Abstract
Pulmonary insufficiency is the primary cause of death in cases of major burns accompanied by inhalation damage. It is important to consider the impact on the face and neck in flame burns. Early implementation of bronchial hygiene measures and oxygenation treatment in inhalation injury can reduce mortality. This case series presents the effects of high-flow nasal oxygen (HFNO) application on patient outcomes in major burns and inhalation injury. This report discusses 3 different patients. One patient, a 29-year-old male with 35% TBSA burns, received HFNO treatment for inhalation injury on the sixth day after the trauma. After 72 hours of HFNO application, the patient's pulmonary symptoms improved. The second patient had 60% TBSA burns and developed respiratory distress symptoms on the fifth day after the trauma. After 7 days of HFNO application, all symptoms and findings of acute respiratory distress syndrome (ARDS) were resolved. HFNO has been used for the treatment of ARDS related to major burn (60% of burned TBSA) in a 28-year-old patient, and improvement was achieved. The use of HFNO in pulmonary insufficiency among burn patients has not been reported previously. This series of patient cases demonstrates the successful application of HFNO in treating inhalation injury and burn-related ARDS. However, further clinical studies are necessary to increase its clinical utilization.

Abstract
Military personnel, firefighters, and fire survivors exhibit a higher prevalence of mental health conditions such as depression and post-traumatic stress disorder (PTSD) compared to the general population. While numerous studies have examined the neurological impacts of physical trauma and psychological stress, research on acute neurobehavioral effects of gas inhalation from explosions or fires is limited. This study investigates the early-stage neurobehavioral and neuronal consequences of acute explosion gas inhalation in Sprague-Dawley rats. Rats were exposed to simulated explosive gas and subsequently assessed using behavioral tests and neurobiological analyses. The high-dose exposure group demonstrated significant depression-like behaviors, including reduced mobility and exploration. However, neuronal damage was not evident in histological analyses. Immunofluorescence revealed increased density of radial glia and oligodendrocytes in specific brain regions, suggesting hypoxia and axon damage induced by gas inhalation as a potential mechanism for the observed neurobehavioral changes. These findings underscore the acute impact of explosion gas inhalation on mental health, highlighting the habenula and dentate gyrus of hippocampus as the possible target regions. The findings are expected to support early diagnosis and treatment strategies for brain injuries caused by explosion gas, offering insights into early intervention for depression and PTSD in affected populations.

Polycyclic aromatic hydrocarbons and their metabolites in bronchoalveolar lavage and urine samples from patients with inhalation injury throughout their hospitalization: A prospective pilot study. PLoS One 2024; 19:e0308163. [PMID: 39088550 PMCID: PMC11293749 DOI: 10.1371/journal.pone.0308163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Accepted: 07/18/2024] [Indexed: 08/03/2024] Open
Abstract
BACKGROUND Specific toxic compounds, such as polycyclic aromatic hydrocarbons (PAHs) and their metabolites, may affect the inhalation injury (INHI) grade, patients' status, and prognosis for recovery. This pilot prospective study aimed to: i) evaluate the suitability of bronchoalveolar lavage (BAL) for determination of PAHs in the LRT and of urine for determination of hydroxylated metabolites (OH-PAHs) in patients with INHI, ii) describe the dynamic changes in the levels of these toxic compounds, and iii) correlate these findings with clinical variables of the patients with INHI. METHODS The BAL and urine samples from 10 patients with INHI were obtained on Days 1, 3, 5, 7, and 14 of hospitalization, if possible, and PAHs (BAL) and OH-PAHs (urine) were analyzed using chromatographic methods (GC-MS and HPLC). RESULTS Concentrations of analyzed PAHs were in most cases and time points below the limit of quantification in BAL samples. Nine OH-PAHs were detected in the urine samples; however, their concentrations sharply decreased within the first three days of the hospitalization. On Day 14, the total amount of OH-PAHs in urine was higher in surviving patients with High-grade INHI (≥3) than in those with Low-grade INHI (<3, p = 0.032). Finally, a significant correlation between certain OH-PAHs and clinical variables (AST/ALT, TBSA, ABSI) from Day 1 of the hospitalization was observed (p<0.05). CONCLUSIONS BAL samples are not suitable for the analysis of PAHs. However, the OH-PAHs levels in urine can be measured reliably and were correlated with several clinical variables. Moreover, High-grade INHI was associated with higher total concentrations of OH-PAHs in urine.

Abstract
INTRODUCTION Burns are tissue traumas caused by energy transfer and occur with a variable inflammatory response. The consequences of burns represent a public health problem worldwide. Inhalation injury (II) is a severity factor when associated with burn, leading to a worse prognosis. Its treatment is complex and often involves invasive mechanical ventilation (IMV). The primary purpose of this study will be to assess the evidence regarding the frequency and mortality of II in burn patients. The secondary purposes will be to assess the evidence regarding the association between IIs and respiratory complications (pneumonia, airway obstruction, acute respiratory failure, acute respiratory distress syndrome), need for IMV and complications in other organ systems, and highlight factors associated with IIs in burn patients and prognostic factors associated with acute respiratory failure, need for IMV and mortality of II in burn patients. METHODS This is a systematic literature review and meta-analysis, according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). PubMed/MEDLINE, Embase, LILACS/VHL, Scopus, Web of Science, and CINAHL databases will be consulted without language restrictions and publication date. Studies presenting incomplete data and patients under 19 years of age will be excluded. Data will be synthesized through continuous (mean and standard deviation) and dichotomous (relative risk) variables and the total number of participants. The means, sample sizes, standard deviations from the mean, and relative risks will be entered into the Review Manager web analysis software (The Cochrane Collaboration). DISCUSSION Despite the extensive experience managing IIs in burn patients, they still represent an important cause of morbidity and mortality. Diagnosis and accurate measurement of its damage are complex, and therapies are essentially based on supportive measures. Considering the challenge, their impact, and their potential severity, IIs represent a promising area for research, needing further studies to understand and contribute to its better evolution. The protocol of this review is registered on the International prospective register of systematic reviews platform of the Center for Revisions and Disclosure of the University of York, United Kingdom (https://www.crd.york.ac.uk/prospero), under number RD42022343944.

Abstract
Sustaining an inhalation injury increases the risk of severe complications and mortality. Current evidential support to guide treatment of the injury or subsequent complications is lacking, as studies either exclude inhalation injury or design limit inferences that can be made. Conventional ventilator modes are most commonly used, but there is no consensus on optimal strategies. Settings should be customized to patient tolerance and response. Data for pharmacotherapy adjunctive treatments are limited.

