Airway Management Anesthesia View Andreas Grabinsky, MD Assistant Professor, Dept. of Anesthesiology Program Director and Section Head, Emergency & Trauma Anesthesia Harborview 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. Oxygenate 2. Ventilate 3. Protect Airway
Use the least aggressive means necessary for 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 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 !
Do not mess with a perfectly fine airway. Prevention of Failure Do not mess with a perfectly fine airway.
