EPIDURAL HEMORRHAGE Meaning and
Definition
-
Epidural hemorrhage, also known as an extradural hemorrhage, is a medical condition characterized by bleeding between the dura mater (the outermost protective layer of the brain) and the skull. This condition occurs as a result of trauma or injury to the head, particularly when there is a fracture or rupture of the middle meningeal artery or vein.
Epidural hemorrhage is a potentially life-threatening condition that can lead to severe complications if not promptly diagnosed and treated. The bleeding typically occurs due to the rupture of blood vessels within the epidural space, leading to the accumulation of blood that puts pressure on the brain and surrounding structures.
Symptoms of epidural hemorrhage usually develop rapidly and include a brief loss of consciousness following the initial head injury, followed by a lucid interval in which the person may seem fine. However, as the bleeding progresses and the blood continues to accumulate, symptoms may worsen and include severe headaches, nausea, vomiting, seizures, drowsiness, confusion, and ultimately, loss of consciousness.
Immediate medical intervention is crucial to prevent potential complications such as brain damage, coma, or death. Treatment generally involves surgical intervention to remove the accumulated blood and repair the damaged blood vessels. Additionally, supportive care, including pain management and monitoring the intracranial pressure, may be necessary during the recovery period.

Etymology of EPIDURAL HEMORRHAGE
The word "epidural" originates from the Greek roots "epi-" meaning "above" or "upon", and "dura" meaning "hard". In medical terminology, "dura" specifically refers to the dura mater, which is the tough outermost membrane surrounding the brain and spinal cord. Therefore, "epidural" denotes something occurring on or above the dura mater.
"Hemorrhage", on the other hand, is derived from the Greek words "haima" meaning "blood" and "rhēgnȳmi" meaning "a bursting". Consequently, "hemorrhage" refers to the abnormal and excessive bleeding that occurs due to the rupture or bursting of blood vessels.
