Ultrasound-Guided Esophageal Compression During Mask Ventilation in Adults

This clinical study aims to explore a new method for improving mask ventilation in adults during surgery. It focuses on using ultrasound to guide esophageal compression, which could potentially reduce the risk of stomach contents entering the lungs during ventilation. The study involves adult patients who are undergoing surgery and require ventilation with a face mask. The main goal is to see if applying pressure to the esophagus can enhance the effectiveness of mask ventilation, thereby improving patient safety during surgical procedures. Participants in the study receive oxygen through a face mask and a series of medications to induce unconsciousness. The study involves two groups: one receives the standard mask ventilation, while the other has ultrasound-guided pressure applied to the esophagus during ventilation. The size of the stomach is measured using ultrasound before and after ventilation to assess any changes. The study carefully monitors vital signs and uses video laryngoscopy to record the ease of intubation. This process helps evaluate the effectiveness of the esophageal compression technique in maintaining clear airways and preventing regurgitation during surgery.
