Retention of fluid and sodium results in increased pressure in blood vessels and lymphatic channels, resulting in portal hypertension; Ascites is thus a result of
Portal Hypertension, hypoalbuminemia, and hyperaldosteronism *Hepatic insufficiency gradually causes distention of veins in the upper part of the body including esophageal vein
In the later stages of the cirrhosis disease, it is characterized by
Dyspepsia, changes in bowel habits, gradual weight loss, ascites, enlarged spleen, malaise, nausea, jaundice, ecchymoses and spider telangiectases which are small dilated bood vessels with a bright red center point and spider like branches
Where does spider telangiectases appear on the body?
Nose, cheeks, upper trunk, neck, and shoulders *These later manifestations are the result of scarring liver tissue that produces chronic failure of liver function and fibrotic changes that cause obstruction of the portal circulation
What is the cause of the GI organs and the spleen becoming congested and not functioning properly?
When enough cells of the liver become involved to interfere with its function and obstruct its circulation
Why does Anemia occur in Cirrhosis?
Because of the body's decreased ability to produce red blood cells RBC's *Cirrhotic liver cannot absorb vitamin K or produce the clotting factors VII, IX, X
May occur with heavy alcohol consumption. Amount of alcohol that causes damage to the liver differs
Alcohol related liver disease *Chances for developing cirrhosis alcohol related increase for women when they ingest more than two or three drinks per day and for men when they drink three or four drinks per day
Results from fat building up in the liver. Incidence of this condition, is increasing as a result of the growing obesity population
NAFLD "Nonalcoholic fatty liver disease" *Also associated with diabetes, coronary artery disease and use of corticosteroids
Because Cirrhosis is not always known, alcoholism is by far the greatest factor leading to Cirrhosis. It is believed to result from the combination of
Alcohol's hepatotoxic effect on liver coupled with the common problem of protein malnutrition seen in alcoholics
What do you assess before the procedure of Endoscopic for pancreatitis?
Prothrombin time and INR, tell pot that test takes a[[rpox 1-2 hrs during which time they must lie completely motionless on hard xray table which may be uncomfortable *Withhold food and fluids for 8 hrs before examination obtain pt's signature for consent * After, keep pt on NPO until gag reflex returns assess for abdominal pain tenderness and guarding which are signs of perforation
Assess for S&S of pancreatitis which is the most common ERCP
Complication, including nausea, abdominal pain, fever, chills, vomiting and diminished or absent bowel sounds *Signs of hypovolemic shock, including decreased BP, increased pulse and respirations, SOB, cool clammy skin and decreased urine output
What are organs that assist with digestion?
Liver, gallbladder, and exocrine pancreas
Cirrhosis is ranked as the twelfth leading cause of
Death in the US *Approx 38,000 ppl die each yr from disease. Slightly more men are diagnosed with cirrhosis than women. More than 100,000 people have the disease
When can the liver not be able to regenerate its self?
When Cirrhosis is present *Overgrowth of new and fibrous tissue restricts flow of blood to the organ contributing to its destruction
ERCP
Endoscopic Retrograde Cholangiopancreatography enables visualization not only of biliary system but also of the pancreatic duct. *Test involves inserting a fiberoptic duodenoscope through oral pharynx through esophagus and then stomach into the duodenum
The ERCP of pancreas is a sensitive and reliable procedure for detecting what?
Significant degrees of pancreatic dysfunction *Can also be used to evaluate obstructive jaundice, remove common bile duct stones and place biliary and pancreatic duct stents to bypass obstruction
What indicates the presence of a tumor?
Localized pancreatic duct narrowing
Various of types of Hepatitis virus can be detected by what?
Antigen, antibody levels, and incubation periods
Notify lab of any antibiotics pt is currently taking because certain broad spectrum antibiotics such as
Neomycin can cause a decreased ammonia level giving inaccurate test results
What is the normal serum amylase test value?
60-120 somogyi units/dL or 30 to220 units/L SI units
How can the biliary tract be evaluated safely accurately and noninvasively?
By intravenous IV injection of technetium and positioning patient under camera to record distribution of tracer in the liver biliary tree, gallbladder and proximal small bowel
The primary use of the gallbladder scanning study is to diagnose
Acute Cholecystitis [inflammation of gallbladder] *This procedure is superior o=to oral cholecystography, ultrasonography and computed tomography CT of abdomen for detection of acute Cholecystitis
What nursing interventions can you do for gallbladder scanning with patient?
Reassure pt that exposure to radioactivity is minimal because on a trace dose of the radioisotope is used. Pt is on NPO status from midnight until examination is complete
A safe, simple and valuable method of diagnosing pathologic liver conditions; specially designed needle is inserted through skin making it a percutaneous procedure, between the sixth and seventh or eighth and ninth intercostal space and into the liver
Needle liver Biopsy *Pt lies supine with right arm over the head, instructed to exhale fully and not breathe while needle is inserted *Often done using ultrasound or CT guidance
What is the percutaneous liver biopsy used to diagnose?
Various liver disorders such as cirrhosis, hepatitis and drug related reactions, granuloma or tumor
A procedure used to outline and detect structural changes of liver
A radioisotope liver scan *Given intravenously *Later a gamma ray detecting device "Geiger counter" is passed over the pt's abdomen. This record distribution of radioactive particles in the liver
When can the spleen be visualized by the detector?
When technetium-99m sulfur is used
Ammonia is a by product of
Protein metabolism, most ammonia is made by bacteria acting on proteins in the intestine
What to make sure has to be ordered for liver biopsy?
Measurements of platelets, clotting or bleeding time, prothrombin time, and INR report any abnormal values
0.1 to 0.4 mg/dL
Direct bilirubin
0.2 to 0.8 mg/dL
Indirect bilirubin
0.3 to 1.2 mg/dL
Total bilirubin
