Abstract

Background: Enteral nutrition is a major pathway of nutrition for patients requiring critical care. However, it remains unclear whether intermittent or continuous feeding is the better approach, especially after nasogastric enteral nutrition via a gastric tube. Therefore, this randomized controlled clinical study was designed to observe the effects of different methods on critically ill patients.

Methods: Different Feeding Methods on Gastrointestinal Function of Critical patients (DFM-GFC) is a randomized clinical study that will be performed to assess the effects of three feeding methods on critically ill patients. A total of 90 critically ill patients will be equally randomized into three groups: continuous feeding, cyclic feeding, and intermittent feeding. The patients will be administered a gastrointestinal nutrition preparation over 24 h via a gastric tube or over 16 h via an intermittent pump. The primary outcome is the mean duration (days) to reach the caloric goal in each group. Secondary outcomes include the rate of onset of gastric residual, abdominal pressure, the rate of onset pneumonia, and the proportion of individuals achieving the caloric goal. Additionally, the length of intensive care unit (ICU) stay and mortality rate at 28 days post-enrolment will be evaluated.

Discussion: This study will observe the effects of different feeding methods on various parameters, such as the energy target and gastrointestinal motility, in critically ill patients to improve quality of life and reduce the case fatality rate. The purpose of this study is to explore whether there is a more effective, safer and cost-efficient feeding method for the clinical treatment of critically ill patients.
