Associations Between Diode Laser (810 nm) Therapy and Chronic Wound Healing and Pain Relief Wound Repair and Regeneration

TAKE-HOME MESSAGE

• This retrospective cohort study evaluated the effects of diode laser irradiation on pain and healing of chronic wounds. The time to wound healing was significantly shorter in the diode laser treatment group. Patients in the diode laser treatment group also experienced an improvement in the pain relief index. The proposed mechanism includes the diode laser's thermal effect (promoting metabolism and increasing local blood flow) and biological stimulation effect (reducing inflammatory response).
• Diode laser (810 nm) therapy may help improve wound healing and pain in patients with chronic wounds.

Abstract 

Chronic wounds have become one of the major issues in medicine today, the treatments for which include dressing changes, negative pressure wound therapy, hyperbaric oxygen, light irradiation, surgery and so forth. Nevertheless, the application of diode lasers in chronic wounds has rarely been reported. This retrospective cohort study aimed to evaluate the therapeutic effect of diode laser (810 nm) irradiation on chronic wounds. Eighty-nine patients were enrolled in the study. The control group (41 patients) received traditional dressing change therapy, while the diode laser treatment group (48 patients) were patients received additional treatment with diode laser (810 nm) irradiation for 10 min at each dressing change. Wound healing time was compared between two groups, while the pain relief index was creatively introduced to evaluate the effect of relieving wound pain, which was calculated by the difference in pain scores between the first and last dressing changes divided by the number of treatment days. The wound healing time of the diode laser treatment group was 22.71 ± 8.99 days, which was significantly shorter than that of the control group (37.44 ± 23.42 days). The pain relief index of the diode laser treatment group was 0.081 ± 0.055, which was significantly increased compared with that of the control group (0.057 ± 0.033). Our findings suggest that diode laser irradiation has the potential to promote healing in chronic wounds and relieve wound pain.
