Aerosol regurgitation as a laryngeal-sensitizing event explaining acute laryngospasm
- 39 Downloads
Acute laryngospasm is an incapacitating event with obscure etiology. Two cases of documented gastric aerosol regurgitation and laryngeal exposure to aerosol acid with subsequent acute laryngospasm are presented. A third individual with laryngospasm was noted to reflux gas. One individual was aware of the regurgitation etiology of the laryngospasm; the second two were not. Videofluoroscopic recording of the acute event in the second patient documented the nature of two episodes occurring within the fluoroscopy suite.
