Brief Summary:
By comparing the clinical outcome of patients underwent different hypothermic circulatory arrest (mild hypothermic versus moderate hypothermic) during aortic arch surgery, this study aims to determine the optimal hypothermic circulatory arrest strategy for aortic surgery.
Detailed Description:
Hypothermic circulatory arrest (HCA) is the cornerstone of aortic surgery. It provides a bloodless and still operative field. But the side effect of hypothermia also draws people's concern. With the development of surgical techniques and cardiopulmonary bypass (CPB) management, the temperature of HCA has been raised from deep hypothermia (14.1-20 degree) to moderate hypothermia (20.1-28 degree), and it has been a primary choice for many surgeons around the world. Some of surgeons still tried to push the limit and started using mild hypothermia (28.1-34 degree), and satisfactory outcome was obtained. However, the optimal temperature of HCA has not yet been determined.
In this randomized controlled study, 80 informed and consenting patients who are scheduled for total arch replacement with concomitant proximal aortic reconstruction will be randomized to mild (28.1-34 degree) or moderate (20.1-28 degree) hypothermia during circulatory arrest. Clinical outcomes of both groups will be analyzed to determine the optimal temperature for HCA.
