Abstract
Sulfur mustard burns are characterized by delayed symptoms, slow healing, and recurrence after closure. Incomplete debridement at the level of the basement membrane is the postulated cause. Graham pioneered laser debridement of mustard burns. For field or mass-casualty use, saline wet-to-wet or antibiotic-soak debridement is more practical. In this study, we compared laser, saline, and antibiotic debridement in a porcine model of deep partial-thickness injury. Deep-dermal sulfur mustard burns were produced in 18 anesthetized Gottingen minipigs using 10-μl saturated vapor cap exposure time of 90 minutes. Debridement was started 48 hours postinjury and consisted of a single laser treatment; 5 days of 5% aqueous mafenide acetate wet-to-wet dressings; or 7 to 12 days of saline wet-to-wet dressings. Wounds were treated with daily silver sulfadiazine for 30 days and, then, assessed by histopathology, silver-ion analysis, colorimetry, and evaporimetry. All wounds healed well with no sign of infection. Antibiotic debridement showed no advantage over saline debridement. There were no significant differences between groups for colorimetry or evaporimetry. Histopathology was graded on a mustard-specific scale of 1 to 15 where higher values indicate better healing. Mean histology scores were 13.6 for laser, 13.9 for mafenide, and 14.3 for saline. Saline debridement statistically outperformed laser (P < .05) but required the longest debridement time. Laser debridement had the benefit of requiring a single treatment rather than daily dressing changes, significantly decreasing need for wound care and personnel resources. Development of a ruggedized laser for field use is a countermeasures priority.

Safety evaluation of silver-ion dressings in a porcine model of deep dermal wounds: A GLP study. Toxicol Lett 2019; 319:111-118. [PMID: 31715245 DOI: 10.1016/j.toxlet.2019.10.023] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2019] [Revised: 10/23/2019] [Accepted: 10/27/2019] [Indexed: 11/25/2022]
Abstract
INTRODUCTION Silver ion has strong antimicrobial properties and is used in a number of wound dressings. In burn models, silver-nylon dressings produce elevated silver levels in the wound along with minimal systemic effect. We evaluated systemic toxicity in a non-burn wound model to see if a similar pattern of silver ion distribution would occur. METHODS Eight deep partial-thickness wounds each were created on the dorsum of 40 Gottingen minipigs using a Er-YAG Laser. Half were treated with a 21-day course of silver-nylon dressings (Silverlon®) and half were treated with moist gauze dressings. Wound, blood, liver and kidney silver levels, along with blood chemistry and hematology data were obtained at appropriate intervals. RESULTS All wounds healed well with healing enhanced by silver-nylon dressings. Silver ion was demonstrable in all wounds treated with silver-nylon at day 21 and after 14 days of no further treatment. Silver ion was not detected in blood, liver or kidney of any animal treated with silver-nylon or control dressings. Liver and kidney function remained normal in all animals. CONCLUSION A 21-day application of silver-nylon dressings to a non-burn dermal wound produces no systemic or local toxicity in Gottingen minipigs.

Abstract
Medical support of military operations involves treatment of massive soft tissue wounds, thermal burns, open fractures, blast injuries and traumatic amputations under conditions that are often austere and far from supply lines. Military hospitals, as recently deployed in Iraq and Afghanistan, are designed and equipped for stabilization and rapid transfer of injured patients back to their home nation. These austere facilities are often tasked with the emergency or long-term treatment of local populations when injured or burned, further stressing the medical resupply system. Pathogens encountered in contemporary wartime practice are increasingly resistant to antibiotics. Ionic silver is bactericidal against a broad spectrum of bacteria, yeasts and fungi, has been utilized as a topical antiseptic for over 100 years, and has no known clinically-relevant resistance. Silver-nylon dressings, initially stocked in US military hospitals as a burn dressing, are now finding utility as a universal dressing for all types of combat wounds. Compared to conventional burn dressings, they are easier to transport and store, easier to use, and do not need to be changed as frequently, allowing for conservation of nursing resources. In this literature review, the recent military uses of silver-nylon dressings are examined. The stockpiling and use of silver-nylon as a universal military burn and wound dressing is advocated.

Abstract
Silver is a naturally occurring element. Similar to other metals, the ionized form of silver (Ag(+1)) has known antimicrobial properties. A number of wound dressings incorporating silver ion or silver compounds have recently been developed and marketed. In addition, the antimicrobial effects of silver are currently being promoted in consumer products such as clothing and household appliances. The present use of silver in medical and consumer products has prompted concerns for potential toxicity and ecological effects, including induction of microbial resistance to antibiotics. These concerns ignore the fact that silver has been used for medicinal purposes for several thousand years. A historical review of the uses of silver in medicine is presented.

