![]() ![]() The skin is moist, pink or red, and is perfused, as demonstrated by blanching on pressure. Due to the exposure of sensory nerve endings in the superficial dermis, these wounds are often painful and tender. Superficial partial-thickness burns are caused by exposure to heat sufficient to cause damage to the epidermis and papillary dermis of the skin. However, the depth of burn is not always static because of the various factors (e.g., inadequate tissue perfusion resulting from the injury), which may release a cascade of vaso-active and inflammatory mediators and, in turn, deepen the burn wound. Also, there are few wound dressing products that differ from each other in only one feature (e.g., presence or absence of chlorhexidine) and few studies that were designed to assess the efficacy of one single characteristic of a wound dressing.īurns are classified by depth into superficial (involving epidermis only) partial-thickness (superficial, mid and deep partial-thickness), involving part of the dermis and full-thickness burns, in which all of the dermis is destroyed, and which may extend to involve subcutaneous tissue, muscular, neurovascular, or skeletal structures. There is a lack of evidence for the comparison of individual dressing options with placebo or no treatment because the basic principles of burn wound management preclude the option of no dressing treatment for all but the most minor of burns. Reviewing the current evidence systematically can be challenging in this area due to a lack of clarity and consistency in the terminology used in studies concerning type of burn and difficulty in consistent classification of the various individual dressings. Adverse events are relatively rare, which means that trials require large numbers of recruits. In part, this is due to the difficulty of objectively assessing wound depth at the time of injury and also to the logistics of determining wound healing times. There is a lack of evidence regarding best dressings as treatments for partial-thickness burn injuries. ![]()
