Pancreatitis Flashcards
pancreatitis
- Islets of Langerhans: secrete insulin and glucagon
- Pancreatic tissues secrete digestive enzymes that break down carbs, proteins, and fats
- Pancreatitis: autodigestion of the pancreas by pancreatic digestive enzymes that activate prematurely before reaching the intestines
- MOA: unclear
- Inflammation of the pancreatic tissue causes duct obstruction, which can lead to increased pressure and duct rupture, causing the release of pancreatic enzymes into the pancreatic tissue
- Can result in pancreatic inflammation, necrosis, hemorrhage
acute vs. chronic pancreatitis
- Acute pancreatitis: inflammatory process due to activated pancreatic enzymes autodigesting the pancreas ranging from mild to necrotizing hemorrhagic pancreatitis (widespread bleeding and necrosis)
- Classic presentation of acute attack: severe, constant, knifelike pain (LUQ, midepigastric, and/or radiating to the back)
- Chronic pancreatitis: progressive, destructive dz of inflammation and fibrosis of pancreas
how can chronic pancreatitis be classified?
- Chronic calcifying pancreatitis: assoc with alcohol use disorder
- Chronic obstructive pancreatitis: assoc with cholelithiasis
- Autoimmune pancreatitis
- Idiopathic and hereditary pancreatitis
pancreatitis: health promotion and dz prevention
- Avoid excess alcohol consumption
- Eat a low fat diet
pancreatitis: risk factors
- Biliary tract dz: gallstones can cause a blockage where the common bile duct and pancreatic duct meet
- Alcohol use: primary cause of chronic pancreatitis is alcohol use disorder
- Times of inc alcohol consumption, like vacations or holidays, are assoc with acute pancreatitis
- Inc age: more common in older adults
- Endoscopic retrograde cholangiopancreaticography (ERCP): post procedure complication
- GI surgery
- Metabolic disturbances: hyperlipidemia, hyperparathyroidism, hypercalcemia
- Kidney failure or transplant
- Genetic predisposition
- Trauma
- Penetrating ulcer: gastric or duodenal
- Medication toxicity
- Viral infections: coxsackievirus B and HIV
- Cigarette smoking
pancreatitis: expected findings
- Sudden onset of severe, boring pain (goes thru body)
- Epigastric, radiating to back, left flank, or left shoulder
- Worse when lying down
- Pain relieved somewhat by fetal position or sitting upright, bending forward
- n/v
- Weight loss
- Seepage of blood stained exudates into tissue as a result of pancreatic enzyme actions
- Ecchymoses on the flanks: Turner’s sign
- Bluish gray periumbilical discoloration: Cullen’s sign
- Generalized jaundice
- Absent or dec bowel sounds (possible paralytic ileus)
- Warm, moist skin and fruity breath: evidence of hyperglycemia
- Ascites
- Tetany due to hypocalcemia
- Trousseau’s sign: hand spasm when BP cuff is inflated
- Chvostek’s sign: facial twitching when facial nerve is tapped
pancreatitis: lab findings
- Serum amylase: inc w/in 12 to 24 hr and remains inc for 2-3 days
- Continued elevation can indicate pancreatic abscess or pseudocyst
- Serum lipase: inc slowly but remains inc for up to 2 weeks
- Urine amylase remains inc for up to 2 weeks
- Inc in enzymes indicate pancreatic cell injury
- WBC count: inc due to infection and inflammation
- Platelets: dec
- Serum calcium and magnesium: dec due to fat necrosis w/ pancreatitis
- Serum liver enzymes and bilirubin: inc with assoc biliary dysfunction
- Serum glucose: inc due to a dec in insulin production by the pancreas
- ESR: elevated
pancreatitis: diagnostic procedures
CT scan w/ contrast: reliably diagnostic for acute pancreatitis
pancreatitis: nursing care
- Rest pancreas:
- NPO: no food until pain free
- For severe pancreatitis: TPN or jejunal feedings
- Contraindicated if paralytic ileus develops, less risk of hyperglycemia
- When diet is resumed: bland, high protein, low fat diet with no stimulants (caffeine)
- small, frequent meals
- Administer antiemetic as needed, as prescribed
- NG tube: gastric decompression
- For severe vomiting or paralytic ileus
- No alcohol consumption
- Smoking
- Limit stress
- Pain mgmt
- Position client for comfort: fetal, side lying, HOB elevated, sitting up or leaning forward
