After a child is burned, the medication is changed to reduce the inflammation of the wound and to avoid deepening the skin damage. But changing the medicine is a very painful thing for the child. For parents, it is a heartbreaking experience. In foreign countries, medications are often changed under general anesthesia. Parents in China are more resistant to this general anesthesia. The practice is as follows: 1, first aid: rinse with cool water for 20 minutes can reduce tissue damage. 2, the child burns area of 5% or less, not including the hand or face can not need to be hospitalized. 3.The first time to clear the wound can be used muscle or oral painkillers. 4.Clear the wound: first put a few drops of local anesthetic on the burn wound, disinfect with diluted iodophor, and cut off the upper skin of the broken blister. 5, the traditional excipient is an antibacterial containing silver sulfadiazine (Silver sulfadiazine). This ointment, may cause local irritation, rash, fever, serum sickness-like reactions and other allergic reactions. There is also the possibility of partial absorption, thrombocytopenia, anemia, nausea, vomiting and diarrhea. The most important thing is that the child suffers from the need for frequent drug changes. There are many kinds of excipients of the new generation, all of which contain silver ions and have strong absorption properties. Silver ions are sterilizing, but they are not excessively absorbed by the body. The excipients absorb the wound secretions at the same time. The biggest benefit for children, parents and doctors is that the excipients can be left on the wound for a week or two. The epithelium of a typical second-degree burn heals almost completely in two weeks. This means that the child does not have to change the dressing repeatedly.
