The Bilary Tree
|
Left Hepatic Duct. Common Bile Duct. Cystic Duct. Pancreatic Duct. |
|
Compensated Cirrhosis. Liver is scarred but can still perform essential functions
|
Decompensated Cirrhosis. Liver is impaired with obvious signs of liver malfunction |
|
Types of Hepatitis
|
H.A.V.: Oral, fecal, contaminated H2O, shellfish, contaminated food handlers. H.B.V.: Blood, needles, close person to person contact. H.C.V.: Blood illicit I V drugs, needles. H.D.V.: Blood, needs H.B.V. to survive. H.E.V.: Oral, Fecal, usually contaminated H2O |
|
Portal Hypertension
|
obstruction of the flow of blood through the liver. It is responsible for ascites, splenomegaly, and the formation of varices. 1500mls per minute. Blood backs up. Collateral circulation, very fragile thin veins, bleeding ulcers |
|
Ascites
|
cavity. Decreased plasma proteins, albumin, & increased pressure from portal hypertension results in a fluid shift from the vascular system. Interventions; Paracentesis, Diuretics, Sodium Restrictions. |
|
Protein shift from blood vessels into lymph space. Lymph system can't handle fluid & dumps it into the peritoneal. Hyperaldosteronism |
Esophageal Varices; Very fragile bleed easily, aggravated by alcohol, coarse food popcorn, nuts, straining, coughing, sneezing. Beta blockers (carvedilol, atenolol, metoprolol, labetalol) lopressors |
|
Interventions for Portal Hypertension
|
Injection Scleropathy. Endoscopic variceal ligation (EVL banding). Transjugular Intrahepatic Portal Systemic Shunt (TIPS) |
|
Portal Systemic Encephalopathy; (Cerebral Edema) |
Reversible with early interventions. 4 stages. 1st. personality changes, sleep disturbances. 2nd. mental confusion, asterixis (muscle tremors). 3rd. marked mental confusion, stuporous. 4th. seizures, unresponsive, positive Babinski's sign. 4th stage terminal. |
|
Increased ammonia levels (Lactulos). High protein diet (too much). Infection. Hypovolemia. Hypokalemia. |
G.I. Bleeding. Drugs (opioids, sedatives, analgesics, illicit drugs, diuretics, hypnotics). Toxic waste in blood. |
|
HEPATORENAL SYNDROME
|
Manifestations: Sudden decrease in urine output < 500ml in 24 hours. Elevated BUN. Increased Urine Osmolarity |
|
Drug Therapy for Complications |
Aldactone lessens Ascities. S.E. increases K. Vassopressin. octreotide acetate (Sandostatin) (Esophagel varices). Vitamin K, Diuretics, H2 Receptor Blockers(Tagament, Protonix) |
|
CARE I / O; Daily weights. Abdominal girth measurement. Avoid NSAIDS. Leads to bleeding. Control coughing. Provide rest periods. Low NA diet. Maintain rest & comfort. Maintain fluid & electrolyte balance. |
Management Care. Blood transfusion. Paracentesis. Esophagogastric balloon tamponade. Vasoconstrictive therapy. Surgical Mgt. Transjugular intrahepatic portal systemic shunt Educate patient on medication, mobility, the treatment plan. |
|
Treatment Goals. 1. Maintain liver function at its current level & prevent further deterioration of the organ. 2. Maintain electrolytes within normal limits. 3. Maintain sufficient respiratory function. 4. prevent or resolve G.I. bleeding |
5. provide adequate nutritional intake & a positive nitrogen balance. |
|
Fulminant Hepatic Failure. Syndrome of sudden & severely impaired liver function. Prognosis is worse than chronic liver failure. Causes: viral hepatitis, toxic meds, chemicals, metabolic disorders, structural changes. |
Liver Transplantation: Used in treatment of ESLD, primary malignant neoplasm of the liver.
Donor livers obtained primarily from trauma victims who have not had liver damage. Donor liver cooled in saline solution that preserves the organ for up to 8 hours |
|
Transplant Complications: Acute, chronic graft rejection. Infection. Hemorrhage. Hepatic artery thrombosis. Fluid & Electrolyte imbalances. Pulmonary atelectasis. Psychological maladjustment. |
Excess Fluid Volume: Interventions Nutritional therapy, restrict fluids, sodium. Drug Therapy, diuretics. Paracentesis: removal of fluid |
