If a scalp laceration is relatively minor, it is usually treated without leaving any after-effects. However, if the scalp laceration is more extensive, deep and serious, scar tissue may be formed, which may affect the appearance. If the treatment is not timely, there may also be infections caused by scalp trauma, and scalp lacerations are not treated in a timely manner, causing ischemic shock resulting from hemorrhage and then coma, these problems are more serious. If infection is caused after scalp laceration, it is not only a localized infection situation. Because of the large amount of bleeding in the head, if the infection is more serious and not treated in time, it can also cause systemic sepsis and bacteremia, which can even affect the life of the patient.
