Could a simple scalp injection replace opioids after brain surgery?

This trial tests whether adding ultrasound-guided scalp blocks—local anesthetic injections around the scalp—to standard anesthesia can reduce severe pain after planned brain surgery. Up to 30% of patients experience moderate to severe pain after such procedures, and current painkillers often rely heavily on opioids. The study will compare the need for morphine and pain scores in the first six hours after surgery between patients receiving the blocks and those receiving standard care alone.
