Description

Nitroprusside purpose decreases preload and afterload by vasodilation (mainly afterload) Dobutamine mechanism of action contractility Dopam ine at a low-end dose "renal dose" 0.5-4mcg/kg/min increases renal and mesentric perfusion Dopamine at a mid-range dose 4-10mcg/kg/min increases contractility and heart rate Dopamine at a high-range dose greater than 10mcg/kg/min vasoconstriction and increases BP Dopamine and Levophed infiltration leads to tissue necrosis Dopamine antidote regitine (phentolamine) TpA monitor for bleeding-hemorrhagic CVA diltiazem (cardizem) works by? (calcium channel blocker) slows ventricular rate by slowing conduction through the SA and AV node Diltazem (cardizem) biggest effect on which hemodynamic hypotension diltazem is used for patients with a-fib or a-flutter amiodarone (Cordarone) is a antiarrythmic prolongs the cardiac duration You MUST use a __________ when using amiodarone infusion 0.22 micron filter Watch out for ____________ in patients on a amiodarone infusion hypotension, prolongation of QT interval and bradycardia amiodarone is used for patients with a-fib, a-flutter and VT how much amiodarone is given to a stable VT with a pulse and a unstable pulseless VT/VF? 150mg over 10min for VT with pulse 300mg push; repeat x1 at 150mg Epinephrine has what effect on the body? increases HR, BP, and contractility what is the first line drug for pulseless arrest? Epinephrine What rhythms are considered fatal? V-fib, Vtach (pulseless), and asystole Epinephrine is also given for? anaphylaxis and as a vasopressor for hypotension Heparin is used for? Antidote is? anticoagulant Protamine Sulfate What is the osmotic diuretic of choice to decrease intracranial pressure? mannitol