Abstract
High-frequency percussive ventilation (HFPV) has been used for the management of patients with smoke inhalation injury for more than 20 years and is considered a standard of care at many burn centers. Because the ventilator is powered by air and oxygen rather than electricity, prehospital use has been limited by large-volume medical gas requirements. Since 2003, Operations Iraqi Freedom and Enduring Freedom have created a need for long-range aeromedical transfer of service members with severe burn and inhalation injuries. Unique to these conflicts is the availability of US Air Force C-17 cargo aircraft as the primary long-distance airframe. Because C-17 aircraft have a built-in medical oxygen supply, transcontinental patient transport using HFPV has become feasible. In this study, the authors report their initial experiences with the aeromedical transportation of 33 burn patients over a combined distance of 174,145 air miles using HFPV. HFPV is safe and efficacious for transcontinental flight when used by an experienced medical transport team.

Abstract
In many hospitals, intensive care units (ICUs) operate at or above capacity on a daily basis. Multiple casualty incidents will create a sudden need for additional ICU beds and hospital planning for disaster response must anticipate the need for rapid ICU expansion. In this article, the authors describe the management of 6 patients who were burned in Guam and successfully transported a distance of 7,268 miles to San Antonio, TX, for tertiary burn center care. The mission required creation of a temporary burn ICU at Tripler Army Medical Center in Hawaii, approximately midway between the referring hospital and the receiving burn center. A method of creating a temporary burn center is described. Lessons learned, including the need to standardize equipment, and to cross-train and cross-credential medical personnel, are applicable to both military and civilian mass casualty management.

Abstract
The global war on terror has created the need for urgent long-range aeromedical transport of severely wounded service members over distances of several thousand miles from Afghanistan or Iraq to the United States. This need is met by specialized medical transport teams such as US Air Force Critical Care Air Transport Teams (CCATT) or by the US Army Burn Flight Team (BFT). Both teams travel with multiple bags or cases of emergency equipment, which are comprehensive but cumbersome. To avoid the need to search multiple bags for equipment or drugs when an in-flight emergency occurs, many CCATT and BFT physicians also carry a personal bag of emergency supplies for rapid access. Over the last year, we have evolved and standardized an emergency equipment bag designed to provide the supplies necessary for initial management of emergencies that occur during flight and ground transport. This or a similar emergency kit would be useful for inter or intrahospital transport of critically ill or injured civilian patients, or for physicians who respond to civil emergencies, such as members of Disaster Medical Assistance Teams.

Abstract
The terrorist attacks of September 11th have prompted interest in developing plans to manage thousands of burn casualties. There is little actual experience in the United States in managing disasters of this magnitude. As an alternative, lessons may be learned from the historical experiences of previous civilian burn or fire disasters occurring in this country. A review of relevant medical, fire service, and popular literature pertaining to civilian burn or fire disasters occurring in the United States between the years 1900 and 2000 was performed. In the 20th century, 73 major U.S. fire or burn disasters have occurred. With each disaster prompting a strengthening of fire regulations or building codes, the number of fatalities per incident has steadily decreased. Detailed examination of several landmark fires demonstrated that casualty counts were great but that most victims had fatal injuries and died on the scene or within 24 hours. A second large cohort comprised the walking wounded, who required minimal outpatient treatment. Patients requiring inpatient burn care comprise a small percentage of the total casualty figure but consume enormous resources during hospitalization. Burn mass casualty incidents are uncommon. The number of casualties per incident decreased over time. In most fire disasters, the majority of victims either rapidly die or have minimal injuries and can be treated and released. As a result, most disasters produce fewer than 25 to 50 patients requiring inpatient burn care. This would be a rational point to begin burn center preparations for mass casualty incidents. A robust outpatient capability to manage the walking wounded is also desirable.

Abstract
A regional burn disaster plan for 24 burn centers located in 11 states comprising the Southern Region of the American Burn Association was developed using online and in-person collaboration between burn center directors during a 2-year period. The capabilities and preferences of burn centers in the Southern Region were queried. A website with disaster information, including a map of regional burn centers and spreadsheet of driving distances between centers, was developed. Standard terminology for burn center capabilities during disasters was defined as open, full, diverting, offloading, or returning. A simple, scalable, and flexible disaster plan was designed. Activation and escalation of the plan revolves around the requirements of the end user, the individual burn center director. A key provision is the designation of a central communications point colocated at a burn center with several experienced burn surgeons. In a burn disaster, the burn center director can make a single phone call to the communications center, where a senior burn surgeon remote from the disaster can contact other burn centers and emergency agencies to arrange assistance. Available options include diversion of new admissions to the next closest center, transfer of patients to other regional centers, or facilitation of activation of federal plans to bring burn care providers to the affected burn center. Cooperation between regional burn center directors has produced a simple and flexible regional disaster plan at minimal cost to institute or operate.

