Abstract
A minor insult to the pediatric airway can have a devastating result. Unfortunately, the signs and symptoms of obstruction might not be present immediately and take some time to develop. Therefore, physicians should have a higher index of suspicion for airway obstruction in children that present with a history of ingestion of scalding liquid. Signs and symptoms of infectious vs noninfectious epiglottis do overlap and the key to differentiate is by careful history and physical exam, especially in nonverbal children. A secondary bacterial infection might complicate thermal epiglottis and make the picture a bit confusing. Therefore, a coordinated approach through a multidisciplinary team is indicated from the start and these cases should be managed and referred to a higher center.

Abstract
INTRODUCTION Previous analyses of tracheostomy in paediatric burns was hindered by a lack of multi-institution or nationwide analysis. This study aims to explore the effects of tracheostomy in paediatric burn patients in such an analysis. De-identified data was obtained from the TriNetX Research Network database. METHODS Two cohorts were identified using ICD and CPT codes: paediatric burn patients with tracheostomy (cohort 1) and paediatric burn patients without tracheostomy (cohort 2). Cohorts were matched according to age at diagnosis and pulmonary condition, specifically influenza and pneumonia, respiratory failure, acute upper respiratory infection, and pulmonary collapse. Cohorts were also matched for age at burn diagnosis and surface area burned. Several parameters including infection following a procedure, sepsis, volume depletion, respiratory disorders, laryngeal disorders, pneumonia, and other metrics were also compared. RESULTS A total of 152 patients were matched according to age and pulmonary condition. Cohort 1 and cohort 2 had a mean age of 4.45 ± 4.06 and 4.39 ± 3.99 years, respectively. Matched patients with tracheostomy had a higher risk for pneumonia, respiratory failure, other respiratory disorders, diseases of the vocal cord and larynx, sepsis, volume depletion, pulmonary edema, and respiratory arrest. The risk ratios for these outcomes were 2.96, 3.5, 3.13, 3.9, 2.5, 2.5, 3.3, and not applicable. Analysis of longitudinal outcomes of paediatric burn patients with tracheostomy vs. those without demonstrated the tracheostomy cohort suffered much worse morbidity and experienced higher health burden across several metrics. CONCLUSION The potential benefits of tracheostomy in paediatric burn patients should be weighed against these outcomes.

Abstract
Burns on the face pose unique management challenges because they are in a place that is constantly visible, so scars are hard to hide. The goal of this study was to review our experience of adult patients who had face burns. We performed a retrospective review of adult patients (≥18 years old) who were admitted to a regional burn center from July 2015 to June 2019 with face burns. Sex, age, ethnicity, burn etiology, burn size, and discharge status were collected from electronic medical records of the patients who met study criteria. Descriptive statistics, Student's t-tests, and chi-square tests were performed in Stata/SE 16.1. Significance was defined as a P-value < .05. In 4 years, 595/1705 patients (~35% of admissions) were admitted with face burns. The mean age was 44.9 ± 17.0 (mean ± SD) years, with the majority being men (475, 80%). The mean burn size was 19.8 ± 20.9% TBSA with 10.1 ± 19.8% TBSA being third degree. The mean head burn size for any face burn was 2.8 ± 1.8% TBSA. The majority of burns were due to flames (478, 80%) and of those 122 (21%) were from accelerant use and 43 (7%) resulted from propane or butane use. Scalds caused 53 (9%), electric 25 (4%), hot tar 5 (1%), and chemical 5 (1%). Overall, 208 (35%) patients had grafting of some portion of their body, but only 31 patients (5.2%) had face grafting. The mean age of those with face grafting compared with patients who did not need grafting was 45.9 ± 13.8 and 44.9 ± 17.2 years, respectively. Patients who needed grafting had a mean third-degree burn size of 31.7 ± 25.4% TBSA and a mean head (including face) burn size of 4.7 ± 2.0% TBSA, whereas patients who did not need grafting had a mean third-degree burn size of 8.9 ± 18.7% TBSA and a mean head burn size of 2.7 ± 1.8% head TBSA. Patients requiring face grafts had longer lengths of stay, intensive unit stays, ventilator days, and mortality than those whose face burns healed spontaneously. Overall, head burns in adults were common within the 4-year time span we studied, but only a small fraction (5%) had face grafts. The patients who needed grafting for their head burns had significantly larger total body and face burns and had a 2.4-fold higher mortality rate compared to patients who did not need grafting. Most face burns were caused by flame, especially the use of accelerants or flammable gases. Prevention efforts should focus on avoiding the use of accelerants and being careful with flammable gases.

