Abstract
Burns cause massive dermal wounds. Wound healing elicits a significant catabolic response and increase in energy expenditure, and thus, calorie needs. Research shows that overfeeding and underfeeding the obese critically ill patient is associated with an increase in complications such as longer time on mechanical ventilation, delayed wound healing and longer length of stay in the hospital. Predictive equations are utilized to estimate energy expenditure to determine enteral and/or parenteral regimens in these patients. Adequate provision of energy is vital to help optimize healing. Indirect Calorimetry (IC) is considered the ‘gold standard’ tool for measuring energy expenditure. However, due to its expense, IC is not always available. Thus, predictive equations are used instead. Currently, there is a gap in the literature regarding how valid predictive equations are for estimating energy expenditure in obese burn patients compared to energy expenditure as measured by IC. The current research aims to address how energy needs as calculated/estimated by the Curreri predictive equation compares to energy needs as measured by IC in overweight and obese adult burn (>20% TBSA) patients.
