Peritonitis Flashcards
What is peritonitis?
Inflm of the peritoneum
What is the peritoneum?
The peritoneum is the serous membrane forming the lining of the abdominal cavity
What might cause peritonitis?
- Bacteria (esp E. coli)
- Chemical irritation (eg bile, gastric acid)
- The above 2 are a result of perforation
- Pelvic Inflm Disease
What is pelvic inflm disease?
Occurs when the normal flora from the vag moves through the reproductive organs, and eventually reaches the body cavity
The peritoneum rapidly absorbs toxins and they are easily spread throughout, why is this?
Because the peritoneum is large and richly vascularized
How is the exudate associated with peritonitis described?
Thick and sticky
What are some benefits to the exudate produced in peritonitis? Are these compensatory responses?
- Localizes inflm
- Seals perforation
No, these are not compensatory responses, but they are a nice bonus
What does the SNS do when the peritoneum is inflmed?
It will limit GI motility
What is “ileus”?
This means complete cessation of peristalsis
With peritonitis, there is a distinct fluid shift. Why is this happening and where does the fluid collect?
- Happens d/t vasodilation, hyperemia, exudate
- Shifts into the bowel and body cavity
What is it called when fluid shifts into cavities?
Third-spacing
What is a severe complication of unresolved fluid shift?
Hypovolemic shock
In peritonitis, there is _______ of blood d/t inced hyperemia.
Shunting
Mnfts of peritonitis:
- Fever
- Pain
- Vomiting
- Dyspnea
Why is there dyspnea with peritonitis?
Because the movement of the diaphragm irritates the inflmed peritoneum
