#3 Intro to EM Airway Management- Assessment and SupraGlottic Airways (SGA) Andrew Brainard 1
#3 SupraGlottic Airway Learning Objectives: – Briefly describe plan, assign roles Declare “Crash Airway” Skip checklist Continue Chest Compressions Place SupraGlottic Airway – Proper sized LMA/AirQ – Proper insertion (<30sec) – Troubleshoot cuff leak – Tube confirmation Discuss – Crash vs Emergent vs Semi-elective – Advantages/Disadvantages of SGAs – Indications for SGA, RSI, ETT Safe removal of SGA – Formal Airway Assessment – MOANS/LEMON/RODS – Specific briefing for Plan A, B, C, & D – Suction – Leave Cuff Up – Remove under direct visualization Bell in Short Stay: – 60y/o M, chest compressions in progress on patient admitted with chest pain – On floor unresponsive – GCS 3, No pulse, CPR in progress, – Unobtainable SaO2 – Difficulty with BVM seal (beard, small jaw, no neck, emesis, high resistance) Crash SGA during compressions – Insert SGA – Oxygenate and Ventilate through SGA – Get ROSC – Transfer to resus – Intubate through SGA – Discuss removing SGA Formal Airway Assessment – MOANS – LEMON – RODS – SHORT
Using SuperGlottic Airways (SGA) Air Q Fastrack I-LMA Indications Predicting difficult (RODS) Sizing Insertion Procedure Troubleshooting Intubating through an SGA 3
Indication(s) – Rescue Airway – Rescue Oxygenation – Anywhere on the Algorithm – Replacing Inadequate BVM – During CPR/compressions – For Pre-Oxygenation before Laryngoscopy (Rapid Sequence Airway) – After unsuccessful Laryngoscopy – Before/during cric 4 SGA/LMA
Intubating LMA (Fastrack) #3- Small Adults 30-50kgs #4- Most Adults50-70 kgs #5- Large Adults kgs AirQ #1.0- Infant <7 kgs #1.5- Toddler 7-17 kgs #2.0- Child kgs #2.5- Small Adult30-50kgs #3.5- Most Adults50-70 kgs #4.5- Large Adult kgs Ideal Body Weight (height) 5
Predictors of Difficult SGA RODS – R: restricted mouth – O: obstruction – D: disrupted or distorted airway – S: stiff lungs or c-spine 6
AirQ Insertion – Lubricate – Leave red tag on pilot balloon – Lift tongue Finger/Laryngoscope/Tongue depressor – Can use finger to assist around the corner – Jaw lift – Position incisors between 2 insertion marks Add ~5 cc’s of air. Minimizing Leaks – Neutral head position – Use jaw lift – Don’t over-inflate – Check position While inflated, pull back 1-3cm – Change size – Check ETCO2 waveform How to use a AirQ 0a1KYwfDk0http:// 0a1KYwfDk0 (9 minutes) 7
Supraglottic Airway (SGA) Prepare/position airway Lubricate and deflate cuff Pull the jaw and tongue forward – Finger – Laryngoscope – Tongue depressor Insert the LMA – Press against hard palate – Advance until resistance Inflate the cuff – Poor seal may indicate over inflation. Ventilate the patient with PEEP Confirm placement – ETCO2 – Chest Rise – Listen for Leak 8
Troubleshooting SGAs Get best possible seal – Over-inflation is frequently the cause of leaks – Usually Too deep – Test airway pressures – Watch ETCO2 trace Chandy maneuver, – Rotate Sagittal Coronal – Lifting Toward ceiling 9
Intubating through the LMA Place LMA Ventilate – Relax Insert ETT Reattach BVM to ETT – Ventilate w/ETCO2 Size ETT/I-LMA – Lubricate tube – Test ETT fit Confirm placement – Ventilate w/ ETCO2 – Confirm tube placement – Inflate ETT cuff Advance ETT – Applying upward pressure on the LMA – Ventilate w/ ETCO2 – Advance ETT through cords Removing the LMA is optional Verify placement – ETCO2 – Listen for leak 10
Airway briefing and checklist CPR with chest compressions and BMV are in progress. We are having difficulty assuring oxygenation with a BVM This is a crash airway Continue Chest Compressions Place the I-LMA #5 Continue Chest Compressions Our plan is: A- Continue to attempt to BVM B- Place I-LMA #4 (now) C- Direct/bougie/7.5 tube once we have ROSC or some more time D- Cric if we get ROSC but can not get an airway Questions? Oxygenate the patient 11
