We report an unusual case of acute upper airway obstruction. Inhalation of a foreign body caused choking in a 5-yr-old child, but subsequent investigations revealed a large anterior mediastinal tumour, externally compressing the trachea and the main bronchi. Such a presentation may be deceptive and is important, as general anaesthesia may result in complete airway obstruction with fatal consequ...

Acute upper airway obstruction may occur secondary to hematoma formation following traumatic internal jugular vein (IJV) cannulation. Though uncommon, hematoma after central access can be a life-threatening event that requires early and prompt intervention. We present two different cases of airway obstruction caused by hematoma formation following IJV central line placement and discuss key mana...

Congenital high airway obstruction syndrome (CHAOS) is the obstruction of the fetal upper airways, which may be partial or complete. It is important to diagnose it antenatally as it is uniformly lethal and leads to stillbirth or death shortly after delivery. Antenatal diagnosis is made by identifying echogenic and enlarged lungs, dilated bronchi, inverted /flattened diaphragm and ascites on ult...

Obstructive sleep apnea hypopnea syndrome (OSAHS) is apnea and hypoventilation caused by upper airway collapse during sleep, accompanied by snoring, disrupted sleep structure, frequent occurrence of oxygen desaturation and daytime sleepiness [1,2]. OSAHS has a rather high prevalence and can cause systemic and multi-system damages. Hence, it has received increasing attention in recent years. The...
