positive bacteria (31.30%), 86 Gram-negative bacteria (53.80%) and 24 (15.00%) Gram-positive bacteria were detected in sputum specimens of all patients. Gram- The tolerance rate of gram-negative bacteria to ampicillin was 91.87% ~ 100.00%, and the rate of resistance to ceftriaxone was 43.16% ~ 90.37% 83.19%. Conclusions Gram-negative bacteria are the common pathogenic bacteria in elderly patients with respiratory tract infection, and their clinical drug resistance is high. Therefore, the antibiotic therapy should be rationalized in the treatment plan to ensure the clinical efficacy and quality of rehabilitation.
