RESUMO
OBJECTIVES: The increasing frequency of extreme heat events has led to a growing number of heat-related injuries and illnesses in ICUs. The objective of this review was to summarize and critically appraise evidence for the management of heat-related illnesses and injuries for critical care multiprofessionals. DATA SOURCES: Ovid Medline, Embase, Cochrane Clinical Trials Register, Cumulative Index to Nursing and Allied Health Literature, and ClinicalTrials.gov databases were searched from inception through August 2023 for studies reporting on heat-related injury and illness in the setting of the ICU. STUDY SELECTION: English-language systematic reviews, narrative reviews, meta-analyses, randomized clinical trials, and observational studies were prioritized for review. Bibliographies from retrieved articles were scanned for articles that may have been missed. DATA EXTRACTION: Data regarding study methodology, patient population, management strategy, and clinical outcomes were qualitatively assessed. DATA SYNTHESIS: Several risk factors and prognostic indicators for patients diagnosed with heat-related illness and injury have been identified and reported in the literature. Effective management of these patients has included various cooling methods and fluid replenishment. Drug therapy is not effective. Multiple organ dysfunction, neurologic injury, and disseminated intravascular coagulation are common complications of heat stroke and must be managed accordingly. Burn injury from contact with hot surfaces or pavement can occur, requiring careful evaluation and possible excision and grafting in severe cases. CONCLUSIONS: The prevalence of heat-related illness and injury is increasing, and rapid initiation of appropriate therapies is necessary to optimize outcomes. Additional research is needed to identify effective methods and strategies to achieve rapid cooling, the role of immunomodulators and anticoagulant medications, the use of biomarkers to identify organ failure, and the role of artificial intelligence and precision medicine.

INTRODUCTION: Literature examining the connection between obesity and burn injuries is limited. This study is a secondary analysis of a multicenter trial data set to investigate the association between burn outcomes and obesity following severe burn injury. MATERIALS AND METHODS: Body mass index (BMI) was used to stratify patients as normal weight (NW; BMI 18.5-25), all obese (AO; any BMI>30), obese I (OI; BMI 30-34.9), obese II (OII; BMI 35-39.9), or obese III (OIII; BMI>40). The primary outcome examined was mortality. Secondary outcomes included hospital length of stay (LOS), number of transfusions, injury scores, infection occurrences, number of operations, ventilator days, intensive care unit LOS, and days to wound healing. RESULTS: Of 335 patients included for study, 130 were obese. Median total body surface area (TBSA) was 31%, 77 patients (23%) had inhalation injury and 41 patients died. Inhalation injury was higher in OIII than NW (42.1% versus 20%, P = 0.03). Blood stream infections (BSI) were higher in OI versus NW (0.72 versus 0.33, P = 0.03). Total operations, ventilator days, days to wound healing, multiorgan dysfunction score, Acute Physiology and Chronic Health Evaluationscore, hospital LOS, and intensive care unit LOS were not significantly affected by BMI classification. Mortality was not significantly different between obesity groups. Kaplan-Meier survival curves did not significantly differ between the groups (χ2 = 0.025, P = 0.87). Multiple logistic regression identified age, TBSA, and full thickness burn as significant independent predictors (P < 0.05) of mortality; however, BMI classification itself was not predictive of mortality. CONCLUSIONS: No significant association between obesity and mortality was seen after burn injury. Age, TBSA, and percent full- thickness burn were independent predictors of mortality after burn injury, while BMI classification was not.

PURPOSE OF REVIEW: Recently published initiatives spanning the burn care spectrum have substantially changed the standard of care in burn care. The purpose of this article is to describe new impactful concepts in burn first aid, triage, resuscitation, and treatment as well as their impact on future research. RECENT FINDINGS: First aid after burn injury traditionally consists of extinguishing the burn and applying dressings. Recent evidence suggests that applying 20 min of cool tap water to the burn wound in the first 3âh postburn mitigates burn injury extent. National burn center transfer criteria have been updated, impacting patient initial transfer and management. The adverse effects of hydroxocobalamin, a commonly used antidote for cyanide toxicity, have been delineated. Initial burn resuscitation recommendations for both volume and potentially fluid type are being reexamined. The emergence of innovative skin substitutes may improve burn survival by providing a physiologically stabilizing intermediate dressing. Finally, formal clinical practice guidelines for early mobility in the ICU after burn injury have been defined. SUMMARY: These changes in burn care, triage, resuscitation, and treatment have challenged traditional burn care standards, created new standards, and are the basis for future prospective randomized trials.

