Orliaguet, Olivier Gall, GeorgesL. Savoldelli, Vincent Couloigner, Bruno Riou; Case Scenario: Perianesthetic Management of Laryngospasm in Children. Whereas epithelial damage heals in 12 weeks, virus-induced sensitization of bronchial autonomic efferent pathways can last for up to 68 weeks. Br J Anaesth 2001; 86:21722, Mark LC: Treatment of laryngospasm by digital elevation of tongue (letter). If you have any of the conditions listed above, talk to your healthcare provider about ways to reduce your risk for laryngospasms. You might experience multiple laryngospasms in a brief time but in most cases, each episode ends after about a minute. To reverse laryngospasm after surgery with anesthesia, your medical team can perform treatments to relax your vocal cords and ease your symptoms. According to Phil Larson: This notch is behind the lobule of the pinna of each ear. The team must initiate usual anaphylaxis treatment including salbutamol for bronchospasm. width: auto; Breathe in and out through the straw without pausing between the inhale and the exhale. Based on a work athttps://litfl.com. In addition, in complete laryngospasm, there is no air movement, no breath sounds, absence of movement of the reservoir bag, and flat capnogram.3Finally, late clinical signs occur if the obstruction is not relieved including oxygen desaturation, bradycardia, and cyanosis.3. Paediatr Anaesth 2002; 12:1405, Plaud B, Meretoja O, Hofmockel R, Raft J, Stoddart PA, van Kuijk JH, Hermens Y, Mirakhur RK: Reversal of rocuronium-induced neuromuscular blockade with sugammadex in pediatric and adult surgical patients. Anaesthesia 1982; 37:11124, Postextubation laryngospasm. PERIOPERATIVE laryngospasm is an anesthetic emergency that is still responsible for significant morbidity and mortality in pediatric patients.1It is a relatively frequent complication that occurs with varying frequency dependent on multiple factors.2,,5Once the diagnosis has been made, the main goals are identifying and removing the offending stimulus, applying airway maneuvers to open the airway, and administering anesthetic agents if the obstruction is not relieved. Laryngospasm (luh-RING-go-spaz-um) is a transient and reversible spasm of the vocal cords that temporarily makes it difficult to speak or breathe. From: Encyclopedia of . 1998 Nov;89(5):1293-4. 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. } (https://pubmed.ncbi.nlm.nih.gov/34817079/), Visitation, mask requirements and COVID-19 information, chronic obstructive pulmonary disease (COPD). Anesthesiology. A competence-based training that includes a structured curriculum and regular workplace-based assessment may help mitigate the effects of caseload reduction. Thereafter, surgery was quickly completed, while tracheal extubation and postoperative recovery were uneventful. can occur spontaneously, most commonly associated with extubation or ENT procedures CAUSES Local extubation especially children with URTI symptoms #mc-embedded-subscribe-form input[type=checkbox] { Some people may experience recurring (returning) laryngospasms. Common presenting signs and symptoms include tachypnea, tachycardia, diaphoresis, trembling, palpitations, shortness of breath and chest pain. He is on the Board of Directors for theIntensive Care Foundationand is a First Part Examiner for theCollege of Intensive Care Medicine. Singapore Med J 1998; 39:32830, Warner DO: Intramuscular succinylcholine and laryngospasm. Prospective studies supported the use of LMA over ETT in children with URI.3031However, these studies were underpowered to detect differences in laryngospasm. The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. ANESTHESIOLOGY 2009; 110:28494, Baraka A: Intravenous lidocaine controls extubation laryngospasm in children. Accessed Nov. 5, 2021. Policy. He is retaining oxygen saturations > 94 percent. Here are a couple of techniques to try during an attack: Because laryngospasm happens suddenly without warning, theres really no way to prevent it. Designing an effective simulation scenario requires careful planning and can be broken into several steps. #mc-embedded-subscribe-form .mc_fieldset { 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.

