Dx DKA
Dx DKA = Diabetes – BG>11 or known diabetes and
Ketonaemia >3 AND acidosis – bicarb <15 or ph<7.3
Pathophysiology of primary hyeraldosteronism
Primary hyperaldosteronism – most common treatable and curable form secondary HTN.
Aldosterone production exceeds bodys requirements and is rel autonomous to the renin-angiotensin II system. Therefore excessive sodium reasbrotpion (and water) within distal nephron leading to HTN and suppression on renin-angiotensin II
Urinary loss Potassium and hydrogen ions, exchanged for sodium at distal nephron, may result in hypokalaemia and metabolic alkalosis if severe and prolonged
Mx hypoglycaemia
<4 with/without symptoms, conscious and able to swallow should have fast acting carb by mouth (Glucogel)
Can repeat after 15mins up to max 3 times.
Once >4 then give long acting carb to prevent it falling again
Hypoglycaemia that does not respond (<4 after 30-45mins or 3 tx cycles) then IM glucagon or glucose 10% iV infusion
If emergency and decreased LOC then IM glucagon can be given. If this isn’t effective after 10mins give IV glucose 10% infusion.
