Cerebral Autoregulation in Subarachnoid Hemorrhage [PDF]

Frontiers in Neurology, 2021
Subarachnoid hemorrhage (SAH) is a devastating stroke subtype with a high rate of mortality and morbidity. The poor clinical outcome can be attributed to the biphasic course of the disease: even if the patient survives the initial bleeding emergency ...

Impaired Cerebral Autoregulation during Head Up Tilt in Patients with Severe Brain Injury. [PDF]

PLoS ONE, 2016
Early mobilization is of importance for improving long-term outcome for patients after severe acquired brain injury. A limiting factor for early mobilization by head-up tilt is orthostatic intolerance.

Cerebral autoregulation monitoring in neonates and infants after cardiac surgery with cardiopulmonary bypass - comparison of single ventricle and biventricular physiology [PDF]

Frontiers in Pediatrics
IntroductionCardiopulmonary bypass surgery can lead to impaired cerebral autoregulation with the risk for ischemia, hemorrhage and delirium. In particular, infants with single ventricle physiology have altered hemodynamics with persistent veno-arterial ...

Bioelectrical Impedance-Based Time-Domain Analysis for Cerebral Autoregulation Assessment [PDF]

Sensors
Cerebral autoregulation refers to the ability of cerebral vasculature to maintain stable blood flow by adjusting vascular resistance in response to changes in perfusion pressure.

Age-Related Alterations of Cerebral Autoregulation. [PDF]

Life (Basel)
Intact regulation of cerebral blood flow (CBF) is essential for preserving cognitive function and reducing the risk of cerebrovascular events, particularly in the aging population. Autoregulation of CBF is one of the fundamental mechanisms that ensure constant supply for brain tissue by maintaining relatively stable perfusion despite fluctuations in ...

Recent advances in cerebral oximetry. Assessment of cerebral autoregulation with near-infrared spectroscopy: myth or reality? [version 1; referees: 2 approved] [PDF]

F1000Research, 2017
In recent years, the feasibility of near-infrared spectroscopy to continuously assess cerebral autoregulation has gained increasing interest. By plotting cerebral oxygen saturation over blood pressure, clinicians can generate an index of autoregulation ...

Impaired Cerebral Autoregulation in Children. [PDF]

Pediatr Neurol
Managing acute brain injury involves protecting the brain from secondary injury by addressing the mismatch between metabolic demand and cerebral perfusion. Observational studies have associated impaired cerebral autoregulation, a physiological process governing the regulation of cerebral blood flow, with unfavorable neurological outcomes in both ...

The Effect of Impaired Cerebral Autoregulation on Postoperative Delirium in Neonates and Infants After Corrective Cardiac Surgery: A Study on Modifiable Risk Factors for Delirium [PDF]

Reviews in Cardiovascular Medicine
Background: The risk factors for developing postoperative pediatric delirium (PD) are multifactorial and include underlying conditions, cyanosis, surgery, intensive care stay, analgesia used for sedation, and withdrawal symptoms ...

Impact of impaired cerebral blood flow autoregulation on electroencephalogram signals in adults undergoing propofol anaesthesia: a pilot study

BJA Open, 2022
Background: Cerebral autoregulation actively maintains cerebral blood flow over a range of MAPs. During general anaesthesia, this mechanism may not compensate for reductions in MAP leading to brain hypoperfusion.

Perspective on Cerebral Autoregulation Monitoring in Neonatal Cardiac Surgery Requiring Cardiopulmonary Bypass

Frontiers in Neurology, 2021
The autoregulation of cerebral blood flow protects against brain injury from transient fluctuations in arterial blood pressure. Impaired autoregulation may contribute to hypoperfusion injury in neonates and infants.
