A colleague argues against awake tracheal intubation in an anticipated difficult airway on the grounds that it takes too long and is risky. Using the retrospective data on time, failure and complications for awake intubation versus intubation after induction, what is the actual cost of choosing awake intubation?
Answer: The cost is time, not safety. Awake intubation took a median of 24 minutes from entering theatre versus 16 minutes for intubation after induction, with a 1% failure rate and 1.6% complications.
Roughly eight extra minutes is the real price of an awake intubation, and that is a cheap thing to spend on an airway you are worried about.
Source claim: Awake intubation took a median of 24 minutes from entering theatre against 16 minutes for intubation after induction, with a 1% failure rate and 1.6% complications — it costs time, not safety.

Among the airway devices compared in a network meta-analysis of awake tracheal intubation in adults — flexible bronchoscopes, videolaryngoscopes and optical stylets — which device gave the shortest time to tracheal intubation?
Answer: Optical stylets resulted in the shortest time to tracheal intubation compared with flexible bronchoscopes and videolaryngoscopes during awake tracheal intubation.
The network meta-analysis ranks optical stylets fastest for awake intubation — speed is the outcome that separated the devices here.
Source claim: Optical stylets result in the shortest time to tracheal intubation compared to flexible bronchoscopes and videolaryngoscopes during awake tracheal intubation.

You are choosing between a videolaryngoscope and a flexible bronchoscope for an awake tracheal intubation. Based on the pooled randomised trials comparing these two approaches, which outcomes favour videolaryngoscopy and which outcomes showed no difference?
Answer: Videolaryngoscopy shortened intubation time compared with flexible bronchoscopy and slightly reduced desaturation below 90%. There was no difference in failure rate or in first-attempt success.
Videolaryngoscopy for an awake intubation buys you speed and a little less desaturation, not a better chance of getting the tube in.
Source claim: For awake tracheal intubation, videolaryngoscopy shortened intubation time compared with flexible bronchoscopy and slightly reduced desaturation below 90%, with no difference in failure or first-attempt success.

Awake intubation was used in about 1% of general anaesthetics and that rate did not fall over ___ years despite a large rise in videolaryngoscopy, with 2% of attempts failing.
Answer: 12
Awake intubation was used in about 1% of general anaesthetics and that rate did not fall over 12 years despite a large rise in videolaryngoscopy, with 2% of attempts failing.
