Parenteral nutrition in liver failure and hepatic encephalopathy



This calculator is a work in progress. Please double check the results

The ideal nutrition in decompensated liver cirrhosis and hepatic encephalopathy is a controversial topic. The approach here is largely based on a German guideline from 2009, although other guidelines support the suggested protein and energy intake. This approach here assumes, that you have three components to your parenteral nutrition:

  • a protein (or amino acid) component
  • a lipid component
  • a glucose component

In order to calculate the correct rates, you might need to adjust the parameters (e.g. energy contents or concentrations). Preset are values for an 8 % amino acid component, a 40 % glucose component and a 2000 kcal/l lipid component
