pancreas Flashcards
what is the pancreas exocrine function?
pancreatic juices: tyrpsin, elastase, phospholipase A, lipase, kallikrein
what is the pancreas endocrine function?
islets of langerhans: alpha cells, beta cells, delta cells
what is acute pancreatitis?
acute is reversible
what is chronic pancreatitis?
progressive-fibrosis
what are some risk factors for pancreatitis?
- genetic (ie. cystic fibrosis)
- trauma
- alcohol abuse
- biliary tract dysfunction
- men and women equal risk
what is the pancreatitis inflammatory process?
- acute inflammation response
2. multi-organ failure
what can happen if there is obstruction of the pancreatic ducts?
- pancreatic ischemia
- gallstones
- auto digestive effects
- -pancreas enzymes in the wrong are cause destruction
what does chronic alcohol do to the pancreas?
chronic alcohol intake- 5-10% of alcoholics increases digestive enzymes
acute pancreatitis clinical manifestations
- severe pain– epigastric; may radiate to back
- n/v
- abd distention, hypoactive sounds, changes in stool from fat malabsorption
- diaphoresis
- dyspnea, shallow respirations
- low grade fever
- tachycardia
- hypotension
- jaundice
- leukocytosis
- grey turner- may be hemorrhagic pancreas, looks like bruising
- cullen’s sign- discoloration around the umbilicus (bruising) may be hemorrhagic pancreas
chronic pancreatitis clinical manifestations
it is progressive or recurring
sxs:
1. persistent or recurrent mid-epigastic pain like “heavy” or “cramp like”
- wt loss
- malnutrition
- hyper- or hypoglycemia
- steatorrhea: foul, fatty, frothy stools
pancreatitis diagnostic tests: labs
- amylase
- lipase
- glucose
- calcium
- WBCs
- triglycerides
- AST/ALT
- ranson criteria
pancreatitis diagnostic tests: radiology
- CT scan
- ultrasound
- HIDA scan
- MRI
- ERCP -endoscopic retrograde choangiopancreatography
- MRCP- magnetic resonance choangiopancreatography
pancreatitis treatment
- pain management
- iv fluids- usually 200-250 ml/hr
- NPO
- -introduce low-fat small meals, slowly after pain improves - NGT- possible if vomiting or ileum, or to reduce pancreatic secretions
- pt education
pancreatitis treatment medications
- TPN (possibly for sustained or recurrent)
- pancreatic enzymes (when taking po, if needed)
- other meds for symptoms
what complications should be prevented?
- ARDS
- pneumonia
- hypo/ hyperglycemia
- pseudo cyst
- shock
- necrotic pancreas
