Emergency Medications Flashcards
vasopressor used to optimize BP and cardiac output and improves perfusion and myocardial contractility
epinephrine
indication of epinephrine
nsg consideration
- pt in cardiac arrest caused by asystole, pulseless electrical activity (pulseless VT or VF)
NSG INTV
- administer 1 mg q 3-5 min via IV push or IO route
- peripheral IV admin. w/ 20 ml flush and elevate extremity (forearm)
increases systemic vascular resistance and BP
vasopressin
indication of vasopressin
nsg consideration
- alternative to epinephrine (not anymore)
- give 40 U IV one time only
vasopressor used to increase BP
norepinephrine
indication of norepinephrine
nsg consideration
- given for hypotension and shock
- 0.1-0.5 mg/kg/min as IV infusion (central line)
vasopressor used to increase BP and contractility
dopamine
indication of dopamine
nsg consideration
- hypotension and shock
- give 5-20 mcg/kg/min as IV infusion
blocks parasympathetic action; increased SA node automaticity and AV conduction
atropine
indication of atropine
nsg consideration
- symptomatic bradycardia (hemodynamically unstable w/ hypotension)
- give rapidly as 1 mg IV push; may repeat to dose of 3 mg
acts on sodium-potassium and calcium channels to prolong action potential and refractory period
amiodarone
indications of amiodarone
nsg consideration
used to treat pulseless VT and VF unresponsive to shock delivery
NSG INTV
- give 300 mg IV; give 2nd dose of 150 mg in 3-5 min
promotes adequate functioning of cellular sodium-potassium pump
magnesium sulfate
indications of magnesium sulfate
nsg consideration
Torsades de Pointes
give 1-2 g diluted in 10 mL D5W IN 5-20 MIN
used to treat atrial fibrillation and other conditions that cause irregular heartbeat
sotalol
