Brief summary

Effect of semirigid cervical collar during nasotracheal intubation by Glidescope in the elective cervical spinal surgical patients: a study of clinical predictors and outcomes

Detailed description

Clinically used cervical orthoses can effectively limit cervical spine motion in all direction and provide protection. Among them, the restriction by Miami semirigid collar was superior, with the least tissue-interface pressure of neck. It is one of the most used semirigid collars for patients' protection in the operating theatre. However, the presence of the semirigid collar was shown to result in a poorer view at laryngoscopy, possibly due to a reduction in mouth opening. Nasotracheal intubation is sometimes applied in cervical spinal surgeries for those receiving anterior approach for a higher cervical spine (C3) level, and/ or combined with a short neck, or due to surgeon's preference. Glidescope minimizes cervical movements during laryngoscopy, facilitates nasotracheal intubation than direct laryngoscopy and requires less technical skill than fiberoptic tracheal intubation. The investigation was to assess the effect of cervical collar on nasotracheal intubation and potential hazard factors of prolonged time for nasotracheal intubation with Gildescope in patients scheduled for elective cervical spinal surgery.

Masking description

The anesthetic induction and nasotracheal induction are performed by one anesthesiologist. Another anesthesiology calculated the intubation time according to the video recording.

Intervention model description

The patients are randomized into one of the two group: the collar group or the non-collar group before anesthetic induction. In the collar group, the patient was put on a Miami cervical collar and then anesthetic induction and nasotracheal intubation are performed. the non-collar group receive the same anesthetic care without a collar as a control.
