Energy Metabolism Following Head Injury

摘要: It is well known that severe trauma induces profound physiologic changes with marked hormonal, metabolic, circulatory, respiratory and immunological modifications. The hormonal response characterized by alteration of pituitary hormone secretion, activation the sympatho-adrenal system elevation in counterregulatory hormones secretion [1]. In addition, clinical biochemical evidences a typical acute phase are present [2]. metabolic include resting rate, an increased mobilization amino-acids from body tissues, as rise urinary nitrogen excretion [3]. A negative balance often observed despite apparently adequate nutritional supply [4, 5].
