Body Fluid Analysis Flashcards
Fluid accumulation in the pleural, pericardial and peritoneal cavities
Serous effusion
Bilateral due to systemic conditions leading to increased capillary hydrostatic pressure or decreased plasma oncotic pressure
Transudates
Unilateral, associated with localized disorders that increase vascular permeability or interfere with lymphatic resorptiob
Exudate
Can cause transudates
Congestive heart failure
Hepatic cirrhosis
Hypoproteinemia (nephrotic syndrome)
Pleural fluid/serum protein ratio
Pleural fluid/serum LD
Pleural fluid of LD level greater than 2/3 of the serum upper limit
Light criteria
How would you rule out malignancy and infection
Cytology
Appropriate bacterial stain
Quantitative DNA analysis
Milky white
Lymphocytosis
Tag > 110
Chylomicrons present
Chylous
This can provide rapid chemical evidence for tuberculous effusion
ADA
Most reliable diagnostic tool for identifying pericardial exudate and transudate
Light criteria
Pathologic accumulation of excess fluid in the peritoneal cavity
Ascites
If the SAAG is greater than 1.1
Portal hypertension
Liver problems
CHF
