良恶性胸水的鉴别多数不难,但仍有20％的病例经临床各项检查难以确诊,近年来胸水生化检查对两者的鉴别进展较快,本文就此作一简要概述。 1.pH及糖的测定胸水pH对良恶性胸水的鉴别具有一定的实用价值。1983年余桂清等测定60例胸腹水pH,结果化脓性多<7.2,结核性在7.21～7.40之间,而癌性则>7.4。吴洁等测定57例胸水pH,结果表明pH<7.3,特别<7.2时应考虑化脓性, Most benign and malignant pleural effusion is not difficult to identify, but there are still 20% of the cases difficult to diagnose by clinical examination in recent years, pleural effusion biochemical examination of the rapid progress of the identification of the two, this article to make a brief overview. 1.pH and sugar determination of pleural effusion pH differential diagnosis of benign and malignant pleural effusion has some practical value. In 1983 Yu Guiqing 60 cases of determination of pleural effusion pH, the results of purulent more than 7.2, tuberculosis in 7.21 ~ 7.40, while the cancer was> 7.4. Wu Jie determination of 57 cases of pleural effusion pH, the results show that pH <7.3, in particular, <7.2 should consider suppurative,