Abstract
BACKGROUND The utility of follow-up blood cultures (FUBC) for gram-negative bloodstream infections (BSIs) are controversial due to low rates of positivity. However, recent studies suggest higher rates of positivity in critically ill patients. The utility of FUBC in gram-negative BSI in patients with severe burn injuries is unknown. METHODS Patients ≥ 18 years old admitted to the US Army Institute of Surgical Research Burn Center for combat-related thermal burns from 1/2003-6/2014 with a monomicrobial BSI were included. FUBC were defined as repeat cultures 1-5 days from index BSI. Persistent BSI (pBSI) was defined as isolation of the same organism from initial and FUBC. The primary endpoint was all-cause in-hospital mortality in patients with gram-negative pBSI. RESULTS Of 126 patients meeting inclusion criteria with BSI, 53 (42%) had pBSI. Compared to patients without persistence, patients with pBSI had more severe burns with median total body surface area (TBSA) burns of 47% ([IQR 34-63] vs. 35.3% [IQR 23.3-56.6], p = 0.02), increased mortality (38 vs. 11%, p = 0.001) compared to those with non-persistent BSI. On multivariate analysis, pBSI was associated with an odds ratio for mortality of 5.3 [95% CI 1.8-15.8, p = 0.003). Amongst gram-negative pathogens, persistence rates were high and associated with increased mortality (41% vs. 11%, p = 0.001) compared to patients without pBSI. CONCLUSION In this cohort of military patients with combat-related severe burns, pBSI was more common than in other hospitalized populations and associated with increased mortality. Given this high frequency of persistence in patients with burn injuries and associated mortality, FUBC are an important diagnostic and prognostic study in this population.

Clin Nutr ESPEN 2024; 59:126-134. [PMID: 38220365 DOI: 10.1016/j.clnesp.2023.11.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 08/03/2023] [Accepted: 11/26/2023] [Indexed: 01/16/2024]
Abstract
BACKGROUND & AIMS Severe burns lead to metabolic changes, systemic inflammatory response syndrome, and multiple organ dysfunction syndrome. Omege-3 polyunsaturated fatty acids (PUFAs) have anti-inflammatory properties. In the absence of substantial evidence for use on major burns, we systematically reviewed the efficacy of omega-3 PUFAs for patients with severe burns. METHODS We comprehensively searched MEDLINE, Web of Science, Embase, Cochrane Library, China National Knowledge Internet, Wang Fang Data, Chinese Biomedicine Database, and Science Direct databases to collect randomised controlled trials of omega-3 PUFAs administered to patients with burns from January 2000 to June 2023. Two researchers independently screened the literatures, extracted the data, and assessed the risk of bias in the included studies. The outcomes were mortality, the risk of severe sepsis, septic shock, and multiple organ dysfunction syndrome. Data synthesis was conducted using Review Manager. Trial sequential analyses (TSA) for outcomes were performed. RESULTS Three randomised controlled trials involving 140 patients were included. Of these, 71 patients received omega-3 PUFAs. The results showed that omega-3 PUFAs significantly reduced the incidence of severe sepsis, septic shock, multiple organ dysfunction syndrome (RR = 0.38, 95 % CI [0.19, 0.75], P = 0.005), C-reactive protein levels (MD = -39.70[-81.63, 2.23], P = 0.06), and improved respiratory outcomes. However, there was no difference in 14-day mortality (RR = 1.10, 95%CI [0.59, 2.05], P = 0.75). TSA showed that the results for the incidence of severe sepsis, septic shock, multiple organ dysfunction syndrome are insufficient and inconclusive. CONCLUSIONS Omega-3 PUFAs may reduce inflammatory response and risk of sepsis, septic shock, and multiple organ dysfunction syndrome in severe burns patients and may shorten hospital stay but cannot reduce risk of death. Due to the limitation of the quantity and quality of the included studies, the evidence level is low, and the conclusions need to be verified by larger scale and higher quality randomised controlled trials.

Abstract
This retrospective study investigated the association of sugammadex with postoperative pulmonary complication risk between 2013 and 2021 in patients with severe burn of five hospitals. Postoperative pulmonary complications included atelectasis, pulmonary edema, pulmonary effusion, pneumothorax, pneumonia, pulmonary thromboembolism, respiratory failure and acute respiratory distress. To identify whether sugammadex reduced the risk of postoperative pulmonary complication in patients with severe burn who underwent surgery, Kaplan-Meier curve were used to check the difference of incidence according to surgical cases and time-varying Cox hazard regression were used to calculate the hazard ratio. The study included 1213 patients with severe burn who underwent 2259 surgeries. Postoperative pulmonary complications were occurred in 313 (25.8%) patients. Among 2259 surgeries, sugammadex was used in 649 (28.7%) surgeries. Cumulative postoperative pulmonary complication were 268 (16.6%) cases in surgeries without sugammadex, and 45 (6.9%) cases in surgeries with sugammadex, respectively (P < 0.005). The postoperative pulmonary complications risk was reduced significantly in patients who use sugammadex than those who did not use sugammadex. (Adjusted hazard ratio, 0.61; 95% confidence interval, 0.42-0.89; P = 0.011). In conclusion, sugammadex reduced risk of postoperative pulmonary complications compared with nonuse of sugammadex in patients with severe burn who underwent surgery.

Abstract
Inhalation injury (II) is the third mortality prognostic factor for burn injury following age and burn size. II can lead to pulmonary complications such as pneumonia and acute respiratory distress syndrome (ARDS); all of which have been hypothesized to increase morbidity and mortality in II. Herein, we aimed to identify variables associated with the risk of developing pneumonia and to determine the impact of pneumonia on selected II outcomes. De-identified data from the Prospective Inhalation Study titled Inhalation Injury Scoring System to Predict Inhalation Injury Severity (ISIS) were used. II was confirmed by fiberoptic bronchoscopy. Demographics, injury, and hospital course information were recorded. P < .05 was considered significant. One hundred subjects were included. On univariate analysis, pneumonia was associated with burn severity, race, and receipt of colloid during the first 24 hours. Patients who developed pneumonia spent more time on a ventilator, had longer hospitalizations (LOS) and were more likely to need a tracheostomy. On multivariate analysis, total number of ventilator days was associated with pneumonia (Odd ratio (OR) = 1.122 [1.048-1.200], P = .001). Both pneumonia and receipt of colloid were predictive of increased ventilator days (OR = 2.545 [1.363-4.753], P < .001 and OR = 2.809 [1.548-5.098], P < .001, respectively). Pneumonia was not an independent predictor of LOS, ARDS, or mortality. Pneumonia remains a high-risk complication associated with two times more ventilator days in II. Future research should focus on prevention of pneumonia and the relationship between colloid fluids and pneumonia and early ventilator liberation in II patients.

Abstract
INTRODUCTION The Surviving Sepsis Campaign was developed to improve outcomes for all patients with sepsis. Despite sepsis being the primary cause of death after thermal injury, burns have always been excluded from the Surviving Sepsis efforts. To improve sepsis outcomes in burn patients, an international group of burn experts developed the Surviving Sepsis After Burn Campaign (SSABC) as a testable guideline to improve burn sepsis outcomes. METHODS The International Society for Burn Injuries (ISBI) reached out to regional or national burn organizations to recommend members to participate in the program. Two members of the ISBI developed specific "patient/population, intervention, comparison and outcome" (PICO) questions that paralleled the 2021 Surviving Sepsis Campaign [1]. SSABC participants were asked to search the current literature and rate its quality for each topic. At the Congress of the ISBI, in Guadalajara, Mexico, August 28, 2022, a majority of the participants met to create "statements" based on the literature. The "summary statements" were then sent to all members for comment with the hope of developing an 80% consensus. After four reviews, a consensus statement for each topic was created or "no consensus" was reported. RESULTS The committee developed sixty statements within fourteen topics that provide guidance for the early treatment of sepsis in burn patients. These statements should be used to improve the care of sepsis in burn patients. The statements should not be considered as "static" comments but should rather be used as guidelines for future testing of the best treatments for sepsis in burn patients. They should be updated on a regular basis. CONCLUSION Members of the burn community from the around the world have developed the Surviving Sepsis After Burn Campaign guidelines with the goal of improving the outcome of sepsis in burn patients.

