Because the blood supply to the soft tissues of the skin of the head is very rich, after head trauma, there may be swelling of the soft tissues of the skin or subcutaneous hematoma, so the head will be covered after trauma. To eliminate swelling, cold compresses can be applied to the traumatized area at an early stage. Ice can be wrapped in a towel and applied to the traumatized area to reduce the inflammatory exudation from the injured area, which can eliminate swelling and relieve pain. After more than 24 hours of trauma, local heat can be applied to the traumatized area to promote blood circulation and eliminate swelling. In addition, you can apply topical medications such as Yunnan Baiyao aerosol, which has the effect of activating blood circulation and resolving blood stasis, and you can also take oral Chinese medicine that has the effect of activating blood circulation and resolving blood stasis, such as Panax notoginseng injury tablets. If the pain in the injured area is obvious, you can take oral anti-inflammatory and analgesic drugs, such as diclofenac sodium, which can relieve pain and eliminate swelling. If the patient has headache, dizziness, nausea, vomiting, and blurred vision, he or she should go to the hospital for examination in time to exclude intracranial hematoma and other conditions.
