Cardiac General Flashcards
Dosage of Nitroglycerine (paste)
Adult: 1-2 inches of paste over the chest wall. Cover with transparent wrap and secure with tape.
Ped: N/A
Ace Inhibitors
Blocks enzyme responsible for production of angiotensin II. Reduces BP.
Adult: Oral medication. Dosage Varies.
Ped: Oral medication. Dosage Varies
Class and indication of Nitroglycerin?
Vasodilator. Reduces preload and after load. Decreasing workload of the heart and its oxygen demand.
Angina, chest pain, HTN, CHF, pulmonary edema.
The dosage of Adenosine?
Adult: 6 mg IV push over 1-3 seconds (if no effect)
12 mg IV push over 1-3 seconds (2x)
Ped: 0.1 mg/kg IV push over 1-3 seconds (max 6 mg) {if no effect}
0.2 mg/kg IV push over 1-3 seconds (max 12 mg)
Class and Indication of Adenosine?
Antiarrhythmic that restores NSR by interrupting re-entry pathways and slowing conduction in the AV node.
STABLE re-entry SVT. (will not convert a-fib, a-flutter, or v-tach)
What is the bolus and infusion dosage of Amiodorone?
Adult: Bolus=300 mg IV push for pulseless v-fib/v-tach
(repeat) 150 mg IV push
Infusion=540 mg over 18hrs (2.2g max over 24hrs)
Ped: 5mg/kg over five minutes (repeat 15mg/kg)
Class and indication of Amiodorone?
Antiarrhythmic. Sodium and Potassium channel blocker which delays repolarization–increasing the action potential. Increasing PR / decreasing PVR.
Indications are v-fib, pulseless v-tach, unstable v-tach
What is the dosage of Atropine Sulfate?
Adult: 0.5 mg IV every 3-5 minutes (max 3 mg)
Ped: 0.02 mg/kg IV (minimum 0.1mg - maximum 1mg) (repeat once)
Dosage of Nitroglycerine (tablet)
Adult: 0.4 mg SL every 5 minutes until pain free (bp >100 systolic)
Ped: N/A
What is the infusion dosage of Lidocaine?
Adult: 1.5 mg/kg IV/IO (repeat half that dose or 0.75mg/kg)
(up to 3 doses/max 3mg/kg)
Ped: 1 mg/kg IV/IO (max 100 mg) (repeat 0.5 mg/kg
Class and indication of Lidocaine?
Antiarrhythmic. Sodium channel blocker that increases the recovery period after repolorization.
Indications are Ventricular arrhythmias.
What is the dosage of Epinephrine 1:10,000?
Adult: Arrest=1 mg IV/IO (repeat every 3-5 minutes)
Infusion=0.1-0.5 mcg/kg/min titrated
Ped: 0.1 mg/kg (max 1 mg)
Class and indication of Epinephrine 1:10,000?
Sympathomimetic. Vasoconstriction with positive inotropic, chronotropic, and dromotropic effects. Bronchial smooth muscle relaxation.
Indications include arrest, symptomatic bradycardia alternate to dopamine, when atropine and pacing are unseccessful.
What is the class and dose of Furosemide?
A loop diuretic used for treatment of CHF/pulmonary edema.
Adult: 40 mg IV/IO over 2 minutes
What is the class and dosage of Magnesium Sulfate?
An electrolyte that plays a role in muscular excitability.
Adult: 2 grams IV/IO over 2 minutes.
