The incidence of postoperative pain after craniotomy is high. Severe postoperative pain can lead to a series of complications that are detrimental to the recovery of craniotomy patients. 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 requirement of analgesic drugs and pain after craniotomy via suboccipital retrosigmoid approach.

superficial cervical plexus nerve block will be performed under the guidance of ultrasound
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.

the cumulative consumption of sufentanil by the PCA
the cumulative consumption of sufentanil by the PCA 24 hours after surgery
Time frame: 24 hours after surgery
Use of analgesics by the PCA after operation
the cumulative consumption of sufentanil by PCA
Time frame: at 1, 2, 4, 48 hours after surgery.
Pain severity score
It will be accessed using NRS
Time frame: at 1, 2, 4, 24, 48 hours after surgery
Anesthesia recovery quality score：
It will be accessed at postoperative 1 and 2 hours using the Anesthesia Steward Emergence Scale. The Anesthesia Steward Emergence Scale(0-6) is divided into three parts: the degree of wakefulness - 2 points for complete recovery, 1 point for response to stimulation, 0 point for no response to stimulation; the degree of airway patency - 2 points for cough according to the doctor's order, 1 point for maintenance of airway patency without support, 0 point for support required for respiratory tract; 2 points for conscious activities of limbs with limb mobility, 1 point for unconscious activities of limbs, point for no activities of limbs.
Time frame: at 1 hour after surgery
Patient analgesic satisfaction
Patient satisfaction with overall pain management will be evaluated at 24 hours after surgery using NRS
Time frame: at 24 hours after surgery
