pleural effusion判讀
-
平常臨床上除了區分exudate或transudate之外好像沒有特別指出感染的criteria
(像SBP的話PMN>250是定義，但是pleural effusion沒有必須WBC>多少？)
確定感染時要drainage
請問平常實際操作時標準如何呢？謝謝

確實沒有一個感染的criteria，但是透過驗gram stain, culture, pH, glucose，就可以大致判讀他是complicated or uncomplicated parapneumonic，有特別懷疑的原因會再加驗其他數值。
complicated parapneumonic才有drain的必要，uncomplicated用antibiotics治療pneumonia就好。
其他鑑別診斷，請愛用小麻。

From 小麻, in those of research they distribute pleural effusion into two topics; Transudates and Exudates. Roughly separate this two categories; transudates = congestive heart failure, exudates = infection. There is a great description about them in 小麻. When we talk about pleural effusion, we should know about the Light's criteria and exudative criteria. Last but not least, same as @JYC replyed 請愛用小麻.
