Comparison of Time-restricted Feeding and Continuous Feeding in Critically Ill Patients
A study testing time-restricted feeding and continuous feeding in people with Feeding Behavior, run by Qingdao University at 1 site in China.
Trial summary
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. Read more about this study

About this study
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
time-restricted feedingOther
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.
continuous feedingOther
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.
| Study group | Role | What they receive |
|---|---|---|
| continuous feeding | Other | The total amount of every days' Enteral Nutritional Suspension was fed at constant speed for 24h Receives: Other: continuous feeding |
| time-restricted feeding | Other | 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). Receives: Other: time-restricted feeding |
What is being measured
The primary outcome is the main question the study is designed to answer.
nitrogen balance
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.
Measured: at the time point of 10th feeding day
Secondary outcomes (6)
delirium
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).
Measured: up to 10 days
Gastric residual volume
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.
Measured: up to 10 days
diarrhea
This index was to evaluate the feeding complications. It is the condition of having at least three loose or liquid bowel movements each day.
Measured: up to 10 days
Incidence of ventilator-associated pneumonia
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.
Measured: up to 10 days
glucose fluctuation
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.
Measured: up to 10 days
Albumin
Serum albumin is the main protein of human blood plasma. It can be measured by clinical laboratory.
Measured: up to 10 days

Questions about this trial
What is this clinical trial studying?
A study testing time-restricted feeding and continuous feeding in people with Feeding Behavior, run by Qingdao University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 2 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Bo Yao, PHD (+86053282912221, icuyaobo@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
nitrogen balance (time frame: at the time point of 10th feeding day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03439618, which also lists 8 linked publications.
