Overview

This study will assess the feasibility of using the TCI Articulating Device with video-laryngoscope in predictive, difficult airway, endotracheal intubation cases. It is meant to show the use of this device is equivalent to using the GlideRite Rigid Stylet with video-laryngoscope.

  1. History of difficult intubation
  2. History of head/neck radiation and prior oral cavity, pharyngeal, or laryngeal surgery

Group B Criteria (need three or more of the following)

1. Thyromental distance <6 cm (Defined as distance measured from the thyroid notch to the tip of the jaw with the head extended and the mouth closed)
2. Sternomental distance < 12 cm (Defined as distance measured as the straight line between the upper border of the manubrium sterni and the bony point of the mentum with the head in full extension and the mouth closed
3. Oropharyngeal view: modified Mallampati scale of 3 or 4
4. Mouth opening < 4 cm
5. Protruding upper teeth (severe overbite)
6. History of radiation to the neck
7. Limited neck movement: inability to extend and flex neck >90° from full extension to full flexion or presence of cervical spine pathologies and fractures (e.g., C-collar in place)
8. Body Mass Index (BMI) >35 kg/m2
9. Neck circumference .> 40 cm in females and 43 cm in males measured at the thyroid cartilage
