BACKGROUND
Anesthesia remains challenging for bronchoscopic tracheobronchial surgeries (BTS) involving surgical manipulations for central airway obstruction within shared airways. To provide complete airway use through intervention with spontaneous breathing without endotracheal tubes, monitored non-intubated anesthesia has been successfully applied with electroencephalogram-derived monitored total intravenous anesthesia. This study evaluated the feasibility and the outcomes of BTS with monitored non-intubated anesthesia. The factors associated with desaturation and complications were also analyzed.
METHODS
Data from patients receiving non-intubated BTS performed between October 2019 and August 2022 were retrospectively collected. Intraoperative results and postoperative outcomes were analyzed.
RESULTS
Data of 92 patients were collected. Supraglottic airways devices and high-flow nasal oxygen were used in 68 and 24 patients respectively. Surgery was successfully completed in 87 patients (94.6%), whereas three patients required conversion to intubation because of substantial bleeding. In total, 11% of patients experienced desaturation [oxygen saturation (SpO) <90%] for an average of 9 minutes. Unexpected admission to the intensive care unit (ICU) occurred in 12.2% (5/41) of patients from outpatient department and 7.8% (4/51) of hospitalization settings because of high-grade surgical bleeding. With comparable desaturation incidence, tracheal surgery had significantly longer desaturation times (14.5±6.9 min) than bronchial surgeries (5.8±2.6 min) did.
CONCLUSIONS
Monitored non-intubated anesthesia with spontaneous breathing is feasible for BTS, with high success rate, few complications, and rapid recovery. High-grade bleeding remains the most unpredictable risk for intraoperative desaturation and postoperative ICU admission, especially in tracheal obstruction cases.

INTRODUCTION
Foreign bodies in the airways can cause significant morbidity and mortality. If emergency personnel are unable to clear an airway obstruction frequently results in cardiac arrest.
PATIENT CONCERNS
A 78-year-old man developed a persistent cough and dyspnoea after consuming alcohol. Fiberoptic bronchoscopy was performed, revealing complete blockage of the main airways on both sides by fish.
DIAGNOSIS
Endotracheal foreign body.
INTERVENTIONS
The foreign body was removed with an endotracheal tube under the guidance of a fiberoptic bronchoscope.
OUTCOMES
The airway foreign body had been successfully removed and the man recovered uneventfully.
CONCLUSION
When repeated attempts to extract airway foreign bodies under the guidance of bronchoscopy have failed, endotracheal intubation can be considered as a viable alternative in emergency situations.

Anomalous mitral arcade (MA) is a rare congenital anomaly. We report a case of MA in a newborn who presented with hydrops fetalis due to severe mitral regurgitation. After birth, he developed severe respiratory failure, congestive heart failure and airway obstruction because an enlarged left atrium from severe mitral regurgitation compressed the distal left main bronchus. There is limited experience in surgical management of this condition in Thailand, and the patient's mitral valve was too small for replacement. Therefore, he was treated with medication to control heart failure and supported with positive pressure ventilation to promote growth. We have followed the patient until the current time of writing this report at the age of 2 years, and his outcome is favourable regarding heart failure symptoms, airway obstruction, growth and development. This case describes a challenging experience in the non-surgical management of MA with severe regurgitation, which presented at birth.

We report a case of a cannulated nasopharyngeal airway (NPA) in a patient having a neurological deficit, absent gag reflex, and no clinically obvious signs of respiratory distress. The patient had two episodes of vomiting before admission and was admitted with the initial working diagnosis of aspiration pneumonia; however, a preliminary chest X-ray (CXR) revealed an NPA, sitting vertically in the airway. It is our emphasis that thorough clinical history and radiological imaging are of paramount importance in prompt management of such airway complications.

Foreign body aspiration (FBA) is a significant cause of accidental death among children, with laryngeal FBA being relatively rare but potentially fatal due to airway obstruction. This report highlights a case of laryngeal FBA in an 11-month-old child, initially misdiagnosed as viral croup. Otolaryngological evaluation, particularly in the case of laryngeal FBA, may facilitate management. An 11-month-old male was brought to the emergency department, presenting with inspiratory stridor following a choking episode. A chest radiograph and CT scan of the chest were read as normal. He was suspected of having croup and treated with dexamethasone and racemic nebulized epinephrine, which led to temporary clinical improvement. The child returned with persistent stridor to the emergency department eight days after his initial visit, prompting an otolaryngological consultation. Flexible laryngoscopy ultimately identified a star-shaped sequin lodged in the glottis. The foreign body was successfully removed via direct laryngoscopy and bronchoscopy (DLB). Following the removal, the patient demonstrated significant improvement and eventually made a full recovery. This case emphasizes the difficulty in diagnosing laryngeal FBA due to its non-specific symptoms and the limitations of imaging techniques. The importance of a thorough clinical history, physical examination, and proper imaging combined with a high index of suspicion is crucial for early diagnosis and treatment. Additionally, the report discusses the potential for severe complications if diagnosis and treatment are delayed, highlighting the need for awareness and prompt intervention in suspected laryngeal FBA cases.

