Clinical Trial Summary

This study aims to determine whether a new learning-curve-based simulation training modality could contribute to a noninferiority regarding bronchoscopic-guided intubation time in patients compared with the reference fixed-training-time simulation training modality, albeit with less training time.

Description:

Questions remain concerning the optimal duration of simulator training for flexible optical bronchoscopic (FOB) intubation. The investigators' previous study demonstrated that an exponential curve could fit the learning curve of FOB intubation training on a high-fidelity simulator after logarithmical transformation of the procedure time. In brief, trainees could achieve a plateau of the learning curve after several procedures, i.e., further training might provide only negligible progress. According to the investigators' preliminary study, the training time for the majority might be less than one hour which is the dominant duration of simulator training in previous studies. By generating a learning curve from the initial several procedures on a simulator, it is possible to predict when a trainee could grow saturated individually. It is hypothesized that this new learning-curve-based training modality could contribute to non-inferior FOB intubation time in patients compared with the reference fixed-training-time (1 hour) training modality, albeit with less training time. The noninferiority margin is defined according to the reported FOB intubation time and the training effect in previous studies. Moreover, it is plausible that this new training modality might even present a higher success rate and better performance of FOB intubation, considering each trainee following the new training has to achieve the individual goal that precludes an outlier from failing to have enough training that might occur in reference fixed-training-time training.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	time to complete FOB intubation	It is a noninferiority outcome. After training, one FOB intubation will be performed within one week. Patients scheduled for elective surgery which requires tracheal intubation will be included. Those with an anticipated or known difficult airway or American Society of Anesthesiology (ASA) Physical Status Classification equaling or exceeding III will be excluded. General anesthesia is performed by the attending anesthetists who does not involve in this study. Patients are mask ventilated for 2min after induction. Assistance with jaw thrust is provided during intubation. Criteria for termination of intubation are SpO 2 of 90% or less, airway tissue trauma during the intubation attempt, attempt time exceeding 4min, or the anesthetist in the charge being unwilling to continue.	Just after the completion of the intubation, in one minute
Secondary	duration of the training	The total duration of the simulation training on a high-fidelity simulator	From the training initiating to its ending, a sum will be calculated in 24 hours after the training
Secondary	total number of procedures on the simulators	The total number of procedures performing FOB on a high-fidelity simulator	From the training initiating to its ending, a sum will be calculated in 24 hours after the training
Secondary	success rate of intubation	Successful intubation in patients	Just after the completion of the intubation, in one minute
Secondary	performance of FOB intubation on simulators	The last 3 intubations on simulators will be assessed. The simulator assesses the performance based on the validated five-point global rating scale (GRS) of fiberoptic bronchoscope manipulation, which is standardized to a 100-scale score (0=worst, 100=best) automatically by the simulators.	After the training, the scores will be acquired from the data storage of the simulators in 24 hours
Secondary	performance of FOB intubation in patients	The intubation will be recorded and sent to an assessor, who will assess the performance using the five-point global rating scale (GRS, 8 items, 5 points each, up to a total of 40 points, 0=worst, 40=best) of fiberoptic bronchoscope manipulation in one week. To unify the results, the GRS will be standardized to a 100-scale score (0=worst, 100=best) in the analysis.	One week
