Comparison of Laryngeal Mask and I-gel to Laryngoscope by Novice Operators in Simulated Difficult Airway

Not Applicable

• Conditions: Airway Obstruction
• Interventions: Device: i-gel; Device: proceal laryngeal mask airway; Device: tracheal tube

• Registration Number: NCT02224027
• Lead Sponsor: Yeungnam University College of Medicine

Brief Summary

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

Detailed Description

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.
