Common triggers of reflex laryngeal response during anesthesia are secretions, blood, insertion of an oropharyngeal airway suction catheter, and laryngoscopy. Identifying patients at increased risk for laryngospasm and taking recommended precautions are the most important measures to prevent laryngospasm (fig. It should be suspected whenever airway obstruction occurs, particularly in the absence of an obvious supraglottic cause. PERIOPERATIVE laryngospasm is an anesthetic emergency that is still responsible for significant morbidity and mortality in pediatric patients.1It is a relatively frequent complication that occurs with varying frequency dependent on multiple factors.2,,5Once the diagnosis has been made, the main goals are identifying and removing the offending stimulus, applying airway maneuvers to open the airway, and administering anesthetic agents if the obstruction is not relieved.

The next step in management depends on whether laryngospasm is partial or complete and if it can be relieved or not. 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). To confirm the diagnosis, your healthcare provider may look at your vocal cords with a laryngeal endoscope. ANESTHESIOLOGY 2005; 103:11428, Patel RI, Hannallah RS, Norden J, Casey WF, Verghese ST: Emergence airway complications in children: A comparison of tracheal extubation in awake and deeply anesthetized patients. An example of such a simulation-training scenario of a laryngospasm, including a description of the session and the debriefing, can be found in the appendix. Hold your breath for five seconds, then repeat until the laryngospasm stops. Here are a couple of techniques to try during an attack: Because laryngospasm happens suddenly without warning, theres really no way to prevent it. Exhale through pursed lips. The anesthesiologist assesses that the head/neck could be placed in a more ideal position . Unfortunately, laryngospasms usually happen quickly. padding-bottom: 0px; They can help figure out whats causing them. Table 2. , otolaryngology surgery).2,5,,7Many factors may increase the risk of laryngospasm. width: auto; 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).

The question of whether using propofol or muscle relaxant first is a matter of timing. To reverse laryngospasm after surgery with anesthesia, your medical team can perform treatments to relax your vocal cords and ease your symptoms. He coordinates the Alfred ICUs education and simulation programmes and runs the units educationwebsite,INTENSIVE. 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. Anesthesiology. ,5emergent procedures had a moderately higher risk than elective procedures for perioperative respiratory adverse events, including laryngospasm (17%vs. Laryngospasm remains the leading cause of perioperative cardiac arrest from respiratory origin in children.1, The upper airway has several functions (swallowing, breathing, and phonation) but protection of the airway from any foreign material is the most essential. Curr Opin Anaesthesiol 2009; 22:38895, Owen H: Postextubation laryngospasm abolished by doxapram. Among all upper airway reflexes, it is the most resistant to deepening anesthesia, whereas the coughing reflex is the most sensitive. Accessed Nov. 5, 2021.

Laryngospasm (luh-RING-go-spaz-um) is a transient and reversible spasm of the vocal cords that temporarily makes it difficult to speak or breathe. 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. 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. It is still debated whether tracheal extubation should be performed in awake or deeply anesthetized children to decrease laryngospasm. can occur spontaneously, most commonly associated with extubation or ENT procedures CAUSES Local extubation especially children with URTI symptoms Manipulation of the airway at an insufficient depth of anesthesia is a major cause of laryngospasm. 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..
