About this study

Official title: Preemptive Single Dose Tizanidine and Ultrasound Guided Superficial Cervical Block on Pain After Thyroidectomy

Thyroid surgery is a quite painful procedure performed in a sensitive skin area of the human body. Unless pain is treated adequately thyroid surgery may cause severe postoperative pain and discomfort for the patients.

a2-Agonists are sympatholytic and centrally acting antihypertensive agents. In addition to their hypotensive effect, a2-agonists are also used in anesthetic practice for their sedative and analgesic effects. Tizanidine is a centrally acting a2-agonist with muscle relaxant, sedative and anxiolytic properties. This drug is widely used for the treatment of spasticity and has recently been used to treat musculoskeletal pain conditions.

Ultrasound (US) guidance during regional anesthesia practices has been a revolutionary advancement to improve success and safety of regional anesthesia. Analgesic effect of US guidance superficial cervical plexus block (SCPB) in patients undergoing thyroid surgery has not been reported yet.

The aim of this study was to evaluate the analgesic effect of preemptive oral single dose tizanidine and US guidance SCPB in patients undergoing elective thyroid surgery. The investigators hypothesis that: Tizanidine and US guided SCPB can reduce the pain scores, analgesic consumption, analgesic related side effects.

What is being measured

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

  1. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS) score of 0-10 (0= no pain and 10= worst imaginable pain) at first hour postoperatively.

    Measured: postoperative first hour

  2. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS) score of 0-10 (0= no pain and 10= worst imaginable pain) at second hour postoperatively.

    Measured: postoperative second hour

  3. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS) score of 0-10 (0= no pain and 10= worst imaginable pain) at 4th hour postoperatively.

    Measured: postoperative 4th hour

  4. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS) score of 0-10 (0= no pain and 10= worst imaginable pain) at 8th hour postoperatively.

    Measured: postoperative 8th hour

  5. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS)score of 0-10 (0= no pain and 10= worst imaginable pain) at 12th hour postoperatively.

    Measured: postoperative 12th hour

  6. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS)score of 0-10 (0= no pain and 10= worst imaginable pain) at 24th hour postoperatively.

    Measured: postoperative 24th hour

Secondary outcomes (1)

  1. Opioid consumption

    Measured: First 24 hours total opioid consumption

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Tizanidine, Bupivacaine and Saline in people with Thyroidectomy, run by Ataturk University at 1 site in Turkey (Türkiye).

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 1 inclusion and 6 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 20 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Visual analog pain score (time frame: postoperative first hour). The study lists 6 primary outcomes in all. 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 NCT02725359, which also lists 4 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 20 Dec 2016; AzTrials last refreshed its copy on 7 Nov 2026.
