8 Drugs Every ICU Nurse Needs to Know

These drugs are used frequently in the ICU setting. It is imperative that you understand what these drugs are and when they are to be used.

When I started on my current unit I had no idea what these drugs were. I had a vague idea, but really, I was pretty clueless. I had spent the last few months just trying to pass class. Unfortunately, I didn’t have a critical care class. (Which I really wished we would have!)

Here’s a quick guide to 8 drugs that we use frequently in emergency situations. ALCS (Advanced Cardiac Life Support).

  1. Adenosine
    An endogenous nucleoside, slows conduction down through the AV node. Treats supraventricular tachycardia and sometimes atrial tachycardia (but I’ve never personally seen that). Extremely short half life- <10 seconds.
  2. Amiodarone
    Antiarrhythmic that effects the sodium, potassium, and calcium channels. Vasodilates. Used in V tach, V fib, and sinus tachycardia.
  3. AtropineAntocholinergic, enhances the conduction in the AV node. Drug of choice in treating bradycardia.
  4. Epinephrine
    Potent cathcholamine. Increases heart rate, blood pressure. Used to treat Asystole, V tach, V fib, or bradycardia.
  5. Lidocaine
    Antiarrhythmic used alternatively to Amioderone. Treats V fib or V tach.
  6. Procainamide
    Antiarrhythmic, used to treat sustained V tach.
  7. Sotalol
    Beta Blocker. Treats A fib or A flutter.
  8. Vasopressin
    Synthetic antiarrhythmic. Used to treat Asystole, V tach, or V fib.

Opioid Comparison Chart

Opioids are a class of drugs that are used to relieve pain. They work by binding to opioid receptors in the brain and spinal cord. Opioids can be very effective in relieving pain, but they can also be addictive and dangerous.

The potency of an opioid is measured by how much stronger it is compared to morphine. Morphine is the standard by which all other opioids are measured.

The following chart compares the potency of some common opioids:

Mnemonics for Opioids

There are a few mnemonics that can be used to help remember the potency of some common opioids.

M-M-H-H: Methadone, Morphine, Heroin, Hydrocodone
F-O-X: Fentanyl, Oxycodone
These mnemonics can be helpful for nurses and other healthcare professionals who need to remember the potency of different opioids.
