What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Sphenopalatine Ganglion BlockProcedure or surgery
Sphenopalatine Ganglion Block will be performed by a transnasal approach. Few drops of lidocaine 2% will be instilled into both anterior nares. Then a cotton-tipped applicator soaked in 4% lignocaine \& adrenaline (1 to 200000 will be passed through both the nares and the end of the applicator tip will be positioned just superior to the middle turbinate and anterior to the pterygopalatine fossa and sphenopalatine ganglion for 5 min with the patient in the supine position.
Medical TreatmentDrug
Patients will receive paracetamol 1 gm 6 hours daily intravenously for a day. If adequate pain relief will not be achieved, intravenous diclofenac 75 mg twice daily will be added.
| Study group | Role | What they receive |
|---|---|---|
| Standard medical Treatment (paracetamol) | Active comparator | Patients will receive paracetamol 1 gm every 6 hours daily intravenously for a day. Receives: Drug: Medical Treatment |
| Sphenopalatine block | Experimental | Patients will receive sphenopalatine block Receives: Procedure: Sphenopalatine Ganglion Block |

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Sphenopalatine Ganglion Block and Medical Treatment in people with Sphenopalatine Ganglion Block and Adrenaline, run by Tanta University.
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: status not confirmed, as of the sponsor's last update on 8 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. 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?
Results are not available in the source record.
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 analgesia demonstrated by visual analogue scale (VAS) less than 4 (effective) in the first 48 hours (time frame: 48 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 8 Dec 2020; AzTrials last refreshed its copy on 8 Nov 2026.
