流感病毒引致肺炎和原发细菌性肺炎或继发于病毒性肺炎的细菌性肺炎的鉴别诊断较为困难,本文列举了鉴别诊断的实验室辅助方法。一次流感流行中8例流感患者发生肺部浸润,均有流感的特征性表现。男女各4例,年龄自20至74岁不等,其中4例尚有夹杂症。8例临床上均疑为流感肺炎,但都因接受抗菌素治疗而使流感和细菌性肺炎的鉴别发生困难。8例中4例并发细菌性肺炎(金黄色葡萄球菌和混合感染各2例)都获痊愈。3例死亡,内2例夹杂有冠心病。8例都未接种流感疫苗。8例中5例进行四唑氮蓝试验,3例示阴性结果(其中1例以后并
The differential diagnosis of pneumonia caused by influenza virus and primary bacterial pneumonia or bacterial pneumonia secondary to viral pneumonia is more difficult. This article lists laboratory-assisted methods for differential diagnosis. In a flu pandemic, 8 cases of influenza patients developed pulmonary infiltrates, both of which were characteristic of influenza. There were 4 males and 4 females, ranging in age from 20 to 74 years of age, of whom 4 had an inclusion disorder. Eight cases were clinically suspected of influenza pneumonia, but because of the antibiotic treatment and flu and bacterial pneumonia identification difficulties. Four of the eight patients were complicated by bacterial pneumonia (two in Staphylococcus aureus and two in mixed infection). 3 died, 2 cases were complicated with coronary heart disease. None of the 8 patients received a flu vaccine. Five of the eight patients underwent tetrazolium blue test, and three patients showed negative results (one of them was later and later)
