The Application of Eye-Tracking Technology in Perioperative Management and Education

Every anesthesiologist will record data from three cases. Data collection will commence as the general anesthesia procedure begins when the patient moves onto the surgical table and will complete when the patient reaches the states of sedation and unconsciousness in preparation for the operation. This period, during which the anesthesiologist plays a leading role, typically lasts less than 10 minutes. No data will be recorded once the surgical operation begins.

The Tobii eye-tracker will generate a diverse dataset, encompassing eye trajectory, fixation (a gaze resting on a spot for more than 150 ms), saccades (rapid eye movements between two distinct points), and pupil size. This comprehensive dataset enables us to identify the "hotspots" where anesthesiologists focus their attention within different areas of the anesthesia machines.

Moreover, we will calculate the percentage of time anesthesiologists' eyes spend on team members. We will also quantify the duration of eye contact and communication content between the anesthesiologist and each team member.

Finally, we will examine the correlation between these behavioral measures (e.g., fixation on hotspots, percentage of time focused on team members, communication episodes) and the duration of the anesthesia procedure.
