title: [Barbiturate infusion in severe brain trauma (preliminary report) (author's transl)].
abstract: The pathophysiology of brain trauma regarding disturbances of energy and transmitter metabolism, development of intra- and extracellular cerebral oedema are briefly outlined. Possible mechanisms of action of barbiturates in amelioration of cerebral ischaemia, decrease of cerebral metabolism, preservation of membrane stability, reduction of cerebral oedema and intracranial pressure are reviewed. We report on 6 patients with severe brain trauma due to head injury whose intracranial pressure despite conventional treatment with hyperventilation, steroids and osmotic diuresis remained above 25 mm Hg. They were infused with thiopentone 6--12 mg/kg x h for 6 to 15 days, to reduce cerebral electrical activity to the point of "burst suppression" in the electroencephalogram. Three patients survived, two of them regaining their previous good health. The results in these patients are discussed as regards thiopentone dosage and severity of trauma. Marked cardiovascular instability in one case and cholostatic jaundice due to barbiturate administration in two cases were the most important side effects. Barbiturate infusion seems to be indicated in brain trauma with sustained elevation of intracranial pressure above 25 mm Hg despite vigorous conventional therapy. Monitoring most essential to this aggressive treatment scheme comprises measurement of intracranial pressure and continuous observation of the EEG.
