Abstract
OBJECTIVES ABRUPT was a prospective, noninterventional, observational study of resuscitation practices at 21 burn centers. The primary goal was to examine burn resuscitation with albumin or crystalloids alone, to design a future prospective randomized trial. SUMMARY BACKGROUND DATA No modern prospective study has determined whether to use colloids or crystalloids for acute burn resuscitation. METHODS Patients ≥18 years with burns ≥ 20% total body surface area (TBSA) had hourly documentation of resuscitation parameters for 48 hours. Patients received either crystalloids alone or had albumin supplemented to crystalloid based on center protocols. RESULTS Of 379 enrollees, two-thirds (253) were resuscitated with albumin and one-third (126) were resuscitated with crystalloid alone. Albumin patients received more total fluid than Crystalloid patients (5.2 ± 2.3 vs 3.7 ± 1.7 mL/kg/% TBSA burn/24 hours), but patients in the Albumin Group were older, had larger burns, higher admission Sequential Organ Failure Assessment (SOFA) scores, and more inhalation injury. Albumin lowered the in-to-out (I/O) ratio and was started ≤12 hours in patients with the highest initial fluid requirements, given >12 hours with intermediate requirements, and avoided in patients who responded to crystalloid alone. CONCLUSIONS Albumin use is associated with older age, larger and deeper burns, and more severe organ dysfunction at presentation. Albumin supplementation is started when initial crystalloid rates are above expected targets and improves the I/O ratio. The fluid received in the first 24 hours was at or above the Parkland Formula estimate.

Abstract
As the wars in Iraq and Afghanistan end, the US military has begun to transition to the multi-domain operations concept with preparation for large scale combat operations against a near-peer adversary. In large scale combat operations, the deployed trauma system will likely see challenges not experienced during the Global War on Terrorism. The development of science and technology will be critical to close existing capability gaps and optimize casualty survival. This review comprises a framework of deployed trauma care to provide nonmilitary investigators a general understanding of our deployed trauma care system. Trauma care begins at the Role 1 which encompasses all care from the point of injury and the battalion aid station, through transport to the Role 2 or forward staged mobile surgical team such as a Forward Resuscitative Surgical Detachment. Role 1 point of injury care approximates the care delivered by Emergency Medical Services (EMS) personnel. The Battalion Aid Station approximates the care available at a freestanding emergency center with significant differences in training level of the providers, number of beds, and diagnostic capabilities. Role 2 medical care is part of an area support medical company with surgical capabilities. The Role 2 represents the first role of care which provides damage control surgery. This capability approximates a small community hospital with the primary difference being limited patient holding capacity and reduced diagnostic equipment. The Role 3 field hospital is the largest military treatment facility in the deployed setting. The Role 3 approximates a civilian level 2 trauma center with smaller holding capabilities and diagnostic abilities limited to that of a computed tomography (CT) scanner and less.

Abstract
INTRODUCTION The US military is transitioning into a posture preparing for large-scale combat operations in which delays in evacuation may become common. It remains unclear which casualty population can have their initial surgical interventions delayed, thus reducing the evacuation demands. METHODS We performed a secondary analysis of a previously described dataset from the Department of Defense Trauma Registry (DODTR) focused on casualties who received prehospital care. In this, we sought to determine (1) of those who underwent operative intervention, the proportion of surgeries occurring ≥3 days post-injury, and (2) of those who underwent early versus delayed surgery, the proportions who required blood products. RESULTS There were 6,558 US military casualties who underwent surgical intervention-6,224 early (less than 3 days from injury) and 333 delayed (≥ 3 days from injury). The median Injury Severity Score (ISS) was higher in the early cohort (10 versus 6, p is less than 0.001). Serious injuries to the head were more common in the early cohort (12% versus 5%, p is less than 0.001), as were the thorax (13% versus 9%, p=0.041), abdomen (10% versus 5%, p=0.001), extremities (37% versus 14%, p is less than 0.001), and skin (4% versus less than 1%, p=0.001). Survival to discharge was lower in the early cohort (97% versus 100%, p is less than 0.001). Mean whole blood consumption was higher in the early cohort (0.5 versus 0 units, p is less than 0.001), as was packed red blood cells (6.3 versus 0.5, p is less than 0.001), platelets (0.9 versus 0, p is less than 0.001), and fresh frozen plasma (4.5 versus 0.2, p is less than 0.001). The administration of any units of packed red blood cells and whole blood was higher for the early cohort (37% versus 7%, p is less than 0.001), as was a ≥3 units threshold (30% versus 3%, p is less than 0.001), and ≥10 units threshold (18% versus 1%, p is less than 0.001). CONCLUSIONS Few combat casualties underwent delayed surgical interventions defined as ≥3 days post injury, and only a small number of casualties with delayed surgical intervention received blood products. Casualties who received early surgical intervention were more likely to have higher injury severity scores, and more likely to receive blood.

