Convulsions in the terminally ill elderly can be dangerous. Convulsions in the elderly are often caused by epilepsy. When an elderly person has an epileptic seizure and convulsions, he or she will suddenly open and close his or her mouth, which may lead to tongue bite and blood loss, which can lead to life-threatening hemorrhagic shock. Convulsions in the terminally ill elderly, if they are caused by epilepsy and last for a long period of time, persistent status epilepticus cannot be ruled out. If the patient continues to have convulsions, the brain is highly ischemic and hypoxic, neurons are damaged, and respiration may be affected, putting the patient in danger. Convulsions in the terminally ill elderly may also induce intrapulmonary infections leading to high fever, chills, coughing and other symptoms, which are also very dangerous for the elderly. Convulsions in the terminally ill elderly can also be caused by other factors, such as electrolyte disorders. When a patient has a convulsion, he should seek medical attention or call the emergency center (120) for help, and cooperate with the physician to take reasonable treatment according to the patient’s condition, such as oxygen, anti-epileptic, anti-infection, rehydration and symptomatic treatment.
