Emergency Drugs You Can LEAN On


This post is primarily intended for nurses like me who wanted to 'freshen' up their knowledge and expertise in the different fields of our nursing profession. However for those who are wide-readers and would like to learn a thing or two about what nurses do especially in the clinical set up, then you're free and welcome to follow my nursing blog posts.

It's almost been like half a decade already since I graduated from the college of nursing. Although I'm keeping myself employed in an international hospital setting since the time I took and passed the Philippine Nursing Licensure Examination as well as the Health Authority Abu Dhabi Nursing Exam in Abu Dhabi United Arab Emirates, it couldn't be denied that some of the most important detailed concepts and theories in nursing that I've learned when I was still a student have already been rusted and forgotten. So now, I make sure that everyday I would read and review at least a page of my nursing notes and nursing articles to keep myself updated in the current trends of nursing which could certainly help me in delivering an excellent nursing care service to my patients.

And this time, lets start by having a very short review on some common yet pertinent drugs administered in the Emergency Room. The calls it the Emergency Drugs you can LEAN on:

Lidocaine - is a common local anaesthetic and class 1b antiarrythmic drug. It works in two ways:

1. As an anaesthetic it works by blocking the pathway of pain signals along nerves. It does this by stopping the sodium from entering the nerve ending at site of the pain. This prevents an electrical signal from building up and passing along the nerve fibers to the brain.

2. As an antiarrhythic it works by decreasing the sensitivity of of heart muscle to electrical impulses. This slows the conduction of electrical signals, which in turn, helps restore a regular heart rhythm.

Epinephrine -is both a hormone and a neurotransmitter. It is a non-selective agonist to all adrenergic receptors. It is used to manage patients with bronchial asthma because of its bronchodilating effect. While it is used as a treatment for patients with open angle glaucoma because of its vasoconstrictive action leading to decrease in aqueous production and increase in outflow activity.

Atropine - is an anticholinergic medication. It works by blocking the effects of acetylcholine resulting in increased heart rate, dilation of pupils, reduced salivation and other secretions.

Naloxone (Narcan) - is a pure opioid antagonist used to counter the effects of opioid overdose like morphine and heroin. It competes for opiate receptor sites within the CNS, thereby preventing the action of both the endogenous and xenobiotic opiates on these receptors without producing any effects in itself.

I am hoping you learn something today. Until next time:)
