To reduce blood ammonia can be used in the following ways: 1, the use of menadione ornithine, the drug can accelerate the conversion of blood ammonia into urea, thus rapidly reducing blood ammonia concentration. 2, to promote the discharge of ammonia in the intestine, reduce the absorption of ammonia, you can reduce the absorption of ammonia in the intestinal tract through oral lactulose oral solution, lactitol, or rhubarb powder, lactulose enema, through multiple defecation. 3, you can use antibiotics to Inhibit the growth of intestinal bacteria to reduce the production of ammonia by intestinal bacteria. 4. Dilute acetic acid can be used for enema to acidify the intestinal tract and promote the conversion of blood ammonia into ionic ammonia NH4, which does not pass the blood-brain barrier and has no toxic effect on brain cells, thus improving hepatic encephalopathy.
