A comparative analysis of ChatGPT, ChatGPT-4 and Google Bard performances at the Advanced Burn Life Support Exam.

Artificial intelligence and Large Language Models (LLM) have recently gained attention as promising tools in various healthcare domains, offering potential benefits in clinical decision-making, medical education and research. The Advanced Burn Life Support (ABLS) program is a didactic initiative endorsed by the American Burn Association, aiming to provide knowledge on the immediate care of the severely burn patient. The aim of the study was to compare the performance of three LLMs (ChatGPT-3.5, ChatGPT-4 and Google Bard) on the ABLS exam. The ABLS exam consists of 50 questions with 5 multiple choice answers. The passing threshold is 80% of correct answers. The three LLMs were queried with the 50 questions included in the latest version of the ABLS exam, on July 18th, 2023. ChatGPT-3.5 scored 86% (43 out of 50), ChatGPT-4 scored 90% (45 out of 50), and Bard scored 70% (35 out of 50). No difference was measured between ChatGPT-3.5 and ChatGPT-4 (p=0.538) and between ChatGPT-3.5 and Bard (p=0.054), despite the borderline p-value. ChatGPT-4 performed significantly better than Bard (p=0.012). Out of the 50 questions, 78% (n=39) were direct questions, while 12% (n=11) were presented as clinical scenarios. No difference in the rate of wrong answers was found based on the type of question for the three LLMs. ChatGPT-3.5 and ChatGPT-4 demonstrated high accuracy at the ABLS exam, and outperformed Google Bard. However, the potential multiple applications of LLMs in emergency burn and trauma care necessitate appropriate surveillance and most likely should represent a tool to complement human cognition.

Surgical Excision of Burn Wounds.

Burn injuries affect patients of all ages, and timely surgical debridement and excision commence to protect dermal vascularity and integrity, improve healing, and minimize scarring. Several tools may be used for burn wound excision, which is performed either tangentially or down to muscular fascia. Once wounds are optimized from a tissue viability and healing standpoint, coverage may be obtained through grafts or secondary intention healing for more superficial injuries. A collaborative team of plastic and general surgeons, anesthesiologists, nutritionists, and therapists can provide improved patient care throughout the perioperative period, leading to improvements in overall patient morbidity and mortality.

Prevention and Management of Wound Infections in Burn Patients.

The leading cause of morbidity in burn patients is infection with pneumonia, urinary tract infection, cellulitis, and wound infection being the most common cause. High mortality is due to the immunocompromised status of patients and abundance of multidrug-resistant organisms in burn units. Despite the criteria set forth by American Association of Burn, the diagnosis and treatment of burn infections are not always straightforward. Topical antimicrobials, isolation, hygiene, and personal protective equipment are common preventive measures. Additionally medical and nutritional optimization of the patients is crucial to reverse the immunocompromised status triggered by burn injury.

Challenges in the Management of Large Burns.

Large burns provoke profound pathophysiological changes. Survival rates of patients with large burns have improved significantly with the advancement of critical care and adaptation of early excision protocols. Nevertheless, care of large burn wounds remains challenging secondary to limited donor sites, prolonged time to wound closure, and immunosuppression. The development of skin substitutes and new grafting techniques decreased time to wound closure. Individually, these methods have limited success, but a combination of them may yield more successful outcomes. Early identification of patients with likely poor prognosis should prompt goals of care discussion and involvement of a palliative care team when possible.

Free Flap Failure and Complications in Acute Burns: A Systematic Review and Meta-analysis.

Background: Severe acute burn injuries represent a challenge to the reconstructive surgeon. Free flap reconstruction might be required in cases of significant critical structure exposure and soft tissue deficits, when local options are unavailable. This study aimed to determine the free flap complication rate in acute burn patients. Methods: A systematic review and meta-analysis were conducted and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines and registered on the International Prospective Register of Systematic Reviews database (CRD42023404478). The following databases were accessed: Embase, PubMed, Web of Science, and Cochrane Library. The primary outcome was the free flap failure rate. Results: The study identified 31 articles for inclusion. A total of 427 patients (83.3% men, 16.7% women) accounting for 454 free flaps were included. The mean patient age was 36.21 [95% confidence interval (CI), 31.25-41.16]. Total free flap loss rate was 9.91% [95% CI, 7.48%-13.02%], and partial flap loss was 4.76% [95% CI, 2.66%-8.39%]. The rate of venous thrombosis was 6.41% [95% CI, 3.90%-10.36%] and arterial thrombosis was 5.08% [95% CI, 3.09%-8.26%]. Acute return to the operating room occurred in 20.63% [16.33%-25.71%] of cases. Stratified by body region, free flaps in the lower extremity had a failure rate of 8.33% [95% CI, 4.39%-15.24%], whereas in the upper extremity, the failure rate was 6.74% [95% CI, 3.95%-11.25%]. Conclusion: This study highlights the high risk of free flap complications and failure in acute burn patients.

