Q

Liver Age related changes

A
  • reduced drug metabolism along with other age related factors, cause normal drug dosage to be come toxic and require lower dosing

25
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
26
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
27
Hepatic Dysfunction: late/decompensated clinical manifestations
- Jaundice - esophageal varices - ascites - splenomegaly - changes in responsiveness/ hepatic encephalopathy - spider angiomas - anemia: coagulation disorders - palmar erythema
28
Hepatic Cirrhosis: definition
- chronic and progressive scarification of the lung | - this shrinks lung size and decreases lug functioning
29
Hepatic Cirrhosis: types
- alcoholic: scarring around portal areas - post-necrotic: scarring after viral hepatitis - biliary: scarring after CBD obstruction or cholelangitis
30
liver function test
- AST/ALT: increase with abnormal liver function - GGT: increase with ETOH liver disease - Serum bilirubin/urobilnogen or fecal/urine urobilnogen: associated with jaundice - Alk phos. measure biliary obstruction - PT: increase with time to clot - ammonia - serum albumin and protein
31
Major complication of liver disease
- jaundice - Portal HTN - hepatic encephalopathy - ascites - esophageal varices
32
Hepatic Encephalopathy: definition
life threatening consequence of advanced liver disease -liver's decreased ability to detoxify by products of metabolism like ammonia cause ammonia build up. Ammonia gets pushed out into blood circulation
33
Hepatic Encephalopathy: early/compensated clinical manifestations
- mild mental status changes: slight confusion, sleeping patterns, restless - spider angiomas - motor disturbances: asterixis, deep tendon reflex, difficulty writing, - hepaticas: sweet breath
34
Hepatic Encephalopathy: end/ decompensated clinical manifestations
- severe failure to make protein, clotting factors, and increase portal hypotension - insuffienct clotting factors: purpura, bruising, epistaxis, anemia - malnutrition: muscle wasting, sparse body hair, wight loss - Portal HTN: splenomegaly, esophageal varies - ascites - grey stool - mental deterioration - dyspepsia: decreased ability to digest fatty food
35
Hepatic Encephalopathy: progressive worsening
Mental status: sleepier, somnolent, coma | -motor: flaccid extremities, no deep tendon reflex
36
Hepatic Encephalopathy: treatment
- lactulose (chronulac): decrease pH of bowel and ammonia production to increase BM. - Neomycin: inhibit protein synthesis in bowl and decrease ammonia production - avoid: narcotics, sedatives, barbiturates - protein restriction and nutritional support - prevent complications of immobility - symptom management - promote rest: decreased demon and give liver more blood - No ETOH or raw shellfish: Hep A risk - early detection of bleeding: prevent hemorrhage - skin care: itching - early detection of decreasing mental jsatuts: reduce risk of injury
37
Hepatic Encephalopathy: diagnosis
- Labs: decrease albumin and increase in: globulin, all. phos., AST/ALT, GGT, bilirubin, PT - UGI x ray - CT scan - Liver US - EGD - Liver biopsy: confirmation
38
Liver biopsy considerations
- remove piece of liver - pre: take PPT - during: hold breath at end of expiration - post: lay on right side with pillow under to tamponade bleeding and bile leakage and frequent VS for bleeding risk
39
Jaundice: definition
yellowing of sclera, skin, mucous membranes when bilirubin exceed 2.5 mg/dL
40
Jaundice: Types
- Hemolytic: increased destruction of RBC - Hepatocellular: hepatocytes can not get rid of bilirubin fast enough - Obstructive: bilirubin does not enter small intestine
41
Jaundice: Hepatocellular clinical manifestations
- N/V - loss of appetite - headaches - chills - fever: if infection - fatigue - increased bilirubin, AST/ALT, urine urobilinogen
42
Jaundice: Obstructive clinical manifestations
- dark, orange, foamy urine - clay colored stools - dyspepsia - pruritis - increase bilirubin and all. phos.
43
Portal HTN: definition
-liver damaged cause high blood pressure in the portal system. this causes albumin to leak out of the system leading to ascites. It also leads to enlarged veins around the body
44
Portal HTN: clinical manifestation
- esophageal varices - caput medusae - ascites marked - hemorrhoid - hypersplenism: moderate anemia, neutropenia, thrombocytopenia - mechanical obstruction
45
Ascites: definition
increased portal HTN causes vasodilation of the abdominal circulation that leads to decreases in ECF and appears of ascites. Lier function decline leads to decreased metabolism of aldosterone which stimulates the RAAS system to increase sodium and water retention to intravascular systemic, which is then pushed back out of the ECF
46
Ascites: clinical manifestation
increased abdominal firth: measure daily - weight gain - dyspnea - striae and distended viens - fluid electrolyte imbalance
47
Ascites: treatment
goal: reduce fluid retention - low sodium diet - diuretics: aldactone - daily weights: should not lose 1-2kg/day - bedrest: upright too much pressure on renal system - paracentesis - IV salt porr albumin - TIPS
48
paracentesis
removed 5-6L - pre: empty bladder - during: VS and tolerance, upright - post: infection, hypovolemia (changes in MS), Hematuria, leaking at puncture sire
49
Esophagael varices: definition
increase pressure of portal system leads to blood back up in the esophagus veins
50
Esophagael varices: factors related to
- exertion - coughing/sneezing - straining to defecate - reflux and vomiting - salicylate
51
Esophagael varices: symptoms
- hematemesis - melena - hemorrhoids
52
Esophagael varices: complications
- hemorrhage: if ruptured | - made worse by liver inability to clot
53
Esophagael varices: treatment
- endoscopic sclerotherapy: inject scarring agent to vein to constrict or eliminate vien - esophageal banding: stop use of vein
54
Hepatitis: definition
- toxin or drug induced has better recovery (Tylenol) | - systemic viral infection that causes necrosis and inflammation of liver
55
Hepatitis: types
-A, B, C, D, E, G
56
Hepatitis: Stages: prodromal/preicteric
- nonspecific flu like symptoms - malaise - fatigue - headache - myaglis - anorexia - N/V/D
57
Hepatitis : Stages: icteric
- jaundice - dark urine - clay stools - steatorrhea - pruritus - large tender liver - increased liver enzymes
58
Hepatitis: stages: posticteric
- convasclent stage - decrease of fatigue - decrease jaundice - increase appetite
59
Hepatitis: acute
-History of Iv drug use, Hepatitis, HIV -poor appetite -N/V fever -sever RUQ pain -GI baled -confusion -bruising -dizziness -dark urine, clay colored stools -steatorrhea -flu like
60
Hepatitis A: defintion
- non chronic - fecal-oral route - poor sanitation/ contaminated water
61
Hepatitis A: clinical manifestation
flu like - malaise - fever - jaundice - urine - indigestion - enlarged liver and spleen
62
Hepatitis A: prevention
- hand-washing | - Hep A vaccine or globulin 2 weeks after exposure
63
Hepatitis A: diagnosis
stool specimen
64
Hepatitis A: treatment
- bedrest during acute stage | - nutritional support
65
Hepatitis B: definition
- chronic | - parenteral/sexual
66
Hepatitis B: clinical manifestations
flu like - malaise - fever - jaundice - urine - indigestion - enlarged liver and spleen
67
Hepatitis B: prevention
- Hep B vaccine | - Globulin is allegory to vaccine: cannot take right after Hep B vaccine, will cancer out effects
68
Hepatitis B: treatment
- Meds - bedrest - nutrition