Abstract
BACKGROUND The coronavirus disease pandemic has had a tangible impact on bronchoscopy for burn inpatients due to isolation and triage measures. We utilised the machine-learning approach to identify risk factors for predicting mild and severe inhalation injury and whether patients with burns experienced inhalation injury. We also examined the ability of two dichotomous models to predict clinical outcomes including mortality, pneumonia, and duration of hospitalisation. METHODS A retrospective 14-year single-centre dataset of 341 intubated patients with burns with suspected inhalation injury was established. The medical data on day one of admission and bronchoscopy-diagnosed inhalation injury grade were compiled using a gradient boosting-based machine-learning algorithm to create two prediction models: model 1, mild vs. severe inhalation injury; and model 2, no inhalation injury vs. inhalation injury. RESULTS The area under the curve (AUC) for model 1 was 0·883, indicating excellent discrimination. The AUC for model 2 was 0·862, indicating acceptable discrimination. In model 1, the incidence of pneumonia (P < 0·001) and mortality rate (P < 0·001), but not duration of hospitalisation (P = 0·1052), were significantly higher in patients with severe inhalation injury. In model 2, the incidence of pneumonia (P < 0·001), mortality (P < 0·001), and duration of hospitalisation (P = 0·021) were significantly higher in patients with inhalation injury. CONCLUSIONS We developed the first machine-learning tool for differentiating between mild and severe inhalation injury, and the absence/presence of inhalation injury in patients with burns, which is helpful when bronchoscopy is not available immediately. The dichotomous classification predicted by both models was associated with the clinical outcomes.

Abstract
BACKGROUND Burns is one of the most common traumas worldwide. Severely injured burn patients have an increased risk for mortality and morbidity. This study aimed to evaluate well-known risk factors for burn mortality and comparison of six machine learn-ing (ML) Algorithms' predictive performances. METHODS The medical records of patients who had burn injuries treated at Izmir Bozyaka Training and Research Hospital's Burn Treatment Center were examined retrospectively. Patients' demographics such as age and gender, total burned surface area (TBSA), Inhalation injury (II), full-thickness burns (FTBSA), and burn types (BT) were recorded and used as input features in ML models. Pa-tients were analyzed under two groups: Survivors and Non-Survivors. Six ML algorithms, including k-Nearest Neighbor, Decision Tree, Random Forest, Support Vector Machine, Multi-Layer Perceptron, and AdaBoost (AB), were used for predicting mortality. Several different input feature combinations were evaluated for each algorithm. RESULTS The number of eligible patients was 363. All six parameters (TBSA, Gender, FTBSA, II, Age, BT) that were included in ML algorithms showed a significant difference (p<0.001). The results show that AB algorithm using all input features had the best predic-tion performance with an accuracy of 90% and an area under the curve of 92%. CONCLUSION ML algorithms showed strong predictive performance in burn mortality. The development of an ML algorithm with the right input features could be useful in the clinical practice. Further investigations are needed on this topic.

Abstract
Acute respiratory distress syndrome (ARDS) is a leading cause of morbidity and mortality in polytrauma patients. Pharmacological treatments of ARDS are lacking, and ARDS patients rely on supportive care. Accurate diagnosis of ARDS is vital for early intervention and improved outcomes but is presently delayed up to days. The use of biomarkers for early identification of ARDS development is a potential solution. Inflammatory mediators high-mobility group box 1 (HMGB1), syndecan-1 (SDC-1), and C3a have been previously proposed as potential biomarkers. For this study, we analyzed these biomarkers in animals undergoing smoke inhalation and 40% total body surface area burns, followed by intensive care for 72 h post-injury (PI) to determine their association with ARDS and mortality. We found that the levels of inflammatory mediators in serum were affected, as well as the degree of HMGB1 and Toll-like receptor 4 (TLR4) signal activation in the lung. The results showed significantly increased HMGB1 expression levels in animals that developed ARDS compared with those that did not. Receiver operating characteristic (ROC) analysis showed that HMGB1 levels at 6 h PI were significantly associated with ARDS development (AUROC=0.77) and mortality (AUROC=0.82). Logistic regression analysis revealed that levels of HMGB1 ≥24.10 ng/ml are associated with a 13-fold higher incidence of ARDS [OR:13.57 (2.76-104.3)], whereas the levels of HMGB1 ≥31.39 ng/ml are associated with a 12-fold increase in mortality [OR: 12.00 (2.36-93.47)]. In addition, we found that mesenchymal stem cell (MSC) therapeutic treatment led to a significant decrease in systemic HMGB1 elevation but failed to block SDC-1 and C3a increases. Immunohistochemistry analyses showed that smoke inhalation and burn injury induced the expression of HMGB1 and TLR4 and stimulated co-localization of HMGB1 and TLR4 in the lung. Interestingly, MSC treatment reduced the presence of HMGB1, TLR4, and the HMGB1-TLR4 co-localization. These results show that serum HMGB1 is a prognostic biomarker for predicting the incidence of ARDS and mortality in swine with smoke inhalation and burn injury. Therapeutically blocking HMGB1 signal activation might be an effective approach for attenuating ARDS development in combat casualties or civilian patients.

Abstract
Burn care in the prehospital and emergency settings requires rapid assessment of airway, breathing, and circulation. Intubation (if indicated) and fluid resuscitation are most important in emergency burn care. Total body surface area burned and depth of burn are important early assessments that help guide resuscitation and disposition. Burn care in the emergency department further includes carbon monoxide and cyanide toxicity evaluation and management.

Abstract
The lung is extremely sensitive to interstitial fluid balance, yet the role of pulmonary lymphatics in lung fluid homeostasis and its interaction with cardiovascular pressures is poorly understood. In health, there is a fine balance between fluid extravasated from the pulmonary capillaries into the interstitium and the return of fluid to the circulation via the lymphatic vessels. This balance is maintained by an extremely interdependent system governed by pressures in the fluids (air and blood) and tissue (interstitium), lung motion during breathing, and the permeability of the tissues. Chronic elevation in left atrial pressure (LAP) due to left heart disease increases the capillary blood pressure. The consequent fluid accumulation in the delicate lung tissue increases its weight, decreases its compliance, and impairs gas exchange. This interdependent system is difficult, if not impossible, to study experimentally. Computational modeling provides a unique perspective to analyze fluid movement in the cardiopulmonary vasculature in health and disease. We have developed an initial in silico model of pulmonary lymphatic function using an anatomically structured model to represent ventilation and perfusion and underlying biophysical laws governing fluid transfer at the interstitium. This novel model was tested against increased LAP and noncardiogenic effects (increased permeability). The model returned physiologically reasonable values for all applications, predicting pulmonary edema when LAP reached 25 mmHg and with increased permeability.NEW & NOTEWORTHY This model presents a novel approach to understanding the interaction between cardiac dysfunction and pulmonary lymphatic function, using anatomically structured models and biophysical equations to estimate regional variation in fluid transport from blood to interstitial and lymphatic flux. This fluid transport model brings together advanced models of ventilation, perfusion, and lung mechanics to produce a detailed model of fluid transport in health and various altered pathological conditions.

