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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This trial tests whether using ultrasound to guide spinal anesthesia is better than the traditional palpation-based method in elderly patients undergoing hip fracture surgery. Participants are randomly assigned to receive either the ultrasound-guided midline approach or the conventional landmark paramedian technique. The study measures the number of needle passes, insertion attempts, and success rates to see which method is more accurate and efficient.

What this could mean

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

Active substance
Ultrasound-guided midline technique compared to conventional landmark paramedian technique for continuous spinal anesthesia
What this could lead to
If ultrasound guidance proves superior, it could become the standard for spinal anesthesia in elderly patients, making the procedure safer and more comfortable.
What could go wrong
The trial is relatively small and early-stage, and results may not apply to all patients or settings. Ultrasound requires training and equipment, which could limit widespread use.