PURPOSE OF REVIEW: Patients with severe burn injuries pose significant challenges for the intensivist. Though average burn sizes have decreased over time, severe burn injuries involving greater than 20% of the total body surface area still occur. Verified burn centers are limited, making the management of severely burn injured patients at nonspecialized ICUs likely. Current practices in burn care have increased survivability even from massive burns. It is important for intensivists to be aware of the unique complications and therapeutic options in burn critical care management. This review critically discusses current practices and recently published data regarding the evaluation and management of severe burn injury. RECENT FINDINGS: Burn patients have long, complex ICU stays with accompanying multiorgan dysfunction. Recent advances in burn intensive care have focused on acute respiratory distress syndrome from inhalation injury, acute kidney injury (AKI), and transfusion, resulting in new strategies for organ failure, including renal replacement therapy and extracorporeal life support. SUMMARY: Initial evaluation and treatment of acute severe burn injury remains an ongoing area of study. This manuscript reviews current practices and considerations in the acute management of the severely burn injured patient.

PURPOSE OF REVIEW: Blood transfusion is ubiquitous in major burn injury. The present article describes recent research findings directly impacting blood transfusion strategies in major burn injury both in the operating room and the ICU. RECENT FINDINGS: Transfusion strategies have been the focus of recent burn investigations. First, a randomized prospective trial encompassing both the ICU and operating room reported that a restrictive red blood cell transfusion threshold (7âg/dl) had equivalent outcomes to a traditional threshold (10âg/dl) for burns more than 20% in terms of mortality, infection, length of stay, duration of mechanical ventilation, and wound healing despite receiving significantly fewer transfusions. The second burn transfusion advance addresses coagulation. Although burn patients initially have elevated fibrinogen, thrombocytopenia and other coagulation disorders develop during excision. Blood product repletion should be based on measurements such as thromboelastography in addition to traditional tests. Finally, a recent randomized trial suggests that fresh-frozen plasma and platelets during burn excision more than 20% may decrease transfusion requirements. SUMMARY: A restrictive transfusion practice during burn excision and grafting is well tolerated and effective in reducing the number of transfusions without increasing complications. Repletion of coagulation products should focus on measured deficits of platelets, fibrinogen, and factors.

OBJECTIVES: Major trials examining storage age of blood transfused to critically ill patients administered relatively few blood transfusions. We sought to determine if the storage age of blood affects outcomes when very large amounts of blood are transfused. DESIGN: A secondary analysis of the multicenter randomized Transfusion Requirement in Burn Care Evaluation study which compared restrictive and liberal transfusion strategies. SETTING: Eighteen tertiary-care burn centers. PATIENTS: Transfusion Requirement in Burn Care Evaluation evaluated 345 adults with burns greater than or equal to 20% of the body surface area. We included only the 303 patients that received blood transfusions. INTERVENTIONS: The storage ages of all transfused red cell units were collected during Transfusion Requirement in Burn Care Evaluation. A priori measures of storage age were the the mean storage age of all transfused blood and the proportion of all transfused blood considered very old (stored ≥ 35 d). MEASUREMENTS AND MAIN RESULTS: The primary outcome was the severity of multiple organ dysfunction. Secondary outcomes included time to wound healing, the duration of mechanical ventilation, and in-hospital mortality. There were 6,786 red cell transfusions with a mean (± SD) storage age of 25.6 ± 10.2 days. Participants received a mean of 23.4 ± 31.2 blood transfusions (range, 1-219) and a mean of 5.3 ± 10.7 units of very old blood. Neither mean storage age nor proportion of very old blood had any influence on multiple organ dysfunction severity, time to wound healing, or mortality. Duration of ventilation was significantly predicted by both mean blood storage age and the proportion of very old blood, but this was of questionable clinical relevance given extreme variability in duration of ventilation (adjusted r ≤ 0.01). CONCLUSIONS: Despite massive blood transfusion, including very old blood, the duration of red cell storage did not influence outcome in burn patients. Provision of the oldest blood first by Blood Banks is rational, even for massive transfusion.

