Airtraq, LMA CTrach and Macintosh Laryngoscopes in Tracheal Intubation Training: A Randomized Comparative Manikin...

Area of Science:

• Medical Education
• Anesthesiology
• Airway Management

Background:

• Simulation-based training is crucial for medical students before patient contact.
• Limited comparative studies exist on novice tracheal intubation using various devices.

Purpose of the Study:

• To compare the efficacy and ease of use of Airtraq, LMA CTrach, and Macintosh laryngoscopes for novice medical students.
• To evaluate intubation success rates, time, dental trauma, and learning difficulty.

Main Methods:

• 123 medical students with no prior intubation experience participated.
• Each student performed five tracheal intubations with each of the three devices on a manikin.
• Primary outcomes: first-attempt success rate and intubation time. Secondary outcomes: dental trauma, perceived difficulty, and optimization maneuvers.

Main Results:

• LMA CTrach required more attempts and had the longest intubation time.
• Airtraq was perceived as easiest to use and learn, with significantly less dental trauma.
• Macintosh laryngoscope was deemed most difficult to learn and required more head extension maneuvers.

Conclusions:

• Airtraq offers advantages for novice users, including shorter intubation times, reduced dental trauma, and easier learning.
• The findings support Airtraq as a potentially beneficial tool for initial airway management training.
