abdominal and thoracic fluid effusions Flashcards
what is a peural effusion
fluid accumulation in the chest cavity
what is pleural effusion AKA
drowning
what is abdominal effusion
fluid accumulation in abdominal cavity
what is a red top tube used for
biochemical analysis of cholestorol and triglycerides
what is a culture tube used for
microbiological cultures
slide preparation of a non turbid fluid
centrifuge for 5 min @ 1000-1500rpm; linear or squash
slide preparation of a low cellular fluid
linear smear
slide preparation of a opaque fluid
direct (roll) smear due to high cell concentration
what is used to classify effusions
TP, SG, and TNCC
normal fluid transparency
clear to slightly turbid
normal fluid color
colorless to straw yellow
normal fluid TP
<2.5 g/dl
normal fluid SG
<1.015
normal fluid TNCC
less than 10,000/ul (AVG: 2000-6000/ul)
what is the most prodominant cell in effusions
neutrophils
what is a transudate
fluids from a non inflammatory orgin
transudate AKA
asceitic effusion
transudate causes
hypoalbuminemia, renal glomerular disease, hepatic insufficiency, uroperitoneum
transudate colory
colorless
transudate turbidity
clear
transudate SG
<1.103
transudate TP
<3.0 g/dl
transudate TNCC
<1,500 cells/ul
what results from lymphatic fluid leaks
modified transudates
causes of modified transudates
FIP, Chylous effusion, lymphatic fluid, cardiovascular disease, ruptured bladder
does a modified transudate clot
sometimes
modified transudate color
amber, red, white, mil white, yellow
modified transudates turbidity
clear to slightly turbid
modified transudate SG
variable
modified transudate TP
2.5-7.5 g/dl
modified transudate TNCC
1000-7000/ul
mos common cause of modified transudates
abdominal or plural effusion
when does eudate most commonly occur
due to inflammation
causes of exudates
inflammation, infection
what is a septic infection
bacteria and degenerative neutrophils present
what is a non-septic infection
absence of bacteria
exudate color
amber, white, red
exudate turbidity
cloudy
exudate SG
> 1.018
exudate TP
> 3 g/dl
exudate TNCC
> 5000-7000/ul
what is peritonitis
inflammation of the abdominal cavity
what does increased capillary permeability lead to
increase in neutrophils, monocytes, macrophages, increased protein
causes of infectious peritonitis or pleuritis
bacterial infections(most common), fungal protozoan and rickettsial infections, viral infections(FIP), neoplasia
what causes FIP
corona virus
FIP mortality rate
close to 100%
describe FIP fluid
odorless, straw to golden, tenacious with possible fibrin, clots when exposed to air
describe the neutrophils seen in uroperitoneum
raised nuclear borders with occasional crystals in the effusion as wall
how often do cats develop pericardial effusions from CHF
28%
how often do cats develop pericardial effusions from FIP
17%
define chyle
triglyceride rich lipoproteins from the intestines after ingestion of food containing lipids
what are important tests in chylous effusion
triglycerides and cholestorol
what causes the chyles milky white color
triglycerides and high fat content
causes of chylous effusions
ruptured thoracic duct, cardiovascular disease, lymphoma, trauma, HW disease
when is pseudochylous effusion seen
in heart disease
what is seen in exudates
bacteria, small lymphocytes, predominate nondegenerative neutrophils
what is seen in modified transudates
neoplastic cells
what is a neoplastic cell
an epithelial cell
