Randomized Controlled Trial Comparative Study Clinical Trial
Effect of backrest position on intracranial and cerebral perfusion pressures in traumatically brain-injured adults.
Backrest positioning for brain-injured adults is variable. Some data support using a flat backrest to optimize cerebral perfusion pressure; other data support elevating the head of the bed at least 30 degrees to reduce intracranial pressure. ⋯ The results strengthen the research foundation for raising the backrest position for adults, 18 to 45 years old, who have nonvascular, nonpenetrating, severe brain injuries.
