Hepatitis Liver Cancer Liver Transplantation NCLEX Time

3 Gallbladder Function- storage depot for bile
Cholecystitis- inflammation of the gallbladder wall, acute infection Cholelithiasis- presence of gallstones When food enters the duodenum, the gallbladder contracts and the sphicter of Oddi relaxes (valve in the common bile duct), allowing bile to enter the intestine. Cholecystitis- inflammation of gallbladder usually develops in assoc. with gallstones. But can occur from bacterial invasion or biliary spasm. Jaundice, bile obstruction not common. Blockage of bile flow from GB Gallbladder becomes fibrotic and contracted, which result in decreased motility and deficient absorption. 3x4” pear shaped hollow organ underside of liver Cholelithiasis- over time the concentration of bile in the gallbladder may result in insoluble stones, especially if bile contains high amounts of cholesterol. Result of abnormal metabolism of bile salts and cholesterol Over 20 million americans have G.B. disease, many have surgery within 1 year of diagnosis. Female, Fat and Forty- many get gall bladder problems. Cholesterol stones form and block drainage of bile from gallbladder, which causes spasm, GB becomes inflamed, edematous and distended. This congestion leads to changes in GB circulation which eventually causes necrosis. Bacterial growth also develops.

4 Cholecystitis:Pathophysiology
The most common cause is cholelithiasis; obstructing the cystic and or common bile ducts. Can be acute or chronic Bile is used for digestion of fats. It’s produced in the liver and stored in the gallbladder. Acute- gallstones partially/completely obstruct CBD Chronic Cholecystitis- results from inefficient emptying of bile by gallbladder and gallbladder muscle wall disease persists. Chronic- may be caused by or lead to formation of gallstones (cholelithiasis) The most common cause is cholelithiasis obstructing the cystic and or common bile ducts. (Bile flow from the gallbladder to the duodenumThe most common cause is cholelithiasis obstructing the cystic and or common bile ducts. (Bile flow from the gallbladder to the duodenum)

5 Gallbladder Pancreatitis and Cholangitis (inflammation of common bile duct) can occur as complications of cholecystitis. Pancreatitis and cholangitis result from backup of bile throughout biliary tract. Bile obstruction leads to jaundice. Nonsurgical management- diet and drug therapy. Jaundice- yello discoloration of skin and mucus membranes and icterus= yellow discoloration of sclera can occur in clients with acute cholecystitis, but is most commonly seen in clients with chronic gallbladder inflammation . Impeded or obstructed flow caused be edema of ducts or gallstones contributes to extrahepatic obstructive jaundice. Jaundice in cholecystitis may also be caused by direct liver involvement. The inflammation of the liver’s bile channels or bile ducts may cause intrahepatic obstructive jaundice, resulting in an increase in circulating levels of bilirubin, the principal pigment of bile. When the concentration of bilirubin in the blood increases to greater than 2mg/dl, jaundice occurs. Excessive bile salts accumulate on the skin causing pruritis (itching) or a burning sensation. In a person with obstructive jaundice, the normal flow of bile into duodenum is blocked. Bilirubin is unable to reach the large intestine, where it is converted to urobilinogen- which accounts for the normal brown color of stool, clay – colored feces results. Water soluble bilirubin is normally excreted by kidneys in urine, when an excess in circulating bilirubin occurs, the urine becomes dark and foamy because of the kiney’s efforts to clear the bilirubin. Chenodiol- blocks liver synthesis of cholesterol, decreases biliary cholesterol levels leading to gradual dissolving of floating cholesterol gallstones.

6 Risk Factors More common in females (Remember 4Fs) High-fat diets
Obesity (impaired fat metabolism, high cholesterol) Genetic predisposition Older than 60 years Type 1 diabetes (high triglycerides) Low-calorie, liquid protein diets Rapid weight loss (increases cholesterol) Trauma, Surgery, Immobilty Pregnancy HRT Fat, fertile, Female,

7 Diagnostic Procedures
RUQ ultrasound Abdominal x-ray- calcified gallstones ERCP- Endoscopic Retrograde Cholangiopancreatography Hepatobiliary scan (assesses patency of biliary duct system Elevated WBC Increase serum bilirubin levels Increased LFTS; AST, ALT, Alkphos, LDH Serum cholesterol elevated above 200 mg/dL ultrasound visualizes gallbladder edema Elevated WBC indicates inflammation AST- aspartate aminotransferase (recheck labs) ALT- LDH- lactate dehydrogenase ERCP- Endoscopic Retrograde Cholangio Pancreatopography.- Direct visualization of biliary tree via endoscope passed through sphicter of Oddi: CBD, pancreatic and hepatic ducts can be visualized. Stone retrieval also possible.

