Burn and Scalds

Definition of Burns:

• Burns occur when heat energy transfers to the body’s tissues, damaging skin and underlying layers.
• Common sources: sun, fire, hot liquids, chemicals, or cold exposure.

Scalds:

• A scald is a burn from hot liquid or steam (e.g., hot water or spilled drinks).

Classification of Burns by Depth

1. Superficial Partial Thickness (First-Degree Burns):

• Affects only the outer skin layer (epidermis).
• Symptoms: Red, painful skin, slight swelling, no blisters.
• Healing: 3-6 days, with minor peeling.

1. Deep Partial Thickness (Second-Degree Burns):

• Affects both the epidermis and part of the dermis.
• Symptoms: Redness, blisters, severe pain, and swelling.
• Healing: 1-3 weeks, cause scarring.

1. Full Thickness (Third-Degree Burns):

• Destroys the epidermis, dermis, and deeper layers.
• Symptoms: Dry, white, leathery, or charred skin, often painless due to nerve damage.
• Treatment often requires skin grafts.

1. Fourth-Degree Burns:

• Extends to muscles, tendons, and bones.
• Symptoms: Blackened, deeply charred areas with no sensation.
• Often requires amputation.

First Aid for Burns

For Minor Burns (First-Degree):

1. Cool the burn under cool (not ice) water for 5 minutes.
2. Cover with a clean, non-adhesive bandage.
3. Use over-the-counter pain relievers if needed.
4. Protect from pressure and friction.

For Severe Burns (Second & Third-Degree):

1. Do not remove burnt clothing.
2. Make sure the victim is breathing; start CPR if necessary.
3. Cover the burn with a cool, moist bandage.
4. Elevate the burned area to reduce swelling.
5. Prevent shock by laying the victim down and covering them.

Things to Avoid:

• Do not apply ointments, ice, or home remedies.
• Avoid breaking blisters or disturbing dead skin.
• Do not immerse severe burns in cold water (can cause shock).

Poisoning

Poisoning and Its Types

Definition and Introduction:
Poisons or toxins are harmful substances. When ingested, inhaled, injected, or absorbed through the skin, they can harm or even kill a person. Poisoning occurs accidentally or with intent, affecting cellular metabolism, damaging tissues, or disrupting normal bodily functions. Many toxins also impair mental status, making it hard to collect a clear history from patients.

Types of Poisoning

1. Poisoning by Swallowing:

• Occurs through ingestion of household products, medication overdoses, or toxic plants.
• Examples: Chemicals like bleach, fungi, and poisonous plants like foxgloves.
• Medications: Overdose of prescription or over-the-counter drugs.

1. Poisoning by Gases:

• Exposure to toxic fumes from sources like charcoal stoves, vehicle exhaust, or gas leaks.
• Effects: Asphyxia, unconsciousness, and difficulty breathing.

1. Poisoning by Injection:

• Results from injection of toxic substances or venom from animal bites or stings (e.g., snake bites or insect stings).
• Effects: Choking, coma, and danger to life.

1. Poisoning by Skin Absorption:

• Hazardous chemicals absorbed through the skin can cause irritation or internal damage.
• Examples: Exposure to spilled chemicals.

Food Poisoning

Food poisoning happens when contaminated food is consumed, often due to bacteria (Staphylococcus, E. coli), viruses, or parasites.

Signs and Symptoms:

• Abdominal cramps, diarrhea
• Fever (38°C or above)
• Nausea, vomiting, weakness
• Headache, loss of appetite

First Aid Management:

1. Rest the victim and guarantee hydration.
2. If vomiting, give small sips of water to avoid dehydration.
3. Replace fluids and electrolytes lost through diarrhea.
4. Gradually reintroduce bland foods like bread or rice.
5. Avoid alcohol, caffeine, and fizzy drinks.
6. Do not use anti-diarrheal medications.
7. Keep samples of vomited material for emergency services.

Carbon Monoxide Poisoning

Carbon monoxide (CO) is a colorless, odorless, and tasteless poisonous gas. It binds with hemoglobin in the blood, forming carboxyhemoglobin, which limits oxygen delivery to tissues.

Signs and Symptoms:

• Difficulty breathing, headache
• Nausea, vomiting, dizziness
• Fatigue, confusion, hallucinations
• Weakness, altered consciousness

First Aid Management:

1. Move the casualty to fresh air right away.
2. Call emergency medical services.
3. If the person stops breathing, start CPR.
4. Check vital signs and make sure the person is responsive.

Drugs and Alcohol Poisoning

An overdose occurs when too much of a drug or substance is consumed. Alcohol poisoning happens when there is an excessive amount of alcohol in the bloodstream.

Signs and Symptoms:

• Drowsiness, confusion, hallucinations
• Breathing difficulty, seizures
• Nausea, vomiting, altered mental state
• Pale, cold skin

First Aid Management:

1. Assess the patient’s consciousness. If unconscious, turn them onto their side.
2. Reassure and calm the patient.
3. Do not leave the person alone, especially if they are agitated.
4. Ask what substance was consumed, how much, and when.
5. Do not induce vomiting or give food or drinks.
6. Activated charcoal be used to prevent drug absorption.
7. Check vital signs and seek emergency help if needed.

Poisoning requires quick recognition and immediate action. Always seek professional medical assistance when dealing with suspected poisoning cases.

Bites and Stings

Frostbite And Effects of Heat

Frostbite

Frostbite is the freezing of the skin and underlying tissues due to exposure to cold temperatures. It commonly affects areas like the hands, feet, nose, and ears. Frostbite results from decreased blood flow and heat delivery to body tissues. This leads to ice crystal formation that can cause tissue damage. The damage can include loss of sensation. In severe cases, it can even cause gangrene.

Signs and Symptoms of Frostbite:

• Pins and needles sensation, followed by numbness
• Throbbing or aching in the affected area
• Hard, pale, cold, and numb skin
• Burning sensation and swelling
• Blisters that may form thick, black scabs
• Damage to deep structures like tendons, muscles, and bones

First Aid for Frostbite:

1. Move the person to a warmer place and protect them from the cold.
2. Remove any constricting jewelry or wet clothing.
3. Warm the affected areas with body heat (hands in armpits, etc.).
4. Avoid rubbing the skin and tissues to prevent further damage.
5. Rewarm the area by soaking it in warm water (104° to 108°F) for 20-30 minutes.
6. Avoid direct heat sources, as they can worsen the injury.
7. After rewarming, gently bandage the frostbitten area, keeping fingers and toes separated.
8. Elevate the affected limb and seek medical attention for advanced cases.

Heat-Related Emergencies

Heatstroke

Heatstroke is a severe, life-threatening condition. It is caused by prolonged exposure to high temperatures. In this condition, the body’s ability to regulate temperature fails. Body temperatures rise above 104°F (40°C), and without immediate intervention, it can cause brain damage or death.

Signs and Symptoms of Heatstroke:

• Body temperature above 104°F
• Hot, flushed, dry skin
• Headache, dizziness, confusion
• Rapid, full, bounding pulse
• Hallucinations or seizures
• Loss of consciousness

First Aid for Heatstroke:

1. Move the person to a cool area and loosen clothing.
2. Rapidly cool the person using water sprays, cool compresses, or a cold shower.
3. Apply ice packs to armpits and groin.
4. Watch the person’s vital signs and seek emergency medical help.
5. If unconscious but breathing, place the person in the recovery position.
6. Do CPR if breathing stops.
