Candidates’ ability to intubate with the Mackintosh laryngoscope (scenario A) and the intubating laryngeal mask airway (scenario B)

Candidate	Ability to intubate with Mackintosh laryngoscope	Ability to ventilate using the ILMA	Time to successful ventilation with the ILMA (s)	Ability to intubate using the ILMA	Time to successful intubation with the ILMA (s)	Number of attempts at intubation with the ILMA	Time from ventilation to intubation ILMA (s)
* ILMA, intubating laryngeal mask airway. Indicates where repositioning of the ILMA was required. Candidates 15, 17 and 22 required 2, 1 and 1 reposition(s) of the ILMA, respectively.
Ability to successfully intubate using the Mackintosh laryngoscope in scenario A was 0% vs 100% for the ILMA (p<0.001). Ventilation with the ILMA was possible in all cases.
