Use of a tube/anatomical measuring technique to increase proficiency of nasotracheal intubation

Airway management is a universal priority for critically ill and injured patients. Flight crews often perform nasotracheal intubation to secure patient airways prior to transport. The purpose of this study was to determine if a tube/anatomical measuring (TAM) technique, in conjunction with use of a directional-controlled tip endotube, would increase success rates of nasotracheal intubation. The performance of two groups of health professionals was evaluated. Group A consisted of 18 participants. This group nasotracheally intubated a mannequin twice, then learned and exercised the TAM technique during two additional intubation attempts. Group C consisted of 12 participants. Half of the group nasally intubated the mannequin twice without knowledge of TAM. The other six participants used TAM during two nasal intubation attempts. A statistically significant improvement in intubation success rates was noted when individuals from both groups used the TAM technique (p<=.01).
