目的了解近两年住院病人下呼吸道感染病原菌分布及耐药性分析。方法从住院病人痰培养的标本中分离出的病原菌进行回顾性分析。结果革兰阴性杆菌占81.6%,革兰阳性菌占8.7%,酵母菌占7.3%。其中铜绿假单胞菌是在医院中最常见致病菌之一,占总病原菌的43%,其次为大肠埃希菌占6.8%,肺炎克雷伯为5.8%,醋酸钙鲍曼复合不动杆菌占5.6%,嗜麦芽寡单胞菌占4.8%;革兰氏阳性菌主要为金黄色葡萄球菌占6.8%;真菌以白假丝酵母菌为主占5.2%。结论本文统计的数据与其它文献报道不相符,特别是铜绿假单胞菌检出率和耐药性更为严重,也许是本院医生用药习惯的不同,随着用药时间的推延,药物敏感性也发生变化,所以临床用药应根据药敏结果,再结合用药经验,更合理地使用抗生素以控制耐药性的进一步恶化。
Objective To understand the distribution and drug resistance of pathogenic bacteria in lower respiratory tract inpatients in recent two years. Methods The pathogen isolated from sputum culture samples of inpatients was retrospectively analyzed. Results Gram-negative bacilli accounted for 81.6%, Gram-positive bacteria accounted for 8.7%, yeast accounted for 7.3%. Pseudomonas aeruginosa is one of the most common pathogenic bacteria in the hospital, accounting for 43% of the total pathogenic bacteria, followed by Escherichia coli accounted for 6.8%, Klebsiella pneumoniae 5.8%, Bauer calcium acetate complex does not move Accounting for 5.6% of bacilli and 4.8% of Stenotrophomonas maltophilia; Gram-positive bacteria mainly accounted for 6.8% of Staphylococcus aureus; and Candida albicans accounted for 5.2%. Conclusion The statistical data in this paper is inconsistent with other reports, especially Pseudomonas aeruginosa detection rate and drug resistance is more serious, perhaps the hospital doctor medication habits are different, with the delay of medication time, drug sensitivity Also changed, so clinical medication should be based on drug susceptibility results, combined with drug experience, more rational use of antibiotics to control further deterioration of resistance.
