Introduction
The aim of the ESPEN guidelines on enteral
nutrition (EN) is to evaluate the evidence on EN in
different indications and serve as orientation tools
for distinct decisions in clinical practice. Therefore,
the single chapters focus on specific questions
relevant to the respective indication. More general
questions, which might be important in all or
several indications are dealt with in this introductory
chapter to avoid repetition. Furthermore, the
terminology and definitions used throughout these
guidelines are also explained in this chapter.
