Periprocedural Care

Patient Preparation


Injectable lidocaine is administered before most destruction techniques. Lidocaine plus epinephrine prolongs the anesthetic effect and further reduces blood loss.

An alternative for small lesions is to use a eutectic mixture of local anesthetics (EMLA) cream, which contains 2.5% lidocaine and 2.5% prilocaine. EMLA cream under occlusion should be applied to the skin at least one hour before the procedure to achieve topical anesthesia.

In patients who are allergic to "caine," diphenhydramine (25 mg/mL) solution is diluted in 1-5 mL of sterile normal saline and injected intradermally. This is effective for most small skin lesions.


Monitoring & Follow-up

Gentle daily washing of the wound with mild soap and water is recommended. The wound may be left exposed to air or covered with a light bandage for comfort.

Larger-area wounds that require more prolonged healing by secondary intention may benefit from application of a topical antibiotic such as neomycin or mupirocin to prevent infection.

Careful chart notes regarding the location of the lesion allow for periodic re-examination of the area to observe for signs of any recurrence.
