What is considered to be a secondary injury?

Secondary injury is a term applied to the destructive and self-propagating biological changes in cells and tissues that lead to their dysfunction or death over hours to weeks after the initial insult (the “primary injury”). In most contexts, the initial injury is usually mechanical.Click to see full answer. Likewise, what is the difference between a primary and secondary injury?In traumatic brain injury (TBI), primary brain injury occurs during the initial insult, and results from displacement of the physical structures of the brain. Secondary injury, which is not caused by mechanical damage, can result from the primary injury or be independent of it.Secondly, what changes occur in primary and secondary damage? Primary injury refers to the initial impact that causes the brain to be displaced within the skull. Secondary injuries gradually occur as a consequence of ongoing cellular events that cause further damage. In respect to this, what is a secondary blast injury? Injuries caused by these pressure or blast waves are described as primary, secondary, tertiary, and quaternary. Primary blast injury occurs when the blast wave hits the body. Secondary blast injury includes being hit by flying debris, which can cause both penetrating and direct impact trauma.What qualifies as a TBI?Traumatic brain injury (TBI), also known as intracranial injury, occurs when an external force injures the brain. TBI can be classified based on severity, mechanism (closed or penetrating head injury), or other features (e.g., occurring in a specific location or over a widespread area).
