Trial summary
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… Read more about this study

About this study
Official title: Supraglottic Oxygenation Via Oral Transtracheal Catheter for Reducing the Incidence of Hypoxemia During ERCP Under Sedation：a Randomized Controlled Trial
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