Abstract
Major trauma frequently occurs in the deployed, combat setting and is especially applicable in the recent conflicts with explosives dominating the combat wounded. In future near-peer conflicts, we will likely face even more profound weapons including mortars and artillery. As such, the number of severely wounded will likely increase. Hypocalcemia frequently occurs after blood transfusions, secondary to the preservatives in the blood products; however, recent data suggests major trauma in and of itself is a risk factor for hypocalcemia. Calcium is a major ion involved in heart contractility; thus, hypocalcemia can lead to poor contractility. Smaller studies have linked hypocalcemia to worse outcomes, but it remains unclear what causes hypocalcemia and if intervening could potentially save lives. The objective of this study is to determine the incidence of hypocalcemia on hospital arrival and the association with survival. We are seeking to address the following scientific questions, (1) Is hypocalcemia present following traumatic injury prior to transfusion during resuscitation? (2) Does hypocalcemia influence the amount of blood products transfused? (3) To what extent is hypocalcemia further exacerbated by transfusion? (4) What is the relationship between hypocalcemia following traumatic injury and mortality? We will conduct a multicenter, prospective, observational study. We will gather ionized calcium levels at 0, 3, 6, 12, 18, and 24 hours as part of scheduled calcium measurements. This will ensure we have accurate data to assess the early and late effects of hypocalcemia throughout the course of resuscitation and hemorrhage control. These data will be captured by a trained study team at every site. Our findings will inform clinical practice guidelines and optimize the care delivered in the combat and civilian trauma setting. We are seeking 391 patients with complete data to meet our a priori inclusion criteria. Our study will have major immediate short-term findings including risk prediction modeling to assess who is at risk for hypocalcemia, data assessing interventions associated with the incidence of hypocalcemia, and outcome data including mortality and its link to early hypocalcemia.

Abstract
BACKGROUND Correct identification and rapid intervention of a traumatic pneumothorax is necessary to avoid hemodynamic collapse and subsequent morbidity and mortality. The purpose of this clinical review is to summarize the evaluation and best treatment strategies to improve outcomes in combat casualties. Blunt, explosive, and penetrating trauma are the 3 etiologies for causing a traumatic pneumothorax. Blunt trauma tends to be more common, but all etiologies require similar treatment. The current standard to diagnose pneumothorax is through imaging to include ultrasound, chest x-ray, or computed tomography. A physical exam aids in the diagnosis especially when few other resources are available. Recent studies on the treatment of a small, closed pneumothorax involve conservative care, which includes close observation of the patient and monitoring supplemental oxygen. For a large, closed pneumothorax, conservative treatment is still a possible option, but manual aspiration may be required. Less often, a needle or tube thoracostomy is needed to reinflate the lung. Large, open pneumothoraxes require the most invasive treatment with current guidelines recommending tube thoracostomy. More invasive management options can result in higher rates of complications. Given the significant variability in practice patterns, most notable in resource limited settings, the areas for potential research are presented.

Abstract
INTRODUCTION Atrial fibrillation is associated with increased morbidity and mortality in critically ill patients. Few studies have specifically examined this arrhythmia in burn patients. Given the significant clinical implications of atrial fibrillation, understanding the optimal management strategy of this arrhythmia in burn patients is important. Consequently, the purpose of this study was to examine rate- and rhythm-control strategies in the management of new onset atrial fibrillation (NOAF) and assess their short term outcomes in critically ill burn patients. METHODS We identified all patients admitted to our institution's burn intensive care unit between January 2007 and May 2018 who developed NOAF. Demographic information and burn injury characteristics were captured. Patients were grouped into two cohorts based on the initial pharmacologic treatment strategy: rate-(metoprolol or diltiazem) or rhythm-control (amiodarone). The primary outcome was conversion to sinus rhythm. Secondary outcomes included relapse or recurrence of atrial fibrillation, drug-related adverse events, and complications and mortality within 30 days of the NOAF episode. RESULTS There were 68 patients that experienced NOAF, and the episodes occurred on median days 8 and 9 in the rate- and rhythm-control groups, respectively. The length of the episodes was not significantly different between the groups. Conversion to sinus rhythm occurred more often in the rhythm-control group (P = 0.04). There were no differences in the incidences of relapse and recurrence of atrial fibrillation, and the complications and mortality between the groups. Hypotension was the most common drug-related adverse event and occurred more frequently in the rate-control group, though this difference was not significant. CONCLUSIONS Conversion to sinus rhythm occurred more often in the rhythm-control group. Outcomes were otherwise similar in terms of mortality, complications, and adverse events. Hypotension occurred less frequently in the rhythm-control group, and although this difference was not significant, episodes of hypotension can have important clinical implications. Given these factors, along with burn patients having unique injury characteristics and a hypermetabolic state that may contribute to the development of NOAF, when choosing between rate- and rhythm control strategies, rhythm-control with amiodarone may be a better choice for managing NOAF in burn patients.

