Changing body temperature during aortic arch surgery

Cerebral protection during aortic arch surgery.

Reliability of different body temperature measurement sites during aortic surgery.

OBJECTIVE We retrospectively performed a comparative analysis of temperature measurement sites during surgical repair of the thoracic aorta. METHODS Between January 2004 and May 2006, 22 patients (mean age: 63 ± 12 years) underwent operations on the thoracic aorta with arterial cannulation of the aortic arch concavity and selective antegrade cerebral perfusion (ACP) during deep hypothermic ci...

Insufficient unilateral cerebral perfusion during emergent aortic arch surgery.

A rare case of insufficient right-sided unilateral cerebral perfusion during emergent aortic arch replacement in a patient with an acute aortic dissection is reported. On the basis of intraoperative monitoring using near-infrared spectroscopy, the insufficient perfusion of the contralateral hemisphere was detected and the bilateral perfusion was performed, which led to normalization of cerebral...

Body Temperature During Surgery and Anesthesia

The recognition of fulmin ant hyperthermia and accidental hypothermia during anesthesia and surgery has given a new impetus to clinical thermometry in the operating room. It is sugges ted that in order to recognize and avoid these conditions in the anesthetized patient, a routine of continuous monitoring of body temperature be added to our armamentarium fo r patient care. One of the problems th...

Cerbral Protection Strategies for Aortic Arch Surgery

Surgical therapy for aortic arch disease involves partial or complete replacement of the aortic arch with reimplantation of the great vessels while the cerebral blood flow is temporarily altered. Patients undergoing this mandatory period of circulatory arrest during arch replacement are at an increased risk for adverse neurologic outcomes, and strategies for cerebral protection must be implemen...
