GillesA. Orliaguet, Olivier Gall, GeorgesL. Savoldelli, Vincent Couloigner, Bruno Riou; Case Scenario: Perianesthetic Management of Laryngospasm in Children. #mc_embed_signup { Laryngospasm can happen suddenly and without warning, lasting up to one minute. Both conditions result in sudden, frightening spasms and both conditions can temporarily affect your ability to breathe and speak. Therefore, giving IV atropine before IV injection of suxamethonium to treat laryngospasm is mandatory.66. Laryngospasm is a sudden spasm of the vocal cords. The patient will then develop worsened hypotension, requiring the start of an epinephrine infusion. 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 procedure was expected to be very short, and general anesthesia with inhalational induction and maintenance, but without tracheal intubation, was planned. 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.

Whether or not this is relevant to perioperative risk of laryngospasm has been questioned many times in the literature.9,11Von Ungern-Sternberg et al. ANESTHESIOLOGY 1956; 17:56977, Crawford MW, Rohan D, Macgowan CK, Yoo SJ, Macpherson BA: Effect of propofol anesthesia and continuous positive airway pressure on upper airway size and configuration in infants. They are most likely located in the medullary neuronal network rather than in the brainstem.2223The higher center seems to regulate upper airway reflexes. However, if youve experienced laryngospasms in the past, your healthcare provider can determine whats causing them and find ways to reduce your risk. Any stimulation in the area supplied by the superior laryngeal nerve, during a light plane of anesthesia, may produce laryngospasm. Difficulty breathing ( dyspnea) Fatigue and exhaustion are other less-common and more subtle symptoms that may be associated with bronchospasm.

Even though laryngospasm isnt usually serious or life-threatening, the experience can be terrifying. Laryngospasms are rare and typically last for fewer than 60 seconds. Laryngospasm is a frightening condition that happens when your vocal cords suddenly seize up, making breathing more difficult. The . Sometimes, laryngospasm happens for seemingly no reason. The team must initiate usual anaphylaxis treatment including salbutamol for bronchospasm. Laryngospasms that are caused by other conditions like asthma, stress or hypersensitivity arent usually dangerous or life-threatening. ANESTHESIOLOGY 2001; 95:103940, Liu LM, DeCook TH, Goudsouzian NG, Ryan JF, Liu PL: Dose response to intramuscular succinylcholine in children.

Laryngospasm is usually defined as partial or complete airway obstruction associated with increasing abdominal and chest wall efforts to breathe against a closed glottis.3,5,7In both partial and complete laryngospasm, signs of varying degrees of airway obstruction, such as suprasternal retraction, supraclavicular retractions, tracheal tug, paradoxical chest, and abdominal movements may be seen.3In addition, inspiratory stridor may be heard in partial laryngospasm but is absent in complete spasm. Review. 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.

PubMed PMID: 19669024. 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. Anesthesiology. 2. Acid reflux may cause a few drops of stomach acid backwash to touch the vocal cords, setting off the spasm. Taking an antacid or acid inhibitor for a few weeks may help diagnose the problem by the process of elimination. 9500 Euclid Avenue, Cleveland, Ohio 44195 |, Important Updates + Notice of Vendor Data Event. Vocal cord dysfunction. PubMed PMID: Salem MR, Crystal GJ, Nimmagadda U. Last reviewed by a Cleveland Clinic medical professional on 02/11/2022. Thus, the potential window for safe administration of general anesthesia is frequently very short. As your vocal cords slowly relax and open, you may hear a high-pitched sound (stridor). border: none; Other pharmacologic agents have been proposed for the prevention and/or treatment of laryngospasm, including magnesium,17doxapram,67diazepam,68and nitroglycerine.69However, because of the small number of patients included in these series no firm conclusions can be drawn. The diagnosis of laryngospasm is made and treated, only to reveal persistent hypoxemia and negative-pressure pulmonary edema (NPPE).

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). display: inline; These results are in accordance with a study showing that subhypnotic doses of propofol (0.5 mg/kg) decreased the likelihood of laryngospasm upon tracheal extubation in children undergoing tonsillectomy with or without adenoidectomy.50Lower doses of propofol (0.25 mg/kg) have also been used successfully to relax the larynx in a small series.51It should be noted that few data are available regarding the use of propofol to treat laryngospasm in younger age groups (younger than 3 yr). He is one of the founders of theFOAMmovement (Free Open-Access Medical education) and is co-creator oflitfl.com,theRAGE podcast, theResuscitologycourse, and theSMACCconference. 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. Anaesthesia 1998; 53:91720, Ko C, Kocaman F, Aygen E, Ozdem C, Ceki A: The use of preoperative lidocaine to prevent stridor and laryngospasm after tonsillectomy and adenoidectomy. Assist the patient's inspiratory effort with posi-tive-pressure ventilation with 100% oxygen. A detailed history should be taken to identify the risk factors. 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.