Abstract
Management of chronic wounds has progressed from merely assessing the status of a wound to understanding the underlying molecular and cellular abnormalities that prevent the wound from healing. The concept of wound bed preparation has simultaneously evolved to provide a systematic approach to removing these barriers to natural healing and enhancing the effects of advanced therapies. This brief review of wound bed preparation traces the development of these concepts and explains how to apply systematic wound management using the TIME acronym - tissue (non viable or deficient), infection/inflammation, moisture (imbalance) and edge (non advancing or undermined).

Abstract
OBJECTIVE To assess outcome differences between locally burned civilians and military personnel burned in a distant combat zone treated in the same facility. SUMMARY BACKGROUND DATA The United States Army Institute of Surgical Research (USAISR) Burn Center serves as a referral center for civilians and is the sole center for significant burns in military personnel. We made the hypothesis that outcomes for military personnel burned in the current conflict in Iraq and Afghanistan would be poorer because of delays to definitive treatment, other associated injury, and distance of evacuation. METHODS We reviewed the civilian and military records of patients treated at the USAISR from the outset of hostilities in Iraq in April 2003 to May 2005. Demographics, injury data, mortality, and clinical outcomes were compared. RESULTS : We cared for 751 patients during this time period, 273 of whom were military (36%). Military injuries occurred in a younger population (41 +/- 19 vs. 26 +/- 7 years for civilian and military respectively, P < 0.0001) with a longer time from injury to burn center arrival (1 +/- 5 days vs. 6 +/- 5, P < 0.0001), a higher Injury Severity Score (ISS 5 +/- 8 vs. 9 +/- 11, P < 0.0001), and a higher incidence of inhalation injury (8% vs. 13%, P = 0.024). Total burn size did not differ. Mortality was 7.1% in the civilian and 3.8% in the military group (P = 0.076). When civilians outside the age range of the military cohort were excluded, civilian mortality was 5.0%, which did not differ from the military group (P = 0.57). Total body surface area (TBSA) burned, age > or =40 years, presence of inhalation injury, and ventilator days were found to be important predictors of mortality by stepwise regression, and were used in a final predictive model with the area under receiver operator characteristic curve of 0.97 for both populations considered together. No significant effect of either group was identified during development. CONCLUSIONS Mortality does not differ between civilians evacuated locally and military personnel injured in distant austere environments treated at the same center.

Abstract
Thermal injury historically constitutes approximately 5% to 20% of conventional warfare casualties. This article reviews medical planning for burn care during war in Iraq and experience with burns during the war at the US Army Burn Center; aboard the USNS Comfort hospital ship; and at Combat Support Hospitals in Iraq and in Afghanistan. Two burn surgeons were deployed to the military hospital in Landstuhl, Germany, and to the Gulf Region to assist with triage and patient care. During March 2003 to May 2004, 109 burn casualties from the war have been hospitalized at the US Army Burn Center in San Antonio, Texas, and US Army Burn Flight Teams have moved 51 critically ill burn casualties to the Burn Center. Ten Iraqi burn patients underwent surgery and were hospitalized for up to 1 month aboard the Comfort, including six with massive wounds. Eighty-six burn casualties were hospitalized at the 28th Combat Support Hospital for up to 53 days. This experience highlights the importance of anticipating the burn care needs of both combatants and the local civilian population during war.

Abstract
High-voltage electric injury (HVEI) is associated with a high incidence of extremity compartment syndrome and of major amputation. The purpose of this study was to review our experience with HVEI and to attempt to develop predictors of the need for fasciotomy and amputation in patients with HVEI. The records of the 195 patients with HVEI who were admitted to a single burn center during a 19-year period were reviewed. Evidence for muscle necrosis, to include myoglobinuria and elevated creatine phosphokinase (CPK) levels, was noted. A total 187 patients (95.9%) survived to hospital discharge. A total of 56 underwent fasciotomy within 24 h of injury; 80 patients underwent an amputation during the hospitalization. Fasciotomy was predicted by presence of myoglobinuria with an overall accuracy of 72.8%. Amputation was predicted by a logistic model incorporating myoglobinuria, undergoing a previous fasciotomy, and age, with an overall accuracy of 73.3%. HVEI was associated with high amputation risk and a low rate of mortality in patients admitted to our burn center. Patients with gross myoglobinuria are at higher risk of requiring fasciotomy and/or amputation.

