The use of Optic Nerve Shaeth Diameter measurement for assessment of patients with potentially raised ICP has been a contentious area of practice for a few years.
The studies look good at first read, but then when you stand back and look at them all - something is wrong - they all disagree on the norms, the cut-offs and the anatomy.
So I have enlisted the help of Dr LEanne Hartnett - US-wielding ED Physician from Fremantle Hospital in WA.
Leanne helps us sort out the facts and form an idea of where we need to go to make this potentially beautiful use of US really work on the floor.
