Mechanism of cerebral blood flow augmentation by hemodilution in rabbits.
BACKGROUND AND PURPOSE Hemodilution is known to increase cerebral blood flow, but it is not known whether the increase in flow is a direct result of a decrease in viscosity or whether it may be due to compensatory vasodilatation in response to the decrease in oxygen carrying capacity that results from hemodilution. This study is designed to investigate this question. METHODS Changes in region...
متن کاملHemodilution increases cerebral blood flow in acute ischemic stroke.
We measured cerebral blood flow in 10 consecutive, but selected, patients with acute ischemic stroke (less than 48 hours after onset) before and after hemodilution. Cerebral blood flow was measured by xenon-133 inhalation and emission tomography, and only patients with focal hypoperfusion in clinically relevant areas were included. Hemodilution was done according to the hematocrit level: for a ...
متن کاملExperimental augmentation of regional cerebral blood flow by microvascular anastomosis.
Intracranial surgical procedures for cerebrovascular occlusive disease have become feasible with the development of microvascular surgical techniques. This study assessed the ability of microanastomosis of the superficial temporal cortical artery to augment cerebral blood flow after clip occlusion of the middle cerebral artery in the dog. A variable degree of flow depression and consistent disr...
متن کاملEffect of hemodilution on regional cerebral blood flow.
Regional cerebral blood flow decreases during chronic hyperglycemia, a condition frequently associated with elevated hematocrit. To test the hypothesis that an elevated hematocrit is responsible for the reduced regional cerebral blood flow during chronic hyperglycemia, I used isovolemic hemodilution to normalize the hematocrit in seven normoglycemic and seven streptozotocin-treated (hyperglycem...
متن کاملChanges in Cerebral Blood Flow and Brain Tissue Oxygen Tension during Normovolemic Hemodilution in Cryogenic Brain Injury of Rabbits
Fluid replacement after hemorrhage usually results in hemodilution. Hemodilution leads to increased cerebral blood flow, which is known to be beneficial to the outcome of ischemic brain damage. However, the effect of hemodilution may be different in patients with head injuries and increased intracranial pressure (ICP). The aim of this study is to evaluate the effects of normovolemic hemodilutio...
