作者对5年期间发生在一所教学医院中的300例医院内肺炎进行了前瞻性研究。将这些病例划分为嗜肺军团菌肺炎(LP)和非LP两组作了对比,并确定了医院内LP的危险因素。 医院内肺炎的诊断标准为:入院后至少48小时胸部X线出现新的浸润病变,并具有下列二项以上条件:(1)体温>38°℃;(2)白细胞增多>10 000/mm~3;(3)呼吸道有脓性分泌物。此外,还须有以下标本培养一项以上阳性:(1)纤支镜防污毛刷标本(PSB);(2)经胸腔针吸活检(TNA);
The authors conducted a prospective study of 300 hospital pneumonia in a teaching hospital over a five-year period. These cases were divided into Legionella pneumophila pneumonia (LP) and non-LP were compared, and to determine the risk factors for LP in the hospital. The diagnostic criteria for pneumonia in the hospital were as follows: chest X-ray showed a new infiltrative lesion at least 48 hours after admission and had the following two conditions: (1) body temperature> 38 ° C; (2) leukocytosis> 10 000 / mm ~ 3; (3) purulent respiratory secretions. In addition, one or more of the following specimens must be cultured: (1) PSB; (2) thoracic needle aspiration biopsy (TNA);