The . SimBaby is a tetherless simulator designed to help healthcare providers effectively recognize and respond to critically ill pediatric patients. Breathe in slowly through your nose. He is a co-founder of theAustralia and New Zealand Clinician Educator Network(ANZCEN) and is the Lead for theANZCEN Clinician Educator Incubatorprogramme. If complete laryngospasm cannot be rapidly relieved, IV agents should be quickly considered. 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. A laryngospasm is a muscle spasm in the vocal cords that can lead to problems with speaking and breathing. In the study by von Ungern-Sternberg et al. For children with URI, cancellation of elective procedures for a period of 46 weeks was traditionally the rule. During high-fidelity simulation, technical and nontechnical skills can then be integrated and practiced. Laryngospasm is one of the many critical situations that any anesthesiologist should be able to manage efficiently. scenario #2: the non-crashing epiglottitis patient. Paediatr Anaesth 2008; 18:3037, von Ungern-Sternberg BS, Boda K, Chambers NA, Rebmann C, Johnson C, Sly PD, Habre W: Risk assessment for respiratory complications in paediatric anaesthesia: A prospective cohort study. The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. Only sevoflurane or halothane should be used for inhalational induction. Therefore, the injection of IV succinylcholine was required to treat this persistent laryngospasm. Furthermore, the efficacy of propofol to break complete laryngospasm when bradycardia is present has been questioned.4In our case, two bolus doses of 5 mg IV propofol (each representing a dose of 0.6 mg/kg) were administered but did not relieve airway obstruction. 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.

Elsevier; 2022. https://www.clinicalkey.com. 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. Mayo Clinic is a nonprofit organization and proceeds from Web advertising help support our mission. Experimental evidences and anecdotal reports indicate that intraosseous and IV injection behave similarly, resulting in adequate intubating conditions within 45 s (1 mg/kg).57In children in whom succinylcholine is contraindicated, rocuronium administered at a dose of two to three times the ED95(0.9 to 1.2 mg/kg) may represent a reasonable substitute when rapid onset is needed.58,,60In addition, there is a possibility to quickly reverse the neuromuscular blockade induced by rocuronium using sugammadex if necessary.61. Even though you may feel like you cant breathe, try to remember that the episode will pass. In the study by von Ungern-Sternberg et al. You also have the option to opt-out of these cookies.

Get useful, helpful and relevant health + wellness information. 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. To provide you with the most relevant and helpful information, and understand which ANESTHESIOLOGY 1981; 55:599602, Walker RW, Sutton RS: Which port in a storm? More specifically, laryngeal closure reflex involves the laryngeal intrinsic muscles responsible for vocal folds adduction, i.e. It is not the same as choking. People with laryngospasm are unable to speak or breathe. ANESTHESIOLOGY 2001; 95:299306, Lakshmipathy N, Bokesch PM, Cowen DE, Lisman SR, Schmid CH: Environmental tobacco smoke: A risk factor for pediatric laryngospasm. But it can be a symptom of other conditions, including: Left untreated, laryngospasm caused by anesthesia can be fatal. During the exercise, the instructor can observe and measure the performance of the trainees and compare them with the standards of performance mentioned in the algorithms. It should be suspected whenever airway obstruction occurs, particularly in the absence of an obvious supraglottic cause. In case of sale of your personal information, you may opt out by using the link. Symptoms can be mild or severe. Risk Factors Associated with Perioperative Laryngospasm, Young age is one of the most important risk factors. The locations of involved nerve receptors vary as a function of the upper airway reflex: pharyngeal mucosa for the swallowing reflex, supraglottic larynx for laryngeal closure reflex,19larynx and trachea for cough, and any part of the upper airway (but mainly nose and larynx) for apnea. , otolaryngology surgery).2,5,,7Many factors may increase the risk of laryngospasm. The vocal cords are two fibrous bands inside the voice box (larynx) at the top of the windpipe (trachea).

