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 Prior studies of burn patients with &lt; 20% total body surface area (TBSA) burns have found that 15.4% of patients have major psychiatric illness (MPI) and 27.6% have Substance Use Disorder (SUD). In patients with small burns, SUD is associated with larger burn size and secondarily with longer length of stay while MPI is associated with longer lengths of stay while not increasing burn size. The purpose of this study was to determine whether MPI or SUD dependence affects outcomes such as mortality in patients with major burn injuries (≥20% TBSA). Methods A secondary analysis from the prospective, randomized, multicenter Transfusion Requirement in Burn Care Evaluation (TRIBE) study was conducted. Patients with MPI and SUD were compared with patients without these disorders. Statistical analysis with chi-square for categorical variables and student’s t-test for continuous variables was conducted. Mortality between those with and without MPI and SUD were analyzed with a multivariable regression analysis. Results A total of 347 patients with a mean age of 43±17 years, 274 men and 73 women, were analyzed. The mean total body surface area burn (TBSA) was 38±18%, and 23% had inhalation injury. In this study population, 29.1% had SUD, 7.5% had MPI, and 2.3% had both. There was no difference with respect to age, gender, TBSA, frailty, or assignment to the liberal or restrictive transfusion strategy based on the presence of MPI, SUD, or both. Inhalation injury was more common in patients with MPI (27%) or SUD (35%) when compared with patients without these comorbidities (18%) or those who have both (11%) (p=0.006). Patients with MPI were more likely to die of their burn injuries (27%) when compared with those with SUD (17%), both (11%), or neither (8%) (p=0.014). On multivariate analysis for mortality controlling for TBSA and inhalation injury, MPI was found to be an independent predictor of death with an odds ratio of 5 (95% confidence interval 1.7–15, p=0.003). Conclusions In burns &gt;20% TBSA, both MPI and SUD influence patient’s likelihood of sustaining inhalation injury. MPI is also independently associated with mortality in the study. Further work must be done to mitigate the effects of mental illness on burn outcomes.

Abstract Introduction Previous studies in the burn population have noted frailty as an independent predictor of inpatient and outpatient mortality. The Modified Frailty Index (MFI) uses comorbidities tracked by the American College of Surgeons National Surgical Quality Improvement Program to help to predict morbidity and mortality in patients. The purpose of this study was to determine whether or not the MFI-5 and MFI-11 would predict mortality in the burn population. Methods A secondary analysis of the prospective, randomized, multicenter Transfusion Requirement in Burn Care Evaluation (TRIBE) study was conducted. Statistical analysis with chi-square for categorical variables and student’s t-test for continuous variables were conducted. Frailty was determined using the MFI-5 (functionally dependent, diabetes mellitus, chronic obstructive pulmonary disease, congestive heart failure, hypertension) and MFI-11 (using the aforementioned 5, as well as myocardial infarction, hypertension, delirium, transient ischemic attack/cerebrovascular accident (without deficits), cerebrovascular accident (with deficits), peripheral vascular disease) from comorbidities included in the Burn Registry. Patients were considered frail if they had an MFI &gt; 1 on either scale. Multivariate regression was used to compare mortality between those who were and those were not considered frail based on this index. Results A total of 347 patients with a mean age of 43±17 years, 73 women and 274 men, were analyzed. Mean total body surface area burn (TBSA) was 38±18%, and 23% had inhalation injury. As continuous variables, MFI-5 (OR 1.86; 95% CI 1.11–3.11; p-value 0.02) and MFI-11 (OR 1.83; 95% CI 1.18–2.8; p-value 0.007) were independent predictors of mortality. In addition, TBSA total, age, and female gender were all independent predictors of mortality. Having a MFI-11 &gt; 1 was considered an independent predictor of mortality (OR 2.91; 95% CI 1.1–7.7; p-value 0.03); whereas, having a MFI-5 &gt; 1 was not considered an independent predictor of mortality (OR 2.6; 95% CI 0.95–7; p-value 0.06). Conclusions A MFI-11 &gt; 1 in the burn population was an independent predictor of mortality, as were total TBSA, age, and female gender. Given these findings, further study on the predictive value of MFI-11 in major burn injury is warranted.

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.

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.

Restrictive Transfusion Strategy

Abstract Introduction Many burn centers use a restrictive blood transfusion strategy based on randomized controlled trials in burn patients (e.g. Transfusion Requirements in Burn Care Evaluation -TRIBE) and non-burn populations (e.g. Transfusion Requirements in Critical Care – TRICC), which have demonstrated no increased morbidity or mortality between restrictive and liberal transfusion approaches. The purpose of this study was to evaluate the adherence to a restrictive hemoglobin transfusion trigger strategy of 7 g/dL. Methods Retrospective study of all patients admitted to an adult regional ABA-verified burn centre between 15/11/ 2015 and 15/6/2018 who received at least one unit of blood (RBC). We use a restrictive transfusion strategy that administers RBC for a hemoglobin (HGb) &lt; 7 gm/dL, one unit at a time, with a pre and post HGb level for each RBC transfusion, unless the patient is actively bleeding and/or hemodynamically unstable. RBC transfusions in the operating room do not follow this policy and were not studied. Values are presented as mean ± SD or median (IQR) as appropriate. Results We studied 66 patients (30% female) with age 53.2 ± 18.3 years, % TBSA burn 22 (11–41), % TBSA full thickness burn 6.5 (0.5 -21.8), and with 41% having inhalation injury. Overall, there were 691 RBC transfusions (TXns). A pre-TXn HGb was obtained 95% of the time and was 6.8 (6.5–7) gm/dL. TXn for a HGb &gt; 7 gm/dL occurred in 35%. A post TXn HGb was obtained for 92% of these TXns with a HGb of 7.6 (7.2–8) gm/dL. RBC TXns during nighttime (1700 to 0800, n=449) were given for a HGb trigger of 6.8 (6.4–6.9) and were not compliant with our restrictive strategy 22% of the time. Daytime transfusions (0800 to 1700, n=207) were given for a significantly higher HGb [7 (6.7–7.1), p&lt; 0.001] with significantly more non-compliance with the restrictive strategy (50%, p&lt; 0.001). We also compared TXns before and after the TRIBE publication. Pre-TRIBE TXns (n=484) were given for significantly lower HGb than 172 post TRIBE TXns [6.8 (6.4–7) vs 6.9 (6.6–7.1) gm/dL respectively, p=0.001] and at significantly lower rate of non-compliance with the 7 gm/dL threshold than post TRIBE transfusions (28.1% vs 37.8%, respectively, p=0.02). Conclusions While a pre-TXn HGb level was available for 95% of blood transfusions, approximately one-third were given for a HGb &gt; 7 gm/dL. Transfusion during nighttime (being predominantly ordered by housestaff physicians) were administered at a significantly lower HGb trigger and with significantly better compliance with the restrictive strategy than daytime transfusions. Paradoxically, compliance with the restrictive strategy was worse following the TRIBE publication. Applicability of Research to Practice These results identify important areas for improvement in adherence to our restrictive transfusion strategy.

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.

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.
