New airway management for painless gastroenteroscopy

Randomized Controlled Clinical Study of the Incidence of Hypoxia in a Novel Oropharyngeal Airway During Painless Gastroenteroscopy

Not applicable Interventional Qianfoshan Hospital · NCT06304337

This study is testing a new way to manage airways during painless gastroenteroscopy to see if it can keep patients, especially those who are obese or elderly, safer and more comfortable.

What this trial studies

This study investigates a new oropharyngeal airway management technique for patients undergoing painless gastroenteroscopy. The focus is on preventing airway obstruction during anesthesia, particularly in obese and elderly patients who are at higher risk for hypoxia. The study will monitor the incidence of hypoxia, cough, laryngeal spasm, and various adverse events, while also assessing endoscopist satisfaction and the required dosage of anesthetics. The goal is to enhance patient safety and comfort during the procedure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-95 with ASA physical status I or II and Mallampati grades I or II.

Not a fit: Patients with severe respiratory, cardiac, or renal conditions, as well as those with certain infections or bleeding disorders, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of airway obstruction and improve oxygenation during gastroenteroscopy.

How similar studies have performed: While similar airway management techniques have been explored, this specific approach using a new oropharyngeal airway device is relatively novel.
