[Serum enzymes in seriously injured patients].

In 45 patients with multiple injuries due to trauma, admitted consecutively to our clinic, the following enzyme activities were studied, beginning at the onset of treatment: SDH, GPT, GLDH, and acid phosphatase. The mean levels of SDH rose in all patients between 2 and 24 h after trauma. The mean values of GPT were above normal between 2 and 48 h after trauma; this rise was more pronounced and statistically significant in those patients who eventually died of trauma than in the less severely injured ones. Twenty-four hours after trauma, the levels of GLDH were 16 times higher in the first group of patients than in the less severely injured group. These results lead us to the conclusion that through serum level measurements of these enzymes particularly of GPT it is possible to evaluate the degree of tissue damage and the general state of this group of patients.
