this is a life-threataening acute inflammation of visceral/parietal peritoneum and endothelial lining of abd cavity or peritoneum
peritonitis

DIFFUSE PERITONITIS may increase abd presure and distention. this increases the risk for what??
risk for resp problems
*bigger and bigger stomach pushes diaphragm up decreasing deep breathing
-
what can third spacing into the peritoneal cavity result in?
loss of circulatory volume
*increase risk for hypovolemic shock and kidney failure
-
how does third spacing happen in peritonitis?
infection continues therefore shunting extra blood to that area continues
fluid shifts from the extracellular fluid compartment into the peritoneal cavity, connective tissue, and GI tract

- xray - dilation, edema, and inflammation of small and large intestine
-
nonsurgical management of peritonitis
- iv fluids
- broad spectrum ABX
- daily wt monitored
- fluid volume assessed
- ng suction - rid of fluid
- NPO status
- o2
- pain managment
*avoid resp issues by decompression of stomach
-
surgical management of peritonitis
exploratory laparotomy
-
peritonitis
post op care
- semi fowlers position
- wound care:
- care of incisions and drains
- peritoneal irrigation
- IV fluid replacement
-
inflammation of the gastrointestinal tract
gastroenteritis
-
increase int he frequency and water content of stools or vomiting results form this condition
gastroenteritis - inflamm of mucous membranes of stomachand intestinal track
