Doubt in the play: Can mild burns be painted with purple potion?
Doctor's interpretation: generally speaking, purple liquid medicine is not recommended for trauma, because it will stain the skin and cover the original injured area, and it is impossible to accurately judge the scope and area of the wound, which may affect the doctor's understanding of the depth of burn, which may affect the treatment. However, it is correct that mild burns do not need dressing change, and mild burns need exposure therapy. In addition, applying mercuric chloride and soy sauce to burn wounds is a common "soil cutting", which will also cover up the illness.
Many people use toothpaste after scalding, thinking that toothpaste plays a cool and heat-dissipating role. There are actually some hidden dangers. Because toothpaste itself has no anti-infection effect, it often carries a certain amount of bacteria. The friction agent in toothpaste is irritating to the wound, while the foaming agent and flavoring agent have no therapeutic effect on the wound, which is easy to cause granulation proliferation and wound infection.
For mild burns, the correct treatment method should be to immediately soak the injured part in cold water for "cooling treatment", and immediately wash the injured part with running water. If it is inconvenient to clean the part, you can also apply it with a cold towel to take away the heat and reduce the degree of burns.
Doubt in the play: Can the blister be gently bandaged with vaseline gauze?
The doctor explained: if burns cause blisters, don't break the small ones until they are naturally absorbed and dissipated; The older one needs to go to the hospital for treatment, so it is not recommended to choose by yourself. So as not to affect wound repair and increase the chance of infection. Generally, if the blister is broken, the professional doctor will cover it with vaseline gauze inside and clean gauze outside.
Some people think that cold water will blister after scalding. In fact, the absence of blisters has nothing to do with contact with cold water, but only with the cause and depth of burns. Rinsing with cold water immediately after burn for a period of time can make the blood vessels of the wound contract, reduce the exudation of tissue fluid and reduce the formation of blisters.
Doubt in the play: drink plenty of boiled water after scalding. Can I take painkillers if it really hurts?
Doctor's interpretation: Some people think that after burns, patients are thirsty and lose a lot of body fluids, so they should drink plenty of boiled water to replenish water. But this is not the case. Drinking plenty of water will dilute the electrolyte in the blood, leading to water poisoning. The correct method should be to supplement an appropriate amount of water containing electrolytes, such as brackish water.
Moreover, painkillers should not be taken by yourself, but should be taken under the advice of a doctor. Because there are many precautions for taking painkillers, sometimes taking painkillers will cover up the illness.
Doubts in the play: mild burns can be wrapped with moist gauze, and severe burns can be covered with clean dressings?
Doctor's interpretation: In the early stage of burns and scalds, we should focus on controlling infection and reducing the chance of infection. Moist therapy can be used later. If the burn area is relatively large, it is recommended not to wrap any gauze, so it is difficult for ordinary families to find a suitable dressing. You should go to a big hospital with rich experience in burns and scalds as soon as possible. Because burn patients will have shock stage soon, anti-shock treatment is very important at this time.
Tip: There are skills in self-rescue of burns.
In daily life, in the face of burns, how should we give ourselves first aid? The doctor of medicine gives you some advice. When burned by fire, you should take off your burning clothes immediately. Avoid running and shouting with fire, so as not to inhale harmful gases and avoid respiratory tract burns. Cover your nose and mouth with a wet towel to prevent suffocation or poisoning caused by inhalation of smoke. Lower your body against the wall to find the exit.
For the most common mild burns, especially the limb burns caused by life factors, most of them are red and have a burning sensation, just like the feeling of scalding. At this time, the affected limb should be immediately washed with clear water or soaked in cold water for about 30 minutes to cool the wound and reduce the degree of thermal damage.
Don't take off your clothes in a hurry for burns covered by clothes, because clothes (especially chemical fibers) are easy to stick to the skin after burning, and will be torn off once they are forced. Cold water should be poured on the clothes immediately, and after the local temperature drops, it should be gently taken off or cut longitudinally with scissors.
