Effects of Hypothermia on Delayed Neurocognitive Recovery (DNR): an Observational Trial Among Patients Undergoing Cardiac-Surgery

Effects of Hypothermia on Delayed Neurocognitive Recovery: an Observational Trial Among Patients Undergoing Cardiac-Surgery

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.

Inclusion Criteria:

• Adults patients undergoing Cardiac - Surgery intervention with extracorporeal circulation

Exclusion Criteria:

• Neurological disease before surgery
• Sedation in Cardiac-Surgery Intensive Unit > 6 hours
• Cerebral regional Oxygen saturation <20% baseline during surgery
