Which of the following is a sign of laryngospasm?

Stridor is a clinical manifestation associated with laryngospasm, characterized by a high-pitched, wheezing sound resulting from turbulent airflow through narrowed or obstructed airways. In the case of laryngospasm, the vocal cords involuntarily contract, partially or completely occluding the airway. This spasm can lead to increased upper airway resistance, resulting in the stridorous sound that is indicative of an upper airway blockage.

Laryngospasm can indeed present with other symptoms, but stridor is particularly significant because it represents the audible sign of restricted airflow, making it a crucial indicator for clinicians assessing airway management. Recognizing stridor allows for timely interventions to secure the airway and prevent respiratory distress. This understanding is vital for those in the field of oral and maxillofacial surgery and anesthesia, where managing airway complications effectively is essential for patient safety.
