[The utilization of nutrient substances during wound healing].

[Article in Russian]

Abstract

The process of wound healing represents a series of complex physicochemical reactions requiring different nutritional microcomponents at each stage. In patients with extremely grave diseases and injuries the course of wound healing is impaired because of a hypermetabolic reaction to stress, leading to protein catabolism. The hypothalamus responds to cytokine stimulation by changes of thermoregulation (increase of heat production) and increased production of stress hormones (catecholamines, hydrocortisone, and glucagon). In turn, stress hormones trigger the thermogenous (unproductive) metabolic cycle and the lipolysis and proteolysis processes. Hyperproduction of glucose at the expense of skeletal muscle tissue degradation leads to the formation of amino acid substrate for liver glyconeogenesis. Additional nutrients are obligatory for wound healing in such patients. Protein catabolism cannot be arrested by amino, acids alone partly because amino acid transport is impaired; it can be normalized by anabolics, such as growth hormone and insulin-like growth factor 1. Treatment with growth hormone yields a dramatic positive effect in severely burned children. Proteins and vitamins, specifically arginine and vitamins A, B, and C provide the optimal nutritive support during wound treatment.
