Stress
Conditions
Brief summary
Intraoperative stress among the surgical team can be a threat to patient safety and good teamwork. During surgery, surgeons often work under stressful conditions. Reducing intraoperative stress for surgeons could benefit surgeons and subsequently patients. Based on the hypothesis that an intraoperative pause including a sugar-containing drink would decrease surgeon's stress levels, the aim of this study is to compare stress levels, in relation to intraoperative stress and how this is affected by a pause including a sugar-containing drink in simulated operations.
Detailed description
A randomized controlled cross-over trial was conducted in a simulator environment. Primary endpoint was intra-individual change in salivary cortisol between simulations with or without a pause including a sugar containing drink. Secondary endpoints were change in heart rate, change in self-perceived stress measured by the State Trait Anxiety Inventory (STAI), and experience of the intraoperative pause.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Salivary cortisol | 10 minutes | Intra-individual change in salivary cortisol between simulations with or without a pause including a sugar containing drink. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Heart rate | 3 hours | Change in heart rate during surgery |
| self-perceived stress | 10 minutes | measured by the State Trait Anxiety Inventory (STAI) Each STAI item is given a weighted score of 1 to 4. A rating of 4 indicates the presence of a high level of anxiety for ten S-Anxiety items and eleven T-Anxiety items. A high rating indicates the absence of anxiety for the remaining ten S-Anxiety items and nine T-Anxiety items. |
| Experience of the intraoperative pause. | 10 minutes | Questionnaire with self-experience questions - no scale |
