Fibreoptic Intubation With and Without Sellick´s Maneuver

The patients included in this study has volunteered after sufficient information, and must be ASA-class I-II, 18 years or more, and must not have indications for a rapid sequence induction. The patient will be intubated twice, with and without Sellick´s maneuver. It is blinded to the intubating physician, in which order this pressure is applied. The outcomes measures will be time of intubation, oxygen saturation before and after intubation and a Cormack Scale graduation of the visibility of the vocal cords. The intubation will be failed, if it cannot be performed under 120 seconds, or if the patients desaturate to 95% or less.
