Hepatic Flashcards
Cholelithiasis: definition
presence of gallstones in the CBD
Cholelithiasis: Types
- cholestorl: made of undissolved cholesterol and other parts
- pigment: dark brown/black caused by too much bilirubin in bile
Cholelithiasis: Mild clinical manifestations
- sometimes asymptomatic
- feeling of fullness
- abd. distention
- no guarding/ rebound/ fever
- vague RUQ pain; not localized
- pain after fatty meal
Cholelithiasis: Acute biliary colic clinical manifestations
- N/V with heavy meal
- localized pain in RUQ
- guarding/rebounding/ fever
- severe right side abd pain and, radiates to back and right shoulder
- tachycardia/ diaphoresis
- no/hypoactive BS if severe
Cholelithiasis: mild
not completely obstructed, but full contraction is not permitted
Cholelithiasis:: acute biliary colic
complete obstruction of biliary flow
Cholangitis: definition
infection of the biliary duct
Cholangitis: acute
responds to antibiotic treatment
Cholangitis: toxic
may not respond too antibiotics and may require emergency drainage
Cholangitis: open cholecystectomy: definition
removal of the gallbladder
-emptying fo bile into the duodenum directly from liver
Cholangitis: open cholecystectomy: indications
- severe inflammation, infection, necrosis of gallbladder
- blood disorders
- scar tissue from previous surgery
Cholangitis: open cholecystectomy: procedure
- 1-2 hours
- 2-4 days recovery in hospital
Cholangitis: open cholecystectomy: complications
- surgical site pain
- gas, bloating, constipation
- referred shoulder pain
- bile leakage: occur 1-2 after procedure: anorexia, abd pain, N/V, fever
Sphincter of Oddi
- controls flow of pancreatic juices and bile
- morphine causes it to have spasms, should be used in acute pancreatitis of CBD
- meperidine drug of choice
Acute pancreatitis: definition
-inflammation of the pancreas
Acute pancreatitis: clinical manifestations
- severe abd. pain
- back pain
- tenderness
- N/V
- onset of symptoms 24-48 after heavy meal or ETOH
- grey turner’s sign: bleeding in peritoneal cavity
- cullen’s sign: edema around umbilicus
Acute pancreatitis: treatment
- supportive care
- prevent complications
- monitor for sepsis and organ failure
- surgery too risky
- might use gastric decompression
Acute pancreatitis: nursing care
- medications: IV opioids: meperidine
- nonpharmacologic care
- emotional status
- drugs first
Chronic Pancreatitis: definition
- inflammatory disease that is progressive destruction of pancreas
- healthy tissue is replaced by scarred tissue causing pressure in the pancreas to increase
- often seen in ETOH abuse
Chronic Pancreatitis: Clinical manifestations
- recurrent severe abd. and back pain
- vomiting
- weight loss
- steatorrhea
Chronic Pancreatitis: treatment
- pain management with opioids
- avoid ETOH
- surgery if indicated is risky
Liver Age related changes
- reduced drug metabolism along with other age related factors, cause normal drug dosage to be come toxic and require lower dosing
- increased presence of gallstones and decreased gallbladder contract lead to decreased tolerance for fatty food
Hepatic Dysfunction: definition
-damage to hepatocytes decrease ability to respond to injury with healthy tissue
Hepatic Dysfunction: types
- acute
- chronic
- compensated
- decompensated
Hepatic Dysfunction: causes
- cirrhosis: scarring of tissue
- hepatitis: inflammation related to viral hepatiits
- exposure to toxin: environmental, meds, ETOH
- metabolic disorder
- indirectly from CBD obstruction: PHTN
Hepatic Dysfunction: compensated/early clinical manifestations
- mild insufficient clotting: spider angiomas, palmar erythema, unexplained epistaxis (nose bleed)
- visible ascites
- enlarged liver/ abd. pain, edema
- dyspepsia: decreased ability to digest fat
- vitamin deficit/ malnutrition
- portal HTN: splenomegaly
Hepatic Dysfunction: late/decompensated clinical manifestations
- Jaundice
- esophageal varices
- ascites
- splenomegaly
- changes in responsiveness/ hepatic encephalopathy
- spider angiomas
- anemia: coagulation disorders
- palmar erythema
Hepatic Cirrhosis: definition
- chronic and progressive scarification of the lung
- this shrinks lung size and decreases lug functioning
