Abstract Burn damage can lead to a state of immune dysregulation that facilitates the development of infections in patients. The most deleterious impact of this dysfunction is the loss of the skin’s natural protective barrier. Furthermore, the risk of infection is exacerbated by protracted hospitalization, urinary catheters, endotracheal intubation, inhalation injury, arterial lines and central venous access, among other mainstays of burn care. Currently, infections comprise the leading cause of mortality after major burn injuries, which highlights the improvements observed over the last 50 years in the care provided to burn victims. The need to implement the empirical selection of antibiotic therapy to treat multidrug-resistant bacteria may concomitantly lead to an overall pervasiveness of difficult-to-treat pathogens in burn centres, as well as the propagation of antimicrobial resistance and the ultimate dysregulation of a healthy microbiome. While preliminary studies are examining the variability and evolution of human and mice microbiota, both during the early and late phase burn injury, one must consider that abnormal microbiome conditions could influence the systemic inflammatory response. A better understanding of the changes in the post-burn microbiome might be useful to interpret the provenance and subsequent development of infections, as well as to come up with inferences on the prognosis of burn patients. This review aims to summarise the current findings describing the microbiological changes in different organs and systems of burn patients and how these alterations affect the risks of infections, complications, and, ultimately, healing.

Respiratory compromise is a recognised sequelae of major burn injuries, and in rare instances requires extracorporeal membrane oxygenation (ECMO). Over a ten-year period, our hospital trust, an ECMO centre and burns facility, had five major burn patients requiring ECMO, whose burn injuries would normally be managed at trusts with higher levels of burn care. Three patients (60%) survived to hospital discharge, one (20%) died at our trust, and one patient died after repatriation. All patients required regular, time-intensive dressing changes from our specialist nursing team, beyond their regular duties. This review presents these patients, as well as a review of the literature on the use of ECMO in burn injury patients. A formal review of the overlap between the networks that cater to ECMO and burn patients is recommended.

Abstract Patients with major burn injuries typically require numerous blood transfusions. It is not known if an inhalation injury (INHI) directly influences the need for blood transfusion. The purpose of this study was to determine whether INHI increases the amount of blood transfused to major burn patients. A secondary analysis from the Transfusion Requirement in Burn Care Evaluation (TRIBE) study was conducted. Patients with INHI were compared with patients without INHI. The number of red blood cell (RBC) transfusions per day (RBC per day) between INHI and No INHI was analyzed with a multivariable regression. Patients with INHI (n = 78) had significantly larger burns (P = .0004), larger full-thickness burns (P = .0007), greater admission APACHE score (P < .0001), higher admission multiple organ dysfunction scores (P < .0001), and were transfused more RBC per day (P = .009) than No INHI patients (n = 267). In the multivariable regression analysis, RBC per day was significantly associated with the %TBSA burn (P < .0001), age of the patient (P = .004), the need for more than 1 day of mechanical ventilation (P < .0001), the occurrence of at least one blood stream infection (BSI; P = .044), and being assigned to the liberal transfusion arm of TRIBE (P < .001) but not the presence of INHI (P = .056). The null hypothesis that INHI exerts no influence on the amount of blood transfused could not be rejected. Larger burn size, advanced patient age, mechanical ventilation, and BSIs are important determinants of the blood transfusion rate in major burn patients.

