[Effects of early supplemental parenteral nutrition on nutrition intakes and clinical outcomes in trauma patients].

Objective: To evaluate energy and protein intake changes in early supplemental parenteral nutrition (PN) in trauma patients, and to assess its impact on clinical outcomes.

Methods: Clinical results of patients receiving or not receiving additional PN during the first 7 days after injury were retrospectively analyzed, with a total of 195 patients classified into two groups: control group (n=105) and mixed nutrition group (n=90). The time of nutrition support, intakes of protein and energy within 14 days after trauma, and clinical outcomes were compared between two groups.

[Analysis of energy balance and risk factors on clinical outcomes in patients with severe traumatic brain injury].

Objective: To observe the energy expenditure in severe traumatic brain injury patients, and to assess the impact of cumulative energy balance on clinical outcomes.

Methods: Using prospective self-controlled study, the change in energy expenditure of 42 patients with severe traumatic brain injury was measured by indirect calorimetry (IC). Daily energy intake was recorded.

[Comparison of measuring energy expenditure with indirect calorimetry and traditional estimation of energy expenditure in patients in intensive care unit].

Objective: To compare measurement of energy expenditure (MEE) by indirect calorimetry (IC) with traditional estimation of energy expenditure (EEE), to provide a basis for energy supplementary for critically ill patients.

Methods: Using self-controlled study,the energy expenditure of 57 intensive care unit (ICU) patients was measured by IC. Meanwhile, EEE was also calculated using the following equations : Harris-Benedict (HB), HB×factor , or 104.