8 Nursing Assessment S/S of Acute Cholecystitis
Patient complains of sharp RUQ pain radiating to right shoulder Intense pain after eating a high fat meal Increased HR, pallor, diaphoresis Rebound tenderness Nausea, vomiting, anorexia Dyspepsia, eructation, and flatulence Fever, chills Steatorrhea, light colored stools Light colored bowel movements Fat soluble vitamin deficiency With obstructive jaundice, bilirubin can’t reach large intestines where it is converted to urobilinogen- which accounts for normal brown color of stool. Water soluble bilirubin is normally excreted by kidneys as urine, when an excess of circulating bilirubin occurs, the urine becomes dark and foamy because of the kidney’s efforts to clear the bilirubin. Familial tendency for cholelithiasis Bile is needed for absorption of fats/fat soluble vitamins in intestines

9 Nursing Diagnoses Acute Cholecystitis
Acute pain Impaired gas exchange Risk for infection Knowledge deficit

10 Cholecystitis Diet therapy: NPO or modify diet by avoiding high fat or high volume meals. These measures decrease stimulation of gallbladder. IV Hydration Drug therapy: Acute pain: opioids: meperidine HCL (Demerol), not Morphine Sulfate Antispasmodics or anticholinergics: Atropine or dicyclomine (Bentyl) Anti-emetics Antispasmodics- relax smooth muscles preventing biliary contraction , minimizes sevretions and assists in reduction of apin. Antiemetics such as tigan are also ordered. MSO4 causes biliary spasm and constrict the sphinctor of Oddi

11 Surgical Interventions
Open Choleycystectomy Laproscopic Cholecystectomy Laparoscopic- Ambulatory surgery, usual pre op tests and pt. NPO. Dr. make a 10mm midline puncture at the umbilicus. The abdominal cavity is insufflated with 3-4 L Co2 A trocar catheter is inserted, through which a laparoscope is infused.This is attached to a video camera. The surgeon makes3 small punctures through which to intoduce laparoscopic forceps to manipulate the gallbladder. A laser is used to dissect the gallbladder away from the liver bed and to close off the cystic artery and duct. The surgeon extracts the gallbladder through midline puncture site. Traditional surgery- not used very often any more. Subcostal incision removes gallbladder, explores ducts and inserts a t-tubedrain to ensure patency of duct.

12 Nursing Interventions S/P Cholecystectomy
Lap vs.Open Cholecystecomy LOC Vital signs Pulmonary Hygiene (cough deep breath, ambulate, turn and postion incentive spirometer) Splinting to reduce pain Pain management Monitor wound incision /S/S of infection Monitor T-tube drainage (initially bloody, then green-brown bile) T-tube initially may drain >400ml/day then should gradually decrease Advantages??

13 Care of the T-tube Report sudden increases in drainage or amounts exceeding 1000ml/day Keep drainage bag below level of GB Inspect surrounding skin Maintain flow by gravity Never irrigate, clamp or aspirate without MD order Clamp 1 to 2 hours ac and pc Monitor and document the client’s response to food Normal darinage is about 400ml pe r day Assess drainage- serous to green bilious liquid by 2-3rd postop day, gradually decrease in amt After several days of drainage, the tube may be clamped for an hour befora and after meals to deliver bile to the duodenum to aid in digestion Change dsg QD

14 Nursing Interventions: Patient Education
Dietary counseling: Low fat diet Weight reduction Fat-soluble vitamins and bile salts to enhance absorptions and aid digestion Avoid gas-forming foods Smaller more frequent meals Activity precautions 4-6 weeks Care of T-tube

15 Pancreatitis and Pancreatic Cancer

16 Function of Pancreas Pancreas has both exocrine and endocrine functions Exocrine: secretes pancreatic enzymes to break down starch, proteins, and fats Endocrine function: Islet of Langerhans: B cells secrete insulin and A cells secrete glucagon What’s the difference? The pancreas is a long, slender gland lying behind the stomach and in front of the first and second lumbar vertebrae. It consists of the head, body and tail. The anterior surfaces covered by the peritoneum. The pancreas contains both lobes and lobules. The pancreatic duct extends along the gland and enters the duodenum through the common bile duct. Exocrine- term applied to glands whose secretion reaches an epithelial surface either directly or through a duct. It is the exocrine function of the pancreas that contributes to the process of digestion. Early activiation of these enzymes in the pancreas cause inflammation: lipase, trypsin, elastase. Amylase, Endocrine glans secrete products into EC space and pass through membranes into blood eg. hormones Exocrine glands-eg digestive enzymes,, sweat glands, sebaceous glands

17 Pathophysiology Pancreatitis is an autodigestion of the pancreas
Can result in inflammation, necrosis, and hemorrhage Acute pancreatitis is an inflammation of the pancreas resulting from activated pancreatic enzymes autodigesting the pancreas Severity varies but the overall mortality rate is 10% to 20% r/t hypotension, fluid/electrolyte imbalance, and shock Chronic pancreatitis progressive destruction of the pancreas. Mortality rate up to 50% Pancreatitis is an inflammatory process of pancreas, resulting in autodigestion of organ by its own enzymes. Ranges from mild to severe, severe form of pancreatitis is characterized by diffusely bleeding pancreatic tissue, fibrosis and death. Mortality is 10% due to hypotension, fluid/lyte imbalance and shock. Lipolysis- fatty acids are released and combine with calcium and cause hypocalcemia. Necrosis of blood vessels can occur- leads to generalized hemorrhaging, which can lead to shock and death. Complications- Jaundice- occur from swelling of head of pancreas which impedes blood flow through common ile duct. Transient hyperglycemia- from release of glucagon and decreased release of insulin from damage to islet cells. Pleural effusion- enzymes from peritoneal cavity go to pleural cavity via lymph channels, atelectasis and pneumonia can occur.

