Sodium Bicarbonate
|
Class: Alkalinizing agent
Pharm: raises PH and binds tricyclics to serum protiens by alkalinizing Indications: Tricyclic antidepressant overdose; cardiac arrest with long downtime; crush injury pretreatment. Contra: Hypoxic lactic acidosis Side FX: alkalosis, worsens cellular acidosis in hypoperfusion states Dosage: 1.0 mEq/kg of 8.4% IVP Crush injury: 1.0 mEq/kg IV and/or 0.25 mEq/kg/hr infusion |
|
Verapamil
|
Class: Calcium Channel Blocker
Pharm: relaxation of vascular smooth muscle, causing vasodilation. Slows conduction through AV node decreasing HR, decreases rapid ventricular response with atrial tach. Indications: PSVT refractory to Adenosine; Control of rapid V response with A-Fib and A-flutter Contra: Hypotension, Cardio shock; V-tach Side FX: Hypotension, N/V, headache, dizziness Dosage: 2.5--5mg over 2-3 min IV; may repeat in 15-30 min with 5--10mg over 2-3 min. MAX dose 20mg |
|
Magnesium Sulfate
|
Class: Electrolyte, Antiarrhythmic
Pharm: depressant of smooth, cardiac, and skeletal muscle by decreasing acetylcholine. CNS Depressant Indications: Recurrant/refractory V-Fib/pulseless V-Tach; Torsades de Pointes; Convulsions/siezures from toxemia due to pregnancy. Contra: Heart blocks, hypotension Side FX: respitory depression, bradycardia Dosage: V-Fib/PL V-tach after lidocaine 1--2g IVP; Torsades 1--2g in 100mL over 5-60 minutes drip; Pregnancy 2--4g IVP over 3 min followed by 1--2g/hr drip; Post infarction/Hyperkalemia 1--2g in 100mL over 60 minutes |
|
Amiodarone
|
Class: Antidysrhythmic
Pharm: Prolongs duration of the action potential and effective refractory period. Decreases AV conduction velocity and sinus node function. Indications: VF and PLVT refractory to defib; torsades de pointes; rate control in A-Fib or A-flutter when all else fails. Contra: Hypotension, hypersensitivity Side FX: vasodilation, hypotesnion Dosage: VF/PLVT 300mg IVP, after 3-5 min repeat 150mg IVP Wide Complex Tach 150mg over 10 minutes, may repeat every 10 min as needed. Main infusion 1mg/min for 6 hours |
