[Glucose tolerance test and some pathways of glucose metabolism in patients with craniocerebral trauma].
Intravenous glucose tolerance test was done and concentrations of lactic acid and pyruvic acid were determined together with the lactic acid/pyruvic acid index and lactic dehydrogenase activity in fasting venous blood and 35 and 90 min. after glucose load. The investigations were carried out in 30 patients with cerebral concussion and 20 patients with cerebral contusion on the 1st, 3rd and 7th days after trauma. Thirty healthy subjects served as controls. Presence of hyperglycaemia in fasting state and impairment of glucose tolerance were demonstrated in the first week of the disease. These disturbances were accompanied by significant decrease of the activity of lactic and pyruvic acid metabolism during the first three days after trauma. The values of lactic acid/pyruvic acid index and LDH activity were not changed significantly. Disturbances of carbohydrate metabolism persisted during the first week after trauma and were more frequent, more intense and persisted longer in patients with brain contusion than in those with brain concussion but showed no significant differences related to the degree of trauma.
