Vasoactive Drips Quiz

Vasoactive Drips Overview

• Vasoactive medications are critical in managing hypotension and shock, providing essential support to cardiovascular function.

Levophed (Norepinephrine)

• Levophed is an alpha/beta-agonist, which induces vasoconstriction and elevates blood pressure.
• Indicated for severe hypotension, shock, or bradycardia.
• Contraindicated for patients with a sulfite allergy.
• Initial drip can start at 0.5 mcg/min, adjusting for systolic blood pressure (SBP) and heart rate.
• Rapid onset with a short half-life; requires monitoring every 5 minutes during titration.

Epinephrine

• Used as the first-line treatment for cardiac arrest scenarios including asystole and profound hypotension.
• Works by stimulating the heart and improving blood flow.
• Administered via drip or bolus during resuscitation efforts.

Dobutamine

• Primarily utilized for cardiogenic shock, enhancing cardiac contractility.
• Acts similar to a balloon pump by reducing afterload while increasing heart rate and contractility.
• Especially effective in patients with heart failure and related hypotension.

Dosing Considerations

• Epinephrine can be infused at various rates, with adjustments based on patient response and vital signs.
• In one scenario, a patient receiving 2 mcg/min of epinephrine through a specific concentration results in an infusion rate of 30 ml/hr.
• Always verify physician's orders before titrating medications to ensure safety and adherence to treatment parameters.

Clinical Scenarios

• Patients presenting with hypotension and weak vital signs often require prompt administration of vasoactive drips.
• Continuous monitoring in the ICU, along with clear parameters for medication adjustments, is crucial for optimizing patient outcomes.
• Addressing persistent hypotension after fluid resuscitation is essential; further vasoactive support may be warranted.