Abstract
UNLABELLED Approximately 13% of thermally injured patients fail resuscitation, in that they die during the first 48 h postburn despite full resuscitative efforts. The purpose of this study was to characterize these patients, and to develop a predictor of resuscitation failure. METHODS Records of 3807 thermally injured patients admitted to this burn centre during 1980-1997 were reviewed. Patients were classified as surviving to hospital discharge ("NONFAIL/LIVE"), as surviving resuscitation but dying later ("NONFAIL/DIE"), or as failing resuscitation ("FAIL"). Ordinal logistic regression was used to develop a predictor of membership in each of these three groups. RESULTS With respect to total burn size, full-thickness burn size, and inhalation injury, the three groups represented a gradation in injury severity from least severe (NONFAIL/LIVE) to most severe (FAIL). The predictive model had an overall accuracy of 91.6%; however, it correctly classified NONFAIL/LIVE patients more often (97.7% accuracy) than it did NONFAIL/DIE patients (57.5%) or FAIL patients (16.1%). CONCLUSION Patients who failed resuscitation were more severely injured than those who survived resuscitation, but was not possible accurately to predict who will fail resuscitation using data available on admission.

Abstract
The Advanced Burn Life Support Course has been used to train military physicians and nurses for more than 16 years. Although it useful for teaching the fundamentals of burn care, the course is designed for a civilian audience, covers only the first 24 hours of burn care, and presumes the availability of a burn center for patient transfer. In preparation for hostilities in Iraq, we developed several add-on modules to the standard Advanced Burn Life Support course to meet specific needs of military audiences. These modules cover the treatment of white phosphorus burns; the treatment of mustard gas exposure; the long-range aeromedical transfer of burn patients; the management of burn patients beyond the first 24 hours; and the delivery of burn care in austere environments. These add-on modules are termed Combat Burn Life Support. Between January 22, 2003, and May 12, 2003, Advanced Burn Life Support and/or Combat Burn Life Support courses were provided to a total of 1035 military health care providers in the United States, Germany, and the Middle East. Student feedback was largely positive and is being used for further course refinement. The Combat Burn Life Support Course is designed to augment, rather than replace, the Advanced Burn Life Support Course. Although intended for a military audience, the course material is equally applicable to civilian terrorist or mass casualty situations.

Abstract
Medical planning for Operation Iraqi Freedom included predictive models of expected number of burn casualties. In all but the best-case scenario, casualty estimates exceeded the capacity of the only Department of Defense burn center. Examination of existing federal-civilian disaster plans for military hospital augmentation revealed that bed availability data were neither timely nor accurate. Recognizing the need for accurate knowledge of burn bed availability, the Department of Defense requested assistance from the American Burn Association (ABA). Directors of burn centers in the United States were queried for interest in participation in a mass casualty plan to provide overflow burn bed capacity. A list of 70 participating burn centers was devised based upon proximity to planned military embarkation points. A computer tracking program was developed. Daily automated e-mail messages requesting bed status were sent to burn center directors at 6 am Central time with responses requested before 11 am. The collated list of national overflow burn bed capacity was e-mailed each day to the ABA Central Office and to federal and military agencies involved with burn patient triage and transportation. Once automated, this task required only 1-2 hours a day. Available burn-bed lists were generated daily between March 17 and May 2, 2003 and then every other day until May 9, 2003. A total of 2151 responses were received (mean, 43 burn centers per day). A system to track daily nationwide burn bed availability was successfully implemented. Although intended for military conflict, this system is equally applicable to civilian mass casualty situations. We advocate adoption of this or a similar bed tracking system by the ABA for use during burn mass casualty incidents.

Abstract
This report describes the initial hospital and burn center management of a mass casualty incident resulting from an aircraft crash and fire. One hundred thirty soldiers were injured, including 10 immediate fatalities. Womack Army Medical Center at Fort Bragg, North Carolina, managed the casualties and began receiving patients 15 minutes after the crash. As a result of repetitive training that included at least two mass casualty drills each year, the triage area and emergency department were cleared of all patients within 2 hours. Fifty patients were transferred to burn centers, including 43 patients to the US Army Institute of Surgical Research. This constitutes the largest single mass casualty incident experienced in the 57-year history of the Institute. All patients of the US Army Institute of Surgical Research survived to hospital discharge, and 34 returned to duty 3 months after the crash. The scenario of an on-ground aircraft explosion and fire approximates what might be seen as a result of an aircraft hijacking, bombing, or intentional crash. Lessons learned from this incident have utility in the planning of future response to such disasters.

