What are the treatments for laryngopharyngeal spasm?

The throat is the most important breathing passage for people and the only passage for people to eat. The pharyngeal tissue is a relatively complex tissue that plays an important role. It is the processing center for people to make sounds and separate food from the trachea. Therefore, lesions in the throat will have a greater impact on the body. For example, pharyngeal spasm is a relatively serious disease. Let’s take a look at the treatments for pharyngeal spasm.

Laryngeal spasm refers to the reflex spasm and contraction of the laryngeal muscles, which causes the vocal cords to retract and the glottis to partially or completely close, resulting in varying degrees of dyspnea or even complete airway obstruction in the patient. Ordinary inflammation will not cause laryngeal spasm. Laryngospasm is just a stress response. Improper handling has a high mortality rate.

If laryngeal spasm occurs, the following measures can be taken to treat it:

1. Give pure oxygen inhalation and, if necessary, pure oxygen positive pressure ventilation until the patient wakes up and laryngeal spasm disappears;

2. If the anesthesia is too shallow, use intravenous or inhaled anesthetics to deepen the anesthesia until laryngeal spasm and other reflexes disappear.

3. If necessary, short-acting muscle relaxants can be given and endotracheal intubation should be performed if necessary. It is generally believed that patients with laryngeal spasm after extubation with SpO2 < 85% require further treatment. In addition, the anticholine drug atropine can be used to reduce glandular secretions and reduce irritation of oropharyngeal secretions.

Emergency treatment

1. Inhale pressurized pure oxygen through a mask.

2. Gently lifting your jaw can relieve mild laryngeal spasm.

3. Immediately stop all stimulation and surgical procedures.

4. Immediately ask others for help.

5. Deepening anesthesia can relieve mild to moderate laryngeal spasm. The commonly used method is. Administer 20% of the induction dose intravenously or increase the concentration of inhaled anesthetic.

6. Expose and clear throat secretions to keep the airway open.

7. For severe laryngeal spasm, in emergency situations, cricothyroid membrane puncture with a needle of size 16 or larger can be used to provide oxygen or high-frequency ventilation.

8. For severe laryngeal spasm, succinylcholine 1.0-1.5 mg/kg can be used, intravenously injected or 4.0 mg/kg intramuscularly injected, followed by tracheal intubation.
