Objective:To investigate the experience of moderate hypothermia(28℃) using in Stanford A aortic dissection.Methods:A retrospective analysis of 100 patients with Stanford A aortic dissection from January 2012 to March 2014, including 50 cases with deep(25℃) hypothermic circulatory surgery and 50 moderate(28℃) hypothermic circulatory surgery. The operation was performed with ascending aortic replacement, inclusiong aortic arch angioplasty, and stent implantation with descending aorta stent. The difference between the 2 groups during and after the operation was compared.Results:2 cases died in the hypothermia group, and 3 cases died in the deep hypothermia group. There were significant differences( P<0.05) between the middle and low temperature groups in the cooling time, the time of stopping circulation, the time of rewarming, the time of cardiopulmonary bypass, the time of operation, the time of operation, the time of conscious, the time of mechanical ventilation and the first day after the operation( P<0.05), but there was no significant difference between the creatinine and the bilirubin( P>0.05). Conclusion:Under the condition of sufficient cerebral perfusion and spinal cord protection, moderate hypothermia is safe, and it can reduce the operation time and postoperative complications. It has certain clinical significance.
