An interventional study of ultrasound examination of air insufflation in the upper esophageal region and stomach in Gastric Insufflation, sponsored by SMG-SNU Boramae Medical Center. Status unknown. Open to participants aged 20 Years and older. Per ClinicalTrials.gov, last updated 2021-07-16.
Sponsored by SMG-SNU Boramae Medical Center · Not applicable, Interventional, and Prevention
Effect of peak inspiratory pressure on the gastric insufflation is evaluated using ultrasonography during face mask ventilation in obese adults. Effect of facial mask holding techniques on the gastric insufflation is also evaluated.
SMG-SNU Boramae Medical Center is the lead sponsor of 38 studies on the registry; 6 are open to participants now.

Diagnostic Test: ultrasound examination of air insufflation in the upper esophageal region and stomach
Presence of air insufflation is assessed using ultrasound in the upper esophageal region and stomach during face mask ventilation
Presence of gastric insufflation in the epigastric region
Under ultrasound, air signal is assessed in the epigastric region
Time frame: During anesthesia induction
Cross-sectional area of the antral cross-sectional area
During ultrasound examination, anterior-posterior diameter and cranio-caudal diameter of the antrum are measured. Cross-sectional area of the gastric antrum is calculated as follows; (AP × CC × π)/4 (AP=antero-posterior diameter and CC=cranio-caudal diameter).
Time frame: During anesthesia induction
Presence of gastric insufflation in the upper esophageal region
Under ultrasound, air signal is assessed in the upper esophageal region.
Time frame: During anesthesia induction
Expiratory tidal volume
Expiratory tidal volumes displayed on the monitor of the anesthesia machine are recorded.
Time frame: During anesthesia induction
