Acid reflux may cause a few drops of stomach acid backwash to touch the vocal cords, setting off the spasm. Therefore, giving IV atropine before IV injection of suxamethonium to treat laryngospasm is mandatory.66. Anesthesia was then maintained by facemask with 2.0% expired sevoflurane in a mixture of oxygen and nitrous oxide 50/50%. Anaesthesia 2002; 57:1036, Chung DC, Rowbottom SJ: A very small dose of suxamethonium relieves laryngospasm. If IV access cannot be established in emergency, succinylcholine may be given by an alternative route.5354Intramuscular succinylcholine has been recommended at doses ranging from 1.5 to 4 mg/kg.53The main drawback of intramuscular administration is the slow onset in comparison with the IV route.

Case Scenario: - American Society of Anesthesiologists Here are a couple of techniques to try during an attack: Because laryngospasm happens suddenly without warning, theres really no way to prevent it. Thereafter, surgery was quickly completed, while tracheal extubation and postoperative recovery were uneventful. However, if youve experienced laryngospasms in the past, your healthcare provider can determine whats causing them and find ways to reduce your risk.

Despite a jaw thrust maneuver, positive pressure ventilation with 100% O2, and administration of two bolus doses (5 mg) of IV propofol (0.6 mg/kg), the obstruction was not relieved and SpO2decreased to 52%. Journal of Voice. The afferent nerves include the trigeminal nerve for the nasopharynx, the glossopharyngeal nerve for the oropharynx and hypopharynx, the superior and recurrent laryngeal nerves, and both branches of the vagus nerve, for the larynx and trachea. It is a primitive protective airway reflex that exists to . Relative Risk (95% CI) of Laryngospasm in Children According to the Presence of Cold Symptoms, Household exposure to tobacco smoke was shown to increase the incidence of laryngospasm from 0.9% to 9.4% in children scheduled for otolaryngology and urologic surgery.12This strong association between passive exposure to tobacco smoke and airway complications in children was also observed in another large study.13. Target Audience: American Academy of Allergy, Asthma and Immunology. Laryngospasm is usually defined as partial or complete airway obstruction associated with increasing abdominal and chest wall efforts to breathe against a closed glottis. The onset of a vocal cord spasm is sudden, and just as suddenly, it goes away, usually after . 5 Many high-acuity medical conditions can induce these. You might experience multiple laryngospasms in a brief time but in most cases, each episode ends after about a minute. Assist the patient's inspiratory effort with posi-tive-pressure ventilation with 100% oxygen. Taking an antacid or acid inhibitor for a few weeks may help diagnose the problem by the process of elimination. It may be difficult for a nonspecialist pediatric anesthesiologist to adequately manage an inhalational induction, because of the possibility to fail to manage the airway properly or the inability to recognize and treat early a stridor/laryngospasm. Laryngospasms that are caused by other conditions like asthma, stress or hypersensitivity arent usually dangerous or life-threatening. There are data supporting the efficacy of structured courses that integrate airway trainers and high fidelity simulation for airway management training.7677Recent evidence also supports the transfer of technical and nontechnical skills acquired during simulation to the clinical setting.78We therefore strongly encourage the integration of simulation-based training for pediatric airway management, including for the management of laryngospasm. For example, you might be able to exhale and cough, but have difficulty breathing in. It is mandatory to procure user consent prior to running these cookies on your website.

This function involves several upper airway reflexes: the laryngeal closure reflex, which consists of vocal fold adduction; apnea; swallowing; and coughing.19To efficiently protect the airway, laryngeal closure reflex must be coordinated with swallowing. Although third-level studies may prove very difficult or subject to bias, first- and second-level studies are feasible but have yet to be performed for laryngospasm and pediatric airway training. Last reviewed by a Cleveland Clinic medical professional on 02/11/2022. Although described in the conscious state and associated with silent reflux, laryngospasm is a problematic reflex which occurs often under general anaesthesia. #mc_embed_signup { It normally passes quickly and is not dangerous, but some . Understanding the mechanics of laryngospasm is crucial for proper treatment. More children who developed laryngospasm were successfully treated with chest compression (73.9%) compared with those managed with the standard method (38.4%; P< 0.001). Indian J Anaesth 2010; 54:1326, Behzadi M, Hajimohamadi F, Alagha AE, Abouzari M, Rashidi A: Endotracheal tube cuff lidocaine is not superior to intravenous lidocaine in short pediatric surgeries. They are most likely located in the medullary neuronal network rather than in the brainstem.2223The higher center seems to regulate upper airway reflexes. Like any other crisis, such management requires the application of appropriate knowledge, technical skills, and teamwork skills (or nontechnical skills). Click here for an email preview.

IV line insertion should also be delayed until deep anesthesia (regular ventilation with large tidal volume, eyeballs fixed with pupils centered in myosis or moderately dilated) is achieved. Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers. The onset of a vocal cord spasm is sudden, and just as suddenly, it goes away, usually after a few minutes.
