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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares a non-invasive continuous blood pressure monitor (ClearSight) to the standard arterial catheter in 50 adults undergoing coil embolization for unruptured brain aneurysms. The goal is to see if the non-invasive method can safely detect blood pressure changes and reduce the need for invasive catheters. Participants are randomly assigned to one of the two monitoring methods during their procedure.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 50 people

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

Started

Jan 2026

Expected to finish

Aug 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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: * Adult patients (≥19 and ≤80 years old) scheduled for elective coil embolization of unruptured intracranial aneurysms under general anesthesia. * American Society of Anesthesiologists (ASA) physical status classification I-III. Exclusion Criteria: * Patients who do not provide informed consent. * Patients unable to understand or follow study instructions due to physical or mental limitations. * Patients in whom radial arterial catheterization is not feasible (e.g., peripheral vascular disease, skin disorders at the insertion site, absence of radial/ulnar artery, or orthopedic conditions of the upper extremity). * Patients with peripheral vascular circulatory disorders. * Patients with morbid obesity (BMI ≥ 40 kg/m²) \[Eley et al., 2021\]. * Patients who are hemodynamically unstable preoperatively or expected to be unstable during the perioperative period.
