ABSTRACT

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 CSE–FMRP–USP, 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 (LED’s) associada à SDZ acelerou processo de cicatrização das UVCs (G1/G2), comparada ao creme isoladamente (G3), pelos ICUs e pela relação E/G.


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 –FMRP–USP, 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 SDZ’s 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.

ABSTRACT

Avaliou-se a fototerapia na cicatrização de úlceras de perna (UP) mistas em dois pacientes diabéticos (tipo 2), hipertensos. O aparelho apresentava sonda 1 (S1) (1 LED de 660nm, 5mW) aplicado em 3 UP e sonda 2 (S2) (32 LEDs de 890nm e 4 LEDs de 660nm, 500mW) em 6 UP. Após antissepsia,úlceras foram tratadas com sondas a 3J/cm2, 30seg, 2x/semana seguido pelo curativo diário com sulfadiazina de prata a 1 por cento por 12 semanas. Pela análise com software Image J®, as UP com S2 tiveram índices de cicatrização médios de 0,6; 0,7 e 0,9 enquanto S1 foi de 0,2; 0,4 e 0,6 no 30º, 60º e 90º dias, respectivamente. A fototerapia acelerou a cicatrização das úlceras de perna em pacientes diabéticos.


This study evaluated the use of phototherapy in the healing of mixed leg ulcers in two diabetic patients (type 2) with arterial hypertension. The device had probe 1 (one 660nm LED, 5mW) applied in 3 ulcers and probe 2 (32 890nm LEDs associated with 4 660nm LEDs, 500mW) in 6 ulcers. After asepsis, ulcers were treated with probes to 3 J/cm2, 30sec per point, twice a week, followed by topical daily dressing with 1 percent silver sulphadiazine during 12 weeks. The following analyses of ulcers with software Image J showed that probe 2 presented mean healing rates of 0.6; 0.7 and 0.9, whereas probe 1 had 0.2;0.4 and 0.6 at 30, 60 and 90 days, espectively. Phototherapy accelerated wound healing of leg ulcers in diabetic patients.
