Medications Paramedic

Question 1

Norepinephrine (levophed)

Answer 1

Class: sympathetic agonists

Mechanism of action: acts both on alpha and beta receptors as an agonist. Potent vasoconstrictor. Increases b/p. Alpha effects tend to be more profound

Indications: shock (maintain bp) severe hypotension and post resuscitation

Adverse reactions: palpations, anxiety, tachycardia, tremors

Dose: 1-30mcg/min via IV pump

Question 2

Dopamine

Answer 2

Class: Sympathetic agonist

Mechanism of action: Acts on alpha beta and dopamine receptors, which effects depend on dose. Alpha vasoconstriction. Beta increase HR/ contractility. Dopamine receptors increase blood flow kidneys/intestines.

Indications: hypotension, cardiogenic shock, bradycardia

Adverse reactions: N/A, palpations, headaches, nervousness

Dose: D1+D2 2-5mcg/kg/min Alpha 5-10mcg/kg/min

Beta 10-20mcg/kg/min Pedi 2-20mcg/kg/min

Question 3

Amiadrone

Answer 3

Class: Anti-Dysrhythmic

Mechanism of action: Prolong the action potential and refactor period, slows electrical conduction rate. Sodium, calcium, potassium channel blocker.

Indications: v-tach, v-fib, wide complex tachycardia

Contraindications: Hypersensitivity, Brady cardia

Adverse reactions: dizziness, drowsiness

Dose: arrest- 150-300mg IV/IO Stable 150mg over 10min IV/IO drip
