Describe the pathophysiology of the disease(s) your client has.

Hematoma is a swelling or mass of blood (usually clotted) confined to an organ, tissue, or space and caused by a break in a blood vessel. Subdural means beneath the dura mater (the outer membrane covering the spinal cord and brain). A subdural hematoma is located beneath the membrane covering the brain and is usually the result of head injuries or the shaking of a small child or infant. It may result in loss of consciousness, seizures, mental or physical damage, or death.

Subdural hematomas are most frequently the result of a head injury. They can occur spontaneously in the elderly, but this is less common. Traumatic subdural hematomas are among the most lethal of all head injuries.

Subdural hematomas are seen in approximately 15% of all head traumas. Tiny "bridging veins" that run between the surface of the brain and its outer covering (dura) stretch and tear, allowing blood to collect. These veins rupture because of the sudden change in velocity of the head during the trauma.

Acute, subacute, and chronic are all adjectives used to describe subdural hematomas and reflect the time course of the collection of blood. Traumatic acute subdural hematomas carry the highest risk to the patient, with a mortality rate of greater than 50% in most studies.

Risks include:

• Head injury

• Very young or very old age

• Anticoagulant medication (blood thinners)

• Chronic alcohol use
