What is the difference and connection between poisoning and accidental first aid

The core difference is the difference in treatment priorities caused by different sources of injury, while the underlying logic is completely unified, all aimed at minimizing injuries and saving lives before professional medical resources arrive.

I have been running pre-hospital first aid for almost 8 years, and I have encountered too many situations where ordinary people confuse the logic of the two types of first aid. The one that impressed me most was a scene last summer: someone vomited and had diarrhea after eating spoiled braised vegetables. His companion thought it was an "accident". According to the trauma first aid procedures learned online, he had to lay the person down and not move, which delayed the best time to induce vomiting. By the time he arrived at the hospital, he was already suffering from dehydration symptoms. Ordinary accidental injuries, whether they are bumps, falls, burns or car accidents, are caused by external force or the direct action of external energy. The treatment logic is to "block" first - block the bleeding, fix the injured part to avoid secondary injuries, and try not to change the patient's physical condition unless there is immediate life danger; poisoning is when toxic substances enter the body If damage continues to occur, the logic of treatment is to "eliminate" first - inducing vomiting, washing the skin, retaining samples of suspected poisons, and removing the poisons that have not yet been absorbed to avoid further damage. To use an inappropriate analogy, the former is like plugging holes in a leaking house first, while the latter is like cleaning out dangerous goods at home first. The ideas are completely different.

Oh, by the way, there is still some debate in the industry about the priority of handling patients with unexplained coma. Most first responders who have been on the front line all year round advocate following the ordinary accident process, first assessing the heartbeat, breathing, and opening the airway. After all, if they are dead, there is no need to discuss other matters. However, doctors who specialize in poisoning will recommend that the patient's vomitus, empty bottles around him, and even remaining food samples be collected as soon as possible. Otherwise, when they are sent to the hospital, they will not know what kind of poison they have been exposed to, and even special antidotes will not be available. Both theories are supported by clinical data. The latest pre-hospital standards now make a compromise. When arriving at the scene, take 10 seconds to scan the surrounding environment. If there are obvious clues of poisoning such as collective illness, empty pesticide/drug bottles, and special odors, the samples should be collected first, and then the vital signs should be stabilized according to the routine process.

But having said that, the two are not completely separated. They are often intertwined when it comes to complex scenes. I was on duty in an accident in a chemical industry park last month. The worker was scratched on the leg by the explosive debris and also inhaled the leaked toxic gas. At this time, you can't just bandage and stop the bleeding and ignore the poisoning, nor can you just induce vomiting and detoxification and let the wound break out. Blood, the first thing to do is to move the person to a safe upwind area, confirm that breathing is smooth, and perform cardiopulmonary resuscitation immediately if the heart stops. These underlying principles of "saving life first, treating injuries later" are completely common, including details such as why comatose patients should not be fed water, and if they are vomiting, they should turn their heads to one side to prevent choking. The requirements in the two first aid systems are exactly the same.

In fact, ordinary people don’t have to worry too much about how to distinguish between the two. If you encounter an incident, call 120 as soon as possible and explain clearly the situation at the scene, such as whether you fell, whether you ate anything special, and whether anyone else around you has the same symptoms. The operator will teach you step by step the safest preliminary treatment, which is much more reliable than trying to classify by yourself.
