HEPATIC COMS Flashcards
explain HEPATIC COMA
● Protein in your diet is broken down into ammonia.
● Liver is supposed to convert the ammonia into urea.
○ Kidneys can excrete urea.
● When there is inflammation of the liver due to hepatitis, the ammonia builds
up instead of being converted to urea
● Increased ammonia levels can cause a hepatic coma.

treatment for hepatic coma
● Lactulose
● Cleansing enema

○ Allows the ammonia to be excreted decreasing serum ammonia
