Laryngospasm is believed to be a common cause of post-extubation airway obstruction, particularly in children.105 Even in adults, Rose and colleagues found that it accounted for 23.3% of critical postoperative respiratory events, although the diagnosis was presumptive.106 Olsson and Hallen observed an increased incidence among patients presenting for emergency surgery, those requiring nasogastric tubes, and patients undergoing tonsillectomy, cervical dilation, hypospadias correction, oral endoscopy, or excision of skin lesions.105 A variety of triggers are recognized, including vagal, trigeminal, auditory, phrenic, sciatic, and splanchnic nerve stimulation; cervical flexion or extension with an indwelling ETT; or vocal cord irritation from blood, vomitus, or oral secretions.107 A risk assessment questionnaire was used in a study to prospectively evaluate almost 10,000 children undergoing general anesthesia.

Schug, Alagirisamy Raajkumar, in Side Effects of Drugs Annual, 2008. If these measures do not result in significant improvement, intervention should include deepening of the anesthetic plane and administration of a muscle relaxant. Seizure activity changes breathing frequency, amplitude, variability, and can cause central apnea. Be vigilant, be prepared and react quickly if it occurs. This can be done either by deepening the anesthetic (with gas or IV agents) or allowing the patient to awaken to the point where the reflex stops itself. The stimulus should be removed, a change of airway should be considered, and secretions should be suctioned away. Answer = 0.3% A child with laryngospasm can be a scary thing to manage. Thank you.

[1], It is most often reported 1) post-operatively after endotracheal extubation or 2) after sudden reflux of gastric contents. Management of laryngospasm consists of prevention by either extubating at a sufficiently deep plane of anesthesia or awaiting recovery of consciousness.56 Potential airway irritants should be removed and painful stimulation should be discontinued. Richard M. Cooper, Sofia Khan, in Benumof and Hagberg's Airway Management, 2013. The infrequent, erratic and almost exclusively nocturnal occurrence and short duration of the attacks makes them hard to observe and to capture on polysomnography (Aloe and Thorpy, 1995).