Abstract
Tracheal intubation is the preferred method of airway management, a common emergency trauma medicine problem. Currently, methods for confirming tracheal tube placement are lacking, and we propose a novel technology, spectral reflectance, which may be incorporated into the tracheal tube for verification of placement. Previous work demonstrated a unique spectral profile in the trachea, which allowed differentiation from esophageal tissue in ex vivo swine, in vivo swine, and human cadavers. The goal of this study is to determine if spectral reflectance can differentiate between trachea and other airway tissues in living humans and whether the unique tracheal spectral profile persists in the presence of an inhalation injury. Reflectance spectra were captured using a custom fiber-optic probe from the buccal mucosa, posterior oropharynx, and trachea of healthy humans intubated for third molar extraction and from the trachea of patients admitted to a burn intensive care unit with and without inhalation injury. Using ratio comparisons, we found that the tracheal spectral profile was significantly different from buccal mucosa or posterior oropharynx, but the area under the curve values are not high enough to be used clinically. In addition, inhalation injury did not significantly alter the spectral reflectance of the trachea. Further studies are needed to determine the utility of this technology in a clinical setting and to develop an algorithm for tissue differentiation.

Abstract
Introduction Managing burn fluid resuscitation for large burns is challenging and relies heavily on accurate nursing documentation. The Burn Navigator (BN) is a clinical decision-support system designed to guide clinicians in burn fluid resuscitation. However, data entered into the BN do not auto-populate into the electronic medical record (EMR), thus requiring nurses to document in two systems. We sought to compare differences in nursing documentation of data entries between the EMR and the BN on burn patients with ≥ 20% total body surface area (TBSA) undergoing intravenous (IV) fluid resuscitation. Methods Institutional Review Board approval was obtained for a multi-center observational study of burn patients undergoing fluid resuscitation using the BN. Data were collected and analyzed between the EMR and BN entries entered into the REDCap database from 5 American Burn Association (ABA)-verified burn centers. The following variables were analyzed: time of burn injury, weight, TBSA burned, urine output (UOP), and hourly IV crystalloid fluid volume. Results Analysis included 296 subjects (of 300 enrolled). Results show no significant difference between burn centers for mean weight (BN 87.02 ± 22.9 kg vs. EMR 87.1 ± 23.3 kg), TBSA (BN 40.71 ± 19.24% vs. EMR 40.97 ± 19.29%), or time of burn injury (< 1 hour). The time of injury recorded in the BN versus EMR was later in 44.6% (n=132) of patients and earlier in 46.4%, (n=138) and the same in 8.8% (n=26) of records. Additionally, in 293 records, there was no significant difference between centers in patient UOP (BN 0.91 ± 0.52 ml/kg/hr vs. EMR 0.91 ± 0.63 ml/kg/hr). One site had a significant difference in hourly fluid rates (Figure) due to a lack of inclusion of pre-hospital fluids. ![]()
Conclusions When comparing the data between the EMR to BN, it was observed that pre-hospital fluids tended not to be documented in the EMR, causing a statistically significant difference in total fluids administered in one burn center. Overall, the nursing documentation variability was minimal across all sites even though the nurses had to document the data in two different systems, while simultaneously caring for critically ill patients with large burn injuries. Close monitoring of the nursing documentation during burn fluid resuscitation should always be a priority.