OVERVIEW Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers. Review. Paediatr Anaesth 2007; 17:15461, Guglielminotti J, Constant I, Murat I: Evaluation of routine tracheal extubation in children: Inflating or suctioning technique? The cause of vocal cord spasms is often unknown, and it is usually in response to a trigger such as anxiety or acid reflux. ANESTHESIOLOGY 1996; 85:47580, Nishino T: Physiological and pathophysiological implications of upper airway reflexes in humans. Even though laryngospasms are scary when they happen, they usually dont cause serious problems. 2. Finally, third-level studies evaluate the effect of education on patient outcomes. ANESTHESIOLOGY 1997; 87:136872, Mazurek AJ, Rae B, Hann S, Kim JI, Castro B, Cot CJ: Rocuronium, Cheng CA, Aun CS, Gin T: Comparison of rocuronium and suxamethonium for rapid tracheal intubation in children. include protected health information. The first step of laryngospasm management is prevention. There is a need to fill this knowledge gap and to answer questions about what types of clinical education and what type of management algorithm result in better outcome. Effective management of laryngospasm in children requires appropriate diagnosis,4followed by prompt and aggressive management.8Many authors recommend applying airway manipulation first, beginning with removal of the irritant stimulus38and then administering pharmacologic agents if necessary.8. They can determine the cause of your laryngospasms and recommend an appropriate treatment plan. Laryngospasms that are caused by other conditions like asthma, stress or hypersensitivity arent usually dangerous or life-threatening.

Laryngospasm remains the leading cause of perioperative cardiac arrest from respiratory origin in children.1, The upper airway has several functions (swallowing, breathing, and phonation) but protection of the airway from any foreign material is the most essential. J Pediatr 1985; 106:6259, Nishino T, Isono S, Tanaka A, Ishikawa T: Laryngeal inputs in defensive airway reflexes in humans. ANESTHESIOLOGY 1963; 24:585, Al-Metwalli RR, Mowafi HA, Ismail SA: Gentle chest compression relieves extubation laryngospasm in children. Thus, the potential window for safe administration of general anesthesia is frequently very short. Exhale through pursed lips. border: none; Any stimulation in the area supplied by the superior laryngeal nerve, during a light plane of anesthesia, may produce laryngospasm. Anesth Analg 1985; 64:11936, Lee CK, Chien TJ, Hsu JC, Yang CY, Hsiao JM, Huang YR, Chang CL: The effect of acupuncture on the incidence of postextubation laryngospasm in children. (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. Although described in the conscious state and associated with silent reflux, laryngospasm is a problematic reflex which occurs often under general anaesthesia. Learning objectives should be based on recommended management algorithms and used as inputs and events embedded into one (or several) case scenario that form the basis for the simulated exercise. 5 Many high-acuity medical conditions can induce these. However, waiting until hypoxia opens the airway is not recommended, because a postobstruction pulmonary edema or even cardiac arrest may occur.43. Anaesthesia 2007; 62:7579, Tobias JD, Nichols DG: Intraosseous succinylcholine for orotracheal intubation. Airway simulators and high fidelity mannequins are important teaching tools.73Simple bench models, airway mannequins, and virtual reality simulators can be used to learn and practice basic and complex technical skills. He is an internationally recognised Clinician Educator with a passion for helping clinicians learn and for improving the clinical performance of individuals and collectives. . #mc_embed_signup { He has a known allergy to peanuts.

Accessed Nov. 5, 2021. Experimentally, Oberer et al. Mayo Clinic does not endorse any of the third party products and services advertised. There is a problem with This situation creates a risk of bronchopulmonary infection, chronic cough, and bronchospasm. For example, if laryngospasms are linked to GERD, then treating chronic acid reflux can also reduce your risk for laryngospasm. #mergeRow-gdpr { suggests that maintenance with sevoflurane was associated with a higher incidence of laryngospasm compared with propofol (relative risk 2.37, 95% CI 1.493.76; P< 0.0001).5In our case, the second episode of laryngospasm occurred while the patient was under light anesthesia. A computer-aided incidence study in 136,929 patients Acta Anaesthesiol Scand 1984; 28:56775, Burgoyne LL, Anghelescu DL: Intervention steps for treating laryngospasm in pediatric patients. As a result, your airway becomes temporarily blocked, making it difficult to breathe or speak. The onset of a vocal cord spasm is sudden, and just as suddenly, it goes away, usually after . padding-bottom: 0px; This usually occurs because of stimulation during a light plane of anaesthesia but may also occur because of blood, secretions, and foreign bodies (e.g.
