Bruising from car accidents can occur due to several reasons, including:
- Airbag deployment: Airbags are designed to save lives. However, the force of deployment can cause airbag bruises and contusions.
- Seat belt use: Seat belts are crucial for preventing more severe injuries. However, the force exerted by a seat belt can lead to abdominal bruising after a car accident.
- Steering wheel impact: Contact with the steering wheel during a frontal collision can lead to bruising on the face, head, or chest.
Types of bruising from car accidents: Contusions and Hematomas
Contusions are the most common type of bruise. They occur when tiny blood vessels (capillaries) beneath the skin break, leading to visible discoloration. Contusions can be mild or severe, and the severity of the injury is often reflected in the size and color of the bruise.
Hematomas, on the other hand, are a more severe form of bruising. They result from the collection of blood outside of blood vessels and can be classified into two primary types:
- Subcutaneous hematoma: These hematomas occur beneath the skin, usually appearing as raised, painful, and swollen areas. They can occur after car accidents and may be associated with seat belt injuries.
- Subdural hematoma: These are more critical and occur when blood collects between the brain and the dura mater (a protective layer around the brain). Subdural hematomas can be life-threatening and require immediate medical attention.
