[Effects of Alfatesin on total cerebral blood flow in humans].
The total cerebral blood flow was measured by the Xe 133 in 9 patients, before and during a pure Alfatesine induced anaesthesia. With a perfusion flow of 0,04 ml/kg/mn, the total flow underwent a mean fall of 38 p. 100 that was linked neither to any systemic pressure variations nor to variations of the PaCO2. This fall was linked to a cerebral arterio vasoconstriction as it was evidenced by arteriographic images.
