Early Phase 1CompletedNCT02066818

East Carolina University20 enrolled

Overview

Local anesthesia used for incision and drainage of abscesses is known to be painful. We studied the analgesia provided by a lidocaine/tetracaine patch compared to injectable lidocaine during incision and drainage (I\&D) of skin abscesses. Local injection of lidocaine provided similar analgesia compared to the lidocaine/tetracaine patch during I\&D of skin abscesses in the Emergency Department. Pain at presentation and following the procedure was similar in both groups.
