In the operating-room randomised comparison of starting with a hyperangulated videolaryngoscope versus direct laryngoscopy, give the rate of needing more than one intubation attempt and the rate of intubation failure in each group, and state what was found for airway and dental injury.
Answer: Starting with a hyperangulated videolaryngoscope cut the need for more than one attempt from 7.6% to 1.7% and intubation failure from 4.0% to 0.27%, with no difference in airway or dental injury.
Fewer attempts and fewer failures, and no difference in airway or dental injury — that is the case for reaching for the hyperangulated scope first.

In a multicentre randomised trial restricted to patients with no predicted difficult airway, compare first-pass intubation success and the incidence of a Cormack-Lehane grade of 3 or worse between a Macintosh-bladed videolaryngoscope and conventional direct laryngoscopy.
Answer: First-pass success was 94% with the Macintosh-bladed videolaryngoscope versus 82% with direct laryngoscopy, and a Cormack-Lehane grade of 3 or worse fell from 8% to 0.7%.
Even in airways with no predicted difficulty, the Macintosh-bladed videolaryngoscope gave a better view and a higher first-pass success rate.

Multidisciplinary recommendations advise universal videolaryngoscopy. How many statements do they contain, what were those statements mostly formulated from, why was that, and how strongly can you therefore cite them?
Answer: The recommendations rest on 12 statements that were mostly formulated from expert opinion, because the quality of the available evidence was low; they should therefore be cited as consensus expert opinion rather than as high-quality evidence.
Twelve statements built mostly from expert opinion because the evidence quality was low — quote them as consensus, not as proof.

Summarise what videolaryngoscopes of every design achieve compared with direct laryngoscopy, and state specifically what the hyperangulated designs add.
Answer: Videolaryngoscopes of every design reduce failed intubation and improve first-attempt success and glottic view; the hyperangulated designs are the ones that reduce oesophageal intubation and that help most in patients with difficult airway features.
Every design improves the view and first-attempt success, but reducing oesophageal intubation and helping most with difficult airway features is specific to the hyperangulated blades.
Source claim: Videolaryngoscopes of every design reduce failed intubation, improve first-attempt success and glottic view, and hyperangulated designs are the ones that reduce oesophageal intubation and help most in patients with difficult airway features.

Macintosh-style videolaryngoscopy probably reduces failed intubation rates compared to direct laryngoscopy (RR 0.41, ___% CI 0.26 to 0.65).
Answer: 95
Macintosh-style videolaryngoscopy probably reduces failed intubation rates compared to direct laryngoscopy (RR 0.41, 95% CI 0.26 to 0.65).
