Laryngospasm can happen suddenly and without warning, lasting up to one minute. They can help figure out whats causing them. Paediatr Anaesth 2008; 18:3037. Despite a jaw thrust maneuver, positive pressure ventilation with 100% O2, and administration of two bolus doses (5 mg) of IV propofol (0.6 mg/kg), the obstruction was not relieved and SpO2decreased to 52%. 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. You also have the option to opt-out of these cookies.

ANESTHESIOLOGY 1998; 89:12934, Reber A, Paganoni R, Frei FJ: Effect of common airway manoeuvres on upper airway dimensions and clinical signs in anaesthetized, spontaneously breathing children. 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. 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. 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. Some people may experience recurring (returning) laryngospasms. He is also a Clinical Adjunct Associate Professor at Monash University. 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. 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. Acta Anaesthesiol Scand 1999; 43:10813, Visvanathan T, Kluger MT, Webb RK, Westhorpe RN: Crisis management during anaesthesia: Laryngospasm. Even though you may feel like you cant breathe, try to remember that the episode will pass. The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. Accessed Nov. 5, 2021. Broaddus VC, et al. Laryngospasm treatment depends on the underlying cause. More children who developed laryngospasm were successfully treated with chest compression (73.9%) compared with those managed with the standard method (38.4%; P< 0.001). 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. From: Encyclopedia of . 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.

If the diagnosis is laryngospasm or other vocal cord dysfunction, your doctor may refer you to a speech-language pathologist to help you learn breathing exercises. In: Murray and Nadel's Textbook of Respiratory Medicine. 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.

It may be difficult for a nonspecialist pediatric anesthesiologist to adequately manage an inhalational induction, because of the possibility to fail to manage the airway properly or the inability to recognize and treat early a stridor/laryngospasm. We decided to omit it in the preventive and/or treatment algorithms of laryngospasm, although other authors have included it.3,8,66. 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.

Among all upper airway reflexes, it is the most resistant to deepening anesthesia, whereas the coughing reflex is the most sensitive. 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. Hobaika AB, Lorentz MN. Case scenario: perianesthetic management of laryngospasm in children Drowning is an international public health problem that has been complicated by . During high-fidelity simulation, technical and nontechnical skills can then be integrated and practiced. To confirm the diagnosis, your healthcare provider may look at your vocal cords with a laryngeal endoscope. 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. If positive-pressure ventilation is to be performed, then moderate intermittent pressure should be applied. Accessed Nov. 5, 2021. Like any other crisis, such management requires the application of appropriate knowledge, technical skills, and teamwork skills (or nontechnical skills). Complete airway obstruction is characterized by: Where is the laryngospasm notch? Stimulation of upper airway mucosa also produces cardiovascular (alterations of the arterial pressure, bradycardia, etc.) He had been fasting for the past 6 h.

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. Recognizing laryngospasm - laryngospasm can occur spontaneously and be life-threatening, making it important that you be able to recognize it immediately. However, to our knowledge, no study has evaluated the effect of such a training approach on the management of laryngospasm.

For children with URI, cancellation of elective procedures for a period of 46 weeks was traditionally the rule. A detailed history should be taken to identify the risk factors. 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. So, treatment often involves finding ways to stay calm during the episode. If youve experienced a laryngospasm, schedule an appointment with your healthcare provider.
