Brief summary

After a structured teaching program anaesthetists are educated in identifying the cricothyroid membrane with ultrasonography. Thereafter their ability to do so is compared with their ability to do so with palpation. In an obese volunteer

Detailed description

Interventions

OTHERMarking the cricothyroid membrane after ultrasound

Ultrasonography is applied to the subjects neck in order to identify the cricothyroid membrane - subsequently the membrane is marked with a pen

PROCEDUREMarking of the cricothyroid membrane after Palpation

Palpation is applied to the subjects neck in order to identify the cricothyroid membrane- subsequently the membrane is marked with a pen
