Hepatitis is a common viral infection in the hospital population, especially with liver failure patients. There are a variety of strains of hepatitis, some acute and some chronic in nature. The most common type that I have seen in the ICU is Hepatitis C with chronic liver disease patients. When patients are in the ICU, their liver failure is generally very advanced requiring more palliative treatment. What causes this destruction of the liver? How do we prevent this from happening?
