Paediatr Anaesth 2008; 18:297302, Cohen MM, Cameron CB: Should you cancel the operation when a child has an upper respiratory tract infection? Postoperative negative pressure pulmonary edema typically occurs in response to an upper airway obstruction, where patients can generate high negative intrathoracic pressures, leading to a postrelease pulmonary edema. Paroxysmal Laryngospasm: A Rare Condition That Respiratory Physicians Must Distinguish from Other Diseases with a Chief Complaint of Dyspnea. Nasal foreign body, ketamine and laryngospasm, Clinical Adjunct Associate Professor at Monash University, Australia and New Zealand Clinician Educator Network, Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License. demonstrated that in children age 26 yr, laryngeal and respiratory reflex responses differed between sevoflurane and propofol at similar depths of anesthesia, with apnea and laryngospasm being less severe with propofol.33If tracheal intubation is planned, the use of muscle relaxants prevents the risk of laryngospasm.2In contrast, topical anesthesia is probably not effective and the incidence of laryngospasm is even higher when vocal cords are sprayed with aerosolized lidocaine.5, Laryngospasm is commonly caused by systemic painful stimulation if the anesthesia is too light during maintenance. https://www.aaaai.org/conditions-treatments/related-conditions/vocal-cord-dysfunction. Paediatr Anaesth 2003; 13:437, Schreiner MS, O'Hara I, Markakis DA, Politis GD: Do children who experience laryngospasm have an increased risk of upper respiratory tract infection? The patient is unconscious and initially breathing easily with an oral airway in place. } Adults may be less prone to development of laryngospasm.

Laryngospasm (luh-RING-o-spaz-um) is a condition in which your vocal cords suddenly spasm (involuntarily contract or seize). It is bounded anteriorly by the ascending ramus of the mandible adjacent to the condyle, posteriorly by the mastoid process of the temporal bone, and cephalad by the base of the skull.. border: none; The purpose of this case scenario is to highlight keypoints essential for the prevention, diagnosis, and treatmentof laryngospasm occurring during anesthesia. display: inline; Several studies suggest that deep extubation reduces this incidence, whereas others observed no difference.5,3435In one study, tracheal intubation with deep extubation was associated with increased respiratory adverse events rate (odds ratio = 2.39) compared with LMA removal at a deep level of anesthesia, whereas use of a facemask alone decreased respiratory adverse events (odds ratio = 0.15).35The difference between LMA and ETT was less evident when awake extubation was used (odds ratio = 0.65 and 1.26, respectively). , otolaryngology surgery).2,5,,7Many factors may increase the risk of laryngospasm. tracheal tug, indrawing), vomiting or desaturation. Whereas epithelial damage heals in 12 weeks, virus-induced sensitization of bronchial autonomic efferent pathways can last for up to 68 weeks. Taking an antacid or acid inhibitor for a few weeks may help diagnose the problem by the process of elimination. Jun 2005;14(3):e3. Laryngospasm is a rare but frightening experience. However, the acquisition and the mastering of these skills during specialty training and their maintenance during continuing medical education represent a formidable challenge. These interventions include removal of the irritant stimulus,8,38chin lift, jaw thrust,39continuous positive airway pressure (CPAP), and positive pressure ventilation with a facemask and 100% O2.3,40,,43These maneuvers are popular because they have been shown to improve the patency of the upper airway in case of airway obstruction.42,4445Less commonly used airway maneuvers, such as pressure in the laryngospasm notch4,44and digital elevation of the tongue46also have been proposed as rapid and effective methods.8Overall conflicting results have been obtained regarding the best maneuver to relieve airway obstruction in children with laryngospasm. On the other hand, attempts to provide positive-pressure ventilation with a facemask may distend the stomach, increasing the risk of gastric regurgitation.

Muscles involved: lateral cricoarytenoid, thyroarytenoids (both from recurrent laryngeal), crycrothyroid (from external branch of superior laryngeal). have demonstrated an increased risk for laryngospasm only when cold symptoms are present the day of surgery or less than 2 weeks before (table 2).5Therefore, for children who present for elective procedures with a temperature higher than 38C, mucopurulent airway secretions, or lower respiratory tract signs such as wheezing and moist cough, surgery is usually postponed. Pediatr Pulmonol 2010; 45:4949, Afshan G, Chohan U, Qamar-Ul-Hoda M, Kamal RS: Is there a role of a small dose of propofol in the treatment of laryngeal spasm? If laryngospasms are due to anxiety, then anti-anxiety meds can help ease your spasms. Used with permission of John Wiley and Sons. In fact, when the inspiratory stridulous noise was noted again, the patient was receiving 2% end-tidal sevoflurane and 50% N2O, representing barely 1 minimum alveolar concentration in an infant. The next line of therapy would be to administer a low dose of succinylcholine (10Y20 mg) to relax the . In most cases, a laryngospasm lasts for up to one minute, but it may feel much longer. Br J Anaesth 2001; 86:21722, Mark LC: Treatment of laryngospasm by digital elevation of tongue (letter). Portuguese. Laryngospasm in amyotrophic lateral sclerosis. , partial or complete) and of the bradycardia as well as the existence of contraindication to succinylcholine.

