Comparison of Time-restricted Feeding and Continuous Feeding in Critically Ill Patients

May 30, 2020 updated by: Bo Yao,phD, Qingdao University

In the nutrition guideline (A.S.P.E.N guideline), there was no recommendation about the feeding type in enteral feeding of critically ill patients. Continuous feeding is the most popular feeding type in ICU because of its less nursing burden and reducing the aspiration incidence theoretically. However, some previous studies demonstrated that there were no complications differences between continuous and time-restricted feedings(such as intermittent feedings).

In ICU, the disorder of protein synthesis is a universal problem and is associated with ICU acquired weakness. Time-restricted feeding is more physical than continuous feeding. In some animal researches, time-restricted feeding was proved to have a greater stimulatory effect on protein synthesis than continuous feeding. Besides of light, time-restricted feeding can may also adjust the biological rhythms. It is known that biological clocks could affect energy metabolism, emotion and so on. Until now, there are no enough clinical studies to prove the advantages in time-restricted feeding in ICU patients.So researchers designed the study to compare the time-restricted feeding and continuous feeding effect(especially protein synthesis) on ICU patients.

Detailed Description

Enteral nutrition support can be administered by continuous administration or by time-restricted administration in ICU. Continuous feeding is the most popular feeding schedule because of its less nursing burden and reducing the aspiration prevalence theoretically. However, previous studies demonstrated that there was no complications (diarrhea, distension, Ventilator associated pneumonia-VAP incidence, and so on) difference between these two feeding schedule. So in the nutrition guideline (A.S.P.E.N guideline), there was no recommendation about the feeding schedule. However, time-restricted feeding is more physical than continuous feeding. In ICU, the disorder of protein synthesis is a universal problem and is associated with ICU acquired weakness. In some animal researches, time-restricted feeding was proved to have a greater stimulatory effect on protein synthesis than continuous feeding.

Besides of light, time-restricted feeding can adjust the biological rhythms. It is known that biological clocks could affect energy metabolism, emotion and so on. In the "zi wu liu zhu" theory of traditional chinese medicine, feeding time should be at 7:00-9:00, 11:00-13:00 and 17:00-19:00. So researchers designed the study to compare the time-restricted feeding according to traditional chinese medicine and continuous feeding effect(especially protein synthesis) on ICU patients.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: continuous feeding
The total amount of every days' Enteral Nutritional Suspension was fed at constant speed for 24h
At the beginning, all enrolled patients were fed by continuous feeding. When the amount calorie of feeding enteral nutritional suspension increased to 80% target calorie (target calorie: 25kilocalorie/kg.d), the patients was randomly into continuous feeding and time-restricted feeding group.In the continuous feeding, the total amount of every days' Enteral Nutritional Suspension was fed at constant speed for 24h.
Other: time-restricted feeding
The total amount of every days' Enteral Nutritional Suspension was fed at constant speed for 6h (7:00-9:00,11:00-13:00,17:00-19:00).
At the beginning, all enrolled patients were fed by continuous feeding. When the amount calorie of feeding enteral nutritional suspension increased to 80% target calorie (target calorie: 25kilocalorie/kg.d), the patients was randomly into continuous feeding and time-restricted feeding group. In continuous feeding group, the enteral nutritional suspension was fed at constant speed for 24h.In the time restricted feeding, feeding time should be at 7:00-9:00, 11:00-13:00 and 17:00-19:00 at constant feeding speed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
nitrogen balance
Time Frame: at the time point of 10th feeding day
it equal to Nitrogen intake minus Nitrogen output.Source of nitrogen intake is the enteral nutritional suspension, and the amount of nitrogen can be calculated according to the proportion of nitrogen in enteral nutritional suspension. Main nitrogen losses include urine and feces. The amount of nitrogen in urine and feces can be measured by clinical laboratory.
at the time point of 10th feeding day

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
delirium
Time Frame: up to 10 days
it is disorders of the mental state and medical condition. It can be evaluated by The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).
up to 10 days
Gastric residual volume
Time Frame: up to 10 days
This index was to evaluate the feeding complications. Nurse can evaluate the volume by pumping the stomach tube with syringe to measure the gastric content amount.
up to 10 days
diarrhea
Time Frame: up to 10 days
This index was to evaluate the feeding complications. It is the condition of having at least three loose or liquid bowel movements each day.
up to 10 days
Incidence of ventilator-associated pneumonia
Time Frame: up to 10 days
This index was to evaluate the feeding complications. Ventilator-associated pneumonia (VAP) is a type of lung infection that occurs in people who are on mechanical ventilation breathing machines for at least 48 hours. The diagnosis of VAP varies among hospitals and providers but usually requires a new infiltrate on chest x-ray plus two or more other factors. These factors include temperature of >38 or <36 °C, a white blood cell count of >12 × 10^9/ml, purulent secretions from the airways in the lung, and/or reduction in gas exchange.
up to 10 days
glucose fluctuation
Time Frame: up to 10 days
This index was to evaluate the feeding complications. The glucose is measured at the 11:00, 15:00, 21:00, 1:00 and 5:00 five time points. The glucose fluctuation is the maximum glucose amount plus minimum glucose amount.
up to 10 days
Albumin
Time Frame: up to 10 days
Serum albumin is the main protein of human blood plasma. It can be measured by clinical laboratory.
up to 10 days
