Unit 19 - Body Fluids Flashcards
3 Major Closed Cavities of the Body
Heart and sac
Lungs and pleural membrane
Abdomen and peritoneal membrane
What is serous fluid?
Fluid between the organ and its covering
Functions of serous fluid
Lubrication
Movement of visceral and parietal layer
Delivery and removal of substances
What is serous fluid made up of?
Plasma filtrate
Disease states of serous fluid
Infection
Inflammation
Malignancy
Effusion definition
Pathologic accumulation of serous fluid
What causes effusion?
An imbalance of production and reabsorption
Thoracentesis
Pleural fluid
Pericardiocentesis
Pericardial fluid
Paracentesis
Abdominal fluid
Arthrocentesis
Synovial fluid
Amniocentesis
Amniotic fluid
Serous fluid in EDTA tubes are used for what testing?
Cell counts
Differential
Serous fluid in sterile heparin or SPS tubes are used for what testing?
Culture
Serous fluid in Heparin or plain tubes are used for what testing?
Chemistry (EXCEPT pH)
What are the collection requirements of synovial fluid used for pH testing?
Plain tube on ice
Are gel barrier tubes allowed for synovial fluid? Why or why not?
No.. idk why
Specimen collection requirement for synovial fluid
RT transport
ASAP analysis
Fridge storage
Remove syringe, unless when critical with sparse collection
What is the best practice for collection of synovial fluid
Bulk fluid collections allocated to tubes before transport to lab
What needs to be done to synovial fluid in a tube before chemistry analysis?
Centrifugation
Transudate definition
Effusions from systemic disorders that disrupt fluid filtration/reabsorption and hydrostatic pressure
Exudate definition
Effusions from localized disruptions of membranes
Usually bilateral (why?)
Because suggests something global like CHF, hepatic or renal disease
Usually unilateral (why?)
Because suggests something localized like a tumor on an organ, infection, inflammation, or injury in a body site
