Study of the cerebral blood flow in patients with brain lesions under anesthesia

The influence of thiopental (Pentothal) on cerebral blood flow was studied by means of ten scintillationcounters in man on occasion of a carotid angiography. The patients received a basic anesthesia with 30% oxygen, 70% nitrous oxide and pancuronium bromide. When the anesthesia was stabilised, thiopental was given (4 mg/kg). The influence of barbiturates on autoregulation is discussed.
