本文就肺心病急性加重期抗生素的选用及心力衰竭时治疗的几点进展归纳如下。一、抗生素的选用近年来,呼吸道感染的致病菌有所变化,耐抗生素菌株及医院内感染渐增多;而且又出现一些新的致病菌,因此,抗生素的选用实属重要。医院外肺部感染的病原菌中肺炎球菌约占30～40％,革兰氏阴性杆菌占5～20％,因此对医院外感染者应针对革兰氏阳性致病菌为主。肺炎球菌感染应首选青霉素,对青霉素过敏者可选用红霉素或头孢菌素;金黄色葡萄球菌感染可选用苯唑青霉素,加用庆大霉素,也可使用红霉素、头孢菌素;若
This article on the acute exacerbation of pulmonary heart disease antibiotics and heart failure treatment options are summarized as follows. First, the choice of antibiotics In recent years, respiratory infections have changed the pathogenic bacteria, antibiotic-resistant strains and hospital infections increased; and there are some new pathogens, therefore, the choice of antibiotics is important. Pathogens outside the hospital lung infection pneumococcal accounted for about 30 to 40%, Gram-negative bacilli accounted for 5 to 20%, so outside the hospital should be targeted against Gram-positive pathogens. Penicillin should be the first choice of pneumococcal infection, allergy to penicillin may choose erythromycin or cephalosporins; Staphylococcus aureus infection may choose oxacillin, plus gentamicin, erythromycin, cephalosporin can also be used; If