Abstract Introduction In burn patients, vitamin D deficiency has been associated with increased incidence of sepsis. The objective of this study was to assess the impact of vitamin D deficiency in adult burn patients on hospital length of stay (LOS). Methods This was a multi-center retrospective study of adult patients at 7 burn centers admitted between January 1, 2016 and July 25, 2019 who had a 25-hydroxyvitamin D (25OHD) concentration drawn within the first 7 days of injury. Patients were excluded if admitted for a non-burn injury, total body surface area (TBSA) burn less than 5%, pregnant, incarcerated, or made comfort care or expired within 48 hours of admission. The primary endpoint was to compare hospital LOS between burn patients with vitamin D deficiency (defined as 25OHD &lt; 20 ng/mL) and sufficiency (25OHD ≥ 20 ng/mL). Secondary endpoints include in-hospital mortality, ventilator-free days of the first 28, renal replacement therapy (RRT), length of ICU stay, and days requiring vasopressors. Additional data collected included demographics, Charlson Comorbidity Index, injury characteristics, form of vitamin D received (ergocalciferol or cholecalciferol) and dosing during admission, timing of vitamin D initiation, and form of nutrition provided. Dichotomous variables were compared via Chi-square test. Continuous data were compared via student t-test or Mann-Whitney U test. Univariable linear regression was utilized to identify variables associated with LOS (p &lt; 0.05) to analyze further. Cox Proportional Hazard Model was utilized to analyze association with LOS, while censoring for death, and controlling for TBSA, age, presence of inhalation injury, and potential for a center effect. Results Of 1,147 patients screened, 412 were included. Fifty-seven percent were vitamin D deficient. Patients with vitamin D deficiency had longer LOS (18.0 vs 12.0 days, p &lt; 0.001), acute kidney injury (AKI) requiring RRT (7.3 vs 1.7%, p = 0.009), more days requiring vasopressors (mean 1.24 vs 0.58 days, p = 0.008), and fewer ventilator free days of the first 28 days (mean 22.9 vs 25.1, p &lt; 0.001). Univariable analysis identified burn center, AKI, TBSA, inhalation injury, admission concentration, days until concentration drawn, days until initiating supplementation, and dose as significantly associated with LOS. After controlling for center, TBSA, age, and inhalation injury, the best fit model included only deficiency and days until vitamin D initiation. Conclusions Patients with thermal injuries and vitamin D deficiency on admission have increased length of stay and worsened clinical outcomes as compared to patients with sufficient vitamin D concentrations.

Background Acute kidney injury (AKI) is one of the most severe complications of burn injury. AKI with severe burn injury causes high mortality. This study aims to investigate the incidence of and predisposing factors for AKI in burn patients. Methods This is a single-center, retrospective, descriptive criterion standard study conducted from June 27, 2015, to March 8, 2016. We used Kidney Disease Improving Global Outcomes criteria to define and select patients with AKI. The study was conducted by recruiting in hospital patients who suffered from the flammable cornstarch-based powder explosion and were treated under primary care procedures. A total of 49 patients who suffered from flammable dust explosion-related burn injury were enrolled and admitted on June 27, 2015. The patients with more than 20% total body surface area of burn were transferred to the intensive care unit. Patients received fluid resuscitation in the first 24 hours based on the Parkland formula. The primary measurements were the incidence of and predisposing factors for AKI in these patients. Demographic characteristics, laboratory data, and inpatient outcomes were also evaluated. The incidence of AKI in this cohort was 61.2% (n = 30). The mortality rate was 2.0% (n = 1) during a 59-day follow-up period. The multivariate analysis revealed inhalation injury (adjusted OR = 22.0; 95% CI [1.4–358.2]) and meeting ≥3 American Burn Association (ABA) sepsis criteria (adjusted OR = 13.7; 95% CI [1.7–110.5]) as independent risk factors for early advanced AKI. Conclusions The incidence rate of AKI was higher in this cohort than in previous studies, possibly due to the flammable dust explosion-related burn injury. However, the mortality was lower than that expected. In clinical practice, indicators of inflammation, including ABA sepsis criteria may help in predicting the risk of AKI in patients with burn injury.

