title: [The E.E.G. in ruptured cerebral aneurysms before operation. Use of carotid compression and the controlled hypotension test (author's transl)].
abstract: In 45 cases of ruptured intra-cranial aneurysms the authors studied the standard E.E.G. data under carotid compression and controlled hypotension; the changes observed were analysed and their value assessed for judging the state of the patient's cerebral circulation. A normal resting E.E.G. carries a good prognosis. Carotid compression and controlled hypotension provide a useful assessment of the supply and elasticity of the cerebral vessels; the occurrence of slow waves during controlled hypotension is an alarm signal which often helps in anaesthetic procedure.
