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.

Objective To summarize and evaluate the clinical effect of extraco-rporeal membrane oxygenation(ECMO) support for critically ill patients after heart surgery,and to explore the factors that influenced the prognosis of ECMO.Methods The clinical data of 67 patients undergoing ECMO admitted to the Second Hospital of Jilin University from August 2013 to July 2017 were retrospectively analyzed.The patient's age ranged from 22 months to 78 years,including 3 infants aged 22,24,30 months and 64 adults ranged from 32 to 78 years,the mean age was(56.52 ± 10.99) years.Results The average ECMO support time was (235.79 ± 123.87) h,the mean mechanical ventilation time was (166.11 ± 148.31) h.49 patients weaned off successfully from ECMO,38 of them were discharged and 11 died within 28 days.18 patients gaved up treatment.42 patients suffered the complications.Conclusion VA-ECMO is a significant supportive method for preoperative intensive care in patients undergoing cardiovascular surgery.The keys to optimal results are grasping the indications of ECMO,earlier stopping mechanical ventilation,cluster curing(which involves reasonable anticoagulation,protection of organ function,prevention of hemorrhage,infection and limb distal ischemia).