OBJECTIVE: Our objective was to compare outcomes of a restrictive to a liberal red cell transfusion strategy in 20% or more total body surface area (TBSA) burn patients. We hypothesized that the restrictive group would have less blood stream infection (BSI), organ dysfunction, and mortality. BACKGROUND: Patients with major burns have major (>1 blood volume) transfusion requirements. Studies suggest that a restrictive blood transfusion strategy is equivalent to a liberal strategy. However, major burn injury is precluded from these studies. The optimal transfusion strategy in major burn injury is thus needed but remains unknown. METHODS: This prospective randomized multicenter trial block randomized patients to a restrictive (hemoglobin 7-8âg/dL) or liberal (hemoglobin 10-11âg/dL) transfusion strategy throughout hospitalization. Data collected included demographics, infections, transfusions, and outcomes. RESULTS: Eighteen burn centers enrolled 345 patients with 20% or more TBSA burn similar in age, TBSA burn, and inhalation injury. A total of 7054 units blood were transfused. The restrictive group received fewer blood transfusions: mean 20.3â±â32.7 units, median = 8 (interquartile range: 3, 24) versus mean 31.8â±â44.3 units, median = 16 (interquartile range: 7, 40) in the liberal group (P < 0.0001, Wilcoxon rank sum). BSI incidence, organ dysfunction, ventilator days, and time to wound healing (P > 0.05) were similar. In addition, there was no 30-day mortality difference: 9.5% restrictive versus 8.5% liberal (P = 0.892, χ test). CONCLUSIONS: A restrictive transfusion strategy halved blood product utilization. Although the restrictive strategy did not decrease BSI, mortality, or organ dysfunction in major burn injury, these outcomes were no worse than the liberal strategy (Clinicaltrials.gov identifier NCT01079247).

OBJECTIVES: The goal of this study was to retrospectively evaluate the clinical impact of an accurate autocorrecting blood glucose monitoring system in children with severe burns. Blood glucose monitoring system accuracy is essential for providing appropriate intensive insulin therapy and achieving tight glycemic control in critically ill patients. Unfortunately, few comparison studies have been performed to evaluate the clinical impact of accurate blood glucose monitoring system monitoring in the high-risk pediatric burn population. DESIGN: Retrospective analysis of an electronic health record system. SETTING: Pediatric burn ICU at an academic medical center. PATIENTS: Children (aged < 18 yr) with severe burns (≥ 20% total body surface area) receiving intensive insulin therapy guided by either a noncorrecting (blood glucose monitoring system-1) or an autocorrecting blood glucose monitoring system (blood glucose monitoring system-2). MEASUREMENTS AND MAIN RESULTS: Patient demographics, insulin rates, and blood glucose monitoring system measurements were collected. The frequency of hypoglycemia and glycemic variability was compared between the two blood glucose monitoring system groups. A total of 122 patient charts from 2001 to 2014 were reviewed. Sixty-three patients received intensive insulin therapy using blood glucose monitoring system-1 and 59 via blood glucose monitoring system-2. Patient demographics were similar between the two groups. Mean insulin infusion rates (5.1 ± 3.8 U/hr; n = 535 paired measurements vs 2.4 ± 1.3 U/hr; n = 511 paired measurements; p < 0.001), glycemic variability, and frequency of hypoglycemic events (90 vs 12; p < 0.001) were significantly higher in blood glucose monitoring system-1-treated patients. Compared with laboratory measurements, blood glucose monitoring system-2 yielded the most accurate results (mean ± SD bias: -1.7 ± 6.9 mg/dL [-0.09 ± 0.4 mmol/L] vs 7.4 ± 13.5 mg/dL [0.4 ± 0.7 mmol/L]). Blood glucose monitoring system-2 patients achieve glycemic control more quickly (5.7 ± 4.3 vs 13.1 ± 6.9 hr; p< 0.001) and stayed within the target glycemic control range longer compared with blood glucose monitoring system-1 patients (85.2% ± 13.9% vs 57.9% ± 29.1%; p < 0.001). CONCLUSIONS: Accurate autocorrecting blood glucose monitoring system optimizes intensive insulin therapy, improves tight glycemic control, and reduces the risk of hypoglycemia and glycemic variability. The use of an autocorrecting blood glucose monitoring system for intensive insulin therapy may improve glycemic control in severely burned children.

