Key result
Less surgical experience, prolonged operation time, and excessive intraoperative blood loss were associated with higher intraoperative stress across 265 orthopedic surgery records.
Why the study?
It was unclear whether real-time intraoperative stress of orthopedic surgeons can be recognized and which factors affect it using EEG and HRV.

What factors affect the intraoperative stress of orthopedic surgeons as measured by EEG and HRV?
Less experienced orthopedic surgeons experience higher mental stress during surgery, and factors like prolonged operation time and excessive blood loss contribute to increased stress.
Kwon et al. (2021) conducted an observational in Intraoperative stress (n=265). Intraoperative factors (surgical experience, operation time, blood loss) vs. Senior surgeons / resting state was evaluated on Intraoperative stress parameters (EEG waves and HRV). Less surgical experience, prolonged operation time, and excessive intraoperative blood loss were associated with higher intraoperative stress across 265 orthopedic surgery records.
