The use of laryngeal mask airway or i-gel to manage airway may improve success rates, especially in difficult situations more than tracheal intubation.

This study compares the insertion success rate and insertion time among the proceal laryngeal mask airway, i-gel, and tracheal tube. Following a short lecture, airway novices try to insert proceal laryngeal mask airway, i-gel, and tracheal tube into manikin with difficult laryngoscopy scenarios.

Inclusion Criteria:

• medical student
• nurse
• no experience of insertion using tracheal tube, i-gel, and laryngeal mask airway

Exclusion Criteria:

• experience of insertion using tracheal tube, i-gel, and laryngeal mask airway
