Ignition potential of the 585-nm pulsed-dye laser. Review of the literature and safety recommendations.

BACKGROUND

The 585-nm pulsed-dye laser is the treatment of choice for many port-wine stains. The risk of accidental flash fires occurring with the pulsed-dye laser is considered minimal. Recently, however, there have been several reports of unwanted ignitions. These cases all share two features: 1) oxygen delivery by face mask, and 2) the ignition of a hair-bearing surface.

OBJECTIVE

We report a case of a laser-induced fire that occurred on a non-hair-bearing surface in a patient who was receiving oxygen by nasal cannula. The mechanisms, risk factors, and guidelines for the prevention of pulsed-dye laser-induced fires are presented.

METHODS

We reviewed the literature regarding the safety of pulsed-dye laser use.

RESULTS

Pulsed-dye laser-induced fires can occur on non-hair-bearing regions and in patients receiving oxygen by nasal cannula.

CONCLUSION

Precautions should be taken to prevent pulsed-dye laser fires regardless of treated region or method of oxygen delivery.
