    [摘要] 目的 探讨Stanford A型主动脉夹层中低温停循环手术的安全温度范围。方法 收集2015年1月～2016年10月同济医院收治的Stanford A型主动脉夹层手术患者40例，随机分为低温度组(鼻咽温22～ 0.05)。两组间TND(短暂性神经系统障碍)和PND(永久性神经障碍)差异无统计学意义(P > 0.05)；低温组ICU天数较高温组显著延长(P 0.05)。 结论 鼻咽温24～26℃是Stanford A型主动脉夹层中低温停循环手术合适的安全温度。

    [Abstract] Objective To explore the safe temperature range of the moderate hypothermic circulatory arrest surgery in Stanford type A aortic dissection. Methods From January 2015 to October 2016， in Tongji Hospital， 40 Stanford type A aortic dissection patients were divided into two groups by random number table， low temperature group (nasopharyngeal temperature 22-<24℃) and high temperature group (nasopharyngeal temperature 24-26℃)， with 20 cases in each group， all patients were given surgery under moderate hypothermic circulatory arrest and Unilateral paraminic brain irrigation. The intraoperative and postoperative situation in the two groups was observed. Results The CPB time in the low temperature group was significantly more than that in the high temperature group (P < 0.01) ......
