Summary

This study compares two types of ultrasound-guided nerve blocks for controlling pain after mastectomy: the standard paravertebral block and a newer proximal intercostal block. Researchers want to see if the newer block offers better needle visibility, faster procedure time, and improved safety. The study involves 20 women scheduled for mastectomy.

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 nerve block (proximal intercostal block or paravertebral block)
What this could lead to: If successful, this could show that the proximal intercostal block is a safer, easier-to-perform option for controlling pain after mastectomy.
What could go wrong: This is a very small, early-stage study with only 20 participants, so results may not apply to all patients or settings. The study focuses on imaging quality and procedure time, not long-term pain relief.
