Summary

This study looks at whether giving a scalp nerve block before a craniotomy (brain surgery) can lower pain after surgery and reduce the need for strong painkillers. Researchers will compare giving the block before the first cut versus after. The study plans to enroll 64 adults aged 18-65 who are having brain surgery under general anesthesia.