Abstract
Abstract
Introduction
Burn care continues to focus on providing enough fluid resuscitation to perfuse end organs with the least amount of fluid necessary in order to prevent complications related to excess fluid. In this observational trial of 5 ABA-verified burn centers that utilized the Burn Navigator (BN), a clinical decision support tool, we sought to examine resuscitation-related complications that occurred in the first 48 hours after burn injury. Since minimal literature exists regarding the incidence of resuscitation-related complications in the acute phase after burn injury, we aimed to present our data for future comparison.
Methods
An observational study of adult patients undergoing burn resuscitation utilizing the BN was conducted. Data were gathered hourly for the first 48 hours for patients on fluid infusion rates, laboratory data, critical care elements to include ventilator settings and clinically relevant outcomes. Morbidities were classified based on each burn center’s definition as related to over or under-resuscitation and variables associated with these outcomes were extracted from the data set.
Results
Three hundred patients were enrolled into the study, and 156 resuscitation-related complications were documented in 92 patients in the first 48 hours after admission. Compartment syndromes (abdominal, extremity, ocular) accounted for 62 (40%) of the complications. ARDS occurred in 9 patients. ARDS patients were the most severely injured, reflected by highest Baux score. None of the ARDS patients had an inhalation injury. The under-resuscitation morbidities of shock and acute kidney injury accounted for 81 (52%) of the complications. Patients experiencing shock received greater than the Parkland formula in the first 24 hours after injury. Most patients with AKI continued to make adequate urine during their resuscitation period, with 59% making an average of >30 ml/hr over the first 24 hours. Nearly half of patients with AKI were placed on renal replacement therapy in the first 48 hours. Seventeen patients (18.5%) experienced both a compartment syndrome and either AKI or shock.
Conclusions
This large observational study demonstrates variables associated with different complications across 5 major burn centers and shows that complications associated with over- and under-resuscitation can occur within the same patient during resuscitation after burn injury. Additional comparative studies are needed to better understand the cause of these complications, to determine the incidence of these complications in a larger population and criteria used to define each complication.

Abstract
Abstract
Introduction
The goal of burn resuscitation is to provide the least amount of fluid necessary to maintain end-organ perfusion and prevent burn shock. The objective of this analysis was to examine how the Burn Navigator (BN), a clinical decision support tool in burn resuscitation, was utilized across 5 major burn centers in the United States.
Methods
A non-interventional, observational trial of 300 adult patients with embedded prospective and retrospective components was undertaken to examine the effectiveness of the BN in burn resuscitation. 5 ABA-verified burn centers enrolled patients. Data examining patient demographics, burn characteristics, fluid volumes, and resuscitation-related complications were examined. Statistical analysis compared the 5 sites in terms of these variables.
Results
A total of 285 patients were eligible for analysis. There was no difference among the centers in terms of average age (45.5 + 16.8 years), BMI (29.2 + 6.9), ISS (21.2 + 12.8), or median TBSA (34 [25.8, 47]). Primary crystalloid infusion volumes at 24 hours differed significantly when measured in ml/kg/TBSA (median 3.7 [2.9, 8.8], range 1.3 to 12.3). Similarly, total fluids, which includes colloid adjuncts, drip medications and enteral fluids, differed between groups when measured in both ml/kg (median 149.8 [106.5, 224.1], range 38.4 to 536.2) and ml/kg/TBSA (4.2 [3.3, 5.5], 1.7 to 15.3) at 24 hours. Post-hoc adjustment for pairwise comparisons resulted in a loss of significance between most of the sites. There was a total of 156 resuscitation-related complications reported across the 5 sites with an average incidence of 44.4 % incidence.
Conclusions
The Burn Navigator appeared to standardize fluid resuscitations across 5 major US burn centers. With primary fluid volumes near the Parkland formula, the device can be utilized effectively in burn centers, and further study should exam the utility of this device in facilities that do not commonly treat burn injuries, as well as the battlefield.

