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 Results may not be published yet.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.

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 tested whether a passive leg raising test, done before spinal anesthesia, can predict low blood pressure in women having planned C-sections. Researchers measured heart function with ultrasound before and after raising the legs. They then tracked blood pressure drops and the need for medication during surgery. The goal was to see if this simple test could identify women at higher risk.

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 successful, this could help doctors predict and prevent dangerous drops in blood pressure during C-sections, making the procedure safer.
What could go wrong
This is a small, completed observational study with only 64 participants. The test may not be accurate enough for routine use, and results may not apply to all patients.

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