Low Level Laser Therapy and Phototherapy Assisted Hydrogel Dressing in Burn Wound Healing: Light Guided Epithelial Stem Cell Biomodulation

Abstract

As a result of the influence of fetal wound healing, recent trends in wound dressing have been toward a focus on the wet condition. The other current focus is on energy transmission for wounds such as electromagnetic energy and negative pressure therapy to the wound for the purpose of rapid healing. In many countries basic hydrogel dressing material is used such as Comfeel gel (Coloplast, Denmark) with foam or Opsite (Smith and Nephew), etc. Therefore wound dressing transillumination is performed by a combination of transparent dressing, low level laser, LED light source (Omnilux PDT lamp, FDA approved NASA space LED for wound healing) and polarized light (Bioptron, FDA approved) [1, 2, 8]. For the treatment of various wounds including burns and pressure sores, laser assisted aquaphoresis and several other techniques such as modulation of granulation tissue, epithelialization and wound contraction are used. Low level laser therapy (LLLT) (Cho Yang, Korean Medical Laser Laboratory — Kim’s Mochida Diode and Erchonia, FDA approved Lasers) and phototherapy for early skin rehabilitation are very useful for functional recovery as well as for cosmetic skin problems such as erythema, hyperpigmentation, psoriasis, keloid and hypertrophic scar formation.