Soluble chitosan derivative treats wound infections and promotes wound healing in a novel MRSA-infected porcine partial-thickness burn wound model.

Burns are physically debilitating and potentially fatal injuries. The most common etiology of burn wound infections in the US is methicillin-resistant Staphylococcus aureus (MRSA), which is particularly recalcitrant when biofilms form. The current standard of care, silver sulfadiazine (SSD) is effective in reducing bacterial load, but less effective in improving burn wound healing. New treatments that can manage infection while simultaneously improving healing would provide a benefit in the treatment of burns. Porcine models are frequently used as a model for human wound healing but can be expensive due to the need to separate wounds to avoid cross contamination. The porcine model developed in this study offers the capability to study multiple partial thickness burn wound (PTBW) sites on a single animal with minimal crosstalk to study wound healing, infection, and inflammation. The current study evaluates a wound rinse and a wound gel formulated with a non-toxic, polycationic chitosan derivative that is hypothesized to manage infection while also promoting healing, providing a potential alternate to SSD. Studies in vitro and in this PTBW porcine model compare treatment with the chitosan derivative formulations to SSD. The wound rinse and wound gel are observed to disrupt mature MRSA biofilms in vitro and reduce the MRSA load in vivo when compared to that of the standard of care. In vivo data further show increased re-epithelialization and faster healing in burns treated with wound rinse/gel as compared to SSD. Taken together, the data demonstrate the potential of the wound rinse/gel to significantly enhance healing, promote re-epithelialization, and reduce bacterial burden in infected PTBW using an economical porcine model.

Interdisciplinary Representation of Burn Surgery Journal and Society Leadership.

Burn care is a complex craft that requires an interdisciplinary approach. It includes a diverse array of specialty providers to provide holistic, specialized care to burn victims. This study aims to evaluate the diverse array of subspecialties involved in burn surgery journal and society leadership. A cross-sectional study was conducted in July 2019 by examining the characteristics of society and journal leaders. Current governance and committee members of the American Burn Association (ABA) and International Society of Burn Injuries (ISBI) were determined, as well as the editors of five major burn journals. Information gathered included occupation, advanced degrees obtained, and type of residency training. Of 384 editorial board members identified, 76% were physicians (n = 291), with specialties including burn surgery (n = 208, 54%) and anesthesiology (n = 22, 6%). Among nonphysicians (n = 78, 20%), 76% were medical researchers (n = 59), 8% physical therapists (n = 6), and 5% nurses (n = 4). Looking at ABA and ISBI governance (n = 29), 82% were physicians (n = 24). Nonphysician ABA and ISBI leaders were nurses (n = 2, 7%) and occupational therapists (n = 2, 7%). Of 467 identified ABA and ISBI committee members, half were physicians (n = 244, 52%). There was a wide array of nonphysician occupations among committee members, from nurses (n = 99, 21%), to occupational therapists (n = 25, 5%), and even firefighters (n = 6, 1%). Burn surgery journal and society leadership reflect the interdisciplinary nature of burn care by including an array of subspecialties. Yet, physicians tend to dominate academic burn leadership in comparison to other disciplines, highlighting the need for more nonphysician representation in leadership positions.

A Systematic Review on Airbag-Induced Burns.

