Laryngeal spasm

Introduction Laryngospasm refers to the reflex spasm of the larynx muscle, which allows the vocal cords to adduct, and the glottis is partially or completely closed, resulting in varying degrees of dyspnea or even complete airway obstruction.

Cause

1. Intra-airway operation, suction under light anesthesia, placement of oropharynx or nasopharyngeal airway, endotracheal intubation or extubation stimulation of the throat.

2. Inflammation induced by blood, secretions or vomiting, refluxing stomach contents, etc. in the airway. The ancient training is: eat nothing, sleep without words. When you are laughing at dinner, it is easy for food and soup to enter the airway, causing coughing and even causing throat, so that the patient's glottis is locked, not sucking in, not exhaling, not speaking, and suffocating. In this critical moment, if you can click on the Tiantu points in time, you can remove the throat and make the patient turn to safety. The acupoint is located 2 inches below the larynx, just as the center of the sternal fossa.