Abstract
The objective of this multi-center observational study was to evaluate resuscitation volumes and outcomes of patients who underwent fluid resuscitation utilizing the Burn Navigator (BN), a resuscitation clinical decision support tool. Two analyses were performed: examination of the first 24 hours of resuscitation, and the first 24 hours post-burn regardless of when the resuscitation began, to account for patients who presented in a delayed fashion. Patients were classified as having followed the BN (FBN) if all hourly fluid rates were within ±20 mL of BN recommendations for that hour at least 83% of the time, otherwise they were classified as not having followed BN (NFBN). Analysis of resuscitation volumes for FBN patients in the first 24 hours resulted in average volumes for primary crystalloid) and total fluids administered of 4.07 ± 1.76 mL/kg/TBSA (151.48 ± 77.46 mL/kg), and 4.68 ± 2.06 mL/kg/TBSA (175.01 ± 92.22 mL/kg), respectively. Patients who presented in a delayed fashion revealed average volumes for primary and total fluids of 5.28 ± 2.54 mL/kg/TBSA (201.11 ± 106.53 mL/kg), 6.35 ± 2.95 mL/kg/TBSA (244.08 ± 133.5 mL/kg), respectively. There was a significant decrease in the incidence of burn shock in the FBN group (p< 0.05). This study shows that the BN provides comparable resuscitation volumes of primary crystalloid fluid to the Parkland Formula, recommends total fluid infusion less than the Ivy Index, and was associated with a decreased incidence of burn shock. Early initiation of the BN device resulted in lower overall fluid volumes.

Abstract
Patients who suffer hand burns are at a high contracture risk, partly due to numerous cutaneous functional units, or contracture risk areas, located within the hand. Patients who undergo split-thickness skin grafting are often immobilized postoperatively for graft protection. Recent practice at our burn center includes an early range of motion (EROM) following hand grafting to limit unnecessary immobilization. The purpose of this study was to determine whether EROM is safe to perform after hand grafting and if there is any clinical benefit. This retrospective, matched case-control study of adults compared patients who received EROM to subjects who received the standard 3 to 5 days of postoperative immobilization. Patients were evaluated for graft loss and range of motion. Seventy-one patients were included in this study: 37 EROM patients and 34 matched controls. Six patients experienced minor graft loss, three of these were not attributable to EROM. All graft loss was less than 1 cm and none required additional surgery. Significantly more patients who received EROM achieved full-digital flexion by the first outpatient visit (25/27 = 92.6% vs 15/22 = 68.2%; P = .028). Performing EROM does not cause an increase in graft loss. All areas of graft loss from the EROM group healed without intervention. There appears to be a benefit to EROM since there was a significant improvement in the patients' ability to make a full fist at initial outpatient follow-up. Additional prospective analysis is needed to examine the true clinical utility of EROM in the hand and other contracture-prone areas.

Abstract
BACKGROUND Donated blood is a valuable and limited resource. Excision of burn wounds often leads to significant blood loss requiring transfusion. Accurately estimating blood loss is difficult, so examining the amount of blood products given intraoperatively is a clinically relevant way to measure utilization of this valuable resource. In this study, we examined the factors that influenced the amount of blood given intraoperatively during burn wound excisions. STUDY DESIGN AND METHODS A retrospective analysis of patients admitted to a single burn center over 5 years who underwent excision of their burn wounds and received intraoperative blood products was performed. Patient and burn characteristics as well as pertinent surgical data and laboratory values on the day of surgery and postoperatively were gathered. A linear regression analysis examined factors influencing the number of units of products given and a predictive model was generated. RESULTS A total of 563 operations performed on 166 patients were included. The amount of burn excised was the most influential variable on the amount of blood products given. Hemoglobin level, international normalized ratio, and platelet count on the day of surgery were associated with transfusion of different blood products. A predictive model was generated to aid in preoperative ordering of blood products. CONCLUSION The amount of burn excised and common hematology and coagulation lab values were associated with the amount of different blood products administered during burn surgery. The predictive model generated needs to be validated prospectively to aid in preoperative planning for burn excisions.

Abstract
Hemorrhage is a significant cause of death among military working dogs and in civilian canine trauma. While research specifically aimed at canine trauma is limited, many principles from human trauma resuscitation apply. Trauma with significant hemorrhage results in shock and inadequate oxygen delivery to tissues. This leads to aberrations in cellular metabolism, including anaerobic metabolism, decreased energy production, acidosis, cell swelling, and eventual cell death. Considering blood and endothelium as a single organ system, blood failure is a syndrome of endotheliopathy, coagulopathy, and platelet dysfunction. In severe cases following injury, blood failure develops and is induced by inadequate oxygen delivery in the presence of hemorrhage, tissue injury, and acute stress from trauma. Severe hemorrhagic shock is best treated with hemostatic resuscitation, wherein blood products are used to restore effective circulating volume and increase oxygen delivery to tissues without exacerbating blood failure. The principles of hemostatic resuscitation have been demonstrated in severely injured people and the authors propose an algorithm for applying this to canine patients. The use of plasma and whole blood to resuscitate severely injured canines while minimizing the use of crystalloids and colloids could prove instrumental in improving both mortality and morbidity. More work is needed to understand the canine patient that would benefit from hemostatic resuscitation, as well as to determine the optimal resuscitation strategy for these patients.

