Measuring gastric volume in obese patients using high-flow nasal oxygen therapy
Ultrasound Assessment of Gastric Volume in Paralyzed Obese Patients After High-flow Nasal Oxygen Therapy
This study tests how high-flow nasal oxygen therapy affects stomach size in obese patients before surgery to help keep them safe during anesthesia.

What this trial studies
This observational study evaluates the effects of high-flow nasal oxygen therapy on gastric volume in obese patients undergoing surgery with general anesthesia. It involves measuring gastric volume before and after the application of this therapy using ultrasound. The goal is to understand how preoperative preoxygenation influences gastric volume, which can be critical for patient safety during anesthesia. The study focuses on adult patients with a BMI of 30 kg/m2 or more.
Who should consider this trial
Good fit: Ideal candidates are adult patients with a BMI of 30 kg/m2 or more who are scheduled for surgery under general anesthesia.
Not a fit: Patients with severe cardiac or respiratory diseases, gastric reflux disease, or those who have had previous gastric surgery may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve preoperative care and safety for obese patients undergoing surgery.
How similar studies have performed: While similar studies on preoxygenation techniques exist, this specific approach using high-flow nasal oxygen therapy in obese patients is relatively novel.