18 Digestive enzymes for starch, protein, and fat Endocrine function:
What would you expect to see if the pancreas isn’t functioning properly?? Exocrine function: Digestive enzymes for starch, protein, and fat Endocrine function: Insulin and glucagon Transient hyperglycemia Mid epigastric pain

19 Diagnostic Testing for Pancreatitis
Elevated serum amylase, lipase, elastase Elevated trypsin Elevated urine amylase Elevated serum glucose Serum calcium and magnesium levels are decreased Serum liver enzymes and bilirubin levels are elevated- hepatobiliary involvement WBC elevated CT scan with contrast Several theories explain the triggering mechanisms leading to enzyme release p.1404 Iggy Rises in enzymes means pancreatic cell injury Glu= pancreatic cell injury, CHO metabolism impaired, decreased insulin release

20 Nursing Assessment Monitor mental status
Monitor VS- Elevated T, P. R, decreased BP. Dyspnea, or resp. complications Sudden onset of severe pain Epigastric pain radiating to back, left flank, or shoulder Not relieved with vomiting Some relief in fetal position Abdominal tenderness, guarding, rigidity. Palpable mass if cyst is present Possible changes in behavior r/t ETOH withdrawal. Pain may be relieved in fetal position, Worse when lying down or with eating Pleural effusions, atelectasis, PN Pain is intense and continuous. Pain is in mid-epigastrum. Frequently acute in onset(24 to 48 hrs. after heavy meal or alcohol ingestion. May be more severe after meals and unrelieved by antacids. May be accompained by abd. Distension. Pt. appears acutely ill. Board like abdo., soft without peritonitis Ecchymosis in flank or around umbilicus, which may indicate severe hemorrhagic pancreatitis. n/v, fever jaundice, mental confusion, agitation. Hypotension related to hypovolemia and shock. Acute renal failure common. May develop tachycardia, cyanosis and cold, clammy skin. Resp. distress and hypoxia. Dyspnea, tachypnea, abnormal blood gas values. Diffuse pulmonary infiltrates.Hypocalcemia, hyperglycemia and DIC Dx- based on history of abd. Pain, known risk factors and elevated serum lipase and amylase, most indicative.

21 Nursing Assessment Nausea and vomiting Weight loss
Signs and symptoms of inflammation or peritonitis Ecchymosis on the flanks (Turner’s sign) Bluish periumbilical discoloration (Cullen’s sign) Generalized jaundice Paralytic ilieus Hyperglycemia

22 Nursing Diagnoses Pain r/t Fluid volume deficit r/t
Altered nutrition r/t Ineffective breathing pattern r/t

23 Pancreatitis Nursing Interventions
P- Pain: Morphine or Dilaudid A- Antispasmodic drugs motility N- NPO/NGT suction- pancreas to rest, TPN C- Calcium, hypocalcemia, replace Ca R- Replace F/E- NG losses and fluid shift E- Endocrine & Enzymes A- Antibiotics- with fever S- Steroids- corticosteroids during acute attacks C- Calcium- monitor levels and look for clinical signs, replace as needed. R- Replace Fand E- NG losses plus- fluid shifts into peritoneum. TPN if NPO over 7-10 days 3. Medications administered Pancreatic enzymes: pancreatic and panrelipase take with meals for fat and protein digestion Education: take ac or c meals, swallow wihout chewing to minimize oral irritation, mix powder forms in applesauce or fruit e in protein containing foods. Wipe lips to avoid skin irritation Anticholinergics,glucagon,histamine inhibitors- all decreas vagal stimulation, decrease GI motility and inhibit pancreatic secretions E- Endocrine- control of hyperglycemia- insulin, glucagon, calcitonin and somatastatin sometimes used. Other interventions may include heparin, peritoneal dialysis to remove toxic substancesand peritoneal tap for fluid collection which impairs resp. dynamics no oral intake to inhibit pancreatic stimulation Anticholinergics- atropine (Bentyl) Vitamin supplements Monitor blood glucose levels and administer insulin as needed Monitor hydration levels orthostatic blood pressure, I&O, lab values, weights morphine sulfate is not used: can cause spasms in the pancreas(spincter of Oddi)

24 Pancreatitis Nursing Interventions
Monitor for hypocalcemia: Tetany Trousseau’s sign (hand spasm when BP cuff is inflated) Chvostek’s sign (facial twitching when facial nerve is tapped) Tetany: A combination of signs and symptoms, due usually to low calcium, that can include:

25 Complications of Pancreatitis
Pancreatic Infection: Pseudocyst or Abscess Type 1 diabetes Left lung effusion and atelectasis DIC- Monitor bleeding times Acute Renal Failure ARDS- Shock Paralytic Ileus ** Pulmonary failure accounts for more than 50% of the deaths that occur within the first 7 days of the disease ARDS, pulmonary failure accounts for half of all deaths within 7 days of disease. DIC- hypercoagulation of blod, development of microthrombi. Shock- peripheral vasodialtion, from vasoactive substances. Acute renal failure- in response to hypovolemia. Paralytic ileus- from release of pancreatic enzymes into abdominal cavity.

