Plant poisoning, although rare, should be considered for a diagnosis in children when the symptoms of angioedema and/or sudden onset of airway obstruction are present.
Sedation levels were estimated by using Ramsay scoring and the Bispectral Index.[17] The degree of airway obstruction was assessed using the airway obstruction score (AOS),[18],[19] a test of the adequacy of positive pressure ventilation through facemask (difficult ventilation test) was done between spontaneous breaths and measured using Han's Mask Ventilation Score.[20],[21] If AOS <2 or the Han score <3, sevoflurane inhalation was kept at 3% until the loss of consciousness.
The authors of this manuscript have developed a novel method for using nasal trumpets (Double Barrel Technique and Modified Double Barrel Technique) to help prevent upper airway obstruction after surgery even if the patients have had nasal surgery.
Fourteen case reports of airway obstruction secondary to subcutaneous emphysema have been identified in the English literature including spontaneous, surgical, and trauma cases [8-20].

Congenital high airway obstruction syndrome is characterised by a dilated trachea, hyperechoic lungs, fattened diaphragm, foetal ascites and polyhydramnios on the antenatal care scan (1).
The present report showed that the electrocautery using hot biopsy forceps is a potential useful technique to manage carcinomatous central airway obstruction. Previous studies have demonstrated that high-frequency wire snares are useful devices for bronchoscopic electrocautery [3, 4].
While most such tongue lesions do not cause any complications, palatopharyngeal masses are frequently symptomatic and sometimes life-threatening because of potential airway obstruction and serious feeding problems, especially in neonates.
Flexible laryngoscopy revealed large bilateral vocal cord polyps causing almost complete airway obstruction. The findings of such extensive polyps on laryngoscopy implied a potentially longer clinical course than originally reported.
The nasal valve contributes as much as 80% of total nasal airway resistance, and even minor constriction of this area results in a clinically significant impairment of nasal breathing for the patient.4 Nasal valvular incompetence may equal or even exceed septal deviation as the prime cause of nasal airway obstruction.
Rozanski and Chan (2005) reported that dogs with upper airway obstruction are initially presented with hyperthermia.
