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.