Abstract
OBJECTIVES To evaluate the optimal timing of tracheostomy for injured adolescents. DESIGN Retrospective cohort study. SETTING Trauma facilities in the United States. PATIENTS Adolescents (age 12-17 yr) in the National Trauma Data Bank (2007-2016) who were ventilated for greater than 24 hours and survived to discharge. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS After stratifying by traumatic brain injury diagnosis, we compared ICU and hospital length of stay, pneumonia, and discharge disposition of patients with tracheostomy prior to three cut points (3, 7, and 14 d after admission) to 1) patients intubated at least as long as each cut point and 2) patients with tracheostomy on or after each cut point. Of 11,045 patients, 1,391 (12.6%) underwent tracheostomy. Median time to tracheostomy was 9 days (interquartile range, 6-13 d) for traumatic brain injury and 7 days (interquartile range, 3-12 d) for nontraumatic brain injury patients. Nontraumatic brain injury patients with tracheostomy prior to 7 days had 5.6 fewer ICU days (-7.8 to -3.5 d) and 5.7 fewer hospital days (-8.8 to -2.7 d) than patients intubated greater than or equal to 7 days and had 14.8 fewer ICU days (-19.6 to -10.0 d) and 15.3 fewer hospital days (-21.7 to -8.9 d) than patients with tracheostomy greater than or equal to 7 days. Similar differences were observed at 14 days but not at 3 days for both traumatic brain injury and nontraumatic brain injury patients. At the 3- and 7-day cut points, both traumatic brain injury and nontraumatic brain injury patients with tracheostomy prior to the cut point had lower risk of pneumonia and risk of discharge to a facility than those with tracheostomy after the cut point. CONCLUSIONS For injured adolescents, tracheostomy less than 7 days after admission was associated with improved in-hospital outcomes compared with those who remained intubated greater than or equal to 7 days and with those with tracheostomy greater than or equal to 7 days. Tracheostomy between 3 and 7 days may be the optimal time point when prolonged need for mechanical ventilation is anticipated; however, unmeasured consequences of tracheostomy such as long-term complications and care needs must also be considered.

Abstract
Purpose To evaluate the impact of tracheostomy on complications, dysphagia and outcome in second and third degree burned patients. Methods Inpatient mortality, dysphagia, severity of burn injury (ABSI, TBSA) and complications in tracheotomized burn patients were compared to (I) non-tracheotomized burn patients and (II) matched tracheotomized non-burn patients. Results 134 (30.9%) out of 433 patients who underwent tracheostomy, had a significantly higher percentage of inhalation injury (26.1% vs. 7.0%; p < 0.001), higher ABSI (8.9 ± 2.1 vs. 6.0 ± 2.7; p < 0.001) and TBSA score (41.4 ± 19.7% vs. 18.6 ± 18.8%; p < 0.001) compared to 299 non-tracheotomized burn patients. However, complications occurred equally in tracheotomized burn patients and matched controls and tracheostomy was neither linked to dysphagia nor to inpatient mortality at multivariate analysis. In particular, dysphagia occurred in 6.2% of cases and was significantly linked to length of ICU stay (OR 6.2; p = 0.021), preexisting neurocognitive impairments (OR 5.2; p = 0.001) and patients’ age (OR 3.4; p = 0.046). A nomogram was calculated based on age, TBSA and inhalation injury predicting the need for a tracheostomy in severely burned patients. Conclusion Using the new nomogram we were able to predict with significantly higher accuracy the need for tracheostomy in severely burned patients. Moreover, tracheostomy is safe and is not associated with higher incidenc of complications, dysphagia or worse outcome.