OBJECTIVES: Determine the relationship between the volume of burn admissions and outcomes for children with burns. DESIGN: Retrospective review of the National Burn Repository from 2000-2009 using mixed effect logistic regression modeling. SETTING: Tertiary burn centers in the United States. PATIENTS: All children <18 years of age admitted with burn injury to a burn center submitting data to the National Burn Repository. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 210,683 records in the NBR from 2000-2009, 33,115 records for children ≤ 18 years of age met criteria for analysis; 26,280 had burn sizes smaller than 10%; only 32 of these children died. Volume of children treated varied greatly among facilities. Age, total body surface area burn, inhalation injury, and burn center volume influenced mortality (p < 0.05) An increase in the median yearly admissions of 100 decreased the odds of mortality by approximately 40%. High volume centers (admitting >200 pediatric patients/year) had the lowest mortality when adjusting for age and injury characteristics (p < 0.05). CONCLUSIONS: Higher volume pediatric burn centers had lower mortality, particularly at larger burn sizes. The lower mortality of children a high volume centers could reflect greater experience, resource, and specialized expertise in treating pediatric patients.

Children have an imperative to explore their environment to grow and develop, which puts them at risk for sustaining burn injury. Burn injury remains the third leading cause of injury-related death worldwide. Plastic surgeons, as experts in the evaluation and management of cutaneous injuries, are frequently called upon to evaluate and treat children with burn injuries. This article focuses on the unique physiologic aspects of children and how they impact initial evaluation and management of burn injury. Children are not "little adults," and they have different airway, circulatory, and cutaneous systems. Understanding the signs of potential child abuse is important to avoid further child harm. Finally, recognition of the criteria for referral to a pediatric burn center is important to optimize both short- and long-term outcomes for patients and families.
RESUMO
Sepsis following burn trauma is a global complication with high mortality, with ~60% of burn patient deaths resulting from infectious complications. Sepsis diagnosis is complicated by confounding clinical manifestations of the burn injury, and current biomarkers markers lack the sensitivity and specificity required for prompt treatment. Circulating extracellular vesicles (EVs) from patient liquid biopsy as biomarkers of sepsis due to their release by pathogens from bacterial biofilms and roles in subsequent immune response. This study applies Raman spectroscopy to patient plasma derived EVs for rapid, sensitive, and specific detection of sepsis in burn patients, achieving 97.5% sensitivity and 90.0% specificity. Furthermore, spectral differences between septic and non-septic burn patient EVs could be traced to specific glycoconjugates of bacterial strains associated with sepsis morbidity. This work illustrates the potential application of EVs as biomarkers in clinical burn trauma care, and establishes Raman analysis as a fast, label-free method to specifically identify features of bacterial EVs relevant to infection amongst the host background.
RESUMO
The classical treatment of extensive full-thickness skin loss due to trauma or burns has been the split-thickness skin graft. While split-thickness skin grafts close the wound, they leave patients with visible scars, dry skin, pruritis, pain, pigmentation alterations, and changes in sensation. The optimal replacement for full-thickness skin loss is replacement with intact full-thickness skin. New technologies combined with advances in the understanding of the mechanisms behind wound healing have led to the development of techniques and products that may eventually recapitulate the functions, appearance, and physical properties of normal skin. Autologous homologous skin constructs, minimal functional skin units, and composite bioengineered skin with dermal substitutes all represent potential avenues for full-thickness composite skin development and application in extensive wounds. This article summarizes the progress, state, and future of full-thickness skin regeneration in burn and massive wound patients.

