cardiac arrest Flashcards
drug used for bradycardia
atropine
drug for hyperkalaemia
8.4% sodium bicarbonate
Calcium chloride
drug for hypomagnaesia
Magnesium sulfate
drug for t de p
Magnesium sulfate
drug for digoxin toxicity
Magnesium sulfate
where is adrenaline synthesised
adrenal medulla
adrenaline target
α and β adrenoceptors
adrenaline moa
Activation of α adrenoceptors leads to vascular smooth muscle contraction and peripheral vasoconstriction. Activation of β1 adrenoceptors leads to increased heart rate and force of contraction (contractility) i.e. it has positive chronotropic and positive inotropic effects.
adrenaline important adverse effects
hypertension with associated risk of cerebral haemorrhage
adrenaline common side effects
hyperglycaemia, metabolic acidosis
amidarone class
Class III anti-arrhythmics
amidarone target
non-selective for Na channel, Ca channel and α-adrenoceptors
amidarone moa
prolongs the cardiac action potential seen as an increase in the QT interval on the ECG
amidarone i used to treat
arrhythmia
common adverse effects of amiodarone
Corneal microdeposits
important side effects of amiodarone
Thyroid disorders – hypothyroidism, hyperthyroidism
Pulmonary fibrosis
Phototoxicity
Peripheral neuropathy
Optic neuritis/neuropathy (can lead to blindness)
Hepatotoxicity
Slate-grey skin discolouration
when taking amidarone what precautions should people take
avoid exposure to direct sunlight
wear high factor sunscreen while on this medication. dazzled by car headlights when driving at night
atropine drug class
antimuscarinic agent
atropine target
inhibits the muscarinic acetylcholine receptor
atropine treats what kind of cardiac arrest
cardiac arrest produced by stimulation of the vagus