Abstract
BACKGROUND Role 2 medical treatment facilities (MTFs) are frequently located in austere settings and have limited resources. A dedicated assessment of burn casualties treated at this level of care has not been performed. Therefore, the objective of this study was to characterize burn casualties presenting to role 2 MTFs in Afghanistan, along with the procedures they required, complications, and mortality to begin understanding the resources consumed by their care. METHODS We identified burn casualties from the Department of Defense Trauma Registry (DODTR). The inclusion criteria were (1) experienced burn injuries in Afghanistan between October 2005 and April 2018 and (2) had documentation of treatment at role 2 in the DODTR. We excluded casualties with only first-degree burns, not otherwise specified burns, or only corneal burns. Casualty demographics, injury characteristics, procedures, and outcomes were reported. RESULTS We identified 453 burn casualties with a median (interquartile range) Injury Severity Score of 10 (4-22) and percent total body surface area burned of 11 (5-30). There were 123 casualties (27.2%) with inhalation injury, and the casualties experienced 3,343 additional traumatic injuries and needed 2,530 procedures. Casualties with documentation of resuscitation information received a median (interquartile range) of 1.9 (0.7-3.7) L of crystalloid fluids. Complications were documented in 53 casualties (11.7%). Final mortality was reported in 36 casualties (8.0%), and mortality at role 2 MTFs was reported in 7 casualties (1.5%). CONCLUSION Burn casualties had many injuries and needed many procedures, including those related to airway management, resuscitation, and wound care. Given the urgency of these procedures, ensuring that there is enough equipment and supplies will be important in the future. Although infrequent, some casualties experienced complications. Factors that may influence resuscitation include injury severity, concomitant traumatic injuries, and available supplies. Obtaining more contextual information on the patient care environment will be useful going forward. LEVEL OF EVIDENCE Epidemiological, level III.

Abstract
Cultured epithelial autografts have been an option for coverage of large surface area burns for over two decades. However, there remains extreme variability in clinical practice in wound bed preparation, application of cultured epithelial autografts, and post-operative wound care and rehabilitation practices, demonstrating the need for a standardized and multidisciplinary approach in the treatment of critically injured patients treated with cultured epithelial autografts. The purpose of this case series was to share the development of a clinical practice guideline and competency checklist in our institution where cultured epithelial autograft case volume is low. In this case series, we examined the medical records of three patients treated with cultured epithelial autografts at a single burn center over a period from 2015-2018. Operating room times and fluid resuscitation volumes were examined on days when cultured epithelial autograft grafting was performed. In order to facilitate meticulous post-operative wound care in a facility where only 1-2 cultured epithelial autograft applications are performed per year, a clinical practice guideline and competency checklist were generated and trialed on a series of nurses and rehabilitation therapists for the three applications of cultured epithelial autografts. Amongst the patients treated with cultured epithelial autografts, the average TBSA burned was 71.6%. Less intra-operative crystalloid administration and faster operative case times were associated with improved cultured epithelial autograft success. The inclusion of the clinical practice guideline and checklist into our practice led to reported improved confidence in patient care, along with the successful outcomes of these cultured epithelial autograft applications.

Abstract
Extubation failure is associated with negative outcomes making the identification of risk factors for failure paramount. Burn patients experience a high incidence of respiratory failure requiring mechanical ventilation. There is no consensus on the acceptable rate of extubation failure and many conventional indices do not accurately predict extubation outcomes in burn patients. The purpose of this study was to examine the rate of extubation failure in the burned population and to examine the impact of factors on extubation outcomes. Burn patients from a single center over 9 years were examined and included if they were intubated prior to arrival or within 48 hours of admission and underwent a planned extubation. From this cohort, a matched case-control analysis based on age, TBSA, and sex was performed of patients who succeeded after extubation, defined as not requiring reintubation within 72 hours, to those who failed. Characteristics and clinical parameters were compared to determine whether any factors could predict extubation failure. There was a 12.3% incidence of extubation failure. In the matched case-control analysis, the presence of inhalation injury was associated with extubation success. Higher heart rate and lower serum pH were associated with extubation failure. ANCOVA analysis demonstrated that a sodium trending higher before extubation was associated with more successes, possibly indicative of a lower volume status. Classic extubation criteria do not accurately predict extubation outcomes in burn patients; analysis of other parameters may be able to provide better predictions. A constellation of these parameters needs to be studied prospectively.

