First aid for patients with syncope includes general first aid measures and first aid measures for the primary disease. General first aid measures can be performed first according to the specific situation, and subsequent first aid can be performed by a professional doctor for the cause of syncope. When a patient is found to have prodromal symptoms of syncope or loss of consciousness, call 120 immediately and ask for the help of medical personnel. At the same time, the patient should be immediately placed in a flat position with legs elevated to allow blood to flow back to the brain as much as possible and increase cerebral perfusion to achieve the effect of improving the syncope state and avoiding brain hypoxia. In addition, the patient should be immediately unfastened from tight clothing or other restraint items, and the head or body should be turned to the side to prevent the tongue from falling down into the throat and blocking the airway, causing respiratory impairment, and also to avoid inhalation of vomit when nausea and vomiting occur. Do not feed anything through the mouth until the patient’s consciousness is restored, do not stand up until physical strength is restored, and assist and observe for a few minutes after standing up to prevent falls. After the patient is conscious, ask if there is any primary disease and find the cause of the syncope. For example, if syncope occurs suddenly in the elderly, consider whether there is internal hemorrhage, heart attack, etc. These conditions can cause heart block and arrhythmia, which can lead to syncope. Adolescents consider possible causes of syncope such as heat in the surroundings, hunger, fatigue, alcohol intoxication, or emotional excitement. If the patient has postural hypotension, be careful to stand up slowly when standing. For syncope with carotid sinus allergy, try not to wear tops with very tight collars and try to turn the body together when turning the head instead of turning the head alone. The above is the first aid method for patients with syncope, first of all to avoid life-threatening emergencies and at the same time to avoid further damage caused by syncope, and then to be further treated by medical professionals according to the causes of syncope for corresponding first aid.
