All lasers are equipped with an emergency shut- off button that may be depressed if the device needs to be rapidly turned off order flagyl 200 mg without a prescription. Even with protective eyewear flagyl 200 mg generic, the operator should never look directly into the laser tip while the laser is connected to a power source purchase flagyl 250 mg on-line. There are reported cases of experienced laser operators doing so using 1064 nm lasers with resultant permanent visual field deficits. Plumes of aerosolized tissue are created with ablative lasers, and tattoo lasers may splatter blood or tissue, which poses risks of airborne and contact exposure to bacteria and viruses. Cosmetic history is also reviewed including: previous aesthetic procedures and surgeries (modality, frequency, date of treatments, response, satisfaction with results, and complications). Identifying activities that can interfere with treatments is important such as routine sun exposure and water-related activities (e. It is recommended that the provider and patient simultaneously examine the desired treatment areas using a handheld mirror. Lesions indicated for treatment are identified such as lentigines, freckles, erythema, and telangiectasias as well as lesions suspicious for skin cancers, and it is documented in the chart. Lesions suspicious for melanoma or other skin cancer are biopsied or referred, and benign results confirmed prior to proceeding with laser treatments. Early on in the consultation process, it is advisable to assess whether patients will derive adequate benefit from minimally invasive treatments or require surgical intervention. Patients presenting with severe wrinkles and excessive skin laxity may not have significant improvements from minimally invasive treatments and may be better served by surgery. For patients who are candidates for minimally invasive procedures, treatment options and recommendations are reviewed including the expected degree of improvement and anticipated number of treatments. It is important to note that treatment outcomes vary from person to person and a specific percentage of improvement cannot be guaranteed for a given patient. Patients with unrealistic expectations or body dysmorphic disorder may have a history of repeated dissatisfaction with prior aesthetic treatments and these are contraindications for aesthetic procedures. The informed consent process is followed for each procedure with inclusion of a signed consent form in the chart (see Informed Consent section below). Photographic documentation of conditions and lesions indicated for treatment and results are recommended (see Photodocumentation section below). In general, individuals with more melanin in their skin have a darker baseline skin color, are more resistant to sunburn, and are classified as a high Fitzpatrick skin type. Fitzpatrick skin type may grossly predict complication risks with treatments and can be used as a guide to selecting the type of aesthetic treatment most appropriate for a patient and the aggressiveness of that treatment. It is a baseline measure performed at the time of aesthetic consultation and may also be used to grossly guide treatment selection and the aggressiveness of treatment. All aspects of the informed consent process are covered prior to performing procedures, and this consist of: (i) discussing the risks, benefits (with emphasis on realistic expectations), alternatives, and complications of the procedure; (ii) providing adequate opportunity for all questions to be asked and answered; (iii) educating the patient about the nature of their aesthetic issue and procedure details; (iv) signing the consent form; and (v) documenting the informed consent process in the chart. Photodocumentation Photographs that are used to document clinical findings and incorporated into the medical record are referred to as photodocumentation. Taking photographs is recommended prior to treatment, midway through a series of treatments, and posttreatment. Consent for photographs is typically included in the procedure consent form and obtained prior to taking photographs. Consistent lighting and positioning is important, particularly with wrinkle reduction treatments as results can be subtle and challenging to capture photographically. Photographs are taken of the full face and zoomed in to specific treatment areas from the front, 45 and 90 degrees. Selecting the Appropriate Laser Procedure for Photoaged Skin Skin rejuvenation involves optimizing treatment efficacy while minimizing recovery time and procedural risks. As a general rule, it is prudent to use the least aggressive and least painful laser initially such as nonablative lasers, and progress to more aggressive laser treatments such as ablative lasers when less invasive modalities will not achieve desired results. Treatment of photoaged skin usually requires addressing multiple issues including dyschromia, vascular ectasias, skin texture and wrinkles. Providers can approach treatment of multiple issues sequentially by addressing dyschromia and vascular ectasias first and then addressing texture and wrinkles afterward. Treating in this order is advisable as improvements in texture are more apparent once dyschromia and vascularities are improved. Another approach is to use a more aggressive laser that addresses multiple aspects of photoaging at once such as fractional ablative skin resurfacing. These lasers can treat pigmented lesions and wrinkles simultaneously but require more downtime and have more risks than nonablative lasers. Assuming a variety of laser devices are on-hand for treatment, the approach used is often determined by patient preference. Some patients prefer a less aggressive approach with a greater number of treatments, others, particularly those with advanced photoaging changes, desire the more aggressive approach. Laser Treatments in Patients with Dark Background Skin Dark background skin color is associated with increased epidermal melanin concentration. Epidermal melanin serves as a competing chromophore with cutaneous lesions for laser absorption during treatment, and can reduce treatment efficacy and increase risks of epidermal thermal injury. Complications such as postinflammatory hyperpigmentation, hypopigmentation, and burns are more likely to occur in patients with dark background skin color. Treatments in patients with dark background skin are performed using conservative laser parameters: long wavelengths (the safest of which is 1064 nm), long pulse widths, large spot sizes, and low fluences. These parameters allow for deep cutaneous penetration that decreases absorption by epidermal melanin, reducing the risk of complications. Alternative Therapies Other aesthetic procedures that treat facial lines and wrinkles include: botulinum toxin for dynamic wrinkles, nonlaser skin resurfacing procedures such as microdermabrasion and dermabrasion (rarely used today due to risks of pigmentary changes and scarring), and chemical peels for treatment of static wrinkles. Hair can be permanently removed with electrolysis, and tattoos can be minimized with topical caustic agents (also not recommended due to risks of scarring). Further discussion of alternative therapies to particular laser treatments are discussed in each chapter. Advantages of Laser Treatment Lesion specificity Short treatment times High efficacy when appropriate device is selected Disadvantages of Laser Treatment Expensive relative to most other procedures (except surgery) Risks of cutaneous thermal injury Risks of ocular injury Typically require multiple treatments, and if not, then singular aggressive treatments are associated with procedural discomfort, have longer recovery times and higher risks of complications General Laser Contraindications Active infection in the treatment area (e. Oral retinoids (isotretinoin) within the prior 6 12 months are associated with increased risks of scarring and poor healing due to impaired sebaceous gland function. Although these risks are clearly associated with ablative laser treatments, some recent studies show no adverse effects in patients undergoing nonablative laser treatments while using oral retinoids. Other conditions may also impair healing such as collagen vascular diseases, poorly controlled diabetes mellitus, and use of immunosuppressive drugs as well as prior procedures that reduce adnexal structures in the treatment area such as deep chemical peels, dermabrasion, radiation therapy, and extensive electrolysis. Patients with poorly controlled diabetes and those using immunosuppressive medications are also at increased risk of infection. IndicationsThe chapters in this book are organized by treatment indication: hair removal, pigmented lesions, vascular lesions, tattoo removal, nonablative skin resurfacing for wrinkle reduction, and ablative skin resurfacing for wrinkle reduction. Preprocedure Checklist Aesthetic consultation Fitzpatrick skin type Examination of treatment area Informed consent Pretreatment photographs Sun protection Antiviral and other pretreatment medications A preprocedure checklist is performed prior to treatment to help ensure safety and maximize results, and each chapter includes a checklist specific to that procedure. Ablative laser treatments require more advanced preprocedure planning and the preprocedure checklist is usually started 4 6 weeks prior to treatment. The checklist for laser hair removal treatments is begun 4 weeks prior to treatment to ensure patients discontinue certain methods of hair removal.
