Cerebrovascular autoregulation after rewarming from hypothermia in a neonatal swine model of asphyxic brain injury.
After hypoxic brain injury, maintaining blood pressure within the limits of cerebral blood flow autoregulation is critical to preventing secondary brain injury. Little is known about the effects of prolonged hypothermia or rewarming on autoregulation after cardiac arrest. We hypothesized that rewarming would shift the lower limit of autoregulation (LLA), that this shift would be detected by ind...
متن کاملEffects of glyceryl trinitrate on cerebrovascular autoregulation.
their interest in our article. First, we would like to apologize for mis-attributing the statement to the authors. The correct reference in our article was to 11 not 1 and it is not a direct quotation. We believe our survey provides sufficient evidence to raise concerns over the use of transtracheal ventilation using a high pressure source without control of airway pressure, but a survey lackin...
متن کاملCerebrovascular reactivity and dynamic autoregulation in tetraplegia.
Humans with spinal cord injury have impaired cardiovascular function proportional to the level and completeness of the lesion. The effect on cerebrovascular function is unclear, especially for high-level lesions. The purpose of this study was to evaluate the integrity of dynamic cerebral autoregulation (CA) and the cerebrovascular reactivity in chronic tetraplegia (Tetra). After baseline, stead...
متن کاملLoss of cerebrovascular autoregulation in experimental meningitis in rabbits.
The present study was designed to determine whether cerebrovascular autoregulation is intact in experimental meningitis and to examine the relationship between fluctuations in cerebral blood flow (CBF) and increased intracranial pressure (ICP). Measurements of CBF were determined by the radionuclide microsphere technique in rabbits with experimental Streptococcus pneumoniae meningitis with simu...
متن کاملRacemic ketamine does not abolish cerebrovascular autoregulation in the pig.
BACKGROUND Little is known about the influence of racemic ketamine on autoregulation of cerebral blood flow (CBF), and available reports regarding its influence on cerebral hemodynamics are contradictory. This study was designed to evaluate cerebrovascular responses to changes in the mean arterial pressure (MAP) during ketamine anesthesia. METHODS In eight normoventilated pigs anesthesia was ...
