RESUMEN
Objective To explore the clinical effect of moist dressing combined with high energy narrow band phototherapy on chronic dermal ulcer.Methods Sixty cases with dermal chronic ulcer were randomly divided into two groups equally.The experimental group was treated by moist dressing combined with high energy narrow band phototherapy,while the control group was treated by moist dressing.The areas of wound surface were compared after treating for 14 and 21 days.Result Twenty-one days after treatment,the areas of wound surface were significantly reduced in the experimental group than that in the control group(P<0.05).Conclusion Moist dressing combined with high energy narrow band phototherapy can eradicate necrotic tissue,adjust micro-environment,and promote granulation and healing in chronic dermal ulcer.
