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), and there was no statistically significant difference in the aortic clamping time and the arrest time between the two groups (P > 0.05). There was no significant difference in TND and PND between the two groups (P > 0.05). The ICU time in the low temperature group was significantly more than that in the high temperature group (P < 0.05). There was no significant difference in the hospitalization time and inpatient mortality between the two groups (P > 0.05). Conclusion 24-26℃ is a more safe nasopharyngeal temperature range in Stanford type A aortic dissection during moderate hypothermic circulatory arrest.
