Despite advancements in pediatric burn care, the profound hypermetabolic response associated with severe burns remains a multifaceted challenge throughout the continuum of care. Understanding the various physiologic disturbances that constitute hypermetabolism is crucial for a thorough evaluation and for implementing appropriate surgical and nonsurgical interventions. In this article, we describe the pathophysiology and treatment of hypermetabolism in pediatric burn patients with a focus on reducing resting energy requirements, minimizing infection, and optimizing nutrition for patients undergoing frequent surgical intervention.
