Brief Summary

The incidence of intra operative and postoperative pain after neurosurgery is high. The pain is due to handling of the skin, subcutaneous tissue, craniotomy and dural opening. Postoperative chronic pain seriously affects patient’s quality of life.  Compound local scalp nerve block is a good choice for analgesia for this. However, the scalp nerve block commonly cannot cover the area of suboccipital retrosigmoid approach craniotomy, leading to incomplete block. Superficial cervical plexus block (SCPB) is promising to solve the analgesia requirements of such surgical approach. At the same time, ultrasound guidance can accurately locate, ensure the effect of block and avoid accidental injury during puncture.

The purpose of this study is to explore whether ultrasound-guided superficial cervical plexus block can safely and effectively reduce the incidence of pain and reduce the dependence on opioids after a neurosurgery via suboccipital retrosigmoid approach.
