两种方法处理血性胸水后抗酸染色结果比较分析

Comparative analysis of acid fast staining results after bloody pleural effusion treatment with two methods

目的:探讨对血性胸水进行不同前期处理,比较抗酸性杆菌阳性率的差异。方法:132例血性胸水,同时用离心沉淀直接涂片和使用溶血剂破坏血性胸水的红细胞、降低胸水蛋白质含量后涂片,进行抗酸染色。结果:直接离心涂片共查出5份抗酸染色阳性标本,加溶血剂后查出13份抗酸染色阳性标本。结论:血性胸水经过加溶血剂处理,可提高抗酸染色阳性检出率,操作简便、快速、价廉,是基层医院的一种有效方法。

Objective：To explore different methods on treatment of bloody pleural effusion, and compare the differences of them in acid- fast bacillus positive rate. Methods： 132 bloody pleural effusion samples were handled in two ways, some were conducted direct smear with centrifugal precipitation, while the rest were conducted smear after reducing protein content in pleural effusion with lytic agents. Then acid - fast stain was carried out on these samples. Results： 5 acid - fast stain samples were found positive by direct smear with centrifugal precipitation, while 13 positive samples were found by adding lytic agents. Conclusion： Treatment of bloody pleural effusion with lytic agents can improve the positive rate ＂of acid - fast bacillus, which was an effective method used in primary hospital due to simple operation, rapidness and low cost.
