Liver Cirrhosis and Portal Hypertension: Nursing Study Guide

Liver cirrhosis is a chronic, progressive disease in which healthy liver tissue is replaced by scar tissue, leading to irreversible damage and multisystem complications. This guide reviews the pathophysiology, clinical signs, complications such as portal hypertension and hepatic encephalopathy, and the nursing priorities essential for safe care and exam success.

What Is Cirrhosis?

Cirrhosis is a chronic, progressive liver disease in which healthy hepatic tissue is replaced by scar tissue, leading to irreversible liver damage and potential liver failure.

Causes of Cirrhosis

• Alcohol-related liver disease — most common cause in Western countries
• Chronic viral hepatitis — hepatitis B and C
• Nonalcoholic fatty liver disease (NAFLD) — associated with obesity, diabetes, and metabolic syndrome
• Autoimmune hepatitis — immune system attacks liver cells
• Hemochromatosis — iron overload

Pathophysiology

Chronic liver injury triggers fibrosis. Scar tissue replaces normal liver architecture, disrupting blood flow through the liver and producing portal hypertension, which drives most of the systemic complications seen in cirrhosis.

Clinical Presentation (ABCDEFGHIJ Mnemonic)

• A — Ascites: fluid accumulation in the peritoneal cavity
• B — Bruising: easy bleeding from decreased clotting factors
• C — Clubbing: enlargement of fingertips from chronic hypoxemia
• D — Dupuytren's contracture: thickening of palmar fascia causing finger flexion
• E — Encephalopathy: confusion, asterixis, coma from ammonia accumulation
• F — Fetor hepaticus: musty, sweet breath odor from mercaptans
• G — Gynecomastia: breast enlargement in men from hormone imbalance
• H — Hepatomegaly: enlarged liver early; small, shrunken liver late
• I — Icterus: jaundice (yellowing of skin and eyes)
• J — Jaundice: same as icterus; included as a memory aid

Major complications include portal hypertension, ascites, esophageal varices, hepatic encephalopathy, coagulopathy, and hepatorenal syndrome.

Portal Hypertension

Portal hypertension is increased blood pressure in the portal venous system (normal 1–5 mmHg; >10 mmHg is hypertension). It leads to esophageal varices, ascites, splenomegaly, and hepatic encephalopathy.

Esophageal Varices

• Esophageal varices are dilated veins in the lower esophagus formed when collateral circulation shunts blood away from the cirrhotic liver.
• Variceal bleeding is a life-threatening emergency presenting with hematemesis (bright red or coffee-ground) or melena.

Acute management

• Assess ABCs; establish two large-bore IV lines
• Administer IV fluids and blood transfusions
• Give octreotide to reduce portal pressure
• Give ceftriaxone to prevent infection
• Endoscopic variceal ligation (banding) is the preferred treatment for active bleeding

Prevention

• Beta-blockers (propranolol, nadolol) prevent first or recurrent bleeding

Ascites

Ascites is fluid accumulation in the peritoneal cavity from portal hypertension and hypoalbuminemia. It presents with abdominal distension, weight gain, and shortness of breath.

• Paracentesis is used for diagnosis and therapeutic relief
• A SAAG ≥1.1 g/dL indicates portal hypertension as the cause
• Sodium restriction (<2 g/day)
• Spironolactone is first-line; furosemide is added if needed
• IV albumin is given after large-volume paracentesis (>5 liters) to prevent circulatory dysfunction

Spontaneous Bacterial Peritonitis (SBP)

• Infection of ascitic fluid
• Presents with fever, abdominal pain, and worsening encephalopathy
• Diagnosis: ascitic fluid PMN >250 cells/mm³
• Treatment: IV cefotaxime or ceftriaxone

Hepatorenal Syndrome (HRS)

HRS is progressive kidney failure in advanced liver disease, caused by splanchnic vasodilation leading to renal vasoconstriction.

