Researchers assessed the stress levels of 66 surgeons and used the NASA Task Load Index and Stress Arousal Checklist and urine biopyrin levels to measure outcomes. Their findings suggest as the length of surgery and the amount of surgical blood loss increased, surgeons’ stress levels increased as well.
Further, nighttime surgery, which significantly decreased sleep time, contributed to an increase in urine biopyrin levels. Stress Arousal Checklist Arousal Scale scores also lowered significantly the morning after night surgery and the evening after the end of the following day shift.
