When a baby is burned, parents are most concerned about scarring in the future. However, deeper wounds, such as those of degree II or higher, or infections of the wound during treatment (which will deepen the wound) will inevitably leave scarring. After healing, if the local skin is red, swollen, higher than the skin surface, painful and itchy, these are all manifestations of post-burn scar growth, which can be used if it has not yet affected the functional impairment of the baby’s limbs as follows: First, use topical products to control the pain and itch, and at the same time, inhibit scar growth and promote scar maturation. For example, silicone diaphragms can be applied externally or silicone gel can be applied externally, as well as drugs such as Conrad and Xylitol. Compression can also be applied with an elastic sleeve or elastic bandage. This type of scar takes a long time to mature, ranging from 2-3 years for short cases to more than 10 years for long cases. As long as the scar does not cause dysfunction, it is perfectly acceptable to wait until the scar is stable before undergoing plastic surgery. The criteria for a stable scar are: no pain, flattening, whitening, and softening. When the child is more than 10 years old, preferably after 16 years old, plastic surgery can be performed according to the situation at that time. If the scar is still above the skin surface and the area is large, dilator flap repair surgery can be performed. If the area is smaller, excision and suturing or local flap transfer can be performed. If the scar is flat, non-surgical treatment such as laser can be used directly to fade the scar, but not to eliminate it completely. If the proliferation of any stage of the scar causes dysfunction of the baby’s limbs or five senses, the baby must be seen by the hospital’s plastic surgery department as soon as possible to solve the functional problems early.
