When someone suddenly falls to the ground with a loud scream, twitching limbs, eyes rolled up, foaming at the mouth and bruised face, what should you do as a witness? What should be done: 1. Clear the patient’s surroundings of debris, especially sharp objects that may cause injury. 2. Have the patient lie on his or her side, undo the tie, clothespin, bra and belt, remove the secretions from the mouth and nose, and keep the airway open. If possible, give oxygen. 3. Record the duration of the convulsion and the specific symptoms during the convulsion so that medical personnel can understand the condition. 4. Check the trauma of the fall. 5. You can call the emergency number. What can’t you do? 1. You can’t pinch the person by force. Pinching cannot stop a convulsion, and excessive force can lead to injury. 2. Do not stuff things into your mouth. Do not stuff anything into the patient’s mouth without the presence of professional medical personnel, because the strong force of the bite muscle during a convulsion may cause the patient to bite off the stuffed object, and the broken object may easily cause asphyxiation, leading to very serious consequences. 3. Do not let the patient lie flat on his back. 4. Do not press the patient’s limbs with force. Pressing the patient’s limbs hard during convulsions may cause fractures or sprains. 5. After the convulsions stop, the patient will have a short period of unresponsiveness and confusion, and cannot be fed water or medicine to avoid accidental aspiration.
