Peritonitis Flashcards
what is the peritoneum
large extensive membrane in the abdominal cavity
what is peritonitis
inflammation of the peritoneum caused by normal flora in the gut entering into the body cavity and causing infection
Etiology of peritonitis
- due to bacteria (especially E.coli) or chemical irritation (bile,HCL) perforation can cause chemicals to enter body cavity
- some top reasons for peritonitis:
- ruptured appendix
- perforated ulcer or diverticulum
- PID (pelvic inflammatory disorders)
- several others
what are some of the top reasons for peritonitis?
- ruptured appendix
- perforated ulcer or diverticulum
- PID (pelvic inflammatory disorder)
- several others
what is the Patho of peritonitis
- agent impacts peritoneum causing inflm
- peritoneum is large structure (inflm will be extensive) & highly vascularized so: rapid absorption of toxins and spreads easily
- thick, sticky fibrinous exudate develops (has an advantage - plugs perforation): -seals perforation -localizes inflm
- SNS limits GI motility(compensatory)
what are the advantages of the sicky fibrinous exudate that develops in peritonitis
- seals perforation (plugs perforation)
- localizes inflm
what kind of exudate develops in peritonitis?
thick, sticky, fibrinous exudate
why does the sympathetic nervous system limit GI motility with peritonitis?
compensatory mechanism, which will inhibit peristalsis, preventing contents from gut spilling out of perforation
Mnfts of peritonitis
- severe (because of size and vasculature)
- fluid shift into bowel & abdm cavity (fluid moves out of blood vessels and into body cavity (3rd spacing))
- perfusion altered: -blood shunted to site of inflm (problem is that may possibly lead to hypovolemic shock)
- pain, vomiting (vomiting is not a local mnfts it is d/t severe pain)
- Dyspnea (pain on breathing as diaphragm movement contracts & relaxes. person will adjust breathing to reduce pain)
treatment of peritonitis
NPO: -if continue to ingest food would cause more content to moveout @ site of perforation
- pre surgery need to be NPO
- IV Abx (if due to bacterial infection)
- NG suction
- Fluids & electrolytes
- anti-inflm
- narcotics (for pain)
- Sx if indicated