26 Chronic Pancreatitis Types: 1.Chronic Calcifying Pancreatitis (CCP)
2.Chronic Obstructive Pancreatitis- develops from inflammation, spasm and obstruction of sphincter of Oddi. The primary cause of chronic pancreatitis in the older adult is chronic alcoholism Age related changes reduce the older person’s ability to process alcohol Psychosocial interventions? Progressive, destructive disease, remissions and exacerbations Goals: relief of pain, prevention of recurrence of attacks, prevention of complications and nutritional support S&S , TX similar to acute with inclusion of pancreatic enzymes replacemnet Risk factor for pancreatic cancer Chronic- progressive, destructive disease of pancreas, characterized by remission and exacerbations (recurrence). This may develop after repeated episodes of alcohol induced pancreatitis. CCP alcohol induced- protein precipitates and plug ducts and leads to obstruction, cell replacement and ulceration. Pathophysiologic changes- loss exocrine function decreased secretion of aqueous bicarb and enzymes. Aqueous component- neutralizes duodenal contents and pancreatic enzymes that are essential to normal digestion and absorption. When pancreatic enzyme secretion is reduced more than 8%, malabsorption of fats occurs- steatorrhea, pale, bulky, frothy, stools with an offensive odor. This malabsorption of fats also leads to wt. loss, muscle wasting and general debilitation. Loss of endocrine function- diabetes. Pulmonary complications- effusion and infiltrates. ARDS may develop. Loss of exocrine function

27 Pancreatic Cancer Vague symptoms
Usually diagnosed in late stages after liver or gallbladder problems Cause is unknown Occurs years of age Risk factors 30k case/year= to # die yearly <20% survive longer that 1 year <5% survive for 5 years because occult malignancy, hidden

28 Diagnostic Procedures
Serum amylase and lipase elevated Serum alkaline phosphate and bilirubin levels elevated CEA (Carcinoembryonic antigen elevated) CT ERCP: Most definitive test, analysis of aspirate, placement of a drain or stent for biliary drainage Abdominal paracentesis: Test for malignant cells Nursing interventions for paracentesis; consent, specimen to lab, assess/monitor insertion site

29 Nursing Assessment Pancreatic Cancer
Monitor vital signs Monitor for signs of biliary obstruction (Jaundice-late sign, clay colored stools and dark urine-earlier sign) Nursing Diagnoses….. Chemotherapy: Monitor for myelosuppression and pancytopenia Radiation: Monitor fatigue and diarrhea Anorexia and weight loss Prep for possible surgery The liver releases bile salts into the stool, giving it a normal brown color. You may have clay-colored stools if you have a liver infection or if the flow of bile out of the liver is blocked. Yellow skin (jaundice) often accompanies clay-colored stools. NSG DX- Acute Pain Imbalance Nutrition: Less than body requirements

30 Surgical Procedures Whipple procedure:
Removal of the head of the pancreas, duodenum, parts of the jejunum and stomach, gallbladder, and possibly the spleen The pancreatic duct is connected to the common bile duct and the stomach is connected to the jejunum Post-op care Extensive procedure- radical pancreaticoduodectomyPrevent complications: CV, Pulm, GI wound, Metabolic (Unstable DM, Renal failure)

31 Postoperative Care Whipple Surgery
LOC Vital signs Respiratory status: Incentive spirometer, O2 IVF Pain Management : PCA Opioids Monitor NG -tube Surgical drainage: Protect the surgical sites Semi-fowlers: facilitate lung expansion and to decrease stress on the suture line Monitor glucose levels and administer insulin prn Provide nutritional support Standard post-op care for GI surgery facilitate lung expansion and to decrease stress on the suture line

32 Complications Whipple Procedure
1.Fistulas Due to breakdown of a site of anastomosis 2.Peritonitis Internal leakage of corrosive pancreatic fluid Elevated WBCs, fever, abdominal pain, rebound tenderness, alteration in bowel sounds, shoulder pain Administer antibiotics 3. Venous thromboembolism: most common complication of pancreatic cancer Monitor pulses and for areas of warmth and tenderness Administer anticoagulants Venous compression

33 LIVER DISORDERS HEPATITIS CIRRHOSIS OF THE LIVER LIVER CANCER
TRANSPLANTATION

34 Functions of the Liver 1.Bile production: essential for fat metabolism
2.Protein metabolism: Breaks down amino acids ammonia urea excreted via kidneys 3.Phagocyte system: removes toxins and breaks down old RBCs Kupffer cells remove bacteria and toxins Liver is a very large and vascular organ The portal circulatory system bringd blood to the liver from the stomsch. Intestines, spleen and pancreas

