About this study

Endoscopic retrograde cholangiopancreatography (ERCP) procedures are commonly performed under deep sedation and are associated with a risk of hypoxemia, particularly in prone or semi-prone positions. High-flow nasal cannula (HFNC) therapy may improve oxygenation by delivering heated and humidified oxygen at high flow rates, while the Microstream Advance nasal cannula provides simultaneous nasal oxygen delivery and oral oxygen insufflation.

This prospective randomized study aims to compare the effectiveness of HFNC and Microstream Advance nasal cannula in maintaining oxygenation during ERCP procedures. Patients undergoing ERCP will be randomized into two groups receiving either HFNC or Microstream Advance nasal cannula oxygen support during sedation.

The primary outcomes are the incidence of desaturation and oxygen reserve index (ORi) measurements during the procedure. Secondary outcomes include time to achieve target ORi levels, respiratory complications, and procedure-related adverse events.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • High-flow nasal canulaDevice

    Heated and humidified high-flow oxygen therapy delivered through a nasal cannula during ERCP under sedation

  • Microstream advance nasal cannulaDevice

    Oxygen support delivered through the Microstream Advance nasal cannula during ERCP under sedation.

Questions about this trial

What is this clinical trial studying?

A study testing High-flow nasal canula and Microstream advance nasal cannula in people with Endoscopic Retrograde Cholangiopancreatography and Hypoxemia, run by Kocaeli University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 15 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Volkan Alparslan, M.D. (05059374578, volknn@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Desaturation During ERCP (time frame: During the ERCP procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jul 2026.
