Effect of pulsed high intensity Nd:YAG laser on healing of experimental burn wound
نویسنده
چکیده
Wound healing is a complex and long lasting biochemical and biologic process. This study was conducted to investigate the influence of 1046-nm Pulsed High Intensity Nd: YAG Laser in the treatment of 3 rd degree experimental burn wound on rats. Twenty four clinical healthy male Sprague-Dawley (SD) rats with induced two full thickness burn wound measuring 6 cm 2 on the dorsal aspect, one wound act as control and the other as study. The control wound receive only standard wound care without laser and the study wound received 8 weeks pulsed high intensity laser 350 J/cm 2 in three phases (initial, intermediate and final phase) according to designed protocol. The result revealed that there was statistical significant difference in wound surface area (WSA) and percentage of healing (%) for study wound after 2,4,6 and 8 weeks as compared to control wound. In conclusion pulsed high intensity Nd: YAG laser was an effective, non invasive and a new trend physical therapy modality in the healing of 3 rd
