Deep hypothermic circulatory arrest.
Effective cerebral protection remains the principle concern during aortic arch surgery. Hypothermic circulatory arrest (HCA) is entrenched as the primary neuroprotection mechanism since the 70s, as it slows injury-inducing pathways by limiting cerebral metabolism. However, increases in HCA duration has been associated with poorer neurological outcomes, necessitating the adjunctive use of antegr...
متن کاملDeep hypothermic circulatory arrest: I. Effects of cooling on electroencephalogram and evoked potentials.
BACKGROUND Deep hypothermia is an important cerebral protectant and is critical in procedures requiring circulatory arrest. The purpose of this study was to determine the factors that influence the neurophysiologic changes during cooling before circulatory arrest, in particular the occurrence of electrocerebral silence. METHODS In 109 patients undergoing hypothermic circulatory arrest with ne...

surgery. Microembolization of atherosclerotic debris, fat, and air was probably the cause. It followed that if cerebral blood flow was increased to excessive, " luxuriant " levels by adding carbon dioxide, then injury would be increased. Randomized trials of neuropsycho-metric outcome have confirmed just this. Three of four trials demonstrated an improved cognitive outcome in adults undergoing ...

متن کاملNeurologic Injury Following Hypothermic Circulatory Arrest
Cardiothoracic surgeons are faced with the challenge of protecting the brain during the sensitive time of interruption of normal cerebral blood flow. The brain is an exceptionally complex organ with a functional anatomy that is difficult both to understand and assess. Experimental and clinical studies have shown that the mechanism of neural injury is multifactorial. As such, discussions regardi...