• Type 1 HRS: rapid; serum creatinine doubles to >2.5 mg/dL in <2 weeks
• Type 2 HRS: slower; associated with refractory ascites
• Diagnosis is one of exclusion (no shock, no nephrotoxins, no proteinuria)
• Treatment: vasoconstrictors (terlipressin or norepinephrine) plus IV albumin
• Liver transplantation is the only definitive treatment

Coagulopathy

• The liver produces clotting factors II, VII, IX, and X
• Decreased production causes prolonged PT/INR, easy bruising, and bleeding risk
• Vitamin K can help but does not correct underlying liver dysfunction
• Fresh frozen plasma (FFP) is given for active bleeding or before invasive procedures

Hepatic Encephalopathy

Hepatic encephalopathy is neuropsychiatric dysfunction caused by accumulation of ammonia and other toxins.

• Lactulose acidifies the colon and traps ammonia; goal is 2–3 soft stools per day
• Rifaximin for recurrent episodes
• Avoid sedatives and opioids, which worsen encephalopathy

Stages of Hepatic Encephalopathy

• Stage 0: Normal mental status; no abnormalities
• Stage 1: Mild confusion, euphoria or anxiety, shortened attention span; mild asterixis, sleep disturbance (day-night reversal)
• Stage 2: Lethargy, disorientation to time, inappropriate behavior; asterixis (liver flap), slurred speech, ataxia
• Stage 3: Somnolence, stupor, disorientation to place, marked confusion; hyperreflexia, rigidity, asterixis still present — patient is arousable but disoriented
• Stage 4: Coma, unresponsive to painful stimuli; decerebrate or decorticate posturing; no asterixis — patient is unarousable

Asterixis is a flapping tremor of the hands seen when the wrists are extended.

Diagnostic Tests

• Liver function tests: elevated AST, ALT, alkaline phosphatase; low albumin
• PT/INR: prolonged (clotting factor deficiency)
• CBC: thrombocytopenia (from splenomegaly)
• AST/ALT ratio: AST > ALT in alcoholic cirrhosis
• Liver biopsy: gold standard for diagnosis
• Ultrasound: nodular liver, splenomegaly, ascites

Nursing Priorities

• Monitor daily weight and abdominal girth
• Enforce sodium restriction (<2 g/day)
• Administer diuretics (spironolactone first)
• Assist with paracentesis
• Give lactulose to maintain 2–3 soft stools per day
• Implement fall precautions for confused patients
• Monitor for aspiration and for bleeding (hematemesis, melena, easy bruising)
• Assess for jaundice, ascites, peripheral edema, mental status changes, asterixis, signs of SBP (fever, abdominal pain), and signs of HRS (rising creatinine, decreasing urine output)

Patient Teaching

• Avoid alcohol completely
• Follow a low-sodium diet (<2 g/day)
• Take diuretics and lactulose as prescribed
• Report black stools, blood in vomit, easy bruising, confusion, sleep changes, or hand flap
• Get vaccinated against hepatitis A and B, influenza, and pneumococcus

Common Exam Traps

• Asterixis (liver flap) signals hepatic encephalopathy
• Spironolactone is first-line for ascites; furosemide is added if needed
• Lactulose causes diarrhea — goal is 2–3 soft stools per day
• IV albumin is given after large-volume paracentesis (>5 L)
• Octreotide treats acute variceal bleeding; beta-blockers prevent rebleeding
• SBP requires ascitic fluid PMN >250 cells/mm³
• HRS presents with rising creatinine and low urine output; treat with vasoconstrictors + albumin
• Liver transplantation is the only cure for end-stage cirrhosis and HRS
• The ABCDEFGHIJ mnemonic recalls signs of chronic liver disease
• Hepatic encephalopathy progresses from confusion (Stage 1) to coma (Stage 4)

Key takeaways

• Cirrhosis is irreversible scarring of the liver that drives portal hypertension and multisystem complications.
• Variceal bleeding is an emergency: ABCs, two large-bore IVs, fluids/blood, octreotide, ceftriaxone, and endoscopic banding.
• Ascites management: sodium restriction, spironolactone (± furosemide), paracentesis, and IV albumin after large-volume taps.
• Lactulose (titrate to 2–3 soft stools/day) and rifaximin are mainstays for hepatic encephalopathy; avoid sedatives.
• SBP = ascitic PMN >250 cells/mm³ → IV cefotaxime/ceftriaxone; HRS → vasoconstrictors + albumin.
• Liver transplantation is the only definitive treatment for end-stage cirrhosis and HRS.
