    Abstract:

    We evaluated cerebral vasomotor reactivity to acetazolamide in seven consecutive patients with intracerebral hemorrhage (ICH) with transcranial Doppler to evaluate autoregulation of cerebral blood flow in acute ICH. Two patients had prominent loss of vasoreactivity to acetazolamide stimulation. This suggests that autoregulation may be impaired in some patients with acute ICH. Further studies are required to determine the clinical implications of loss of autoregulation in acute phase of ICH.

    Autoregulation of Blood Flow

    9.0K
    Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
    Chemical Signaling in Autoregulation
    Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation....
