Details and patient eligibility

About

VEEGix is a portable device developed by NeuroServo for simplifying electroencephalograms at the bedside. It is an easy-to-use device that only requires the operator to place an adhesive strip of electrodes on the patient's forehead, connected to the device. The goal of this study is to determine EEG thresholds for the diagnostic of delirium.

Methods : This prospective observational study includes patients undergoing orthopedic or degestive surgery. Each subject will have an EEG reading before surgery and twice daily after surgery until discharge or up to 5 days. Patients will be monitored for post operative delirium using the 3D-Confusion Assessment Method. Delirium diagnostic will be confirmed by a geriatrician. EEG relative power reading will be compared between patient with and without a delirium diagnostic.
