When does Primary become Secondary Injury?

On scene ED NCCU

Secondary brain injury occurs after the primary mechanisms of injury have run their course (Gennarelli & Graham, 2005)

Secondary brain injuries often result from complications of the primary mechanism of injury and may occur anywhere from hours to days after the initial injury (Dawodu, 2007)

So at best

Neurocritical Care will only save neurons that have not died

NCCU Has 3 functions

Maintain Airway Good Nursing Care Weaning from Ventilator

The Time to Save neurons is BEFORE Neurocritical care

Once there… In the spontaneously breathing patient…
