Acute and chronic liver failure, hepatic encephalopathy staging, lactulose protocol, portal hypertension complications, coagulopathy, hepatorenal syndrome, and comprehensive nursing management.
1. Acute vs. Chronic Liver Failure
| Feature | Acute (Fulminant) Liver Failure | Chronic Liver Failure (Cirrhosis) |
|---|
| Onset | <26 weeks in patient without prior liver disease | Years of progressive injury and fibrosis |
| Common causes | Acetaminophen OD (#1 in US), viral hepatitis (A, B, E), ischemic hepatitis, drug/toxin | Alcohol (#1 in US), NASH/NAFLD (#2), hepatitis B/C, autoimmune, Wilson's disease, hemochromatosis |
| Main risks | Cerebral edema (ICP), coagulopathy, multi-organ failure, hypoglycemia | Portal hypertension, varices, ascites, SBP, HE, HRS, HCC |
| Prognosis | Spontaneous recovery possible if cause removed; transplant for severe cases | Progressive; transplant for MELD ≥15–18 |
2. Child-Pugh and MELD Scores
Child-Pugh Score (5 parameters, 1–3 points each; max 15):
1. Bilirubin (<2 / 2–3 / >3 mg/dL)
2. Albumin (>3.5 / 2.8–3.5 / <2.8 g/dL)
3. INR (<1.7 / 1.7–2.3 / >2.3)
4. Ascites (none/mild/moderate-severe)
5. Encephalopathy (none/grade 1–2/grade 3–4)
Class A (5–6): well-compensated; Class B (7–9): significant impairment; Class C (10–15): decompensated, high mortality
MELD Score = used for organ allocation priority; higher = sicker; MELD ≥15 typically listed for transplant; MELD ≥40 = 71% 3-month mortality without transplant
3. Hepatic Encephalopathy (HE)
Neuropsychiatric dysfunction from liver's failure to clear nitrogenous waste (primarily ammonia) from portal circulation. Ammonia crosses blood-brain barrier → cerebral dysfunction.
| Grade | Consciousness | Intellectual Function | Neurological Findings |
|---|
| Grade 0 (minimal/covert) | Normal | Subtle impairment on psychometric testing only | Normal exam; asterixis absent |
| Grade 1 (mild) | Mild confusion; shortened attention span | Impaired addition/subtraction; personality changes; sleep disturbances | Asterixis (flapping tremor) may be present |
| Grade 2 (moderate) | Lethargic, drowsy | Disoriented to time; inappropriate behavior | Asterixis present; slurred speech |
| Grade 3 (severe) | Somnolent but arousable | Disoriented to place and time; markedly confused | Asterixis; hyperreflexia; rigidity |
| Grade 4 (coma) | Unresponsive/coma | None | No asterixis; decerebrate/decorticate posturing; pupillary changes |
Asterixis (Liver Flap)
Ask patient to extend arms and dorsiflex wrists (hold arms out with wrists cocked back). Observe for flapping tremor (involuntary rapid flexion/extension of wrist) — like a bird flapping wings. Present in grades 1–3 HE. Also seen in uremia, hypercapnia (CO2 narcosis), and severe electrolyte disorders.
HE Triggers (Precipitate or Worsen HE)
- GI bleeding (protein load from blood in gut → ammonia production)
- Infection (especially SBP)
- Constipation (increased ammonia production)
- Dehydration and electrolyte disturbances (especially hypokalemia, hyponatremia)
- Medications: benzodiazepines, opioids, sedatives (profoundly worsen HE)
- Dietary protein excess (less critical than previously thought — low protein diet NOT recommended; adequate protein is needed)
- Renal failure (decreased ammonia clearance)
- Diuretic overuse (dehydration, hyponatremia, hypokalemia)
- TIPS (transjugular intrahepatic portosystemic shunt) — bypasses liver → more ammonia in systemic circulation
Lactulose Protocol
Mechanism: Lactulose (non-absorbable disaccharide) → acidifies colon → traps ammonia as NH4+ (can't be absorbed) → ammonia excreted in stool. Also acts as cathartic (2–3 soft BMs/day = goal).
