Effect of SPG Block for Patients With Anxiety at Electronic Dance Music Festivals
Stopped: No research capacity to support the project at this time.
Canada0Started 2026-05-06
Plain-language summary
The goal of this clinical trial is to learn about the effect of a sphenopalatine ganglion (SPG) block in anxious patients at electronic dance music festivals. The main question is:
\- Is an SPG block useful in reducing anxiety, in comparison to placebo?
Participants will have lidocaine-soaked cotton tip applicator placed inside each nare for 10-minutes, or have a saline-soaked cotton tip applicator placed inside each nare for 10-minutes.
Researchers compare the lidocaine-soaked intervention (SPG block) with the saline-soaked intervention (placebo) to see if it reduces anxiety in patients presenting at electronic dance music festivals with anxiety.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Festival attendees aged 18+
* A complaint of anxiety of at least 1 on a scale of 0 to 10 (11-point scale, where 0 represents "no anxiety" and 10 represents "worst anxiety imaginable").
Exclusion Criteria:
* Known allergy to lidocaine (standard practice involves medical team members asking patients what allergies they have; we will not directly ask about lidocaine in order to keep participants blinded to interventions)
* Inability to insert cotton tip applicator through the nares (e.g., distorted nasal anatomy, active nosebleed, obstructed nasal passages)
* Inability to verbally report level of anxiety
* Prior administration of an oral or intravenous anti-anxiety medication (e.g., lorazepam, midazolam) by festival medical staff since arrival at the festival (would confound treatment effect)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
