Gerador de alta frequência como recurso para tratamento de úlceras por pressão: estudo piloto

High-frequency generator in the treatment of necrotizing fasciitis in a person with diabetes

Objective: A case report on the treatment of necrotizing fasciitis with the use of high frequency (HF) generator in a person with diabetes. Methods: This is descriptive study of applied nature developed in an outpatient clinic in Minas Gerais. The patient underwent dressing sessions three times a week for high frequency application. Healing was weekly evaluated using the Pressure Ulcer Scale Healing (PUSH) instrument and Image J software. Results: The area was significantly reduced, which was measured during six weekly evaluations. In the first four evaluations, a progressive reduction of the lesion was obtained in 11.78 cm², that is, 90% of the area. Conclusion: The use of the AF generator was effective in the treatment of necrotizing fasciitis, reducing the lesion area.

Gerador de alta frequência no tratamento de fasciíte necrotizante em pessoa com diabetes

Objetivo: Relato de caso sobre o tratamento da fasciíte necrotizante com a utilização do gerador de alta frequência (AF) em uma pessoa com diabetes. Métodos: Trata-se de um estudo descritivo de natureza aplicada, desenvolvido em um ambulatório no interior de Minas Gerais. A paciente foi submetida a sessões de curativo durante três vezes na semana para aplicação de alta frequência. A cicatrização foi avaliada semanalmente por meio do instrumento Pressure Ulcer Scale Healing (PUSH) e pelo software Image J. Resultados: Houve redução significativa da área da lesão, que foi mensurada durante seis avaliações semanais. Nas quatro primeiras avaliações, foi obtida redução progressiva da lesão em 11,78 cm², ou seja, 90% da área. Conclusão: O uso do gerador de AF foi efetivo no tratamento da fasciíte necrotizante, com redução da área da lesã

High-Frequency Generator in Wound Healing of Marjolin's Ulcer After Carcinoma Resection

Marjolin's ulcers (MU) are skin malignancies that form over burn injuries. These very aggressive ulcers can result in functional and wound healing impairment, and require a well thought out treatment plan. Physiotherapy offers resources to help promote recovery of these patients, as described in this case report, in which the patient with a history of burn in the lower limbs evolved to malignancy 32 years later. This patient underwent tumor resection of the left foot, with recurrence and lymphadenectomy. Physical therapy included the application of high-frequency generator (HFG) for wound healing and exercises for functional recovery. The treatment lasted for many months and resulted in the improvement of the surgical wound areas, pain, swelling, sensitivity, strength muscle, and gait. It was observed that the use of HFG can be a tool in the tissue repair of surgical wound after the resection of MU; however, further studies need to be carried out to suit parameters and ensure safety of cancer patients.

Action of AlGaInP laser and high frequency generator in cutaneous wound healing. A comparative study

PURPOSE

To evaluate in a macroscopic, histological and histomorphometric manner the healing process of cutaneous wounds in mice.

METHODS

The sample consisted of 40 male mice and was divided in four groups: 1st group (control, n=10), 2nd group (High Frequency Generator - HF, the maximum amplitude range, 120s, n=10), 3rd group (AlGaInP Laser 660 nm, 30mW power, 5 J/cm2, applying scan mode, 120s, n=10) and 4thgroup (AlGaInP Laser 660 nm, 30 mW power, 8 J/cm2, applying scan mode, n=10). The surgical incision was made with an 8 mm diameter punch perpendicularly to the back of the animal. The statistical analysis was achieved by the statistical test One Way Anova post hoc Tukey Test and significance at p<0.05 in GraphPad Prism program.

RESULTS

It was observed that in the acute phase the AlGaInP Laser at 5 J/cm2 provided a greater stimulus to healing, and both lasers were effective in the remodeling phase.

CONCLUSION

The AlGaInP lasers from 5 J/cm2 to 8 J/cm2 showed better biomodulatory results in the acute and remodeling phases respectively, however, the HF was less effective than the laser, providing significant benefits only in the acute phase of tissue repair.
