Epilepsy is a chronic disease characterized by transient brain dysfunction caused by sudden abnormal discharge of brain neurons. When a patient has an acute attack, several emergency measures should be taken to prevent injury:

1. During an epileptic seizure, the patient should lie flat, with the head turned to one side or on their side, to keep the airway clear and prevent the inhalation of vomit or secretions into the respiratory tract.

2. Be aware of the surrounding environment to prevent the patient from bumping into tables and chairs, causing secondary injuries. Closely observe the patient's consciousness, breathing, and pulse.

3. Loosen the patient's collar and belt to reduce resistance in the respiratory tract, and place a gauze-wrapped tongue depressor between the teeth to prevent tongue biting and vocalization.

4. Observe whether the patient shows symptoms of increased intracranial pressure and follow medical advice for medication when necessary. Additionally, for persistent epileptic seizures, call emergency services promptly for treatment.
