1P1-G05 Study of evaluation of surgical assistant systems : Objective evaluation of surgeon's stress using saliva and acceleration plethysmogram

Abstract

We propose a method for using surgeon's biological information to evaluate the surgeon's stress in his/her using a surgical assistant system. We focused on saliva and acceleration plethysmogram as the surgeon's biological information. The stress was measured by analyzing cortisol, alpha-amylase, and total protein in saliva, and we analyzed the acceleration plethysmogram variability as the indexes of autonomic nervous activity, those were coefficient of variance of the a-a interval and low-frequency band [0.02-0.15Hz] power spectrum (LF), high-frequency band[0.15-0.5Hz] power spectrum (HF), the ratio of LF to HF (LF/HF). To validate the effectiveness of the proposed method, we conducted a laparoscopic cholecystectomy simulation. In conclusion, we confirmed our method had an ability to objectively evaluate the surgeon's stress during surgery.
