Brief Summary

Endoscopic retrograde cholangiopancreatography (ERCP) is an imaging procedure that visualizes the drainage ducts of the pancreas, gallbladder, and liver through the use of a duodenoscope and contrast media. By endoscopically identifying the ampulla of Vater, the common bile duct is cannulated. ERCP is also frequently utilized for therapeutic interventions, such as endoscopic sphincterotomy, bile duct stone extraction, stent placement in malignant and benign biliary strictures, and biopsy collection, thus playing a critical role in both the diagnosis and treatment of pancreatobiliary disorders. ERCP, being more invasive than routine upper endoscopies or colonoscopies, typically necessitates deeper levels of sedation. The procedure is performed in the prone, modified prone, or lateral decubitus position, which increases the risk of hypoxemia and hypoventilation due to upper airway obstruction. Furthermore, endoscopic instruments inserted through the oral cavity limit anesthesiologists' access to the patient's airway, thereby restricting ventilation support during gastrointestinal endoscopy. Ensuring airway stability during sedation is paramount for patient safety and procedural efficacy. Currently, a range of devices, including traditional nasal cannulas, high-flow oxygen masks, and procedural oxygen masks, are routinely employed to provide oxygen support throughout the procedure. The existing literature includes randomized controlled trials and systematic reviews aimed at preventing hypoxemia during ERCP. Through this study, investigators aim to make a novel contribution to the literature by assessing the effectiveness of a recently introduced procedural oxygen mask.

Outcome Measures

Primary Outcomes (1)

  • incidence of hypoxemia

    The incidence of hypoxemia during sedation (defined as SpO2 \< 90%). SpO₂ will be continuously measured using a pulse oximeter (GE Healthcare) to monitor and record oxygen saturation levels throughout sedation.

    Continuous SpO2 monitoring will be performed throughout the ERCP procedure

Secondary Outcomes (16)

  • Number of hypoxemia episodes

    Continuous SpO2 monitoring will be performed throughout the ERCP procedure

  • Duration of hypoxemia

    Continuous SpO2 monitoring will be performed throughout the ERCP procedure

  • Minimum SpO2 value observed during the procedure

    Continuous SpO2 monitoring will be performed throughout the ERCP procedure

  • Oxygen Reserve Index (as the baseline)

    Continuous Oxygen Reserve Index monitoring will be performed after prepreoxygenation

  • Oxygen Reserve Index (immediately after the start of the procedure)

    Continuous Oxygen Reserve Index monitoring will be performed throughout the ERCP procedure

  • +11 more secondary outcomes

Study Arms (2)

Group Nasal Cannula

ACTIVE COMPARATOR

Oxygen will be administered to this group via a conventional nasal cannula.

Device: Group Nasal Cannula

Group Procedural Oxygen Mask

ACTIVE COMPARATOR

Oxygen will be administered to this group via a Procedural Oxygen Mask.

Device: Group Procedural Oxygen Mask

Interventions

Oxygen administered during the endoscopic retrograde cholangiopancreatography (ERCP) procedure will be delivered through a conventional oxygen mask. The nasal cannula is a device that provides oxygen to patients through the nasal passages.

Group Nasal Cannula

Oxygen administered during the endoscopic retrograde cholangiopancreatography (ERCP) procedure will be delivered through a Procedural Oxygen Mask (POM® ELITE MF). The procedural oxygen mask is a device that covers both the mouth and nose to deliver oxygen to the patient. Its reservoir feature increases the concentration of delivered oxygen