Airbags significantly reduce fatalities and injuries in automobile crashes, but they have been found to be associated with burns. Specifically, airbags can cause burns through thermal or chemical mechanisms and commonly affect the arms, hands, face, and eyes. While most airbag-induced burns are minor, some may cause unfavorable outcomes. Our study aimed to systematically review airbag-induced burns to assess etiology, type, and treatment of these injuries. A systematic review of case reports pertaining to airbag-induced cutaneous and ocular burns was conducted. Data reviewed included type/location of burns, severity of burn, total number of patients, treatment, complications, and outcome after treatment. We identified 21 case reports that met our inclusion criteria with a total of 24 patients reported in the studies. Of the studies identified, 38% were chemical burns and 25% were thermal burns. Most commonly the upper extremities were burned in 42% of cases, followed by eyes (25%) and face (21%). Most burns identified were superficial partial thickness (58%). Treatment outcomes were good for cutaneous burns, with 95% healing without complication. However, ocular injuries lead to permanent impaired eye function in 71% of cases. In our systematic review, we highlighted the common risk factors, prognosis, and treatment for thermal, chemical, and ocular burns. Airbag-induced burns have a relatively good prognosis but must be recognized and treated immediately to reduce the risk of serious sequelae.

Racial and Ethnic Disparities Among Burn Surgery Leadership.

The underrepresentation of racial and ethnic minority groups has been well-documented in general and plastic surgery but not in burn surgery. The aim of this study is to evaluate current minority group disparities among burn surgery leadership. A cross-sectional analysis was performed. Burn surgeons included directors of American Burn Association-verified burn centers in the United States, past and current presidents of the American Burn Association, and editorial board members of five major burn journals (Journal of Burn Care & Research, Burns, Burns & Trauma, Annals of Burns & Fire Disasters, and the International Journal of Burns and Trauma). Surgeons were compared based on factors including age, gender, training, academic rank, and Hirsch index (h-index). Among 71 burn center directors, 50 societal presidents, and 197 journal editors, minority groups represented 18.3, 2.0, and 34.5%, respectively. Among burn center directors, the group classified collectively as nonwhite was significantly younger (49 vs 56; P < .01), graduated more recently (2003 vs 1996; P < .01), and had a lower h-index (9.5 vs 17.4; P < .05). There were no significant differences in gender, type of residency training, advanced degrees obtained, fellowships, academic rank, and academic leadership positions between white and nonwhite groups. When compared with the 2018 U.S. National Census, burn unit directors had a 5.1% decrease in nonwhite representation. Disparities in representation of ethnic and racial minorities exist in burn surgery despite having similar qualifying factors.

Gender Disparities Among Burn Surgery Leadership.

Gender disparities have been described in the plastic surgery and general surgery literature, but no data have been reported in burn surgery. The aim of this study is to determine gender disparities among burn surgery leadership. A cross-sectional study was performed. Burn surgeons included were directors of American Burn Association (ABA)-verified burn centers, past presidents of the ABA, and International Society for Burn Injuries (ISBI), and editors of the Journal of Burn Care & Research, Burns, Burns & Trauma, Annals of Burns & Fire Disasters, and the International Journal of Burns and Trauma. Training, age, H-index, and academic level and leadership position were compared among surgeons identified. Among the 69 ABA and ISBI past presidents, 203 burn journals' editorial board members, and 71 burn unit directors, females represented only 2.9%, 10.5%, and 17%, respectively. Among burn unit directors, females completed fellowship training more recently than males (female = 2006, male = 1999, P < .02), have lower H-indexes (female = 8.6, male = 17.3, P = .03), and are less represented as full professors (female = 8.3%, male = 42.4%, P = .026). There were no differences in age, residency, research fellowship, or number of fellowships. Gender disparities exist in burn surgery and are highlighted at the leadership level, even though female surgeons have a similar age, residency training, and other background factors. However, gender diversity in burn surgery may improve as females in junior faculty positions advance in their careers.

Dermatome-Induced Lacerations: An Unspoken Problem in Burn Surgery.

