Type 2 diabetes is associated with an increased risk of endothelial dysfunction and microvascular complications with impaired autoregulation of tissue perfusion. Both microvascular disease and cardiovascular autonomic neuropathy may affect cerebral autoregulation. In the present study, we tested the hypothesis that, in the absence of cardiovascular autonomic neuropathy, cerebral autoregulation ...
The frequency-response of pressure autoregulation is not well delineated; therefore, the optimal frequency of arterial blood pressure (ABP) modulation for measuring autoregulation is unknown. We hypothesized that cerebrovascular autoregulation is band-limited and delineated by a cutoff frequency for which ABP variations induce cerebrovascular reactivity. Neonatal swine (n = 8) were anesthetized...
BACKGROUND Patient rewarming after hypothermic cardiopulmonary bypass (CPB) has been linked to brain injury after cardiac surgery. In this study, we evaluated whether cooling and then rewarming of body temperature during CPB in adult patients is associated with alterations in cerebral blood flow (CBF)-blood pressure autoregulation. METHODS One hundred twenty-seven adult patients undergoing CP...
Traumatic brain injury (TBI) occurs when a sudden trauma causes damage to the brain. TBI can result head suddenly and violently impacts an object or pierces skull enters tissue. Secondary injuries after traumatic lead impairments on cerebral oxygenation autoregulation. Considering that secondary often take place within first hours trauma, noninvasive monitoring might be helpful in providing ear...
