What happens when a child has a fever and convulsions?

The physical condition of many children is something that many parents need to pay attention to. Children are small and their immunity is naturally not as high as that of adults, so they are very easy to get sick. If parents do not pay attention, it can easily cause serious consequences. Some parents will find that their children have convulsions when they have a fever. What is going on? Then let’s ask an authoritative expert to explain it to you.

At present, clinically, convulsions are mainly divided into five types according to their manifestations:

1. Minor seizures

It is more common than other types, with manifestations mainly on the head and face, without limb rigidity or clonus. During the attack, the movement phenomenon is mild, and the convulsion is weak and limited. It may manifest as respiratory arrest, eye deviation, eyelid twitching, lip tremor, sucking and swallowing, pupil dilation, sometimes accompanied by abnormal crying and laughing, or only autonomic nervous system symptoms, and sometimes accompanied by limb pedaling, stepping, swimming and other movements.

2. Multifocal clonic seizures

This type of convulsion is migratory and has no fixed sequence. During the attack, the clonic movement quickly shifts from one limb to another, or from one side to the other. Long-term focal clonic movement is limited to one limb or the upper and lower limbs on the same side before starting in other parts.

3. Focal clonic seizures

This type of convulsion begins in one limb or one side of the face and can spread to other parts of the same side. There is usually no disturbance of consciousness. During the attack, localized high-amplitude sharp waves can be found on one side near the central sulcus, and may spread to the adjacent area of ​​the same hemisphere or the opposite side. Mild localized seizures are sometimes difficult to identify, such as slight tremor or rigidity of one limb or finger (toe), strange limb movements, such as pendulum-like movements of the upper limbs, pedaling-like movements of both lower limbs, etc.

4. Tonic convulsions

It manifests as extension and stiffness of the whole body, accompanied by respiratory arrest, upward squinting of the eyes, and in a few cases, generalized tonic attacks. This type is more common in premature infants and often indicates organic brain damage.

5. Myoclonic seizures

This type is rare clinically and often indicates diffuse brain damage, manifested as rapid pulling movements of the upper and (or) lower limbs occurring simultaneously, and the electroencephalogram often shows no special morphological abnormalities.
