Trauma Medications: In emergency situations, quick and accurate administration of medications is crucial. This guide will provide a concise overview of common trauma medications, their actions, uses, and important considerations.
Lidocaine
Action: Lidocaine is a local anesthetic that temporarily numbs and relieves pain by blocking the transmission of nerve impulses. In higher doses, it can also be used intravenously to treat ventricular arrhythmias (irregular heart rhythms) like ventricular fibrillation (V-fib) and ventricular tachycardia (V-tach). It does this by suppressing the diastolic depolarization of ventricular cells.
Use For:
- Local anesthetic (injections or topically)
- Ventricular arrhythmias (IV administration)
Important Considerations:
- Lidocaine can cause side effects such as dizziness, drowsiness, and numbness.
- It should be used with caution in patients with liver or heart disease.
Epinephrine
Action: Epinephrine stimulates alpha and beta adrenergic receptors, leading to various effects:
- Relaxes lung smooth muscle, promoting bronchodilation (opening of airways)
- Constricts blood vessels in skeletal muscle, increasing blood flow to vital organs
Use For:
- Anaphylaxis (severe allergic reaction)
- Bronchospasm (narrowing of airways)
- Cardiac arrest (as part of advanced life support)
Important Considerations:
- Epinephrine can cause side effects such as anxiety, restlessness, and rapid heart rate.
- It should be used with caution in patients with hypertension or heart disease.
- It can cause bronchoconstriction in certain conditions like asthma and chronic simple glaucoma, so it should be used with caution in these cases.
Atropine
Action: Atropine blocks the action of acetylcholine, a neurotransmitter that slows down the heart rate. This can increase the heart rate and decrease respiratory secretions.
Use For:
- Sinus bradycardia (slow heart rate)
- Decreasing respiratory secretions (e.g., during surgery)
Important Considerations:
- Atropine can cause side effects such as dry mouth, blurred vision, and urinary retention.
- Overdose of anticholinergic drugs (including atropine) can lead to serious complications.
Narcan (Naloxone)
Action: Narcan is an opioid antagonist, meaning it blocks the effects of opioids. It is used to reverse opioid overdose.
Use For:
- Opioid-induced toxicity (e.g., respiratory depression)
- Neonates affected by narcotics given during labor
Important Considerations:
- Narcan has a short duration of action, so multiple doses may be needed.
- It can cause withdrawal symptoms in opioid-dependent individuals.
