Summary

Patients admitted in the Emergency Service that have pressure ulcers will be selected by eligibility criteria and randomized into three groups according to the adopted therapy: wound dressing (CG); wound dressing + high-frequency generator group (GAF); and wound dressing + low-level laser therapy group (GLBP).

Detailed description

Wound dressing is considered the standard treatment for pressure ulcers, however, despite its proven efficacy, it's a long-term healing process. Among Physiotherapy resources available for pressure ulcers treatment, the most used are low-level laser therapy and high-frequency generator. Even though the individual effects of both are evidenced on literature, there are no randomized clinical trials evidencing the effects of low-level laser therapy and high-frequency generator in comparison to wound dressing on pressure ulcers treatment.

Conditions

• Pressure Ulcer

Interventions

Type	Name	Description
DEVICE	Low-level laser therapy AlGaInP	Pressure ulcers will be treated with AlGaInP 660 nm laser, wich will be used once a day, five days per week, dosed with 6 J/cm2. Laser therapy is applied punctually in each 1cm2 of the ulcer.
DEVICE	High-frequency therapy with O3 formation	High-frequency laser therapy will be applied with spherical electrode, wich contains neon gas inside, from a short distance from the pressure ulcer. The application will last 15 minutes, with increasing intensity from 80 to 100% for ozone formation, once a day, five days per week.
OTHER	Wound dressing with saline solution	Wound dressing will be done daily on patients from the three groups during the study period. On patients who will receive laser therapy and high frequency, the pressure ulcer will be sanitized with worm saline solution in order to clean the wound. This cleaning will be done before and after the interventions.
