What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study compares three recovery positions—side-lying with head up, lying on back with head up, and standard side-lying—to see which best prevents low oxygen levels after painless stomach and colon exams. Over 1,600 adults will be randomly assigned to one position. The goal is to find a simple, non-invasive way to improve safety during recovery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
positioning procedure (lateral decubitus head-up or supine head-up)
What this could lead to
If it works, this could give doctors a simple, no-cost way to prevent oxygen drops after routine endoscopy.
What could go wrong
This is a positioning study, not a drug trial. The benefit may be small or not apply to all patients. Results are still being collected.

The number the study aims to enrol. It can still change while the study runs.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age ≥ 18 years. 2. Both sexes. 3. American Society of Anesthesiologists (ASA) physical status classification I-III. 4. Scheduled for combined painless esophagogastroduodenoscopy/colonoscopy or either of the two procedures. 5. Ability to understand the study protocol and provide written informed consent. 6. A broad set of inclusion criteria was adopted to enroll a patient population that better reflects routine clinical practice. The study aimed to enhance the generalizability of the findings by including patients with various comorbidities, such as preprocedural hypoxemia (room-air SpO₂ ≤ 90%), history of pulmonary surgery, obstructive sleep apnea (OSA), and other pulmonary conditions (including asthma, COPD, chronic bronchitis, emphysema, and pulmonary bullae). Exclusion Criteria: 1. Severe cardiovascular or cerebrovascular diseases. 2. Pregnant patients. 3. History of hypersensitivity to ciprofol. Withdrawal Criteria: 1. Endotracheal intubation required during the procedure. 2. Voluntary withdrawal requested by the patient or their legal representative.