Abstract
UNLABELLED Chemical burn injury meets the criteria of the American Burn Association for treatment at a specialized burn facility. Over a 51-year period, we have treated 276 patients with chemical burn injury including 146 white phosphorus injuries. In this study, we compare incidence, cause and outcome of chemical burn injury over time and review the management of white phosphorus injuries. METHODS Data for the period 1986-2000 was obtained by retrospective chart review. Data for the period 1950-1985 was obtained from previous studies and from retrospective chart review. RESULTS Chemical burn injury comprised 2.1% of all admissions between 1969 and 1985, and 2.07% between 1986 and 2000. The mean body surface area involved was 19.5% in the first 19 years of the study compared with 8.6% over the last 15 years. Mortality increased from 5.4% between 1950 and 1968 to 13.8% between 1969 and 1985. Mortality from 1986 to 2000 was 0%. Hospital length of stay decreased from a mean of 90 days in the first 19 years of the study to a mean of 15 days in the most recent 15-year period. The chemical responsible for injury was white phosphorus in 146 cases. CONCLUSIONS Over time, the proportion of burn center admissions caused by chemical injury is constant, while the average total burn size, full thickness burn size, length of stay and mortality have decreased. During peacetime, the chemicals responsible are similar to those seen in civilian burn centers. The experience of this center with burns caused by white phosphorus is unique and needs to be maintained for future conflicts.

Abstract
BACKGROUND We determined whether factors present soon after burn predict which patients will receive more than 4 mL/kg/% burn during the first 24 hours, and whether total fluid intake during the first 24 hours (VOL) contributes to in-hospital mortality (MORT). METHODS We reviewed the records of patients admitted during 1987-97. The modified Brooke resuscitation formula was used. One hundred four patients met inclusion criteria: total body surface area burned (TBSA) > or = 20%; admission directly from the field; weight > 30 kg; no electric injury, mechanical trauma, or blood transfusions; and survival > or = 24 hours postburn. Eighty-nine records were complete. RESULTS Mean TBSA was 43%, mean full-thickness burn size was 21%, mean age was 41 years, mean VOL was 4.9 mL/kg/% burn, and mean lactated Ringer's volume was 4.4 mL/kg/% burn; 53% had inhalation injury. MORT was 25.8%. Mean urine output was 0.77 mL/kg/h. By linear regression, VOL was associated with weight (negatively) and full-thickness burn size (r2 = 0.151). By logistic regression, receipt of over 4 mL/kg/% burn was predicted at admission by weight (negatively) and TBSA; by 24 hours postburn, mechanical ventilation replaced TBSA. With respect to MORT, logistic regression of admission factors yielded a model incorporating TBSA and an age function; by 24 hours postburn, the worst base deficit was added. CONCLUSION Burn size and weight (negatively) were associated with greater VOL. However, a close linear relationship between burn size and VOL was not observed. Mechanical ventilation supplanted TBSA by 24 hours as a predictor of high VOL. Worst base deficit, TBSA, and an age function, but not VOL, were predictors of MORT.

Necrotizing fasciitis is a rapidly progressive soft-tissue infection associated with significant morbidity and mortality. Necrotizing fasciitis is similar to invasive burn wound infection in that diagnosis requires histologic examination of affected tissue and treatment requires aggressive surgical debridement followed by skin autograft. Transfer to a burn center facilitates the management of necrotizing fasciitis, where requisite surgical and nursing expertise is available. We reviewed the experience of one burn center in the management of necrotizing fasciitis over a 5-year period. Ten patients were transferred to the burn center from other medical facilities for care, arriving a mean of 8.9 days after initial hospital admission. The diagnosis was made by a surgical service or consultation before transfer in all cases; initial admission to a medical rather than a surgical service delayed surgery in five cases. All patients had surgical debridement before transfer but required a mean of 5.1 additional operations at the burn center. Although the mean extent of involvement was 14.8% body surface area, the mean length of burn center stay was 34.9 days. Complications were frequent, including pulmonary failure requiring mechanical ventilation (n = 6), renal insufficiency or failure (n = 5), hypotension requiring pressers (n = 4), deep venous thrombosis (n = 3), and pulmonary emboli (n = 1). Overall mortality was 2 of 10 patients (20%). Both fatalities were associated with delay in initial surgical procedure and in transfer to the burn center. The similarity of necrotizing fasciitis and invasive burn wound infection makes the burn center the ideal setting for the treatment of this disease. We advocate the addition of necrotizing fasciitis to the list of conditions currently recognized by the American Burn Association as appropriate for burn center transfer and care.