Therefore, giving IV atropine before IV injection of suxamethonium to treat laryngospasm is mandatory.66. Vocal cord dysfunction. PubMed PMID: Orliaguet GA, Gall O, Savoldelli GL, Couloigner V. Case scenario: perianesthetic management of laryngospasm in children. . Can J Anaesth 2010; 57:74550, Sanikop C, Bhat S: Efficacy of intravenous lidocaine in prevention of post extubation laryngospasm in children undergoing cleft palate surgeries. Although the efficacy of subhypnotic doses of propofol has been suggested in children, there is a possibility that these doses are inadequate in infants, especially in those younger than 1 yr. 1. 2). A "can't ventilate, can't intubate" scenario may be prolonged when rocuronium is administered. In a more recent series, the overall incidence of laryngospasm was lower8but the predominance of such incidents at a young age was still clear: 50 to 68% of cases occurred in children younger than 5 yr. Laryngospasm may not be obvious it may present as increased work of breathing (e.g. Laryngospasms can be frightening, whether youve experienced them before or not. [Laryngospasm]. However, children younger than 3 yr may develop 510 URI episodes per year. 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. Khanna S (expert opinion). background: #fff; PEEP! Most of the time, your healthcare provider can diagnose laryngospasm by reviewing your symptoms and medical history. There is controversy in the literature regarding the use of inhalational or IV induction agents and associated risk of laryngospasm. Paediatr Anaesth 2002; 12:6258, Batra YK, Ivanova M, Ali SS, Shamsah M, Al Qattan AR, Belani KG: The efficacy of a subhypnotic dose of propofol in preventing laryngospasm following tonsillectomy and adenoidectomy in children. Larson CP Jr. Laryngospasmthe best treatment. Upper airway disorders. If you or someone youre with is having a laryngospasm, you should: In addition to the techniques outlined above, there are breathing exercises that can help you through a laryngospasm. As a result, your airway becomes temporarily blocked, making it difficult to breathe or speak. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7361892/). A simulation scenario is an artificial representation of a real-world event to achieve educational goals through experiential learning. The highest incidence of laryngospasm is found in procedures involving surgery and manipulations of the pharynx and larynx.2,5,,7The incidence of laryngospasm, after tracheal extubation, has already been reported to exceed 20% and be as high as 26.5% in pediatric patients who have undergone tonsillectomy.14,,17Urgent procedures also carry a higher risk of laryngospasm than elective procedures. A new episode of laryngospasm was immediately suspected. In contrast, results from studies in children with recent URIs have shown that LMA was associated with an increased occurrence of laryngospasm.28,32In a recent, large, prospective study, the incidence of laryngospasm was increased after direct stimulation of the upper airway by both LMA and ETT in comparison with a facemask.5Therefore, LMA may be considered more stimulating than the facemask but certainly less than the ETT. These preliminary results are interesting and need to be confirmed by further studies.

Here are some important features to keep in mind: Complete blockage may present as just apnea; Can be preceded by high-pitched inspiratory stridor, followed by complete airway obstruction The treatment includes opening and clearing the oropharynx, applying CPAP with 100% oxygen, followed by deepening of anaesthesia usually with an i.v . 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. c. Treatment of laryngospasm is aimed at supporting ventilation. Acta Anaesthesiol Scand 1999; 43:10813, Visvanathan T, Kluger MT, Webb RK, Westhorpe RN: Crisis management during anaesthesia: Laryngospasm. Anesthesiology. Nov. 7, 2021.

The diagnosis of laryngospasm is made and treated, only to reveal persistent hypoxemia and negative-pressure pulmonary edema (NPPE). 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. Sufficient depth of anesthesia must be achieved before direct airway stimulation is initiated (oropharyngeal airway insertion). During high-fidelity simulation, technical and nontechnical skills can then be integrated and practiced. 5 of 7 This document is not intended to provide a comprehensiv e discussion of each drug.

