Lesson 24: Poisoning
You Are the
Emergency Medical Responder
Your police unit is summoned to a residence on a
report of an unconscious person. When you arrive
and size-up the scene, you discover parents with
their 2-year-old child. The mother is distraught
and says she found her toddler on the kitchen
floor very drowsy. She noticed that the under-thesink cabinet door was open, and there was a
bottle of liquid kitchen cleaner lying next to the
child. She called 9-1-1 because he was not
responding when she tried to wake him up.

Emergency Medical Response
Poison Control Centers
 Specialized health care centers that provide
information on poisons and suspected poisoning
emergencies
 24-Hour Poison Help Hotline: 1-800-222-1222
 U of U
 Pharmacists, physicians, nurses, toxicologists
 70% of poison exposure cases can be managed
over the phone
Emergency Medical Response

 Victim's age and weight
 Any symptoms the victim has related to the
poisoning

Ingested Poisons
Ipecac
 Action
 Local irritant & vomit
center stimulation
 Onset of action
 20-30 minutes in
97% people
 Advantages
 Easy to use
 Was over-thecounter
 Disadvantages
 Poison can pass into small
intestine during 20-30
minute wait for vomiting
 Delays additional care,
can’t be mixed with
activated charcoal
 Only 30% - 50% stomach
contents recovered = leaves
50% - 70% poison
 Complications
 Aspiration, esophageal
rupture, death

industrial accidents, and Weapons of Mass Destruction
(WMD)
 CO is the leading cause of poisoning deaths in the US
 It is colorless, odorless, and tasteless
 CO is a byproduct of combustion, therefore at-risk
individuals include:
 Boats, Bar-B-Que inside a closed garage
 Sleeping inside a running car
 Faulty furnace, wood stove, or water heater

Cyanide Poisoning
Signs and Symptoms
 Ingestion or absorption  Large, concentrated/intense
exposure
 Dizziness

 Headache
 Loss of consciousness
 Nausea and vomiting
 Low blood pressure
 Rapid breathing
 Lung injury
 Rapid heart rate

 Restlessness
leading to death
 Weakness
 Slow heart rate
Emergency Medical Response
Care for Carbon Monoxide Poisoning
 Ensure that EMRs are properly outfitted for safety
 Remove the patient from the situation as quickly
as possible
 Alert ER staff and physicians about the suspicion
of CO poisoning
 Inform the patient that he or she may have a
blood test to confirm diagnosis
 Monitor and treat everyone in the area
 Administer emergency oxygen
 Home CO detector
Emergency Medical Response
Care for Cyanide Poisoning
 Observe for signs and symptoms of cyanide
poisoning
 Seek medical attention immediately
 Seek fresh air or rest in a half-upright position
 Administer emergency oxygen
 Wear protective clothing
 Rinse eyes with plenty of water
 Read CO and cyanide Enrichment pages 368-371

Enrichment
Administering Activated Charcoal
 Give within 1 hour of ingestion (ideally) only if directed
by medical control or the PCC and the patient is fully
conscious and alert
 Not for patients who have overdosed on cyanide or
swallowed acids or alkalis
 Mix it thoroughly with water and give through a straw or
use an opaque container
 Dosage:
• 1 g per kilogram of patient’s weight
