“…In general, beta blockers have had a greater effect on heart rate than on blood pressure. Foster et al 39 reported a mean decrease in heart rate of 3 1 % ( -37 beatshin) in 8 surgeons while working after a single dose of 40 mg oxprenolol. Light,27 using mental arithmetic, described inhibition of arousal of heart rate in 12 healthy students after 4 mg intravenous propranolol with a greater response in "high HR responders"; the effects of systolic blood pressure were more modest, but diastolic pres-sure increased significantly during mental arithmetic after intravenous propranolol.…”

Summary:Stress testing was carried out by two stressors, mental arithmetic and Sacks-Levy's test in randomized sequence, in 64 male patients with a mean age of 5 1 f 7 years in NYHA Classes I or II within 3 months after acute myocardial infarction. The stress profile was obtained after drug withdrawal by continuous recording of electrocardiogram, frontalelectromyogram, and peripheral skintemperature and conductance. Blood pressure was measured each minute by cuff. The patients were subdivided into4 groups of 16each and were studied inan identical fashionaftera48-h oral treatment with propranolol 120 mg daily, atenolol 100 mg daily, chlordesmethyldiazepam 2 mg daily, or placebo. During stress, signs of myocardial ischemia or pump failure were not observed; minor arrhythmias were recorded. Cardiovascular activation was observed with significant increments(p < O.OOl)inheartrate, systolicand diastolic blood pressures in all 4 groups for both stressors with a slightly greater effect of mental arithmetic; Sacks' test was more effective on the frontal electromyograph response. Following beta blockade the stress profile of heart rate was significantly lower and flattened. The stress profile of blood pressure was also lower, but the reduction in the increment during stress was not significant. No differences were observed in the effects of the two beta blockers; no significant changes were evident in the stress profile of the noncardiovascular psychophysiologic indexes. Stress profiles were not altered by the benzodiazepine. In conclusion beta-blocker agents seem to be more useful than anxiolytic drugs in preventing cardiovascular activation induced by mental stress in patients with recent myocardial infarction.

“…Studies conducted during the last three decades that focused on monitoring and analyzing surgeons' work had different findings and reached contradictory conclusions [6,7,9,11,12,15,16,22,23,30]. The studies were all stress-based and mostly analyzed cardiovascular parameters, such as heart rate and heart rate variability.…”

“…The studies were all stress-based and mostly analyzed cardiovascular parameters, such as heart rate and heart rate variability. In some of these studies, performing surgery was shown as ''exhausting for the body'' or ''increasing heart rate to more than 150/minutes'' [12,15]. In others, ''surgeons did not work physically remarkably hard nor demonstrated any obvious physiological signs of undue emotional stress'' [6].…”

“…Several studies did not specify the operative procedure during which the monitoring was performed [6,16,22,23], thus rendering the interpretation of emotional stress and especially physical demands impossible. Also, the number of participants-surgeons included in these studies was relatively small (two to 12; median, eight) [6,7,9,11,12,15,16,22,23,30], diminishing the power of the studies and introducing the possibility of selection bias.…”

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.
