The best way to protect the tongue is to put a gauze tongue depressor between the patient’s upper and lower molars (teeth) to prevent the patient from biting his or her tongue during the clonic phase. It should not be put on during the aura period, but should be put on during the tonic period when the patient opens his mouth, and should not be put on during the clonic period. Pressing the tongue can also prevent the tongue from falling back and blocking the airway. 2, when found to have an aura quickly let the patient lie flat on the bed, or lie down on a flat place nearby. If it is too late to make the above arrangements, when the patient is found to fall, you should quickly hold the patient and let him fall down. In order to prevent their own sudden fall to the ground and fall head or body injury. 3, the patient ankylosis period more head back, jaw over-open, can cause cervical compression fracture, or dislocation of the jaw. In this case, one hand should hold the patient’s occipital area with slight force to stop the neck from over-extending, and one hand should hold the jaw 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 unbutton the patient’s neck to keep the airway open. 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 shoulder, elbow, hip and knee) with appropriate force to limit their twitching amplitude. At this time, do not use excessive force and forceful pressure, so as not to cause artificial injury or fracture of muscles and joints. 6, the seizure will also be unbuckled their belt, with dentures should be removed. 7, after the grand mal convulsions stop, the patient has to pass a few minutes, tens of minutes or even a few hours to return to normal. During this time some patients are in a drowsy state, just let them sleep comfortably and quietly. Other patients are in a hazy state, the patient can appear some unconscious and purposeless impulses, destruction, aggressive behavior. Sometimes self-injury, injury, suicide, murder, destruction of objects, etc. can occur. At this time, in addition to immediately giving the patient intramuscular or intravenous sedatives such as luminal or valium, the patient’s behavior should be strictly limited to ensure safety. In addition, it is important to mention that many patients’ family members often pinch the patient’s “human middle” point when they have a grand mal seizure, trying to stop the seizure as soon as possible, and sometimes even pinch the blood, the seizure still does not stop. We believe that seizures are caused by abnormal brain discharges, for a grand mal seizure has begun, there is no way to make it stop, only the end of brain discharges, the seizure will stop. Sometimes the seizure stops when you pinch the person for a while, but it also happens that the seizure discharges end and the seizure stops. Therefore, we hope that family members and friends, in case of grand mal seizures, in addition to taking the above-mentioned measures to protect the patient’s safety, do not do anything meaningless and detrimental to the patient’s health.
