RESUMEN
El estridor es un síntoma de obstrucción de la vía aérea superior y puede ser resultado de causas congénitas o adquiridas. El diagnóstico suele ser clínico. Si es necesaria una investigación adicional para el diagnóstico diferencial, la endoscopia es el método de elección en la mayoría de los casos. Los estudios por imágenes son complementarios a la endoscopia. Permiten evaluar la patología laríngea y traqueobronquial, las compresiones extrínsecas de la vía aérea por tumores o malformaciones vasculares y definir la localización, extensión y características de una lesión. Son útiles en casos de duda diagnóstica y cuando la endoscopia no está disponible. Es fundamental comprender la anatomía y fisiopatología del tracto respiratorio, y ser conscientes de las indicaciones y limitaciones de los exámenes complementarios para el diagnóstico adecuado. Se describen las diferentes modalidades de imágenes disponibles para evaluar el estridor en pediatría y se discuten sus ventajas.
Stridor is a symptom of upper airway obstruction and may result from congenital or acquired causes. The diagnosis is usually clinical. If further investigation is necessary for differential diagnosis, endoscopy is the method of choice in most cases. Imaging studies are complementary to endoscopy. They allow evaluation of laryngeal and tracheobronchial pathology and extrinsic airway compressions due to tumors or vascular malformations and define a lesion's location, extent, and characteristics. They are helpful in cases of diagnostic doubt and when endoscopy is unavailable. It is essential to understand the anatomy and pathophysiology of the respiratory tract and to be aware of the indications and limitations of complementary examinations for proper diagnosis. The different imaging modalities available to evaluate stridor in pediatrics are described, and their advantages are discussed.

OBJECTIVE: The aim of this study was to describe the phases of a decannulation protocol and the results from its application in hospitalized children. METHODS: This is a retrospective, observational study. Data were collected from medical records of decannulated patients followed up in a pediatric hospital in Belo Horizonte, Minas Gerais between 2011 and 2021. RESULTS: Among the children followed up in the service (n=526), 23% (n=120) were successfully decannulated. Children aged between 2 months and 16 years, with a mean age of 4 years, 69% of whom were male, were evaluated. About 75% of the patients have tracheostomy due to upper airway obstruction and 60% of these due to acquired subglottic stenosis. At the beginning of the decannulation protocol, 5.5% of the patients had moderate oropharyngeal dysphagia, while 80.4% had normal swallowing. Correction in the upper airway pre-decannulation was performed in 39.5% of the patients, dilation in 63.8%, and endoscopic correction was performed in 55.3%. After performing the decannulation, none of the patients had complications. CONCLUSIONS: The described decannulation protocol is safe, since no complications such as death and need for recannulation happened.

La bronquitis plástica es una enfermedad infrecuente y poco estudiada. Se caracteriza por la obstrucción parcial o total de la vía aérea inferior por moldes o yesos gomosos y firmes, compuestos por múltiples sustancias como fibrina, mucina y otros, que se acumulan en la luz bronquial. En la actualidad, no hay un consenso de la fisiopatología real. Puede presentarse con síntomas leves como tos, sibilancias y disnea, hasta eventos fatales de insuficiencia respiratoria. Se clasifican en tipo I (inflamatorios) y tipo II (acelulares). La presencia de la bronquitis plástica es una complicación de varias enfermedades y está relacionada con procedimientos correctivos de cardiopatías congénitas (procedimiento de Fontan). El diagnóstico se hace a través de la identificación de los yesos bronquiales, ya sea cuando el paciente los expectora o por broncoscopía. Se han utilizado múltiples terapias que solo tienen evidencias anecdóticas. En los últimos años se han observado buenos resultados con el uso de heparinas, así como el alteplasa nebulizado e instilado por broncoscopia.
Plastic bronchitis is a rare and little-studied disease. It is characterized by partial or total obstruction of the lower airway by rubbery and firm molds or plasters, made up of multiple substances that accumulate in the bronchial lumen. Currently, there is no consensus on real pathophysiology. It can present itself with mild symptoms such as cough, wheezing and dyspnea, to fatal events of respiratory failure. They are classified into type I (inflammatory) and type II (acellular). The presence of plastic bronchitis is a complication of several diseases and in corrective procedures for congenital heart disease (Fontan procedure). Diagnosis is made by identifying bronchial casts, either by the patient expectorating them or by bronchoscopy. Multiple therapies have been used that only have anecdotal evidence. In recent years, good results have been observed with the use of heparins and tPA nebulized and instilled by bronchoscop.

