Brief summary

Verify in ultrasound the impact of a Sellick and LPEC manoeuvre in terms of compression of the carotid artery and decrease in vascular flow.

Interventions

PROCEDUREUltrasound LPEC/Sellick

We will perform an ultrasound of the carotid artery and then apply a Sellick manoeuvre and a left paratracheal compression of the cervical esophagus respectively.

Design outcomes

Primary

Measure	Time frame	Description
Compression of the carotid artery during an esophageal compression manoeuvre	through study completion, an average of 1 month	Measurement of the diameter of the carotid artery in cross-section and longitudinal section
Vascular flow of the carotid artery during an esophageal compression manoeuvre	through study completion, an average of 1 month	Measurement of systolic velocities in pulsed Doppler in the carotid artery

Secondary

Measure	Time frame	Description
Measurement of the force to be applied to compress the esophagus without compressing the carotid artery	through study completion, an average of 1 month	use of a dynamometer to measure the force required to exert at the left paratracheal level
