RÉSUMÉ
As the significance of nutrition in intensive care unit grows, large prospective randomized controlled trials on nutrition therapy have been performed and recently published. Each society for Parenteral and Enteral Nutrition designated recommendations for clinical practice based on the best available evidence and the consensus of experts. The European Society for Parenteral and Enteral Nutrition (ESPEN) has released a new guideline that has been updated from the previous ESPEN guidelines on enteral nutrition and parenteral nutrition in adult critically ill patients published in 2006 and 2009, respectively. This study examined the latest trends of nutrition guidelines, and especially those of the ESPEN 2018, for intensive care units as compared to guidelines of other societies and older previous guidelines.
