Key result
Operating residents exhibited higher stress levels during cardiac surgery compared to experienced surgeons, indicated by lower RMSSD and a higher stress index.
Why the study?
The study aimed to use heart rate variability parameters to assess postulated increased stress levels in cardiac surgeons in training compared to experienced senior surgeons during the same surgical interventions.
Does performing cardiac surgery as a trainee resident increase physiological stress compared to assisting as an experienced senior surgeon?

Does performing cardiac surgery as a trainee resident increase physiological stress compared to assisting as an experienced senior surgeon?
Trainee cardiac surgery residents exhibit higher physiological stress levels and lower parasympathetic activity during surgical interventions compared to experienced senior surgeons.

May warrant monitoring trainee stress in cardiac ORs; cross-sectional data leave open whether experience reduces physiological burden.
BACKGROUND: This study analysed the psychological and psycho-emotional stress in cardiac surgery. Using heart rate variability (HRV) analysis, it is possible to record intraoperative objective stress responses in surgeons. The aim of the study was to assess with the help of HRV parameters the postulated increased stress levels of cardiac surgeons in training compared to experienced senior cardiothoracic surgeons in exactly the same work situation in order to make qualification-differentiated statements about physiological stress during surgical interventions. METHODS: = 15 each) for two operating residents and their assisting senior physicians were recorded. Time and frequency domain HRV parameters were analysed. RESULTS: The time-related parasympathetic-dominated HRV parameters RMSSD (19.5 ms vs. 28.1 ms), NN50 (297.67 vs. 693.40), and cardiac interval mean RR (692.8 ms vs. 737.3 ms) indicate a higher stress level in the operating residents compared to the experienced surgeons. The higher stress index (11.61 vs. 8.86) confirms this. CONCLUSION: Compared to experienced surgeons, operating residents showed lower parasympathetic activity and higher stress levels during cardiac surgery training procedures.

Awad et al. (2021) conducted an observational in Intraoperative stress. Operating as a cardiac surgery resident vs. Operating as an experienced senior cardiothoracic surgeon was evaluated on RMSSD (time-related parasympathetic-dominated HRV parameter). Operating residents exhibited higher stress levels during cardiac surgery compared to experienced surgeons, indicated by lower RMSSD and a higher stress index.
