由于肺炎病原体的变迁和复杂化,以及抗生素和抗菌剂的迅速发展,要求抗菌治疗提高针对性和选择性。但是下呼吸道非污染标本采集的困难使临床上难以普遍确立肺炎的可靠病原学诊断,治疗多属经验性的。本文通过对细菌性肺炎治疗的回顾性调查和分析,旨在了解肺炎经验性治疗现状和存在的问题,以期改进。 Due to the changing and complicated pathogens of pneumonia and the rapid development of antibiotics and antibacterial agents, antibacterial therapy is required to improve pertinence and selectivity. However, the difficulty of collection of non-polluted specimens of lower respiratory tract makes clinical diagnosis of pneumonia is difficult to establish a reliable, mostly empirical. Through the retrospective investigation and analysis of bacterial pneumonia treatment, this paper aims to understand the status and existing problems of empiric treatment of pneumonia, in order to improve.
