Japanese randomized control Study of warm Total Arch Replacement

INTERVENTION: Group of 28 deg C : Temperature at bladder should be 28 plus minus 2 deg C, and the perfusion pressure of SCP should be over 50mmHg. Group of 20 deg C : Temperature at bladder should be 20 plus minus 2 deg C, and the perfusion pressure of SCP should be between 30 and 50mmHg. CONDITION: Patients undergoing total arch replacement without any additional cardiac procedures. PRIMARY OUTCOME: The primary parameter for the evaluation of the study is the total volume of transfusion. SECONDARY OUTCOME: The other parameters for the evaluation of the study are operative death, neurological complications, cardiac complications, respiratory complications, renal complications, amount of bleeding, and infectious complications. INCLUSION CRITERIA: Patients undergoing total arch replacement without any additional cardiac procedures. All operative procedures can be possible through median sternotomy.