35 Functions of the Liver 4.Synthesizes albumin
5.CHO Metabolism: storage of glycogen 6.Storage of fat soluble vitamins A,D,E,K 7.Steroid and drug metabolism 8.Clotting: prothrombin and fibrinogen Vit K can’t be absorbed due to decrease synthesis of bile fats in the liver. Without Vit K, clotting factors 2,7,9, and 10 are not produced in sufficient quantities, bleeding and bruising occurs. Many drugs are metabolized by liver: barbs, opioids, sedatives, amphetamines Liver dysfunction- What symptoms would you expect to see? What symptoms would you expect to see? Clotting factors Infection Swelling: decreased albumin levels Vitamin deficits Digestive problems Unable to rid body of toxins Blood flow problems/portal vein Increased bilirubin

36 Lab Findings in Liver Disease
Elevated AST(aspartase aminotransferase) Elevated ALT (alanine aminotransferase) Elevated LDH (lactate dehydrogenase) and ALP (alkaline phosphatase) Elevated serum bilirubin Increased total serum protein-acute Decreased total serum protein- chronic Decreased serum albumin (normal 3-5 g/dl) Prolonged PT/INR Elevated serum ammonia INR>2

37 Liver Lab Results LAB TESTS NORMAL RESULTS LIVER DISEASE AST 5-40 u/L
ALT 8-20 u/L LDH units/L Alkaline Phosphatase u/L Bilirubin mg/dl Total Protein g/dl Normal Ammonia 15-45 mg/dl PT seconds Prolonged INR Albumin 3-5 g/dl

38 Viral Hepatitis-Facts
Acute (short- term)-inflammation of the liver Chronic (long- term) debilitating with increasing severity of symptoms Each year 250,000 in US become infected Persons with hepatitis are carriers and can spread disease without showing any symptoms of the disease Never donate blood, body organs or tissues Hepatitis B vaccine for all health care workers Mandated that all cases of hepatitis are reported to the health department Hepatitis A vaccine for high risk population Several types- all Inflammation of the liver

39 High Risk Behaviors HBV, HCV
Failure to follow Universal/Standard Precautions Dirty needles, sharp instruments, body piercing, tattooing, sharing drug paraphernalia and personal hygiene tools Unprotected sex, multiple sex partners and/or anal sex Unscreened blood transfusions (before 1992) Hemodialysis Poor hand hygiene with food preparation by a person infected with hepatitis Traveling in underdeveloped countries and using tap water Living in crowded environments: prisons, dormatories, universities, long-term care facilities, military housing Chronic HCV or chronic HBV leading cause of ESLD and most common and leading reason for transplantation in US

40 Type Route of Transmission Risk Factors HAV Oral-fecal route
Ingestion of contaminated food (shellfish) or water HBV Blood Drug abuse Sexual contact Healthcare work HCV HDV Co-infection with HBV HEV Contaminated water A- GI distress, flu like Run its course B Anorexia, NV, Fever, fatigue, RUQ pain, Dk urine, light stool, joint pain, jaundice C Asymtomatic for yrs until blod test is done or liver impairment signs appear, similar to B D Often asymptomatic, coinfects with HBV, trnasmitted parenterally E Resembles A Chronic hep- inflammation longer than 6mos. Usually occurs with B or C. Liver bx for dx. Increases risk for liver Ca

41 Diagnostic testing Serological markers: Identify presence of virus. +HBsAg for longer than six months indicates chronic hepatitis and/or hepatitis carrier status Clotting factors Hepatitis antibody serum test: Indicates immunity and effectiveness of vaccine ( + HBsAb) X-rays : hepatomegaly, ascites, spleen enlargement Liver biopsy: Most definitive test that identifies the degree of liver damage Nursing: consent, explain procedure, have patient lie on affected surgical side for short period of time after biopsy) HBsAg- Considered infectious as long as present in blood HBsAb- shows recovery and immunity to hepatitis B (after immunization) Liver bx- done in ASU percutaneously if no clotting issues.

42 Nursing Assessment Hepatitis
Monitor for signs and symptoms: Flu-like symptoms and RUQ abdominal pain, N&V HBV presents with hepatomegaly and possible obstruction Signs of obstruction: light colored stools, dark urine, jaundice, elevated bilirubin and liver enzymes Flu-like symptoms (headache, fatigue, low grade fever, RUQ abdominal pain, nausea and vomiting

43 Nursing Assessment Hepatitis
Assess skin color and sclera Pain in muscles joints and abdomen Fever, malaise, increased fatigue, nausea and vomiting Clay colored stools Dark urine Rashes, pruritis

44 Hepatitis A Mild course, spread fecal-oral route Sources: Contaminated water Shellfish from contaminated water Infected food handlers Oral/anal sex Incubation: days Symptoms: Most common type Hepatitis A vaccine recommended for hi risk pts: travel abroad, health care workers, food handlers where HAV is high. Ig is given immediately after exposure Lifetime immunity with 2 doses. Most HAV is killed by disinfectants S&S mild, flu like URI, LGT Anorexia Symptoms clear, but pt may have residual liver damage. Symptoms may subside in 3-7 days

