Conditions
Summary
Brain injury is a serious problem after cardiac surgery. Brain injury can become evident in the form of stroke and cognitive dysfunction after surgery. The current neuromonitoring technique used is unable to monitor the region of the brain that is most susceptible to injury. This study aims to use a novel, non-invasive brain monitoring technique known as multichannel functional near infrared spectroscopy to assess brain oxygenation at multiple brain regions simultaneously during cardiac surgery. This research enables the investigators to understand the differences between regional brain oxygenation during cardiac surgery and to assess the feasibility and effectiveness of multichannel functional near infrared spectroscopy to be used as a future brain monitoring technique to detect brain injury in cardiac surgery.
Eligibility
Inclusion Criteria1
- Adult cardiac surgery patients who are scheduled to have elective cardiac operations.
Exclusion Criteria4
- Under 18 years of age
- have skin lesions or other conditions that preclude the application of fNIRS to the head
- lack of written consent
- emergency surgery

Interventions
Patients who will be enrolled in this study will be monitored during cardiac surgery using multichannel fNIRS monitoring. This consists of wearing the NIRS cap that will be positioned on the patient's head according to international operational guidelines and will be secured to the temporal region of the patient's forehead. The NIRS cap is entirely non-invasive and does not pose any additional risk to the patient. Monitoring will be commenced prior to the induction of anesthesia. Subsequent surgical and medical care will not be affected.
