What About Compressing the Oesophagus with an Ultrasound Probe for a Modified Sellick Maneuver?

Abstract

Objective: Debates continue about the cricoid pressure, which has been used for many years to prevent gastric aspiration during intubation. Using ultrasound, the effects of this maneuver and alternatives like paralaryngeal pressure are revealed. The aim of this observational study was to determine the effect of paralaryngeal pressure with an ultrasound probe on the oesophageal diameter in patients with different body mass indexes and neck circumferences.
