DESCRIPTION (provided by applicant): Each year in the United States, two million people suffer burn injuries resulting in approximately 100,000 - 300,000 hospitalizations. Of these two million, more than 12,000 will eventually die of burn-related infections. People suffering from burn wounds have lost a portion of their integument, diminishing one of the body's main defenses against bacterial infection. In addition, the necrotic tissue in the burn eschar, combined with the presence of serum proteins, provides a rich culture medium for microorganisms. Added to the loss of integument is the adverse affect of thermal injury on both local and systemic immunity. For these reasons, infections and sepsis are the most common cause of death among hospitalized burn patient. New methods of burn wound management require a cocktail of antimicrobial and antibiotic agents to fight infection however; they are becoming less effective due to resistant strains of microorganisms. In this Phase I effort we will demonstrate the feasibility of a fundamentally new method for burn wound care. The point of care (POC) system will be designed to generate sterile saline or water to moisten or wet the dressings for both the eschar as well as the graft after excision and deliver a broad based antimicrobial agent effective, against gram positive and gram-negative bacteria and fungi to the wound surface.

描述（由申请人提供）：在美国，每年有200万人遭受烧伤，导致大约100，000 - 300，000人住院。在这200万人中，超过12，000人最终将死于烧伤相关感染。遭受烧伤的人失去了一部分外皮，削弱了身体对细菌感染的主要防御之一。此外，烧伤焦痂中的坏死组织与血清蛋白的存在相结合，为微生物提供了丰富的培养基。热损伤对局部和全身免疫力的不利影响除了皮肤的损失外。由于这些原因，感染和败血症是住院烧伤患者中最常见的死亡原因。然而，烧伤伤口管理的新方法需要抗菌剂和抗生素的混合物来对抗感染;由于微生物的耐药菌株，它们变得不那么有效。在第一阶段的工作中，我们将证明一种全新的烧伤创面护理方法的可行性。护理点（POC）系统将被设计为产生无菌生理盐水或水，以在切除后润湿或润湿焦痂和移植物的敷料，并将有效对抗革兰氏阳性和革兰氏阴性细菌和真菌的广谱抗菌剂输送到伤口表面。
