Effect of Pulsed High Intensity Laser on Healing of Burn Wound: An Experimental Study

Background: wound healing is a complex biochemical and biologic process. Purpose: This study was carried out to investigate the influence of 1046-nmPulsed High Intensity Nd: YAG Laser in the treatment of 3rddegree burn wound on rats. Methods: twenty clinical healthy male Sprague-Dawley (SD) rats with induced two full thickness burn wound measuring 5 cm2on the dorsal aspect, one wound act as control and the other as study. Thecontrol wound receive standard wound care without laser and study wound received 6 weeks pulsed high intensity laser250 j/cm2 in three phases (initial, intermediate and final phase) according to designed protocol. Results: The result revealed that there was statistical significant difference in wound surface area (WSA) and percentage of healing for study wound after 1,2,3,4,5 and 6 weeksas compared to control woundConclusion: pulsed high intensity Nd: YAG laser was an effectiveand a new trend physical therapy modality in the treatment of 3rd degree burn wound.
