Medication Administration in Emergency Medical Services

Introduction to Medication Administration for EMTs

• Overview of medication administration practices for Emergency Medical Technicians (EMTs).

Situational Considerations in Medication Administration

• Importance of understanding the environment where medication is stored or used.

  • Example: If a medication is left in a kitchen sink, exposure to light and temperature could impact efficacy.

• Querying the patient about expiration dates and usage history.

  • Importance of determining when the patient last used the medication and its effectiveness.

Nitroglycerin for Angina

• Patient education on nitroglycerin use for chest pain (angina).

  • Dosage: If chest pain occurs, take one sublingual nitroglycerin tablet, then every 10 minutes up to three tablets until pain is relieved or medical assistance is obtained.

  • Definition: Angina is characterized by chest pain that occurs during stress and is relieved by rest and medication.

• Potential outcomes if medication does not relieve pain:

  • Possibility of a myocardial infarction (heart attack).

  • Assessment of medication efficacy; expired or improperly stored medication might be ineffective.

Types of Medication Administration Techniques

• Peer-Assisted Medication Administration:

  • Patient self-administers medication from EMT assistance.

• Patient-Assisted Medication Administration:

  • EMT provides medication for the patient to administer.

• EMT-Administered Medication:

  • EMT directly administers the medication to the patient.

• Necessity of following state and local protocols and consulting medical control when uncertain.

Activated Charcoal Administration

• Form: Activated charcoal can be administered in tablet form or as a powder mixed with liquid.

• Cautions: Only administer this medication when arriving at a healthcare facility to manage potential vomiting (expect tar-like consistency).

• Function: Binds to poisons in the gastrointestinal tract, thereby preventing absorption into the bloodstream.

• Case Study:

  • Administered to a child who potentially ingested Trazodone; used to safely detoxify the system without causing harm.

Oral Medications

• Oral Glucose:

  • Administration for hypoglycemia, essential for energy.

  • Contraindications: Avoid giving to unconscious patients who cannot protect their airways.

• Aspirin:

  • Properties: Reduces inflammation, fever, and pain while inhibiting platelet aggregation.

  • Importance in heart conditions: Helps improve blood flow during a heart attack.

  • Contraindications:

  • Allergies (not merely side effects), liver damage, bleeding disorders, asthma, and not advised for children.

Nitroglycerin Details

• Dosage: 0.4 milligrams per tablet, various forms (including spray).

• Administration: Sublingually for angina relief.

• Drug Interactions:

  • Contraindicated with erectile dysfunction medications, which are vasodilators and pose risks for severe hypotension.

• Case Narrative:

  • Interaction with a patient who denied using erectile dysfunction medication but had visible symptoms leading to the truth.

Emergency Assessment and Communication

• Importance of clear communication with the patient in distress.

  • Example: Explaining the severe implications of refusal for transport during a heart attack.

  • Reinforcement through visual assessment of the patient's condition may change their decision.

Epinephrine and Naloxone Use

• Epinephrine:

  • Actions: Stimulates heart rate and blood pressure, part of the fight-or-flight response.

  • Administration: Utilized during severe allergic reactions (anaphylaxis) via autoinjector (EpiPen).

• Naloxone:

  • Actions: Reverses opioid overdoses without harmful effects if no opioids are present.

  • Delivery Method: Typically administered intranasally or via syringe.

Oxygen Administration

• Critical for cellular function and survival.

• Delivery Methods: Via non-rebreather masks or nasal cannula, depending on patient's condition.

Metered Dose Inhalers (MDI)

• Definition: Designed for consistent dosing for respiratory illnesses; operates via a nebulizer for inhalation-based medication delivery.

• Patient education on dosage and functionality.

Patient Assessment and Medication History

• Comprehensive patient assessment to gather medication history, including prescription medications and over-the-counter drugs.

• Special considerations for the elderly population who may curtail clarity about their medical history.

Error Management in Medication Administration

• Protocols for addressing medication errors include:

  • Acceptance of responsibility, immediate patient care, notification of medical control, and thorough documentation.

• Importance of learning opportunities from errors and continuous education from supervisors and medical directors.

Pharmacology Basics

• Definition: Study of how drugs interact with the body's systems.

• Understanding different administration routes by their speed of effect (e.g., intravenous being the fastest).

Case Scenarios and Applied Knowledge

• Real-life examples to emphasize the intricate relationship between medication knowledge and clinical judgment in emergencies.

• Situational strategies used in response to patient conditions, refining understanding for clinical practices.

• Assessing patient symptoms, urgency, and treatment response to enhance critical intervention skills.

Conclusion

• Reiteration of critical importance of detailed knowledge of medication, administration protocols, and clinical decision-making for EMTs.

• Encouragement for ongoing education and situational preparedness in the field.
