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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests whether keeping elderly patients on their side for 15 minutes after spinal anesthesia, instead of lying on their back, can prevent blood pressure drops. Researchers will enroll 70 high-risk patients aged 65 and older having leg surgery. The approach aims to keep the anesthetic concentrated on the surgical side, potentially reducing side effects.

What this could mean

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

Active substance
lateral decubitus positioning
What this could lead to
If it works, this simple positioning change could help prevent dangerous blood pressure drops during spinal anesthesia in elderly patients.
What could go wrong
This is a small early-stage trial with only 70 patients, so results may not apply to everyone. The benefit may be small or not occur at all.