Abstract
Alveolar epithelial cells (AECs) play a role in chemically induced acute lung injury (CALI). However, the mechanisms that induce alveolar epithelial type 2 cells (AEC2s) to proliferate, exit the cell cycle, and transdifferentiate into alveolar epithelial type 1 cells (AEC1s) are unclear. Here, we investigated the epithelial cell types and states in a phosgene-induced CALI rat model. Single-cell RNA-sequencing of bronchoalveolar lavage fluid (BALF) samples from phosgene-induced CALI rat models (Gas) and normal controls (NC) was performed. From the NC and Gas BALF samples, 37,245 and 29,853 high-quality cells were extracted, respectively. All cell types and states were identified and divided into 23 clusters; three cell types were identified: macrophages, epithelial cells, and macrophage proliferating cells. From NC and Gas samples, 1315 and 1756 epithelial cells were extracted, respectively, and divided into 11 clusters. The number of AEC1s decreased considerably following phosgene inhalation. A unique SOX9-positive AEC2 cell type that expanded considerably in the CALI state was identified. This progenitor cell type may develop into alveolar cells, indicating its stem cell differentiation potential. We present a single-cell genome-scale transcription map that can help uncover disease-associated cytologic signatures for understanding biological changes and regeneration of lung tissues during CALI.

Abstract
Fire smoke enters the human lungs through the respiratory tract. The damage to the respiratory tract and lung tissue is known as smoke inhalation injury (SII). Fire smoke can irritate airway epithelium cells, weaken endothelial cell adhesion and lyse alveolar type II epithelia cells, leading to emphysema, decreased lung function, pneumonia and risk of acute lung injury/acute respiratory distress syndrome (ARDS). The purpose of the present study was to analyze the clinical characteristics of patients with SII and the risk factors affecting their prognosis. A total of 103 patients with SII admitted between January 2016 to December 2021 to the Burns Unit of the Characteristic Medical Center of Chinese People's Armed Police Force and 983 Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army were selected for the present study. The demographics and clinical features between different severities of SII were analyzed. Univariate/multivariate logistic regression was used to analyze the potential predictors for severity, ARDS and mortality of patients with SII. Receiver operating characteristic (ROC) curves were used to screen independent risk factors and identify their prediction accuracy. It was concluded that total body surface area (TBSA), III burn area (of total %TBSA), cases of respiratory infections, ARDS morbidity, mortality, acute physiology and chronic health evaluation II, lung injury prediction score, lactic acid, white blood cells (WBC), alanine transaminase, blood urea nitrogen, serum creatinine and uric acid were indicators that were raised with increasing severity of SII. However red blood cells, hemoglobin, platelet count, total protein, albumin, and albumin/globulin were decreased with the increasing severity of SII (P<0.05). WBC >20.91 (109/l) was a reliable indicator for severe SII. Lactic acid >9.60 (mmol/l) demonstrated a high degree of accuracy in predicting ARDS development in patients with SII. Hemoglobin <83.00 (g/l) showed a high degree of accuracy in predicting mortality. In summary, the highlighted assessment parameters could be used to contribute to devising improved treatment plans to preempt worsening conditions (such as shock, ARDS, multiple organ dysfunction syndrome and death).

Abstract
Acute respiratory distress syndrome (ARDS) is a life-threatening lung injury characterized by an acute inflammatory response in the lung parenchyma. Hence, it is considered as the most appropriate clinical syndrome to study pathogenic mechanisms of lung inflammation. ARDS is associated with increased morbidity and mortality in the intensive care unit (ICU), while no effective pharmacological treatment exists. It is very important therefore to fully characterize the underlying pathobiology and the related mechanisms, in order to develop novel therapeutic approaches. In vivo and in vitro models are important pre-clinical tools in biological and medical research in the mechanistic and pathological understanding of the majority of diseases. In this review, we will present data from selected experimental models of lung injury/acute lung inflammation, which have been based on clinical disorders that can lead to the development of ARDS and related inflammatory lung processes in humans, including ventilation-induced lung injury (VILI), sepsis, ischemia/reperfusion, smoke, acid aspiration, radiation, transfusion-related acute lung injury (TRALI), influenza, Streptococcus (S.) pneumoniae and coronaviruses infection. Data from the corresponding clinical conditions will also be presented. The mechanisms related to lung inflammation that will be covered are oxidative stress, neutrophil extracellular traps, mitogen-activated protein kinase (MAPK) pathways, surfactant, and water and ion channels. Finally, we will present a brief overview of emerging techniques in the field of omics research that have been applied to ARDS research, encompassing genomics, transcriptomics, proteomics, and metabolomics, which may recognize factors to help stratify ICU patients at risk, predict their prognosis, and possibly, serve as more specific therapeutic targets.

Abstract
Care of the critically injured burn patient presents unique challenges to the intensivist. Certified burn centers are rare and geographically sparse, necessitating that much of the initial management of patients with severe burn injuries must happen in the pre-burn center setting.1 Severe burn injuries often lead to a wide range of complications that extend beyond the loss of skin integrity and require specialized care. As such, medical intensivists are often called upon to stabilize these critically injured patients. This focused review outlines the clinical care of these medically complex patients, including airway management, post-burn complications, volume resuscitation, nutrition, and end-of-life care.

Abstract
Abstract
Scald is one type of burn that s often mentioned alone and occurs mostly in the paediatric population. Inhaled steam is mostly cooled off in the airways, why thermal damage is rarely seen. A sudden exposure to hot steam/inhalation can cause a thermal inhalation injury. A scoping review was performed, with the aim to summarize all published papers in English, about steam-related injuries. The search was conducted using the PubMed® and Cochrane libraries on 19th of May 2021, without a set time period. Out of a total of 1186 identified records, 31 were chosen for review. Burns related to the contact with steam are generally rare and can be both minor and severe. The more severe cases related to steam exposure are mostly workplace accidents and the minor injuries reported in the literature are often related to steam inhalation therapy, especially in the paediatric population. This review describes the challenges that can be found dealing with patients suffering from cutaneous steam burns and/or steam inhalation injuries. A steam injury to the airways or the skin can be directly life-threatening and should be treated with caution. This type of injury can lead to acute respiratory insufficiency and sometimes death. A case of a male patient with extensive cutaneous steam burns and a steam inhalation injury who passed away after 11 days of treatment is also presented to illustrate this review.

