Clinical Trial Summary

Post-operative cognitive dysfunction is a common disease in patient undergoing general anaesthesia, especially in older patients. No correlations have been yet studied between intraoperative hypothermia and incidence of Delayed Neurocognitive Recovery. Investigators are going to estimate the Relative Risk of Hypothermia and emergence of Post-operative cognitive dysfunction in cardiac-surgery patients.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of Delayed Neurocognitive Recovery in Cardiac-Surgery	Discover changes between pre-operative general cognition tests (Montreal Cognitive Assessment and Short Portable Mental Status Questionnaire) test score and post-operative Montreal Cognitive Assessment test score.	Patients will be subjected to Montreal Cognitive Assessment and Short Portable Mental Status Questionnaire test one day before surgery and 4-6 days after surgery
Primary	Incidence of Delayed Neurocognitive Recovery in Cardiac-Surgery	Discover changes between pre-operative Trail Making Test A and B score and post-operative Trail Making Test A and B score.	Patients will be subjected to Trail Making Test A and B one day before surgery and 4-6 days after surgery
Primary	Incidence of Delayed Neurocognitive Recovery in Cardiac-Surgery	Discover changes between pre-operative Digit Span Test score and post-operative Digit Span Test score.	Patients will be subjected to Digit Span Test one day before surgery and 4-6 days after surgery
Primary	Incidence of Delayed Neurocognitive Recovery in Cardiac-Surgery	Discover changes between pre-operative Frontal Assessment Battery test score and post-operative Frontal Assessment Battery test score and	Patients will be subjected to Frontal Assessment Battery test one day before surgery and 4-6 days after surgery
Secondary	Effects of hypothermia during Extracorporeal Circulation in Cardiac Surgery	Discover statistical significance difference in incidence of Post-Operative Cognitive Decline between patients undergoing normothermia and patients undergoing hypothermia during Extracorporeal Circulation in Cardiac Surgery	One day before surgery and 4-6 days after surgery patients will be subjected to cognitive test to diagnosticate Post-Operative Cognitive Decline
