Airway Management Anesthesia View
Andreas Grabinsky, MDAssistant Professor, Dept. of AnesthesiologyProgram Director and Section Head, Emergency & Trauma AnesthesiaHarborview Medical Center
Overview
•Airway management in the field
•Airway management in the hospital
•Indications
•Priorities
•Problems
OR Airway Management
Field Airway Management
In the OR
OR Setting
•26 Operating rooms
•> 1.000 cases per month
•13 Anesthesiology Attendings
•26 Residents / CRNA’s
•Start 07:30AM (Wednesday 08:30AM)
•26 potential airways at 07:30AM
The OR Whiteboard
What to do ?•Find the Anesthesiologist in charge
•Find the anesthesiologist (covers 2-3 rooms)
•Help out
•Hope you “get the airway”
•Stay in one of the rooms (first rotation)
•Find a “late start room” for another airway (second rotation)
Learning Goals
•Identify difficult airway
•Proficient bag/mask ventilation
•Use of alternative airway techniques
•Prepare Intubation
•Learn about RSI
•Demonstrate Laryngoscopy / Intubation
The Intubator
Airway Priorities
1. Oxygenate2. Ventilate3. Protect Airway
Airway Management•Spontaneous ventilation
•Assisted mask/bag ventilation
•Controlled mask/bag ventilation
•Intubation + controlled ventilation
•Surgical airway + controlled ventilation
Use the least aggressive means necessary for airway management
Indications for Intubation
•Insufficient Oxygenation
•Insufficient Ventilation
•Loss of airway protection
•Impending airway problems (CNS, Trauma)
Preparation
•Oxygen
•Ambu bag with mask
•Suction
•Laryngoscope (working)
•different size ETT
•Suction
•Plan B (Adjuncts)
Prevention of Failure
•Assess situation
•Decision for specific airway management
•Communicate
•Plan B
•Reassess (change plan, if needed)
Failure to intubate in the OR
•Use alternative methods
•Get help
•Wake patient up
Failure to intubate in the Field
•Use alternative methods
•Failure is not an option !
Prevention of Failure
Do not mess with a perfectly fine airway.

Real Men use Miller Blades

Res-Q-Scope
Glidescope
Glidescope
Glidescope•25 Paramedic students
•Glidescope versus Macintosh 3 blade
•100 intubations in different scenarios on manekin
•Significant better visualized glotic opening with Glidescope
•Same success rate of 76%
•Increased time to intubation with GlidscopeAziz, Michael, Dillman, Dawn, Kirsch, Jeffrey R. and Brambrink, Ansgar(2009)'Video Laryngoscopy with the Macintosh Video Laryngoscope in Simulated Prehospital Scenarios by Paramedic Students',Prehospital Emergency Care,13:2,251 — 255
Res-Q-Scope•22 US military parmedic (50 manekin and 8
human intubations)
•22 Emergency medicine residents/attending
•20 minutes instruction and 20 minutes training, 3 trials with each device
•Intubation time Res-Q-Scope 25.9 seconds
•Intubation time direct Laryngoscopy 14.6 secondsShawn M. Varney MD , Melissa Dooley MD, Vikhyat S. Bebarta MD ⁎
