Diagnosis it and give correct answers
Answer: Third degree (full thickness)
Here is the clinical reasoning:
Key findings in the scenario:
- White, firm area on the thigh
- Burnt clothing stuck to the wound
- No color change on pressure (blanching test negative)
Why Third Degree (Full Thickness)?
| Feature | 1st Degree | 2nd Degree | 3rd Degree | 4th Degree |
|---|---|---|---|---|
| Appearance | Red, dry | Red, blistered, moist | White/waxy/leathery | Charred, black |
| Sensation | Painful | Very painful | Painless (nerve destruction) | Painless |
| Blanching | Yes | Yes | No | No |
| Clothing stuck | No | Rarely | Yes (deep tissue damage) | Yes |
| Depth | Epidermis only | Partial dermis | Full dermis | Bone/muscle |
Clinical logic:
- The white, firm (leathery) appearance = coagulative necrosis of the full dermis
- No blanching on pressure = destroyed dermal capillaries no longer perfuse, so pressing cannot push blood out
- Clothing stuck to wound = deep enough damage for fabric to adhere to eschar
- All three together = classic third degree (full thickness) burn
Second degree burns would appear red/moist with blistering AND would blanch on pressure (viable capillaries still present). Fourth degree burns extend to muscle, bone, or tendon and typically appear charred/black.
