Drug administration plays a critical role in the field of emergency medical services (EMS), where paramedics are often the first responders to medical emergencies. The ability to administer drugs safely and effectively is essential for providing timely and appropriate care to patients in prehospital settings. This article provides guidelines for paramedics on drug administration in the field, covering medication safety, dosage calculation, routes of administration, and documentation.

Medication Safety

Ensuring medication safety is paramount when administering drugs in the field. Paramedics should adhere to the following guidelines:

  1. Verify Medication Orders: Before administering any medication, verify the order with medical control or refer to local protocols. Confirm the drug name, dosage, route of administration, and any specific instructions.

  2. Check Allergies and Contraindications: Assess the patient for known allergies or contraindications to the medication. If there are any concerns, consult medical control for guidance.

  3. Check Medication Expiry and Integrity: Ensure that the medication is not expired and check the integrity of the packaging. Discard any damaged or opened medication immediately.

  4. Double-Check Medication Labels: Read the medication label at least twice to confirm the drug name, dosage, and route of administration. Avoid distractions and interruptions during this process.

  5. Use the Five Rights of Medication Administration: Confirm the right patient, right medication, right dose, right route, and right time before administering any drug.

  6. Follow Proper Storage and Handling Procedures: Store medications in appropriate conditions, following manufacturers' recommendations. Properly dispose of expired or unused medications according to local regulations.

Dosage Calculation

Accurate dosage calculation is crucial to prevent medication errors and ensure patient safety. Paramedics should follow these guidelines:

  1. Know the Medication's Concentration: Familiarize yourself with the concentration of the medication you are administering. This information is typically found on the medication label or packaging.

  2. Convert Units if Necessary: Ensure that units of measurement are consistent. If needed, convert units to match the prescribed dosage. Use conversion tables or formulas as appropriate.

  3. Use Reliable References: Consult reliable references such as drug handbooks, medication apps, or online resources to verify dosages. Confirm the dosage range for the specific patient population and indication.

  4. Check for Weight-Based Dosages: Some medications require weight-based dosing. Ensure accurate weight measurement and use appropriate formulas or charts to calculate the correct dosage.

  5. Seek Clarification if Uncertain: If there are any doubts or discrepancies in dosage calculations, consult medical control or a pharmacist for clarification.

Routes of Administration

Paramedics may administer medications through various routes depending on the situation and the medication's properties. The following are common routes of administration:

  1. Intravenous (IV) Route: Administering medication directly into the patient's vein provides rapid onset and precise control over drug delivery. Follow aseptic techniques when preparing and administering IV medications.

  2. Intraosseous (IO) Route: When IV access is challenging, the IO route allows quick drug administration. Use appropriate equipment and follow established protocols for IO access and medication administration.

  3. Inhalation Route: Inhalation medications are delivered through nebulizers or metered-dose inhalers. Ensure proper technique and coordination between breaths and medication administration.

  4. Intranasal (IN) Route: Certain medications can be administered through the nasal mucosa. Follow local protocols and guidelines for proper administration and dosage.

  5. Subcutaneous (SC) and Intramuscular (IM) Routes: These routes are commonly used for medications that require absorption into the bloodstream or muscle tissue. Follow proper injection techniques and anatomical landmarks.

  6. Oral (PO) Route: Oral medications may be administered if the patient can safely swallow and local protocols allow. Ensure proper patient education and follow medication absorption guidelines.

Documentation

Accurate and timely documentation is essential for maintaining continuity of care and legal purposes. Paramedics should:

  1. Record All Medications Administered: Document all medications administered, including drug name, dosage, route, time of administration, and any relevant patient responses or adverse reactions.

  2. Use Standard Abbreviations: Follow approved medical abbreviations to ensure clarity and prevent misinterpretation. Avoid using non-standard or ambiguous abbreviations.

  3. Document Allergies and Adverse Reactions: Clearly document any known allergies or adverse reactions to medications to alert future healthcare providers.

  4. Include Patient Information: Include the patient's demographic information, vital signs, pertinent medical history, and the reason for medication administration.

  5. Sign and Date Entries: Sign and date all medication entries to indicate who administered the medication and when.

Conclusion

Proper drug administration is a critical skill for paramedics in the field. Following guidelines for medication safety, accurate dosage calculation, appropriate routes of administration, and thorough documentation helps ensure patient safety and quality care. Paramedics should maintain ongoing education and stay updated with local protocols and best practices to enhance their drug administration skills and provide optimal prehospital care.
