Summary

Continuous feeding is the most popular enteral feeding mode in the ICU because of its lower nursing burden and theoretically better intestinal toleration. However, continuous feeding is nonphysiological. We proposed a feeding mode called sequential feeding, as it utilizes a combination of continuous feeding in the beginning, time-restricted feeding in the second stage, and oral feeding at last.

The gut microbiota plays a critical role in human health due to its many useful functions. Not only dietary structure but also eating mode (eating time for example) influenced the gut microbiota in a healthy population. Therefore, we think this new feeding mode, sequential feeding, also has different influences on gut microbiota and metabolomics in critically ill patients compared to continuous feeding.

Interventions

BEHAVIORAL

continous feeding

At the beginning, all the patients received continuous feeding. After achieving ≥80% of the nutrition target calories (25-30 kcal/kg/d) through continuous feeding, the patients were randomly assigned into the sequential feeding (SF) group or the continuous feeding (CF) group with a random number table. Patients in the CF group received continuous feeding with constant velocity by enteral feeding pump over one day.

BEHAVIORAL

sequential feeding

At the beginning, all the patients received continuous feeding. After achieving ≥80% of the nutrition target calories (25-30 kcal/kg/d) through continuous feeding, the patients were randomly assigned into the sequential feeding (SF) group or the continuous feeding (CF) group with a random number table. In the SF group, continuous feeding was changed into time-restricted feeding. The total daily dosage of enteral nutrition was equally distributed during three time periods at 7-9:00, 11-13:00 and 17-19:00. Other times of the day were fasting times. Enteral nutritional suspension in each time period was administered at a uniform rate within two hours by an enteral feeding pump.
