Awards & highlights


This trial will measure the frequency of local anesthetic resistance in EDS patients and healthy volunteers to understand if EDS contributes to it.

Who is the study for?
This trial is for individuals with genetically confirmed non-hypermobile Ehlers-Danlos Syndrome (EDS), those clinically diagnosed with hypermobile EDS, and healthy volunteers without EDS. Participants must be able to give informed consent. Those allergic to Lidocaine cannot join.Check my eligibility
What is being tested?
The study aims to objectively measure local anesthetic resistance in people with EDS compared to healthy individuals by using a common saltwater solution (0.9% Sodium Chloride) as a control and Lidocaine Injection 2% as the test intervention.See study design
What are the potential side effects?
While the saltwater injection should have no side effects, Lidocaine may cause reactions at the injection site, numbness beyond the target area, dizziness, or rarely more serious effects like allergic reactions.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Local anesthetics, commonly used in nerve blockades, function by blocking sodium channels in nerve cells, which prevents the initiation and transmission of nerve impulses, thereby providing pain relief. This mechanism is particularly significant for Ehlers-Danlos Syndrome (EDS) patients, who often experience chronic pain due to joint instability and frequent injuries. However, EDS patients frequently report resistance to local anesthetics, which can complicate pain management. Understanding this resistance is crucial for developing effective pain management strategies, ensuring that EDS patients receive adequate and sustained relief from their symptoms.
