Burn Severity Classification Chart
All burn depths compared side-by-side — appearance, sensation, blistering, healing potential, TBSA counting, treatment priorities, and NCLEX memory aids for each classification.
Educational use only. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.
Key rule: Superficial (1st degree) burns are NEVER counted in TBSA for Parkland formula calculation.
| Feature | Superficial (1st degree) | Superficial Partial (2nd superficial) | Deep Partial (2nd deep) | Full Thickness (3rd degree) | Deep Full Thickness (4th degree) |
|---|---|---|---|---|---|
| Old terminology | 1st degree | 2nd degree (superficial) | 2nd degree (deep) | 3rd degree | 4th degree |
| Tissue layers involved | Epidermis only | Epidermis + superficial dermis (papillary layer) | Epidermis + deep dermis (reticular layer — most dermis destroyed) | Epidermis + entire dermis destroyed | Full dermis + subcutaneous tissue, muscle, bone, or tendon |
| Appearance | Erythema (redness), dry, no blisters | Moist, pink/red, blisters present, weeping | Pale/mottled/red, blisters may be present, less moist | Leathery, waxy, white/brown/black, dry, eschar formation | Charred, black, deep tissue (muscle/bone) may be visible |
| Sensation (pain) | Painful (intact nerve endings) | Very painful — extremely sensitive (exposed nerve endings) | Reduced sensation; painful to pressure (fewer functional nerves remain) | Painless at burn site (all nerve endings destroyed). Perimeter/edges may be painful. | No pain (complete nerve destruction) |
| Blisters | No | YES — hallmark of partial-thickness burn | May be present (often ruptured or absent) | No (eschar replaces dermis; no fluid accumulation layer) | No |
| Color | Red/pink | Bright red/pink, moist | Pale, mottled, dull red | White, tan, brown, or black (charred) | Black (charred) |
| Capillary refill | Brisk (< 2 sec) — blanches with pressure | Present | Sluggish or absent | Absent (non-blanching, no perfusion through burned tissue) | Absent |
| Healing potential | Heals in 3–5 days; no scar | Heals in 7–21 days; minimal scarring if uninfected | Heals in 21–35 days; significant scarring; may convert to full-thickness; often requires grafting | Does NOT heal without skin grafting (no epithelial cells remain for re-epithelialization) | Requires amputation or complex reconstruction; does not heal spontaneously |
| TBSA counted? | NO — superficial burns excluded from TBSA | YES | YES | YES | YES |
| Treatment | Cool water irrigation, moisturizer, analgesics, sun protection | Non-adherent dressings (Mepitel, Mepilex Ag), silver sulfadiazine, analgesia; blister management per protocol; strict infection prevention | As superficial partial-thickness; closely monitor for conversion; skin grafting often required; contracture prevention | Fluid resuscitation (Parkland); escharotomy if circumferential; skin grafting required; tetanus prophylaxis; nutritional support | Emergent surgical consultation; amputation often required; ICU-level care; reconstructive surgery |
| Nursing priorities | Pain management; wound care teaching; return precautions (infection signs) | Pain management (very painful for dressing changes); infection prevention; adherence monitoring; patient teaching on blister care | Circulatory monitoring; infection prevention; grafting preparation; contracture prevention (positioning, splinting, physical therapy referral) | Airway (inhalation injury); fluid resuscitation (hourly UO monitoring); escharotomy monitoring; wound care; infection control; nutritional support | As full-thickness plus: amputation preparation and psychological support; extensive wound management |
| NCLEX Memory Aid | Red + Dry + No Blisters + Painful = 1st degree → NOT in TBSA | Blisters + Moist + Very Painful = 2nd superficial | Blisters ± + Pale + Reduced sensation = 2nd deep → may need graft | Leathery/Waxy + DRY + PAINLESS at site = 3rd degree → ALWAYS needs graft | Charred + Structural damage = 4th degree → Surgical emergency |
TBSA Summary
NOT counted: Superficial (1st degree) — only epidermis, no fluid compartment shift
COUNTED: All partial-thickness and full-thickness burns
Rule of Nines (adults): Head 9%, Each Arm 9%, Anterior Trunk 18%, Posterior Trunk 18%, Each Leg 18%, Perineum 1%
Parkland formula: 4 mL × kg × %TBSA = LR in first 24h (give ½ in first 8h from time of injury)
Grafting Requirements
No graft needed: Superficial (1st), Superficial Partial-Thickness (2nd superficial) — heals by re-epithelialization from remaining skin appendages
May need graft: Deep Partial-Thickness (2nd deep) — depends on depth and infection
ALWAYS needs graft: Full-Thickness (3rd), Deep Full-Thickness (4th) — no remaining epithelial cells for spontaneous healing
NCLEX High-Yield Burn Facts
Full-thickness burns are PAINLESS at the burn center — no nerve endings. Do not expect pain complaint FROM the burn site (perimeter/edges may still hurt).
Superficial partial-thickness = most painful burn type — exposed nerve endings to air → severe pain.
Blisters = partial-thickness. No blisters: superficial (1st) or full-thickness (3rd).
Do NOT apply ice to any burn — causes vasoconstriction → worsens tissue damage and risks hypothermia.
Do NOT pop blisters — intact blisters are sterile barriers against infection.
Inhalation injury = early intubation. Airway edema progresses over hours — secure the airway before it swells shut.
