Study Notes

Bile

Bile is a yellow-green fluid produced by the liver and stored in the gallbladder.
It contains water, bile salts, cholesterol, phospholipids, and other substances.
Bile aids in digestion.
The liver continues to produce bile even if the gallbladder is removed.

Ascites

Ascites is the accumulation of fluid in the peritoneal cavity.
Causes include portal hypertension, vasodilation, aldosterone metabolism issues, decreased albumin synthesis, and albumin movement into the peritoneal cavity.
Assessment includes daily abdominal girth and weight measurement, noting shortness of breath, evaluating for striae, distended veins, and umbilical hernia, assessing fluid within the abdominal cavity, and monitoring fluid and electrolyte imbalances.
Treatment includes a low-sodium diet to reduce fluid retention.

Instrument Information

This document describes instruments and procedures used in the management of liver diseases.

Diuretics

Spironolactone and furosemide are diuretic medications used in the treatment of ascites.
Bed rest reduces renal filtration and sodium excretion, making loop diuretics less effective.

Paracentesis

Paracentesis involves removing fluid from the peritoneal cavity using a puncture or small surgical incision.

Transjugular Intrahepatic Portosystemic Shunt (TIPS)

TIPS treats ascites by threading a cannula into the portal vein and creating an intrahepatic shunt between portal and hepatic veins.
This reduces sodium retention and improves the renal response to diuretics.

Peritoneovenous Shunt

This redirects ascitic fluid to the systemic circulation via abdominal and thoracic catheters draining into the superior vena cava through a one-way valve.
It is rarely used.

Nursing Management

In-hospital monitoring includes fluid status (intake/output, abdominal girth, daily weight), respiratory status, and serum ammonia, creatinine, and electrolytes to assess electrolyte balance, response to therapy, and hepatic encephalopathy.

Esophageal Varices

Esophageal varices occur in 30% of patients with compensated cirrhosis and 60% of patients with decompensated cirrhosis.
The first bleeding episode has a 10%-30% mortality rate.
These are dilated, tortuous veins in the lower esophagus, extending to the stomach.
They are usually caused by portal hypertension.
Manifestations include hematemesis, melena, general deterioration, and shock.
Patients with cirrhosis should undergo endoscopy screening every 2 to 3 years.

Treatment of Bleeding Varices

Treatment for bleeding varices includes managing shock by administering oxygen, IV fluids, electrolytes, volume expanders, blood and blood products, vasopressin, somatostatin, octreotide.
Additional treatment includes nitroglycerin in combination with vasopressin, propranolol and nadolol, balloon tamponade, endoscopic sclerotherapy, endoscopic variceal ligation, Trans jugular intrahepatic portosystemic shunt, surgical management, surgical bypass procedures, and devascularization and transection.

Nursing Management of Esophageal Varices

Nursing management of esophageal varices focuses on maintaining a safe environment, preventing injury, bleeding, and infection, administering prescribed treatments, monitoring for potential complications, encouraging deep breathing and position changes, and providing education and support to the patient and family.

Pancreatitis

Pancreatitis is an inflammation of the pancreas, occurring in acute and chronic forms.

Acute Pancreatitis

Acute pancreatitis is a medical emergency with a high risk of life-threatening complications and mortality.
It does not usually lead to chronic pancreatitis.
Clinical manifestations include abdominal pain, tenderness, back pain, frequent pain of sudden onset, respiratory distress, and hypotension.
Treatment focuses on relieving symptoms, providing respiratory care, and biliary drainage.

Chronic Pancreatitis

Chronic pancreatitis is characterized by progressive destruction of the pancreas.
Classic clinical and diagnostic findings may not be present in the early stages.
Recurring attacks of severe upper abdominal and back pain, often accompanied by vomiting, are common.
Opioids may not fully relieve pain.
As the disease progresses, attacks become more frequent, painful, and last longer.
Pain can sometimes be painless.
Weight loss, frequent, frothy, and foul-smelling stools occur due to impaired fat digestion (steatorrhea).

Potential Complications and Management of Chronic Pancreatitis

Recurring attacks are managed by controlling pain and discomfort.
Endocrine and exocrine deficiencies need to be addressed.
Nutritional status needs to be monitored and improved.
Potential complications include fluid and electrolyte problems, necrotizing pancreatitis, shock, and multiple organ dysfunction syndrome.
Surgical intervention and post-acute management may be necessary.
Nursing management involves alleviating pain, improving breathing, and maintaining skin integrity.

Other Factors

Alcohol consumption, malnutrition, and smoking are factors contributing to both acute and chronic pancreatitis.

Nursing Interventions for the Patient with Cirrhosis of the Liver

Portal Hypertension: Obstructed blood flow through the liver leads to increased pressure throughout the portal venous system, resulting in ascites and esophageal varices.
Fatty Liver (Alcoholic Liver, Hep A): Healthy liver cells are replaced by scar tissue.
Manifestations and Complications: Liver enlargement, portal obstruction, ascites, infection (peritonitis), varices, vitamin deficiencies, anemia and mental deterioration.
Nursing Interventions: Rest, positioning for optimal respiratory efficiency, oxygen administration, mild exercise with rest periods, nutritional support with high-calorie diet, sodium restriction, protein modifications or restrictions, dietary supplements of vitamins, minerals and B-complex, skin care, consideration of patient preferences, and prevention of scarring through consistent position changes, gentle skin care, and reduction of scratching.
General Notes:
- Nonopioid methods are preferred for pain relief because opioids can exacerbate pain.
- Surgical management is not the primary treatment approach for liver cirrhosis.
