Nutrition is crucial factor in maintaining burn Healing of burn wounds Excessive energy demands during the burn wound healing process should be met with proper nutrition. Nutritional deficits obstruct the natural processes that allow wound healing to go through particular stages. Aim: To assess the effect of nutritional factor on burn wound healing. Research question: Does the nutritional factor affect on burn wound healing. Methods: Descriptive exploratory design was conducted on thirsty adult patients, aged from 18-65 years admitted to the burn unit at El Elman General Hospital & General Assiut hospital. Tools :( 1) Patient assessment sheet. (2) The Bates-Jensen Wound Assessment Tool is a tool for assessing wounds (BWAT). Results: A negative relationship was found between burn wound severity and clinical nutritional parameters as (-.664,-.579,-.621, -.752, -.777|) respectively. Conclusions: a deterioration in burn wound condition from minimal to moderate and extreme severity was observed among studied patients with reduction of the nutritional factor. Recommendation: Nutritional elements must be provided for burned patients during all phases of burn wound healing process.
