A 17-year-old man was admitted to Accident & Emergency out of hours with unilateral tonsillar enlargement covering more than 75% of his oropharyngeal inlet. He appeared calm and stable on initial presentation, but in a short span of time rapidly deteriorated, leading to near complete airway obstruction necessitating an emergency awake cricothyroidotomy. Tracheostomy and tonsillectomy were done after this, he was ventilated postoperatively in intensive therapy unit and discharged home in a week. This is a rare clinical scenario in a patient presenting with palatine tonsillitis. A few subtle points in the history and examination alerted the team and prevented a risky inter hospital transfer for ear, nose and throat review. This is the first reported case in UK of palatine tonsillitis not due to infectious mononucleosis presenting with acute upper airway obstruction in a patient with no airway anomalies. It may also have been a varied presentation of COVID-19.
The difficult airway (DA) remains a perpetual challenge and its implications have led to multiple advances, technological and otherwise in this area. This article investigates the latest developments in the definition, prediction tools and diagnostics like airway and neck Ultrasonography (USG), Magnetic Resonance Imaging (MRI) and Computed tomography (CT) scans, preoperative Virtual endoscopy (VE) and 3D printing. Innovations in airway devices and adjuncts are analysed. Difficult airway society (DAS) guidelines, American Society of Anaesthesiologists (ASA) Practice Guidelines and Vortex approach for the management of DA are explored. Other breakthroughs include novel oxygen supplementation techniques throughout airway management and tools like Anaesthesia Information Management Systems (AIMS) and Clinical Decision Support (CDS) systems. The delivery of DA training and patient counselling has also undergone vast changes with emerging technology like Virtual Reality (VR), mobile applications and toolkits. The enormous, everevolving and endless possibilities in this area have only helped improve clinical standards and enhance patient safety.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
