The principles of treatment of chemical burns, like general burns, should be quickly removed from the scene, terminate the continued damage to the organism by chemical substances, take effective detoxification measures to prevent poisoning, and conduct a full physical examination and chemical testing. First of all, you should immediately get away from the scene, take off the clothes impregnated with chemical substances and immediately rinse with a lot of water. The purpose is firstly to dilute and secondly to mechanically rinse the chemical substance from the trauma and mucous membrane. A certain amount of heat may be generated during rinsing, but the heat gradually dissipates due to continuous rinsing. The water used for flushing should be more and long enough. The duration of the rinse is generally required to be more than two hours, especially in the case of alkali burns where the rinse time is too short to be effective. If there are flame burns at the same time, flushing still has the effect of cold therapy. Head and facial burns should pay attention to the eyes, nose, ears, oral cleaning, especially the eyes, should first rinse, the action should be gentle, if the conditions available isotonic saline rinse, otherwise, general water can also be. If eyelid spasm, lacrimation, conjunctival congestion, corneal epithelial damage, and cloudiness in front is found, it should be immediately flushed with saline or distilled water for more than half an hour. Then alkali burns are flushed with 3% boric acid solution again, and acid burns are flushed with 2% sodium bicarbonate and then stained with 2% fluorescein to check for corneal damage. To prevent iridocyclitis, drops of 1% atropine, dilated pupil three to four times a day, 0.25% chloramphenicol solution, 1% gentamicin, or 1% polymyxin solution can be used for eye drops. In the case of lime burns, the lime should be removed before cleaning to avoid lime heating up when exposed to water and aggravating the traumatic injury. Continuous flushing with plenty of running water is more effective than antagonizing with neutralizing agents alone. The time with neutralizing agent should not be too long, usually 20 minutes is enough, and still need to rinse with water again after neutralizing treatment to avoid further damage to the organism because of heat generated by neutralizing reaction.
