When a patient has a sudden convulsion, the family should first place the patient on the ground and clear the surrounding objects that may damage the patient, such as stones or wooden blocks. When the patient is convulsing, the family should not press the patient hard, as this may damage the patient. If the patient is clenching his or her teeth, the patient’s family should put a small towel or other object in the patient’s mouth, paying attention to leaving a certain gap to avoid breathing difficulties. If the patient wants to vomit, the patient should be kept on his or her side to prevent vomit from being inhaled into the patient’s lungs and endangering the patient’s life. The other thing that the family should do is that they should call 120 in time to seek help from medical personnel and need to pay close attention to the patient’s condition so that they can later communicate with the patient’s doctor, which can play a supporting role in the patient’s diagnosis.
