MRI Clinical Trial
Official title:
Evaluation in MRI of the Impact of the Sellick Manoeuvre or Para-tracheal Compression of the Cervical Esophagus on the Displacement of the Laryngeal Mass and the Visualization of the Vocal Cords
Cricoid pressure is still considered as a standard of care in order to prevent the gastric
regurgitation in full stomach surgery1.
However, this attitude has been challenged in several case reports as oesophageal rupture,
difficult intubation, and even failing to occlude the oesophagus. Moreover, in a large
prospective randomized study , this maneuver has failed to show a definite benefit2.
The lateral deviation to the left of the oeso deviate to the left side3,4 has led to the
description of a new maneuver to compress directly the oesophagus at the low left
paratracheal level. This maneuver has been shown to prevent gastric air insuflation during
the ventilation.
In the present study, the investigators aim to asses with an magnetic resonance imaging the
compressibility of the oesophagus.
