摘要
目的探究老年患者医院获得性肺炎病原菌特点及耐药性,为后续治疗提供参考依据。方法选取2017年2月—2018年2月在该院接受治疗的老年患者187例作为研究对象,将所有患者的晨痰或者下呼吸道分泌物作为标本进行试验研究。结果该次研究共培养出菌株410株,其中革兰阴性菌对氨苄西林的耐药率最高,对头孢哌酮、庆大霉素等药物的耐药性也较高,革兰阳性菌对青霉素、庆大霉素的抗药性最高可达到100%,最低为50%。结论老年患者医院获得性肺炎病原菌中数量最多的是革兰阴性菌,且菌株的耐药性在不断提升。
Objective To explore the characteristics and drug resistance of nosocomial pneumonia pathogens in elderly patients, and to provide reference for follow-up treatment. Methods A total of 187 elderly patients treated in our hospital from February 2017 to February 2018 were selected as the study subjects. Morning sputum or lower respiratory tract secretions of all patients were taken as specimens for experimental study. Results A total of 410 strains were cultured in this study. Among them, gram-negative bacteria had the highest resistance to ampicillin. Resistance to cefoperazone, gentamicin and other drugs was also high. The resistance of gram-positive bacteria to penicillin and gentamicin could reach 100% and 50% respectively. Conclusion Gram-negative bacteria are the most common pathogens of nosocomial pneumonia in elderly patients, and their resistance to antibiotics is increasing.