BACKGROUND: In 2013, a new predictor of successful mechanical ventilation liberation named timed inspiratory effort (TIE) index was devised with the normalization of the maximum inspiratory pressure (obtained within 60 s of unidirectional airway occlusion) with the time at which the value was reached. The aim of this study was to verify whether the presence of a sequence of a certain number of inspiratory effort values between 30-60 s > 1.0 cm H2O/s could predict weaning success in a performance comparable to the TIE index. METHODS: This was a retrospective observational study using 4 databases of previous studies on the TIE index. All patients receiving mechanical ventilation for ≤ 24 h were eligible. Liberation from mechanical ventilation-extubation decisions was made based on performance with spontaneous breathing trials. P < .05 was considered significant. The performance of the TIE index was evaluated by calculating the area under the receiver operating characteristics (AUROC) curve. RESULTS: From 349 eligible patients, 165 subjects were selected for analysis. The AUROC for the TIE index in the studied sample was 0.92 (95% CI 0.87-0.97, P < .001). A sequence of ≤ 4 inspiratory efforts > 1.0 cm H2O/s was found in 51.5% of the subjects, with successful ventilatory liberation occurring in 95.3%. The highest specificity values belonged to the sequence of ≤ 4 and ≤ 5 inspiratory efforts > 1.0 cm H2O/s; the highest positive predictive value and positive likelihood ratio belonged to the sequence of ≤ 4 inspiratory efforts > 1.0 cm H2O/s. The mean time that could have been spared if the procedure were interrupted after the first sequence of 4 inspiratory efforts > 1.0 cm H2O/s was 23 ± 3 s. CONCLUSIONS: The presence of a sequence of ≤ 4 inspiratory efforts > 1.0 cm H2O/s during the TIE index measurement was a reliable predictor of weaning success, which could allow timely interruption of the procedure and entail a substantial reduction in airway occlusion time.

OBJECTIVE: To describe the spectrum of disease and burden of care in infants with congenital micrognathia from a multicenter cohort hospitalized at tertiary care centers. STUDY DESIGN: The Children's Hospitals Neonatal Database was queried from 2010 through 2020 for infants diagnosed with micrognathia. Demographics, presence of genetic syndromes, and cleft status were summarized. Outcomes included death, length of hospitalization, neonatal surgery, and feeding and respiratory support at discharge. RESULTS: Analysis included 3,236 infants with congenital micrognathia. Cleft palate was identified in 1266 (39.1%). A genetic syndrome associated with micrognathia was diagnosed during the neonatal hospitalization in 256 (7.9%). Median (IQR) length of hospitalization was 35 (16, 63) days. Death during the hospitalization (n = 228, 6.8%) was associated with absence of cleft palate (4.4%, P < .001) and maternal Black race (11.6%, P < .001). During the neonatal hospitalization, 1289 (39.7%) underwent surgery to correct airway obstruction and 1059 (32.7%) underwent gastrostomy tube placement. At the time of discharge, 1035 (40.3%) were exclusively feeding orally. There was significant variability between centers related to length of stay and presence of a feeding tube at discharge (P < .001 for both). CONCLUSIONS: Infants hospitalized with congenital micrognathia have a significant burden of disease, commonly receive surgical intervention, and most often require tube feedings at hospital discharge. We identified disparities based on race and among centers. Development of evidence-based guidelines could improve neonatal care.

As doenças respiratórias são consideradas doenças graves e potencialmente deletérias. Dentre elas, a asma e a bronquite crônica caracterizam-se como disfunções respiratórias que ameaçam constantemente o bem-estar dos gatos. Os pacientes apresentam mudanças na estrutura respiratória, reversíveis ou não, devido ao extenso quadro inflamatório, que obstrui o fluxo de ar, permite o acúmulo de muco e reduz o lúmen das vias aéreas. Os gatos acometidos apresentam tosses, respiração ruidosa, dispneia, e, em muitos casos, assumem posição ortopneica. O diagnóstico pode ser obtido através de exames de rotina, uso de radiografias torácicas, coleta e análise de fluidos broncoalveolares, e testes alergênicos. O manejo terapêutico baseia-se, combinado ou não, no uso de drogas como broncodilatadores, antiinflamatórios esteroidais, mucolíticos, antibióticos, agentes inalatórios e mudanças ambientais com objetivo de redução da exposição aos possíveis agentes alergênicos responsáveis pela incitação do quadro respiratório.
Respiratory diseases are considered serious and potentially harmful diseases. Among them, asthma and chronic bronchitis are characterized as respiratory disorders that constantly threaten the well-being of cats. The patients present changes in the respiratory structure, reversible or not, due to the extensive inflammatory condition, which obstructs the air flow, allows the accumulation of mucus and reduces the lumen of the airways. Affected cats have coughs, wheezing, dyspnoea, and in many cases assume an orthopneic position. The diagnosis can be obtained through routine exams, use of chest x-rays, collection and analysis of bronchoalveolar fluids, and allergen testing. Therapeutic management is based, combined or not, on the use of drugs such as bronchodilators, steroidal anti-inflammatory, mucolytics, antibiotics, inhalational agents and environmental changes in order to reduce exposure to possible allergenic agents responsible for the incitation of the respiratory condition.

