Pancreatitis Flashcards
0
Q
Mechanism of Disease
A
- Pancreatic duct is completely or partially blocked (gallstones, edema)
- pacreatic flow continues (enzymes)
- enzymes (trypsin) becomes activated (high levels overwhelm trypsin inhibitor)
- Trypsin begins to autodigest the pancreas and initiates inflammation
1
Q
causes for inflammation of the pancreas
A
- alcoholism
- biliary tract disease
- trauma
- cancer
- surgical procedures
2
Q
Diagnosis
A
symptoms - severe abdominal pain, worsens with eating, nausea, vomiting, edema, shock Elavated serum amylase, lipase - enzymes diffuse into blood radiological confirmation - ultrasound, CT scan
3
Q
Complications
A
- circulating enzymes decrease the serum calcium
- hemorrhagic necrosis
- glucose intolerance/hyperglycemia
- exudates into peritoneal cavity
- necrosis of mesenteric fat (death)
- increased permeability of lung alveoli (pulmonary edema)
4
Q
Prognosis
A
- self-limitting; improves on its own, may develop chronic pancreatitis
- no treatment is well established; can be fatal
5
Q
Nutrition Care Goal
A
- decrease pancreatic stimulation
- organ rest NPO
- prevent malnutrition until condition is resolved and oral intake can be resumed
- usually require a stress factor of 1.3-1.5 X BEE
- chronic alcoholism can be the underlying cause
- jejunal enteral feeding (any form of solution, if tolerated whole nutrients are better to stimulate the gut)
- TPN if enteral feeding not tolerated – pseudocyst, fistula, abcesses
- insulin if blood glucose is elevated ~ may need to reduce CHO in feedings
6
Q
Nutrition Care Remission
A
- clear fluids and advance slowly
- low fat
- small meals
- no alcohol
- may require pancreatic enzyme replacement
- continue to control blood sugars if sig damage to insulin production
7
Q
Chronic Pancreatitis
A
- recurrent acute attacks
- most commonly seen in alcoholism and occasionally in cystic fibrosis
- permanent tissue damage - enzymes are not being produced vs them leaking out
- 90% loss tissue = pancreatic insufficiency
- steatorrhea
- glucose intolerance
- malnutrition if untreated
- if gallstones are responsible; cholecystectomy
