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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers monitor blood flow and heart function in older adults having hip replacement under spinal anesthesia. They compare cemented and non-cemented procedures using a continuous arterial pressure monitor. The study also checks whether changes during surgery relate to heart and kidney markers afterward.

What this could mean

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

What this could lead to
If the study clarifies how bone cement affects the heart, doctors could refine monitoring and anesthesia plans for older adults having hip replacement.
What could go wrong
This small observational study cannot prove cause and effect, and its findings may not apply to other hospitals, surgical teams, or patient groups.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

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

Who is studied

The study population consists of adult patients aged 50 to 90 years who are scheduled to undergo hip arthroplasty under neuraxial anesthesia at a tertiary university hospital. Eligible patients have ASA physical status I-III, a body mass index below 30 kg/m², and planned invasive arterial blood pressure monitoring as part of routine perioperative care. Patients are allocated into cemented and non-cemented hip arthroplasty groups according to standard surgical indications. All participants provide written informed consent prior to enrollment.