Frailty can increase the risk of dying after suffering a severe injury. The Modified Frailty Index (MFI) was developed by the American College of Surgeons National Surgical Quality Improvement Program to determine the impact of frailty on outcomes. Our aim was to correlate frailty with survival following a burn injury using the 11-item and 5-item MFI. We performed a secondary analysis of the Transfusion Requirement in Burn Care Evaluation (TRIBE) study. Data including, age, gender, medical history, extent and severity of burn injury, inhalation injury and discharge disposition was collected from the TRIBE database. The 11-item MFI (MFI-11) and 5-item MFI (MFI-5) scores were calculated for all patients in the TRIBE database. The TRIBE database included 347 patients. The mean age of subjects was 43 ± 17 years. Mean total body surface area burn (TBSA) was 38 ± 18%, and 23% had inhalation injury. Multivariate logistic regression analysis determined that both MFI-5 (OR 1.86; 95% CI: 1.11-3.11; P-value .02) and MFI-11 (OR 1.83; 95% CI: 1.18-2.8; P-value .007) were independent predictors for mortality. Additionally, MFI-11 scores that are >1 were independently associated with a markedly increased risk of dying after a burn injury (OR 2.91; 95% CI: 1.1-7.7; P-value .03). The MFI can be used to identify vulnerable burn injured patients who are at high risk of dying.

Self-inflicted burns are a relatively uncommon but profound attempt at suicide. Twenty years ago, we first reviewed our experience with self-inflicted burns. With this current study, we sought to determine whether there had been any change in the incidence or outcomes of self-inflicted burns. All burn patients admitted between January 1, 2012, and December 31, 2021, with self-inflicted burns were compared with all other admissions. The frequency of self-inflicted burns and confounding risk factors of patients with self-inflicted burns remained unchanged. A large proportion (87.4 %) of the patients had psychiatric disease. They also had larger burns and higher mortality than accidental burns. Unexpectedly, logistic regression analysis that controlled for age, total percent total body surface area (TBSA) burn, sex, and inhalation injury revealed that those patients with self-inflicted burns had 72 % lower odds of dying than the general population. In conclusion, there has been no improvement in the incidence of self-inflicted burns. They result in very severe injuries, but when age, burn size, gender, and inhalation injury are controlled for, they have at least as good a chance for survival as the general burn population.

Follow-up rates are concerningly low among burn-injured patients. This study investigates the factors associated with low follow-up rates and missed appointments. We hypothesize that patients who are homeless, use illicit substances, and have psychiatric comorbidities will have lower rates of follow-up and more missed appointments. Data from a discharge-planning survey of 281 burn-injured patients discharged from September 2019 to July 2020 were analyzed and matched with patients' electronic medical records for a retrospective chart review. Data collected included general demographics, burn characteristics, hospitalization details, follow-up visits, missed appointments, homeless status, substance use, major psychiatric illness, and survey responses. Data analysis used chi-square, Fisher's exact test, Student's t-test, Wilcoxon rank sum test, and multivariate regression analysis. Overall, 37% of patients had no follow-up in clinic and 46% had one or more missed appointment. On multivariate regression analysis, homeless patients were more likely to never follow-up, odds ratio (OR) = 0.23 (95% confidence interval [CI] = 0.11-0.49), as were patients who anticipated experiencing transportation difficulties, OR = 0.28 (95% CI = 0.15-0.50). Homeless patients were more likely to have missed appointments, OR = 0.23 (95% CI = 0.1-0.54). On univariate analysis, patients with one or more documented major psychiatric illness had lower follow-up rates, with 50.62% having no follow-up (P < .01). Among patients who responded to the survey that they were current drug users, 52% had no follow-up as compared to 28% of patients who responded that they did not use drugs (P < .01).

INTRODUCTION: Approximately 27.5% of adults 65 and older fall each year, over 3 million are treated in an emergency department, and 32 000 die. The American College of Surgeons and its Committee on Trauma (ACSCOT) have urged trauma centers (TCs) to screen for fall risk, but information on the role of TC in this opportunity for prevention is largely unknown. METHODS: A 29-item survey was developed by an ACSCOT Injury Prevention and Control Committee, Older Adult Falls workgroup, and emailed to 1000 trauma directors of the National Trauma Data Bank using Qualtrics. US TCs were surveyed regarding fall prevention, screening, intervention, and hospital discharge practices. Data collected and analyzed included respondent's role, location, population density, state designation or American College of Surgeons (ACS) level, if teaching facility, and patient population. RESULTS: Of the 266 (27%) respondents, 71% of TCs include fall prevention as part of their mission, but only 16% of TCs use fall risk screening tools. There was no significant difference between geographic location or ACS level. The number of prevention resources (F = 31.58, P < .0001) followed by the presence of a formal screening tool (F = 21.47, P < .0001) best predicted the presence of a fall prevention program. CONCLUSION: Older adult falls remain a major injury risk and injury prevention opportunity. The majority of TCs surveyed include prevention of older adult falls as part of their mission, but few incorporate the components of a fall prevention program. Development of best practices and requiring TCs to screen and offer interventions may prevent falls.

