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). . Used with permission of John Wiley and Sons. For example, if laryngospasms are linked to GERD, then treating chronic acid reflux can also reduce your risk for laryngospasm. Treatment of laryngospasm. This paper discusses a case study where the patient had laryngospasm, it also looks at the pathophysiology, risk factors and management of . Advertising revenue supports our not-for-profit mission. margin-top: 20px; In most cases, a laryngospasm lasts for up to one minute, but it may feel much longer. During high-fidelity simulation, technical and nontechnical skills can then be integrated and practiced. Med Educ 2010; 44:5063, Savoldelli GL, Naik VN, Park J, Joo HS, Chow R, Hamstra SJ: Value of debriefing during simulated crisis management: Oral, Russo SG, Eich C, Barwing J, Nickel EA, Braun U, Graf BM, Timmermann A: Self-reported changes in attitude and behavior after attending a simulation-aided airway management course. 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. Although described in the conscious state and associated with silent reflux, laryngospasm is a problematic reflex which occurs often under general anaesthesia.

Mayo Clinic offers appointments in Arizona, Florida and Minnesota and at Mayo Clinic Health System locations. padding-bottom: 0px; (Staff Anesthesiologist, Department of Anaesthesia, Children's University Hospital, Dublin, Ireland), for kindly reviewing the manuscript; Hlne Mathey-Doret, M.D. 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%. 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. To reverse laryngospasm after surgery with anesthesia, your medical team can perform treatments to relax your vocal cords and ease your symptoms. Nov. 7, 2021. The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. Dry drowning has been explained by mechanisms such as protracted laryngospasm and vagally mediated cardiac arrest triggered by contact of liquid with the upper airways. Fig. ANESTHESIOLOGY 2006; 105:4550, Meier S, Geiduschek J, Paganoni R, Fuehrmeyer F, Reber A: The effect of chin lift, jaw thrust, and continuous positive airway pressure on the size of the glottic opening and on stridor score in anesthetized, spontaneously breathing children. Perianesthetic Management of Hypertrophic Cardiomyopathy, Copyright 2023 American Society of Anesthesiologists. 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. The first step of laryngospasm management is prevention. 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. Airway management training, including management of laryngospasm, is an area that can significantly benefit from the use of simulators and simulation.73These tools represent alternative nonclinical training modalities and offer many advantages: individuals and teams can acquire and hone their technical and nontechnical skills without exposing patients to unnecessary risks; training and teaching can be standardized, scheduled, and repeated at regular intervals; and trainees' performances can be evaluated by an instructor who can provide constructive feedback, a critical component of learning through simulation.7475. Click here for an email preview. acute dystonic reactions; rarely associated with ketamine procedural sedation. However, onset time to effective relief of laryngospasm is shorter than onset time to maximal twitch depression, enabling laryngospasm relief and oxygenation (within 60 s) in less time than time to maximum twitch depression.55Therefore, intramuscular succinylcholine is the best alternative approach if IV access is not readily available.56Another alternative for succinylcholine administration is the intraosseous route. Anesthesiology. As a result, your airway becomes temporarily blocked, making it difficult to breathe or speak. 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. 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. Keep the airway clear and monitor for negative pressure pulomnary oedema. Minimally invasive anti-reflux procedures, Advertising and sponsorship opportunities. 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. In this case, some equipment has high usage demands and becomes scarce throughout the unit. Upper respiratory tract infection (URI) is associated with a twofold to fivefold increase in the risk of laryngospasm.5,9Anesthesiologists in charge of pediatric patients should be aware that the risks associated with a URI in an infant are magnified in this age group, especially in those with respiratory syncytial virus infection.10Children with URI are prone to develop airway (upper and bronchial) hyperactivity that lasts beyond the period of viral infection. ANESTHESIOLOGY 2007; 107:7149, Tait AR, Burke C, Voepel-Lewis T, Chiravuri D, Wagner D, Malviya S: Glycopyrrolate does not reduce the incidence of perioperative adverse events in children with upper respiratory tract infections. The treatment includes opening and clearing the oropharynx, applying CPAP with 100% oxygen, followed by deepening of anaesthesia usually with an i.v . 