PURPOSE OF REVIEW: This review provides an overview of the evolving field of airway stenting (AS), highlighting its relevance in the management of central airway obstruction (CAO). It discusses recent advancements, including 3D-printed silicone stents (3DPSS), metallic stents, biodegradable stents (BS), and drug-eluting stents (DES), which are transforming clinical practice. The review underscores the ongoing challenges in patient selection, stent choice, and long-term management in the context of an evolving landscape. RECENT FINDINGS: Innovations, particularly 3DPSS, have shown promise in providing patient-specific solutions. These stents offer improved symptom relief, enhanced quality of life, and lower complication rates, especially for complex airway diseases. The use of BS and DES is explored, raising prospects for future applications. SUMMARY: The evolution of AS reflects a deepening understanding of airway obstructions. Recent innovations, such as 3DPSS, BS, and DES, show considerable promise in addressing the limitations of conventional stents. However, challenges related to complications, patient selection, and long-term management persist, demanding further research. Wide practice variations in the management of AS highlight the need for more clinical data and standardized guidelines. The search for the ideal stent continues, driven by the pursuit of better outcomes for patients with CAO.

O sangramento e a obstrução das vias aéreas no câncer de cabeça e pescoço são as principais causas de morte e grande parte dos pacientes com doença localmente avançada necessitam de controle das vias aéreas em algum momento. O grau de estenose para gerar resistência à passagem de ar é de 50% e a causa mais comum de obstrução é o câncer de laringe, por ser o ponto mais estreito das vias aéreas, seguido por tumores da cavidade oral, orofaringe e hipofaringe, sendo a terceira causa a compressão extrínseca do linfoma e câncer anaplásico da tireoide. As causas benignas incluem complicações pós-cirúrgicas como hematomas, aspiração, obstrução por reconstruções volumosas na cavidade oral ou na base da língua e lesão do nervo laríngeo recorrente. A abordagem da via aérea em cirurgias oncológicas de cabeça e pescoço pode constituir um importante desafio para os anestesiologistas, principalmente nos procedimentos de urgência. A maioria dos tumores de cabeça e pescoço possui associação com o tabagismo e etilismo, o que também predispõe a doenças cardiopulmonares e hepáticas nessa população. A tomada de decisão em relação à técnica anestésica mais segura é particularmente complexa em casos de câncer de tireoide avançado devido à sua posição anatômica anterior à traqueia. A traqueostomia com abordagem transtumoral é um desafio para ambas as equipes. O manuseio anestésico promove uma via aérea segura para posteriormente iniciar a abordagem cirúrgica da traqueostomia transtumoral. Este relato de caso tem como objetivo descrever a abordagem segura da via aérea utilizando a broncofibroscopia em um paciente com diagnóstico de carcinoma papilífero de tireoide em estágio avançado pela equipe de anestesia
Bleeding and airway obstruction in head and neck cancer are the main causes of death and most patients with locally advanced disease develop airway control at some point. The degree of stenosis to generate resistance to air passage is 50% and the most common cause of obstruction is laryngeal cancer, as it is the narrowest point in the airways, followed by tumors of the oral cavity, oropharynx and hypopharynx. The third cause is the extrinsic update of lymphoma and anaplastic thyroid cancer. Benign causes include post-surgical complications such as hematomas, aspiration, obstruction due to bulky reconstructions in the oral cavity or base of the tongue, and injury to the recurrent laryngeal nerve. Approaching the airway in head and neck oncological surgeries can represent an important challenge for anesthesiologists, especially in emergency procedures. Most head and neck tumors are associated with smoking and alcohol consumption, which also predisposes to cardiopulmonary and liver diseases in this population. Decision-making regarding the safest anesthetic technique is particularly complex in cases of advanced thyroid cancer due to its anatomical position anterior to the trachea. Tracheostomy with a transtumoral approach is a challenge for both teams. The relative anesthetic promotes a safe airway to subsequently initiate a surgical approach to transtumoral tracheostomy. This case report aims to describe the safe approach to the airway using bronchoscopy in a patient diagnosed with advanced stage papillary thyroid carcinoma by the anesthesia team

