Undiluted and Diluted Nutrition

Adult patients after elective major abdominal surgeries who are planned to be admitted to the Intensive Care Unit (ICU) can be included in the trial. Each patient will be fed via the gastrointestinal tract. Half of the patients will receive enteral nutrition (EN) with additional fluids, and the rest will receive undiluted EN. The primary aim of this study is to assess feeding intolerance in both patient groups.