Abstract
Despite multiple advances in critical care patients with severe adult respiratory distress syndrome (ARDS) can exhaust the capability of conventional ventilation; this results in respiratory failure and death. High-frequency percussive ventilation (HFPV), which was initially utilized for salvage of burn patients with smoke inhalation injury refractory to conventional ventilation, has evolved as a standard of burn care. Based on our experience with HFPV in burn patients the burn team was consulted to provide salvage ventilation for non-burn surgical intensive care unit patients with refractory respiratory failure. Over a 14-month period ten patients with refractory ARDS from multiple causes were treated. Retrospective chart review was performed. Respiratory parameters were assessed before and 24 hours after initiation of HFPV. Mean values of fraction of inspired oxygen (FiO2), pH, partial pressure of O2 in arterial blood (PaO2), partial pressure of CO2 in arterial blood (PaCO2), HCO3, oxygen saturation in arterial blood (SaO2), PaO2/FiO2, and peak inspiratory pressure were compared. Significant improvement in oxygenation was reflected by increases in SaO2, PaO2, and the PaO2/FiO2 ratio in the first 24 hours of HFPV. No significant increase in peak inspiratory pressure was documented by conversion from conventional ventilation to HFPV. No hemodynamic changes directly associated with HFPV were noted. Seven of ten patients failing conventional ventilation survived to hospital discharge after salvage therapy with HFPV. We advocate further studies of HFPV in non-burn patients with ARDS both as salvage therapy and as replacement for conventional ventilation for the initial treatment for ARDS.

Abstract
Burns to the hand that are complicated by exposure of bone, joint or tendon cannot be closed with conventional skin grafts and require flap procedures to prevent further damage. Local or regional flaps may be unavailable if electrical or blast trauma produces a large zone of injury, or when forearm burn injury extends beyond fascia. Free tissue transfer may not be tolerated by critically ill burn patients. In these circumstances, distant pedicle flaps are one option for safe and effective soft tissue coverage. Over a 5-year period, we have performed six distal pedicle flaps for coverage of exposed hand structures when local or free flaps were contraindicated or unavailable. The patients required an average of 4.5 surgical procedures to complete hand reconstruction and soft tissue coverage. Soft tissue coverage was completely successful in five patients and partially successful in one patient. Single stage local or free flaps remain the treatment of choice when burned hands cannot be covered with skin grafts. When these flap options are not available, distant pedicle flaps provide a safe alternative.

Abstract
A burn injury may occur as an unexpected consequence of medical treatment. We examined the burn prevention implications of injuries received in a medical treatment facility or as a direct result of medical care. The records of 4510 consecutive admissions to 1 burn center between January 1978 and July 1997 were retrospectively reviewed. A cohort of 54 patients burned as a result of medical therapy was identified and stratified by location (home vs medical facility) and by mechanism of injury. Twenty-two patients were burned in a medical treatment facility, including 12 patients who were burned as a result of careless or unsupervised use of tobacco products. Thirty-two patients were burned as a result of home medical therapy, including 9 patients who had scald injuries from vaporizers, 8 patients who were burned by simultaneous use of cigarettes and home nasal oxygen therapy, and 11 patients who were burned by therapeutic application of heat. In contrast to previous studies, no patient was burned by the use of medical laser devices. To further decrease burn risk from medical therapy we advocate the prohibition of cigarette smoking in any medical facility. Continued tobacco use may represent a contraindication to home oxygen therapy. Given the lack of proof of efficacy combined with the potential for burn injury, the use of vaporizers to treat upper respiratory symptoms should be discouraged. Patients with diminished sensation or altered mental status are at increased risk of burn injury from bathing or topical heat application and merit closer monitoring during these activities.

Abstract
Cigarettes are the most common ignition source for fatal house fires, which cause approximately 29% of the fire deaths in the United States. A common scenario is the delayed ignition of a sofa, chair, or mattress by a lit cigarette that is forgotten or dropped by a smoker whose alertness is impaired by alcohol or medication. Cigarettes are designed to continue burning when left unattended. If they are dropped on mattresses, upholstered furniture, or other combustible material while still burning, their propensity to start fires varies depending on the cigarette design and content. The term "fire-safe" has evolved to describe cigarettes designed to have a reduced propensity for igniting mattresses and upholstered furniture. Legislative interest in the development of fire-safe smoking materials has existed for more than 50 years. Studies that showed the technical and economic feasibility of commercial production of fire-safe cigarettes were completed more than 10 years ago. Despite this, commercial production of fire-safe smoking materials has not been undertaken. The current impasse relates to the lack of consensus on a uniform test method on which to base a standard for fire-safe cigarettes. Although the fire-safe cigarette is a potentially important burn prevention tool, commercial production of such cigarettes will not occur until a standard against which fire-starting performance can be measured has been mandated by law at the state or federal level. The burn care community can play a leadership role in such legislative efforts.

