In this work, we analyze the clinical alterations and histological modifications in patients with not infect ulcers of pressure, submitted to the Laser irradiation GaAs (wavelength 904 nm, doses 3 J/cm², during 1 minute and prompt application) during 5 days consecutive and as a group radiated during 15 days alternating. In the clinical evaluation after the laser irradiation observed presence of exudation, granulation tissue and points of bleed after the third day of irradiation. The computerized morph quantitative analysis demonstrated that submitted to the laser irradiation during the 15 days busy area for the 4115,922 vases was of µm², and in the radiated ones during 5 4348,253 days of µm², both in a 0,25 area of cm² of derma. The gotten results suggest that this therapeutically one was efficient as to assist in the processes of tissue regeneration in the patients treated in the research. Neste trabalho, analisamos as alterações clínicas e modificações histológicas em pacientes com úlceras de pressão não infectadas, submetidos à irradiação Laser AsGa (comprimento de onda 904 nm, dose 3 J/cm², durante 1 minuto e aplicação pontual) durante 5 dias consecutivos e um segundo grupo irradiado durante 15 dias alternados. Na avaliação clínica após a irradiação laser observou-se presença de exsudação, tecido de granulação e pontos de sangramento após o terceiro dia de irradiação. A análise morfológica e quantitativa computadorizada demonstrou que os submetidos à irradiação laser durante 15 dias a área ocupada pelos vasos foi de 4115922 µm², e nos irradiados durante 5 dias de 4348253 µm², ambos em uma área de 0,25 cm² de derme. Os resultados obtidos sugerem que esta terapêutica foi eficaz como auxiliar nos processos de regeneração tecidual nos pacientes tratados na pesquisa
