Scalp lacerations can be caused by sharp or blunt objects, resulting in the rupture of scalp tissue. The depth and shape of the injury vary, often accompanied by significant bleeding, which may lead to shock. It is one of the more common types of craniocerebral injuries. Wounds caused by sharp objects have neat edges, while those caused by blunt objects have irregular edges, appearing as straight or jagged lacerations. The scalp has a rich blood supply, giving it strong wound healing and infection resistance capabilities. Generally, these injuries can heal with proper treatment.

1. Fresh lacerations often bleed profusely in a short time, and may even lead to shock. 2. The scalp tissue is partially or completely severed, with varying depths and extents, and the wound edges may be neat or irregular. 3. The injured area is swollen.

bubble_chart Diagnosis

1. History of sharp or blunt trauma to the head. 2. Local swelling and bleeding at the injury site. 3. Partial or complete laceration of the scalp tissue. 4. Foreign objects such as hair, hat fragments, or mud may be present in the wound.

bubble_chart Treatment Measures

1. Cleaning and disinfection of head trauma. 2. Debridement and suturing of the wound to repair the injury. 3. Infection prevention treatment. Expert Tip: Scalp lacerations are often caused by sharp or blunt objects directly impacting the head. Therefore, care should be taken in daily work and production to avoid foreign objects hitting the head and causing scalp lacerations. In the event of a scalp laceration, emergency measures include applying pressure with clean gauze to stop bleeding—avoid stuffing the wound with foreign objects—and keeping the wound clean. Seek debridement and suturing at a nearby clinic or hospital.

1. Cured: Scalp healed, swelling subsided, no infection. 2. Improved: Partial scalp healing or accompanied by swelling. 3. Not cured: Scalp not healed, infection, symptoms worsened.
