Background: Debates continue about the cricoid pressure, which has been used for many years to prevent gastric aspiration during intubation. By using ultrasound, the effects of this manoeuvre and alternatives like paralaryngeal pressure are revealed.

Objective: The aim of this observational study was to determine the effect of paralaryngeal pressure with ultrasound probe on the oesophageal diameter in patients with different body mass indexes and neck circumferences.

Methods: After measuring the neck circumference at the level of cricoid cartilage, the oesophagus was visualized by ultrasonography. A compression was applied medially at 45 ° angle towards the vertebral column by ultrasound probe and oesophageal anteroposterior outer diameters were measured. Correlations between body mass index, neck circumference, oesophageal diameter, oesophageal diameter change ratio were evaluated with Pearson's r value.

Results: 110 volunteers (52 women, 58 men) with mean age 33,7 ± 8,02 and mean body mass index 25,6 ± 4,65 kg.m-2 were recruited. Oesophagus was located 78,1% partially to the left, 4,5% completely to the left, 1,8% to the right of the cricoid ring. In 15,4% oesophagus could not be displayed. The mean diameter of the oesophagus was 7,6 ± 1,1 mm before pressure and 5,6 ± 0,09 mm after pressure (p<0,001). There was no significant correlation between diameter change percentage and body mass index (r= -0,22; p>0,05). However weak correlation was found between diameter change percentage and neck circumference (r= -0,33; p=0,016).

Conclusion: Paralaryngeal pressure with an ultrasound probe has the potential to occlude the oesophagus and may be effective in all patient groups.
