Preventing oxygen drops during ERCP with nasal PAP or capnometry

A Randomized, Controlled, Unblinded Trial Evaluating the Impact of Positive Airway Pressure and Capnometry Compared to Standard Management on the Rate of Desaturations During Nurse-administered Sedation ERCP

Not applicable Interventional Karl Landsteiner University of Health Sciences · NCT07056075

We'll try whether using nasal positive airway pressure or capnometry with low-flow oxygen during sedated ERCP reduces oxygen drops in adults receiving nurse-administered sedation.

What this trial studies

This interventional study compares different respiratory management and monitoring approaches during interventional ERCP performed with nurse‑administered sedation. Adults (18–99) undergoing ERCP are assigned to receive nasal positive airway pressure ventilation, capnometry monitoring with low‑flow oxygen, or standard low‑flow oxygen, and are followed for desaturation events and other respiratory complications. Continuous cardiorespiratory data are collected during and immediately after the procedure to compare frequency and severity of hypoxemic episodes between groups. The study is conducted at two Austrian centers (Medical University of Graz and University Hospital of St Pölten).

Who should consider this trial

Good fit: Adults aged 18–99 who are scheduled for an interventional ERCP under nurse‑administered sedation, are not pregnant, and do not require planned intubation or anesthesiologist backup are the intended participants.

Not a fit: Patients who require general anesthesia or intubation, have a tracheostomy, are pregnant, or have a known propofol allergy are excluded and unlikely to benefit from these interventions.

Why it matters

Potential benefit: If successful, these approaches could reduce the rate and severity of sedation-related oxygen drops during ERCP and improve patient safety without needing more general anesthesia resources.

How similar studies have performed: Capnography has been shown to detect hypoventilation earlier than pulse oximetry in endoscopy settings, but evidence that monitoring or adjunctive nasal PAP consistently reduces serious clinical outcomes is limited and nasal PAP use during ERCP is less well studied.