BACKGROUND: Dermatome-induced lacerations are a known complication; however, there is a paucity of literature discussing the incidence and predisposing factors. The aim of this study was to determine the incidence and risk factors to develop a preventive algorithm. METHODS: An 18-question survey was sent to all US and Canadian burn unit directors. Surgeons were queried about type and location of their practices, average annual caseload of skin graft harvesting, and number of dermatome-induced lacerations. The survey also asked about donor site location, harvesting technique and equipment, laceration severity, and causative factors. An algorithm was developed based on the results. RESULTS: Fifty-six responses (42% response rate) were received from the burn unit directors. They reported an estimated 133 lacerations over the past 5 y. The overall incidence of dermatome-induced lacerations was approximately 0.1% per year (1.3 per 1000 cases). The most commonly attributed causes were excessive pressure (25.0%) and patient factors (18.4%). Most lacerations occurred when using air dermatomes (73.0%) with a 4-inch guard (63.5%), 0.010- to 0.015-inch thickness (78.4%), and 30°-45° angulation (47.3%); the most common brand was Zimmer (71.6%). The dermatome was typically set up by a scrub tech or nurse (48.6%), whereas the skin harvesting was performed by residents (39.2%) or attendings (35.1%). Lacerations typically extended to subcutaneous tissue (70.3%), with no neurovascular injury (86.5%). CONCLUSIONS: Our study showed that dermatome-induced lacerations are rare events and that certain factors predispose patients to injury. An algorithm was developed to provide guidance on risk factor identification and the set up and use of dermatomes.

Isolation and Characterization of a Human Fetal Mesenchymal Stem Cell Population: Exploring the Potential for Cell Banking in Wound Healing Therapies.

Various cell-based therapies are in development to address chronic and acute skin wound healing, for example for burns and trauma patients. An off-the-shelf source of allogeneic dermal cells could be beneficial for innovative therapies accelerating the healing in extensive wounds where the availability of a patient's own cells is limited. Human fetal-derived dermal fibroblasts (hFDFs) show high in vitro division rates, exhibit low immunological rejection properties, and present scarless wound healing in the fetus, and previous studies on human fetal tissue-derived cell therapies have shown promising results on tissue repair. However, little is known about cell lineage stability and cell differentiation during the cell expansion process, required for any potential therapeutic use. We describe an isolation method, characterize a population, and investigate its potential for cell banking and thus suitability as a potential product for cell grafting therapies. Our results show hFDFs and a bone marrow-derived mesenchymal stem cell (BM-MSC) line shared identification markers and in vitro multilineage differentiation potential into osteogenic, chondrogenic, and adipogenic lineages. The hFDF population exhibited similar cell characteristics as BM-MSCs while producing lower pro-inflammatory cytokine IL-6 levels and higher levels of the wound healing factor hepatocyte growth factor. We demonstrate in vitro differentiation of hFDFs, which may be a problem in maintaining long-term lineage stability, potentially limiting their use for cell banking and therapy development.

A Qualitative Survey Study of United States Burn Units: Pathways to a Career in Burn Surgery.

With current changes in training requirements, it is important to understand the venues in the United States for a general surgery (GS) and plastic surgery (PS) resident interested in pursuing a burn surgery career. The study aims to evaluate the pathways to a career in burn surgery and the current state of leadership. A cross-sectional study was conducted between August and September 2017. A 12-question survey was sent to all burn unit directors in the United States, asking about their background, who manages various aspects of burn care and the hiring requirements. Responses were received from 55 burn unit directors (47% response rate). Burn units are lead most commonly by physicians who received GS training (69%), but the majority either did not undergo fellowship training (31%) or completed a burn surgery fellowship (29%). While surgical care (GS = 51%, PS = 42%) and wound care (GS = 51%, PS = 42%) were predominantly managed by GS- or PS-trained burn teams, management of other aspects of burn care varied depending on the institution, demonstrating that a shift in burn care management. The desired hiring characteristics, including GS (67%) or PS residency (44%) and a burn surgery (55%), trauma surgery (15%), or critical care (44%) fellowship. Directors' training significantly influenced their preferences for hiring requirements. While leadership in burn surgery is dominated by GS-trained physicians, the surgical and wound care responsibilities are shared among PS and GS. Although one third of current directors did not undergo fellowship training, aspiring surgeons are advised to obtain a burn surgery and/or critical care fellowship.

Cell-spray auto-grafting technology for deep partial-thickness burns: Problems and solutions during clinical implementation.

Cell-spray autografting is an innovative early treatment option for deep partial-thickness burn wounds. As an alternative to non-operative management, cell-spray autografting can achieve rapid wound re-epithelialization, particularly in large wounds. When compared to traditional mesh autografting for deep partial-thickness burn wounds, cell-spray autografting can accomplish re-epithelialization with a much smaller donor site. In this review, we describe the development of a biomedical engineering method for isolation and immediate distribution of autologous, non-cultured, adult epidermis-, and adult dermis-derived stem cells. We present data on cell isolation procedures in 44 patients with deep partial-thickness burns performed over five years under an innovative practice IRB. Treated patients presented with a variety of burn wound etiologies and a wide range of TBSA. Overall clinical results were very satisfying. The average hospital length of stay following treatment was seven days. Over the time period, the donor-site to burn-wound surface area ratio was enhanced from 1:80 to 1:100. A detailed analysis of all process-related biotechnology and operative problems, pitfalls, and solutions was performed and is reported herein. Strategies for future clinical studies are discussed.

