How to effectively treat pharyngeal spasm

How to treat pharyngeal spasm? First of all, we should pay attention to understanding the cause. For example, common blood secretions in the airway or vomiting and regurgitation of gastric contents can easily cause irritation and cause the disease. The common treatment method now is surgery or lidocaine and other drug treatments.

1. Causes of pharyngeal spasm

1. Irritation to the throat caused by intra-tracheal operations, suctioning of sputum under light anesthesia, placement of oropharyngeal or nasopharyngeal airways, endotracheal intubation or extubation.

2. It is caused by stimulation from blood, secretions in the airway, vomiting, reflux of gastric contents, etc.

3. Caused by central brainstem lesions, such as brainstem vascular embolism, tumors, pontocerebellar diseases, syringobulbar disease, diffuse cerebral arteriosclerosis, etc.

Differential diagnosis of pharyngolaryngitis

Sore throat: It is the main symptom of oropharyngeal and laryngopharyngeal lesions, characterized by redness, swelling and pain in the throat and discomfort when swallowing, also known as "laryngeal congestion". Sore throat is seen in Western medicine such as acute tonsillitis, acute pharyngitis and simple laryngitis, peritonsillar abscess, etc. It is also a symbol of dry mouth, cold and illness.

The throat muscles twitch, which may manifest as mild inspiratory stridor in mild cases and complete upper airway obstruction in severe cases. Inspiratory dyspnea and laryngeal stridor often occur suddenly at night, with panic, cold sweats, cyanosis, and suffocation, but the symptoms usually disappear immediately after a deep breath. The attack lasts for a short time, only a few seconds to 1 to 2 minutes, and can recur and occur continuously. There were no symptoms such as hoarseness or fever during or after the attack. Laryngoscopy usually shows no abnormalities.

Treatment and prevention of laryngopharyngeal spasm

1. Tracheal intubation and surgical procedures should be avoided under light anesthesia, and hypoxia and carbon dioxide accumulation should be avoided.

2. It is best to extubate when the patient is fully awake.

3. Lidocaine can be used to prevent laryngospasm after extubation after tonsillectomy. Intravenous injection of 1-2 mg/kg 1-2 minutes before extubation can significantly reduce the incidence of cough and laryngeal spasm in children. However, swallowing action must be ensured at this time.
