It persists for a longer period in the context of respiratory syncytial virus infection, hypoxia, and anemia.21, The diagnosis of laryngospasm depends on the clinical judgment of the anesthesiologist. It should be suspected whenever airway obstruction occurs, particularly in the absence of an obvious supraglottic cause. and bronchomotor reflexes, indicating that not only skeletal but also smooth muscles are involved in upper airway reflexes.19.

If these medications help, please consult your doctor before taking them long term. If you have recurring laryngospasms, schedule an appointment with a healthcare provider who specializes in laryngology (a subspecialty within the ear, nose and throat [ENT] department). Minimally invasive anti-reflux procedures, Advertising and sponsorship opportunities. Upper airway disorders. 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. Laryngospasms are rare and typically last for fewer than 60 seconds. Laryngospasm was treated by 50 mg propofol and manual positive pressure mask ventilation with 100% inspired oxygen. 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. If laryngospasms are due to anxiety, then anti-anxiety meds can help ease your spasms. Hobaika AB, Lorentz MN. 2021; doi: 10.1016/j.jvoice.2020.01.004. anaesthesia: laryngospasm. 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. 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). They can determine the cause of your laryngospasms and recommend an appropriate treatment plan. Even though laryngospasm isnt usually serious or life-threatening, the experience can be terrifying. PubMed PMID: 19669024. It is frequently observed in fetuses and newborns, whereas later on, laryngeal closure reflex and cough become predominant.21This developmental pattern may be implicated in sudden infant death. Laryngospasm Administer 100% oxygen via nasal mask Suction the oropharynx, hypopharynx, and nasopharynx with a tonsil suction tip Suction/remove all blood, saliva, and foreign material from the oral cavity Pack the surgical site to prevent bleeding into the hypopharynx Draw the tongue and/or mandible forward Adapted from Hampson-Evans D, Morgan P, Farrar M: Pediatric laryngospasm.

Alterations of upper airway reflexes may occur in several conditions. 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.

Understanding the mechanics of laryngospasm is crucial for proper treatment. If positive-pressure ventilation is to be performed, then moderate intermittent pressure should be applied. Risk Factors Associated with Perioperative Laryngospasm, Young age is one of the most important risk factors. can occur spontaneously, most commonly associated with extubation or ENT procedures CAUSES Local extubation especially children with URTI symptoms He is retaining oxygen saturations > 94 percent. Acta Anaesthesiol Scand 1999; 43:10813, Visvanathan T, Kluger MT, Webb RK, Westhorpe RN: Crisis management during anaesthesia: Laryngospasm. These are usually rare events and recurrence is uncommon, but if it happens, try to relax. The afferent nerve involved in laryngeal closure reflex is the superior laryngeal nerve. Because laryngospasm is a potential life-threatening postoperative event, the PACU nurse border: none; , partial or complete) and of the bradycardia as well as the existence of contraindication to succinylcholine. This rare phenomenon is often a symptom of an underlying condition. In the study by von Ungern-Sternberg et al. (https://pubmed.ncbi.nlm.nih.gov/34817079/), Visitation, mask requirements and COVID-19 information, chronic obstructive pulmonary disease (COPD). As your vocal cords slowly relax and open, you may hear a high-pitched sound (stridor). The final decision depends on the severity of the laryngospasm (i.e. 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. This topic is beyond the scope of this article but was recently described elsewhere.37Eighty percent of negative pressure pulmonary edema cases occur within min after relief of the upper airway obstruction, but delayed onset is possible with cases reported up to 46 h later. In the recent analysis of 189 reports of laryngospasm to the Australian Incident Monitoring Study, one in three patients suffered significant physiological disturbance. Sufficient depth of anesthesia must be achieved before direct airway stimulation is initiated (oropharyngeal airway insertion). The patient is unconscious and initially breathing easily with an oral airway in place. For example, you might be able to exhale and cough, but have difficulty breathing in. Breathe in slowly through your nose. 3, 5, 7 In both partial and complete laryngospasm, signs of varying degrees of airway obstruction, such as suprasternal retraction, supraclavicular retractions, tracheal tug, A recent retrospective study has assessed the incidence of laryngospasm in a large population and characterized the interventions used to treat these episodes.8The results have shown that treatment followed a basic algorithm including CPAP, deepening of anesthesia, muscle relaxation, and tracheal intubation. Example Plan for a neonate! Causes: hypocalcemia, painful stimuli . Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers. 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). It is not the same as choking. Anesthesia was induced by a resident under the direct supervision of a senior anesthesiologist with inhaled sevoflurane in a 50/50% (5 l/min) mixture of oxygen and nitrous oxide. Pediatr Emerg Care 1990; 6:1089, Woolf RL, Crawford MW, Choo SM: Dose-response of rocuronium bromide in children anesthetized with propofol: A comparison with succinylcholine. 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. Avoid breathing in through your nose. Laryngospasm is one of the many critical situations that any anesthesiologist should be able to manage efficiently. 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. font-weight: normal; Fig. Anesthesiology 2012; 116:458471 doi: https://doi.org/10.1097/ALN.0b013e318242aae9. Insufficient depth of anesthesia is one of the major causes of laryngospasm. Two min after loss of eyelash reflex, a first episode of airway obstruction with inspiratory stridor and suprasternal retraction was successfully managed by jaw thrust and manual positive pressure ventilation. A competence-based training that includes a structured curriculum and regular workplace-based assessment may help mitigate the effects of caseload reduction. Br J Anaesth 1998; 81:6925, Krodel DJ, Bittner EA, Abdulnour R, Brown R, Eikermann M: Case scenario: Acute postoperative negative pressure pulmonary edema. , gastric acid).24They (mechanical and chemical stimuli) are favored by local inflammation with subsequent alteration of pharyngolaryngeal sensation (URI, gastroesophageal reflux disease, neurologic disorders)20,2526; and factors influencing the central regulation system of upper airway reflexes, such as age.2021, After stimulation of the superior laryngeal nerve, apnea may result from several mechanisms: prolonged laryngeal closure reflex-related laryngeal obstruction (see the previously mentioned risk factors for increased laryngeal closure reflex); decreased swallowing reflex with accumulation of secretions in contact with the larynx vestibule and subsequent laryngeal closure reflex;21,27and centrally controlled apneic reflex possibly related to the diving reflex observed in aquatic mammals and aimed at preventing fluid aspiration in the lower airway. A detailed history should be taken to identify the risk factors. In reports addressing respiratory adverse events, including laryngospasm, the overall incidence of perioperative respiratory events as well as the incidence of laryngospasm was higher in 01-yr-old infants in comparison with older children.2,5,,7The risk of perioperative respiratory adverse event was quoted as decreasing by 8% for each increasing year of age.2A recent large cohort study confirmed this inverse relationship between age and risk of perioperative respiratory adverse events.5This study showed that the relative risk for perioperative respiratory adverse events, particularly laryngospasm, decreased by 11% for each yearly increase in age.5. Because these symptoms can be frightening, it is good to have a clear medical plan for prevention and treatment if you have any of these symptoms.