Abstract
INTRODUCTION Acute kidney injury (AKI) is associated with high mortality in burn patients. Previously, we reported that timely initiation of renal replacement therapy (RRT) with an individualized preference toward continuous modes at relatively higher than recommended doses has become standard practice in critically ill burn patients with AKI and is associated with a historically low mortality. The purpose of this cohort analysis was to determine if modality choice impacted survival in burn patients. METHODS After Institutional Review Board approval, a subset analysis was performed on de-identified data collected during a multicenter, observational study. All patients (n = 170) were 18 years or older, admitted with severe burn injuries and started on RRT. Comparisons were made utilizing χ2 or Fisher's exact test. Kaplan-Meier plots were utilized to assess survival. Sample size determinations to aid future research were calculated utilizing χ2 test with a Yates Correction Factor. RESULTS Demographics and revised Baux were similar between groups. When continuous venovenous hemofiltration (CVVH) was compared to all other modalities, there was no statistically significant difference in survival (56 vs. 43%, p = 0.124). However, survival was significantly improved (54 vs. 37%, p = 0.032) in the subset of patients requiring vasopressors (n = 77). There was no statistically significant survival difference in patients with inhalation injury (38 vs. 29%, p = 0.638) or acute lung injury/acute respiratory distress syndrome (51 vs. 33%, p = 0.11). DISCUSSION/CONCLUSION Survival may be improved if CVVH is chosen as the preferred modality in burn patients with shock and requiring RRT. Differences in other subsets were promising, but analysis was underpowered. Further research should determine if modality choice provides survival benefit in any other subset of burn injury.

Abstract
Necrotic tissue generated by a thermal injury is typically removed via surgical debridement. However, this procedure is commonly associated with blood loss and the removal of viable healthy tissue. For some patients and contexts such as extended care on the battlefield, it would be preferable to remove devitalized tissue with a nonsurgical debridement agent. In this paper, a proprietary debridement gel (SN514) was evaluated for the ability to debride both deep-partial thickness (DPT) and full-thickness burn wounds using an established porcine thermal injury model. Burn wounds were treated daily for 4 days and visualized with both digital imaging and laser speckle imaging. Strip biopsies were taken at the end of the procedure. Histological analyses confirmed a greater debridement of the porcine burn wounds by SN514 than the vehicle-treated controls. Laser speckle imaging detected significant increases in the perfusion status after 4 days of SN514 treatment on DPT wounds. Importantly, histological analyses and clinical observations suggest that SN514 gel treatment did not damage uninjured tissue as no edema, erythema, or inflammation was observed on intact skin surrounding the treated wounds. A blinded evaluation of the digital images by a burn surgeon indicated that SN514 debrided more necrotic tissue than the control groups after 1, 2, and 3 days of treatment. Additionally, SN514 gel was evaluated using an in vitro burn model that used human discarded skin. Treatment of human burned tissue with SN514 gel resulted in greater than 80% weight reduction compared with untreated samples. Together, these data demonstrate that SN514 gel is capable of debriding necrotic tissue and suggest that SN514 gel could be a useful option for austere conditions, such as military multi-domain operations and prolonged field care scenarios.

Abstract
BACKGROUND In allergic rhinitis, a relevant outcome providing information on the effectiveness of interventions is needed. In MASK-air (Mobile Airways Sentinel Network), a visual analogue scale (VAS) for work is used as a relevant outcome. This study aimed to assess the performance of the work VAS work by comparing VAS work with other VAS measurements and symptom-medication scores obtained concurrently. METHODS All consecutive MASK-air users in 23 countries from 1 June 2016 to 31 October 2018 were included (14 189 users; 205 904 days). Geolocalized users self-assessed daily symptom control using the touchscreen functionality on their smart phone to click on VAS scores (ranging from 0 to 100) for overall symptoms (global), nose, eyes, asthma and work. Two symptom-medication scores were used: the modified EAACI CSMS score and the MASK control score for rhinitis. To assess data quality, the intra-individual response variability (IRV) index was calculated. RESULTS A strong correlation was observed between VAS work and other VAS. The highest levels for correlation with VAS work and variance explained in VAS work were found with VAS global, followed by VAS nose, eye and asthma. In comparison with VAS global, the mCSMS and MASK control score showed a lower correlation with VAS work. Results are unlikely to be explained by a low quality of data arising from repeated VAS measures. CONCLUSIONS VAS work correlates with other outcomes (VAS global, nose, eye and asthma) but less well with a symptom-medication score. VAS work should be considered as a potentially useful AR outcome in intervention studies.