Abstract
Respiratory failure that requires endotracheal intubation is an uncommon but potentially fatal complication of scald burns in children. Because scalds are rarely associated with a direct pulmonary injury, the pathophysiology of respiratory failure is unclear. A possible mechanism may be upper airway edema, diminished pulmonary compliance secondary to fluid resuscitation, or both. To identify an at-risk population for intubation after a scald injury, the hospital courses of 174 consecutive patients under the age of 14 years who were admitted after a scald injury to a single burn center during a 6-year period were examined. Seven of these patients (4%) required endotracheal intubation. No patient older than 2.8 years or who had a scald injury that covered less than 19% of the total body surface area required intubation. Patients who required intubation were younger (mean age, 1.4 vs. 2.8 years, P<.001), had a larger mean burn size (29.9% vs. 12.3% total body surface area, P<.001), and required more fluid resuscitation (7.66 vs. 4.07 cc/kg per percentage of total body surface area burned, P<.001) than patients who did not require intubation. Examination of the adequacy of resuscitation revealed that the intubated patients had an average hourly urine output of 0.84 cc/kg during the first 24 hours, suggesting that resuscitation was not excessive. Multivariate analysis demonstrated that both larger burn size (P = .041) and younger age (P = .049) were independent predictors of the need for intubation. Young patients with large body surface area burns that required large volumes of resuscitation comprise an at-risk group for respiratory failure after a scald injury. Increased vigilance is merited during the resuscitation of these patients.

Abstract
Severe cutaneous disease and injury often is best treated in the specialized treatment environment of a burn center. Skilled burn treatment personnel combine critical care expertise with extensive clinical experience in the management of severe cutaneous injury and disease. In addition to thermal injury, the burn center is the ideal environment for patients with progressive toxic epidermal necrolysis, pemphigoid lesions, and invasive cutaneous infection. Recent research indicates that the burn wound is a dynamic structure whose ultimate extent is modifiable by manipulations of the local anatomic and molecular environment. The many unanswered questions on the pathogenesis and treatment of both the "medical" and "surgical" cutaneous processes require close collaboration between the dermatologist and the burn team.

Abstract
Previous research at this institute has demonstrated that heavy-for-age boys are more burn prone than their normal sized counterparts. As this study is now 26 years old, we reexamined the anthropomorphic indices of 372 children admitted to one burn center between January 1991 and July 1997 to determine if this trend was still evident. Male children were over-represented in the < or =5th and >95th percentiles for both height (p < 0.001, p < 0.05) and weight (p < 0.01, p < 0.001). Female children were over-represented in the < or =5th and > 95th percentiles for height (p < 0.01, p < 0.05). Twenty-eight percent of boys at or below the 5th percentile for weight were burned as a result of known or suspected intentional injury, compared to 5.9% of the entire pediatric burn population. (p < 0.0004). 'Fat boys' continue to be over-represented in the pediatric burn population. Additionally, in the more recent time period, boys at or below the 5th percentile for height or weight and girls= < 5th percentile or >95th percentile for height are also over-represented. The increased frequency of burn injury in small-for-age children may reflect an increased risk of burn injury secondary to neglect or nonaccidental trauma.

Abstract
An estimated 2 million people a year are victims of elder abuse, which ranges from neglect and mistreatment to physical abuse. By the year 2020, a full 22% of the population will be aged 65 or older. This demographic explosion demands that we identify and protect those at risk. To investigate the incidence of elder abuse or neglect (EAN) and to determine clinician awareness of associated risk factors, we conducted a 1-year retrospective review of thermally injured patients aged 60 or older. Data included age, total body surface area burned, mechanism of injury, length of hospital stay, mortality, abuse or neglect risk factors, and referral to the appropriate social agency. We found that our elderly patients (n = 28) were poorly screened for EAN. While 64% to 96% of patients were screened for cognitive impairment, overall health, and financial resources, none were screened for risk factors of emotional isolation. None of the patient's caregivers, including any spouses, roommates, or guardians, were screened for risk factors of substance abuse, familial violence, dependency needs, or external stresses. With the use of available data, we were able to place 11 patients on the following levels of abuse or neglect: 1) low risk for abuse; 2) self-neglect; 3) neglect; and 4) abuse. By this scale, 7 patients (64%) were victims of self-neglect, 3 patients (27%) were victims of neglect, and 1 patient (9%) was a victim of abuse. Adult Protective Services intervened in 2 cases. Recognizing that all cases of EAN should be preventable, we cannot accept the socioeconomic impact of this entity. The 11 patients identified as victims of neglect, self-neglect, or abuse accounted for 135 hospital days and 8 fatalities. Before we can address EAN, health care personnel must be made aware of the problem and routine screening for risk factors must be implemented. The true incidence of EAN is likely underestimated because health care providers have difficulty recognizing its features. A standard assessment tool to screen for neglect or abuse should be used for each older adult admission.

