laryngospasm
Introduction
Throat introduction The throat (laryngospasm) refers to the reflex sacral contraction of the larynx muscle, which causes the vocal cords to adduct, and the glottis is partially or completely closed, resulting in different degrees of dyspnea or even complete airway obstruction. basic knowledge The proportion of illness: 0.05-0.08% Susceptible people: no specific population Mode of infection: non-infectious Complications: neonatal throat wheezing
Cause
Throat cause
1, airway operation, suction under light anesthesia, placement of oropharynx or nasopharyngeal airway, tracheal 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.
Prevention
Throat prevention
1. Intubation and surgical procedures should be avoided at the time of shallow anesthesia, and hypoxia and carbon dioxide accumulation should be avoided.
2. It is best to perform the extubation while the patient is fully awake.
3. Lidocaine can be used to prevent the throat after extubation after tonsillectomy. 1 to 2 minutes before extubation, intravenous injection of 1 ~ 2mg / kg can significantly reduce the incidence of cough and throat in children. However, there must be a swallowing action at this time.
Complication
Throat complications Complications, neonatal throat wheezing
The throat is also one of the complications of anesthesia, which can cause serious consequences if not handled properly. Often occurs in shallow anesthesia and after removal of the tracheal tube, especially after pediatric upper airway surgery. For example, the incidence of tonsillectomy is about 20%. It is generally believed that when the depth of anesthesia is too shallow to prevent laryngeal reflex, secretions or blood irritating vocal cords can cause throat, oropharyngeal airway, direct laryngoscope, tracheal intubation operation, etc. In the throat, surgery under light anesthesia can sometimes cause a reflex throat. For patients who are not fully awake, the throat is most likely to occur after tracheal extubation.
Symptom
Throat symptoms common symptoms dyspnea newborn throat wheezing inhalation chest throat breathing throat
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.

Endoscopy is available.
