经纤维支气管镜肺泡灌洗术(BAL)对免疫损害宿主并发肺炎的诊断意义已经肯定,诊断率不等,随肺炎类型和病例构成状况而异,但它在中性多核白细胞(PMN)减少并发肺炎的诊断价值目前资料甚少。作者旨在对PMN减少和非减少患者BAL及其他纤支镜检查操作的诊断结果、安全性和治疗意义进行比较,并对BAL液细胞计数与血细胞计数的关系进行观察,以确定PMN减少时是否伴随肺细胞的变化。 资料与方法 回顾性地研究了107例血液病113例次肺炎时的118例次BAL标本。Ⅰ组为PMN减少组,56例合并57例次肺炎发病,纤支镜BAL检查60例次,其中35例PMN<500·mm~3,为ⅠA组,25例500≤PMN≤1000·mm~3,为ⅠB组;Ⅱ组PMN非减少组,51例56倒次肺炎58例次纤支镜BAL检查。
The diagnostic significance of bronchoscopic bronchoalveolar lavage (BAL) in patients with immune compromised host complicated with pneumonia has been confirmed, the diagnostic rate varies, depending on the type of pneumonia and the composition of the case, but it is reduced in neutrophilic leukocytes (PMN) The diagnostic value of pneumonia is currently little information. The aim of the authors was to compare the diagnostic, safety, and therapeutic implications of PMN reduction and non-reduction in BAL and other bronchoscopic examinations and to examine the relationship between BAL fluid cell counts and blood cell counts to determine if Accompanied by changes in lung cells. Materials and Methods A retrospective study of 107 cases of hemopneumonia 113 cases of pneumonia in 118 cases of BAL specimens. Ⅰ group was PMN reduction group, 56 cases combined with 57 cases of pneumonia, bronchoscopy BAL examination 60 cases, of which 35 cases PMN <500 · mm ~ 3, for the Ⅰ A group, 25 cases of 500 ≤ pMN ≤ 1000 · mm ~ 3, for the Ⅰ B group; Ⅱ group PMN non-reduction group, 51 cases 56 inverted pneumonia 58 cases of bronchoscopy BAL.
