The recovery of a child after a burn has a lot to do with the severity of the burn, as well as the repair ability of the child’s own skin and the treatment after the injury. The skin is usually broken for burns of degree II or higher. If it is shallow degree II, the wound can heal in 1-2 weeks if there is no infection. Deep II degree, if the wound is not infected, 3-4 weeks can heal. In the case of degree III burns, healing will take more than 6-8 weeks, or even longer. The first timely treatment is very important. Cold therapy can prevent the heat from continuing to act on the trauma and deepen its scalding, and at the same time can reduce pain, exudation and edema, which is conducive to the reduction of depth and acceleration of healing after scalding. If a child is scalded, regardless of whether there is blistering or whether the skin of the blister falls off, it is recommended that adequate cold therapy be given in a timely manner, flushing with running tap water, or soaking with cold water or ice packs, which can effectively relieve the child’s pre-existing pain. At the same time, trauma treatment should be carried out in a regular hospital and appropriate biological dressings should be selected to prevent deepening of trauma and infection at a later stage and to promote healing.