If this happens to you, talk to your healthcare provider. stroke, hypoxic encephalopathy), Attempt to break the laryngospasm by applying painful inward and anterior pressure at , If hypoxia supervenes consider administering, Laryngospasm is usually brief and may be followed by a. 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%. The . information submitted for this request. They can perform an examination and find out if there are ways to prevent laryngospasm from happening in the future. The authors also thank Frank Schneider (Editing Coordinator, Division of Communication and Marketing of the Geneva University Hospitals, Geneva University Hospitals) and Justine Giliberto (Editing, Division of Communication and Marketing of the Geneva University Hospitals) for editing the video material. Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers. Laryngospasm is a frightening condition that happens when your vocal cords suddenly seize up, making breathing more difficult. ANESTHESIOLOGY 2005; 103:11428, Patel RI, Hannallah RS, Norden J, Casey WF, Verghese ST: Emergence airway complications in children: A comparison of tracheal extubation in awake and deeply anesthetized patients.

Anesth Analg 1978; 57:5067, Schebesta K, Gloglu E, Chiari A, Mayer N, Kimberger O: Topical lidocaine reduces the risk of perioperative airway complications in children with upper respiratory tract infections. While laryngospasms affect your vocal cords (two bands of tissue housed inside of your larynx), bronchospasms affect your bronchi (the airways that connect your windpipe to your lungs). Laryngospasm is the sustained closure of the vocal cords resulting in the partial or complete loss of the patient's airway. We do not endorse non-Cleveland Clinic products or services. A 0.2-mg IV bolus dose of atropine was injected and IV succinylcholine was given at a dose of 16 mg, followed by tracheal intubation. SimBaby is a tetherless simulator designed to help healthcare providers effectively recognize and respond to critically ill pediatric patients. It normally passes quickly and is not dangerous, but some . Among all upper airway reflexes, it is the most resistant to deepening anesthesia, whereas the coughing reflex is the most sensitive. ,5emergent procedures had a moderately higher risk than elective procedures for perioperative respiratory adverse events, including laryngospasm (17%vs. Table 2. Simulation-based Training Scenario Laryngospasm during Induction of General Anesthesia in a 10-month-old Boy. (Staff Anesthesiologist, Department of Anesthesiology, Pharmacology and Intensive Care, Geneva University Hospitals, Geneva, Switzerland), and Jos-Manuel Garcia (Technical Coordinator, Department of Anesthesiology, Pharmacology and Intensive Care, Geneva University Hospitals) for their contribution in the video of the simulated scenario. Mayo Clinic offers appointments in Arizona, Florida and Minnesota and at Mayo Clinic Health System locations. However, some authors have observed that emergence from anesthesia tends to become the most critical period, possibly in relation to changes in practice including the use of laryngeal mask airway (LMA) and/or of propofol and newer inhalational agents.8, Laryngospasm can result in life-threatening complications, including severe hypoxia, bradycardia, negative pressure pulmonary edema, and cardiac arrest. Avoid breathing in through your nose. A characteristic crowing noise may be heard in partial laryngospasm but will be absent in complete laryn-gospasm. Some people may experience recurring (returning) laryngospasms. He is on the Board of Directors for theIntensive Care Foundationand is a First Part Examiner for theCollege of Intensive Care Medicine. Rev Bras Anestesiol. Their motoneurons are located in the brainstem nucleus ambiguous and the adjacent nucleus retroambigualis. If complete laryngospasm cannot be rapidly relieved, IV agents should be quickly considered. So when in doubt, meticulous observation with aggressive preparation may be reasonable.

Laryngospasms that are caused by other conditions like asthma, stress or hypersensitivity arent usually dangerous or life-threatening. } 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. During observation, she exhibits a sudden increase in respiratory effort and noise with ventilation. You also have the option to opt-out of these cookies. It should be suspected whenever airway obstruction occurs, particularly in the absence of an obvious supraglottic cause. None of the children in the chest compression group developed gastric distension (86.5% in the standard group).

These cookies do not store any personal information. These are the reasons why inhalational induction conducted by nonspecialized anesthetists remains associated with an increased risk of laryngospasm.2,5,18In children with hyperactive airways, there are now several arguments in favor of IV induction with propofol versus inhalational induction. Perianesthetic Management of Hypertrophic Cardiomyopathy, Copyright 2023 American Society of Anesthesiologists. To avoid significant morbidity and mortality, the use of a structured algorithm has been proposed.8,70One study suggests that if correctly applied, a combined core algorithm recommended for the diagnosis and management of laryngospasm would have led to earlier recognition and/or better management in 16% of the cases.70These results should encourage physicians to implement their own structured algorithm for the diagnosis and management of laryngospasm in children in their institutions. The afferent nerve involved in laryngeal closure reflex is the superior laryngeal nerve. You might experience multiple laryngospasms in a brief time but in most cases, each episode ends after about a minute.
