Liver, Pancreas, & Biliary System Flashcards
(36 cards)
chronic liver disease
damage to liver’s parenchymal cells
causes of chronic liver disease
- bacteria/virus (hepatitis)
- anoxia
- metabolic disorders
- toxins
- medications
- nutritional deficiencies
- hypersensitivity
- malnutrition r/t alcoholism (primary cause)
- diet (non-alcoholic fatty liver disease)
types of jaundice
- hemolytic: due to increased lysis of RBCs; excess bilirubin produced overwhelms normal liver function
- hepatocellular: damaged liver cells can’t clear normal amounts of bilirubin from the blood
- obstructive: bile doesn’t flow normally through the liver or bile duct system to the intestine
cirrhosis
- chronic, progressive disease of liver involving degeneration and destruction of liver parenchymal cells
- acute or chronic
types of cirrhosis
- alcoholic
- postnecrotic
- biliary
etiology of cirrhosis
- alcohol #1 cause
- exposure to certain chemicals
- drug toxicity… acetaminophen
- severe R-sided heart failure (cardiac cirrhosis)
- hepatits B&C
assessment of cirrhosis
- palpation of RUQ
- cirrhosis: liver enlarged, and later small/hard, nontender
- acute hepatitis: liver soft, tender, easily movable
cirrhosis labs
- clotting studies: PTT, PT, INR
- AST or SGOT; ALT or SGPT; GGT and GGT and GGTP
- serum pigment studies: bilirubin, total & direct, urine bilirubin, urine and fecal urobilinogen
- serum ammonia
- serum proteins: total protein, serum albumin, serum globulin, serum electrophoresis
radiologic tests for cirrhosis
- CT/US
- abdominal x-ray
- liver scan
- barium study of esophagus
post-op nursing interventions for liver biopsy
- assist pt to lie on right side with pillow under costal margin
- immobilize for several hours in this position
- discourage coughing or straining
- VS q 15 minutes for first hour; then q 30 minutes for the next 2 hours
- watch for s/s of hemorrhage
laparascopy
direct visualization by scope of the liver surface and gallbladder
manifestations of early stages (compensated) of cirrhosis
- GI disturbances: anorexia, dyspepsia, flatulence, N/V
- RUQ dull abdominal pain
- lassitude
- slight weight loss
- hepatomegaly and splenomegaly
- abdominal pain
- ankle edema
- firm, enlarged liver
- intermittent mild fever
- palmar erythema (reddened palms)
- unexplained epistaxis
- vague morning indigestion
- vascular spiders
manifestations of later stages (decompensated) of cirrhosis
- Ascites
- Clubbing of fingers
- Continuous mild fever
- Epistaxis
- Gonadal atrophy
- Hypotension
- Jaundice
- Muscle wasting
- Purpura (due to decreased platelet count)
- Sparse body hair
- Spontaneous bruising
- Weakness
- Weight loss
- White nails
complications of cirrhosis
- portal htn
- esophageal/gastric varices
- peripheral edema (usually ankle)
- ascites
- hepatic encephalopathy and coma
portal htn
- portal/hepatic veins damaged causing obstruction of blood flow in portal system resulting htn
- results in: increased venous pressure in portal circulation, splenomegaly, large collateral veins, ascites, systemic htn, gastric/esophageal varices
esophageal/gastric varices
- tortuous veins that are enlarged and swollen due to portal htn
- quite fragile and intolerant high pressure
- easily ruptured, causing slow oozing or massive hemorrhage
- must assess for bleeding- melena, hematemesis
treatment of esophageal/gastric varices
- avoid ETOH, ASA, NSAIDS, irritating foods
- control coughing
- IV fluids, blood replacement prn
treatment of esophageal/gastric varices if bleeding
- stabilize patient/maintain airway
- iv fluids/blood products
- drug therapy
- endoscopic sclerotherapy
- endoscopic ligation
- ballon tamponade
- shunting procedures
treatment of ascites
- sodium restriction (depends on degree of ascites, watch for malnutrition)
- diuretics
- fluid removal (paracentesis, TIPS procedure)
hepatic encephalopathy and coma
- life threatening complication of liver disease r/t accumulation of ammonia and other toxic metabolytes in the blood
- liver is unable to convert ammonia to urea to be excreted by the kidneys
- ammonia crosses blood-brain barrier and causes neurotoxic effects
- can have gradual or sudden onset and can range from mild sleep disturbances to severe coma
- earliest sign: minor mental changes and motor disturbances
treatment of hepatic encephalopathy and coma
- lactulose (cephulac): prevents ammonia from passing from colon to blood
- metronidazole, vancomycin, rifaximin: reduce bacterial flora of colon
- diet for cirrhosis: high CHO, high calories, low fat, normal protein intake, low Na
cirrhosis nursing interventions
- hemorrhage
- hepatic encephalopathy
- ascites/ anasacra
- jaundice/pruritis
- vitamin deficiency
- metabolic abnormalities (drug metabolism)
- diet
- addiction
fulminant hepatic failure
- acute liver failure
- rapid onset of severe liver dsyfunction with no prior history of liver disease
- associated with hepatic encephalopathy
common causes of fulminant hepatic failure
- acetaminophen with ETOH
- nsaids
- sulfa drugs
