Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.

Summary

This study looks at whether a patient's body measurements can predict how easy or difficult it is to perform an interscalene block, a type of nerve block used for shoulder surgery. Researchers will measure factors like neck size and shape to see if they affect block success, procedure time, and ultrasound image quality. The goal is to help doctors plan better and improve patient safety.

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 which patients may have a more difficult block, improving planning and safety.
What could go wrong
This is a small observational study, so results may not apply to all patients or settings. It does not test a new treatment.

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