Abstract
to compare the effect of adjuvant low-laser light therapy versus conventional treatment alone on venous ulcer healing. this is a randomized clinical trial with 40 patients randomized equally to a control group (topical and compressive treatment) and intervention group (adjuvant low-laser light therapy). Outcomes of interest were Wound Healing: Secondary Intention and Tissue Integrity: Skin & Mucous Membranes, as described in the Classification of Nursing Outcomes/NOC. groups with similar sociodemographic and clinical characteristics. Eighty-two ulcers were assessed, with an average duration of 1 to 5 years, in 1,066 nursing consultations, with a statistically significant difference in the time and number of healed ulcers (intervention group). There was a significant improvement in the nursing outcomes under study and in eight clinical indicators. low-laser light therapy improves and reduces tissue regeneration time, contributing to advances in wound treatment.
Highlights
Venous ulcer (VU) is a type of chronic leg wound that affects 0.5 to 2.2% of the adult population and 3 to 5% of those over 65 years old[1]
Forty patients participated in the study, 20 of which were allocated to the IG and 20 to the CG
The present study showed that this process can be improved by adjuvant Low-laser light therapy (LLLT) which, when combined with conventional treatment, produces superior wound healing results and, improves patient comfort
Summary
Venous ulcer (VU) is a type of chronic leg wound that affects 0.5 to 2.2% of the adult population and 3 to 5% of those over 65 years old[1]. 93% of VUs heal within 12 months, but the remaining 7% persist for 5 years or more. The proper treatment of these ulcers is a search for the ideal healing process, and must take into account the different phases of these highly contaminated and proteolytic wounds as well as the various therapeutic modalities available[3]. In many cases, conventional treatment fails to produce good results, and new approaches are needed. Low-laser light therapy (LLLT), which promotes photochemical effects on irradiated tissues, has emerged as an alternative for wound treatment[4]. LLLT is nonionizing, collimable, polarized, monochromatic, coherent light and can modify cell behavior to facilitate tissue repair. This, in turn, stimulates the irradiated cells, which can multiply, regenerate or secrete any mediators needed to achieve homeostasis[5,6,7,8]
