Study Overview

Brief Summary

Hypoxia represents the prevailing adverse occurrence during the sedation of patients undergoing Endoscopic Retrograde Cholangiopancreatography (ERCP) with propofol. A recent innovation in this domain is the COMBO Endoscopy Oropharyngeal Airway-a multifaceted device that encompasses capnography monitoring, bite block , oxygenation support, and oropharyngeal airway management. This device has been purposefully designed to cater to the unique requirements of endoscopic procedures. The principal objective of this study is to assess the efficacy of the COMBO Endoscopy Oropharyngeal Airway in reducing the incidence of hypoxia in patients undergoing ERCP under sedation.

  • Child-Pugh class C;
  • Diagnosed chronic obstructive pulmonary disease (COPD) or other acute/chronic pulmonary diseases requiring long-term/intermittent oxygen therapy;
  • Increased intracranial pressure;
  • Upper respiratory tract infections (oral/nasal/pharyngeal);
  • Fever (core temperature >37.5°C);
  • Confirmed pregnancy or current breastfeeding;
  • Allergy to sedatives (e.g., propofol) or medical adhesives;
  • Emergency procedures;
  • Multiple trauma injuries;
  • Peripheral oxygen saturation (SpO2) levels below 95% while breathing room air preoperatively;
  • BMI <18.5 or >30 kg/m²;
  • Current participation in other clinical trials;
  • Other conditions deemed ineligible by investigators.

Outcomes
