TLDR
The ultrasound index for detecting gaseous microemboli (MEI) indicated the presence of suchmicroemboli in 22 of the 27 patients during insertion of the aortic cannula during cardiopulmonary bypass surgery, supporting the assumption that the MEI is providing quantitative information regarding the existence of gaseously emboli in the middle cerebral artery.About:

TL;DR: The major areas of change reflected in the update of the ACC/AHA Guidelines for Coronary Artery Bypass Graft Surgery are described in a format that can be read and understood as a stand-alone document.

Impaired Clearance of Emboli (Washout) Is an Important Link Between Hypoperfusion, Embolism, and Ischemic Stroke
TL;DR: It is posited that impaired washout is an important but neglected concept that intertwines hypoperfusion, embolization, and brain infarction.
Journal ArticleDOI
The impact of microemboli during cardiopulmonary bypass on neuropsychological functioning
TL;DR: It is suggested that neuropsychological deficits after routine cardiopulmonary bypass are related to the number of microemboli delivered during surgery, and the numbers of microEmboli may be reduced by including a 40‐&mgr;m filter on the arterial line.

TL;DR: TCD is an efficient tool to access blood velocities within the cerebral vessels, cerebral autoregulation, cerebrovascular reactivity to CO(2), and neurovascular coupling in both physiological states and in pathological conditions such as stroke and head trauma.

TL;DR: The transcranial pulsed Doppler ultrasound and spectral analysis was used for detection of blood velocities in the basal cerebral arteries to assess four patients who had occlusive extracranial carotid disease and indicated the major collateral source was from the vertebrobasilar system.

Ultrasonic identification of sources of gaseous microemboli during open heart surgery

TL;DR: An ultrasonic transducer was used to detect gaseous microemboli during open heart surgery and demonstrated that the two types of disposable bubble oxygenators and disc oxygenators tested delivered microbubbles in the arterial blood.

Reduced platelet activation and improved hemostasis after controlled cardiotomy suction during clinical membrane oxygenator perfusions
PW Boonstra,Gw Vanimhoff,L. Eysman,Gj Kootstra,Jnh Vanderheide,G. F. Karliczek,Crh Wildevuur +6 more
TL;DR: In this article, the authors developed an automatic controlled cardiotomy suction system by which the aspiration of air along with suction of blood was prevented, which significantly reduced platelet activation and postoperative blood loss.

Comparison of bubble and membrane oxygenators in short and long perfusions.
Richard E. Clark,Richard A. Beauchamp,Robert A. Magrath,John D. Brooks,Thomas B. Ferguson,Clarence S. Weldon +5 more
TL;DR: In anticipated long perfusions or where bleeding may be a problem, a membrane oxygenator appears more efficacious than bubble systems, and for perfusions of less than 2 hours, membrane oxygenators had no biochemical or hematologic advantage over the bubble devices used in this study.
