Ruby Laser (694 nm) Day before Laser Treatment generate, create code39 none for java projects Web app Patients are instruct j2se bar code 39 ed to clip or shave the treatment site one day before treatment. Alternatively, shaving may be performed by the staff immediately before treatment, if the patient prefers. Hairs should be cut to around 1 mm in length to prevent hair char, which may burn the epidermis, and to eliminate the plume of smoke that may be noxious to the patient and operator.

Patients with a history of HSV infection in or near the treatment area should initiate oral antiviral medications twenty-four hours prior to the procedure.. Day of Treatment Topical anesthetic cr ANSI/AIM Code 39 for Java eam may be applied to reduce discomfort. The cream should be applied after shaving the hairs and should be removed completely prior to laser treatment. Available effective anesthetic preparations include LMX4 (4% lidocaine) and LMX5 (5% lidocaine), both manufactured by Ferndale Laboratories.

LMX should be applied thirty to sixty minutes prior to the procedure as thickly as possible, without occlusion. Alternatively, EMLA (a eutectic mixture of 2.5% lidocaine and 2.

5% prilocaine; Astra Pharmaceuticals) is applied sixty to ninety minutes prior to the procedure under plastic wrap occlusion. Since there is some absorption of topical anesthetic creams, large areas, such as the back, cannot be covered without a risk of toxic levels of absorption. There have been reported cases of death occurring from absorption of topical anesthetic cream under occlusion for laser hair removal.

Before each treatment, the risks of the procedure should be reviewed and informed consent documentation should be obtained. Preoperative photographs are helpful to assess treatment response..

TREATMENT Selection of Laser The ruby was the rst laser used for hair removal. It is most appropriate and effective for light-skinned patients (skin types I or II) with dark hairs but is also more effective than other lasers at treating lighter-colored hair. High epidermal melanin absorption at 694 nm precludes its use in tanned skin or skin type III or greater, as dose-related side effects, such as vesiculation, crusting, and pigment change, can occur.

These side effects can happen with any laser system but are more common with the ruby laser. Common pulse widths are 3 or 4 ms, and uences of greater than 40 J/cm2 are more effective than uences of less than 40 J/cm2 . Devices with integrated active cooling include the E2000 (Palomar) and the RubyStar (Aesclepion-Meditec) lasers.

The Sinon (Wavelight) laser includes cooling by forced cold air.. Alexandrite (755 nm). The lasers and light sources with proven ef cacy for permanently removing hair are the long-pulsed ruby laser (694 nm), the long-pulsed alexandrite laser (755 nm), the diode laser (800 nm), the long-pulsed Nd:YAG laser. The longer wavelength 3 of 9 barcode for Java of the alexandrite laser allows for greater depth of penetration than the ruby laser. More important, this wavelength is less well absorbed by melanin, allowing more safe and effective treatment of patients with somewhat darker skin types, although anything darker than a light type IV should probably be treated with a longerwavelength laser such as one at 1,064 nm. The same is true when any kind of tan is present in type III, and even type II, patients.

As with other wavelengths, using longer pulse durations provides more epidermal protection. Alexandrite devices now available are equipped with multiple spot sizes, variable pulse widths, and cooling devices utilizing cryogen spray or forced cold air. Using the largest spot size available generally gives the most effective treatment.

Larger spot sizes give slightly greater depth of penetration at the same uence and therefore yield safer, more effective treatment. A typical setting for types II III skin with no suntan might be 20 J/cm2 with an 18-mm spot size, 30 J/cm2 with a 15-mm spot size, and 40 J/cm2 with a 12-mm spot size, all at a 3-ms pulse duration with a cryogen cooling spray. With 755-nm alexandrite lasers, spot sizes less than 12 mm are ineffective at achieving permanent hair reduction due to scatter of the beam, resulting in failure to reach effective uences at the required depth.
