TLDR
Wide, routine use of NIRS as a standard-of-care monitor cannot be recommended at present, but a novel application of processed NirS information for monitoring cerebral autoregulation and tissue oxygenation is promising.About:

Cerebral Autoregulation-oriented Therapy at the Bedside: A Comprehensive Review
Lucia Rivera-Lara,Andres Zorrilla-Vaca,Romergryko G. Geocadin,Ryan Healy,Wendy C. Ziai,Marek A. Mirski +5 more
TL;DR: The evidence indicates that monitoring of continuous cerebral autoregulation at the bedside is feasible and has the potential to be used to direct blood pressure management in acutely ill patients.
Journal ArticleDOI
Near-Infrared Spectroscopy in Adult Cardiac Surgery Patients: A Systematic Review and Meta-Analysis
Matthew J Chan,Tricia Chung,Neil J Glassford,Rinaldo Bellomo,Rinaldo Bellomo,Rinaldo Bellomo +5 more
TL;DR: It is established that reference values for baseline NIRS-derived SctO2 in cardiac surgery patients are varied and interventions that modulate SCTO2 are identified, which opens the door to standardized research and interventional studies in this field.
Journal ArticleDOI
A Multicenter Pilot Study Assessing Regional Cerebral Oxygen Desaturation Frequency During Cardiopulmonary Bypass and Responsiveness to an Intervention Algorithm
Balachundhar Subramanian,Charles B. Nyman,Maria D. Fritock,Rebecca Y. Klinger,Roman M. Sniecinski,Philip E. Roman,Julie L. Huffmyer,Michelle Parish,Gayane Yenokyan,Charles W. Hogue +9 more
TL;DR: This multicenter pilot study found that 50% to 75% of patients undergoing cardiac surgery experience one or more rScO2 desaturations during CPB, suggesting that appropriate alarming systems should be adopted to alert clinicians of such events.
Journal ArticleDOI
Cerebral oximetry and its role in adult cardiac, non-cardiac surgery and resuscitation from cardiac arrest
D. W. Green,Gudrun Kunst +1 more
TL;DR: A narrative review of monitors using near‐infra red spectroscopy to assess cerebral oxygenation levels non‐invasively in discrete areas of the brain aims to explore the rationale for using this technology but also the factors which have restricted its more widespread use.
Journal ArticleDOI
Cerebral Blood Flow Autoregulation in Sepsis for the Intensivist Why Its Monitoring May Be the Future of Individualized Care
TL;DR: Data reveal that individual BP goals determined from CBF autoregulation monitoring are more variable than previously expected, which suggests that the present consensus guidelines for BP management in sepsis may expose some patients to both cerebral hypoperfusion and cerebral hyperperfusion, potentially resulting in damage to brain parenchyma.

Journal ArticleDOI
Beneficial effect of carotid endarterectomy in symptomatic patients with high-grade carotid stenosis
Barnett Hjm.,D W Taylor,Richard Haynes,David L. Sackett,Sydney J. Peerless,Gary G. Ferguson,Allan J. Fox,R N Rankin,Vladimir Hachinski,Wiebers Do,Michael Eliasziw +10 more
TL;DR: Carotid endarterectomy is highly beneficial to patients with recent hemispheric and retinal transient ischemic attacks or nondisabling strokes and ipsilateral high-grade stenosis of the internal carotid artery.
Journal ArticleDOI
Noninvasive, infrared monitoring of cerebral and myocardial oxygen sufficiency and circulatory parameters
TL;DR: Observations by infrared transillumination in the exposed heart and in the brain in cephalo without surgical intervention show that oxygen sufficiency for cytochrome a,a3, function, changes in tissue blood volume, and the average hemoglobin-oxyhemoglobin equilibrium can be recorded effectively and in continuous fashion for research and clinical purposes.
Journal Article
Randomised trial of endarterectomy for recently symptomatic carotid stenosis: final results of the MRC European carotid surgery trial (ECST)
TL;DR: Carotid endarterectomy is indicated for most patients with a recent non-disabling carotid-territory ischaemic event when the symptomatic stenosis is greater than about 80%, but age and sex should also be taken into account in decisions on whether to operate.
Journal ArticleDOI
A review of the optical properties of biological tissues
TL;DR: The known optical properties (absorption, scattering, total attenuation, effective attenuation and/or anisotropy coefficients) of various biological tissues at a variety of wavelengths are reviewed in this article.
Journal ArticleDOI
Analysis of pooled data from the randomised controlled trials of endarterectomy for symptomatic carotid stenosis.
Peter M. Rothwell,Michael Eliasziw,Sergei A. Gutnikov,Allan J. Fox,D W Taylor,Mayberg,Charles Warlow,H. J. M. Barnett +7 more
TL;DR: Re-analysis of the trials with the same measurements and definitions yielded highly consistent results, indicating that surgery is of some benefit for patients with 50-69% symptomatic stenosis, and highly beneficial for those with 70% symptome stenosis or greater but without near-occlusion.
