hypoglycaemia Flashcards
1
Q
hypoglycaemia - presentation
A
SNS overdrive:
P up + BP, sats, RR normal
pale - peripheral vasoconstriction (adrenaline)
clammy - alpha receptors in sweat glands
neuroglycopaenia (g<3):
tonic-clonic convulsion
todd’s paresis - stroke mimic
bilateral upgoing plantars (only hypos + pontine haemorrhage cause this)
2
Q
hypoglycaemia - approach
A
A - maintain airway to prevent tongue obstruction
B - oxygen
C - pulse, BP, IV access, bloods
D - AVPU + glucose (recheck in 10 mins)
if glucose <4 - IV glucose + IM glucagon
g<4 = hypo
