MRI STUDY OF THE LPEC

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.

Procedure

we aim to asses with an magnetic resonance imaging the compressibility of the oesophagus with LPEC

Primary outcomes

  1. Oesophagus compressibility

    Time frame: End of the MRI

    Analysis of the position of the Oesophagus is obtained in the three groups in a upper position ( C5-6) and lower position (C8-T1). The upper position is the first view were the oesophagus is clearly identified: In fact, the pressure exerted during the cricoid maneuver is in fact applied in the area of the hypopharynx above the osophagus. The oesophagus is quoted relatively to the vertebral body as Medial (80% facing the vertebral body) Medio-lateral , lateral (20% facing the vertebral body).
