      3. Personality change
    2. Jaundice
    3. Coagulopathy
      1. Bleeding (e.g. Gastrointestinal Bleeding)
    4. Acute Renal Failure (Hepatorenal Syndrome)
    5. Hypoglycemia
    6. Acute Pancreatitis
    7. Cardiopulmonary failure
    8. Ascites (due to Portal Hypertension)
  8. Prognosis: Factors associated with poor outcomes
    1. Advanced age
    2. Halothane exposure
    3. Hepatitis C
    4. Coma (80% Mortality)
    5. Rapid decrease in liver span
    6. Respiratory failure
    7. Marked ProTime prolongation
    8. Factor V Level <20%
  9. Management
    1. Targeted therapy
      1. Delivery for pregnancy related Acute Liver Disease (especially Acute Fatty Liver of Pregnancy)
      2. Withdraw all known Hepatotoxins
      3. Treat known Hepatotoxin exposures
        1. Consult with poison control and hepatology
        2. Example: N-Acetylcysteine for Acetaminophen Overdose or Amanita muscaria ingestion
    2. Supportive care
      1. ABC Management
        1. Endotracheal Intubation often required
      2. Fluid and electrolytes
        1. Volume expansion with crystalloid initially, but avoid Fluid Overload
        2. Correct acid-base status and electrolyte abnormalities
        3. Monitor Serum Glucose
          1. Correct Hypoglycemia with IV D10 or D20 prn
      3. Prevent GI Bleed
        1. H2 Blockers to maintain gastric pH >3.5
      4. Monitor for infection
        1. Complicated by Bacterial or fungal infection in 80% of cases
        2. Infection is often occult with non-specific changes in status (e.g. worsening encephalopathy)
        3. Routinely monitor urine, Chest XRay and other markers of infection
        4. Consider prophylactic antibiotics
      5. Other measures
        1. Control systemic Hypertension
        2. Consider evaluation of Intracranial Pressure (questionable efficacy)
          1. Lower Intracranial Pressure with Mannitol IV prn
    3. Liver Transplant Indications
      1. Grade 3-4 Encephalopathy
      2. Adverse prognostic indicators as above

Liver Failure, Acute (C0162557)

Definition (MSHCZE) Rychlý nástup akutního SELHÁNÍ JATER, známého také jako fulminantní jaterní selhání, je forma onemocnění způsobená těžkým poškozením jater nebo masivní ztrátou HEPATOCYTŮ. Je to charakteristické při náhlém rozvoji jaterní dysfunkce a při ŽLOUTENCE. Akutní selhání jater se může vyvinout až v cerebrální dysfunkci či dokonce v jaterní kóma, což závisí na etiologii, která může zahrnovat jaterní ischémii, otravu léky, maligní infiltraci a virové hepatitidy jako např. potransfúzní hepatitidu typu B a C (HEPATITIDA B, HEPATITIDA C). R
Definition (NCI) Rapid deterioration of liver function causing encephalopathy and coagulopathy. It results from damage to the liver parenchyma usually secondary to acetaminophen overdose or viral infections.
Definition (MSH) A form of rapid-onset LIVER FAILURE, also known as fulminant hepatic failure, caused by severe liver injury or massive loss of HEPATOCYTES. It is characterized by sudden development of liver dysfunction and JAUNDICE. Acute liver failure may progress to exhibit cerebral dysfunction even HEPATIC COMA depending on the etiology that includes hepatic ISCHEMIA, drug toxicity, malignant infiltration, and viral hepatitis such as post-transfusion HEPATITIS B and HEPATITIS C.
