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. 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. The progressive signs and symptoms are shivering (36C), confusion, disorientation, introversion (35C), amnesia (34C), cardiac arrhythmias (33C), clouding of consciousness (33-30C), LOC (30C), ventricular fibrillation (VF) (28C), and death (25C).

Prospective studies supported the use of LMA over ETT in children with URI.3031However, these studies were underpowered to detect differences in laryngospasm.

Am J Respir Crit Care Med 1998; 157:81521, von Ungern-Sternberg BS, Boda K, Schwab C, Sims C, Johnson C, Habre W: Laryngeal mask airway is associated with an increased incidence of adverse respiratory events in children with recent upper respiratory tract infections. These risk factors can be patient-, procedure-, and anesthesia-related (table 1). For children with URI, cancellation of elective procedures for a period of 46 weeks was traditionally the rule. The anesthesiologist assesses that the head/neck could be placed in a more ideal position . Stimulation of upper airway mucosa also produces cardiovascular (alterations of the arterial pressure, bradycardia, etc.) 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.

Laryngospasm treatment depends on the underlying cause. PubMed PMID: Salem MR, Crystal GJ, Nimmagadda U. Use of suxamethonium without intravenous access for severe laryngospasm. Laryngospasm is usually defined as partial or complete airway obstruction associated with increasing abdominal and chest wall efforts to breathe against a closed glottis.3,5,7In both partial and complete laryngospasm, signs of varying degrees of airway obstruction, such as suprasternal retraction, supraclavicular retractions, tracheal tug, paradoxical chest, and abdominal movements may be seen.3In addition, inspiratory stridor may be heard in partial laryngospasm but is absent in complete spasm. The anesthesia staff has called for the fiberoptic intubation set and is preparing to perform fiberoptic intubation. It is most commonly occurring on induction or emergence phases and can have serious life threatening consequences. However, to our knowledge, no study has evaluated the effect of such a training approach on the management of laryngospasm. 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. Rutt AL, et al. Laryngospasm, particularly during inhalational induction and after extubation, is an important cause of apnea that all anesthesiologists who care for pediatric patients should understand and anticipate. Here are a couple of techniques to try during an attack: Because laryngospasm happens suddenly without warning, theres really no way to prevent it. ANESTHESIOLOGY 1963; 24:585, Al-Metwalli RR, Mowafi HA, Ismail SA: Gentle chest compression relieves extubation laryngospasm in children. As a result, your airway becomes temporarily blocked, making it difficult to breathe or speak. It should be suspected whenever airway obstruction occurs, particularly in the absence of an obvious supraglottic cause. Designing an effective simulation scenario requires careful planning and can be broken into several steps.

If complete laryngospasm cannot be rapidly relieved, IV agents should be quickly considered. This site uses Akismet to reduce spam.

Common triggers of reflex laryngeal response during anesthesia are secretions, blood, insertion of an oropharyngeal airway suction catheter, and laryngoscopy. They are most likely located in the medullary neuronal network rather than in the brainstem.2223The higher center seems to regulate upper airway reflexes.

The purpose of this case scenario is to highlight key points essential for the prevention, diagnosis, and treatment of laryngospasm occurring during anesthesia. Some people may experience recurring (returning) laryngospasms. 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.
