| Outline of Final Research Achievements |
This study aimed to evaluate cerebral deterioration of sleep-deprived, fatigued residents using neuroimaging techniques.Six medical residents were instructed to draw blood from imitation vessels installed in the arm of a normal cooperator. They drew blood at similar times of day, before and after night duty. While they drew blood, the change in cerebral hemodynamics was measured using a wearable near-infrared spectroscopy (NIRS). Although the total sleep time and sleep efficiency did not show significant decreases, there was a significant increase in heart rate when participants drew blood after night duty. Cerebral hemodynamics represented as [oxy-Hb] and [deoxy-Hb] did not show significant differences in impairment between the pre- and post-night duty shifts; however, significant cerebral hemodynamics were significantly impaired while they drew blood after night duty. This result implies that the brains of sleep-deprived medical residents were impaired after night duty.
