Vertigo in ED
Vertigo is not always labyrinthitis!! There are some potentially serious conditions to think about. Your main question should be is it peripheral [good] or central [bad]?
Methaemoglobinaemia
Q: Why are Smurf’s Blue?
A: Methaemoglobin (MetHb) of course!
– MetHb is produced by oxidisation of the Iron in Haemoglobin (Hb) from Fe2+ to Fe3+
– Fe3+ prevents Hb carrying oxygen (thus produces symptoms of hypoxia)
– Often due to chemical ingestion, but may also be genetic
– Treated with Methyl Blue & supportive measures
Hypernatraemia
Hypernatraemia is a not a common presentation in ED, as intense thirst often prevents significant hypernatraemia in neurologically intact individuals. So… Mortality rates are high (20-70%) and the severity of hypernatraemia has been shown be an independent predictor of mortality.
However, there is little good data on hypernatremia to base guidance on, and definitions vary within the literature
Retrobulbar haemorrhage
What is retrobulbar haemorrhage?
- Rapidly progressing haemorrhage into the retrobulbar space which is rare but potentially sight threatening.
- Retrobulbar haemorrhage causes a rapid rise in intraorbital volume and pressure.
- If not treated it can quickly lead to retinal ischaemia and infarction resulting in permanent visual impairment or complete visual loss.

In the young the bleeding often starts after trauma (e.g. picking or punching noses). In the elderly however, it is commonly a manifestation of underlying vascular disease. Read more
