  1. Describe and Interpret:

Normal anion gap metabolic acidosis

HCO3 14, BE -4

A Gap 10

Severe hypoglycaemia

Severe hyponatraemia

moderate hyperkalaemia

4 features of a typical Addisonian Crises

Severe renal failure

  1. Features of Addison’s Crises:

– Darkening of scars

In this patient is the sepsis secondary to the Addison’s or could he have meningococcal septicaemia with Adrenal haemorrhage (waterhouse-Friedrichsen)

  1. Immediate life threats:

Severe hypoglycaemia

Shock

Sepsis

hyperkalaemia

Cortisol deficiency

  1. Treatment:

Correct hypoglycaemia – 50mls 50% dextrose

Fluid rehydration – 0.9% Saline

Antibiotics – broad spectrum cover with CNS peneration (PLEASE NOTE: Vitamen T ie. Tazocin/Timentin may have poor CNS penetration)

Hydrocortisone – 200mg iv

Treat and monitor hyperkalaemia – (Calcium Gluconate, Salbutamol neb, frequent monitoring)
