1. Protect the tongue. It is best to place a gauze wrapped tongue depressor or hollow rubber stick between the patient’s upper and lower molars when the aura symptoms appear to prevent the patient from biting his or her tongue during the clonic phase. Do not put it between the incisors to avoid blocking the airway or losing the incisors. 2, found to have an aura quickly let the patient lie flat on the bed, or lie down on a flat place nearby to prevent falls. 3.The patient’s head is tilted back excessively during the ankylosis period, and the jaw is over-opened, which may cause cervical compression fracture or dislocation of the jaw. The patient should hold the patient’s occipital area with one hand to stop the neck from overstretching, and hold the jaw with the other hand to counteract the jaw over-extension. 4, there are more respiratory secretions during a grand mal seizure, which can easily cause respiratory obstruction or aspiration pneumonia. Since the beginning of a grand mal seizure, the patient’s head should be turned to the side so that secretions can flow out naturally. In addition, it is best to unbuckle the patient’s neck to keep the airway open. The belt should also be unbuckled during seizures, and dentures should be removed when available. 5. During the clonic phase, the muscles of the limbs contract, easily causing joint dislocation and limb abrasions. At this time, you can press the large joints of the limbs (such as shoulders, elbows, hips, knees) with appropriate force to limit the amplitude of their jerking. Do not use excessive force, forceful pressure, so as not to cause artificial injury or fracture of muscles and joints. 6. After the seizure has stopped, the patient can only return to normal after a few minutes, tens of minutes or even a few hours. Some patients are in a coma during this time, so just let them sleep comfortably and quietly. Other patients are in a hazy state, the patient can appear some unconscious and purposeless impulse, destruction, aggressive behavior. Sometimes self-injury, injury, suicide, murder, destruction of objects, etc. can occur. At this time, the patient’s behavior should be strictly limited to ensure safety. 7. If the seizure lasts more than 10 minutes, or if a grand mal seizure occurs continuously within a short period of time, the patient should be sent to the hospital for emergency treatment as soon as possible.
