Compromised Cerebrovascular Regulation and Cerebral Oxygenation in Pulmonary Arterial Hypertension

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundFunctional cerebrovascular regulatory mechanisms are important for maintaining constant cerebral blood flow and oxygen supply in heathy individuals and are altered in heart failure. We aim to examine whether pulmonary arterial hypertension (PAH)

Effects of Acute Bleeding Followed by Hydroxyethyl Starch 130/0.4 or a Crystalloid on Propofol Concentrations, Cerebral Oxygenation, and Electroencephalographic and Haemodynamic Variables in Pigs

Veterinary Medicine International, 2014
Bleeding changes the haemodynamics, compromising organ perfusion. In this study, the effects of bleeding followed by replacement with hydroxyethyl starch 130/0.4 (HES) or lactated Ringer’s (LR) on cerebral oxygenation and electroencephalogram-derived ...

Brain oximetry is not a good monitor on reducing neurological complications after cardiac surgery

Universa Medicina, 2019
Background Cerebral deoxygenation is related to several adverse systemic consequences. We aimed to assess the effect of noninvasive monitoring of cerebral oxygenation on reducing neurological complications after cardiac surgery.

Preoperative assessment of cerebral blood flow as a predictor of cerebral desaturation during shoulder arthroscopy

Медицина неотложных состояний
Background. The beach-chair position during shoulder arthroscopy is associated with systemic and cerebral hemodynamic alterations that may contribute to cerebral hypoperfusion and intraoperative desaturation. However, the predictive value of preoperative

Multi-channel functional near-infrared spectroscopy for real-time monitoring during carotid artery stenting: a case series

Frontiers in Neuroscience
Functional near-infrared spectroscopy (fNIRS) offers a non-invasive method to monitor cerebral oxygenation and hemodynamic changes in real time. Transient hemodynamic instability during carotid artery stenting (CAS) may compromise blood–brain barrier ...
