Brief Summary

The simplicity of use and intuitive function of the McGrath video-laryngoscope suggests it may have a bigger role than as a back-up to conventional direct laryngoscopy and could possibly be the first-line laryngoscope for situations where difficult intubations are more likely or more hazardous. The incidence of difficult or failed intubation for an individual anaesthetist is related to their experience, decreasing as experience increases. The purpose of this trial is to evaluate the McGrath laryngoscope when used by relatively inexperienced anaesthetists, who are those most likely to encounter difficulties.

The null hypotheses to be tested is that there is no difference between the Macintosh and McGrath laryngoscope in terms of ease and success in intubation.
