Further research is needed to determine if differing types of carbohydrates can be used as energy fuel substrates for wound healing. Varying the absolute level of carbohydrate intake has been studied, with levels as much as 82% of total calories being acceptable. In addition, determining the timing of nutrition intervention and the route of administration continue to be challenges in patients needing critical care and in those requiring chronic wound care. Further research into alternate nutritive sources may also be useful.
