Evaluation of the Effects of Low Level Laser Therapy on the Healing Process After Skin Graft Surgery in Burned Patients (A Randomized Clinical Trial)

Abstract

Introduction: Skin graft is the standard therapeutic technique in patients with deep ulcers, but like every surgical procedure, it may present some complications. Although several modern dressings are available to enhance comfort of donor site, the use of techniques that accelerate wound healing may enhance patient’s satisfaction. Low level laser therapy (LLLT) has been used in several medical fields, especially for wound healing, but it may take several months for large ulcers treated with laser to heal completely

Methods: Nine patients with bilateral similar grade 3 burn ulcers in both hands or both feet were selected as candidates for split-thickness skin graft (STSG). One side was selected for laser irradiation and the other side as control, randomly. Laser was irradiated every day for 7 days with red 655 nm light, 150 mW, 2 J/cm2 at the bed of the ulcer and with infra-red 808 nm light, 200 mW for the margins

Results: The rate of wound dehiscence after skin graft surgery was significantly lower in laser treated group in comparison to control group which received only classic dressing P=0.019

Conclusion: The results showed LLLT to be a safe effective method which improves graft survival and wound healing process and decreases the rate of wound dehiscence in patients with deep burn ulcers
