Pleural disease Flashcards
most of fluid formation and drainage is from
parietal pleura
vessels and lymphatics are closer to the pleural space in which pleura
parietal pleura
in a transudate protein content is
low
in inflammation the pleural effusion is an
exudate
3 examples of transudate effusions
CHF
Hepatic hydrothorax
Nephrotic syndrome
in light’s criteria for an exudate
fluid protein: serum protein ratio
> 0.5
in light’s criteria for an exudate
fluid LDH: serum LDH ratio
> 0.6
in light’s criteria for an exudate
pleural fluid LDH> 2/3 ULN for serum LDH
-
LDH is very high > 1000 in which 3 disease
empeyema
malignancy
rheumatoid
protein is especially high in
TB
MYELOMA
5 conditions in which pH is very low
empeyema malignancy TB rheumatoid esophageal rupture
gLUCOSE is very low in
empeyema TB RHEUMATOID malignancy esophageal rupture
2 things that point you in the same direction

which plueral effusion is more likely to be bilateral
transduate
4 disease that can lead to a secondary spontaneous pneumothorax
- COPD
- CF
- PJ infection
- TB
