Brief Summary:
The investigators aim to compare the new paediatric Airtraq indirect optical laryngoscope with conventional direct laryngoscopy for tracheal intubation in a randomised crossover study during routine anaesthesia. The investigators hypothesise that the Airtraq is as good as conventional laryngoscopy for tracheal intubation of infants and children. This will be an equivalence rather than a non-inferiority study.

Condition or disease Intervention/treatment Phase
Children General Anesthesia Intubation Device: Airtraq laryngoscopy Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Official Title: Randomised Controlled Trial of the Airtraq Optical Laryngoscope and Conventional Laryngoscopy in Children
Study Start Date : August 2010
Actual Primary Completion Date : March 2011
Actual Study Completion Date : March 2011

Arm Intervention/treatment
No Intervention: Conventional
conventional laryngoscopy for intubation
Experimental: Airtraq
laryngoscopy with Airtraq for intubation
Device: Airtraq laryngoscopy
laryngoscopy and intubation

Primary Outcome Measures :
  1. time taken to successful intubation [ Time Frame: 30 mins ]
    The primary outcome measure will be time taken to successful intubation. This will be recorded by a second operator using a handheld stopwatch or wall clock with second hand. Time will commence when the intubation device is handed to the anaesthetist, and stopped after the first successful inflation of the lungs (first upstroke of capnography trace).

Secondary Outcome Measures :
  1. Grade of laryngoscopy [ Time Frame: 30 mins ]
  2. POGO score [ Time Frame: 30 mins ]
  3. VAS ease of intubation [ Time Frame: 30 mins ]
  4. evidence of traumatic intubation [ Time Frame: 24 hours ]
