What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

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.

Summary

This study watches brain oxygen levels and anesthesia depth in 75 adults during a procedure to fix a brain aneurysm. The goal is to see how these measurements relate to each other and to vital signs like blood pressure. No extra treatments are given—just careful observation to help doctors better understand what happens in the brain during surgery.

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 diagnosed with intracranial (cerebral) aneurysm who are scheduled to undergo endovascular coil embolization under general anesthesia. Participants will be monitored intraoperatively using near-infrared spectroscopy (NIRS) and bispectral index (BIS) as part of standard anesthetic care. The study population represents a real-world cohort of patients undergoing elective neurointerventional procedures.

Ages

18 to 75 years

Sex

Anyone

Healthy volunteers

Not accepted

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