45 Hepatitis B HBV spread by percutaneous/permucosal route by contamination with blood or serous fluid. Incubation days Sources: sexual contact,sharing needles, tattooing, body piercing, accupuncture, perinatal Symptoms: Nurses and other health care workers vaccinated Infants vaccinated Can’t give blood until 1 year p tattoing, piercing Symptoms: similar to other viral syndromes, malaise, nausea, abdominal discomfort, icterus, dark urine, enlarged tender liver, possible jaundice Can progress to fulminant- mortality 80%

46 Hepatitis- Other Causes
Direct toxic hepatitis- alcohol abuse, tylenol toxicity, industrial toxins Idiosyncratic toxic hepatitis- may occur during or shortly after exposure to drug Eg. Halothane, Methyldopa, Isoniazid Toxic hep- results in necrosis and fatty infiltration of liver. Industrial toxins ( carbon tetrachloride) have a direct toxic effect on liver Idiosncratic- produces changes similar to thiose found in viral hepatitis Complication- necrosis

47 Nursing Interventions
Medications: Used sparingly to promote hepatic rest Antivirals- Lamivudine (Epivir HBV) Interferon for HBV and HCV Assess for side effects of interferon: Flu-like symptoms Alopecia Bone marrow suppression Monitor CBC Administer antiemetics Provide comfort measures Immunomodulating drug Blocks virus from replicating, renal toxicity Antiemetics- tigan and dramaimine ok, compazine not. Check all meds for liver toxicity Antivirals- SE myopathy, muscle weakness and aching

48 Nursing Interventions
Contact Precautions Hepatitis A,E Universal/Standard Precautions for HBV,HCV ,HDV Limit activity: bedrest, initially to promote hepatic healing Patient Education Dietary Education: High carbohydrate, high calorie, low-moderate fat, low-moderate protein WHY? Teach good personal hygiene, safe practices for preparing and dispensing foods Mandatory reporting of viral hepatitis to health dept Goal- patient will gradually increase activity to prior level Rest promotes healing of liver Void fatty or fried foods- increases nausea Small frequent meals to promote nutrition and healing Meds used sparingly for hepatic rest and regeneration of tissue Disease transmission and exposure and transmission Hepatitis vaccine Universal/Standard Precautions Needleless systems Handwashing! Traveling: drink bottled water in underdeveloped countriesNo alcohol, no OTC meds for 3-12mos Avoid sex until antibody testing results are negative Hep A- do not prepare food for others Supplemental vitamins

49 Complications Chronic hepatitis B, C, D: increases risk for liver cancer Fulminating Hepatitis: Fatal. Liver cells cannot regenerate and progressive liver necrosis occurs. Hepatic encephalopathy and death occur Cirrhosis of the liver: Scarring causes injury to the liver Liver failure Liver Cancer If liver cells fail to regenerate, progresses to necrotic process, results in severe, frequently fatal form, fulminant hep. Hepatic encephalopathy, death

50 Cirrhosis of the Liver Extensive scarring of the liver caused by necrotic injury or a chronic reaction to inflammation over a prolonged period of time Risk Factors 4 Types- Laennec’s, Postnecrotic, Biliary, Cardiac Cirrhosis- chronic progressive liver condition..Destruction of hepatocyte In the end stages, it is essentially an irreversible reaction to hepatic inflammation and necrosis RF- alcohol, direst toxic effect on liver cells. Autoimmune hepatitis, Steatohepatitis, (fat/chol deposits in liver). Drugs and toxins, Biliary disease, CV disease Episodes of chronic hepatitis will do permanent injury and scarring to the liver and RF for liver Ca. Can be life-threatening but can be controlled if discovered early Laennac’s- most common type, caused by longterm alcohol use. The liver becomes enlarged, firm in early disease, smaller and nodular in end stage disease. Postnecrotic- caused by massive hepatic cell necrosis, usually from acugte viral hepatitis Biliary - caused by chronic biliary obstruction, bile stasis and infla,,ation. The liver becomes fibrotic. Cardiac- caused by severe or chronic HF. The liver becomes enlarged and congested with venous blood, resulting in cell necrosis from anoxia. Without transplant, usually fatal

51 Diagnostic Procedures
Liver biopsy EGD: Esphagastroduodenoscopy: detect esophageal varices LABS to be monitored?? WHY?? Serum liver enzymes Serum bilirubin Serum albumin CBC, WBC, Platelets: all decreased due to anemia PT/INR Ammonia levels (normal 5-110mg/dL) rise when cirrhosis prevents the conversion of ammonia to urea for excretion Creatinine levels (normal 0.6 to 1.2mg/dL may increase Liver Biospy (Most definitive) identifies the extent of cirrhosis EGD: Esphagastroduodenoscopy: detect esophageal varices Decreased absorption of fat soluble vitamins- K, No factor II, VII, IX X

