    Study Notes

    Substance Abuse and Toxicology Basics

    • Definition of substance abuse: Knowingly misusing substances for desired effects.
    • Importance of activated charcoal in treatment: Binds to substances, preventing their absorption.

    Emergency Response to Overdoses

    • In suspected overdose cases, prioritize consciousness and safety, such as administering activated charcoal when the patient is alert.
    • Signs of intoxication may be confused with medical conditions like syncope; understanding what symptoms overlap is crucial.

    Poisoning and Treatment Protocols

    • Injected poisons rapidly absorb into the body, making them difficult to treat or remove.
    • Administer activated charcoal for certain ingestions, but it is contraindicated in cases of unresponsiveness or specific toxins like alkali.

    Recognizing Drug Overdoses

    • Sympathomimetic drug overdoses show tachycardia as a primary symptom.
    • Heroin overdoses may result in unresponsiveness, bradycardia, and shallow breathing; act quickly with ventilation support.

    Considerations in Trauma and Alcoholism

    • Heavy alcohol use can impair blood clotting, increasing the risk of profuse internal bleeding in trauma cases.
    • Always ensure ventilation support for severely intoxicated patients, especially when demonstrating low respiratory rates and weak pulses.

    Specific Poisons and Bacterial Infections

    • The Salmonella bacterium is directly responsible for causing food poisoning.
    • Treatment of absorbed poisons focuses on safe removal or dilution of the toxin involved.

    Pediatric Considerations in Poisoning Cases

    • For a 4-year-old who ingested acetaminophen, administer 15 g of activated charcoal while monitoring for any signs of distress.

    Vital Signs and Symptoms of Overdose

    • Cocaine overdose can present vital signs such as elevated blood pressure (200/100 mm Hg) and a fast pulse (150 beats/min).
    • Be particularly vigilant for signs of vomiting after administering activated charcoal, as it can complicate treatment.

    Safety and Environment

    • When entering a scene of potential overdose, assess for personal hazards to ensure the safety of the responder and the patient.
    • Initial questions to patients should focus on substance specifics rather than motivations for use, which may not impact immediate treatment.
