It occurs during general or local anesthesia, natural sleep (rapid eye movement phase of sleep), hypercapnia, and hypoxia, as well as various muscular, neuromuscular junction, or peripheral nerves disorders affecting the efferent neural pathway and effector organs of upper airway reflexes.19, This condition arises as a result of an exaggerated and prolonged laryngeal closure reflex that can be triggered by mechanical (manipulation of pharynx or larynx) or chemical stimuli (e.g. This website uses cookies to improve your experience while you navigate through the website. Immediately after extubation, the patient developed inspiratory stridor consistent with laryngospasm; the anesthesiologist had difficulty in mask ventilating the patient, and peripheral oxygen saturation decreased to less than 80%. Sufentanil (1 mcg) was given intravenously and the surgeon was allowed to proceed 5 min later. Such a conservative attitude has already been proposed for otolaryngology patients, whose surgery is expected to have an effect on the recurrence of URI episodes.11Premedication with anticholinergic agents may decrease secretions but has no demonstrated influence on the incidence of laryngospasm.7,29. #mc-embedded-subscribe-form input[type=checkbox] { Last reviewed by a Cleveland Clinic medical professional on 02/11/2022. However, onset time to effective relief of laryngospasm is shorter than onset time to maximal twitch depression, enabling laryngospasm relief and oxygenation (within 60 s) in less time than time to maximum twitch depression.55Therefore, intramuscular succinylcholine is the best alternative approach if IV access is not readily available.56Another alternative for succinylcholine administration is the intraosseous route. However, a systematic approach based on the model of translational research has recently been proposed in medical education.79In this model, successive rigorous studies are conducted to evaluate the acquisition of skills and knowledge at different outcome levels.

To reverse laryngospasm after surgery with anesthesia, your medical team can perform treatments to relax your vocal cords and ease your symptoms. As your vocal cords slowly relax and open, you may hear a high-pitched sound (stridor). The efficacy of lidocaine to either prevent or control extubation laryngospasm has been studied since the late 1970s.62Some articles have confirmed the efficacy of lidocaine for preventing postextubation laryngospasm, whereas others have found the opposite results to be true.16,63,,65A recent, well-conducted, randomized placebo-controlled trial in children undergoing cleft palate surgery demonstrated the effectiveness of IV lidocaine (1.5 mg/kg administered 2 min after tracheal extubation) in reducing laryngospasm and coughing (by 29.9% and 18.92%, respectively).64However, these favorable results were not confirmed in other studies.5,65The role of lidocaine (IV or topical) in preventing laryngospasm is still controversial.
