To evaluate the profile of plasma catecholamine concentrations and sympathetic nervous system activation over an eight-day period following severe multiple trauma.
Prospective study of 45 severely injured patients categorized into critically injured (N=16) and seriously injured (N=29) groups.
Serial measurements of plasma adrenaline and noradrenaline concentrations were obtained upon admission and monitored over an 8-day observation period.
Total plasma catecholamines on admission were nearly two-fold higher than day 8 baseline values and remained significantly elevated for 6 hours post-trauma.
Admission plasma adrenaline correlated with blood volume replacement needs during the initial 6 hours, with elevated levels differentiating critical from serious injury for the first 12 hours.
Plasma noradrenaline levels remained significantly higher in critically injured patients compared to seriously injured patients throughout the entire 8-day monitoring period.

Implication

Prospective study demonstrates elevated plasma catecholamines in severely injured patients, indicating intense sympathetic activation driven by shock, tissue hypoxia, and trauma.
