Effect of SPG Block for Patients With Anxiety at Electronic Dance Music Festivals

• Status: Not yet recruiting
• Trial end date: 2024-07-01
• Target enrollment: 0
• Participant gender: All

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)
