Fototerapia (LEDs 660/890nm) no tratamento de úlceras de perna em pacientes diabéticos: Estudo de caso

Abstract

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% 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, respectively. Phototherapy accelerated wound healing of leg ulcers in diabetic patients. ©2009 by Anais Brasileiros de Dermatologia.