Abstract
Gasoline is intended for use as a motor fuel, but the universal availability of gasoline in the home encourages misuse as a solvent, insecticide, accelerant or cleaning solution. The careless or inappropriate use of gasoline may result in burn injury. We examined the circumstance of gasoline-related injury in a population admitted to one burn centre to determine the potential for burn prevention efforts. A retrospective review of all burn admissions to one centre for the years 1978 to 1996 demonstrated hat 1011 of 4339 acute admissions (23.3%) were gasoline-related. This group had an average total burn size of 29.8% total body surface (TBSA) and an average full thickness injury of 14.4% TBSA. There were 144 fatalities resulting from gasoline-associated burn injury. Where such determination could be made, the use of gasoline was judged to be inappropriate or unsafe in 687 of 788 cases (87.1%). Ninety of 144 fatalities (62.5%) were associated with inappropriate or unsafe use of gasoline. The careless or inappropriate use of gasoline poses significant risk of burn injury. The indoor use of gasoline, as well as use of gasoline for purposes other than as a motor fuel, should be strongly discouraged.

Abstract
Cosmetic liposuction is considered to be safe and effective in properly selected patients and is widely done as an outpatient or office procedure. When major complications occur, office-based practitioners may refer patients to a hospital emergency department, where medical personnel unfamiliar with this procedure may underestimate the risk of serious infection or other major complications. We present two cases of massive necrotizing fasciitis treated in a burn center after liposuction surgery. One patient died, and the second required lengthy hospitalization, extensive debridement, and split-thickness skin grafting of 22% of the total body surface area. Pain out of proportion to clinical findings is a hallmark of necrotizing fasciitis and should prompt consideration of this entity even in the absence of cutaneous signs of infection. Definitive diagnosis is made by biopsy and rapid section histologic analysis. Liposuction may result in major complications or death. Emergency department physicians or general surgeons may be called upon to manage such complications and should be aware of these risks.

Abstract
Treatment protocols for the management of burned hands are essential for integrating team efforts and achieving optimal functional results. Standard protocols are especially useful during mass casualty incidents, when the admission of multiple patients with large burns and/or associated injuries may reduce the priority usually accorded the hands. We prospectively evaluated a surgical and rehabilitative treatment protocol for burned hands during a mass casualty incident, after which 43 burn patients with 82 burned hands were admitted to one burn center. Soft-tissue management was individualized to achieve, if possible, wound closure within 14 days, and included the use of topical antimicrobials, cutaneous debridement and/or tangential excision, biologic dressings, and split-thickness autografts. Range of motion therapy was based on daily measurement of active motion of the metacarpophalangealjoints. Static splinting alternating with continuous passive motion every 4 hours was utilized for sedated patients. Continuous passive motion alternating with active ranging and night splinting was utilized for metacarpophalangeal flexion <70 degrees. Active ranging and progressive resistance was utilized for metacarpophalangeal flexion > or =70 degrees. Sixty-four hands required excision and grafting, with 89 percent having at least one autografting procedure completed by postburn day 16. Total active motion of the hands treated averaged 220.6 degrees on discharge and 229.9 degrees at 3 months after injury. Mean hand grip strength was 60.8 pounds at discharge and 66.0 pounds at 3 months after injury. Adherence to a standard hand burn protocol resulted in timely wound coverage and recovery of hand function for a large group of patients treated at a single burn facility after a mass casualty incident.

Abstract
The return to optimal function for patients who sustain chemical and electrical injuries depends on immediate emergency treatment and burn center referral for definitive care. Patients with exfoliating diseases also require care provided by a burn center. Critical care nurses, along with other members of a multidisciplinary health care team, must be dedicated to the principles of infection control, pain management, and psychosocial care to ensure positive outcomes and the return of these citizens to society.