Abstract Introduction Endotheliopathy in burn patients is largely uncharacterized. Syndecan-1 (SDC-1), thrombomodulin (TM), and tissue factor pathway inhibitor (TFPI) are components of the vascular endothelial glycocalyx. Proteolytic cleavage of these moieties may yield biomarkers for endothelial damage. The aim of this study is to evaluate endotheliopathy after burn injury by monitoring plasma levels of these biomarkers over time to investigate potential relationship to mortality. Methods Burn injured patients presenting to a regional burn center from 2012 to 2017 were prospectively enrolled. Blood samples were collected at 0, 2, 4, 8, 12, 24, 36, 48, 60, and 72 hours from admission. Plasma SDC-1, TM, and TFPI levels were quantified by ELISA. Demographic data and injury characteristics were obtained from the medical chart. Patients with concomitant inhalation injury, trauma, or &lt; 10% total body surface area (TBSA) burns were excluded. Statistical analysis was performed using mixed-effect models with Sidak’s correction for multiple comparisons. Significance was set at p =0.05. Data are presented as mean ± standard deviation. Results A cohort of 22 patients was identified with an average age of 45±14 years, TBSA of 30±15%, with 6 patients who died from their injuries. The deceased group was older (59±13 vs. 40±10 years, p = 0.01), and there was no significant difference in burn size. Mean SDC-1 levels were higher in the deceased group at all time points (p=0.0004) and this difference was significant at hour 12 (106±11 vs. 41±31 ng/mL, p = 0.0002), hour 24 (160±39 vs. 35±20 ng/mL, p = 0.04) and hour 72 (100±3 vs. 35±38 ng/mL, p = 0.01). Mean soluble TM levels were higher in the deceased group after hour 12 (p = 0.04) and there was a trend towards higher TFPI levels after hour 12 in the deceased group. Conclusions Biomarkers are elevated in patients following burn injury who die, when inhalation injury and trauma are excluded. Given equivalent TBSA, older patients appear more sensitive to thermally induced glycocalyx degradation. SDC-1 shows the greatest promise as a prognostic indicator as levels tend to be higher among deceased patients on admission and are significantly higher as early as hour 12. Applicability of Research to Practice Reliable assessment of the patient’s endothelial damage may hold predictive value for clinicians and could assist in clinical decision making. Further research must investigate endotheliopathy in burn patients.

Abstract Introduction Climate change, the encroachment of populations into wilderness, and carelessness have combined to increase the incidence of wildfire injuries. With the increased incidence has come an increase in the number of burn injuries. Prolonged extrication, delays in resuscitation, and the extreme fire and toxic air environment in a wildfire has the potential to cause more severe burn injury. The purpose of this study is to examine the demographics and outcomes of wildfire injuries and compare those outcomes to non-wildfire injuries. Methods Charts of patients admitted to a regional burn center during a massive wildfire in 2018 were reviewed for demographic, treatment, and outcome. We then obtained age, gender, and burn size matched controls from within 2 years of the incident, analyzed the same measures, and compared treatment and outcomes between the two groups. Results A total of 20 patients, 10 wildfire (WF) burns and 10 non-wildfire (NWF) burns, were included in the study. Age (59.6±7.8 WF vs. 59.4±7.4 years), total body surface area burn (TBSA) (14.9±4.7 WF vs. 17.2±0.9 NWF) and inhalation injury incidence (2 WF and 2 NWF) were similar between groups. Days on mechanical ventilation (24.3±19.4 WF vs. 9.4±9.8 NWF), length of stay (49.9±21.8 WF vs. 28.2±11.7 days) and ICU length of stay (43.0±25.6 WF vs 24.4±11.2 NWF) were higher in the WF group. WF patients required twice the number of operations. Mortality was similar in both groups (1 death/group). Conclusions Wildfire burn injuries, when compared to age, inhalation injury, and burn size matched controls, require more ventilatory support and have more operations. As a result, they have longer lengths of stay and have a prolonged ICU course. Burn centers should be prepared for the increased resource utilization that accompanies wildfire injuries. Applicability of Research to Practice All burn centers must be prepared for the possibility of wildfires and the increased resource utilzation that accompanies mass casualty events.

