Local Anesthetic Response in Ehlers-Danlos Syndrome (EDS) and Healthy Volunteers
Local anesthetic resistance is commonly reported by patients with EDS. However, there are no objective data on the occurrence of local anesthetic resistance in EDS patients and in healthy volunteers. We propose to collect such objective data on the frequency of drug resistance and whether any problems with local anesthesia are due to initial ineffectiveness or due to its effects dissipating too soon.
