0.3 PERITONEAL FLUID (ABDOMEN) Flashcards
(28 cards)
Accumulation of peritoneal fluid
ascites
Hepatic disorders, such as cirrhosis, is the most frequent
cause
Transudates
Exudates:
➔ Most common cause:
Malignancy
Exudates:
Infection (peritonitis) due to?
ruptured intestinal perforation or
a ruptured appendix
Peritoneal Lavage
Agent used as lavage:
Normal Saline
___ is recommended
over the fluid:serum total protein and LD ratios to detect
transudates of hepatic origin
Serum-Ascites Albumin Gradient (SAAG)
RBC counts ____/pL are indicative of blunt trauma
injuries
> 100,000
Appearnce
Normal:
Clear and pale yellow
Appearnce
Turbid:
: Bacterial & Fungal infection
presence of bile (confirmed by bilirubin testing) means what appearance (color)?
- Green or dark-brown
➔ * Trauma
➔ * Tuberculosis
➔ * Intestinal disorders
➔ * Malignancy
Appearance?
Blood-streaked
➔ chylous and pseudochylous effusions
➔ Due to trauma or blockage of lymphatic vessels
Appearance?
Milky
Laboratory tests
WBC count normal:
<500 cells/uL
Peritonitis must be differentiated with cirrhosis.
* An absolute neutrophil count:
> 250 cells/uL or >50% of
the total WBC count = infection (peritonitis)
predominant in tuberculosis and peritoneal carcinomatosis
Lymphocytes
Detection of malignant cells
Cellular examination
Malignant cells of ovarian, prostatic, and colonic origin,
often containing ___
mucin-filled vacuoles
- Benign cells that contain concentric striations of collagen-like material
- Also associated with ovarian and thyroid malignancies
Psammoma bodies
Chemistry test
- Glucose
● ↓ than serum levels =
= bacterial and tubercular
peritonitis and malignancy
Chemistry test
Ascertain pancreatitis or damage to pancreas ↑ in gastrointestinal perforation
Amylase
Chemistry test
Requested when ruptured bladder or accidental puncture of the bladder during the paracentesis is suspected
Blood urea nitrogen and creatinine
___ = Ascertain pancreatitis or damage to pancreas
Lipase
Chemistry test
Leakage of bile into the peritoneum after surgery
Total Bilirubin
Microbiology
___ : Gram stains and bacterial cultures for both aerobes and anaerobes
Bacterial peritonitis
