Brief summary
Critical care patients experience systemic aggression, which may be the result of trauma, infection or other systemic inflammatory mechanisms. The initial phase of their illness is characterized by metabolic instability and increased catabolism. Nutrition goals in these patients are therefore, on the one hand, to provide sufficient caloric intake to cover energy expenditure while limiting the risks of inappropriate under-feeding, overfeeding- or re-feeding syndrome, and on the other hand, to meet the protein requirements linked to hypercatabolism. In the absence of contraindication, current recommandations state that an intensive care patient who cannot be fed orally, shoul receive continuous enteral nutrition over 24 hours by gastric tube within 48 hours of admission. However, this 24-hour continuous nutrition method does not correspond to the physiological habit of the human species which includes a physiological nighttime fasting period.This fasting period induces a metabolic switch that regulates several pathways, including glycemic control, oxidative stressresistance and deoxyribonucleic acid (DNA) repair. Furthermore, it takes part un the synchronization of cellular circadian rhythms. Investigator hypothetises that diurnal cyclic enteral nutrition may improve the prognosis of severe intensive care patients compared to continuous enteral nutrition.
Interventions
OTHERday time cyclic nutrition
Continuous isocaloric enteral feeding (1kcal/ml) with 4g of protein per 100 mL for 10 hours during the day (e.g. 08:00 to 18:00), via nasal or oro-gastric tube
OTHERcontinuous nutrition
Isocaloric enteral feeding (1kcal/ml) with 4g of protein per 100ml, continuously 24 hours a day by nasal or oro-gastric tube
