Randomized Controlled Trial
Comparison of the Macintosh laryngoscope and blind intubation via the iGEL for intubation with cervical spine immobilization: A randomized, crossover, manikin trial.
Endotracheal intubation (ETI) using a Macintosh laryngoscope (MAC) requires the head to be positioned in a modified Jackson position, slightly reclined and elevated. Intubation of trauma patients with an injured neck or spine is therefore difficult, since the neck usually cannot be turned or is already immobilized in order to prevent further injury. The iGEL supraglottic airway seems optimal for such conditions due to its blind insertion without the need of a modified Jackson position. ⋯ We showed that blind intubation with the iGEL supraglottic airway was superior to ETI performed by paramedics in a simulated cervical immobilization scenario in a manikin in terms of success rate, time to definite tube placement, head extension angle, tooth compression, and rating.

Atlantodental interval (ADI), basion-dental interval (BDI) and the thickness of prevertebral soft tissue (TOPST) measured in lateral cervical radiographs were reported to be useful indicators and indirect signs of underlying cervical spine injuries. However, cervical computed tomography (MDCT) is the first method of imaging used in all trauma patients and upper normal limits (UNLs) of cervical distances according to age and sex are undetermined. Therefore, we aimed to calculate these metrics. ⋯ We believe that the increase in distances with age may be affected by the height losses of discs and vertebral bodies, formation of anterior osteophytes and regional kyphosis by age. Those results were compatible with the previous reports.
