Summary

This study will observe 100 adults having gallbladder surgery to see if their pre-surgery anxiety and pain from getting an IV can predict how much pain they feel after the operation. Researchers will measure anxiety with a questionnaire and IV pain with a 0-10 scale, then track pain and painkiller use for 12 hours after surgery. The goal is to find simple ways to identify who might need extra pain relief.

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 it works, this could help doctors personalize pain management after surgery based on simple pre-op tests.
What could go wrong
This is a small observational study, not a treatment trial. It may not find a strong link, and results may not apply to other surgeries or patients.
