目的分析研究重症监护室鲍曼不动杆菌感染分布情况,并对其耐药性进行分析。方法选取从重症监护室送检标本中分离得到的非重复性鲍曼不动杆菌菌株198株作为研究对象,分析鲍曼不动杆菌菌株的标本来源,并通过耐药试验判断鲍曼不动杆菌对临床常用10种抗生素的耐药性。结果鲍曼不动杆菌在痰液及咽拭子标本的构成比最高,占81.8%,显著高于其他标本的构成比。除多粘菌素B之外,鲍曼不动杆菌对其余9种临床常见抗生素的耐药率均达到90%以上。结论重症监护室鲍曼不动杆菌感染主要来源于痰液及咽拭子标本,且对多数临床常用抗生素都有较高的耐药性,要做好重症监护室的清洁工作,控制鲍曼不动杆菌的感染传播,合理用药,提高治疗效果。
Objective To analyze the distribution of Acinetobacter baumannii infection in intensive care unit and analyze its drug resistance. Methods A total of 198 non-repetitive Acinetobacter baumannii isolates from the intensive care unit were selected as research objects to analyze the origin of Acinetobacter baumannii strains. The Acinetobacter baumannii Commonly used in clinical 10 kinds of antibiotic resistance. Results Acinetobacter baumannii had the highest proportion in sputum and throat swab specimens, accounting for 81.8%, which was significantly higher than that of other specimens. In addition to polymyxin B, Acinetobacter baumannii resistance rate of the remaining 9 kinds of clinical common antibiotics reached more than 90%. Conclusion Acinetobacter baumannii infection in intensive care unit mainly comes from sputum and throat swab specimens, and has high resistance to most commonly used antibiotics. To do intensive care unit cleaning work, to control Bowman not Acinetobacter infection spread, rational use of drugs to improve the therapeutic effect.
