Acute and subacute hepatic failure, classified under ICD-10 code K72.0, represents a critical medical condition characterized by a rapid decline in liver function. This condition can arise from various causes, including viral hepatitis, drug-induced liver injury, and metabolic disorders. The management of acute hepatic failure is complex and requires a multidisciplinary approach. Below, we explore the standard treatment approaches for this condition.

Initial Assessment and Stabilization

Clinical Evaluation

The first step in managing acute hepatic failure involves a thorough clinical evaluation. This includes:
- History Taking: Identifying potential causes such as recent infections, medication use, or exposure to toxins.
- Physical Examination: Assessing for signs of liver failure, such as jaundice, ascites, and encephalopathy.

Laboratory Tests

Key laboratory tests are essential for diagnosing and monitoring the severity of liver failure:
- Liver Function Tests: These include measurements of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, and bilirubin levels.
- Coagulation Profile: Prothrombin time (PT) and international normalized ratio (INR) are critical for assessing liver synthetic function.
- Electrolytes and Renal Function: Monitoring for complications such as renal failure is also crucial.

Supportive Care

Hospitalization

Patients with acute hepatic failure typically require hospitalization, often in an intensive care unit (ICU) setting, for close monitoring and management of complications.

Nutritional Support

Nutritional support is vital, as patients may have increased metabolic demands and risk of malnutrition. Enteral feeding is preferred when possible, with careful monitoring of protein intake to manage hepatic encephalopathy.

Fluid and Electrolyte Management

Maintaining fluid balance and correcting electrolyte imbalances are essential components of supportive care. This may involve intravenous fluids and careful monitoring of renal function.

Specific Treatments

Addressing the Underlying Cause

Identifying and treating the underlying cause of hepatic failure is crucial. This may include:
- Antiviral Therapy: For viral hepatitis, appropriate antiviral medications may be initiated.
- Discontinuation of Offending Agents: If drug-induced liver injury is suspected, stopping the offending medication is critical.

Management of Complications

Patients may develop complications such as:
- Hepatic Encephalopathy: Managed with lactulose or rifaximin to reduce ammonia levels.
- Coagulopathy: May require vitamin K administration or fresh frozen plasma transfusions if bleeding occurs.

Advanced Therapies

Liver Transplantation

In cases of severe acute hepatic failure where there is a high risk of mortality, liver transplantation may be the only definitive treatment. Criteria for transplantation include:
- Fulminant Hepatic Failure: Patients with grade III or IV hepatic encephalopathy or those who do not improve with medical management.
- Model for End-Stage Liver Disease (MELD) Score: A MELD score greater than 30 often indicates the need for urgent transplantation.

Artificial Liver Support Systems

In some cases, patients may benefit from artificial liver support systems, such as:
- Molecular Adsorbent Recirculating System (MARS): This system helps to remove toxins from the blood, providing temporary support while awaiting liver recovery or transplantation.

Conclusion

The management of acute and subacute hepatic failure (ICD-10 code K72.0) is multifaceted, focusing on stabilization, supportive care, and addressing the underlying cause. Early recognition and intervention are critical to improving outcomes. In severe cases, liver transplantation may be necessary, highlighting the importance of a timely and coordinated approach among healthcare providers.