52 Nursing Assessment Cirrhosis of the Liver
Monitor vital signs LOC-Neuro Pulmonary GI Integumentary GU Coagulation defects Fetor hepaticus-liver breath-end stage Inability of liver to synthesize albumin Fruity, musty odor caused by damaged liver Generalized weakness, weight loss Resp- dyspnea, hyperventilation, hypoxemai GI- loss of appetite, clay colored stools, abd pain, ascites. RUQ mass, tenderness

53 Nursing Assessment Petechiae red pinpoint and red-purple lesions,
Ecchymosis, nose bleeds, hematemesis Spider angiomas red spider -like lesions of face, upper thorax, and shoulders Dependent peripheral edema of extremities and sacrum Asterixis- tremors liver flapping tremor of the wrist and fingers Complications of portal hypertension Asterixis- Low Ca

54 Management of Cirrhosis
Non-surgical Diet- low Na, low protein, moderate fat restriction, high carb, high calories, vitamins TPN often necessary Meds-Aldactone, Lactulose, Neomycin, antacids Paracentesis Esophagogastric balloon tamponade Injection sclerotherapy STOP alcohol Surgical Peritovenous shunt or LaVeen shunt Endoscopic band ligation Non surgical- to control ascites Limit protein(500mg-2G) to keep ammonia levels low. Ammonia is a byproduct of protein metabolism Fluid restriction-1L-1500mL/day Aldactone- K sparing diuretic, reduces ascites and decreases aldosterone levels Monitor EKG, lytes, I&O, K levels, bradycardia, muscle twitching. Assess for hyponatremia: confusion, lethargy and apprehension Lactulose (Cehulac)-promotes excretion of ammonia in stool and lowers pH. Lower pH converts ammonia to ammonium ion, non absorbable that is excreted in feces. Lactulose also pulls water into the bowel lumen, increasing the number of daily stools. Maintain stool chart, F&E. Goal- 2-4 soft stools per day Neomycin- ant infective- reduces intestinal bacteria, decreases ammonia production. Nephrotoxic, ototoxic and neurotoxic Neomycin-broad spectrum AB, intestinal antiseptic, destroys normal flora, diminishes protein breakdown and decreases rate of ammonia breakdown Paracentesis- inserion of trocar catheter into abd at bedside to remove ascitic fluid from peritoneal cavity Blakemore Tube:- for bleeding esophageal varices. Balloon is inflated and stops bleeding. Pitressin a vosoconstrictor may be ordered to stop bleeding Injection sclerotherapy- via endoscope, a sclerosing agent may be injected to stop bleeding. Shunt- drains ascites through a one way valve into a tube that terminates in the SVC. Pt loses weight, decrease in abd girth, and have increased urine output. .

55 Complications of Cirrhosis
Portal Hypertension Ascites Bleeding esophageal varices Coagulation defect Jaundice Hepatic encephalopathy Hepatorenal syndrome 1, Portal HTN- Increase in pressure in portal vein. Blood flows back into spleen, causing splenomegaly, ascites, esophageal varices, prominent abd veins and hemorrhoids 2. Accumulation of free fluid containing almost pure plasma in the abd 3. Bleeding varices- blood backs up into esophageal and gastric vessels. These vessels are fragile, thin walled and will blees 4.Coag defect- due to cirrhosis, dec in synthesis of bile fats in liver, preventing absorpion of fat soluble Vit K.. Pt susceptible to bruising and bleeding 5. Jaundice- Liver cannot metabolize bilirubin 6. Hepatic encephalopathy- Altered LOC, impaired thinking and neuromuscular disturbances. A/R/O impaired ammonia metabolism. Liver can’t convert ammonia to urea.. 5 stages- from prodromal (subltle changes) to coma. 7.Hepatorenal- Primary cause of death in end stage cirrhosis. Manifested by sudden decrease in urine flow, elevated BUN and creat. Impaired urine osmolarity.. Progressive oliguria and renal failure Monitor LOC, Level of orientation, Recent memory Monitor F/E Monitor bleeding Chart 62-2Normal Ammonia mg/dL Sleepdisturbance, mood disturbances, mental status changes, speech problems- early Acute and reversbible in early stages Late- ALC, impaired thinking, neuromuscular problems

56 Bleeding esophageal varices
Hematemesis and melena Dx: endoscopy, CT, ultrasound, barium swallow, LFTs Tx: O2, IVF, Blood transfusions, I&O, Balloon tamponade, saline lavage, endoscopic tamponade, vasopressin (Pitressin) One of the major causes of death in pts with cirrhosis. Esophageal varices are dilated, toruous veins ususally found in submucosa of the lower esophagus. 2nd to portal hypertension.

