Brief summary

To prevent bronchial aspiration during induction of anaesthesia it has been a common procedure to perform a cricoid pressure, called Sellicks Maneuver, to occlude esophagus, and thereby prevent aspiration. During the last ten years the efficiency of this maneuver has been discussed, since it probably prolong the intubation time and do not significantly reduces the risk of aspiration. The hypothesis is that Sellicks Maneuver prolong the time of intubation and reduces the view of the laryngeal inlet, during intubation with a videolaryngoscopy. The hypothesis is tested by a double-blinded randomized study where patients is intubated twice, with and without Sellicks Maneuver, in a randomized order. The specific cricoid pressure is blinded to the personal performing the intubation.

Interventions

PROCEDURECricoid pressure

The patient is intubated twice, once with a cricoid pressure and once with a sham-pressure, when performing a videolaryngoscopy.

Design outcomes

Primary

Measure	Time frame	Description
Completed intubation within 120 seconds	120 seconds	The primary outcome measure is the rate of completed and failed intubations. A intubations is failed when the oxygen saturation is less then 95% or the intubation time is longer then 120 seconds.

Secondary

Measure	Time frame	Description
A description of the laryngeal inlet	120 seconds	The secondary outcome measure is a description of the laryngeal inlet according the the Cormack-Lehan system, and how Sellicks Maneuver alters that view.
