Do You See Anything That You Recognize: Teaching Novice Student Registered Nurse Anesthetists to
Intubate Using the GlideScope
Stephanie K. McHenry, CRNA, MSN, ARNP
Introduction
• CRNAs in US provide over 33 million anesthetics safely to patients’ annually (American Association of Nurse Anesthetists ,2011)
• Endotracheal intubation – Most crucial skill for CRNA– Difficult to Master (Howard-Quijano, K. J., Huang, Y. M., Matevosian, R., Kaplan,
M. B., & Steadman, R. H, 2008)
• 50 intubations to achieve 90% success rate on Mallampati I and II (Konrad, C., Schupfer, G., Wietlisbach, M., & Gerber, H. ,1998) – Variables associated with anatomic landmarks of real patients– Anatomic drawings and manikin modules do not adequately represent anatomy
• Novice success rate 45% for first 10 intubations (Ayoub, C. M., Kanazi, G. E.,
Al Alami, A., Rameh, C., & El-Khatib, M. F., 2010). – affects confidence levels – Influences performance in other areas of clinical experience (Chipas, A., Cordrey,
D., Floyd, D., Grubbs, L., Miller, S., & Tyre, B., 2012, August)
Introduction • Endotracheal intubation difficult skill to teach (Howard-Quijano, K. J,
2008)– Restricted time– Limited visual perspective
• Video Laryngoscope (VL) as a teaching aide (Kaplan, M. B., Ward, D., Hagberg, C. A., Berci, G., & Magiike, M., 2006) – Reduces instructor and student frustration– Allows simultaneous visualization of airway– Shortens student’s intubation learning phase (Herbstreit, F., Fassbender,
P., Haberl, H., Kehren, C., & Peters, J. 2011) – Skills developed to use during difficult intubations (Herbstreit, F., 2011)
• Previous research examined use of VL to teach EMTs and doctoral students with success
• No research published implementing the VL as a instructional aid for SRNAs.

Excluded case studies, reviews and letters to the editor
Excluded
Records Excluded (n= 593) Non-peer review journals, not available in English or duplicate studies

Additional records identified through other sources (Cohrane Database, dissertation abstracts, IBIS, Reference in other articles (n =536)
Results• Video-assisted techniques used to teach many
surgical disciplines• Several types of Laryngoscopes are used by
Anesthesia (Kaplan, 2006)
• Benefits of Laryngoscopes to teach intubation– Used for difficult intubations– Improved intubation success rate (Kaplan, 2006) (Herbstreit,
2011)
– Less time to intubation (Ayoub, 2010)
– Increased knowledge of anatomy (Low, 2008)
– Decreased number of attempts to obtain a level of competency (Howard-Quijano, 2008) (Nouruzi-Sedeh 2009)
Integrative Review : Using the Video Laryngoscope to Aide Tracheal Intubation Instruction
Type of Video Laryngoscope Used in Research Studies
Teaching ModuleIntubation Video
3, 11,13
*Show 15 actual laryngoscopes via view from intubator
*Shows all anatomical structures in sequence
*Allow online access to video
Lecture
3,11,12, 13
*Airway Anatomy
*Proper Intubation/Positioning techniques
*Airway Management
*How to use the GlideScope
*Familiarization with Equipment
Simulation /Mannequin
3, 8,11, 12, 13 ,18
* "Easy" simulator first
* Feedback on technique
* Repeat until able to demonstrate consistent
satisfactory performance
* Introduce difficult intubation scenarios as well
as expose to alternative difficult intubation aids
Clinical Practice- Macintosh Blade
11,12
* 5 intubations
* Allows for proper equipment setup
* Experience intubating actual patient
* If student cannot visualize cords about
attempt and ventilate
Clinical Practice - Video Laryngoscope
2, 3, 11,12
*10 intubations
* Best opportunity to visualize anatomical
structures
Return to Macintosh Blade
* Video Laryngoscope used for anticipated
or encountered difficult airways
Competence and Confidence
3,8, 11
* Air management skills
*Use of Video Laryngoscope
Summary
• Monocularity causes students to struggle to learn the skill of intubation using the traditional laryngoscope
• Slight anatomical differences may impede successful laryngoscopy.
• Implementing the Video Laryngoscope as a teaching tool– Provides instantaneous feedback– Leads to increased proficiency– Improves learning– Increases competence– Improves patient safety
