Physical work performed by surgeons during orthopaedic operations.
Four surgeons participated in a study which aimed to demonstrate the physical work load during operations. Maximal oxygen uptake and maximum heart rate were determined by using the Douglas bag technique and recording the heart rate during the tests. By working at two submaximal work loads, heart rate was recorded and miximal oxygen uptake was determined indirectly. Using telemetry, heart rate was recorded during operation, and the mean oxygen uptake was determined. In 90 per cent of all operations the surgeons were working at a level of 20 to 30 per cent of their maximal aerobic capacity. There was an increase in body temperature and a decrease of body weight after all operations. In long lasting operations a decrease of grip force was noted.
