Efeitos da fotobiomodulação no tratamento de úlceras por pressão: Revisão integrativa

Pressure ulcers (PU) are important causes of morbidity, in addition to having a high cost to the health system, it adds an additional risk to patients because it imposes the loss of the constitutional skin barrier. Photobiomodulation with low power laser (FBM) shows effective analgesic, anti-inflammatory and tissue repair actions. The aim of the present study was to evaluate the effectiveness of FBM in the treatment of PU based on an integrative review guided by the question “How effective is photobiomodulation in the treatment of pressure ulcers?”. The study included seven articles selected from the Scielo, PubMed and LILACS databases between 2015 and 2020. After reading, analyzing and interpreting the data, it was possible to verify that, although there are few recent studies on laser therapy on the subject of pressure injury, the articles elucidate that low-level laser therapy is a promising treatment modality, which reduces the healing time and improves the appearance of wounds. However, although several studies have demonstrated its beneficial effects, there is still no consensus and specific protocols defined that determine irradiation parameters, such as wavelength, energy, fluency, power, irradiance, pulse duration and intervals between treatment sessions.
