Abstract
Traumatic brain injury remains a major cause of morbidity and
mortality particularly in young people and still has no specific
treatment
TBI may be divided into primary injury and secondary injury.
Primary injury is induced by mechanical force and occurs at the
moment of injury. Secondary injury is not mechanically induced. It
may be delayed from the moment of impact, and it may superimpose
injury on a brain already affected by a mechanical injury.
The pathology of head injury is increasingly well understood.
Mechanical forces result in shearing and compression of neuronal and
vascular tissue at the moment of impact. A series of pathology events
may then lead to further brain injury. This secondary injury may be
amenable to intervention and is worsened by secondary physiological
insults. Various risk factors for poor outcome after TBI have been
identified. Most of these are fixed at the time of injury such as age,
gender, mechanism of injury and presenting signs, but some as
hypotension and hypoxia are potential areas for medical intervention.
Modern neurocritical care management utilizes a host of
monitoring techniques to identify or predict the occurrence of
secondary insults and guide subsequent therapeutic interventions in an
attempt to minimize the resulting secondary injury. Recent data
suggest that the use of protocolized management strategies, informed.