Laryngospasm usually isnt life-threatening, but it can be a terrifying experience. Below a cardiac temperature of 28C, the heart may suddenly and spontaneously arrest. (Staff Anesthesiologist, Department of Anaesthesia, Children's University Hospital, Dublin, Ireland), for kindly reviewing the manuscript; Hlne Mathey-Doret, M.D. If the cause is unclear, your doctor may refer you to an ear, nose and throat specialist (otolaryngologist) to look at your vocal cords with a mirror or small fiberscope to be sure there is no other abnormality. A 10-month-old boy (8.5 kg body weight) was taken to the operating room (at 11:00 PM), without premedication, for emergency surgery of an abscess of the second fingertip on the right hand. Common triggers of reflex laryngeal response during anesthesia are secretions, blood, insertion of an oropharyngeal airway suction catheter, and laryngoscopy.

Laryngoscope 2006; 116:1397403, Nishino T, Hasegawa R, Ide T, Isono S: Hypercapnia enhances the development of coughing during continuous infusion of water into the pharynx. Rarely, negative pressure pulmonary edema may occur and requires specific treatment.37The high chest wall to lung compliance ratio observed during infancy, which disappears by the second year of life because of increased chest wall stiffness, may explain why negative pressure pulmonary edema is less frequent in infants than in older children or adults. However, children younger than 3 yr may develop 510 URI episodes per year. Both reflexes are sometimes considered as a single phylogenetic reflex.20The neuronal pathways underlying upper airway reflexes include an afferent pathway, a common central integration network, and an efferent pathway.19. Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers.

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. For laryngeal closure reflex, several types of receptors can be distinguished, according to their specific sensitivities to cold, pressure, laryngeal motion, and chemical agents.19,21The chemoreceptors are sensitive to fluids with low chloride or high potassium concentrations, as well as to strong acidic or alkaline solutions.19,21.

If you have any of the conditions listed above, talk to your healthcare provider about ways to reduce your risk for laryngospasms. Identifying patients at increased risk for laryngospasm and taking recommended precautions are the most important measures to prevent laryngospasm (fig. Epidemiology of Laryngospasm in Pediatric Patients Children are more prone to laryngospasm than adults, with laryngospasm being reported more commonly in children 1,000).2,5-7 In fact, the incidence of laryngospasm has been gery (i.e., otolaryngology surgery).2,5-7 Many factors may increase the risk of laryngospasm.

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. This content does not have an Arabic version. Accessed Nov. 5, 2021. In children with URI, the use of an endotracheal tube (ETT) may increase by 11-fold the risk of respiratory adverse events, in comparison with a facemask.11Less invasive airway management could be beneficial in children with airway hyperactivity. His one great achievement is being the father of three amazing children. PubMed PMID: Orliaguet GA, Gall O, Savoldelli GL, Couloigner V.

Sufficient depth of anesthesia must be achieved before direct airway stimulation is initiated (oropharyngeal airway insertion). Thereafter, surgery was quickly completed, while tracheal extubation and postoperative recovery were uneventful. 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. He had been fasting for the past 6 h. Preoperative evaluation was normal (systemic blood pressure 85/50 mmHg, heart rate 115 beats/min, pulse oximetry [SpO2] 99% on room air). As a result, your airway becomes temporarily blocked, making it difficult to breathe or speak. Complete airway obstruction is characterized by: Where is the laryngospasm notch?

Rutt AL, et al. After finishing his medical degree at the University of Auckland, he continued post-graduate training in New Zealand as well as Australias Northern Territory, Perth and Melbourne. Laryngospasm (luh-RING-o-spaz-um) is a condition in which your vocal cords suddenly spasm (involuntarily contract or seize). Even though you may feel like you cant breathe, try to remember that the episode will pass. No chest wall movement with no breath sounds on auscultation, Inability to manually ventilate with bag-mask ventilation, ischemic end organ injury (e.g. 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. The question of whether using propofol or muscle relaxant first is a matter of timing. 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. For instance, coughing can be voluntarily inhibited. 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. 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.