Abstract
Lung injury from smoke inhalation manifests as airway and parenchymal damage, at times leading to the acute respiratory distress syndrome. From the beginning of this millennium, the approach to mechanical ventilation in the patient with ARDS was based on reduction of tidal volume to 6 milliliters/kilogram of ideal body weight, maintaining a ceiling of plateau pressure, and titration of driving pressure (plateau pressure minus PEEP). Beyond these broad constraints, there is little specification for the mechanics of ventilator settings, consideration of the metabolic impact of the disease process on the patient, or interaction of patient disease and ventilator settings. Various studies suggest that inhomogeneity of lung injury, which increases the risk of regional lung trauma from mechanical ventilation, may be found in the patient with smoke inhalation. We now appreciate that energy transfer principles may affect optimal ventilator management and come into play in damaged heterogenous lungs. Mechanical ventilation in the patient with inhalation injury should consider various factors. Self-injurious respiratory demand by the patient can be reduced using analgesia and sedation. Dynamic factors beginning with rate management can reduce the incidence of potentially damaging ventilation. Moreover, preclinical study is underway to examine the flow of gas based on the ventilator mode selected, which may also be a factor triggering regional lung injury.

Abstract
A retrospective study was conducted on 314 burn patients with inhalation injury admitted to the National Burn Hospital during the period 2015-2019. The results showed that adult and male was predominant (81.9% and 77.7%), with burns mostly caused by flame (93.6%) and burn extent of 68.6±24.3% and deep burn area of 44.6±25.2% total body surface area. Rate of required mechanical ventilation patients was 95.22%. Common complications were multiple organ failure (41.9%), pneumonia (29.9%), ARDS (25.5%) and septic shock (23.8%), with a mortality rate of 85.4%. Multivariate logistic analysis indicated that burn extent and age were independent risk factors for death of patients with inhalation injury. SMR of rBaux score was 1.01 with AUC of 0.84, Youden index 113, sensitivity 82.09%, specificity 70.21%. The SMR of adult and elderly patients was relatively close to 1 (1 and .97 respectively). In addition, the AUC value for the elderly was highest (.95) followed by adult patients (.84). However, predicting the value of rBaux on children with inhalation injury was quite low (SMR=1.57; AUC = 0.4). There is a need to determine an optimal prognosis score for children with inhalation injury.

Positive signs on physical examination are not always indications for endotracheal tube intubation in patients with facial burn. BMC Emerg Med 2022; 22:36. [PMID: 35260094 PMCID: PMC8903723 DOI: 10.1186/s12873-022-00594-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 02/24/2022] [Indexed: 11/10/2022] Open
Abstract
Background After clinical evaluation in the emergency department (ED), facial burn patients are usually intubated to protect their airways. However, the possibility of unnecessary intubation or delayed intubation after admission exists. Objective criteria for the evaluation of inhalation injury and the need for airway protection in facial burn patients are needed. Methods Facial burn patients between January 2013 and May 2016 were reviewed. Patients who were and were not intubated in the ED were compared. All the intubated patients received routine bronchoscopy and laboratory tests to evaluate whether they had inhalation injuries. The patients with and without confirmed inhalation injuries were compared. Multivariate logistic regression analysis was used to identify the independent risk factors for inhalation injuries in the facial burn patients. The reasons for intubation in the patients without inhalation injuries were also investigated. Results During the study period, 121 patients were intubated in the ED among a total of 335 facial burn patients. Only 73 (60.3%) patients were later confirmed to have inhalation injuries on bronchoscopy. The comparison between the patients with and without inhalation injuries showed that shortness of breath (odds ratio = 3.376, p = 0.027) and high total body surface area (TBSA) (odds ratio = 1.038, p = 0.001) were independent risk factors for inhalation injury. Other physical signs (e.g., hoarseness, burned nostril hair, etc.), laboratory examinations and chest X-ray findings were not predictive of inhalation injury in facial burn patients. All the patients with a TBSA over 60% were intubated in the ED even if they did not have inhalation injuries. Conclusions In the management of facial burn patients, positive signs on conventional physical examinations may not always be predictive of inhalation injury and the need for endotracheal tube intubation in the ED. More attention should be given to facial burn patients with shortness of breath and a high TBSA. Airway protection is needed in facial burn patients without inhalation injuries because of their associated injuries and treatments.

Abstract
Burn injuries contribute significantly to childhood morbidity and mortality. This study was designed to document the pattern of presentation and outcome of pediatric burn injury in Enugu. METHODS All children with burn injuries over a 7-year period (June 2011 to May 2018) and were managed at three tertiary health institutions, were studied. Information including their socio-demographics, clinical features and treatment outcome were obtained and analyzed using the Statistical Package for Social Sciences (SPSS) version 17.0. RESULTS 198 out of 201 records were available for analysis. Most (186; 93.9%) burn injuries occurred at home. Hot liquid (112; 56.7%) was the commonest cause of burn injury. A lot of substances were used topically for first aid, raw eggs (52; 31%) being the commonest. The outcome had significant association with cause of injury, depth of injury, total burn surface area (TBSA), and inhalation injury. Most were safely discharged home while a total of thirteen (6.6%) children died. LA50 was 54.87%, while the maximum TBSA salvaged was 65%. CONCLUSION Burn injuries in children in this environment remain a serious challenge in the face of widespread lack of awareness regarding safe practices in handling hot and flammable items at home.

Abstract
Early mobilization with mechanically ventilated patients has received significant attention within recent literature, however limited research has focused specifically on the burn population. The purpose of this single center, retrospective analysis was to review the use of a burn critical care mobility algorithm, to determine safety and feasibility of a burn vented mobility program, share limitations preventing mobility progression at our facility, and discuss unique challenges to vented mobility with intubated burn patients. A retrospective review was completed for all intubated burn center admissions between January 2015 to December 2019. Burn Therapy notes were then reviewed for data collection, during the intubation period, using stages of the mobility algorithm. In 5 years following initial implementation, the vented mobility algorithm was utilized on 127 patients with an average total body surface area of 22.8%. No adverse events occurred. Stage 1 (Range of motion) was completed with 100% of patients (n=127). Chair mode of bed, stage 2a, was utilized in 39.4%(n=50) of patients, while 15.8% (n=20) of patients were dependently transferred to the cardiac chair in stage 2b. Stage 3 (sitting on the edge-of-bed) was completed with 25% (n=32) of patients, with 11% (n=14) progressing to stage 5 (standing), and 3.9% (n=5) actively transferring to a chair. In 5 years, only 4.7% (n=6) reached stage 6 (ambulation). The most common treatment limitations were medical complications (33%) and line placement (21%). Early mobilization during mechanical ventilation is safe and feasible within the burn population, despite challenges including airway stability, sedation, and line limitations.

