Anesthesia Maintenance and Vigilance

Abstract

Limited research has focused on vigilance during the maintenance phase of anesthesia work. The goal of this study was to identify anesthesia maintenance tasks and to identify the transitions between these tasks within the perspective of the vigilance paradigm. In this study, three bariatric surgeries were recorded and analyzed using a task categorization structure. Across the surgeries the primary anesthesia provider spent 71% of their time doing patient or display monitoring tasks. Task frequency and transition visualizations were generated to identify trends in the task switching. Transitions between the task categories occurred approximately once every nine seconds for the primary anesthesia provider. Additionally, it appears that regardless of the task, there was a high frequency of task transitions to looking at the visual displays and then from the visual displays towards the patient. The results of this study emphasize the importance of vigilance for anesthesia display design.
