Physiological Differences Between Emergency Medicine Residents and Novices During Cricothyrotomy: Evidence from Brain, Eye, and Heart Rate Measurements
SessionHC12: Biometric Applications
DescriptionNon-invasive physiological measurements have been used to distinguish levels of surgical expertise. However, existing research has primarily concentrated on commonly performed procedures, particularly laparoscopic surgery. This study focused on cricothyrotomy (CCT), a lifesaving emergency airway procedure. Since it is rare, it poses unique challenges for training and maintaining expertise, leading to a reported success rate of only 66% in the US military.
Twelve emergency medicine residents and eighteen novices (university students without operative experience) each performed three repetitions of the CCT procedure on a high-fidelity manikin. Multimodal physiological signals, including electroencephalography (EEG), heart rate variability (HRV), and pupil diameter (PD), were recorded. Performance was evaluated using a traditional checklist. T-test was performed on each metric to evaluate group differences.
Emergency medicine residents exhibited significantly higher frontal alpha power than novices, indicating more efficient cognitive processing among residents. They also showed a significantly larger increase in pupil diameter, suggesting a higher cognitive workload. This seemingly contradictory phenomenon was supported by residents' significantly higher performance scores and stronger activation in the left prefrontal lobe, suggesting their greater engagement. No significant difference was observed in HRV metrics. These results demonstrate the potential of physiological measurements to optimize CCT expertise assessment and surgical training.
