Medical Care
- No specific therapy is available for either fulminant hepatic necrosis or mild hepatotoxicity due to halothane. Only supportive therapy and orthotopic liver transplantation are available for hepatic necrosis.
- Because halothane hepatitis is a diagnosis of exclusion, ruling out other causes is essential.
- As in any form of fulminant hepatitis, take the following measures when instituting supportive therapy:
- Maintain fluid and electrolyte balance.
- Support hemodynamics as necessary.
- Support ventilation as necessary.
- Correct any alterations in coagulation.
- Correct hypoglycemia.
- Treat any other complications of the comatose state.
- Restrict protein intake and administer oral lactulose or neomycin.
- High-dose corticosteroid therapy has been used in liver failure but has been shown ineffective in controlled trials.
- Molecular adsorbent recirculating system (MARS) is a safe temporary life support mechanism for patients awaiting liver transplantation or recovering from fulminant hepatic failure.
- A recent animal study concluded that zinc has the potential to alleviate halothane-toxic effects in the liver of rats by demonstrating a reduction of hepatic enzyme levels and reduction in liver damage in the zinc-halothane group. Further translational studies are warranted.[4]
Surgical Care
- If fulminant liver failure occurs and liver function does not recover, orthotopic liver transplantation has been a successful option and may be considered.
Consultations
- Consult with a hepatologist for assistance in confirming the diagnosis.
- Consult with a critical care specialist for support of metabolic, respiratory, and cardiovascular issues.
- Consult with organ procurement team and transplant teams, including transplant surgeon, if liver failure is imminent.
Diet
Restrict protein intake and administer oral lactulose or neomycin.
Activity
Although bed rest is not essential for full recovery, many patients feel better with restricted physical activity.
