Using a new brain monitoring technique during heart surgery
Evaluation of Cerebral Oxygenation Using Functional Near Infrared Spectroscopy in Adult Surgery
This study is testing a new way to check brain oxygen levels during heart surgery to see if it can help prevent serious complications like strokes.

What this trial studies
This study investigates the use of multichannel functional near infrared spectroscopy (fNIRS) to monitor brain oxygenation in patients undergoing cardiac surgery. It aims to assess the feasibility and effectiveness of this non-invasive technique in detecting cerebral injury, which can lead to serious complications such as stroke and cognitive dysfunction. By monitoring multiple brain regions simultaneously, the study seeks to provide insights into regional brain oxygenation during surgery and improve patient outcomes. The research addresses a critical gap in current neuromonitoring practices, which often fail to adequately assess the brain areas most vulnerable to injury during cardiac procedures.
Who should consider this trial
Good fit: Ideal candidates for this study are adult patients scheduled for elective cardiac surgery.
Not a fit: Patients under 18 years of age, those requiring emergency surgery, or individuals with skin conditions that prevent fNIRS application will not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to better monitoring and prevention of brain injuries during cardiac surgery, ultimately improving patient outcomes.
How similar studies have performed: While the use of fNIRS in surgical settings is emerging, this specific application in cardiac surgery is novel and has not been extensively tested in prior studies.
