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]?
Pulmonary Embolism – PE
PE is somehow both the most over and under diagnosed condition. with severity ranging from the questionable sub-segmental PE to the Massive PE (an indication for thrombolysis). So think:
- Does this presentation sound like a PE? – If not STOP here
- Pregnant? – Click Here
- Do you think this is likely a PE? (if so you can’t use PERC)
- Does D-Dimer answer your question? (whats the Wells)
- High-Risk (Wells >4) – Treat before CT
- Massive PE – think Thrombolysis
- Sub-Massive PE – there is lots of debate (involve seniors), locally needs 2 consultant sign off and not considered time critical.
Giant Cell Arteritis – GCA
GCA is a is a vasculitis generally seen in the over 50’s and associated with polymyalgia rheumatic (PMR). However, unlike a lot of rheumatology, GCA is far from a benign condition that can be passed back to the GP’s, it can lead to some significant problems
- Sudden irreversible visual loss
- Development of thoracic aortic aneurysm
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
Emergency PEG/PEJ/RIG replacement
When a patients with a PEG/PEJ/RIG that has come out attends the ED its important that we can either replace it or insert an EN-Plug OR NG tube into the tract to maintain patentcy while being admitted (how to guide is below)
NG/Foley catheters must not be used to administer fluid or feed nor should the patient be sent home with it in-situ.
