What is chemical burn
summary
We had chemistry class yesterday. We were doing experiments. At that time, the teacher told us the main points, but I was naughty and didn't listen. As a result, I had an accident and burned myself. At that time, a large piece of skin on my hand was red. I went to the hospital to diagnose chemical burns. Today, let me tell you what chemical burns are.
What is chemical burn
First, the damage degree of chemical burn is closely related to the nature, dose, concentration, physical state (solid, liquid, gas), contact time and contact area of chemicals, as well as the emergency measures at that time. The damage of chemical substances to the local area is mainly cell dehydration and protein denaturation, and some heat production aggravates the burn.
Second, chemical corneal burns can be divided into acid burns and alkaline burns. Acid substances have coagulation effect on protein. After protein denaturation and coagulation, it effectively prevents the remaining acid from penetrating into the deep layer. Therefore, the degree of damage to the cornea is often greener than that of alkaline substances.
Third: alkali burns, because alkali can dissolve fat and protein, can quickly penetrate into the deep tissue and eye after contact with tissue, and the damage to eye tissue is persistent, which is easy to cause complications such as anterior iris synechia.
matters needing attention
In case of severe burn, we need to take simple treatment and send it to the hospital for professional treatment in time. The doctor will clean, disinfect and bandage the wound, so as to effectively avoid infection. We can't bandage the wound by ourselves, otherwise it will be infected.
