POISONING
Poisoning is the harmful effect that occurs when a toxic substance is:
Swallowed Inhaled Comes in contact with the skin, eyes, or mucous membranes, such as those of the mouth or nose.
Poisoning is the most common cause of nonfatal accidents in the home.
Common source of poisonings
Drugs Gases, Household products, Plants, Industrial chemicals, foods (certain species of
mushrooms and fish).
However, almost any substance ingested in sufficiently large
quantities can be toxic.
Vulnerability to accidental poisoning
Young children,Older people, Hospitalized people (from drug
errors)
Industrial workers (from exposure to toxic chemicals)
Poisoning may also be a deliberate attempt to commit murder or suicide (taking more than one drug or consume alcohol)
(at home, often from confusion about their
drugs )
The damage caused by poisoning depends on :
1.Poison: Type, Potency, & Amount taken.
2.Patient: Age & Health
Some poisons are: Not very potent and cause
problems only with prolonged exposure or repeated ingestion of large amounts.
So potent that just a drop on the skin can cause severe damage.
Some poisons produce symptoms within seconds, whereas others produce symptoms only after hours or even days.
Some poisons produce few obvious symptoms until they have damaged vital organs (e.g. kidneys or liver).

Plants Poisoning
1-Toxicity by eating excessive amounts of some plants:
Guava seeds, spine fig seeds or similar plants
Some cooked vegetables,e.g. Molokheya.
Spices
GIT upset, colic pain, vomiting and constipation in individuals with irritable colon syndrome.Diarrhea
GIT troubles
Nutmeg(type of spice with narcotic action)
potent hypnotic & hallucinating effect, severe headache, dizziness, nausea.
2- Toxicity by drinking excessive amounts of beverages
Excessive drinking of Coffee, or Tea may:
blood pressure & irregular heart beats.
CNS side effects (insomnia & nervousness).
3- Capsicum: - Inhaled irritation of mucus
membrane ------- oropharyngeal edema & suffocation.
- In contact with skin skin irritation & itching.
Plants Poisoning
3- Medicinal plants:Some medicinal plants can cause
serious toxicity when prescribed by non-professional people
e.g.• Senna plant (laxative) • Caster oil (laxative) • Datura (hallucination and
psychological disorders may occur).
Plants Poisoning
4- Ornamental plants and garden flowers:
Some of these plants if eaten by children or come in contact with skin or mucous membrane may cause serious poisoning e.g.
Lily (contains cardiac glycosides)
Jessamine (if digested nervous
troubles)
Narcissus ( dermal irritation).
Plants Poisoning
First aid management:
Identifying the poison is crucial to successful treatment.Labels on bottles and other information from the person, family members, coworkers or the victim (if he can talk) enables the doctor or the aider to identify poisons.
Try to treat the apparent symptoms such as fever, diarrhea, or stomach pain till medical help arrives.
Plants Poisoning
In unconscious patients:
breathing normally place him in the recovery position.
snoring of gurgling open the air way by putting the tongue forward.
not breathing normally mouth-to-mouth breathing & chest compression till normal breathing is retained.
Plants Poisoning
If he is:
Many people who have been poisoned must be hospitalized.
The principles for the treatment of all poisoning are the same:
- Prevent additional absorption - Increase elimination of the poison
- Give specific antidotes, if available
- Prevent re-exposure.
With prompt medical care, most people recover fully.
Plants Poisoning
Chemical Poisoning
Chemical poisoning occurs when toxic substances and solvents come in contact or enter the body and negatively affect organ function.
Caused by the ingestion, inhalation or absorption (through the skin) of harmful substances by the body.
Chemicals that can cause poisoning include:
acids, alkalis, ammonia, chlorine disinfectants, heavy metals herbicides, insecticides and
petroleum products.
When these substances are absorbed by the body, damage to the internal organs, especially the liver, may occur.
First aid for chemical accidents:
Give alarm to others in the area so that no one else is harmed.
Protect yourself.
Terminate the victim exposure by removing him from the contaminated area
Notify emergency services
Support the respiration and circulation of the victim.
Calm and comfort the victim.
I- Inhalation:Inhalation of irritating vapors or fumes as concentrated acids (HCl, acetic acid), ammonia, chlorine, etc
Symptoms: Irritation of mucous membrane
(nose, mouth, eyes and throat) Excessive discharge from eyes
(tears) and nose, coughing and sneezing.
Chest pain, difficulty in breathing. Headache, nausea and muscle
weakness In some cases convulsions, loss of
consciousness and even death may occur.
First aid:
1-Remove the victim from the contaminated area, and try not to harm yourself.
2- Call the emergency
3- Try to move him to an aerated place, loosen his collar and belt.
.……Inhalation
5- Check the pulse, if no pulse, begin CPR.
6- Keep the victim warm (cover with a blanket).
4- Open the airway, if no breathing, begin rescue breathing (mouth-mouth breathing).
II- Ingestion:
Symptoms of acute poisoning:
Irritation & swelling of lips, mouth & throat.
Pain in swallowing with intense thirst.
Nausea & vomiting.
Risk of stomach perforation.
Difficulty in breathing.
In some case, convulsions, coma or even death may occur.
Stomach
Check the airway for obstruction
Loosen tight clothing (collar and belt).
If the victim is conscious, give him cold water and let him rinse his mouth and spit out several times. He can also drink cold water to dilute the effect of the poison.
The main goal is to dilute the ingested poison and prevent further injury caused by vomiting.
First aid:….. Ingestion
If the victim is not breathing or the pulse is irregular start rescue breathing and CPR.
If the victim is unconscious and breathing normally put him in the recovery position and cover him with a blanket to keep him warm.
….. Ingestion
DO NOT:
Give an unconscious victim anything to drink or eat
Use any alkali to neutralize ingested acid (worsen the condition)
Give the victim oil to dilute the poison
Give sodium bicarbonate or any carbonated drinks.
….. Ingestion
III- Skin contact:
Symptoms:Burning sensation, redness,
swelling with severe pain, tingling sensation, painful blisters
First aid:
Our goal is to remove the chemical in contact with the skin as quickly as possible.
Remove the victim from the source of contamination.
Remove clothing, shoes, or jewelry from the affected area as quickly as possible.
Rinse the affected area with water for at least 15 minutes.
In case of severe injury or burn call the emergency help or transport him to the hospital.
If the patient is in state of shock cover him and elevate his legs.
DO NOT use oil or hot water to dilute the chemical in contact with the skin.
……. Skin contact
Let the patient sit with his head tilted to the back and hold the eyes open and pour water slowly over the eyeball at the inner corners letting the water run out from the outer corners.
IV- Splashing of eye:
Remove the victim from the source of contamination.
Immediately rinse the eyes with clean water for at least 15 minutes
It is better to hospitalize even if the victim doesn’t feel more pain.
DO NOT: let the victim rub his
eyes. keep his eyes tightly
closed. put any oil or ointment
in his eyes. use hot water.
