Brief Summary

This is a randomized crossover mannequin study comparing two airway management techniques in novice operators: blind endotracheal intubation via the Tulip oropharyngeal airway versus direct laryngoscopy. The study aims to evaluate and compare the success rate and performance characteristics of both methods under simulated conditions in order to assess their effectiveness in airway management training and practice.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Masking Details: No masking is used in this study. Both participants and investigators are aware of the intervention being performed, and outcome assessment is conducted in an open-label manner during a simulation-based setting.
• Purpose: BASIC SCIENCE
• Intervention Model: CROSSOVER
• Sponsor Type: OTHER GOV
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Principal Investigator

Model Details: This is a randomized crossover simulation study in which each participant performs endotracheal intubation using two different airway management techniques: blind intubation via the Tulip oropharyngeal airway and direct laryngoscopy. The order of interventions is randomized, and each participant serves as their own control. All procedures are conducted on airway mannequins in a controlled simulation environment, allowing direct comparison of the two techniques under standardized conditions.
