Basics Of Burn Treatment - 1st, 2nd and 3rd Degree
Six Echo
Overview
This video explains the basics of burn treatment, focusing on classifying burns by depth and type, and outlining appropriate first aid and medical management. It details the three main layers of skin (epidermis, dermis, hypodermis) and how burn depth relates to these layers, using terms like superficial, partial thickness, and full thickness. The video also covers various burn causes (thermal, chemical, electrical, etc.), factors influencing severity beyond depth (location, body surface area), and specific treatment steps for different burn degrees, emphasizing the importance of stopping the burning process, preventing infection, maintaining temperature regulation, and seeking professional medical help.

Chapters
- Burns damage skin layers: epidermis (outer), dermis (middle, thickest), and hypodermis (subcutaneous).
- Burn severity is classified by the depth of skin layers involved.
- Older terms (1st, 2nd, 3rd degree) are being replaced by superficial, partial thickness, and full thickness classifications.
- Fourth-degree burns extend beyond the skin into underlying tissues like muscle and bone.
Knowing the skin layers is crucial because the depth of a burn directly determines its severity, potential complications, and the appropriate treatment approach.
The epidermis is the outermost layer, the dermis is beneath it and is the thickest, and the hypodermis is below the dermis.
- Burns can be caused by various sources: thermal (heat), chemical, electrical, friction, cold, and radiation (like UV).
- Severity is influenced not only by burn depth but also by location (e.g., hands, airway, joints are critical), and the percentage of body surface area affected.
- Burns to sensitive areas like hands, feet, airway, or genitalia require more urgent and careful treatment due to functional and aesthetic implications.
- Extensive burns, even if partial thickness, can be more critical than smaller full-thickness burns due to the large surface area affected.
Understanding the diverse causes and additional severity factors helps in accurately assessing a burn's immediate and long-term impact on a patient.
A burn on the palm of the hand is more critical than a similar depth burn on the upper arm because the hand is vital for dexterity and daily function.
- Characterized by redness, pain, and intact skin without blisters.
- Affects only the epidermis.
- Low risk of infection as the skin barrier remains largely intact.
- Treatment involves cooling the burn with clean water for 5-10 minutes to stop the burning process and covering with dry gauze.
Prompt and correct treatment of superficial burns prevents further damage and reduces the risk of complications like infection.
Touching a hot stove briefly results in a bright red, painful area on the skin without any blisters.
- Involves the epidermis and part of the dermis.
- Key sign is the presence of blisters.
- Treatment is similar to first-degree burns: stop the burning, cool the area, and cover with a dry, sterile dressing.
- Blisters should not be popped to maintain the skin's protective barrier and prevent infection.
Proper management of partial thickness burns, especially avoiding popping blisters, is essential to prevent infection and promote healing.
A burn from scalding water that causes redness, significant pain, and the formation of fluid-filled blisters.
- Damage extends through the entire dermis (third degree) or into deeper tissues like muscle and bone (fourth degree).
- Skin may appear white, charred, or leathery; may be less painful initially due to nerve damage.
- High risk of infection due to the open wound.
- Immediate priority is patient assessment (ABCs), stopping the burning process, and covering with clean, dry dressings.
- Avoid applying gels or ointments directly into deep wounds; use sterile saline for flushing if available.
Full thickness burns are critical medical emergencies requiring immediate professional attention due to severe tissue damage, infection risk, and potential systemic effects.
A burn resulting from prolonged contact with fire that destroys all skin layers, potentially exposing underlying fat or muscle.
- Prioritize life threats: assess airway, breathing, and circulation (ABCs) before focusing solely on the burn.
- Monitor for airway compromise, especially with burns to the face or inhalation injuries (look for soot, stridor).
- Assess breathing for adequacy and potential complications like carbon monoxide poisoning or constricting circumferential burns.
- Circumferential burns around the chest can impair breathing; burns around extremities can cause compartment syndrome, potentially requiring escarotomy.
Systemic assessment and management of life-threatening issues are paramount in severe burn cases, as these can be more immediately fatal than the burn itself.
A patient who was in a house fire needs their airway checked for smoke inhalation before treating the burns on their arms.
- Stop the burning process completely and remove constricting items (rings, watches) before swelling occurs.
- Keep the burn clean and covered with non-stick sterile dressings or clean plastic wrap (like saran wrap), ensuring it doesn't act as a tourniquet.
- Maintain patient warmth to prevent hypothermia, as large burns impair temperature regulation.
- Fluid resuscitation (IV fluids like Lactated Ringer's) is vital to replace lost fluids.
- Antibiotics are often necessary to prevent or treat infection due to the compromised skin barrier.
Comprehensive management, including fluid replacement, infection prevention, and temperature control, is critical for survival and recovery from severe burns.
Applying saran wrap loosely over a large burn on a leg, then securing it with gauze, helps keep it clean and prevents it from becoming a constricting band as swelling occurs.
Key takeaways
- Burns are classified by depth (superficial, partial, full thickness) based on which skin layers are damaged.
- Beyond depth, burn severity is influenced by type (thermal, chemical, etc.), location, and the total body surface area affected.
- The primary goals in burn treatment are to stop the burning process, prevent infection, and maintain the patient's temperature.
- For severe burns, always prioritize a full patient assessment, including airway, breathing, and circulation, before focusing solely on the burn injury.
- Protecting the compromised skin barrier is key to preventing infection, often achieved with clean, non-stick dressings or plastic wrap.
- Severe burns lead to significant fluid loss and impaired temperature regulation, necessitating fluid resuscitation and keeping the patient warm.
- Never pop blisters on partial thickness burns, as they provide a natural barrier against infection.
