RESUMO
Introdução:
Várias são as propostas terapêuticas para úlceras de perna venosas crônicas (UVCs), como curativos, ultrassom, aparelhos fotobioestimuladores (laser/LED) e outros.Objetivo:
Analisar a eficácia da fototerapia (LED 660/890 nm) com curativo diário de sulfadiazina de prata 1 por cento creme (SDZ) para úlceras venosas crônicas.Métodos:
Estudo randomizado, duplo-cego, com aparelho fototerápico com 2 sondas 1 (LED 660 nm/5mW) e 2 (1 LED 660 nm e 32 LED 890 nm/500 mW). Selecionaram-se 20 pacientes (n = 32 úlceras) do Ambulatório de Úlceras CSEFMRPUSP, constituindo-se grupos G1-sonda 1+SDZ; G2-sonda 2+SDZ e G3-SDZ, seguidos por 90 dias. Aplicaram-se sobre as úlceras, as sondas pontualmente (3,0 J/cm2, 30 seg/5cm2, 2x/semana) e posterior curativo SDZ. Quinzenalmente, foram fotografadas e avaliadas pelo software Image Jâ, mensurando-se as áreas [total, de esfacelo (E); e de tecido de granulação (G)], calculando-se índices de cicatrização das úlceras [ICU = (Ai-Af)/Ai)] e relação E/G.Resultados:
G2 apresentou redução significante no 30º e 90º dia (p 0,4, G2 alcançou este índice em 75 por cento das úlceras no 30º e 90º dias, enquanto 33 por cento do G1, somente no 60º.Conclusão:
A fototerapia (LEDs) associada à SDZ acelerou processo de cicatrização das UVCs (G1/G2), comparada ao creme isoladamente (G3), pelos ICUs e pela relação E/G.ABSTRACT
Introduction:
Many therapeutic forms were used to treat chronic venous ulcers such as dressing, ultrasound, photobiostimulator (laser/LED) and other.Objective:
To analyze effectiveness of phototherapy (LED 660/890 nm) with 1 percent silver sulfadiazine cream (SDZ) in chronic venous ulcers.Method:
Randomized and double-blind study using the phototherapy device with 2 probes 1 (LED 660 nm/5mW) and 2 (1 LED 660 nm and 32 LED 890 nm, 500 mW). Twenty patients were selected (n = 32 ulcers) from Ulcer Outpatient Clinic of the School Health Center FMRPUSP, divided into groups G1-probe1+SDZ, G2-probe2+SDZ and G3-SDZ, during 90 days. The probes were applied on ulcers, punctually (3 J/cm2, 30 sec/5cm2, twice/week) and posterior daily SDZs dressing. Fortnightly, the ulcers were photographed and evaluated by Image J® software, measuring the areas [total, sphacellus (S) and granulation tissue(G)], calculating wound healing rate [WHR = (iA-fA)/iA)] and S/G relation.Results:
G2 presented significant reduction in the 30th and 90th days (p 0.4, G2 achieved this rate in 75 percent of the ulcers in the 30th and 90th days, while 33 percent of the G1 only in the 60th days.Conclusion:
The phototherapy (LED) associated with SDZ accelerated wound healing of the venous ulcers (G1/G2) compared the cream (G3) by WHRs and S/G relation.
