Jeschke et al1 showed that increasing enteral nutrition could ameliorate the adverse hypermetabolic consequences of thermal injury in their rat model. The rat gut better tolerates major insults than the more fragile human intestinal tract. However, despite species differences, there is good reason to believe that humans respond similarly to hypermetabolic stresses.
