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. URI = upper respiratory tract infection. The question of whether using propofol or muscle relaxant first is a matter of timing. information is beneficial, we may combine your email and website usage information with Breathe in and out through the straw without pausing between the inhale and the exhale. The vocal cords are two fibrous bands inside the voice box (larynx) at the top of the windpipe (trachea). 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. The patient will then develop worsened hypotension, requiring the start of an epinephrine infusion. 2012 Feb;116(2):458-71. doi: 10.1097/ALN.0b013e318242aae9. Assist the patient's inspiratory effort with posi-tive-pressure ventilation with 100% oxygen. 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.

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. , otolaryngology surgery).2,5,,7Many factors may increase the risk of laryngospasm. The onset of a vocal cord spasm is sudden, and just as suddenly, it goes away, usually after . and bronchomotor reflexes, indicating that not only skeletal but also smooth muscles are involved in upper airway reflexes.19.

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. 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. 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.

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.. Use of suxamethonium without intravenous access for severe laryngospasm. For the management of laryngospasm in children, this task is complicated by two facts. Lancet 2010; 376:77383, Murat I, Constant I, Maud'huy H: Perioperative anaesthetic morbidity in children: A database of 24,165 anaesthetics over a 30-month period. These are usually rare events and recurrence is uncommon, but if it happens, try to relax. min-height: 0px; PubMed PMID: Salem MR, Crystal GJ, Nimmagadda U. } Here are some important features to keep in mind: Complete blockage may present as just apnea; Can be preceded by high-pitched inspiratory stridor, followed by complete airway obstruction As they correctly point out, laryngospasm is a serious complication and must be promptly managed to avoid serious physiological disturbance. 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. Anesth Analg 2002; 94:4949, Reber A, Bobbi SA, Hammer J, Frei FJ: Effect of airway opening manoeuvres on thoraco-abdominal asynchrony in anaesthetized children. Risk Factors Associated with Perioperative Laryngospasm, Young age is one of the most important risk factors. 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. APPENDIX. We strongly encourage future studies assessing the effect of training and simulation on the management of laryngospasm in children at various levels of outcomes. 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. clear: left; 1998-2023 Mayo Foundation for Medical Education and Research (MFMER). Vocal cord dysfunction. Review/update the Laryngospasm usually isnt life-threatening, but it can be a terrifying experience. Table 2. They can perform an examination and find out if there are ways to prevent laryngospasm from happening in the future. Anaphylaxis (+/- Laryngospasm) A 7-year-old male presents with wheeze, rash and increased WOB after eating a birthday cake. Evidence on this subject is scarce, but the study by von Ungern-Sternberg et al. Children are more prone to laryngospasm than adults, with laryngospasm being reported more commonly in children (17.4/1,000) than in the general population (8.7/1,000).2,5,,7In fact, the incidence of laryngospasm has been found to range from 1/1,000 up to 20/100 in high-risk surgery (i.e. Rev Bras Anestesiol. Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers. Muscle relaxants are usually administered when initial steps of laryngospasm treatment have failed to relax the vocal cords. 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).

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. A detailed history should be taken to identify the risk factors. 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%. Laryngospasm in amyotrophic lateral sclerosis. The onset of a vocal cord spasm is sudden, and just as suddenly, it goes away, usually after a few minutes. Avoid breathing in through your nose. We do not endorse non-Cleveland Clinic products or services. The laryngospasm abates, and the patient becomes easier to ventilate. Hobaika AB, Lorentz MN. This situation creates a risk of bronchopulmonary infection, chronic cough, and bronchospasm. A "can't ventilate, can't intubate" scenario may be prolonged when rocuronium is administered. There is a problem with Curr Opin Anaesthesiol 2009; 22:38895, Owen H: Postextubation laryngospasm abolished by doxapram.

The treatment includes opening and clearing the oropharynx, applying CPAP with 100% oxygen, followed by deepening of anaesthesia usually with an i.v . It is most commonly occurring on induction or emergence phases and can have serious life threatening consequences. The next line of therapy would be to administer a low dose of succinylcholine (10Y20 mg) to relax the . PubMed PMID: 19669024. GERD: Can certain medications make it worse? font-weight: normal; In this case, some equipment has high usage demands and becomes scarce throughout the unit. 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. The use of desflurane during maintenance of anesthesia appeared to be associated with a significant increase in perioperative respiratory adverse events, including laryngospasm, compared with sevoflurane and isoflurane.5Isoflurane appeared to produce laryngeal effects similar to sevoflurane.5.

In the largest study published in the literature (n = 136,929 adults and children), the incidence of laryngospasm was 1.7% in 09 yr-old children and only 0.9% in older children and adults.7The highest incidence (more than 2%) was found in preschool age groups. As a result, your airway becomes temporarily blocked, making it difficult to breathe or speak. The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. ANESTHESIOLOGY 1963; 24:585, Al-Metwalli RR, Mowafi HA, Ismail SA: Gentle chest compression relieves extubation laryngospasm in children. Alterations of upper airway reflexes may occur in several conditions. CPAP = continuous positive airway pressure; FiO2= fractional inspired oxygen tension; IM = intramuscular; PACU = postanesthesia care unit. This is because your vocal cords are contracted and closed tight during a laryngospasm. The . . Therefore, the injection of IV succinylcholine was required to treat this persistent laryngospasm. The purpose of this case scenario is to highlight keypoints essential for the prevention, diagnosis, and treatmentof laryngospasm occurring during anesthesia. 5 of 7 This document is not intended to provide a comprehensiv e discussion of each drug. Jpn J Physiol 2000; 50:314, Thompson DM, Rutter MJ, Rudolph CD, Willging JP, Cotton RT: Altered laryngeal sensation: A potential cause of apnea of infancy. tracheal tug, indrawing), vomiting or desaturation. 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. The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. Plan A:" 3.5 ETT ready, size 1 Macintosh laryngoscope blade" Small orange Bougie (pre bent), have a size 1 Miller blade available" Have a shoulder roll ready, but I wont put it in place" Have a white guedel airway available if I am having difculty with ventilation" If that doesnt work I will do the 2 person technique" More needed than oxygen! 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. Last reviewed by a Cleveland Clinic medical professional on 02/11/2022.
