Summary

This study looks at whether a numbing injection in the scalp, guided by ultrasound, can keep heart rate and blood pressure more stable during brain surgery and reduce pain afterward. About 72 adults having elective brain surgery will either get the scalp block or standard local numbing. Researchers will track pain scores and opioid use for 24 hours after surgery.
