Our data showed that even laryngoscopists with expert status  may frequently be confronted with severe ETI-related complications in both the prehospital and ED settings.
First, our study clarified the incidence and risk factors for ETI-related complications in trauma patients when expert laryngoscopists performed ETI in the ED and prehospital settings.
It is commonly believed that the force applied by laryngoscopists decreases as their technique improves with experience.
The reduction in applied force by laryngoscopists when using the GVL appears substantial, but it is unclear if this is clinically significant.
Airtraq vs standard laryngoscopy by student paramedics and experienced prehospital laryngoscopists
managing a model of difficult intubation.
Hastings et al (7) demonstrated that forces vary significantly between different laryngoscopists
dealing with the same patient, and our results support that forces exerted are not correlated with success.
I do not venture to express an opinion about the origin of the head-voice, which both Battaille and Garcia regard as a continuation of the falsetto, as even the physiologists and laryngoscopists
cannot agree as to its mechanism; but experience shows daily that it is different from that of the falsetto.
