Interventions for clients with liver, galdbladder and pancreas disorders. Clients with malnutrition and obesity..

Liver disorders Hepatitis  1.Definition: inflammation of the liver due to virus, exposure to alcohol, drugs, toxins; may be acute or chronic in nature  2.Pathophysiology: metabolic functions and bile elimination functions of the liver are disrupted by the inflammation of the liver.

Hepatitis  Widespread viral inflammation of liver cells  Hepatitis A  Hepatitis B  Hepatitis C  Hepatitis D  Hepatitis E  Hepatitis F and G are uncommon

Hepatitis Viral Hepatitis  1.Types (causative agents) a. Hepatitis A virus (HAV) Infectious hepatitis  1. Transmission: fecal-oral route, often contaminated foods, water or direct contact, blood transfusions, contaminated equipment  2. Contagious through stool up to 2 weeks before symptoms occur; abrupt onset  3. Benign, self limited; symptoms last up to 2 months

Hepatitis  Prevention of Hepatitis A  Good handwashing  Good personal hygiene  Control and screening of food handlers  Passive immunization  Incubation period :20-50 days (short incubation period)

Hepatitis  Incidence  More common in fall and winter months  Usually found in children and young adults  Infectious for 3 weeks prior and 1 week after developing jaundice  Clinical recovery 3-16 weeks

Hepatitis Hepatitis B virus (HBV)  1.Transmission:  infected blood and body fluids,  parenteral route with infusion  ingestion or inhalation of the blood of an infected person  Contaminated needles, syringes, dental instruments  Oral or sexual contact  High risk individuals include homosexual, IV drug abusers, persons with multiple sexual partners, medical workers  2.Liver cells damaged by immune response; increased risk for primary liver cancer; causes acute and chronic hepatitis, fulminant hepatitis and carrier state

Hepatitis Hepatitis C virus (HCV)  1.Transmission: infected blood and body fluids; injection drug use is primary factor  2.Initial manifestations are mild, nonspecific  3.Primary worldwide cause of chronic hepatitis, cirrhosis, liver cancer  4. Usual incubation period 7-8 weeks

Hepatitis Hepatitis E virus (HEV)  1.Transmission: fecal-oral route, contaminated water supplies in developing nations; rare in U.S.  2.Affects young adults; fulminant in pregnant women

Clinical Manifestations  Abdominal pain  Changes in skin or eye color  Arthralgia (joint pain)  Myalgia (muscle pain)  Diarrhea/constipation  Fever  Lethargy  Malaise  Nausea/vomiting  Pruritus

Complications  Acute, chronic graft rejection  Infection  Hemorrhage  Hepatic artery thrombosis  Fluid and electrolyte imbalances  Pulmonary atelectasis  Acute renal failure  Psychological maladjustment

Acute Cholecystitis  Acute cholecystitis is the inflammation of the gallbladder.  Cholelithiasis (gallstones) usually accompanies cholecystitis.  Acalculous cholecystitis inflammation can occur in the absence of gallstones.  Calculous cholecystitis is the obstruction of the cystic duct by a stone, which creates an inflammatory response.

Chronic Cholecystitis  Repeated episodes of cystic duct obstruction result in chronic inflammation  Pancreatitis, cholangitis  Jaundice  Icterus  Obstructive jaundice  Pruritus