La Sociedad Americana de Anestesiología (ASA) define vía aérea difícil, como la situación clínica en la que un médico capacitado en el cuidado anestésico experimenta una dificultad anticipada o no, incluyendo uno o más de los siguientes: ventilación con máscara facial, laringoscopia, ventilación mediante una vía aérea supraglótica, intubación traqueal, extubación o vía aérea invasiva. El manejo de vía aérea difícil sigue siendo un reto incluso para expertos en su manejo y más aún si esta se realiza en lugares poco controlados, con escaso equipamiento y con personal sin entrenamiento adecuado. El objetivo de este trabajo es dar a conocer una opción segura en el abordaje del paciente que presenta vía aérea difícil. Presentamos el caso de un paciente masculino, 73 años, llevado a emergencia por dificultad respiratoria secundario a una obstrucción parcial de la vía aérea debido a una masa gigante en cuello, donde se realiza intubación traqueal vigil videoasistida con sedación (ketamina y dexmedetomidina). El paciente con gran parte de su vía aérea invadida por la masa, se preoxigena a través de un dispositivo bolsa- mascarilla previo a intubación orotraqueal, manteniendo la ventilación espontánea con asociado a sedación monitorizada; evitando así un evento fatídico como ser el colapso de la vía aérea. En conclusión, la intubación traqueal vigil videoasistida bajo sedación con ketamina y dexmedetomidina es una opción segura en abordaje de vía aérea difícil...(AU)

Las neoplasias de la tráquea son poco comunes, siendo más infrecuente aún el linfoma de células B no Hodgkin a este nivel. La presentación clínica de esta entidad es muy variable y sus síntomas son muy inespecíficos, simulando varias enfermedades, generando así un diagnóstico tardío. Actualmente se dispone de varias ayudas diagnósticas que permiten descartar otras patologías y confirmar la neoplasia traqueal, además la biopsia es fundamental para llegar al diagnóstico final y así instaurar el manejo en estadios tempranos, para impactar en la morbimortalidad. A continuación presentamos el caso de una paciente con linfoma de células B no Hodgkin como causa de obstrucción traqueal.
Tracheal neoplasms are uncommon, with non-Hodgkin B-cell lymphoma being even rarer at this level. The clinical presentation of this entity is highly variable and its symptoms are very non-specific, simulating several diseases, thus generating a late diagnosis. Currently, there are several diagnostic aids that allow us to rule out other pathologies and confirm tracheal neoplasia, in addition, biopsy is essential to reach the final diagnosis and thus establish management in early stages to impact morbidity and mortality. We present the case of a patient with non-Hodgkin's B-cell lymphoma as a cause of tracheal obstruction.

INTRODUCTION: The aim of the study is to evaluate major causes of upper airway obstruction in newborns receiving healthcare at our institution, their method of endoscopic assessment and the rate of complications related to these procedures. MATERIALS AND METHODS: This is a case series study of patients from institutional neonatal intensive care unit (NICU) presenting signs of ventilatory dysfunction for whom an endoscopic airway assessment was warranted. Information of interest was collected from medical records according to a Clinical and Endoscopic Assessment Protocol created for the study. The protocol included clinical manifestations needing ENT evaluation, clinical signs of ventilatory dysfunction, comorbidities (pulmonary, cardiac, neurological, and gastrointestinal), examination method (airway endoscopy under general anesthesia or awake), exam complications, and final diagnosis. RESULTS: One hundred sixty-nine newborn patients who underwent airway endoscopy (awake bedside flexible fiberoptic laryngoscopy (FFL) or direct laryngoscopy and bronchoscopy (DLB) in the surgical ward) were included. Thirty-nine patients (23.07%) underwent bedside FFL. For the remaining 130 who underwent DLB under general anesthesia, the median procedure time was 30 min (20-44). Only 9 (5.32%) patients presented complications: desaturation (4), laryngospasm without desaturation with spontaneous resolution (2), apnea with resolution after stimulation (1), seizures (1), nasal bleeding (1). The most frequent diagnoses found were glossoptosis, posterior laryngeal edema, and laryngomalacia. CONCLUSION: This retrospective case series describes the prevalence of different pathologies that cause upper airway obstruction in neonates. Airway endoscopy seems an effective and safe diagnostic tool in neonatal airway obstruction. Glossoptosis was the most prevalent cause of obstruction in our center.

