Key result
Performing total hip arthroplasty significantly increased surgeons' cardiovascular parameters, with the most demanding phase requiring 41.5% of their cardiovascular maximum, equivalent to moderate-intensity daily activities.

Performing total hip arthroplasty elicits a cardiovascular response in surgeons comparable to moderate-intensity daily activities.
THA elicits moderate cardiovascular strain in surgeons; hypothesis-generating for surgeon fitness or fatigue effects, with no practice change warranted.
The literature contains limited and contradictory information regarding the amount of physical effort and/or emotional stress needed to perform surgery. We therefore investigated cardiovascular response to psychophysical stress in orthopaedic surgeons while they were performing surgery. We monitored 29 male orthopaedic surgeons from four university centers while they performed total hip arthroplasties. Changes in their cardiovascular parameters were recorded by ambulatory monitoring methods. Exercise stress testing of each participant was used as a control state. We compared the cardiovascular response during surgery to energy requirements of everyday activities. Preoperative and postoperative testing showed lower values of cardiovascular parameters than during physically less difficult parts of the operation; physically more difficult phases of the operation additionally increased the values of parameters. We concluded performing total hip arthroplasty increases surgeons' cardiovascular parameters because of psychologic stress and physical effort. Excitement of the cardiovascular system during total hip arthroplasty appears similar to the excitement during moderate-intensity daily activities, such as walking the dog, leisurely bicycling, or climbing stairs.

Bergovec et al. (2008) conducted an observational in Psychophysical stress during total hip arthroplasty (n=29). Performing total hip arthroplasty vs. Postoperative rest was evaluated on Rate-pressure product (*1000) during the most physically demanding part of the operation (femoral endoprosthesis implantation) compared to postoperative rest (p=<0.001). Performing total hip arthroplasty significantly increased surgeons' cardiovascular parameters, with the most demanding phase requiring 41.5% of their cardiovascular maximum, equivalent to moderate-intensity daily activities.
