CM LEC - Pericardial and Peritoneal Fluid Flashcards
(58 cards)
pericardial effusion suspected when ??
there is cardiac compression during physician’s examination
pericardial effusion suspected when ??
there is cardiac compression during physician’s examination
Primary causes of pericardial transudates (HUA)
uremia, hypothyroidism, and autoimmune disorders
common/important lab tests for pericardial fluid
- Fluid:serum protein
* Lactic dehydrogenase ratios
what type of tests are perfomed when endocarditis is suspected
culture and G/S
• Common infection-causing organism in pericardial fluid (4)
o Streptococcus
o Staphylococcus
o Adenovirus
o cox- sackievirus
- accumulation of fluid between the peritoneal membranes
Ascites
– fluid between the peritoneal membranes (not “peritoneal fluid”)
Ascitic fluid
-causes of ascitic transudates:
hepatic disorders (cirrhosis)
-causes of ascitic exudates:
bacterial infections (peritonitis)
– introduced to peritoneal cavity as lavage to detect abdominal injuries that have not yet resulted in fluid accumulation
Normal saline
– sensitive test to detect intra-abdominal bleeding in blunt trauma cases
Peritoneal lavage
RBC count in blunt trauma injuries
> 100 000/mL
recommended over the fluid:serum total protein and LD ratios to detect peritoneal transudates of hepatic origin
Serum-ascites albumin gradient (SAAG)
Other tests to detect peritoneal transudates of hepatic origin
fluid:serum total protein and LD ratios
gradient of a peritoneal transudate effusion of hepatic origin
> 1.1
lower gradients
what type of peritoneal effusion
exudative
normal WBC count in peritoneal fluid
increased WBC count in peritoneal fluid associated with
bacterial peritonitis, cirrhosis
to differentiate bacterial peritonitis and cirrhosis, what test is performed
absolute neutrophil count
increased lymphocytes in peritoneal fluid associated with
TB
substance in peritoneal fluid: with concentric striations of collagen-like material
- seen in benign conditions, ovarian and thyroid malignancies
Psammoma bodies
what chemical test/s is/are elevated in GIT perforations
AMS/ALP
What test performed when: a ruptured bladder or accidental puncture of the bladder during the paracentesis is of concern
BUN and Creatinine