Abstract
Abstract
Tracheocutaneous fistula (TCF) is a common complication that occurs after decannulation of a long-term tracheostomy. Numerous studies have demonstrated the incidence of TCF formation to positively correlate with an increasing duration of cannulation, specifically in children. Treatment of a persistent TCF in a child has been well described in the literature, with good response to local measures such as curettage and silver nitrate. When this fails, fistulectomy followed by primary closure of the skin or secondary intention yields good results. However, there is a lack of knowledge on TCF formation in pediatric burn-injured patients, where a persistent TCF is a particularly challenging problem to correct given the paucity of supple tissue in the neck and potential for contractures after a large burn injury; effectively making the surgical repairs and management algorithms described in the available literature largely not applicable to this patient population. In this manuscript, we describe a series of pediatric burn patients with persistent TCF, successfully treated with a multilayered closure involving local tissue rearrangement in the form of medial mobilization of the strap muscles of the neck.

Abstract
BACKGROUND There has been little systematic examination of variation in pediatric burn care clinical practices and its effect on outcomes. As a first step, current clinical care processes need to be operationally defined. The highly specialized burn care units of the Shriners Hospitals for Children system present an opportunity to describe the processes of care. The aim of this study was to develop a set of process-based measures for pediatric burn care and examine adherence to them by providers in a cohort of pediatric burn patients. METHODS We conducted a systematic literature review to compile a set of process-based indicators. These measures were refined by an expert panel of burn care providers, yielding 36 process-based indicators in four clinical areas: initial evaluation and resuscitation, acute excisional surgery and critical care, psychosocial and pain control, and reconstruction and aftercare. We assessed variability in adherence to the indicators in a cohort of 1,076 children with burns at four regional pediatric burn programs in the Shriners Hospital system. The percentages of the cohort at each of the four sites were as follows: Boston, 20.8%; Cincinnati, 21.1%; Galveston, 36.0%; and Sacramento, 22.1%. The cohort included children who received care between 2006 and 2010. RESULTS Adherence to the process indicators varied both across sites and by clinical area. Adherence was lowest for the clinical areas of acute excisional surgery and critical care, with a range of 35% to 48% across sites, followed by initial evaluation and resuscitation (range, 34%-60%). In contrast, the clinical areas of psychosocial and pain control and reconstruction and aftercare had relatively high adherence across sites, with ranges of 62% to 93% and 71% to 87%, respectively. Of the 36 process indicators, 89% differed significantly in adherence between clinical sites (p < 0.05). Acute excisional surgery and critical care exhibited the most variability. CONCLUSION The development of this set of process-based measures represents an important step in the assessment of clinical practice in pediatric burn care. Substantial variation was observed in practices of pediatric burn care. However, further research is needed to link these process-based measures to clinical outcomes.

Abstract
Smoke inhalation injury is a serious medical problem that increases morbidity and mortality after severe burns. However, relatively little attention has been paid to this devastating condition, and the bulk of research is limited to preclinical basic science studies. Moreover, no worldwide consensus criteria exist for its diagnosis, severity grading, and prognosis. Therapeutic approaches are highly variable depending on the country and burn centre or hospital. In this Series paper, we discuss understanding of the pathophysiology of smoke inhalation injury, the best evidence-based treatments, and challenges and future directions in diagnostics and management.

Abstract
Burn survival has improved with advancements in fluid resuscitation, surgical wound management, wound dressings, access to antibiotics and nutritional support for burn patients. Despite these advancements, the presence of smoke inhalation injury in addition to a cutaneous burn still significantly increases morbidity and mortality. The pathophysiology of smoke inhalation has been well studied in animal models. Translation of this knowledge into effectiveness of clinical management and correlation with patient outcomes including the paediatric population, is still limited. We retrospectively reviewed our experience of 13 years of paediatric burns admitted to a regional burn's intensive care unit. We compared critical care requirements and patient outcomes between those with cutaneous burns only and those with concurrent smoke inhalation injury. Smoke inhalation increases critical care requirements and mortality in the paediatric burn population. Therefore, early critical care input in the management of these patients is advised.
