Time-related variations of some biochemical parameters in patients with short- or long-lasting post-traumatic coma.

The variation in time of some blood biochemical parameters was investigated in 100 patients with acute head injury and coma of variable duration, in parallel with the clinical course. The purpose of this study was to establish possible correlations between the severity of the trauma (assessed according to the coma classification proposed by C. Arseni) and the variation of the parameters studied.
