Hormonal and metabolic changes following severe head injury or noncranial injury.
Journal of Parenteral and Enteral Nutrition
In order to evaluate the effect of head injury in severely traumatized patients on the response of plasma cortisol, glucagon, insulin, glucose, and FFA as well as urinary N and catecholamines excretions, 36 patients were prospectively studied over 5 consecutive days following injury. They were divided into three groups: group I, severe isolated head injury (n = 14); group II, multiple injury combined with severe head injury (n = 12); group III multiple injury without head injury (n = 10). The results demonstrate similar hormonal and metabolic changes between these three groups of patients, characterized by elevated urinary adrenaline, noradrenaline excretion, increased cortisol, glucagon, insulin plasma levels throughout the study and elevated N urinary excretion with strongly negative N balances during the first 5 days postinjury. A significant correlation was observed between N intake and 5 day cumulated N balance (r = 0.63, p less than 0.001). In addition, N balance was negatively correlated with urinary excretion of adrenaline (r = -0.47, p less than 0.01) and noradrenaline (r = -0.44, p less than 0.05) as well as plasma levels of glucagon (r = -0.44, p less than 0.05). Isolated severe head injury seems to induce a full response in the secretion of the catabolic counterregulatory hormones comparable to that encountered in patients with multiple injury and associated with a marked increase in protein catabolism; additional noncranial major injury does not seem to enhance these responses.
