There is generally no quick fix for a bruise. If a child has a bruise, it can be removed by applying ice packs, heat packs, or medication that activates blood circulation and removes blood stasis (promotes blood flow and eliminates bruising). 1. Ice: If a child’s bruise occurs within 24 hours, you can help eliminate the bruise by applying ice. By applying ice to the bruised area, it can help to reduce the exudation of tissue fluid, which can improve the situation of subcutaneous bruising, so as to achieve the purpose of eliminating the bruise, and ice can also help to reduce swelling and relieve pain (eliminate swelling and pain). 2. Hot compresses: if the child bruises bruises for more than 24 hours, and the bruised area has no obvious trauma, can be eliminated by hot compresses, hot towels can be applied to the bruised area, which helps to improve local blood flow and metabolism, to avoid the accumulation of bruises, to help eliminate the bruises. 3. The use of blood circulation drugs: such as safflower oil, pain plaster, etc., take the appropriate amount of drugs coated in the palm for friction, and then the palm covered in the bruised area gently massage, can play the role of blood circulation, thus helping to eliminate the bruises. If the bruise is mild, parents can follow the doctor’s instructions to deal with it themselves, but if the bruise is serious or does not dissipate, it is recommended that the patient go to the hospital, under the guidance of the doctor for treatment.