57 Nursing Diagnoses Altered mental status Ineffective breathing pattern
Excess fluid volume Risk for impaired skin integrity Risk for infection Chronic pain Risk for imbalanced nutrition

58 Portal Hypertension Portal hypertension results from the abnormal blood flow pattern in liver created by cirrhosis. The increased pressure is transmitted to collateral venous channels. Sometimes these venous collaterals are dilated. Seen here is "caput medusae" which consists of dilated veins seen on the abdomen of a patient with cirrhosis of the liver. library.med.utah.edu/WebPath/LIVEHTML/LIVER061.html

59 Treatment for Cirrhosis of Liver
Injection sclerotherapy: varices are sclerosed TIPS: Transjugular intrahepatic portosystemic shunt – placement of a portal shunt for esophageal varices Surgical bypass shunting procedures: Last resort: Ascites is shunted from the abdominal cavity to the superior vena cava Liver Transplantation

60 Hepatic Encephalopathy and Coma
Early symptoms- minor mental changes and motor disturbances Progression to changes in LOC, difficult to arouse, asterixis Hyperactive reflexes then flaccid Progression to seizures and coma Encephalopathy is a complication of liver disease, occurs with liver failure and may result from the accumulation of ammonia and other toxic metabolites in blood Coma represents most severe stage of encephalopathy. Ammonia accumulates because liver cannot convert to urea Early symptoms: unkempt, altered sleep patterns, sleep during day, awake at night. Asterixis-flapping tremor of hands Tx- lactulose, decrease protein intake, enemas, IVF, vitamins, O2. Monitor ammonia levels

61 Hepatic Coma Jaundice Profound anorexia Coagulation defects
Renal failure Electrolyte disturbances Hypoglycemia Infection Encephalopathy Tx: Liver transplant, blood products, corticosteroids

62 Concept Map: Impaired Liver Function
Ineffective breathing pattern Body Image Disturbance Activity Intolerance Excess fluid volume Imbalanced Nutrition, Less than Body Requirements Risk for injury Impaired Skin Integrity Nursing Diagnoses Observe for potential bleeding complications Labs Monitor PT/INR PTTDiet: Low Na, Low fat, Low protein Small frequent meals Supplemental vitamin enriched drinks Replace vitamins: liver unable to store If serum Na is low, patient will be put on a fluid restriction Medications are administered sparingly: liver toxicity Diurectics: monitor for hypokalemia and hypotention H2 receptor antagonist: stress ulcer Lactulose- promote excretion of ammonia via stool Neomycin and metronidazole (Flagyl) removes intestinal bacteria which produces ammonia Platelets Injury- Assess LOC, cognitive level, orientation. Monitor restlessness and agitation. Obtain and record sample of handwriting.. Assess neuro signs, DTRs and ability to follow directions. Provide safe environment, prevent falls.. Stimulate and orient pt. frequently, avoid restraints. Monitor meds- esp hypnoticss, sedatives and analgesics. Monitor ammonia levels 2. Body Image- encourage pt to verbalize reactions and feeling re changes. Assess coping strategies. Encourage and assist pt in making decisions about his care. ID resources to help pt: clergy, counselor 3. GI Bleeding- Monitor VS, LOC, stool and emesis for occult or frank bleeding. Monitor Hgb and Hct. Avoid activities that increase intra-abdominal pressure. Monitor H&H ,Blood transfusions 4. Activity intolerance- assist with ADLS and hygiene. Encourage rest.Elevate HOB during meals to increase comfort. 5. Administer meds prescribed to reduce ammonia: lactulose, antibiotics 6. Skin- assess degree of discomfort related to pruritis and edema. Keep fingernails short. Provide frequent skin care. Skin care will remove waste products deposited on skin. T&P frequently.Provide oral hygien.. Comfort measures: HOB elevated 30 degrees

63 Liver Cancer HCC- hepatocellular carcinoma most common of liver cancer
Most liver tumors are unresectable 5 year survival rate is less than 9%. Clinical manifestations Rare in US, 2% of all cancers. The cancer is common in Africa. S&S- jaundice, ascites, bleeding, encephalopathy. Elevated LFTs. Because of high vascularity of the liver, common site for mets from primary Ca of esophagus, stomach, colon, rectum, breasts, lungs or malignant melnoma.

64 Risk Factors Cirrhosis Metastasis from another site Dx
AFP: Alpha-fetoprotein tumor marker Liver enzymes ALP elevated Liver biospy: definitive diagnosis

65 Treatment For Liver Cancer
Chemotherapy via an surgically implanted infusion pump Liver transplantation Portions of a liver are transplanted and will regenerate Transplantation surgery- 12 hours Immunosuppressant drugs Steroids Monitor for infection and organ rejection

66 Indications for Liver Transplant
Primary or secondary biliary cirrhosis Chronic active hepatitis with cirrhosis Liver abscesses Fatty liver infiltrates Liver Ca Indicated for diseases with irreversible damage Not commonly performed on pts with mets because Ca is likely to recur Not considered candidates: hepatorenal syndrome, AIDS, sepsis, repeated episodes of esophageal varices or active alcoholism

67 Liver Transplant Complications
1. Graft rejection Manifestations of graft rejection are: Fever Tachycardia RUQ or flank pain Dimished bile flow through t-tube or change in bile color Increased bilirubin Increased jaundice Occurs most often 1-2 wks post-op. Meds: cyclosporin A, Imuran, prednisone.
