title: A comparison of two tracheal intubation techniques with Trachlight and Fastrach in patients with cervical spine disorders.
abstract: Optimal airway management strategies in patients with an unstable cervical spine remain controversial. A newly designed lightwand device (Trachlight) or an intubating laryngeal mask (Fastrach) may avoid hyperextension of the neck. However, there are few objective data that guide us in selecting the appropriate devices. We conducted a prospective randomized study in 148 patients who received general anesthesia for whom the operations were related to the clinical and/or radiographic evidence of cervical abnormality. Trachlight or Fastrach was used for tracheal intubation with the head and neck held in a neutral position. In the Trachlight group, intubation was successful at the first attempt in 67 of 74 (90.5%) cases and at the second attempt in 5 (6.8%) cases. In contrast, in the Fastrach group, 54 of 74 (73.0%) patients were intubated within our protocol. The mean time for successful tracheal intubation at the first attempt was significantly shorter in the Trachlight group than in the Fastrach group. The Trachlight may be more advantageous for orotracheal intubation in patients with cervical spine disorders than the Fastrach with respect to reliability, rapidity, and safety.
  
  
  CONCLUSIONS
  The Trachlight may be more advantageous for orotracheal intubation in patients with cervical spine disorders than the Fastrach with respect to reliability, rapidity and safety.
