Study Notes
Paramedic Drugs: Onset and Duration
- Paramedics utilize a range of medications to treat patients in the field, aiming to address various medical conditions and stabilize patients prior to hospital transfer.
- The choice of medication depends on the specific patient presentation, and the drug's onset and duration of action are crucial factors in determining efficacy and safety.
- Onset of action refers to the time it takes for a drug to begin its therapeutic effect. This is important as it dictates how quickly a patient's condition can be addressed.
- Duration of action refers to the length of time a medication maintains its therapeutic effect. This is crucial for patient management, determining the frequency of necessary administrations.
- Drug onset and duration significantly influences the frequency of dosing required for adequate clinical response.
Specific Drug Examples: General Considerations
- Different classes of medications have varying mechanisms of action, affecting both onset and duration. For example, intravenous (IV) administration typically results in a faster onset compared to oral administration.
- Factors like patient weight, metabolism, and concurrent conditions can impact how a drug acts.
- The specific route of administration (e.g., IV, IM, subcutaneous) can also influence these parameters.
- Drug interactions with other medications or patient's current conditions can alter how the drug works and how long the effects last. A thorough patient history, including allergies and current medication, is crucial.
Specific Drugs and Example Onsets/Durations (Note: This is not an exhaustive list.)
- Epinephrine (Adrenaline): Typically administered intravenously or intramuscularly. Onset: rapid, within minutes; duration: relatively short, typically less than an hour. Used in anaphylaxis, cardiac arrest, and severe allergic reactions.
- Atropine: Used to treat bradycardia. Onset: relatively rapid, within minutes; duration: moderate, typically lasting several hours.
- Naloxone: Opioid overdose reversal agent. Onset: rapid, typically within minutes; duration: relatively short, often requiring repeat administration.
- Glucose (dextrose): Used to treat hypoglycemia. Onset: rapid, usually within minutes when given intravenously; duration: variable, depending on the amount administered and patient's metabolic status.
- Aspirin: Used to reduce fever and pain, or to reduce the risk of clotting. Onset: variable, determined by the route of administration, oral tends to be slower, IV is much quicker; duration: prolonged for pain relief, may be less so for platelet effects.
- Oxygen: Although not a medication, oxygen administration has crucial and rapid onset (almost immediate) in cases of hypoxia. Duration of benefit is relative to the administration source and flow.
Important Considerations for Paramedic Practice
- Accurate documentation of administered medications, their dosage, route, and time of administration is paramount for patient care and for any potential legal requirements.
- Paramedics must be aware of drug incompatibilities and potential side effects.
- Patient monitoring is essential to assess the effectiveness and safety of administered medications.
- Recognize that patient response varies, and constant reevaluation is critical for adjusting treatment as needed.
