[Consistency study of indirect calorimetry and HB equation for measuring energy expenditure of patients with multiple injury receiving mechanical ventilation].

Objective: To evaluate the difference and correlation of 24-hour energy expenditure in patients with multiple trauma receiving mechanical ventilation predicted by indirect calorimetry (IC) and HB formula.

Methods: 140 patients with multiple trauma receiving mechanical ventilation admitted to intensive care unit (ICU) of the General Hospital of Ningxia Medical University from December 1st, 2016 to August 31st, 2017 were enrolled. The 24-hour energy expenditure of patients was repeatedly measured at 1, 3, 5, and 7 days after ICU admission by IC method, and the 24-hour energy expenditure measured by IC method was used as the "gold standard" to calculate the 24-hour kilogram body weight energy expenditure.
