Laser Therapy, Assisting

Using the highly focused and intense energy of a laser beam, the surgeon can treat various skin lesions. Laser therapy has several advantages. As a surgical instrument, the laser offers precise control. It spares normal tissue, speeds healing, and deters infection by sterilizing the operative site. The laser beam also leaves a nearly bloodless operative field because it seals tiny blood vessels as it vaporizes tissue.

Laser therapy can be performed on an outpatient basis. The lasers used most commonly to treat skin lesions are vascular, pigment, and carbon dioxide (CO2) lasers. (See Understanding types of laser therapy.)

In general, laser surgery is safe, although bleeding and scarring can result. One pronounced hazard, to the patient and treatment staff alike, is eye damage or other injury caused by unintended laser beam reflection. For this reason, anyone in the surgical suite, including the patient, must wear special goggles to filter laser light, and the surgeon must use special
nonreflective instruments. Access to the room must be strictly controlled, and all windows must be covered.

Preparation of Equipment

Perform hand hygiene 2,3,4 and gather the equipment. Prepare the tray. It should include a local anesthetic, as ordered, and dry and wet gauze. The gauze will be used to control bleeding, protect healthy tissue, and abrade and remove any eschar, which would otherwise inhibit laser absorption. Prepare nonreflective surgical instruments as needed.

Cover all the windows and door windows in the treatment room to prevent the laser from being seen through the windows, creating a potential for exposure.1

Fire is a significant hazard during laser use. Make sure that water, saline, and a fire extinguisher are readily available for use during the procedure.1
