Carbon Dioxide Laser - Treatment using CO2 Laser Surgery
Indications: Warts, cavernous haemangiomas, chronic lupus, erythematosus, seborrhoeic warts, keratoses
Carbon Dioxide Laser is a convenient method of superficial destruction. CO2 snow is prepared by letting out CO2 liquid gas from cylinders, through a small jet, into a chamois leather bag. As the liquid gas comes out, snow forms.
The snow is put into metal moulds to give it a special shape which is ordinarily like a pencil. This pencil is held in several layers of gauze and applied to the selected lesion. Firm pressure is maintained; the period of application varies from 30 seconds to 2 minutes (usually 1 minute in most cases) depending upon the amount of destruction desired. The healthy skin surrounding the lesion should be well protected from the destructive effects of CO2snow. The destroyed lesion forms a crust surrounded by erythema and oedema; this takes from one to two weeks to subside.
Mixed with acetone and sulphur, CO2 snow has been used in the form of slush for the treatment of acne scarring. With a brush or a wooden applicator it is painted on the affected area. With the introduction of liquid N2, CO2 snow has fallen into disfavor.
