Explain Metabolic Response to Injury?
There is an increase in the basal metabolic rate above the normal. The degree of hyper metabolism is related to the severity of the injury. Long-time fracture usually result in a 15 to 25% increase in metabolic rate, multiple injuries increase metabolic rates by 50% and severe burn patients have metabolic rates raised by 100%. The body temperature of a trauma patient rises by 1-2°C due to an upward shift in the thermoregulatory set point of the brain. The changes in glucose, protein and fat metabolism are being discussed below.
