Introduction to EMT Pharmacology

EMT pharmacology focuses on a limited number of medications used to treat specific, life-threatening conditions. EMTs must possess a thorough understanding of each medication's mechanism of action, indications, contraindications, dosages, routes of administration, and potential side effects. Also, these medications are chosen for their ease of administration, rapid onset of action, and relatively low risk of adverse effects when used correctly. This knowledge is essential for safe and effective patient care.

Common Medications Administered by EMTs

EMTs typically carry and administer a limited range of medications, each serving a specific purpose. The specific medications and protocols may vary slightly depending on the local EMS system and medical director's guidelines. That said, some medications are consistently included in most EMT medication kits.

1. Oxygen (O2)

• Indication: Hypoxia (low blood oxygen levels), respiratory distress, shortness of breath, cardiac arrest.
• Dosage: Administered via nasal cannula (1-6 LPM), non-rebreather mask (10-15 LPM), or bag-valve mask (BVM) with supplemental oxygen. The flow rate depends on the patient's respiratory status and the device used.
• Route of Administration: Inhalation.
• Contraindications: Rare, but excessive oxygen can be harmful to some patients with certain underlying conditions. Always follow medical direction and assess the patient's oxygen saturation levels.
• Side Effects: Generally well-tolerated, but high concentrations can cause oxygen toxicity in prolonged use. Dryness of mucous membranes is possible.

2. Aspirin (acetylsalicylic acid)

• Indication: Chest pain suggestive of acute coronary syndrome (ACS), to prevent platelet aggregation and reduce clot formation.
• Dosage: Typically 160-325 mg chewed and swallowed.
• Route of Administration: Oral.
• Contraindications: Allergy to aspirin, active bleeding, history of ulcers, recent bleeding disorders.
• Side Effects: Gastrointestinal upset (nausea, vomiting, heartburn), bleeding, allergic reactions (ranging from mild rash to anaphylaxis).

3. Nitroglycerin (NTG)

• Indication: Chest pain suggestive of ACS (angina pectoris, myocardial infarction), to dilate coronary arteries and improve blood flow to the heart.
• Dosage: Typically 0.4 mg sublingually, repeated every 3-5 minutes up to a maximum of three doses or until pain is relieved. Dosage and frequency vary according to local protocols.
• Route of Administration: Sublingual (under the tongue).
• Contraindications: Hypotension (low blood pressure), use of certain medications (e.g., phosphodiesterase inhibitors), head injury, suspected right ventricular infarction.
• Side Effects: Hypotension, headache, dizziness, nausea.

4. Albuterol (Salbutamol)

• Indication: Wheezing, shortness of breath, respiratory distress suggestive of acute bronchospasm (asthma, COPD).
• Dosage: Typically 2.5-5 mg via metered-dose inhaler (MDI) or nebulizer. Dosage and frequency may vary depending on local protocols.
• Route of Administration: Inhalation (MDI or nebulizer).
• Contraindications: Hypersensitivity to beta-agonists.
• Side Effects: Tachycardia (rapid heart rate), tremor, nervousness, headache.

5. Epinephrine (Adrenaline)

• Indication: Anaphylaxis (severe allergic reaction), cardiac arrest. The specific dosage and route vary dramatically based on the indication.
• Dosage: For anaphylaxis, typically 0.3-0.5 mg IM (intramuscular) or 0.1 mg/kg IM for pediatric patients. For cardiac arrest, intravenous (IV) administration is usually reserved for paramedics. Dosage and route are strictly determined by local protocols and medical direction.
• Route of Administration: Intramuscular (IM) for anaphylaxis, intravenous (IV) for cardiac arrest (usually paramedic level).
• Contraindications: Generally contraindicated in the absence of specific indications like anaphylaxis or cardiac arrest.
• Side Effects: Tachycardia, hypertension (high blood pressure), anxiety, tremor, headache. Adverse effects are significantly heightened with intravenous administration.

6. Oral Glucose

• Indication: Hypoglycemia (low blood sugar), altered mental status suggestive of hypoglycemia.
• Dosage: Typically 15-30 grams. The exact form and amount depend on local protocols. Gel or paste is commonly used for its ease of administration.
• Route of Administration: Oral.
• Contraindications: Unconscious patient (risk of aspiration), inability to swallow.
• Side Effects: Generally well-tolerated, although nausea and vomiting are possible.

7. Naloxone (Narcan)

• Indication: Opioid overdose (respiratory depression, altered mental status due to opioid).
• Dosage: Typically 0.4 mg-2.0 mg intranasally or intravenously depending on local protocols. Multiple doses may be needed.
• Route of Administration: Intranasal (nasal spray), intravenous (IV). Intramuscular (IM) may also be available in some settings.
• Contraindications: Generally only contraindicated in the absence of opioid overdose.
• Side Effects: Withdrawal symptoms in opioid-dependent individuals (anxiety, agitation, nausea, vomiting).

Understanding Dosages and Routes of Administration

The dosage of each medication is crucial. Incorrect dosages can be ineffective or even harmful. EMTs must carefully follow established protocols and administer medications as prescribed by their medical director. Routes of administration also vary depending on the medication and patient condition. Understanding these variations is vital for safe and effective treatment. Because of that, for example, sublingual administration means placing the medication under the tongue, while intramuscular involves injecting the medication into a muscle. Intravenous implies administration into a vein, typically a skill performed by paramedics.

Medical Direction and Protocols

EMTs are always under the guidance of a medical director, a physician who oversees the medical aspects of the EMS system. Medical directors establish protocols that outline the conditions under which specific medications can be administered, the appropriate dosages, and the procedures to follow. EMTs must strictly adhere to these protocols to ensure patient safety and legal compliance. Any deviation from established protocols requires contacting medical control.

Documentation and Reporting

Accurate and thorough documentation is essential. EMTs must meticulously record all medications administered, including the time, dosage, route of administration, patient response, and any adverse effects. This documentation is vital for continuity of care and legal protection.

Continuing Education and Competency

EMT pharmacology is a constantly evolving field. EMTs are required to maintain their competency through ongoing continuing education and training. This ensures they remain updated on the latest medications, dosages, protocols, and best practices.