OBJECTIVE
A low expression of club cell secretory protein (CC16) and high levels of proinflammatory cytokines at preterm birth are associated with airway inflammation and more severe neonatal lung disease. The present study aimed to investigate if low levels of CC16, proinflammatory cytokines and vascular endothelial growth factors (VEGF) in tracheal aspirate early after birth were associated with lung function impairment at school age.
PATIENTS AND METHODS
Participants were 20 children, born very preterm (median gestational age 25+3 weeks+days, IQR: 24+1-27+0 weeks+days), who had tracheal aspirates collected during mechanical ventilation in their first day of life. CC16, cytokines, VEGF and matrix metalloproteinase-9 were measured in the tracheal aspirate and later correlated to results from advanced lung function measurements at 12 years of age.
RESULTS
Low levels of CC16 and high levels of the proinflammatory cytokines IL-1β and TNF-α in tracheal aspirate were associated with airway obstruction at school age but not with other lung function parameters. The correlation with airway obstruction was even stronger when the ratio between the respective proinflammatory cytokine and CC16 was used. In addition, low levels of VEGF and CC16 were associated with impaired diffusion capacity of the lung.
CONCLUSIONS
An imbalance in inflammatory mediators and growth factors in the lungs at birth may have consequences for airway function and vasculature at school age in preterm born children.

BACKGROUND
The aim of the study was to provide insight into the influence of the COVID-19 on the frequency and characteristics of urgent and emergent tracheostomies (TS), comparing data collected both before and during the pandemic. Our two hypotheses were that and that .
PATIENTS AND METHODS
The research was retrospective. The study period included the two years before and after the COVID-19 outbreak in Slovenia. Forty-one patients in each period met the inclusion criteria. Their medical charts were reviewed. The anamnestic, clinical, surgical and anaesthesiological data were collected. The two groups of patients from corresponding time periods were statistically compared.
RESULTS
Predominantly men required the surgical resolution of acute upper airway obstruction (76% of patients). The causes for acute respiratory distress included head and neck cancer (62%), infections (20%), vocal cord paralysis (16%), and stenosis (2%). There were no statistically significant differences either in the (emergent/urgent) setting of TS or in the type of anaesthesia used. Both hypotheses were rejected. A statistically significant rise in use of the C-MAC laryngoscope during COVID-19 (from 3% to 15%) was reported.
CONCLUSIONS
The outbreak of COVID-19 did not have a statistically significant effect on the frequency of performing emergent and urgent tracheostomies nor on the use of general or local anaesthesia. It did, however, require a change of intubation technique. Consequently, a significant rise in the use of the C-MAC laryngoscope was noted.

BACKGROUND
Small airways obstruction (SAO) has been associated with occupational exposures. Whether exposure to harmful occupational agents impacts the survival of people with SAO is unknown. Our aim was to estimate the mortality risk associated with occupational exposures among people with SAO.
METHODS
We used data from UK Biobank participants with SAO, defined as a ratio of forced expiratory volume in three seconds to forced expiratory volume in six seconds (FEV3/FEV6) below the lower limit of normal. We assigned lifetime occupational exposures to participants with available occupational histories using the ALOHA+ Job Exposure Matrix. Mortality data were provided by the National Death Registries. We used Cox regression to assess the association of all-cause mortality with lifetime occupational exposures (vapours, gases, dusts, fumes-VGDF; solvents; pesticides; metals), adjusting for potential confounders.
RESULTS
The 13,942 participants with SAO had a mean age of 56±7 years, 59% were females and 94.2% were of White ancestry. Overall, there were 457 deaths over a median follow-up of 12.8 years. A greater mortality risk was associated with exposure to VGDF, with hazard ratios of 1.32 (95%CI: 1.04-1.78) for low levels and 1.41 (95%CI: 1.11-1.78) for moderate levels of cumulative exposure. There was no evidence of association for the other occupational exposures.
CONCLUSION
Lifetime occupational exposure to VGDF in people with SAO may have a detrimental effect on their survival. Future respiratory health surveillance programmes of people exposed to VGDF should consider assessment for SAO and focus on primary prevention through adequate exposure control.

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.
