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

Early Pregnancy Bleed <16/40

Bleeding in early pregnancy is a relatively common problem and in the many cases (esp. with spotting) the pregnancy remains viable. However, bleeding in early pregnancy should never be thought of as normal, and it is vital that we investigate this appropriately.

 

Communication is also vital at a very stressful time

  • Who you are discussing this pregnancy in front of? – Does the patient want them to know
  • Manage expectations – There is nothing we or mum can do to change the out come of the pregnancy apart from ensuring mum is well
  • Ensure the patient has all the details they need – Return advice, clinic time, where to go, what is happening
  • Be sensitive to the patients feelings – Patients respond very differently, be careful not to impose your emotions/assumptions on the situation

Think Anti-D!

There are numerous causes of headache, however, the pressing question in the ED is,

Is this a primary or SECONDARY headache?

  • Primary headaches [e.g. tension & migraine}, maybe painful and need analgesia but don’t require emergency investigation.
  • Secondary headaches, often but not always have serious underlying causes [e.g. SAH, central venous thrombosis] requiring emergent investigation and treatment
