Hepatic coma

Hepatic coma represents the most severe, life-threatening stage (Grade IV) of hepatic encephalopathy, characterized by profound central nervous system depression, complete loss of consciousness, and unresponsiveness to external stimuli

Hepatic coma represents the most severe, life-threatening stage (Grade IV) of hepatic encephalopathy, characterized by profound central nervous system depression, complete loss of consciousness, and unresponsiveness to external stimuli This neuropsychiatric complication primarily affects patients with acute liver failure, end-stage chronic liver disease or cirrhosis, or significant portosystemic shunting

Hepatic coma represents the most severe, life-threatening stage (Grade IV) of hepatic encephalopathy, characterized by profound central nervous system depression, complete loss of consciousness, and unresponsiveness to external stimuli Pathophysiologically, severe hepatic dysfunction and the bypass of portal blood flow permit circulating neurotoxins—predominantly ammonia—to cross the blood-brain barrier
