Alkali burn
Common are caustic, ammonia, lime and so on. Alkali can dehydrate tissues and saponify fats. Alkali ions combine with proteins to form basic proteins, which can penetrate deep tissues. Therefore, if the early treatment is not timely, the wound can continue to expand or deepen, and cause pain, caustic burn wounds, early flushing or small blisters, which are generally deep. After the scorch or necrotic tissue falls off, the wound surface is sunken, and the edges sneak, often unhealed. The time required for rinsing with water after first-aid burns is longer, and neutralizers are generally not used.