Management of critically ill patients requires simultaneous administration of many medications. Treatment for patient comorbidities may lead to drug-drug interactions which decrease drug efficacy or increase adverse reactions. Current practices rely on a one-size-fits-all dosing approach. Pharmacogenetic testing is generally reserved for addressing problems rather than used proactively to optimize care. We hypothesized that burn and surgery patients will have one or more genetic variants in drug metabolizing pathways used by one or more medications administered during the patient's hospitalization. The aim of this study was to determine the frequency of variants with abnormal function in the primary drug pathways and identify which medications may be impacted. Genetic (19 whole exome and 11 whole genome) and medication data from 30 pediatric burn and surgery patients were analyzed to identify pharmacogene-drug associations. Nineteen patients were identified with predicted altered function in one or more of the following genes: CYP2C9, CYP2C19, CYP2D6, and CYP3A4. The majority had decreased function, except for several patients with CYP2C19 rapid or ultrarapid variants. Some drugs administered during hospitalization that rely on these pathways include hydrocodone, oxycodone, methadone, ibuprofen, ketorolac, celecoxib, diazepam, famotidine, diphenhydramine, and glycopyrrolate. Approximately one-third of the patients tested had functionally impactful genotypes in each of the primary drug metabolizing pathways. This study suggests that genetic variants may in part explain the vast variability in drug efficacy and suggests that future pharmacogenetics research may optimize dosing regimens.

Background: Blood product transfusion has historically been utilized after major burn injury in the resuscitative as well as the acute phase. Transfusion has been implicated in infection and immunosuppression in many disease states. Recommendations for blood product transfusion has varied, but several landmark studies have helped define optimal burn transfusion strategies with respect to infection. The purpose of this article is to review the evidence describing the relation between transfusion and infection in burn injury during different phases of burn treatment to identify optimal transfusion strategies and suggest future targets for transfusion research in burns. Methods: This article presents the history, current status, and future research directions related to blood and blood product transfusion in burn injury. Results: Patients with burns are subject to infectious complications resulting from the loss of skin and burn-related immunosuppression. The use of blood in burn treatment has varied during both the resuscitative phase and the acute treatment phase. Whole-blood use in resuscitation was replaced with crystalloid infusion. Future trials are examining the role of plasma and albumin in burn resuscitation. A randomized prospective multicenter transfusion trial was able to decrease transfusion by 50% with no change in infection. Further examination of the role of hemostatic resuscitation in burn excision may help to better define transfusion goals. Conclusions: Blood product transfusion in burn injury has varied throughout the last century. Although advances in the understanding of blood transfusion in burn injury have occurred, initiatives to define optimal care better are required.

In the past ten years wildfires have burned an average of 6.8 million acres per year and this is expected to increase with climate change. Wildfire burn patient outcomes have not been previously well characterized. Wildfire burn patients from the Tubbs or Camp wildfires and non-wildfire burn matched controls were identified from the burn center database and outcomes were compared. The primary outcome was mortality. Secondary outcomes included length of stay (LOS), intensive care unit (ICU) LOS, readmission and development of wound infections. Time of presentation and operating room use after wildfires was evaluated. Sixteen wildfire burn patients were identified and matched with 32 controls. Wildfire burn patients trended towards higher mortality (19% wildfire vs. 9% non-wildfire, p=0.386), longer LOS (18 days wildfire vs. 15 days non-wildfire, p=0.406), longer ICU LOS (17 days wildfire vs. 11 days non-wildfire, p=0.991), increased readmission (19% wildfire vs. 3% non-wildfire, p=0.080) and higher rates of wound infection (31% wildfire vs. 19% non-wildfire, p=0.468). The majority of wildfire patients (88%) presented within 24 hours of the wildfire reaching a residential area. Operating room time within the first week was 13 hours 44 minutes for the Tubbs Fire and 19 hours 1 minute for the Camp Fire. Patients who sustain burns in wildfires are potentially at increased risk of mortality, prolonged LOS, wound infection and readmission.
