What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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 Results may not be published yet.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 observational study looks at whether a quick, non-invasive breathing score (the ROX index) can predict low oxygen levels right after nose or sinus surgery. Researchers will follow 80 adults having elective septorhinoplasty or endoscopic sinus surgery. The goal is to see if the ROX index, measured before surgery, can identify patients at risk for early postoperative hypoxemia.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients aged 18 to 65 years with American Society of Anesthesiologists (ASA) physical status I-II who are scheduled for elective septorhinoplasty or endoscopic sinus surgery under general anesthesia will be included in this study. All participants will undergo standard preoperative assessment, including measurement of oxygen saturation and respiratory rate on room air, and will be monitored postoperatively in the post-anesthesia care unit (PACU) according to routine clinical practice.

Ages
