If the wound is small, you can disinfect the wound yourself with iodine or alcohol. If the wound is caused by contamination, you need to go to the hospital for tetanus. If the wound is large, you need to go to the hospital for debridement treatment, because debridement can keep the wound sterile and make it more conducive to recovery. If you do not go to the hospital for treatment, it may lead to localized infection or even necrosis. However, for all patients with head trauma, in addition to the need to pay attention to simple scalp injuries, it is also necessary to pay attention to changes in the patient’s condition. If the patient develops dizziness, headache, vomiting and other symptoms after the injury, it is mostly considered to be caused by concussion. If there is agitation and impaired consciousness, it needs to be taken seriously and the possibility of combined intracranial hemorrhage should be considered.
