A fluid of 0.45% sodium chloride is a hypotonic solution,and hypotonic solutions cause cells to swell,which can cause increased intracranial pressure.This can be life-threatening for a patient with a traumatic brain injury.The other solutions are physiologically isotonic sodium-containing solutions that expand ECV but do not cause cell swelling.In the fluid container,dextrose 5% in 0.9% sodium chloride is hypertonic,but the dextrose enters cells rapidly,leaving isotonic 0.9% sodium chloride.
