支气管肺泡灌洗术(BAL)在日常临床检查中发展迅速,其结果受BAL 液(BALF)保存状况的影响。对回收后的BALF 给予不同的保存时间及保存温度,研究其对检查结果的影响。对象及方法4例患者,分别患慢性风湿性关节炎伴肺纤维化、全身性红斑狼疮伴肺纤维化、嗜酸细胞性肺炎和过敏性肺炎.用纤支镜插入右中肺叶,每次注入生理盐水50ml 后回收,反复3次,获得BALF150ml。分别保存1、3、6和24h,在两种温度条件下进行(室温20℃～24℃;4℃)。然后用锥虫兰染色进
Bronchoalveolar lavage (BAL) develops rapidly in routine clinical examinations and the outcome is affected by the preservation of BAL fluid (BAL fluid). After the recovery of BALF given different storage time and storage temperature, to study the impact of the test results. Subjects and Methods 4 patients with chronic rheumatoid arthritis with pulmonary fibrosis, systemic lupus erythematosus with pulmonary fibrosis, eosinophilic pneumonia and allergic pneumonia were inserted into the right middle lobe with a bronchoscope, each injection Saline 50ml after recovery, repeated 3 times to obtain BALF150ml. The samples were stored for 1, 3, 6 and 24 h, respectively, under two temperature conditions (room temperature 20 ° C to 24 ° C; 4 ° C). Then trypan blue stain into
