Effect of indirect calorimetry on early enteral nutrition in patients undergoing mechanical ventilation

Abstract

Objective To analyze the application value of indirect calorimetry in early enteral nutrition nursing care of mechanical ventilation patients. Methods The data of 62 patients treated with mechanical ventilation at our hospital from September, 2017 to September, 2018 were retrospectively analyzed. The patients were randomly divided into a study group and a control group, 31 cases for each group. The two groups were given early enteral nutrition and routine nursing care; in addition, the study group carried out the nursing mode supported by indirect calorimetry. The serum nutritional indicators and physical changes were compared between the two groups. Results On the 1st day, there were no statistical differences in serum albumin, hemoglobin, total protein, muscle circumference of upper arm, and skin fold thickness of triceps between the study group and the control group (all P>0.05). On the 7th day, the serum albumin, hemoglobin, and total protein as well as the muscle circumference of upper arm, and skin fold thickness of triceps were (37.94±3.59) g/L, (21.28 ±4.29) g/L, (65.67±4.26) g/L, (26.04 ±3.27) cm, and (13.05 ±1.89) cm in the study group, respectively, which were better than those in the control group (all P<0.05). Conclusion According to indirect calorimetry, early enteral nutrition in mechanical ventilation can promote the recovery of nutritional indicators, correct malnutrition, and promote the metabolic function of patients, and has clinical application value.
