Study Notes
Acute Liver Failure (ALF)
- Characteristic feature: No specific definition, but a combination of clinical and biochemical features
Management of ALF Patients
- Patients with grade 3 encephalopathy: Intensive care unit (ICU) admission recommended
- Treatment of encephalopathy: No recommendation for lactulose or rifaximin use
- Patients with grade 2 or higher hepatic encephalopathy: Hyperammonemia management involves reduction of ammonia production and enhancement of ammonia removal
Coagulopathy Management
- INR correction: Not recommended in the absence of active bleeding or impending high-risk procedure
- More accurate assessment of coagulopathy: Viscoelastic tests (e.g., thromboelastography) compared to INR
Treatment of ALF Patients
- Patients with grade 2 or higher encephalopathy: Consideration for ICU admission and urgent evaluation for liver transplantation
- First-line vasopressor for hypotension refractory to fluid resuscitation: Norepinephrine
- Secondary agent for hypotension not responsive to norepinephrine: Vasopressin
- Patients with ALF due to mushroom poisoning: Silibinin treatment initiation
- Patients with non-APAP ALF: Initial treatment with N-acetylcysteine (NAC) not recommended
- Patients with ALF and Hepatic Encephalopathy Grade 1: Close monitoring and supportive care
Infection Management
- Early assessment for infection: Prudent due to high risk of bacterial infections
- Prophylactic antibiotics: Not recommended for routine use in patients with ALF