14%, relative risk 1.2, 95% CI 1.11.3; P= 0.001). 2012 Feb;116(2):458-71. doi: 10.1097/ALN.0b013e318242aae9. However, the acquisition and the mastering of these skills during specialty training and their maintenance during continuing medical education represent a formidable challenge. Finally, third-level studies evaluate the effect of education on patient outcomes. Larson CP Jr. Laryngospasmthe best treatment. #mergeRow-gdpr fieldset label { Prospective studies supported the use of LMA over ETT in children with URI.3031However, these studies were underpowered to detect differences in laryngospasm. Management of refractory laryngospasm. Alterations of upper airway reflexes may occur in several conditions. information highlighted below and resubmit the form. Identifying patients at increased risk for laryngospasm and taking recommended precautions are the most important measures to prevent laryngospasm (fig. In the recent analysis of 189 reports of laryngospasm to the Australian Incident Monitoring Study, one in three patients suffered significant physiological disturbance. ANESTHESIOLOGY 2009; 110:28494, Baraka A: Intravenous lidocaine controls extubation laryngospasm in children. According to Phil Larson: This notch is behind the lobule of the pinna of each ear. If youve had recurring laryngospasms, you should see your healthcare provider to find out whats causing them. People with laryngospasm are unable to speak or breathe. Many methods and techniques of airway manipulation have been proposed. SimBaby is a tetherless simulator designed to help healthcare providers effectively recognize and respond to critically ill pediatric patients. Accessed Nov. 5, 2021. [. 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). Causes: hypocalcemia, painful stimuli . Even though you may feel like you cant breathe, try to remember that the episode will pass. Mayo Clinic does not endorse companies or products. In children, an artificial cough maneuver, including a single lung inflation maneuver with 100% O2immediately before removal of the ETT, is useful at the time of extubation because it delays or prevents desaturation in the first 5 min after extubation in comparison with a suctioning procedure.36Although not demonstrated in this study, this technique could reduce laryngospasm because when the endotracheal tube leaves the trachea, the air escapes in a forceful expiration that removes residual secretions from the larynx. The procedure was expected to be very short, and general anesthesia with inhalational induction and maintenance, but without tracheal intubation, was planned.

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.. However, waiting until hypoxia opens the airway is not recommended, because a postobstruction pulmonary edema or even cardiac arrest may occur.43. On the other hand, attempts to provide positive-pressure ventilation with a facemask may distend the stomach, increasing the risk of gastric regurgitation. Unfortunately, laryngospasms usually happen quickly. Can J Anaesth 2004; 51:45564, Goldmann K, Ferson DZ: Education and training in airway management. Learning breathing techniques can help you remain calm during an episode. Part A - Laryngospasm case study Introduction Laryngospasm is a medical emergency that can happen to any patient undergoing anaesthesia. 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. 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. If you think youve experienced laryngospasm, talk to your healthcare provider. , the overall incidence of respiratory adverse events seems to be higher in children who were awake when their LMA was removed and lower in those who were awake when their endotracheal tube was removed.5In summary, evidence seems to favor deep LMA and awake ETT removal. can occur spontaneously, most commonly associated with extubation or ENT procedures CAUSES Local extubation especially children with URTI symptoms Von Ungern-Sternberg et al. 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. Recognizing laryngospasm - laryngospasm can occur spontaneously and be life-threatening, making it important that you be able to recognize it immediately. Below a cardiac temperature of 28C, the heart may suddenly and spontaneously arrest. He is a co-founder of theAustralia and New Zealand Clinician Educator Network(ANZCEN) and is the Lead for theANZCEN Clinician Educator Incubatorprogramme. anaesthesia: laryngospasm. 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. If you are a Mayo Clinic patient, this could Check out these best-sellers and special offers on books and newsletters from Mayo Clinic Press. 