Poison
  • Any substance whose chemical action can damage body structures or impair body functions

Substance Abuse

  • The knowing misuse of any substance to produce a desired effect
identifying the patient and the poison
Identifying the Patientand the Poison
  • If you suspect poisoning, ask the patient the following questions:
    • What substance did you take?
    • When did you take it or (become exposed to it)?
    • How much did you ingest?
    • What actions have been taken?
    • How much do you weigh?
determining the nature of the poison
Determining the Natureof the Poison
  • Take suspicious materials, containers, vomitus to the hospital.
  • Provides key information on:
    • Name and concentration of the drug
    • Specific ingredients
    • Number of pills originally in bottle
    • Name of manufacturer
    • Dose that was prescribed
inhaled poisons
Inhaled Poisons
  • Wide range of effects
    • Some inhaled agents cause progressive lung damage.
  • Move to fresh air immediately.
  • All patients require immediate transport.
absorbed poisons
Absorbed Poisons
  • Many substances will damage the skin, mucous membranes, or eyes.
  • Substance should be removed from patient as rapidly as possible.
  • If substance is in the eyes, they should be irrigated.
  • Do not irrigate with water if substance is reactive.
ingested poison
Ingested Poison
  • Poison enters the body by mouth.
  • Accounts for 80% of poisonings
  • May be accidental or deliberate
  • Activated charcoal will bind to poison in stomach and carry it out of the body.
  • Assess ABCs.
injected poisons
Injected Poisons
  • Usually result of drug overdose
  • Impossible to remove or dilute poison once injected
  • Prompt transport
emergency medical care
Emergency Medical Care
  • External decontamination is important.
  • Care focuses on support: assessing and maintaining ABCs.
  • You may be permitted to give activated charcoal for ingested poisons.

  • Always give supplemental oxygen and prepare for vomiting.
sedative hypnotic drugs
Sedative-Hypnotic Drugs
  • These drugs are CNS depressants and alter level of consciousness.
  • Patients may have severe respiratory depression and even coma.
  • The main concern is respiratory depression and airway clearance, ventilatory support, and transport.

  • Symptoms may not appear until it is too late.
  • Liver failure may not be apparent for a full week.
  • Gathering information at the scene is very important.
other alcohols
Other Alcohols
  • Methyl alcohol and ethylene glycol are more toxic than ethyl alcohol.
  • May be taken by chronic alcoholics who cannot obtain drinking alcohol
  • More often taken by someone attempting suicide

food poisoning
Food Poisoning
  • Salmonella bacterium causes severe GI symptoms within 72 hours.
  • Staphylococcus is a common bacteria that grows in foods kept too long.
  • Botulism often results from improperly canned foods.
care for food poisoning
Care for Food Poisoning

plant poisoning
Plant Poisoning
  • Several thousand cases of plant poisonings occur each year.
  • If you suspect plant poisoning:
    • Assess the patient’s airway and vital signs.
    • Notify poison control center.
    • Take the plant to the emergency department.
    • Provide prompt transport.
myth and reality
Myth and Reality
  • Everyone has symptoms of mental illness problems at some point.
  • Only a small percentage of mental health patients are violent.
  • Perfectly healthy people may have symptoms occasionally.
defining behavioral emergencies
Defining Behavioral Emergencies
  • Behavior
    • What you can see of a person’s response to the environment and his or her actions
  • Behavioral crisis
    • Any reaction to events that interferes with activities of daily living or that becomes unacceptable to the patient, family, or others
    • A pattern, not an isolated incident
causes of behavioral emergencies
Organic Brain Syndrome

Caused by disturbance in brain tissue function

Functional Disorder

Cannot be traced to change in structure or physiology of the brain

Causes of Behavioral Emergencies
causes of organic brain syndrome
Causes of Organic Brain Syndrome
  • Sudden illness
  • Recent trauma
  • Drug or alcohol intoxication

  • Keep in mind the suicidal patient may be homicidal as well.
medicolegal considerations
Medicolegal Considerations
  • Mental incapacity may take many forms.
  • Once a patient has been determined to have an impaired mental capacity, you must decide if care is needed.
  • Do not leave the patient alone.
  • Obtain help from law enforcement as necessary.
consent
Consent
  • When a patient is not mentally competent, the law assumes that there is implied consent.
  • The matter is not always clear-cut with psychiatric emergencies.
  • If you are not sure about the situation, request law enforcement assistance.
limited legal authority
Limited Legal Authority
  • As an EMT-B, you have limited legal authority to require or force a patient to undergo care.
  • Police may put a patient in protective custody to allow you to provide care.
  • Know your local laws and protocols.
restraints
Restraints
  • You cannot restrain a patient unless it is an emergency.
  • Transport a disturbed patient without restraints if possible.
  • If you must restrain the patient, use only reasonable force.
    • Law enforcement personnel should be involved.
potentially violent patients
Potentially Violent Patients
  • Use a list of risk factors to assess the level of danger:
    • Past history
    • Posture
    • Scene
    • Vocal activity
    • Physical activity
other factors to consider for potential violence
