Laryngospasms can be frightening, whether youve experienced them before or not. 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).

Designing an effective simulation scenario requires careful planning and can be broken into several steps. Thus, the potential window for safe administration of general anesthesia is frequently very short. On the other hand, attempts to provide positive-pressure ventilation with a facemask may distend the stomach, increasing the risk of gastric regurgitation. If laryngospasms are due to anxiety, then anti-anxiety meds can help ease your spasms. Review/update the Mayo Clinic does not endorse any of the third party products and services advertised.

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. Acta Anaesthesiol Scand 2009; 53:19, Larson CP Jr: Laryngospasmthe best treatment. It is still debated whether tracheal extubation should be performed in awake or deeply anesthetized children to decrease laryngospasm. Learning objectives should be based on recommended management algorithms and used as inputs and events embedded into one (or several) case scenario that form the basis for the simulated exercise. 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. Laryngospasm is identied by varying degrees of airway obstruction with paradoxical chest move-ment, intercostal recession and tracheal tug. The brainstem nucleus tractus solitarius is not only an afferent portal, but has interneurons that play an essential role in the genesis of upper airway reflexes.19Little is known about the centers that regulate and program these reflexes. The patient develops laryngospasm and is ventilated by hand-bag. Symptoms can be mild or severe.

Pediatr Pulmonol 2010; 45:4949, Afshan G, Chohan U, Qamar-Ul-Hoda M, Kamal RS: Is there a role of a small dose of propofol in the treatment of laryngeal spasm? A laryngospasm is a muscle spasm in the vocal cords that can lead to problems with speaking and breathing. The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. The afferent nerve involved in laryngeal closure reflex is the superior laryngeal nerve. 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.

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. An IV line was obtained at 11:15 PM, while the child was manually ventilated. 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.

The onset of a vocal cord spasm is sudden, and just as suddenly, it goes away, usually after a few minutes. Recently, a new technique with gentle chest compression has been proposed as an alternative to standard practice for relief of laryngospasm.47In this before-after study, extubation laryngospasm was managed with standard practice (CPAP and gentle positive pressure ventilation via a tight-fitting facemask with 100% O2via facemask) during the first 2 yr of the study, whereas in the following 2 yr, laryngospasm was managed with 100% O2and concurrent gentle chest compression. 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.
