About this trial

The purpose of this study is to determine if the position of the anesthesia machine affects the ability of anesthesiologists to manage a crisis situation and perform critical tasks. Participants will be asked to manage a simulated crisis situation using a manikin in the operating room. The anesthesia machine will be positioned either in an "optimal" or "awkward" manner for the anesthesiologist. The session will be video recorded and then analysed for various outcomes that reflect the anesthesiologist's performance. Participants will also perform a critical task, bag-valve-mask ventilation, on a manikin with the anesthesia machine in the optimal and awkward positions. The effectiveness of ventilation in each position will be compared. The results of this study may have implications for patient safety.

Trial outcomes

Primary outcomes

1

Crisis performance

A composite performance score defined as the mean of standardized MEPA checklist score and standardized time to scenario completion.

Time frame
Measured during the crisis scenario, average time is 5 minutes

Secondary outcomes

1

Time metrics

Time from change in vital signs to intervention

Time frame
Measured during the crisis scenario, average time is 5 minutes
2

Case management score

Performance of predefined key tasks in the treatment of the simulated crisis

Time frame
Measured during the crisis scenario, average time is 5 minutes
3

Ergonomic/motor metrics

1. Number of times the hand(s) cross the midline and touches the machine or equipment 2. Number of times the anesthesiologist makes an adjustment to optimize BVM ventilation attempts: 3. Total number of degrees the anesthesiologist's head turns during the scenario 4. Total distance the anesthesiologist's hand travels during the scenario

Time frame
Measured during the crisis scenario, average time is 5 minutes
4

Workload measurement metrics

National Aeronautics and Space Administration Task Load questionnaire

Time frame
Questionnaire is completed after the participation in the crisis scenario is completed. The questionnaire will take an average of 10 minutes to complete.
