Causes of secondary brain injury include haematoma, contusion, diffuse brain swelling, systemic shock and intracranial infection. The modern management of severe TBI has fallen into the domain of a multidisciplinary team led by neurointensivists, neuroanaesthetists, and neurosurgeons and is based on the avoidance of secondary injury, maintenance of cerebral perfusion pressure (CPP), and optimization of cerebral oxygenation.

Chronic subdural hematoma is a common treatable cause of dementia The head trauma may also cause associated brain hematomas or contusions, subarachnoid hemorrhage, and diffuse axonal injury. Traumatic brain injury (TBI) is the leading cause of death and disability in young adults in the developed world. Proper prevention of these factors may limit undesirable outcomes. Secondary injury may occur hours or even days after the inciting traumatic event. The associated neurologic and vascular damage triggers a chain of events that lead to a secondary brain injury (SBI), a preventable cause of adverse neurological outcomes. The current classification of brain oedema relates to the structural damage or water and osmotic imbalance induced by the primary or secondary injury.

But many people who die as a result of brain injury do not do so immediately. Nevertheless, it is known that the severity of the primary injury, in large part, determines a given patient’s neurologic grade on admission and conse-quently is the strongest prognostic indicator. Includes: Ischemia from hypoxia and hypotension Secondary hemorrhage and; Cerebral edema. The clinician’s role, therefore, is to recognize and document the primary brain damage, then to prevent and treat secondary brain damage. Secondary injury can occur minutes, hours, days or even weeks after the initial injury and the damage can be averted or lessened by appropriate clinical management. Mechanism of secondary brain injury In head injuries, primary damage occurs at the time of impact and includes contusions, lacerations and diffuse axonal injury. In contrast, secondary brain injury describes the damage caused following trauma due to complicating processes. Although the skull is often fractured in the process, acute cerebral damage can occur even if the skull remains intact. Looks like you’ve clipped this slide to already. ..There, that's all better.

Decreases in CBF are the result of local edema, hemorrhage, or increased intracranial pressure (ICP). Secondary injury, which is not caused by mechanical damage, can result from the primary injury or be independent of it. These events, include alterations in cerebral blood flow and the pressure within the skull, can contribute substantially to the damage from the initial injury and can be more troubling and harmful than initial injury. !O GCS of 13 may not be so “mild”O SC Stein, J Trauma.
