The purpose of the pilot study is to compare new laryngoscopes for infants by assessing the equipment best suited to assist the intubation, with the best overview, shortest time to intubation and use these numbers to make a sample size calculation for the full protocol. The investigators hypothesis is that the Storz videolaryngoscope® has a better success rate than infants (<2 years). The patients will be optimally anaesthetized with neuromuscular blockade for the intubation. All patient will be evaluated with af Macintosh blade laryngoscope, with an Airtraq® or a Storz videolaryngoscope®, and finally intubated with the other one of the later, which the patient was randomized to.

Primary Outcome Measures:
  • Success rate [ Time Frame: 5 minutes ] [ Designated as safety issue: No ]
    Succes is defined by intubation being executed in the first try.

Secondary Outcome Measures:
  • Time to Cormack evaluation [ Time Frame: 5 minutes ] [ Designated as safety issue: No ]
  • Time to intubation [ Time Frame: 5 minutes ] [ Designated as safety issue: No ]
  • Number of intubation attempts [ Time Frame: 5 Minutes ] [ Designated as safety issue: No ]
  • Quality of laryngeal overview before intubation [ Time Frame: 5 Minutes ] [ Designated as safety issue: No ]
    Evaluated by Cormack score

  • Prevalence of post intubation stridor [ Time Frame: 12 hours ] [ Designated as safety issue: No ]
  • Intubation conditions [ Time Frame: 5 Minutes ] [ Designated as safety issue: No ]
