Acute digoxin toxicity
Time course: initial toxic effects of nausea and vomiting occur at 2-4 hours, peak serum levels at 6 hours and life-threatening cardiovascular complications at 8-12h
GI: anorexia, nausea, vomiting, diarrhoea, abdominal pain
METABOLIC: hyperkalaemia (early sign of significant toxicity)
METABOLIC: hyperkalaemia (early sign of significant toxicity)
CVS: enhanced automaticity (atrial tachycardia (e.g. flutter, AF) with AV block, VF, VT, ventricular ectopic beats), bradyarrhythmias (Conduction delays / blocks, slow or regularised AF), hypotension, shock
CNS: lethargy, confusion
Acute toxicity is potentially lethal and digibind is indicated when:
cardiac arrest
life-threatening dysrhythmia
K >5mM
>10mg ingested (adult), >4mg ingested (child)
>15 nM level (>12ng/mL)
cardiac arrest
life-threatening dysrhythmia
K >5mM
>10mg ingested (adult), >4mg ingested (child)
>15 nM level (>12ng/mL)
Nonselective alpha-blockers may cause adverse effects such as hypotension, weakness, tachycardia, and tremulousness.
