Brief Summary

Supraglottic airway devices hold a significant role in modern airway management, and laryngeal mask airway (LMA) devices are widely utilized in clinical anesthesia practice. Recently developed video-assisted LMA systems enable direct visual assessment of device placement and positioning. This technology not only has the potential to enhance patient safety but also offers an opportunity to optimize the learning process by providing visual feedback during training. Enhancing the technical proficiency of anesthesia residents in airway management is a fundamental component of their education. However, the contribution of next-generation devices such as video LMAs to the learning process and the characterization of their learning curve have been scarcely addressed in the literature. In this context, a quantitative evaluation of the acquisition process of video-assisted LMA insertion skills may provide valuable insights for both educational strategies and patient safety.

Conditions

Laryngeal Mask Airways; Airway Devices

Keywords

Third generation supraglottic airway devices; Cumulative Sum learning curves

Outcome Measures

Primary Outcomes (1)

• Success rate and learning curve in the acquisition of video LMA insertion skills

  Based on the collected data, the learning curve of each participant will be calculated using the CUSUM analysis method. This will allow a statistical evaluation of the number of cases after which the learning process stabilizes and reaches a plateau.

  From the first video LMA application attempt to the completion of the 10th attempt for each participant, within the data collection period of May 20, 2025, to August 20, 2025.