- Administer analgesics
- Monitor blood glucose, and provide insulin as needed: potential for hyperglycemia
- Monitor hydration status: orthostatic BP, I&O, lab values
- Administer IV fluids and electrolyte replacements
pancreatitis: classes of medications
- opioid analgesics
- abx
- histamine receptor antagonists
- PPIs
- pancreatic enzymes
pancreatitis: opioid analgesics
- morphine or hydromorphone
- For acute pain
- Nursing considerations: meperidine is discouraged due to risk of seizures, esp in older adult clients
pancreatitis: abx
- imipenem
- Can be used but are generally indicated for clients who have acute necrotizing pancreatitis
- Nursing Considerations:
- monitor for evidence of infection
- Monitor for seizures
pancreatitis: histamine 2 receptorantagonists
- ranitidine
- Dec gastric acid secretion
- Client edu:
- Take 1 hr before or 1 hr after antacid
pancreatitis: PPI
- omeprazole
- Dec gastric acid secretion
- Nursing considerations:
- Monitor for hypomagnesemia
pancreatitis: pancreatic enzymes
- pancrelipase
- Aid w/ digestion of fats and proteins when taken with meals and snacks
- Nursing considerations:
- Client can sprinkle contents of capsule on nonprotein foods
- Client should drink a full glass of water following pancrelipase
- Clients should wipe lips and rinse mouth after taking (to prevent skin breakdown or irritation)
- Take after antacid or histamine receptor antagonists
- Teach client to take pancrelipase with every meal and snack
pancreatitis: therapeutic procedures
- ERCP to create an opening in the sphincter of Oddi if pancreatitis is caused by gallstones
- Cholecystectomy if pancreatitis is the result of cholecystitis and gallstones
- Sphincterotomy to enlarge the pancreatic duct sphincter
- Endoscopic pancreatic necrosectomy and natural orifice transluminal endoscopic surgery to remove necrotic tissue
- Pancreaticojejunostomy (Roux-en-Y): reroutes drainage of pancreatic secretions into jejunum
chronic pancreatitis due to alcohol use: client edu
- encourage the client to avoid alcohol intake and caffeinated beverages and to participate in support groups for individuals who have alcohol use disorder
pancreatitis: possible complications
- hypovolemia
- pancreatic infection
- type 1 DM
- left lung effusion and atelectasis
- coagulation defects
- multi system organ failure
pancreatitis: complication of hypovolemia
- up to 6 L of fluid can be 3rd spaced, caused by retroperitoneal loss of protein rich fluid from proteolytic digestion
- Client can develop hypovolemic shock
- Nursing actions:
- Monitor for V/S, electrolytes, and for hypoTN and tachycardia
- Provide IV fluid and electrolyte replacement
pancreatitis: complication of pancreatic infection
- Pseudocyst: outside pancreas
- Abscess: inside pancreas
- Cause: leakage of fluid out of damaged pancreatic duct
- Manifestations: fever, epigastric mass, n/v, jaundice
- Nursing actions:
- Monitor for rupture and hemorrhage
- Maintain sump tube if placed for drainage of cyst
- Monitor skin around tube for breakdown secondary to corrosive enzymes
pancreatitis: complication of Type 1 DM
- Cause: lack or absence of insulin due to destruction of pancreatic beta cells
- Nursing actions:
- Monitor blood glucose
- Administer insulin as prescribed
- Client edu:
- Inform the client about long term diabetes mgmt
pancreatitis: complication of left lung effusion and atelectasis
- More common complication in older adults
- Can precipitate pneumonia
- Causes:
- Splinting of chest due to pain upon coughing and deep breathing
- Pancreatic ascites
- Nursing action:
- Monitor for hypoxia
- Provide ventilatory support
pancreatitis: complication of coagulation defects
- DIC
- Causes: release of thromboplastic endotoxins secondary to necrotizing hemorrhagic pancreatitis
- Nursing actions: monitor coagulation studies and for bleeding
pancreatitis: complication of multi system organ failure
- Inflammation of pancreas is believed to trigger systemic inflammation
- Cause: necrotizing hemorrhagic pancreatitis
- Nursing actions:
- Administer tx as prescribed
- Monitor for evidence of organ failure: resp distress, jaundice, oliguria
