Background: Ingestion of alkaline substances can cause mucosal damage and upper airway obstruction. This is a serious and potentially fatal complication that occurs within the first few hours after ingestion. There has been no established algorithm for emergent airway management in these situations. We present a case of difficult airway management in a patient with upper airway obstruction caused by alkali ingestion, wherein we opted for intubation with video laryngoscopy and successfully treated the patient.Case presentation: An 80-year-old patient accidentally ingested a small amount of alkaline liquid and presented to our hospital with complaints of burning sensation in the throat. Within two hours of arrival at the hospital, the edema in the epiglottis rapidly worsened, resulting in upper airway obstruction. Assuming that intubation and ventilation would be difficult in this situation, we attempted to intubate the patient using fiberoptic bronchoscopy, but it was difficult. Finally, after two unsuccessful attempts, we successfully intubated the patient using a video laryngoscope.Conclusions: The patient in our case had acute upper airway obstruction due to alkali ingestion, which caused difficulty in tracheal intubation. Our experience, in this case, would likely help emergency physicians to intubate more safely in patients with emergent upper airway obstruction due to alkali ingestion. For intubation in such situations, it would be a reasonable option to use video laryngoscopy.
BackgroundNasogastric tube syndrome is a rare but life‐threatening complication of nasogastric tube placement due to acute upper airway obstruction caused by bilateral vocal cord paresis.Case PresentationAn 86‐year‐old woman was brought to the emergency department with acute stridor. She had been diagnosed with stroke 106 days prior, and an 8F nasogastric tube was placed on the day following the diagnosis. A laryngeal fiberscopy revealed bilateral laryngeal edema and bilateral vocal cord palsy. Nasogastric tube removal and intubation were carried out, and the stridor disappeared. Two days later, a tracheostomy was performed. Unfortunately, the patient's vocal cord function had not improved at the 1 month follow‐up upon assessment with a laryngeal fiberscope.ConclusionLong‐term small‐bore nasogastric tube placement can cause upper airway obstruction due to bilateral vocal cord palsy.
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.
