Experts have a certain reason
Recently, there have been frequent incidents of drowning, and Weibo has begun to pass a "running water law" on the Weibo, that is, to catch the child's feet and backs back and forth. Some of the "running water" pictures and videos have caused widespread discussion. In this regard, Zhang Weixin, deputy director of the emergency department of the People's Hospital of Jiangxi Province, pointed out that the "running water" method has a certain degree of scientificity.
Drowning water emergency method
The reporter saw on a news website on the 18th that in early June, villagers from a town in Dongguan rescued two children in Weishui from the river. The children did not breathe, and the villagers took their children’s feet and backs Child running. A few minutes later, the little boy spits a few mouthfuls of water and wows a cry. After another ten minutes, the little girl gradually resumed consciousness. There are pictures below. This post is widely spread.
The reporter found that there are many kinds of “earth methods†for the first-aid drowning in civilians. For example, there is a “riding method†in which the drowning children are placed on their shoulders and the abdomen is facing down, and then they run back and forth, or put the abdomen of the drowning child. On the knees, then beat the children's back and so on.
Experts: There is a certain truth
Are these "local methods" scientific? The reporter interviewed Zhang Weixin, deputy director of the Emergency Department of Jiangxi Provincial People's Hospital, and Zhang Weixin, who said that the "earth method" principle of these first aid drownings is the same, that is, to allow the drowning children to use gravity or squeeze the chest and abdomen in the bumpy process. Remove water that has inhaled into the lungs and stomach, as well as foreign bodies in the mouth and trachea. Most of the drowning incidents occur at unattended locations. These methods can also be used for rescue when the professional ambulance personnel are difficult to reach. effect.
At the same time, Zhang Weixin also said that from the perspective of modern medicine, these methods are easy to cause harm to the human body. First of all, some of the water that is inhaled into the lungs and the alveoli is incompetent, and bumping the drowning child backwards and forwards may cause lung damage, cause alveolar edema, and lead to hypoxia. At the same time, the bumping process can easily cause trauma.
Therefore, he suggested that in the event of a child drowning, if the 120 emergency medical staff cannot catch it at all, the on-site staff will use the CPR first-aid method in modern medicine to remove the drowning person's mouth immediately after they first rescue the child. Swelling and debris in the nasal cavity, good time in 10 seconds, and then vomiting first aid, should find a harder place, put the back of the drowning up, chest and lung compressions, so that drowning spit out the mouth, In the respiratory tract and lungs, artificial respiration is taken at the same time. After the emergency personnel arrives, the professional will perform mask oxygen supply or endotracheal intubation for oxygen.
