Endoscopic retrograde cholangiopancreatography (ERCP) is commonly used for the diagnosis and treatment of pancreatobiliary diseases. While Monitored Anesthesia Care (MAC) enhances the efficiency of ERCP, deep sedation introduces significant airway risks, particularly hypoxemia resulting from sedative-induced upper airway collapse. With reported hypoxemia rates ranging from 10% to 69%, and the potential for severe complications such as myocardial ischemia and neurological damage, effective airway management is paramount. Supraglottic oxygenation via oral transtracheal catheter provides a viable method for relieving obstruction and enabling positive pressure ventilation, serving as a less invasive alternative to tracheal intubation. Despite its proven utility in other settings, this technique has not yet been evaluated in the context of deeply sedated ERCP.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
