What is being measured
The primary outcome is the main question the study is designed to answer.
Analgesic effect of bilateral superficial cervical plexus block in postoperative neck surgeries
To assess the analgesic efficacy of bilateral superficial cervical plexus block on postoperative pain following neck surgery, as measured by the Visual Analog Scale Pain was assessed using the Visual Analog Scale (VAS; 0 = no pain, 10 = worst imaginable pain) at 1, 4, 8, 12, and 24 hours postoperatively.
Measured: within the first 24 hours postoperatively
Secondary outcomes (1)
Total opioid consumption
To assess the total opioid consumption within the first 24 hours postoperatively and the time to first analgesic request.
Measured: within the first 24 hours postoperatively

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing superficial cervical plexus block guided by ultrasound with bupivacaine and Paracetamol (500 mg) tablets in people with Postoperative Pain, run by Sohag University at 1 site in Egypt.
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 1 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: under way, not looking for participants, as of the sponsor's last update on 23 Apr 2026. 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 Egypt. 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?
This study is still under way. Results are not available in the source record yet.
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?
Analgesic effect of bilateral superficial cervical plexus block in postoperative neck surgeries (time frame: within the first 24 hours postoperatively). 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 23 Apr 2026.