Abstract
Numerous burn mortality indicators and prognostic scores are necessary to classify with priorities severely burned patients in order to predict outcome. The purpose of this paper is to evaluate mortality predictors on admission, in order to determine Lethal Area 50 and to validate burn prognostic scores. The study is retrospective, clinical and analytical. The data utilized were accessed by investigating the medical charts of 5033 patients hospitalized with severe burns within the Intensive Care Unit of the Service of Burns in Tirana, Albania over the period 1992-2019. Descriptive and inferential statistics were performed using PSS 23 software. Statistical significance is defined as p<0.05. The incidence rate of hospitalization of patients with severe burns initially increased from 4.1 to 7.9 persons per 100,000 population/year in the period 1992 to 1999, followed by a decrease from 7.9 to 4.8 in 2019. Mortality was 12.2% and the average burn crude death rate was 0.7 patients per 100,000 population/year. Lethal Area 50 for the second decade (2010-2019) was 82.2%. All tested burn prognostic scores had good predictive values. In addition to the commonly used outcome predictors such as age, burn size and inhalation burn, we concluded that additional determinants like depth of burn and etiology of burns determined an unfavorable outcome. Fatality risk was 4 times higher in patients with full-thickness burns, 2.6 times higher in patients with flame burns, and 4 times higher in patients with inhalation injury.

Abstract
INTRODUCTION Burns inhalation injury increases the attributable mortality of burns related trauma. However, diagnostic uncertainties around bronchoscopically graded severity, and its effect on outcomes, remain. This study evaluated the impact of different bronchoscopic burns inhalation injury grades on outcomes. METHODS A single-centre cohort study of all patients admitted to the London Burns centre intensive care unit (BICU) over 12 years. Demographic data, burn and burns inhalation injury characteristics, and ICU-related parameters were collected retrospectively. The primary outcome was mortality. Secondary outcomes were hospital and ICU lengths of stay. The impact of pneumonia was determined. Univariate and multivariable Cox's proportional hazards regression analyses informed factors predicting mortality. RESULTS Burns inhalation injury was diagnosed in 84 of 231 (36%) critically ill burns patients; 20 mild (grade 1), 41 severe (grades 2/3) and 23 unclassified bronchoscopically. Median (IQR) total body surface area burned (TBSA) was 20% (10-40). Mortality was significantly higher in patients with burns inhalation injury vs those without burns inhalation injury (38/84 [45%] vs 35/147 [24%], p < 0.001). Patients with pneumonia had a higher mortality than those without (34/125 [27%] vs 8/71 [11%], p = 0.009). In multivariable analysis, severe burns inhalation injury significantly increased mortality (adjusted HR=2.14, 95%CI: 1.12-4.09, p = 0.022), compared with mild injury (adjusted HR=0.58, 95% CI: 0.18-1.86, p = 0.363). Facial burns (adjusted HR=3.13, 95%CI: 1.69-5.79, p < 0.001), higher TBSA (adjusted HR=1.05, 95%CI: 1.04-1.06, p < 0.001) and older age (adjusted HR=1.04, 95%CI: 1.02-1.07, p < 0.001) also independently predicted mortality, though pneumonia did not. CONCLUSIONS Severe burns inhalation injury is a significant risk factor for mortality in critically ill burns patients. However, pneumonia did not increase mortality from burns inhalation injury. This work confirms prior implications of bronchoscopically graded burns inhalation injury. Further study is suggested, through registries, into the diagnostic accuracy and reliability of bronchoscopy in burns related lung injury.

Abstract
This research reveals that drugs and chemicals poisoning have been reported to have severe and fetal side effects on health provided by doctors in statistics and periodical records. This work aimed to explore the interaction among drug and chemical poisoning patterns concerning risk factors, especially gender, age, exposure circumstances, and outcomes in the Makkah region. A retrospective analysis was of clinical drug and chemical poisoning cases (2014-2015). The data were retrieved from the Department of Environmental and Occupational Health, Ministry of Health, Makkah, Saudi Arabia. The Saudi Arabia Ministry of Health received 1216 reports of drug and chemical poisoning during 2014-2015 in Makkah. This study has found that, the most affected gender was that of males (65%). The most affected age category with drug poisoning was over 15 years old (67%), but under 5 years for chemical poisoning (60%). The majority of drug poisoning cases are unknown drugs (42%), which accidental poisoning was a minority compared with other drug causes (27%). Chemical poisoning accidents were the majority causes of the recorded cases (63%). We reported healthy recovered without complications for most patients from drug and chemical poisoning (85-95%). Antidotes were administered in only (5%) of cases, and fatalities were reported (0.5% of cases). We have shown a flagrant increase in the number of people poisoned by drugs and chemical agents during 2015. Increases poisoning cases involved both genders and all studied age categories, especially males over 15 years up to 25 (drugs) and < 5 years (chemicals). Most cases were accidental (chemicals) and reported healthy recovery for most patients.

[PMID: 34740320 PMCID: PMC8569503 DOI: 10.1186/s12871-021-01488-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 10/26/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND An airway-associated fire in an operating room can have devastating consequences for patients. Breathing circuit warmers (BCWs) are widely used to provide heated and humidified anesthetic gases and eventually prevent hypothermia during general anesthesia. Herein, we describe a case of a BCW-related airway fire. CASE PRESENTATION In this case, an electrical short within a BCW wire caused a fire inside the circuit. Simultaneously, the fire was extinguished, ventilation was stopped, and the endotracheal tube was disconnected from the BCW. The patient was exposed to the fire for less than 10 s, resulting in burns to the trachea and bronchi. Immediately after airway burn, bronchoscopy showed no edema or narrowing except for soot in the trachea and both main bronchus. After the inhalation burn event, prophylactic antibiotics, bronchodilator, mucolytics nebulizer, and corticosteroid nebulizer were started. On bronchoscopy 3 days after the inhalation burn, mucosal erythematous edema was observed and the inflammatory reaction worsened. The inflammatory reaction showed aggravation for up to 2 weeks, and then gradually recovered, and the epithelium and mucous membrane of the upper respiratory tract returned to normal after 4 weeks. Eventually, the patient recovered without long-term complications and was successfully discharged. CONCLUSIONS This is the first report of a fire caused by BCW. We wanted to share our experience of how we responded to an airway-related fire in an OR and treated the patient. It cannot be overemphasized that the electrical medical appliance associated with the airways are fatal to the patient in the event of a fire, so caution should always be exercised.

Abstract
BACKGROUND Although it has been widely proposed that inhalation injuries worsen burn outcomes, large-scale studies have yet to demonstrate the exact relationship. This study proposes inhalation injuries as an independent risk factor that worsens burn outcomes. METHODS A retrospective review of the American Burn Association Registry from 2002 to 2011 was conducted. Inclusion criteria included burn patients with a total body surface area (TBSA) of less than 15% and adequate data recording of the inhalation injury within the registry. Patients were stratified into 2 groups: inhalation injuries (group 1) vs non-inhalation injuries (group 2). Outcome measures included in-hospital mortality rate, hospital length of stay (LOS), intensive care unit (ICU) LOS, and days on a ventilator. RESULTS A total of 93781 burn patients met the inclusion criteria. There were 4204 patients in group 1 and 89577 patients in group 2. There was no statistically significant difference between the 2 groups in terms of TBSA, with 3.50% in group 1 and 3.58% in group 2. There was a significantly higher ICU LOS at 8.55 days in group 1 compared to 6.27 days in group 2. There was a significantly higher hospital LOS at 11.48 days in group 1 compared to 6.27 days in group 2. The in-hospital mortality was significantly higher in group 1 at 8.54% vs group 2 at 1.42%. CONCLUSION The presence of inhalation injury may be a predictor of increased mortality and poor outcome in burn patients, even in those with small sized burns.

