Summary

The incidence of postoperative chronic pain after craniotomy is high. Postoperative chronic pain seriously affects patient's quality of life. Compound local scalp nerve block is a good choice for analgesia after craniotomy. 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 theoretically promising to solve the analgesia requirements of such surgical approach. At the same time, ultrasound guidance can not only 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 chronic pain after craniotomy via suboccipital retrosigmoid approach.

Conditions

• Neurosurgery

Interventions

Type	Name	Description
PROCEDURE	Superficial cervical plexus block	Ultrasound guidance will be used to determine the location of superficial cervical plexus nerve. The puncture will also be performed by ultrasound guidance, covered with opaque infusion dressing but performed with infusion of 10 ml 0.5% ropinacaine.
OTHER	Control group	Ultrasound guidance will be used to determine the location of superficial cervical plexus nerve. The puncture will also be performed by ultrasound guidance, covered with opaque infusion dressing but performed with infusion of 10 ml normal saline.
