Photobiomodulation used in the Post Operative in Diabetic Feet Injuries

Introduction: Diabetes Mellitus (DM) is a disease of high glucose level known for several complications. Unstable degrees of resistance and difficulty of insulin flow, deficiency of hormone response in peripheral tissues, difficult scarring and bacterial control are common complications in the diabetic foot. One of the treatments that have scientific evidence to aid in the healing process and the antibacterial effect is biophotomodulation through a LASER (Light Amplification by Stimulated Emission of Radiation) 660 nm and LED (Light Emitting Diode) 470 nm. Materials and methods: This was a quasi-experimental study in which the sample consisted of 9 patients, totaling 11 diabetic feet with ulcerations and/or amputations, mean age of 64.2 years and divided into three groups: Group 1 (LASER/LED), Group 2 (LASER) and Group 3 (LED), evaluated through Visual Analogue Scale (VAS) for pain, cirtometry for edema evaluation, contracture evaluation of the treated area through photo before and last session, with an average of seven sessions three times a week. Results: Group 1 showed increased granulation tissue, epithelial tissue, greater retraction of the ulceration area, hydrated borders without hyperkeratosis, being superior to isolated therapies. Final considerations: The application of LASER reconciled with the LED was promising and presented superior results to the isolated applications of LASER and LED. It is necessary to continue the study in a larger number of patients to obtain greater conclusive results. It is hoped that this treatment will be added to conventional treatment, providing a better quality of life for individuals suffering from diabetic feet, thus avoiding further amputations.
