Comparing how long local anesthetics last in dermatologic surgery

Characterizing and Comparing the Duration of Local Anesthetic in Dermatologic Surgery - Fourth Arm

Phase 4 Interventional Weill Medical College of Cornell University · NCT06694714

This study is testing whether using different amounts of a local anesthetic during skin surgery affects how long the numbness lasts, especially in areas with lots of blood vessels.

What this trial studies

This study investigates the duration of action of local anesthetics used in dermatologic surgery, specifically focusing on how the volume of anesthetic affects its effectiveness at highly vascular sites. The researchers will compare two different volumes of lidocaine with epinephrine injected at the nasal ala and assess the duration of anesthesia using a non-invasive pinprick testing method. The goal is to determine if varying volumes of the same anesthetic lead to significant differences in duration of action, considering the vascularity of the injection site.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with normal skin sensation at the nasal ala who can provide informed consent.

Not a fit: Patients with a history of adverse reactions to local anesthetics or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could optimize the use of local anesthetics, leading to improved pain management during dermatologic procedures.

How similar studies have performed: Previous studies have explored similar methodologies, but this specific investigation into the effects of anesthetic volume at vascular sites is novel.
