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.

Criteria
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)
