Energy expenditure in severe sepsis or septic shock in a Thai Medical Intensive Care Unit.

Background And Objectives: Energy expenditure in severe sepsis/septic shock patients was measured by indirect calorimetry and the correlation of energy expenditure between indirect calorimetry and predictive equations was determined.

Methods And Study Design: This was a prospective, observational analytical study. Severe sepsis or septic shock patients were measured for energy expenditure over 72 hours by indirect calorimetry that was measured by a mechanical ventilator (EngströmCarestation, GE Healthcare).