Dosing:
Oral/NG: 30–45 mL q1–2h until BM, then titrate to 2–3 soft BMs/day
Lactulose retention enema (for grade 3–4 HE, unable to take orally): 300 mL lactulose + 700 mL water, retain 30–60 min
Monitoring: Stool frequency and consistency (goal: 2–3 soft BMs/day); avoid excessive diarrhea → hypernatremia + dehydration which worsens HE; serum ammonia level (does not always correlate with clinical grade — treat clinically)
Rifaximin (non-absorbable antibiotic): add-on therapy for recurrent HE; reduces gut ammonia-producing bacteria
4. Portal Hypertension Complications
Esophageal and Gastric Varices
- Dilated portosystemic vessels from portal hypertension (>10–12 mmHg); bleed at >12 mmHg
- Variceal bleed: massive hematemesis; mortality 15–20% per episode
- Treatment: octreotide (vasoconstrictive; reduces portal pressure) + ceftriaxone (prophylactic antibiotics reduce SBP risk and improve survival) + emergent EGD (band ligation preferred; sclerotherapy second line)
- Refractory variceal bleeding: Sengstaken-Blakemore tube (inflate GASTRIC balloon first, then esophageal if needed; ALWAYS keep scissors at bedside to cut tube if airway compromise); TIPS procedure
- Primary prophylaxis: non-selective beta-blocker (propranolol or nadolol) reduces portal pressure; reduces variceal bleed risk
Ascites
- Fluid accumulation in peritoneal cavity from portal hypertension + hypoalbuminemia
- Diagnosis: SAAG (serum-ascites albumin gradient). SAAG ≥1.1 g/dL = portal hypertension. SAAG <1.1 = non-portal cause (malignancy, TB, pancreatitis)
- Treatment: sodium restriction (2 g/day), spironolactone (aldosterone antagonist, 1st-line diuretic for cirrhotic ascites) ± furosemide; large-volume paracentesis (LVP) for refractory ascites → give IV albumin 6–8 g per liter removed to prevent paracentesis-induced circulatory dysfunction
- Post-paracentesis: coagulopathy (hold if INR >2.0 or PLT <20k for therapeutic — controversial); monitor closely for 2 hr afterward
Spontaneous Bacterial Peritonitis (SBP)
SBP diagnostic criteria: Ascitic fluid PMN (neutrophil) count >250 cells/mm³ (without obvious secondary cause)
Organisms: E. coli, Klebsiella, Streptococcus (gram negatives usually)
Treatment: Cefotaxime or ceftriaxone IV × 5 days; add IV albumin (1.5 g/kg on diagnosis, 1 g/kg on day 3) → reduces hepatorenal syndrome risk
Prophylaxis for recurrence: Norfloxacin or trimethoprim-sulfamethoxazole daily
Primary prophylaxis indications: Ascitic protein <1.5 g/dL + renal dysfunction OR MELD >15 OR Child-Pugh C; upper GI bleed (all cirrhotics with variceal bleed)
5. Coagulopathy of Liver Disease
The liver synthesizes
all coagulation factors except VIII (made by vascular endothelium). In liver failure: PT/INR prolonged, fibrinogen low, thrombocytopenia (from splenomegaly sequestering platelets).
Management:
- Vitamin K: give if deficient (parenteral if not absorbing PO); may not fully correct INR in synthetic failure
- Active bleeding: FFP (replaces all factors), cryoprecipitate (fibrinogen + VIII + vWF), platelets if <50k
- Avoid routine INR correction without active bleeding (liver disease patients have "rebalanced" hemostasis — INR overestimates bleeding risk; they are equally at risk for clotting)
- Kcentra (4-factor PCC) for urgent reversal
6. Hepatorenal Syndrome (HRS)
Definition: Functional AKI in cirrhotic patients without intrinsic kidney disease — caused by extreme renal vasoconstriction from portal hypertension
Types: HRS-AKI (formerly Type 1): rapid deterioration (Cr doubles to >2.5 in <2 weeks); HRS-CKD (formerly Type 2): slower progression
Treatment:
- First: rule out other causes (hypovolemia — give albumin challenge; nephrotoxins — stop NSAIDs, aminoglycosides, contrast)
- IV albumin 1 g/kg/day + vasoconstrictors: norepinephrine (ICU) or terlipressin (not available in US) or midodrine + octreotide (outpatient)
- Liver transplant is the only definitive treatment
- AVOID NSAIDs and nephrotoxins in ALL cirrhotic patients
NCLEX High-Yield: Liver Failure
- Asterixis (liver flap) = hallmark of hepatic encephalopathy; grades 1–3
- Lactulose goal: 2–3 soft BMs/day; traps ammonia in stool
- HE triggers: GI bleed, infection, constipation, sedatives, dehydration, diuretics
- Avoid benzodiazepines and opioids in hepatic encephalopathy (worsen HE)
- SAAG ≥1.1 g/dL = portal hypertension
- SBP: ascitic PMN >250/mm³; treat cefotaxime + IV albumin
- Variceal bleed: octreotide + ceftriaxone + emergent EGD
- Sengstaken-Blakemore tube: GASTRIC balloon first; scissors at bedside (airway emergency)
- LVP: give IV albumin 6–8 g per liter removed
- Liver synthesizes all clotting factors except factor VIII
- HRS: functional AKI; only definitive treatment = liver transplant
