Key to the management of encephalopathy is identifying and then eliminating whatever precipitating factors are responsible. Dietary protein should be restricted, infections should be treated, all sedatives should be discontinued, and intestinal catharsis should be accomplished.
Pharmacologic treatment of encephalopathy is indicated for patients with chronic, intermittent symptoms and for those with persistent, acute psychoneurologic disturbances despite elimination of precipitating factors. The only drugs with proven effectiveness are neomycin, a poorly absorbed antibiotic that suppresses ureasecontaining bacteria, and lactulose, a nonabsorbable disaccharide that acidifies colonic contents and also has a cathartic effect Unproven therapies for encephalopathy include the enteral or parenteral administration of branched-chain amino acids and the drug flumazenil, a selective antagonist of benzodiazepine receptors
