Laryngospasm was treated by 50 mg propofol and manual positive pressure mask ventilation with 100% inspired oxygen. Broaddus VC, et al. A new episode of laryngospasm was immediately suspected. He has completed fellowship training in both intensive care medicine and emergency medicine, as well as post-graduate training in biochemistry, clinical toxicology, clinical epidemiology, and health professional education. Fig. 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. 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.

He is one of the founders of theFOAMmovement (Free Open-Access Medical education) and is co-creator oflitfl.com,theRAGE podcast, theResuscitologycourse, and theSMACCconference. It is a primitive protective airway reflex that exists to . Fig. 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%.

He is an internationally recognised Clinician Educator with a passion for helping clinicians learn and for improving the clinical performance of individuals and collectives. 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. Learn more about the symptoms here. Inexperience of the anesthetist is also associated with an increased incidence of laryngospasm and perioperative respiratory adverse events.2,5,18Some factors are associated with a lower risk of laryngospasm: IV induction, airway management with facemask, and inhalational maintenance of anesthesia.5Induction and emergence from anesthesia are the most critical periods. ANESTHESIOLOGY 2001; 95:299306, Lakshmipathy N, Bokesch PM, Cowen DE, Lisman SR, Schmid CH: Environmental tobacco smoke: A risk factor for pediatric laryngospasm. Laryngospasm treatment depends on the underlying cause. In the study by von Ungern-Sternberg et al. 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. Table 1. Muscles involved: lateral cricoarytenoid, thyroarytenoids (both from recurrent laryngeal), crycrothyroid (from external branch of superior laryngeal). Second-level studies attempt to document the transfer of skills to the clinical setting and patient care. Laryngospasm is identied by varying degrees of airway obstruction with paradoxical chest move-ment, intercostal recession and tracheal tug. If you have any of the conditions listed above, talk to your healthcare provider about ways to reduce your risk for laryngospasms. 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. OVERVIEW Laryngospasm is potentially life-threatening closure of the true vocal chords resulting in partial or complete airway obstruction unresponsive to airway positioning maneuvers. privacy practices. In: Murray and Nadel's Textbook of Respiratory Medicine. Therefore, the injection of IV succinylcholine was required to treat this persistent laryngospasm. The patient develops laryngospasm and is ventilated by hand-bag. Laryngospasm is a frightening condition that happens when your vocal cords suddenly seize up, making breathing more difficult. The authors thank Frances O'Donovan, M.D., F.F.A.R.C.S.I. Laryngospasm is a sudden spasm of the vocal cords. Table 2. People with laryngospasm are unable to speak or breathe. Manual facemask ventilation became difficult with an increased resistance to insufflation and SpO2dropped rapidly from 98% to 78%, associated with a decrease in heart rate from 115 to 65 beats/min. 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. A competence-based training that includes a structured curriculum and regular workplace-based assessment may help mitigate the effects of caseload reduction. This website uses cookies to improve your experience while you navigate through the website. A laryngospasm is a muscle spasm in the vocal cords that can lead to problems with speaking and breathing. Laryngospasm is usually defined as partial or complete airway obstruction associated with increasing abdominal and chest wall efforts to breathe against a closed glottis. Khanna S (expert opinion). 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. 1).3The second step relies on the emergent treatment of established laryngospasm occurring despite precautions (fig. PEEP! Learning outcomes are difficult to measure.

The question of whether using propofol or muscle relaxant first is a matter of timing. Anesthesiology. 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. Laryngospasm. This means that if nothing has occurred 46 h after the occurrence of a laryngospasm it is likely that the course will be uneventful. Mayo Clinic does not endorse companies or products. Laryngospasm scenario. More needed than oxygen! Policy. Br J Anaesth 1998; 81:6925, Krodel DJ, Bittner EA, Abdulnour R, Brown R, Eikermann M: Case scenario: Acute postoperative negative pressure pulmonary edema. You may opt-out of email communications at any time by clicking on 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. Realistic training with high-fidelity mannequins and other types of simulations represent unique educational tools that can be fully integrated in a residency program based on competency.72Similarly, simulation-based education is being increasingly used for continuing medical education. 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. Case Scenario Perianesthetic Management of Laryngospasm In; Hazard Identification and Risk Assessment; Permit to Work Ensuring a Safe Work Environment Introduction Industrial Workers Face Many Hazards in Their Daily Routines; Health Surveillance Employer's Pack; Incidence and Associated Factors of Laryngospasm Among Pediatric The next line of therapy would be to administer a low dose of succinylcholine (10Y20 mg) to relax the . In the case of laryngospasm, basic appropriate airway manipulations such as chin lift, jaw thrust, and oral airway insertion in combination with CPAP can be demonstrated and practiced with these models. The next step in management depends on whether laryngospasm is partial or complete and if it can be relieved or not. 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. Acta Anaesthesiol Scand 2009; 53:19, Larson CP Jr: Laryngospasmthe best treatment. These cookies do not store any personal information. Anesthesia was then maintained by facemask with 2.0% expired sevoflurane in a mixture of oxygen and nitrous oxide 50/50%. Use of suxamethonium without intravenous access for severe laryngospasm. It is still debated whether tracheal extubation should be performed in awake or deeply anesthetized children to decrease laryngospasm.

This situation creates a risk of bronchopulmonary infection, chronic cough, and bronchospasm. Acid reflux may cause a few drops of stomach acid backwash to touch the vocal cords, setting off the spasm. As your vocal cords slowly relax and open, you may hear a high-pitched sound (stridor). Part A - Laryngospasm case study Introduction Laryngospasm is a medical emergency that can happen to any patient undergoing anaesthesia. The cause of vocal cord spasms is often unknown, and it is usually in response to a trigger such as anxiety or acid reflux. Sufficient depth of anesthesia must be achieved before direct airway stimulation is initiated (oropharyngeal airway insertion). (Staff Anesthesiologist, Department of Anaesthesia, Children's University Hospital, Dublin, Ireland), for kindly reviewing the manuscript; Hlne Mathey-Doret, M.D. The afferent nerve involved in laryngeal closure reflex is the superior laryngeal nerve.
