Medication Card Guidelines – New by Vicki Updated 10.2012 Medication Cards are part of the overall grade for EMSP 2348 Pharmacology Section. Keep in mind that the student is preparing the cards to take into the clinical setting where they MUST know the drugs completely before being allowed to administer them to a patient. The guidelines needed to successfully complete this assignment are as follows: 1. The cards need to be done on Index cards in a spiral notebook; the other alternative is to do them on index cards and then place them in a binder of some sorts so the cards do not “fall out” after completing them. I will NOT take them LOOSE or held together with a binder clip since they can come loose easily. 2. The size of the cards is up to the student in what you are willing to carry but keep in mind that the smaller they are makes it easier to place them in your lab coat. 3. The following information must be on EVERY card. a. Class b. Mechanism of Action c. Indications d. Contradictions e. Side Effects f. Precautions g. How Supplied h. Administration/Dosage 4. THEY MUST BE LEGIBLE IN YOUR HANDWRITING –not anyone’s else’s. 5. Supplied in this packet is some information to help. You will be responsible to complete the medications in this packet, but as health care evolves very rapidly, more medications may need to be added before Paramedic School is completed. A good example is frequently cardiac medications may be added or deleted due to new research. There will be adequate time to add these drugs if it is deemed necessary. 6. The Packet will NOT be scanned into computers and made into drug cards. Commercial Drug Cards are also NOT acceptable either. 7. CARDS MUST BE HANDWRITTEN 8. Cards are due the 1 st day of class, graded and then returned to the student. Keep in mind that this assignment will help prepare you for the EMSP 2348 Pharmacology Final exam which has ¾ of the questions on the medications themselves. 9.

Medication Card Guidelines – New by Vicki Updated 10.2012

Medication Cards are part of the overall grade for EMSP 2348 Pharmacology Section. Keep in mind that the student is preparing the cards to take into the clinical setting where they MUST know the drugs completely before being allowed to administer them to a patient. The guidelines needed to successfully complete this assignment are as follows:

1. The cards need to be done on Index cards in a spiral notebook; the other alternative is to do them on index cards and then place them in a binder of some sorts so the cards do not “fall out” after completing them. I will NOT take them LOOSE or held together with a binder clip since they can come loose easily.

2. The size of the cards is up to the student in what you are willing to carry but keep in mind that the smaller they

are makes it easier to place them in your lab coat.

3. The following information must be on EVERY card. a. Class b. Mechanism of Action c. Indications d. Contradictions e. Side Effects f. Precautions g. How Supplied h. Administration/Dosage

4. THEY MUST BE LEGIBLE IN YOUR HANDWRITING –not anyone’s else’s.

5. Supplied in this packet is some information to help. You will be responsible to complete the medications in this

packet, but as health care evolves very rapidly, more medications may need to be added before Paramedic School is completed. A good example is frequently cardiac medications may be added or deleted due to new research. There will be adequate time to add these drugs if it is deemed necessary.

6. The Packet will NOT be scanned into computers and made into drug cards. Commercial Drug Cards are also NOT acceptable either.

7. CARDS MUST BE HANDWRITTEN

8. Cards are due the 1st day of class, graded and then returned to the student. Keep in mind that this assignment will help prepare you for the EMSP 2348 Pharmacology Final exam which has ¾ of the questions on the medications themselves.

9. Under Side Effects Charts, the Key is the following: When it is underlined and has a “C”=COMMON; When it is Bolded and has italics= LT-Life Threatening

EPINEPHRINE (1:10,000)

Class: Sympathomimetic, vasopressor, bronchodilator Mechanism of Action - Catecholamine that stimulates alpha- and beta- adrenergic receptors 1. Beta1 stimulation leads to: - positive inotropic effects (↑ force of cardiac contraction) - positive chronotropic effects (↑ rate of cardiac contraction) - positive dromotropic effects (↑ conduction velocity) - 3 above help with rate post-arrest - increased cardiac output (CO) - increased myocardial oxygen requirements 2. Beta2 stimulation leads to: - peripheral vasodilation and bronchodilation 3. Alpha1 stimulation leads to peripheral vasoconstriction: - arterial / venous vasoconstriction (vasopressor) = increased SVR (perfusion pressure) - constriction to renal, mesenteric, coronary, pulmonary and cerebral vessels

