Ultrasound-guided superficial cervical plexus blocks for persistent pain after suboccipital craniotomies: a randomized trial

This is the authors' abstract. We don't add key points for this paper.

The efficacy of superficial cervical plexus blocks for reducing persistent pain after craniotomies remains unclear. We therefore tested the primary hypothesis that preoperative ultrasound-guided superficial cervical plexus blocks reduce persistent pain 3 months after suboccipital craniotomies.
