[Prevention of hepatic encephalopathy].

Hepatic encephalopathy (HE) is a frequent complication of cirrhosis which, in addition to producing a great social impact, deteriorates the quality of life of patients and is considered a sign of advanced liver disease and therefore a clinical indication for liver transplant evaluation. Patients who have had episodes of HE have a high risk of recurrence. Thus, after the HE episode resolves, it is recommended: control and prevention of precipitating factors (gastrointestinal bleeding, spontaneous bacterial peritonitis, use of diuretics with caution, avoid nervous system depressant medications), continued administration of non-absorbable disaccharides such as lactulose or lactitol, few or non-absorbable antibiotics such as rifaximin and assess the need for a liver transplant as the presence of a HE episode carries a poor prognosis in cirrhosis.
