Improvement of Cerebral Blood Flow in Acute Ischemia of the Brain

Part of the Advances in Neurosurgery book series (NEURO, volume 15)


The most appropriate therapy for acute cerebral ischemia is still a matter of debate. Attempts at vasodilation by hypercapnia (14a), pharmacological vasodilatation (16), and barbiturate protection (17) have not gained general acceptance:
  • Hypercapnia and administration of cerebral vasodilators may cause steal effects, so decreasing flow in the tissue of concern. Hyperventilation with consecutive vasoconstriction may cause an increase of flow in the ischemic tissue if vasoparalysis has taken place. However, in the neighborhood with reacting vessels, blood flow may be at a critical level which during hypocapnia leads to further flow depression and provocation of true ischemia.
