a-fib, atrial flutter with rapid ventricular response
side effects of diltizem
flushing, hypotension, bradycardia, chest pain, CHF, constipation, dizziness, dry mouth
side effects of amiodorone (Cordarone)
hypotension, bradycardia, arrhythmias, dry eyes, renal impairment, pruritis, OD-AV block
classification of dopamine
ionotropic agent, cardiac stimulant, vasopressor
dose of dopamine
2-20mcg/kg/min
indications for dopamine
drug of choice for hypotension or shock
side effects of dopamine
tachycardia or bradycardia, anginal pain, dyspnea, hypotension, nausea, vasoconstriction
side effects of labetolol
diaphoresis, dizziness, flushing, hypotension, numbness, nausea, ventricular dysrhythmias
classification of natrecor (Nesiritide)
cardiotonic, vasodilator
dosage of natrecor (Nesiritide)
initial 2mcg/kg followed by infusion of 0.01mcg/kg/min
Indications for natrecor (Nesiritide)
acutely decompensated CHF in pts who have dyspnea at rest or with minimal activity
side effects of natrecor (Nesiritide)
hypotension, abdominal pain, angina, anxiety, dizziness, fever, headache, leg cramps, rash
classification of nicardipine (Cardene)
Ca channel blocker, antihypertensive
Dosage of nicardipine (Cardene)
0.5-15mg/hr
indications for nicardipine (Cardene)
short term tx of HTN when oral therapy is not feasible or not desirable
Side effects of nicardipine (Cardene)
headache, HTN, hypoTN, N/V, tachycardia, OD=bradycardia following initial tachycardia, confusion, drowsiness, flushing, hypotension, palpitations, slurred speech
nitroprusside classification
antihypertensive, vasodilator
dose range for nitroprusside
0.1-5 mcg/kg/min
indications for nitroprusside
hypertensive emergencies
S/E of nitroprusside
abdominal pain, bradycardia, flushing, headache, hypotension, dizziness, muscle twitching, increased ICP
classification of norepinephrine
vasopressor
dosage of norepinephrine
2-4 mcg/min
indications for norepinephrine
favorite drug for ppl in shock, all hypotensive states
S/Es of norepinephrine
rare when used as directed- anxiety, chest pain, decreased CO, dyspnea, headache, ischemia, seizures, vomiting
classification of phenylephrine
vasopressor
dosage of phenylephrine
40-60 mcg/min. Initial may be 100-180mcg/min until BP is stable
indications for phenylephrine
helps maintain adequate BP
SEs of phenylephrine
bradycardia, headache, tingling extremities, V-tach, HTN, vertigo
dosage of propofal
25-200 mcg/kg/min, allow 5 mins btwn adjustments
SEs of propofal
apnea, bradycardia, dyspnea, hypotension, hypoventilation, nausea, upper airway obstruction, headache, green urine, abdominal cramping
