Pancreatitis Flashcards

0
Q

Mechanism of Disease

A
  1. Pancreatic duct is completely or partially blocked (gallstones, edema)
  2. pacreatic flow continues (enzymes)
  3. enzymes (trypsin) becomes activated (high levels overwhelm trypsin inhibitor)
  4. Trypsin begins to autodigest the pancreas and initiates inflammation

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

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)

Q

Prognosis

A
  • self-limitting; improves on its own, may develop chronic pancreatitis
  • no treatment is well established; can be fatal

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

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

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