INTRODUCTION: Large congenital neck tumors can cause neonatal death due to airway obstruction. The aim of this study was to report outcomes of the first cohort of fetuses with neck masses and suspected airway obstruction managed with fetal laryngoscopy (FL) and fetal endoscopic tracheal intubation (FETI) to secure fetal airways and avoid ex utero intrapartum treatment (EXIT) procedure. METHODS: A prospective observational cohort of consecutive fetuses with neck masses that were candidates for an EXIT procedure due to suspicion of laryngeal and/or tracheal occlusion on ultrasonographic (US) or magnetic resonance imaging (MRI) examination were recruited for FL in a tertiary referral center in Queretaro, Mexico. FETI was performed if the obstruction was confirmed by FL. Maternal and perinatal outcomes were evaluated. RESULTS: Between January 2012 and March 2023, 35 cases with neck masses were evaluated. Airway obstruction was suspected in 12/35 (34.3%), either by US in 10/35 (28.6%) or by fetal MRI in 2/35 (5.7%). In all cases, FL was successfully performed at the first attempt at a median gestational age (GA) of 36+5 (range, 33+5-39+6) weeks+days, with a median surgical time of 22.5 (12-35) min. In 4 cases, airway patency was confirmed during FL and an EXIT procedure was avoided. In 8/12 cases (66.7%), airway obstruction was confirmed during fetoscopy and FETI was successfully performed at a median GA of 36+3 (33+2-38+5) weeks+days, with a median surgical time of 25.0 (range, 12-45) min. No case required an EXIT procedure. All patients underwent conventional cesarean delivery with no maternal complications and all neonates were admitted to the neonatal intensive care unit with a correctly positioned endotracheal tube (ETT) immediately after delivery. Three neonatal deaths (37.5%) were reported due to postnatal unplanned extubation, failed ETT replacement, and tumoral bleeding. CONCLUSION: In fetuses with neck masses and suspected airway obstruction, FL and FETI are feasible and could replace EXIT procedures with good maternal and perinatal outcomes.

OBJECTIVE: Compare the occurrence of choking and gagging in infants subjected to three complementary feeding (CF) methods. METHODS: Randomized clinical trial with mother-infant pairs, allocated according to the following methods of CF: a) Parent-Led Weaning (PLW) - group control, b) Baby-Led Introduction to SolidS (BLISS), and c) mixed (initially BLISS and if the infant presents a lack of interest or dissatisfaction, PLW), with the last two methods guided by the infant. Mothers received nutritional intervention on CF and prevention of choking and gagging according to the method at 5.5 months of age and remained in follow-up until 12 months. Frequencies of choking and gagging were collected by questionnaire at nine and 12 months. The comparison between groups was performed using the analysis of variance test (p < 0.05). RESULTS: 130 infants were followed, and 34 (26.2%) children presented choking between six and 12 months of age, 13 (30.2%) in PLW, 10 (22.2%) BLISS, and 11 (26.2%) mixed method, no significative difference between methods (p > 0.05). The choking was caused mainly by the semi-solid/solid consistency. Moreover, 100 (80%) infants aged from six to 12 months presented gagging and their characteristics were not statistically different among groups (p > 0.05). CONCLUSION: Infants following a baby-led feeding method that includes advice on minimizing choking risk do not seem more likely to choke than infants following traditional feeding practice that includes advice on minimizing choking risk.

OBJECTIVE: To analyze the contributions of telesimulation to the knowledge of mothers faced with foreign body airway obstruction in children under 1 year of age and identify the related factors. METHODS: A quasi-experimental study of the pre- and post-test design carried out between April and September 2021 with 49 mothers from a city in São Paulo. It was organized into four stages: pre-test, telesimulation, immediate and late post-test (60 days later). All steps were carried out remotely via the free online platform Google Hangouts® and Google Forms®. Data analyzed by descriptive and analytical statistics. RESULTS: There was a significant difference in the knowledge score between the assessments (p<0.001). Statistically significant relationships were identified between pre-test knowledge and choking experience (p=0.012), promotion of immediate knowledge and another child's choking (p=0.040) and schooling (p=0.006) and promotion of late knowledge with occupation (p=0.012) and choking of another child (p=0.011). CONCLUSIONS: There was a significant improvement in knowledge after telesimulation, especially among those who had never experienced a choking situation and had a higher level of education.
