Twitching of hands and feet in children is often caused by epilepsy, metabolic disorders, hyperthermic convulsions, encephalitis, etc. Active medical attention is needed to clarify the cause, control the symptoms of twitching and improve the prognosis. Common causes and treatments 1, epilepsy: sudden abnormal discharge of neurons in the brain, resulting in transient brain dysfunction, children can be manifested as hand and foot convulsions. Anti-epileptic drugs, such as lamotrigine, levetiracetam, topiramate, oxcarbazepine, etc., can be applied as prescribed by the doctor. If the seizures cannot be controlled and the foci are clearly localized, unilateral localized lesions or cortical abnormalities can be surgically removed; 2. Metabolic disorders: such as hypoglycemia and calcium deficiency can lead to metabolic disorders in the body and hand and foot convulsions. It can be treated by adjusting the diet and taking calcium tablets. If the blood sugar is low, the diet can be increased appropriately by eating more foods with high calories, such as sugar, chocolate, cakes, etc., and foods with high calcium content, such as milk, eggs, fish, shrimps, etc. You can also take calcium tablets for calcium supplementation to alleviate the symptoms of children’s hand and foot twitching; 3, hyperthermia convulsions: high body temperature, stimulating the abnormal discharge of the cerebral cortex, resulting in convulsions of the hands and feet. This condition should be promptly visited to the hospital, following medical advice to apply sedatives, such as diazepam, phenobarbital, etc., antipyretic agents such as ibuprofen, acetaminophen; 4, encephalitis: caused by a variety of viral or bacterial infections, often there is a history of upper respiratory tract infection. Severe symptoms can result in convulsive seizures, which in turn can lead to twitching of the child’s arms and legs. You should perform routine blood tests, head CT, lumbar puncture tests and other tests to clarify the diagnosis and then hospitalization, follow medical advice to apply antiviral drugs, such as acyclovir, ganciclovir, ribavirin and other intravenous drips, can apply mannitol to control cerebral edema, sedation immunoglobulin to improve the immunity of the child. When a child has hand or foot convulsions, place the child on a hard bed or a flat surface, lie on his or her side, open the collar, do not hold the child to restrict his or her hand or foot convulsions, and remove obstacles and dangerous objects around the child to prevent the child from accidental injury. At the same time, do not stuff anything inside the child’s mouth, such as chopsticks, tongue depressors, towels, to avoid accidental inhalation, resulting in choking episodes, and promptly send the child to the hospital for emergency medical treatment.
