IRCT20120525009856N6 IRCT 2018-03-26 Kermanshah University of Medical Sciences The effect of calorie intake on Intensive Care Unite patients comparative clinical outcome in Hypocaloric vs. Fullcaloric Enteral feeding during the first week of Hospitalization in Intensive Care Unite Patients 2018-03-30 anticipated 70 Complete https://irct.ir/trial/28712 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, patients will be divided into two groups of hypocaloric and full-calorie diet by using Stratified blocked randomization, so that two groups will not have a significant difference in terms of gender, age, body mass index and severity of illness, Blinding description: Double-blinded method will be used in order to prevent incidence of information bias, in such a way that after calculating required energy for patient, a code will be given to the subject. Afterwards, the patient will be enter into one of the two groups of intervention and control group, based on the attained code through randomized classified method. N/A Patients of intensive care unit. Intervention 1: Intervention group: Patients in the intervention group will receive Hypocaloric diet. After hemodynamic stabilization, enteral nutrition support will be started during the first 24-48 hours that individual will be inpatient, and will be prescribed in form of bolus every three hours (6 times in 24 hours). Subjects of hypocaloric diet group will receive 40 percent of calculated calorie by using indirect calorimetry device during the first 24-48 hours of being in patient, and this amount will be reach to100 percent of patient’s need in one week. This group will be fed exactly similar to control group by full-calorie method after 7 days of intervention. Intervention 2: Patients of first group that defined as control group, which is the full-calorie group, will receive 80 to 100 percent of their actual energy requirement as nutrition support in form of enteral method that will be started during the first 24-48 hours of being inpatient. The required calorie will be calculated through indirect calorimetry and intervention will be continued for 7 days.
