Trial summary

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. Read more about this study

About this study

Official title: Ultrasound Guided Superficial Cervical Plexus Block for Analgesia After Craniotomy Via Suboccipital Retrosigmoid Approach: A Randomized Controlled Trial

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 block, Control group

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Superficial cervical plexus blockProcedure or surgery

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

  • Control groupOther

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the cumulative consumption of sufentanil by the PCA

    the cumulative consumption of sufentanil by the PCA 24 hours after surgery

    Measured: 24 hours after surgery

Secondary outcomes (4)
  1. Use of analgesics by the PCA after operation

    the cumulative consumption of sufentanil by PCA

    Measured: at 1, 2, 4, 48 hours after surgery.

  2. Pain severity score

    It will be accessed using NRS

    Measured: at 1, 2, 4, 24, 48 hours after surgery

  3. 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.

    Measured: at 1 hour after surgery

  4. Patient analgesic satisfaction

    Patient satisfaction with overall pain management will be evaluated at 24 hours after surgery using NRS

    Measured: at 24 hours after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Superficial cervical plexus block in people with Plexus Block;Analgesia;Neurosurgery, run by Beijing Tiantan Hospital at 2 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the cumulative consumption of sufentanil by the PCA (time frame: 24 hours after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04036812, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2025.
