Summary

A total of 103 elective surgery patients who met the inclusion criteria were selected. After screening for eligibility according to the inclusion and exclusion criteria and signing informed consent, they were randomly divided into two groups. Upon entering the operating room, routine ECG monitoring was initiated, and a peripheral vein was opened. Ultrasound was used to measure the baseline cross-sectional area (CSA) of the gastric antrum in the supine position. After general anesthesia induction, positive pressure ventilation was applied via face mask. Group A received no external compression, while Group B underwent esophageal compression under ultrasound guidance.

Conditions

  • Laparoscopic Surgery
  • Ultrasonography
  • Compression of Esophagus
  • Stomach Distended

Interventions

BEHAVIORAL

Compression of esophageal

Before the start of FMV, ultrasound is used to locate the esophagus, and pressure is applied to the esophagus at the cricoid level to collapse the esophageal lumen. Esophageal pressure is released just before tracheal intubation following 4 minutes of ventilation.