Laryngospasm may be preceded by a high-pitched inspiratory stridor some describe a characteristic crowing noise followed by complete airway obstruction. Some advocate delivery of jaw thrust and CPAP as the first airway opening maneuvers to improve breathing patterns in children with airway obstruction.42For others, both chin lift and jaw thrust maneuvers combined with CPAP improve the view of the glottic opening and decrease stridor in anesthetized, spontaneously breathing children.41It is likely that if the jaw thrust maneuver is properly applied, i.e. 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.

Management of refractory laryngospasm. This is because your vocal cords are contracted and closed tight during a laryngospasm. 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.

Among all upper airway reflexes, it is the most resistant to deepening anesthesia, whereas the coughing reflex is the most sensitive. We strongly encourage future studies assessing the effect of training and simulation on the management of laryngospasm in children at various levels of outcomes. The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. 2. Symptoms can be mild or severe. 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. In the study by von Ungern-Sternberg et al. 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. 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. Definition. 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. Anesthesia was then maintained by facemask with 2.0% expired sevoflurane in a mixture of oxygen and nitrous oxide 50/50%. During high-fidelity simulation, technical and nontechnical skills can then be integrated and practiced.

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. Laryngospasm. Some people may experience recurring (returning) laryngospasms. Learning breathing techniques can help you remain calm during an episode. The authors thank Frances O'Donovan, M.D., F.F.A.R.C.S.I. Target Audience: These risk factors can be 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. 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.

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). However, children younger than 3 yr may develop 510 URI episodes per year. None of the children in the chest compression group developed gastric distension (86.5% in the standard group). Common triggers of reflex laryngeal response during anesthesia are secretions, blood, insertion of an oropharyngeal airway suction catheter, and laryngoscopy. 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.

A "can't ventilate, can't intubate" scenario may be prolonged when rocuronium is administered. OVERVIEW Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers. Here are a couple of techniques to try during an attack: Because laryngospasm happens suddenly without warning, theres really no way to prevent it. However, the acquisition and the mastering of these skills during specialty training and their maintenance during continuing medical education represent a formidable challenge. } Review.

The purpose of this case scenario is to highlight keypoints essential for the prevention, diagnosis, and treatmentof laryngospasm occurring during anesthesia. 1. health information, we will treat all of that information as protected health 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. The cause of vocal cord spasms is often unknown, and it is usually in response to a trigger such as anxiety or acid reflux. Broaddus VC, et al. He is also a Clinical Adjunct Associate Professor at Monash University. In addition, a video of a simulated layngospasm scenario is available (See video, Supplemental Digital Content 1, http://links.lww.com/ALN/A807, which demonstrates the management of a simulated laryngospasm in a 10-month-old boy). The apneic reflex varies as a function of age. Designing an effective simulation scenario requires careful planning and can be broken into several steps. To confirm the diagnosis, your healthcare provider may look at your vocal cords with a laryngeal endoscope.