Abstract Introduction As the population ages; burn centers, especially those with a large rural catchment, will be expected to care for older adults with complex medical co-morbidities. Recent work has shown that %TBSA at which 50% of patients would be expected to die (LD50) for elderly patients is up to 20% lower than non-elderly patients. However, the factors contributing to mortality are unclear. We undertook this study to characterize our experience with elderly burn patients in our rural state and to understand how mortality is affected by comorbid disease. Methods We performed a retrospective review of all burn patients ≥50 years old admitted to our burn center over a 5 year period between January 2014 and December 2018. We collected demographic and injury data including %TBSA, mechanism, inhalation injury status, discharge disposition, length of stay as well as complications including pneumonia, kidney injury, wound infection and graft loss. We calculated the modified Baux score, Charlson Comorbidity Index (CCI) and overall mortality for each patient. The %TBSA and CCI were correlated with complications and mortality using the Pearson correlation coefficient analysis. Results There were 243 patients (35%) who met inclusion criteria out of total of 688 burn admissions during that period. The median age was 60 years (mean 62.2, range: 50–95) and 72.4% were male. The median TBSA was 4% (mean: 8.2%, range: 0.5% - 55%). We found weak correlations between CCI and both pneumonia (R=0.177, p=0.005) and mortality (R=0.1297, p=0.0434). There was also a weak correlation between %TBSA and pneumonia (R=0.3302, p &lt; 0.001), kidney injury (R=0.205, p=0.001), wound infection (R=0.1295, p=0.045) and graft loss (R=0.2616, p&lt; 0.001). Interestingly, in the subgroup with &gt; 15% TBSA burns (n=35), there was no significant correlation with increased complications. For the entire cohort, the predicted mortality based on the mean modified Baux score was 16%. The actual observed mortality was 4.1%. Conclusions Our findings suggest that, in our center, CCI is not predictive of burn related complications or mortality and %TBSA is not predictive of complications or death. The observed to expected mortality ratio was remarkably low. Applicability of Research to Practice As we treat older burn patients, it is important to identify the individual patient factors and hospital specific burn care factors that may improve outcomes in the elderly population.

Background: Pulmonary hypercoagulopathy is intrinsic to inhalation trauma. Nebulized heparin could theoretically be beneficial in patients with inhalation injury, but current data are conflicting. We aimed to investigate the safety, feasibility, and effectiveness of nebulized heparin. Methods: International multicenter, double-blind, placebo-controlled randomized clinical trial in specialized burn care centers. Adult patients with inhalation trauma received nebulizations of unfractionated heparin (25,000 international unit (IU), 5 mL) or placebo (0.9% NaCl, 5 mL) every four hours for 14 days or until extubation. The primary outcome was the number of ventilator-free days at day 28 post-admission. Here, we report on the secondary outcomes related to safety and feasibility. Results: The study was prematurely stopped after inclusion of 13 patients (heparin N = 7, placebo N = 6) due to low recruitment and high costs associated with the trial medication. Therefore, no analyses on effectiveness were performed. In the heparin group, serious respiratory problems occurred due to saturation of the expiratory filter following nebulizations. In total, 129 out of 427 scheduled nebulizations were withheld in the heparin group (in 3 patients) and 45 out of 299 scheduled nebulizations were withheld in the placebo group (in 2 patients). Blood-stained sputum or expected increased bleeding risks were the most frequent reasons to withhold nebulizations. Conclusion: In this prematurely stopped trial, we encountered important safety and feasibility issues related to frequent heparin nebulizations in burn patients with inhalation trauma. This should be taken into account when heparin nebulizations are considered in these patients.

Optimal care of the burn patient requires not only specialized equipment but also, more importantly, a team of dedicated surgeons, nurses, therapists, nutritionists, pharmacists, social workers, psychologists, and operating room staff. Burn care was one of the first specialties to adopt a multidisciplinary approach, and over the past 30 years, burn centers have decreased burn mortality by coordinating prehospital patient management, resuscitation methods, and surgical and critical care of patients with major burns. This review covers where to treat burn patients, fluid management, airway management, temperature regulation, airway control, nutrition, anemia, pain management, deep vein thrombosis prophylaxis, and putting it all together: an algorithmic approach to early care of the burn-injured patient. Figures show that the size of a burn can be estimated by means of the Rule of Nines, which assigns percentages of total body surface to the head, the extremities, and the front and back of the torso, the approach to the burn patient in the first 24 hours, and the approach to the burn patient during the second to fifth days after burn injury. Tables list American Burn Association criteria for burn injuries that warrant referral to a burn unit, criteria for outpatient management of burn patients, acute physiologic changes during burn resuscitation, acute biochemical and hematologic changes during burn resuscitation, measures of pulmonary function, mechanisms of pulmonary dysfunction and indications for mechanical ventilation, clinical manifestations of carbon monoxide poisoning, half-life of carbon monoxide–hemoglobin bonds with inhalation therapy, increased acute kidney injury in patients treated with hydroxocobalamin for suspected inhalation injury, clinical findings associated with specific inhaled products of combustion, bronchoscopic criteria used to grade inhalation injury, and formulas for estimating caloric needs in burn patients.