- makes the heart more susceptible to direct countershock in cardiac arrest (Ventricular fibrillation) (due to increased hydrostatic pressure) = reason it is given during cardiac arrest

4. Inhibits histamine release (stops degranulation) during anaphylactic reaction (Effects start within 90 seconds and are short lived) Indications 1. Asystole 2. Ventricular-Fibrillation/pulseless Ventricular-Tachycardia 3. Pulseless electrical activity (PEA) 4. Severe anaphylaxis Contraindications 1. Hypersensitvity 2. Patients with underlying cardiovascular disease 3. Tachyarrhythmias 5. Hypovolemic shock 6. Not with alkaline drugs Side Effects

DOPAMINE (INTROPIN)

Class: Sympathomimetic, vasopressor Mechanism of Action Catecholamine that stimulates dopaminergic, beta and alpha adrenergic receptors (dose dependent) Naturally occurring precursor of norepinephrine 1. Low doses (dopaminergic stimulation) leads to: (0.5 to 2 µg/kg/min) – NOT used in the field - Renal, mesenteric, cerebral, coronary vasodilation - Increased urinary output 2. Intermediate doses (Beta1 stimulation) leads to: (2 to 10 µg/kg/min) - Positive inotropic response (↑ force of cardiac contractions) (β1) - Positive chronotropic response (↑ rate of cardiac contractions) (β1) - Positive dromotropic effects (↑ conduction velocity) - Increased cardiac output (CO) (β1) - Increased myocardial oxygen requirements (β1) 3. High doses (Alpha1 stimulation) leads to peripheral vasoconstriction: (10 to 20 µg/kg/min) - Arterial and venous vasoconstriction (vasopressor) - Increased SVR - Vasoconstriction to renal, mesenteric, and coronary vessels Indications 1. Cardiogenic shock 2. Neurogenic shock 3. Septic shock 4. Hypotension that occurs after return of spontaneous circulation (post-arrest) 4.

CARDIAC GLYCOSIDES

ONE OF THE OLDEST MEDICATIONS KNOW TO HUMANS. THEY INCREASE FORCE (INOTROPIC) OF CONTACTIONS. WHEN USED FOR CHF THEY INCREAS CARDIAC OUTPUT BY REDUCING LEFT VENTRICULAR DIAMETER AND DECREASE VENOUS PRESSURE. THESE EVENTS HASTEN THE REDUCTION OF PERIPHERAL AND PULMONARY EDEMA. THE THERAPEUTIC INDEX (THERAPEUTIC DOSE / TOXIC DOSE) OF DIGITALIS IS LOW, SO THE POSSIBILITY OF DIGITALIS TOXICITY SHOULD ALWAYS BE CONSIDERED WITH PEOPLE ON THIS DRUG. DIGITALIS IS A POTENT AND POTENTIALLY TOXIC DRUG.

EPINEPHRINE (1:1,000) Class: Sympathomimetic, vasopressor, bronchodilator Mechanism of Action - Catecholamine that stimulates alpha- and beta- adrenergic receptors 1. Beta1 stimulation leads to: - positive inotropic effects (↑ force of cardiac contraction) - positive chronotropic effects (↑ rate of cardiac contraction) - positive dromotropic effects (↑ conduction velocity) - increased cardiac output (CO) - increased myocardial oxygen requirements 2. Beta2 stimulation leads to: - peripheral vasodilation and bronchodilation 3. Alpha1 stimulation leads to peripheral vasoconstriction: - arterial / venous vasoconstriction (vasopressor) = increased SVR - constriction to renal, mesenteric, coronary, and cerebral vessels - pulmonary vasoconstriction

- making the heart more susceptible to direct countershock in cardiac arrest (Ventricular fibrillation) = reason it is given during cardiac arrest

4. Inhibits histamine release (stops degranulation) during anaphylactic reaction (Effects start within 90 seconds and are short lived) Indications 1. Acute asthma attacks 2. Exacerbation of some forms of COPD 3. Mild anaphylaxis 4. Symptomatic Bradycardia (refractory, not responding, to oxygen and atropine) (infusion) 5. Symptomatic heart blocks (second type II and third degree) (infusion) Contraindications 1. Hypersensitvity 2. Patients with underlying cardiovascular disease 3. Tachyarrhythmias 4. Not with alkaline drugs 5. Shock 6. Patients with hypertension
