Definition

Noun A state of deep unconsciousness that can occur as a severe complication of advanced liver disease. It is caused by the liver's inability to remove toxins, especially ammonia, from the blood, which then accumulate and impair brain function.

Usage

This is a medical term used specifically in clinical and healthcare contexts to describe a serious neurological condition resulting from liver failure.

Examples

• The patient was admitted to the intensive care unit in a hepatic coma.
• The primary goal of treatment is to reverse the factors that precipitated the hepatic coma.
• Advanced cirrhosis can lead to complications such as hepatic coma.

Advanced Usage

• The term is often used in discussions of the stages of hepatic encephalopathy, with coma representing the most severe stage (Stage 4).
• It may be specified further based on the underlying cause, e.g., a hepatic coma due to acute liver failure versus chronic liver disease.

Variants and Related Words

• Coma (n): A state of prolonged unconsciousness from which a person cannot be awakened, caused by various factors including trauma, illness, or toxin accumulation.

Synonyms
