Laryngeal spasm
Introduction
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
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.

Lighter throat can be expressed as mild inspiratory wheezing, and severe upper airway obstruction can occur. Although the former is not a fatal episode, improper treatment can quickly develop into the latter. Complete upper airway obstruction is characterized by the disappearance of inspiratory wheezing. It is especially important that this "silent" obstruction cannot be mistaken for clinical improvement.

1. Itchy throat and cough. Itching of the throat is characterized by itchy throat, itching cough, the more cough, the cough point above the glottis, the chest through the lungs without lesions.
2. Laryngeal muscle weakness The vocal cord closure insufficiency refers to a disease in which the laryngeal muscles are incapable of causing hypokinetic glottic dyskinesia during vocalization, as well as laryngeal muscle weakness and vocal fatigue.
3. There is a phlegm in the throat and it is a clinical manifestation of chronic pharyngitis. The main symptoms of patients with chronic laryngitis are hoarseness, dry throat, sore throat when speaking, and often sputum adhesion due to increased secretion from the throat.
4. Throat throat sore throat is a symptom of hard infarction, commonly used drugs bone. Throat in the throat may also be a local manifestation of chronic pharyngitis.
