Ergotamine and cerebral blood flow.
We measured the cerebral blood flow (CBF) of 16 patients by the xenon-133 intracarotid method before and after the intramuscular injection of ergotamine tartrate. The regional and hemispheric CBF was unaltered, even in 3 migraneurs in who ergotamine relieved the headache. Ergotamine tartrate in therapeutic doses has no effect on the cerebral circulation.
متن کاملThe effect of ergotamine and dihydroergotamine on cerebral blood flow in man.
The effects of ergotamine and dihydroergotamine on cerebral blood flow was investigated 4 hours after i.v. injection as these drugs might be of importance for migraine treatment. Eight normal male volunteers (not suffering from migraine) received 0.5 mg ergotamine and 1 mg dihydroergotamine i.v. Cerebral blood flow was measured by the xenon-133 inhalation method and single-photon-emission compu...
متن کاملResponses of surface arteries and blood flow of ischemic and nonischemic cerebral cortex to aminophylline, ergotamine tartrate, and acetazolamide.
Responses of Surface Arteries and Blood Flow of Ischemic and Nonischemic Cerebral Cortex to Aminophylline, Ergotamine Tartrate, and Acetazolamide • In cats in which one middle cerebral artery was occluded, cortical blood flow (CBF) was measured and the superficial cortical microvasculature was observed bilaterally before and after the intravenous injection of a vasoactive drug. Aminophylline pr...
متن کاملWhole blood viscosity and cerebral blood flow.
BLOOD has anomalous rheological properties, particularly in certain disease states. It may therefore be necessary to consider these properties when attempting to assess and perhaps to improve the state of a patient's cerebral circulation. So what evidence is there that cerebral blood flow (CBF) is affected by viscosity? Before attempting to answer this question, one should be aware of what infl...
متن کاملHyperventilation and cerebral blood flow.
Hyperventilation and Cerebral Blood Flow • Hypocapnic-hyperventilation has a profound, but probably temporary, effect on CBF, producing approximately a 2% decline in CBF for each 1 torr decline in Pcov Th' effect appears to be mediated through changes in perivascular pH of the cerebral resistance vessels acting directly on the vessel wall. At low PC0;( the vasoconstrictor effect of short-term h...
