There has been a report of total airway obstruction after topical anesthesia of the larynx before fiberoptic intubation [76]. endobj If airway maneuvers do not improve ventilation, a muscle relaxant is required. Suctioning into the hypopharynx and gentle application of oxygen under positive pressure are initial treatments. My recommendation would be to ask for referral to a head and neck specialist. When it happens, the vocal cords suddenly seize up or close when taking in a breath, blocking the flow of air into the lungs.

No differences were found among bradycardia, cardiac arrest, and death outcomes. Laryngospasm, as we discussed, occurs with airway stimulation in stage 2 of anesthesia, when the airway reflexes are heightened and the reflexes arc that tends to turn off or dampen those protective reflexes is not quite restored to normal. There are 3 major types of laryngeal movement. If these measures do not result in significant improvement, intervention should include deepening of the anesthetic plane and administration of a muscle relaxant.