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. 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. It normally passes quickly and is not dangerous, but some . 2. Collins S, Schedler P, Veasey B, Kristofy A, McDowell M. His one great achievement is being the father of three amazing children. As a result, your airway becomes temporarily blocked, making it difficult to breathe or speak. The anesthesiologist assesses that the head/neck could be placed in a more ideal position . Laryngospasm in amyotrophic lateral sclerosis. Elsevier; 2022. https://www.clinicalkey.com. APPENDIX. Breathe in and out through the straw without pausing between the inhale and the exhale. These are usually rare events and recurrence is uncommon, but if it happens, try to relax. 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. Anesth Analg 2007; 104:26570, Bordet F, Allaouchiche B, Lansiaux S, Combet S, Pouyau A, Taylor P, Bonnard C, Chassard D: Risk factors for airway complications during general anaesthesia in paediatric patients. The patient develops laryngospasm and is ventilated by hand-bag. The video and the script are intended to illustrate the proper application of the management algorithm, to illustrate the technical and the nontechnical skills required in clinical practice, and to be a resource for the readers who wish to develop their own training sessions. min-height: 0px; Table 2. can occur spontaneously, most commonly associated with extubation or ENT procedures, extubation especially children with URTI symptoms, intubation and airway manipulation (especially if insufficiently sedated), drugs e.g. Afferent nerves converge in the brainstem nucleus tractus solitarius. margin-right: 10px; First, the introduction of working hour limitations in virtually all Western countries has decreased the number of pediatric cases performed by trainees.71Second, most anesthetics given to children are administered by nonspecialists whose lack of experience and inability to maintain their skill set for children is a problem. This scenario illustrates the potential risks of not managing your resources properly. 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. Assist the patient's inspiratory effort with posi-tive-pressure ventilation with 100% oxygen. Qual Saf Health Care 2005; 14:e3, Fernandez E, Williams DG: Training and the European Working Time Directive: A 7 year review of paediatric anaesthetic trainee caseload data. information and will only use or disclose that information as set forth in our notice of OVERVIEW Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers. So when in doubt, meticulous observation with aggressive preparation may be reasonable. Sci Transl Med 2010; 2:19cm8. The mother volunteered that he was exposed to passive smoking in the home. 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. This means that if nothing has occurred 46 h after the occurrence of a laryngospasm it is likely that the course will be uneventful. By clicking Accept, you consent to the use of ALL the cookies. Description. 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). 5 Many high-acuity medical conditions can induce these. 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. Here are a couple of techniques to try during an attack: Because laryngospasm happens suddenly without warning, theres really no way to prevent it. 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. 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. These preliminary results are interesting and need to be confirmed by further studies. They can determine the cause of your laryngospasms and recommend an appropriate treatment plan. 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. 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. This website uses cookies to improve your experience while you navigate through the website. If complete laryngospasm cannot be rapidly relieved, IV agents should be quickly considered. Paediatr Anaesth 2005; 15:10947, Nawfal M, Baraka A: Propofol for relief of extubation laryngospasm. Laryngospasm. Thus, the potential window for safe administration of general anesthesia is frequently very short. Anaesthesia 2008; 63:3649, Bruppacher HR, Alam SK, LeBlanc VR, Latter D, Naik VN, Savoldelli GL, Mazer CD, Kurrek MM, Joo HS: Simulation-based training improves physicians' performance in patient care in high-stakes clinical setting of cardiac surgery. font-weight: normal; You may opt-out of email communications at any time by clicking on The patient is unconscious and initially breathing easily with an oral airway in place. 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. The diagnosis of laryngospasm is made and treated, only to reveal persistent hypoxemia and negative-pressure pulmonary edema (NPPE). The next line of therapy would be to administer a low dose of succinylcholine (10Y20 mg) to relax the .
