SUMMARY
1. Pleural effusions can be transudative or exudative. Distinguished by comparing pleural fluid LDH & total protein to that in serum.
2. Transudate is due to systemic causes that affect the accumulation and absorption of pleural fluid. Causes: LV failure, cirrhosis, nephrotic syndrome.
3. Exudate is due to local causes. Causes: bacterial premmonia, cancer, PE.
4. Light’s criteria to differentiate b/w transudate and exudate: note that all 3 conditions must be met to be called a transudate, failing any 1 criteria makes it an exudate.
5. Transudative effusions can be misclassified as exudates during diuresis: use serum protein-pleural protein gradient (serum protein - pleural protein), with gradient > 3.1 g/dL being a transudate.
