Blind Intubation Through the Tulip Airway Versus Direct Laryngoscopy

This study is a randomized crossover mannequin-based simulation designed to compare two endotracheal intubation techniques performed by novice operators with limited or no prior intubation experience.

Participants will perform tracheal intubation using two different methods in a randomized order: (1) blind endotracheal intubation via the Tulip oropharyngeal airway, and (2) direct laryngoscopy. Each participant will serve as their own control in a crossover design, allowing direct comparison of the two techniques under standardized simulated airway conditions.

The primary objective is to compare the success rate of intubation between the two techniques. Secondary outcomes may include time to successful intubation, number of attempts, and ease of use, as assessed in a controlled simulation environment.

All procedures will be performed on airway mannequins in a simulation setting without involving human subjects or patient care. The study is intended to evaluate technical performance and feasibility in a standardized training environment, rather than clinical effectiveness in patients.

Inclusion criteria

• Voluntary participation in the study
• Anesthesia technician students with no prior airway management experience
• Age ≥ 18 years
• Willingness to participate in simulation-based intubation procedures

Exclusion criteria

• Prior advanced airway management experience (e.g., regular intubation practice in clinical settings)
• Refusal to participate or withdraw consent
• Inability to complete simulation procedures for any reason
