After an accident, there is usually no opportunity for resuscitation at the scene under the guidance of medical personnel, and it mainly depends on the public to save themselves and each other, therefore, it is very important to improve people’s ability to save themselves and each other. Prof. Chai Jiake said that in daily life, thermal burns are the most common, accounting for about 85%-90% of all causes of burns. The most basic requirements for first aid at the scene of thermal burns are, first of all, to quickly get away from the heat source, take off burning clothes or douse the body with water to extinguish the fire. You can roll on the ground, rely on the body to extinguish the fire or by the help of others, with the side of the material is not easy to burn to fight, or with quilts, blankets, coats and other cover to isolate the air to extinguish the fire. Do not run and shout, because running will produce wind, wind help the fire, fire with the wind power, will make the fire more and more burning. At the same time shouting will be flame and smoke inhalation respiratory tract, aggravate inhalation injury. If it is difficult to get out of the scene, you can use a wet towel to cover your mouth to prevent the inhalation of toxic gases, pay attention to keep the body in a low position, and try to get close to doors and windows that can breathe air. For small-scale localized burns, you can use tap water to rinse or well water immersion, under the premise of tolerable, the lower the temperature of the water, the better. On the one hand, it can rapidly cool down the temperature, reduce the heat conduction to the deeper layers of the tissue and reduce the depth of the burn, and on the other hand, it can clean the wound and reduce the pain. Do not apply colored drugs such as red mercury and purple potion to the burn wound, so as not to affect the observation and judgment of the depth of the burn, and do not apply oily substances such as toothpaste and ointment to the burn wound, in order to reduce the chances of contamination of the wound and to increase the difficulty of treatment at the time of seeking medical treatment. If blisters appear, be careful to keep them, do not tear off the skin of the blisters, and at the same time use clean towels, sheets and other wraps to avoid contamination on the way to the hospital. Prof. Chai said, for critical burns patients, in principle, should be local treatment. Because of the high incidence of shock in critically burned patients, the time of occurrence is also early, some patients in two hours after the injury will occur shock. If there is no resuscitation rehydration on the hasty long-distance transfer, due to the bumps, coupled with untimely treatment on the way, will make the injury worse, aggravate the shock. Some may die on the way, and some will be sent to the hospital due to prolonged shock, severe ischemia and hypoxia, outbreaks of systemic infections, triggering a variety of visceral complications, and even multi-organ failure leading to death. For thirsty patients, you can take liquids containing salt orally in small amounts and many times, and do not take a large amount of plain water in a short period of time, so as not to cause complications such as cerebral edema and pulmonary edema.
