Cerebral Autoregulation in Sick Infants:Current Insights [PDF]

open access: yes, 2020
Cerebrovascular autoregulation is the ability to maintain stable cerebral blood flow within a range of cerebral perfusion pressures. When cerebral perfusion pressure is outside the limits of effective autoregulation, the brain is subjected to ...

Targeted temperature management in acute liver failure: A systematic review

open access: yesNursing in Critical Care, Volume 27, Issue 6, Page 784-795, November 2022., 2022
Abstract Background Targeted temperature management is the modern term for therapeutic hypothermia, where cooling is induced by intensive care clinicians to achieve body temperatures below 36°C. Its use in acute liver failure to improve refractory intracranial hypertension and patient outcomes is not supported by strong quality evidence.

Cerebrovascular Impedance as a Function of Cerebral Perfusion Pressure

open access: yesIEEE Open Journal of Engineering in Medicine and Biology, 2023
Goal: Cerebrovascular impedance is modulated by a vasoactive autoregulative mechanism in response to changes in cerebral perfusion pressure. Characterization of impedance and the limits of autoregulation are important biomarkers of cerebral health.

Cerebral autoregulation after aneurysmal subarachnoid haemorrhage. A preliminary study comparing dexmedetomidine to propofol and/or midazolam [PDF]

open access: yes, 2020
Background Cerebral autoregulation is often impaired after aneurysmal subarachnoid haemorrhage (aSAH). Dexmedetomidine is being increasingly used, but its effects on cerebral autoregulation in patients with aSAH have not been studied before ...

Impaired Cerebral Autoregulation After Subarachnoid Hemorrhage: A Quantitative Assessment Using a Mouse Model

open access: yesFrontiers in Physiology, 2021
Subarachnoid hemorrhage (SAH) is a common form of hemorrhagic stroke associated with high rates of mortality and severe disability. SAH patients often develop severe neurological deficits days after ictus, events attributed to a phenomenon referred to as

Cerebral autoregulation in Alzheimer's disease [PDF]

open access: yesJournal of Cerebral Blood Flow & Metabolism, 2011
Cerebral autoregulation aims to stabilize blood flow to the brain during variations in perfusion pressure, thus protecting the brain against the risks of low or high systemic blood pressure. This vital mechanism is severely impaired in the transgenic mouse model of Alzheimer's disease (AD) that abundantly produces amyloid-β peptide β1-42.

Changes in cerebral autoregulation and vasoreactivity after surgical aortic valve replacement: a prospective study

open access: yesExperimental Physiology, 2023
Surgical aortic valve replacement (SAVR) alters the natural course of severe aortic stenosis (AS). In this study, we aimed to determine the effects of the disease on dynamic cerebral autoregulation and vasoreactivity (VR) and to assess their changes ...

Venous sinus stenting improves cerebral autoregulation in a patient with venous sinus stenosis: a case report

open access: yesBMC Neurology, 2020
Background Venous sinus stenosis (VSS) is a type of cerebral venous vascular disease. Cerebral autoregulation is an indicator of cerebral arterial function. The cerebral circulatory system is composed of the venous system and arterial system.

Effects of positive end-expiratory pressure on cerebral hemodynamics in acute brain injury patients

open access: yesFrontiers in Physiology, 2023
Background: Cerebral autoregulation is the mechanism that allows to maintain the stability of cerebral blood flow despite changes in cerebral perfusion pressure.

Cerebrovascular reactivity and cerebral autoregulation are improved in the supine posture compared to upright in healthy men and women

open access: yesPLoS ONE, 2020
Cerebrovascular reactivity and cerebral autoregulation are two major mechanisms that regulate cerebral blood flow. Both mechanisms are typically assessed in either supine or seated postures, but the effects of body position and sex differences remain ...
