Timely first aid for burns can reduce the depth of burns, minimize the occurrence of comorbidities, and reduce mortality. First aid should reflect a “fast” word, as the saying goes, fire and water have no mercy. The principle of first aid: the key is to quickly exclude injury-causing factors, so that the patient out of the scene, placed in a safe place. Do not rush the patient to the hospital, medical personnel at this time to remain calm, awake, for the patient’s life-threatening injuries, such as hemorrhage, bone fracture, asphyxia, trauma, acute poisoning, etc., should be given the necessary first aid treatment. Intravenous channels should be established as soon as possible, and rehydration therapy should be given to avoid excessive drinking to avoid vomiting, especially drinking plain water alone will lead to water intoxication. Oral saline or burn drinks should be given in moderation. The wound can be treated without special treatment to avoid re-injury or contamination, especially note that colored topical medicines are forbidden to be applied on the wound.