Calculations for reproducible autologous skin cell-spray grafting.

Non-cultured, autologous cell-spray grafting is an alternative to mesh grafting for larger partial- and deep partial-thickness burn wounds. The treatment uses a suspension of isolated cells, from a patient's donor site skin tissue, and cell-spray deposition onto the wound that facilitates re-epithelialization. Existing protocols for therapeutic autologous skin cell isolation and cell-spray grafting have defined the donor site area to treatment area ratio of 1:80, substantially exceeding the coverage of conventional mesh grafting. However, ratios of 1:100 are possible by maximizing the wound treatment area with harvested cells from a given donor site skin tissue according to a given burn area. Although cell isolation methods are very well described in the literature, a rational approach addressing critical aspects of these techniques are of interest in planning clinical study protocols. We considered in an experimental study the cell yield as a function of the donor site skin tissue, the cell density for spray grafting, the liquid spray volume, the sprayed distribution area, and the percentage of surface coverage. The experimental data was then used for the development of constants and mathematical equations to give a rationale for the cell isolation and cell-spray grafting processes and in planning for clinical studies.

Second-degree burns with six etiologies treated with autologous noncultured cell-spray grafting.

Partial and deep partial-thickness burn wounds present a difficult diagnosis and prognosis that makes the planning for a conservative treatment versus mesh grafting problematic. A non-invasive treatment strategy avoiding mesh grafting is often chosen by practitioners based on their clinical and empirical evidence. However, a delayed re-epithelialization after conservative treatment may extend the patient's hospitalization period, increase the risk of infection, and lead to poor functional and aesthetic outcome. Early spray grafting, using non-cultured autologous cells, is under discussion for partial and deep partial-thickness wounds to accelerate the re-epithelialization process, reducing the healing time in the hospital, and minimizing complications. To address planning for future clinical studies on this technology, suitable indications will be interesting. We present case information on severe second-degree injuries after gas, chemical, electrical, gasoline, hot water, and tar scalding burns showing one patient per indication. The treatment results with autologous non-cultured cells, support rapid, uncomplicated re-epithelialization with aesthetically and functionally satisfying outcomes. Hospital stays averaged 7.6±1.6 days. Early autologous cell-spray grafting does not preclude or prevent simultaneous or subsequent traditional mesh autografting when indicated on defined areas of full-thickness injury.

Effects of wound dressings on cultured primary keratinocytes.

Autologous cell-spray grafting of non-cultured epidermal cells is an innovative approach for the treatment of severe second-degree burns. After treatment, wounds are covered with dressings that are widely used in wound care management; however, little is known about the effects of wound dressings on individually isolated cells. The sprayed cells have to actively attach, spread, proliferate, and migrate in the wound for successful re-epithelialization, during the healing process. It is expected that exposure to wound dressing material might interfere with cell survival, attachment, and expansion. Two experiments were performed to determine whether some dressing materials have a negative impact during the early phases of wound healing. In one experiment, freshly isolated cells were seeded and cultured for one week in combination with eight different wound dressings used during burn care. Cells, which were seeded and cultured with samples of Adaptic(®), Xeroform(®), EZ Derm(®), and Mepilex(®) did not attach, nor did they survive during the first week. Mepitel(®), N-Terface(®), Polyskin(®), and Biobrane(®) dressing samples had no negative effect on cell attachment and cell growth when compared to the controls. In a second experiment, the same dressings were exposed to pre-cultured cells in order to exclude the effects of attachment and spreading. The results confirm the above findings. This study could be of interest for establishing skin cell grafting therapies in burn medicine and also for wound care in general.

In vitro keratinocyte expansion for cell transplantation therapy is associated with differentiation and loss of basal layer derived progenitor population.