Abstract
Acute kidney injury (AKI) is associated with high mortality in burn patients. Urinary biomarkers can aid in the prediction of AKI and its consequences, such as death and the need for renal replacement therapy (RRT). The purpose of this study was to investigate a novel methodology for detecting urinary biomarkers, the NephroCheck® Test System, and assess its ability to predict death or the need for RRT in burn patients. Burn patients admitted to the United States Army Institute of Surgical Research (USAISR) burn intensive care unit were prospectively enrolled between March 2016 and April 2018. A urine sample was obtained from all study participants using the NephroCheck® system. Patient and injury characteristics were gathered, and descriptive statistics were calculated and multivariable logistic regression analyses were performed using these data. Of the 69 patients in this study, 15 patients (21.7%) attained the composite outcome of death or needing RRT within 30 days of urine collection. NephroCheck® scores were higher for patients with the composite outcome, with P = 0.06 for centrifuged scores and P = 0.04 for noncentrifuged scores. Centrifuged and noncentrifuged scores were in high agreement and correlation (R2 = 0.97, P < 0.0001). Noncentrifuged scores were significant in the unadjusted analysis, but they were not significant in the adjusted analysis. Although these scores had a lower sensitivity and negative predictive value compared with other parameters, they had the second highest specificity and positive predictive value. NephroCheck® scores were higher in burn patients with the composite outcome of death or needing RRT, and they demonstrated comparable sensitivity and specificity to creatinine and TBSA.

Abstract
Abstract
Introduction
Patients who suffer hand burns are at a high risk for developing contractures, partly due to the presence of numerous cutaneous functional units, or contracture risk areas, located within the hand.
Patients who undergo split-thickness skin grafting (STSG) are often immobilized post-operatively for graft protection. Restricting mobility following a STSG is thought to protect against subdermal edema and shear forces, despite limited evidence.
Early range of motion (EROM) has been described previously. Recent practice at our burn center includes EROM following hand STSG to limit unnecessary immobilization. The purpose of this retrospective study was to determine if EROM is safe to perform after hand STSG and if there is any clinical benefit.
Methods
In an approved, retrospective, matched case-control study of adult patients who sustained hand burns, patients who received EROM were defined as cases; patients who did not receive EROM were considered controls and received the standard 3–5 days of post-operative immobilization in a resting hand splint. Adult patients admitted over a 3-year period were eligible for inclusion. Patients were evaluated for graft loss and range of motion.
Results
Seventy-two patients were included in this study; 37 EROM patients and 35 matched controls. EROM patients tended to have a larger area excised (170.4 ± 69.8cm2 vs. 132.9 ± 76.2cm2; p=0.034) and grafted (171 ± 70.8 cm2 vs. 132.9 ± 76.2 cm2; p=0.033).
Most patients were male, with an average age of 39 years. Patients had an average of approximately 5% TBSA burns with 1.5% to the hands. On post-op day (POD) 1 and 2, patients received EROM for an average of 30 minutes (29.25 ± 14.9 vs. 31 ± 16.4 minutes).
Six patients experienced minor graft loss. Three patients (8%) experienced graft loss not attributable to EROM. One patient (2.7%) experienced graft loss pre-EROM on POD2 and 3 patients (8%) experienced graft loss post-EROM on either POD1 or POD2. All graft loss was less than 1 cm in greatest dimension and no patient who experienced graft loss required additional surgery as they all closed by their first outpatient follow-up. Significantly more patients who received EROM achieved full digital flexion by the first outpatient visit (25/27=92.6% vs. 15/22=68.2%; p=0.028).
Conclusions
Performing EROM does not cause an increase in graft loss. All areas of graft loss from the EROM group healed without intervention. There appears to be a benefit to EROM since there was a significant improvement in the patients’ ability to make a full fist at initial outpatient follow up. Further prospective analysis is needed to examine the true clinical utility of EROM in the hand and other contracture-prone areas.
Applicability of Research to Practice
Clinical change in post-operative management after hand grafting.
