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.

Supraglottic airway devices constitute a fundamental component of modern airway management, with laryngeal mask airway (LMA) devices being widely implemented across various clinical anesthesia settings. The advent of video-assisted LMA systems has enabled real-time visual confirmation of device insertion and positioning, thereby enhancing procedural accuracy. Beyond their potential to improve patient safety outcomes, these advanced systems provide a pedagogical advantage by facilitating visual feedback during training, thus supporting the optimization of skill acquisition and educational effectiveness in airway management.

The primary aim of this study is to evaluate the learning curve of anesthesia residents during the placement of video-assisted laryngeal mask airway (video LMA) devices and to objectively assess our routinely implemented training protocol by systematically recording the process. Video-assisted airway devices, particularly video LMA systems, offer several advantages over conventional blind techniques. These advantages include higher success rates of insertion, shorter placement times, direct visual confirmation of proper positioning, and a reduction in airway-related complications. Today, many experts acknowledge that video-assisted techniques represent a new standard in supraglottic airway management with respect to both patient safety and educational utility.

Successful execution of video LMA placement requires the acquisition of three core and interrelated technical skills: obtaining an adequate view during insertion, correctly interpreting the visual information to assess device position, and performing precise manipulation through hand-eye coordination. These competencies are especially crucial for anesthesia residents undergoing training and must be effectively acquired during their educational development.

The use of LMA is common in routine elective surgeries. Video-assisted LMA systems are particularly beneficial in educational settings, as they provide real-time visual feedback for the operator and facilitate instructor-led guidance. Before initiating video LMA applications, residents in our institution undergo structured theoretical and practical training, followed by supervised clinical practice under the guidance of experienced anesthesiologists and academic staff. Through this study, we aim to analyze the learning curves of residents and objectively evaluate the effectiveness of the educational approach.

This study aims to evaluate the learning curves of residents in video laryngeal mask airway (LMA) placement and to objectively assess the effectiveness of the training program. This prospective observational study will be conducted with the participation of anesthesiology and reanimation residents at a university hospital. First- and second-year anesthesia residents with no prior experience in video LMA insertion will be included in the study.

Each participant will perform a predetermined number of video LMA insertions (≥10 cases) in adult patients undergoing elective surgery. For each attempt, success or failure, insertion time, quality of ventilation, and the occurrence of complications such as bleeding or gag reflex will be recorded. Success criteria will be based on standards defined in the literature, and all procedures will be carried out under the supervision of an experienced instructor.

Using the collected data, each participant's learning curve will be analyzed using the Cumulative Sum (CUSUM) method. This will allow for statistical assessment of the number of cases required for the learning process to reach a stable plateau.

Inclusion Criteria:

• Anesthesiology residents with less than two years of experience and no prior exposure to video laryngeal mask airway (LMA) placement.

Exclusion Criteria:

• Having prior hands-on experience with video laryngeal mask airway (LMA) placement

Anesthesiology residents in training who practice the application of video laryngeal mask airway (video LMA).