An alternative approach for traditional clinical mesh grafting in burn wound treatment is the use of expanded autologous keratinocytes in suspension or sheets that are cultured over 2-4 weeks in a remote service facility. While a wound reepithelialization has been described, the functional and aesthetic outcome is under debate. Cell isolation from split-skin donor tissue aims to preserve the valuable stem cell progenitors from the basal epidermal layer and to provide patients with a rapid wound reepithelialization and a satisfying outcome. While the presence of epidermal progenitors in the cell graft is thought to enable an improved epidermal surface post reepithelialization, we investigated a feasible clinical approach involving cultured versus noncultured epidermal cells comparing the α6int(high)/K15(high)/FSC(low)/SSC(low) and α6int(high)/K5(high)/FSC(low)/SSC(low) keratinocyte progenitor subpopulations before and after in vitro culture process. Our results show a significant increase of cell size during in vitro passaging and a decrease of progenitor markers linked to a gradual differentiation. A provision of the regenerative epidermal progenitors, isolated from the split-skin biopsy and applied directly onto the wound in an on-site setting of isolation and cell spray grafting in the operation room, could be of interest when choosing options for skin wound care with autologous cells.

Characterization of sex dimorphism following severe thermal injury.

Sex-based outcome differences have been previously studied after thermal injury, with a higher risk of mortality being demonstrated in women. This is opposite to what has been found after traumatic injury. Little is known about the mechanisms and time course of these sex outcome differences after burn injury. A secondary analysis was performed using data from a prospective observational study designed to characterize the genetic and inflammatory response after significant thermal injury (2003-2010). Clinical outcomes were compared across sex (female vs male), and the independent risks associated with sex were determined using logistic regression analysis after controlling for important confounders. Stratified analysis across age and burn severity was performed, whereas Cox hazard survival curves were constructed to determine the time course of any sex differences found. During the time period of the study, 548 patients met inclusion criteria for the cohort study. Men and women were found to be similar in age, TBSA%, inhalation injury, and Acute Physiology and Chronic Health score. Regression analysis revealed that female sex was independently associated with over a 2-fold higher mortality after controlling for important confounders (odds ratio, 2.2; P = .049; 95% confidence interval, 1.01-4.8). The higher independent mortality risk for women was exaggerated and remained significant only in pediatric patients and demonstrated a dose-response relationship with increasing burn size (%TBSA). Survival analysis demonstrated early separation of female and male curves, and a greater independent risk of multiple organ failure was demonstrated in the pediatric cohort. The current results suggest that sex-based outcome differences may be different after thermal injury compared with traumatic injury and that the sex dimorphism may be exaggerated in patients with higher burn size and in those in the pediatric age group, with female sex being associated with poor outcome. These sex-based mortality differences occur early and may be a result of a higher risk of organ failure and early differences in the inflammatory response after burn injury. Further investigation is required to thoroughly characterize the mechanisms responsible for these divergent outcomes.

Risk factors for hypothermia in EMS-treated burn patients.

OBJECTIVE: Hypothermia has been associated with increased mortality in burn patients. We sought to characterize the body temperature of burn patients transported directly to a burn center by emergency medical services (EMS) personnel and identify the factors independently associated with hypothermia. METHODS: We utilized prospective data collected by a statewide trauma registry to carry out a nested case-control study of burn patients transported by EMS directly to an accredited burn center between 2000 and 2011. Temperature at hospital admission ≤36.5°C was defined as hypothermia. We utilized registry data abstracted from prehospital care reports and hospital records in building a multivariable regression model to identify the factors associated with hypothermia. RESULTS: Forty-two percent of the sample was hypothermic. Burns of 20-39% total body surface area (TBSA) (OR 1.44; 1.17-1.79) and ≥40% TBSA (OR 2.39; 1.57-3.64) were associated with hypothermia. Hypothermia was also associated with age > 60 (OR 1.50; 1.30-1.74), polytrauma (OR 1.58; 1.19-2.09), prehospital Glasgow Coma Scale <8 (OR 2.01; 1.46-2.78), and extrication (OR 1.49; 1.30-1.71). Hypothermia was also more common in the winter months (OR 1.54; 1.33-1.79) and less prevalent in patients weighing over 90 kg (OR 0.63; 0.46-0.88). CONCLUSIONS: A substantial proportion of burn patients demonstrate hypothermia at hospital arrival. Risk factors for hypothermia are readily identifiable by prehospital providers. Maintenance of normothermia should be stressed during prehospital care.
