Trial summary
In the domain of endocrine gland surgery, thyroidectomy is the most common procedure. Patients report moderate to severe discomfort postoperatively, which is induced by a variety of mechanisms, the most common of which are cervical incision and surgical maneuvers. Read more about this study

About this study
Official title: Evaluation of Ropivacaine and Ropivacaine Plus Magnesium Sulphate Infiltration for Postoperative Analgesia in Patients Undergoing Thyroidectomy
In the domain of endocrine gland surgery, thyroidectomy is the most common procedure. Patients report moderate to severe discomfort postoperatively, which is induced by a variety of mechanisms, the most common of which are cervical incision and surgical maneuvers. The other two causes are endotracheal intubation and neck overextension. Incisional pain, odynophagia, dysphagia, neck and shoulder pain have all been reported as sources of discomfort.However, it seems that this discomfort has a time limit, with a considerable decrease in pain scores that will last 24 to 36 hours. Pain is felt more profoundly within the first few hours after surgery, peaking at 6 hours, with patients requesting further analgesic medication.
Surgical wound infiltration can inhibit this procedure by preventing the alginate signal from reaching the incision site's receptors. According to the multimodal analgesia trends, magnesium sulfate can be added to the ropivacaine solution. Magnesium acts as an NMDA (N-methyl-D-aspartate) receptor antagonist, inhibiting cerebral sensitization to peripheral pain stimuli while reducing pre-existing hyperalgesia.
It becomes evident that this combination could contribute to attain the maximum analgesic efficacy. So, if any superiority of ropivacaine plus magnesium sulphate over ropivacaine could be demonstrated this would be very helpful in providing sufficient analgesic effects with a low incidence of adverse effects, while enhancing the option of one day surgery.

A Phase 4 study testing Ropivacaine 10% and Ropivacaine 10% plus magnesium sulphate 10mg/kg in people with Thyroid Diseases and Parathyroid Diseases, run by Aristotle University Of Thessaloniki at 1 site in Greece.
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 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 17 Jul 2024. 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 Greece. 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?
Efficacy of Ropivacaine Plus Magnesium Sulphate Infiltration vs Ropivacaine (time frame: 24 postoperative hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 17 Jul 2024.