Veno-venous extracorporeal blood phototherapy increases the rate of carbon monoxide (CO) elimination in CO-poisoned pigs. Lasers Surg Med 2021; 54:256-267.

Abstract
BACKGROUND AND OBJECTIVES Carbon monoxide (CO) inhalation is the leading cause of poison-related deaths in the United States. CO binds to hemoglobin (Hb), displaces oxygen, and reduces oxygen delivery to tissues. The optimal treatment for CO poisoning in patients with normal lung function is the administration of hyperbaric oxygen (HBO). However, hyperbaric chambers are only available in medical centers with specialized equipment, resulting in delayed therapy. Visible light dissociates CO from Hb with minimal effect on oxygen binding. In a previous study, we combined a membrane oxygenator with phototherapy at 623 nm to produce a "mini" photo-ECMO (extracorporeal membrane oxygenation) device, which improved CO elimination and survival in CO-poisoned rats. The objective of this study was to develop a larger photo-ECMO device ("maxi" photo-ECMO) and to test its ability to remove CO from a porcine model of CO poisoning. STUDY DESIGN/MATERIALS AND METHODS The "maxi" photo-ECMO device and the photo-ECMO system (six maxi photo-ECMO devices assembled in parallel), were tested in an in vitro circuit of CO poisoning. To assess the ability of the photo-ECMO device and the photo-ECMO system to remove CO from CO-poisoned blood in vitro, the half-life of COHb (COHb-t1/2 ), as well as the percent COHb reduction in a single blood pass through the device, were assessed. In the in vivo studies, we assessed the COHb-t1/2 in a CO-poisoned pig under three conditions: (1) While the pig breathed 100% oxygen through the endotracheal tube; (2) while the pig was connected to the photo-ECMO system with no light exposure; and (3) while the pig was connected to the photo-ECMO system, which was exposed to red light. RESULTS The photo-ECMO device was able to fully oxygenate the blood after a single pass through the device. Compared to ventilation with 100% oxygen alone, illumination with red light together with 100% oxygen was twice as efficient in removing CO from blood. Changes in gas flow rates did not alter CO elimination in one pass through the device. Increases in irradiance up to 214 mW/cm2 were associated with an increased rate of CO elimination. The photo-ECMO device was effective over a range of blood flow rates and with higher blood flow rates, more CO was eliminated. A photo-ECMO system composed of six photo-ECMO devices removed CO faster from CO-poisoned blood than a single photo-ECMO device. In a CO-poisoned pig, the photo-ECMO system increased the rate of CO elimination without significantly increasing the animal's body temperature or causing hemodynamic instability. CONCLUSION In this study, we developed a photo-ECMO system and demonstrated its ability to remove CO from CO-poisoned 45-kg pigs. Technical modifications of the photo-ECMO system, including the development of a compact, portable device, will permit treatment of patients with CO poisoning at the scene of their poisoning, during transit to a local emergency room, and in hospitals that lack HBO facilities.

Abstract
Quantitative methods for assessing the severity of inhalation (burn) injury are needed to aid in treatment decisions. We hypothesize that it is possible to assess the severity of injuries on the basis of differences in the compliance of the airway wall. Here, we demonstrate the use of a custom-built, endoscopic, anatomic optical coherence elastography (aOCE) system to measure airway wall compliance. The method was first validated using airway phantoms, then performed on ex vivo porcine tracheas under varying degrees of inhalation (steam) injury. A negative correlation between aOCE-derived compliance and severity of steam injuries is found, and spatially-resolved compliance maps reveal regional heterogeneity in airway properties.

Abstract
Objective To evaluate serum uteroglobin-related protein 1 expression early after smoke inhalation injuries and its association with the severity of inhalation injury in burned patients. Methods Smoke or chemical inhalation injury is associated with morbidity and mortality. The consequences of inhalation result from an inflammatory response. Uteroglobin-related protein 1 is an anti-inflammatory protein and may improve lung inflammation. We hypothesized that uteroglobin-related protein 1 levels could reflect disease severity and predict outcome in patients with inhalation injury. Sixteen patients diagnosed with acute respiratory distress syndrome secondary to smoke inhalation injury were prospectively included in the study. Plasma was collected upon intensive care unit admission and within 24 hours of the inhalation injury. Bronchoscopies were carried out in all patients to assess the severity of inhalation injury within 72 hours. Uteroglobin-related protein 1 plasma levels were determined in duplicate with enzyme-linked immunosorbent assay. Results The mean age was 23 ± 5 years, and the inhalation injury distribution was as follows: three of grade 1, four of grade 2, and nine of grade 3. The level of uteroglobin-related protein 1 was related to inhalation severity (grade 1: 0.389 ± 0.053 arbitrary units versus grade 2: 0.474 ± 0.0423 arbitrary units versus grade 3: 0.580 ± 0.094 arbitrary units; p = 0.007). Conclusion Plasma levels of uteroglobin-related protein 1 are associated with the degree of lung inhalation injury.

Abstract
Inhalational lung injury often leads to morbidity and mortality during fire disasters. In this study, we aimed to evaluate the protective effects of edaravone combined with dexamethasone on smoke-induced inhalational lung injury. Sprague-Dawley rats were divided into five groups, namely, the control, model (inhalation), and three treatment groups (edaravone, dexamethasone, and edaravone combined with dexamethasone). After drug intervention in the acute lung injury model, arterial blood gas, wet:dry weight ratio of the lung tissue, bronchoalveolar lavage fluid, and pulmonary histopathology were determined. The production of reactive oxygen species (ROS), mitochondrial membrane potential (MMP), inflammatory cytokines, peroxidase and apoptosis were further analyzed to explore the underlying mechanisms. The results of blood gas and inflammatory cytokine analysis and the histopathological data demonstrated that edaravone combined with dexamethasone had obvious protective effects on smoke infiltration and tissue injury. Moreover, after the co-administration of edaravone and dexamethasone, malondialdehyde and myeloperoxidase levels in the lung tissue decreased, whereas those of glutathione peroxidase and superoxide dismutase were elevated. In addition, this drug combination could inhibit smoke-induced apoptosis in lung tissues by reducing the cleavage of caspase-3, caspase-9, and poly ADP-ribose polymerase (PARP), and also reverse smoke-mediated mitochondrial dysfunction, including ROS generation, loss of MMP, early release of cytochrome C, second mitochondrial activator of caspases, and apoptosis-inducing factor. In conclusion, edaravone combined with dexamethasone had a protective effect on smoke-induced inhalational lung injury in rats and can be further explored as an attractive therapeutic option for the treatment of smoke inhalation-induced pulmonary dysfunction.

Abstract
Serious burn injuries may have lifelong impacts for individuals that experience them and require timely medical treatment in order to reduce associated morbidity and mortality. Initial management of a burn is nursing intensive and focuses primarily on stopping the burning process, maintaining homeostasis by keeping the patient warm, and replacing lost fluid and electrolytes. As healing progresses, nurses meet the critical needs of the patient and must skillfully manage pain levels, perform burn care, prevent infection, help the patient meet increased nutrient requirements, and address psychological concerns with the goal to restore health and function to the highest possible level.

