Transcript 10.Interventions for clients with liver, gallbladder and

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






Diet therapy
Drug therapy includes:
 Antiemetics

Fatty Liver
(Steatohepatitis)
 Fatty liver is caused by the
accumulation of fats in and around the
hepatic cells.
 Causes include:
 Diabetes mellitus
 Obesity
 Elevated lipid profile
 Many clients are asymptomatic
Hepatic Abscess
 Liver invaded by bacteria or protozoa
causing abscess
 Pyrogenic liver abscess; amebic
hepatic abscess
 Treatment usually involves:
 Drainage with ultrasound guidance
 Antibiotic therapy
Liver Trauma
 The liver is the most common organ injured
in clients with penetrating trauma of the
abdomen, such as gunshot wounds and
stab wounds.
 Clinical manifestations include abdominal
tenderness, distention, guarding, rigidity.
 Treatment involves surgery, multiple blood
products.
Cirrhosis
 Cirrhosis is extensive scarring of the liver,
usually caused by a chronic irreversible
reaction to hepatic inflammation and
necrosis.
 Complications depend on the amount of
damage sustained by the liver.
 In compensated cirrhosis, liver has
significant scarring but performs essential
functions without causing significant
symptoms.
