Is this a successful airway ?
The point isThe point is...The goal in airway management isThe goal in airway management is
OXYGENATION and VENTILATION
...by any means: BMV, EGD, ETT(most definitive is a cuffed ETT)
Definitions and Drugs
• Rapid Sequence Induction (OR)– Intubated to provide anesthesia
• Rapid Sequence Intubation (ED)– Anesthetized/paralyzed to facilitate
intubation

Is it ?
• Penetrating neck injury is only a ‘marker’ for airway injuryairway injury
• Is RSI safe with a penetrating neck injury ?I RSI f ith t ti i i j ?• Is RSI safe with a penetrating airway injury ?
• IF using an RSI:– Don’t mask vent – No blind device use
G t it 1 t tt t– Get it on 1st attempt

Pushing on the thyroid cartilage usually helpsthe view…With ELM/BURP most patients improved one fulllaryngoscopic grade.
Benumof JL et.al. J. Clinical Anesthesia 1996
P hi th i id tilPushing on the cricoid cartilage may worsen the view …With Cricoid pressure (not ELM/BURP)worsens DL view in 30% of cases
