本文就抗菌药物在外科感染应用时的几个问题分述如下: 一、药物的选择抗菌药物的疗效取决于感染类型及其主要病原菌,附表为常见外科感染的病原菌及首选药物,可供参考。但在某些病人难以在短时间内获得细菌培养结果时,根据病人的主诉、体征与辅助诊断检查的结果,亦可粗略判断致病菌的种类。如软组织、骨骼、肺、脑膜的感染以G~+球菌为主;尿路、胆道腹腔内脏器的感染以G~-杆菌为主。腹腔内感染 This article on the application of antimicrobial drugs in the surgical problems are described below: First, the choice of drugs The efficacy of antimicrobial drugs depends on the type of infection and its major pathogens, the schedule for the common surgical infection of pathogens and drug of choice for reference . However, when it is difficult for some patients to obtain the results of bacterial culture in a short period of time, the type of pathogens can also be roughly judged based on the patient’s complaints, signs and the results of ancillary diagnostic tests. Such as soft tissue, bone, lung, meningeal infection with G + cocci-based; urinary tract, biliary abdominal infections with G - - -bacteria-based. Intraperitoneal infection
