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

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 Results may not be published yet.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.

Summary

This study looked at 107 pregnant women having planned C-sections to see if belly size and internal belly pressure affect how high spinal anesthesia spreads. Researchers measured these factors before surgery and checked the numbness level after anesthesia. The goal is to better understand why spinal blocks vary among pregnant women, which could help improve anesthesia safety and effectiveness.

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 better predict how spinal anesthesia will spread in pregnant women, leading to safer and more effective C-sections.
What could go wrong
This is a small, completed observational study, not a treatment trial. The findings may not apply to all pregnant women or change current practice without further research.
