Procedural Training in Acute Care: A Prospective Study of Learning Intubation Highlighting a Novel Method.

Area of Science:

• Anesthesiology
• Medical Devices
• Airway Management

Background:

• Endotracheal intubation (ETI) is a critical procedure in emergency medicine and anesthesia.
• Difficult airways present challenges, necessitating effective devices and techniques for rapid intubation.
• Novice and intermediate practitioners may struggle with complex airway scenarios.

Purpose of the Study:

• To compare the efficacy of a novel laryngoscope against standard devices for endotracheal intubation.
• To evaluate intubation times in simulated easy and difficult airway scenarios across different skill levels.
• To assess the impact of the Seldinger technique with a gum elastic bougie (GEB) on intubation speed.

Main Methods:

• Ninety-eight participants (novice, intermediate, expert) performed ETI on manikins simulating easy and difficult airways.
• Four devices were tested: novel laryngoscope, Macintosh blade alone, Macintosh with GEB, and GlideScope.
• Intubation time was measured from device insertion to lung inflation; bougie use involved the Seldinger technique.

Main Results:

• The novel laryngoscope with GEB showed faster intubation times (32.0s) compared to Macintosh with GEB (37.5s) in novice/intermediate groups on difficult airways (p < 0.05).
• Techniques using a bougie (Macintosh with GEB, Novel Laryngoscope with GEB) resulted in slower intubation times than those without a bougie (Macintosh, GlideScope).
• Skill level influenced intubation times, with advanced users generally performing faster.

Conclusions:

• The Seldinger technique is vital for endotracheal intubation, even in challenging situations.
• The novel laryngoscope offers a potentially reliable option for achieving rapid endotracheal intubation.
• Mastery of the Seldinger technique enhances airway management skills for all practitioners.
