N-acetylcysteine (NAC) is an antioxidant administered in both oral and injectable forms.69 Recent data have shown that NAC treatment increased the level of endogenous antioxidants and diminished interleukin production in the acute phase of burn trauma.70 One potential mechanism was proposed is that NAC is an effective inhibitor of TNF-α, IL-1β, and IL-8 release in endothelial and epithelial cells.70 Animal models have shown that the administration of NAC increased glutathione and decreased MDA levels in the lung 1 hour and 1 day after burn.71 Tsai et al.69 showed that treating burns with NAC 3.0% resulted in better re-epithelialization. This is also seen with nitric oxide, which has been used in burn patients to treat hypoxic pulmonary vasoconstriction and to improve ventilation/perfusion mismatches and therefore tissue oxygenation.84. Nuclear factor κB (NF-κB), a transcription activator protein, is activated immediately following severe burn injury (SBI) and is thought to regulate the induction of several inflammatory mediators, including tumor necrosis factor (TNF-α).6 Sequestered leukocytes in injured tissues are also thought to be a major source of proinflammatory mediators that cause microvascular damage.4 The products released by tissue injury result in a biphasic response.
Original, peer-reviewed articles present the latest information on surgical procedures, acute care, … It has been demonstrated in the past that hematopoietic stem/progenitor cells, as well as pluripotent very small embryonic-like stem cells, are mobilized into peripheral blood in patients and experimental animals in response to tissue/organ injury.88 This phenomenon indicates an intrinsic mechanism involving circulating stem cells must exist to ameliorate tissue damage.88, With the ever advancing field of stem cell research and the seriousness of burn injuries, recent studies have attempted to use stem cells to improve burn injury outcomes.88,–90 Several approaches have been proposed, including coverage of damaged skin by artificial skin equivalents, topical application of expanded keratinocytes, or engraftment of bone marrow-derived cells.88.
One key fact with regard to medical management of patients being treated with high doses of vitamin C is the inaccurately high point of care glucose (POCG) readings observed.65 Kahn and Lentz65 showed that mean POCG (225 ± 71) was significantly higher than laboratory glucose (138 ± 41; P = .002).65 Inaccurate POCG could potentially lead to iatrogenic hypoglycemia and even seizures if the fictitious hyperglycemia is treated with insulin. Each model has inherent limitations in replicating the clinical situation. Cell therapy is therapeutic administration of living cells aimed at tissue regeneration, support for any defective function (such as wound healing), and modulation of pathophysiological processes (such as hyperinflammation or immune dysfunction).58 Epithelial sheets can be directly grafted on donor sites to accelerate and improve their regeneration to harvest split-thickness autografts faster and several times from the same donor site. Furthermore, epidermal burn injury often triggers significant apoptosis of organ cells, which may be caused by a severe burn-induced systemic inflammatory reaction. Review of Emergency Response Management of 33 Major Burn Victims of the Formosa Fun Coast Dust Explosion Disaster in a Regional Hospital Without Burn Units.

Multiple formulas are used but the most common is the Parkland formula, which is further discussed in the “Management” section. The second phase of a burn injury is predominantly anti-inflammatory.7 This phase depends on T lymphocytes of helper Th-2 and three principal mediators: the cytokines IL-4/IL-10 and TGF.7 This phase has become known as the counter anti-inflammatory response syndrome.7, These previously discussed inflammatory mediators along with the increase of vascular hydrostatic pressure caused by vessel dilation are the major reasons for systemic microvascular leakage observed in burns.10 As a response to inflammation, the endothelial cell junctions widen and gaps form, resulting in compromised barrier functions.11 One known mechanism behind these vascular changes involves actomyosin-dependent actin rearrangement.11 Recently, it was discovered that thermal injury induces generalized venular hyperpermeability and that serum from burned rats induces endothelial cell actin rearrangement, contraction, as well as tight junction damage.12 Studies show that exposure to burn serum results in a significant increase in endothelial permeability in a time-dependent manner, which is paralleled by a rapid and persistent activation of the p38 mitogen-activated protein kinase.13 Inhibition of p38 mitogen-activated protein kinase largely ameliorates resulting vascular dysfunction.11,13 The maintenance of normal vascular permeability depends on the integrity of endothelial barrier function regulated by the interaction of intracellular junctions, cell–matrix adhesion, and the cytoskeleton contractile force.10 Furthermore, kinins, specifically bradykinin, are produced at the burn injury site.6 Bradykinin is a powerful vasoactive mediator that causes venular dilation, increased microvascular permeability, smooth muscle contraction, and pain.6, After thermal injury, tissue adenosine triphosphate levels gradually fall, and increased adenosine monophosphate is converted to hypoxanthine, providing substrate for xanthine oxidase.14 These complex reactions lead to deleterious free radicals, such as superoxide and hydrogen peroxide.14 In addition to xanthine oxidase-related free radical generation in burn trauma, adherent-activated neutrophils produce additional free radicals.14 Free radicals have been found to have beneficial effects on antimicrobial action and wound healing. Alternatively, epithelial sheets can also be grafted alone on debrided burns, with less optimal healing quality, or in combination with a widely meshed split-thickness autografts for a better aesthetic result.58 Ultimately, the reconstruction of a complete tissue-engineered skin featuring both the epidermis and the dermis is the goal to improve healing quality and avoid scar formation.44,58 Cultured epidermal autografts have a couple major drawbacks: fragility, high cost, and poor cosmetic quality of healed zones, mostly due to their lack of underlying dermis, which results in an immature dermal–epidermal junction.48 Mesenchymal stem cells (MSCs) could provide an answer to all of these drawbacks.

[Sunflower oil is efficient for removing bitumen in asphalt burn of head and hands]. 88, – 90 Several approaches have been proposed, including coverage of damaged skin by artificial skin equivalents, topical application of expanded keratinocytes, or engraftment of bone marrow-derived cells. Management of inhalation injury consists of supportive care as no clear standard treatment has been shown to improve clinical outcomes.4 Cincinnati Shriners Hospital for children recently retrospectively examined an anti-inflammatory pulmonary enteral nutrition formula previously used in adults. Perhaps the most valuable information to date is the years of clinical experience and observations in the management and treatment of patients, which has contributed to a gradual improvement in reported outcomes of mortality. A small, retrospective, single-center study with 30 patients using historical controls and receiving the same ventilatory strategy found a 38% decrease in mortality and reduced lung injury scores when nebulized unfractionated heparin, N-acetylcysteine and albuterol sulfate were administered in comparison with albuterol.84 A pediatric case series with historical controls similarly found a significant decrease in mortality, incidence of atelectasis and reintubation rate in a group treated with an alternating regime of aerosolized heparin alternating with 20% N-acetylcysteine solution.84 Yet, a multicenter, prospective trial is still needed to confirm these data as reliable and reproducible before it can be accepted as a new standard of care.84, Another challenge with clinical trials is observed when different studies report conflicting results. Clinical observation also leads to clinical trials.