Abstract
OBJECTIVES To evaluate the dose effects of Recombinant human Club cell 10-kDa protein (rhCC10) on lung function in a well-characterized ovine model of acute respiratory distress syndrome (ARDS) induced by smoke inhalation injury (SII); specifically, the potential of rhCC10 protein to control the inflammatory response and protect pulmonary tissue and function following SII. DESIGN Randomized, controlled, prospective, and large animal translational studies. SETTING University large animal intensive care unit. SUBJECTS Thirty-six adult female sheep were surgically prepared and allocated into five groups (Sham (no SII), n = 6; 1 mg/kg/d CC10, n = 8; 3 mg/kg/d CC10, n = 7; 10 mg/kg/d CC10, n = 8; Control SII, n = 7). INTERVENTIONS All groups except the sham group were subjected to SII with cooled cotton smoke. Then, the animals were placed on a ventilator, treated with 1, 3, and 10 mg/kg/d of intravenous rhCC10 or vehicle, divided evenly into two administrations per day every 12 h, fluid resuscitated, and monitored for 48 h in a conscious state. MEASUREMENTS AND MAIN RESULTS The group treated with 10 mg/kg/d rhCC10 attenuated changes in the following variables: PaO2/FiO2 ratio, oxygenation index, and peak inspiratory pressure; neutrophil content in the airway and myeloperoxidase levels; obstruction of the large and small airways; systemic leakage of fluid and proteins, and pulmonary edema. CONCLUSIONS In this study, high-dose rhCC10 significantly attenuated ARDS progression and lung dysfunction and significantly reduced systemic extravasation of fluid and proteins, normalizing fluid balance. Based on these results, rhCC10 may be considered a novel therapeutic option for the treatment of SII-induced ARDS.

Abstract
Smoke inhalation results in bronchospasm of the trachea, increasing secretion of mucus, casts formation, and improvement of blood flow of the airway. High frequency chest wall oscillation is a common modality used for clearing mucus secretion in patients suffering from hypersecretion of thick mucus and used also to help cough clearance. This study aimed to detect the effect of high frequency chest wall oscillation in improving pulmonary function in burn patients suffering from smoke inhalation. Sixty smoke inhalation injury patients were randomly distributed into two groups of equal size. Group A: received high frequency chest wall oscillation and conventional chest physical therapy (breathing exercises, early ambulation, and cough training) thrice per week for 8 weeks. Group B: received traditional chest physical therapy (breathing exercises, early ambulation, and cough training) thrice per week for 8 weeks. Pulmonary function test (forced vital capacity, forced expiratory volume in the first second and peak expiratory flow rate) was measured at enrollment and after 8 weeks by using spirometer. Pulmonary function increased significantly posttreatment when compared with that pretreatment in groups A and B (P > .001). Also, they increased significantly in group A compared with that of group B posttreatment (P > .05). High-frequency chest wall oscillation have an impact on improving pulmonary function and should be handled to be a part of the pulmonary rehabilitation plan for smoke inhalation injury patients.

Abstract
Laryngeal inhalation injury carries a significant increase in mortality rate and often indicates immediate airway evaluation. This may be difficult in the setting of clinical deterioration necessitating immediate intubation, which itself can synergistically cause mucosal damage. Prior studies do not encompass predictive factors or long-term outcomes for the laryngotracheal complex. This systemic review of PubMed, Embase, and Cochrane identified studies investigating inhalational injuries of the upper airway. Demographic data as well as presentation, physical findings, and delayed sequelae were documented. Laryngotracheal burn patients were divided into two cohorts based on timing of laryngeal injury diagnosis (before- versus after-airway intervention). 1051 papers met initial search criteria and 43 studies were ultimately included. Airway stenosis was more common in patients that were intubated immediately (50.0%, n = 18 versus 5.2%, n = 13; p = 0.57). Posterior glottic involvement was only identified in patients intubated prior to airway evaluation (71.4%, n = 15). All studies reported a closed space setting for those patients in whom airway intervention preceded laryngeal evaluation. Laryngeal inhalational injuries are a distinct subset that can have a variety of minor to severe laryngotracheal delayed sequelae, particularly for thermal injuries occurring within enclosed spaces. Given these findings, early otolaryngology referral may mitigate or treat these effects.

JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2021; 55:95-101. [PMID: 33563562 DOI: 10.1016/j.jmii.2021.01.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 01/18/2021] [Accepted: 01/18/2021] [Indexed: 01/25/2023]
Abstract
BACKGROUD/PURPOSE Bloodstream infections (BSI) are common in patients with major burns, but its effect on mortality remains controversial. This study was aimed to investigate if BSI is significant risk factor of mortality? METHODS This is a retrospective chart review study included 266 adult patients admitted to our burn center from 2000 to 2019. Age, sex, inhalation injuries, total burn surface area (TBSA), duration of stay in intensive care unit, BSI and mortality were variables studied. Fisher exact test, Mann-Whitney test and logistic regression was used for statistical analysis. RESULTS There were 234 survivors and 32 non-survivors. Male was predominant. The overall incidence of BSI was 18.8%, and the overall crude mortality was 12%. Burns ≥30% TBSA and BSI were significant risk factors. A predictive function based on30% TBSA and BSI within 14 days after the onset of burns (BSI-14) was derived. The function has a sensitivity of 0.97, specificity of 0.42 and achieved a maximum Youden Index at functional value ≥0.05727. The mortality probability of BSI-14 in burns ≥30% TBSA was 40.8%. CONCLUSIONS BSI and burns ≥30% TBSA were significant risk factors of mortality. Early detection of BSI-14 is critical in burn care as its probability of mortality can be as high as 40% in patients ≥30% TBSA of burns. To reduce the risk of mortality, early in ventilator withdrawal, invasive lines and tubes removal, and early grafting should be emphasized besides infection control and appropriate use of antibiotics.

Abstract
PURPOSE To examine the associations between premorbid nutritional status and in-hospital mortality in severe burn patients according to age in Japan. METHODS We retrospectively extracted the data of 14,345 patients aged 18-84 years admitted for burns from April 1, 2014, to March 31, 2018, using the Japanese Diagnosis Procedure Combination database. The exclusion criteria were out-of-hospital cardiac arrest, death in the emergency room, readmission, and planned admission. We collected data on age, sex, height, weight, comorbidities, burn index, and mechanical ventilation use and performed age-stratified multilevel logistic regression analyses to estimate associations between premorbid body mass index (BMI) and in-hospital mortality. RESULTS We analyzed 2968 patients with a burn index ≥10, including 831 elderly aged 75-84 years. In patients aged 18-74 years, being underweight (BMI < 18.5) significantly decreased mortality (0.34 [0.15-0.77]; P = 0.010). In contrast, in patients aged 75-84 years, being underweight significantly increased mortality (2.11 [1.05-4.25]; P = 0.036). Being overweight (BMI >25) increased mortality in both age groups, but not significantly. CONCLUSIONS The results suggest that pre-morbidly underweight elderly patients aged 75-84 years with severe burns have high mortality risks. Further research is needed to identify optimal care strategies for this population.
