Wound Surface Area and Colony Count of Various Modes of Phototherapy

Background: The degree of tissue damage caused by related inflammatory and immunological sequelae poses a major therapeutic treatment problem in burn wounds. Chronic wounds frequently have a significant bioburden and pathogens that are resistant to antibiotics. This review article discusses present research on phototherapy, which is believed to be useful in managing wound bioburden and promoting healing. Objective: To evaluate the wound healing efficacy of polarized light therapy (BLT) against low-level laser therapy (Ga-As laser) in order to determine which is more efficient and successful at speeding burn healing. Subject and methods: The current study enrolled thirty patients having partial thickness thermal burn on the forearm (dermal burn). They were selected from Burn Unit at Legislation Association Hospital for Burns & Oncology. They were randomly assigned into two equal groups: Group (A) that included fifteen patients who received the BLT with mean age of 28.8 ± 2.51 years old and group (B) that enrolled fifteen patients who received LLLT with mean age of 29.6 ± 2.79 years old. Both groups also received traditional physical therapy and conservative treatment for the burn site three times weekly for four weeks. Results: Group A and B showed a significant reduction in colony count and wound surface area after treatment in comparison to that before treatment (p > 0.001). In group A, the colony count and wound surface area decreased by 38.63% and 55.1% respectively, but in group B, by 15.6% and 37.92% respectively. Conclusion: Both polarized light therapy and low-level laser therapy had a therapeutic efficiency on wound healing, but BLT is more efficient and more successful in the acceleration of the burned wounds healing.
