The child twitches when excited

When children are young, they often suffer from some diseases. These diseases may be caused by poor development during the fetal period, or they may be caused by some diseases during the growth process. So, if a child has convulsions when he is excited, what disease is it? Some parents believe that the disease that causes children to convulse is caused by calcium deficiency. In fact, there is another disease that can also cause convulsions in children - hyperventilation syndrome.

Hyperventilation syndrome (HVS) is a group of syndromes caused by abnormal regulation of the respiratory center and hyperventilation exceeding physiological metabolic requirements. It is often manifested by difficulty breathing, numbness of the limbs, dizziness and blurred vision. In severe cases, there may be symptoms such as syncope and convulsions. During an attack, the patient will feel an accelerated heartbeat, palpitations, and sweating. Because he cannot feel his breathing, he speeds up his breathing, which causes the carbon dioxide in the body to be continuously discharged and the concentration to be too low, causing symptoms such as secondary respiratory alkali poisoning, also known as respiratory alkali poisoning syndrome, respiratory neurological syndrome, and hyperventilation syndrome.

Clinical manifestations

When the disease occurs, breathing becomes deeper and faster, and the patient complains of difficulty breathing; chest tightness, pressure or suffocation, and may have chest pain, palpitations, tachycardia, etc. Numbness of the extremities and face, convulsions of the hands and feet, muscle spasms and even rigidity, and may also occur as well as headaches, dizziness, and impaired consciousness. There were no positive signs on physical examination.

diagnosis

1. On the premise of excluding other organic diseases, a clinical diagnosis is made based on the presence of psychogenic factors before the onset of the disease, typical symptoms, respiratory alkali poisoning confirmed by arterial blood gas analysis, and partial or complete induction of major symptoms by hyperventilation provocation test. More common in women.

2. The hyperventilation provocation test uses an end-tidal carbon dioxide analyzer to induce instability in the patient's respiratory regulation function by allowing the patient to voluntarily hyperexhale for 3 minutes (60 times/minute), causing hyperventilation and respiratory alkali poisoning, which can fully or partially reproduce important symptoms.

3. Experimental treatment: try letting the patient inhale carbon dioxide gas to prevent the occurrence of symptoms.
