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: It is concluded that cardiopulmonary bypass with a bubble oxygenator alone initiates significantly (p less than 0.0001) more C3a activation and leukocyte sequestration than when methylprednisolone sodium succinate (30 mg/kg) is given 20 minutes before the start of cardiopULmonary bypass or when a silicone membrane oxygenator is used.

Neurologic dysfunction following cardiac operation with low-flow, low-pressure cardiopulmonary bypass.

TL;DR: The results suggest that CPB pressure, per se, is not the major determinant of postoperative neurologic and neuropsychological dysfunction.
Journal ArticleDOI
Monitoring middle cerebral artery blood velocity during carotid endarterectomy
TL;DR: Backbleeding in the internal carotid artery before insertion of the shunt was associated with diminished flow in the ipsilateral middle cerebral artery of ten patients, oscillatory forward/reverse flow in three patients and cessation of flow inThe remaining six patients.

Brain hyperperfusion during cardiac operations. Cerebral blood flow measured in man by intra-arterial injection of xenon 133: evidence suggestive of intraoperative microembolism.
TL;DR: Measurements of CBF during ECC hold promise as a guide toward safer cardiac operations and a normal and significant correlation with temperature and plasma PCO2 support the reliability of the method.

Cerebral protection during open-heart surgery.
T Aberg,M Kihlgren +1 more
TL;DR: To reduce the incidence of cerebral damage after open-heart surgery measures were undertaken based on physiological principles and consideration of the possible injury caused by microemboli, and psychometric testing is a useful method for evaluating the quality of cardiopulmonary bypass as it allows a quantitative assessment of postoperative cerebral function.
