Videolaryngoscopy vs. flexible fibrescopy for tracheal intubation in patients with cervical spine immobilisation: a randomised controlled trial
Authors' conclusion
When performing tracheal intubation in patients with a cervical collar, videolaryngoscopy with a non-channelled Macintosh blade was superior to flexible fibrescopy.
Study context
- Population
- Patients having elective cervical spine surgery with neck immobilised by a cervical collar to simulate a difficult airway
- Participants
- 166 vs 164
- Comparison
- Videolaryngoscopy vs flexible fibrescopy
- Videolaryngoscopen = 166
- Fibrescopen = 164reference
- Primary endpoint
- First attempt success rate of tracheal intubation
Primary result
As reported in the abstract
P = 0.003
Secondary outcomes
Time to tracheal intubation
P < 0.001
Use of additional airway manoeuvres
P < 0.001
Overall success of tracheal intubation within three attempts
- Successful within three attempts in all patients
Safety
Incidence and severity of intubation-related airway complications
- Not different between the two groups
