Summary

This study looked at whether giving a light electrical pulse to a specific spot on the wrist (called P6) during breast cancer surgery could help prevent nausea and vomiting after the operation. 188 women at high risk for post-operative nausea took part. The goal was to see if adding this simple, non-drug method to standard anti-nausea medicine works better than medicine alone.
