What are the differences between poisoning and accidental first aid

To be honest, an experienced nurse who has been in pre-hospital emergency care for 8 years said that the core difference between the two is that one needs to "block the poison" first, and the other needs to "stop the loss" first. Essentially, the persistence of the pathogenic factors is different, and they are two completely different treatment ideas.

Last week I just picked up an old man who was poisoned by spraying dichlorvos to kill mosquitoes at home. When his family found out, he was already slumped on the sofa. They were so panicked that they carried him out the door without even taking off his short sleeves stained with pesticides. We arrived at the first response First, the uncle was stripped clean of all his clothes, and his exposed skin was wiped with a warm towel before he was put on a stretcher. Even the sewage from the gastric lavage was specially bagged separately to avoid secondary poisoning caused by residual pesticides on the medical staff or attendants. In the past two years, the industry was still debating whether to induce vomiting immediately after accidentally taking a corrosive poison like toilet cleaning spirit. The old first aid manual also stated that vomiting should be given priority. Now more and more clinical data prove that vomiting may perforate the corroded esophagus and stomach wall. Now there is basically a consensus. Unless the person is fully conscious within 15 minutes after taking it, it is not recommended to induce vomiting on the spot, and the patient should be sent to a doctor for intubation and gastric lavage first.

Switching to ordinary accidental injuries, the idea is completely reversed. Last month, we met a worker who was hit on the shoulder and back by a falling brick at a construction site. When we arrived at the scene, the brick had already rolled to the side. There was no possibility of continuous injury. The first priority was to hold down the bleeding wound and put a cervical collar on the neck to prevent cervical vertebra displacement and damage to the spinal cord. Even checking for internal injuries was ranked after hemostasis and fixation. It is not without controversy. In the past, the industry has discussed whether open wounds should be rinsed with clean water on site. The current consensus is that it depends on the degree of contamination of the wound. If there is a lot of sediment and industrial waste, you can simply wash away the surface contaminants with clean room-temperature mineral water. If there is no obvious dirt, just use sterile gauze to pressurize the wound. The time saved is enough to make half the way to the hospital.

To give a simple metaphor, the difference between the two is like a cracked water pipe in your house and leakage: in the case of poisoning, the water valve is still open and the water flows out. Your first reaction must be to turn off the water valve first, otherwise no matter how much water you drag, it will be in vain; a common accident is that the water valve has bounced back and closed by itself, and you must quickly clean up the water flowing to the sockets and electrical appliances first, so as not to cause a more serious short circuit or fire.

Many people don’t understand this and it’s easy to get into trouble. For example, when someone is poisoned by carbon monoxide in winter, they pinch the person and feed them sugar water, forgetting to open the window immediately to ventilate the source of the poison, which wastes the best time to deal with it; there are also people who are stung by poisonous snakes and venomous bees, treating them as ordinary scratches, squeezing the wound and applying hot compress, which in turn accelerates the spread of toxins in the body and worsens the injury.

In fact, after traveling to the scene for a long time, there is no need to memorize the different terms. When you go to the scene, you will know at a glance: the thing that caused the harm is still causing harm to people. If you know this clearly, you will basically not make a big mistake.
