近年来抗生素发展很快,为临床提供了有效的治疗手段,但多用、滥用现象也比较严重,抗生素使用不当不仅影响疗效,延误病情,增加毒性或过敏反应,造成经济上的浪费,更重要是导致病原菌变化,二重感染,耐药菌株急剧增加,使药品的临床使用寿命缩短。 肺部感染可由各种病原所引起,要正确选用抗菌药物必须首先获得可靠的病原学诊断,如为革兰氏阴性杆菌则应做药敏试验,作为选用药物的参考。一般中轻度感染可口服给药,治疗严重肺部感染时则大多需 In recent years, the rapid development of antibiotics, clinical treatment provides an effective means, but the use of abuse is also more serious, inappropriate use of antibiotics not only affect the efficacy, delay the disease, increase toxicity or allergic reactions, resulting in economic waste, more importantly Lead to changes in pathogens, double infection, drug-resistant strains of a sharp increase in the shorten the clinical life of drugs. Pulmonary infection can be caused by a variety of pathogens, the correct choice of antimicrobial agents must first obtain a reliable etiological diagnosis, such as Gram-negative bacteria should do susceptibility testing, as a reference drug of choice. In general mild infection can be oral administration, treatment of severe pulmonary infection are mostly needed
