Brief summary
The study evaluates differences in perceived and objective workload in anesthetists during intubation procedure with a direct (Mcintosh) or indirect (Glidescope) laryngoscope. Expert anesthetists will perform 3 intubations per device, while completing a secondary task, during which reaction times to an auditory stimulus will be recorded, and will complete a questionnaire (the NASA-Task Load Index) to evaluate their perceived workload at the end of each procedure.
Detailed description
Intubation and laryngoscopy are the most demanding procedure in anesthesiological routine clinical practice, associated with high workload. The measurement and management of workload is considered important in anesthesiology to prevent work-related stress and errors in performance. New devices, thanks to advances in technology, seem promising in reducing operators' workload and improving safety and success of intubation processes. Therefore, in this study, based on previous results, the hypothesis that the Glidescope videolaryngoscope reduces operators' perceived and and objective workload, as compared to the standard Mcintosh laryngoscope, will be tested. Expert anesthetists will perform 3 intubations per device in a randomized order, while completing a secondary task, during which reaction times (verbal responses) to an auditory stimulus (a clacson) will be recorded, and operators will complete a questionnaire (the NASA-Task Load Index) to evaluate their perceived workload at the end of each procedure.
Interventions
DEVICEGlidescope intubation
Anesthetists will perform intubation in patients undergoing elective neurosurgery with the Glidescope videolaryngoscope, while completing a secondary auditory task. Response times to the secondary task will be recorded, and operators will complete the NASA Task Load Index questionnaire at the end of each procedure.
DEVICEMcintosh intubation
Anesthetists will perform intubation in patients undergoing elective neurosurgery with the Mcintosh laryngoscope, while completing a secondary auditory task. Response times to the secondary task will be recorded, and operators will complete the NASA Task Load Index questionnaire at the end of each procedure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Perceived workload | Immediately after the procedure/intervention | Results from the self-reported NASA Task Load Index will be considered as measure of perceived subjective workload |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quantitative workload | During the laryngoscopy/intubation procedure | Reaction times to a secondary auditory task will be used as a measure of mental workload |
