Burn Classification

Question 1

Superficial Burn

Answer 1

A superficial burn involves only the outer epidermis. The involved sera may be red with slight edema. Healing occurs without peeing or evidence of scarring in two to five days.

Question 2

Superficial partial-thickness burns

Answer 2

A superficial partial-thickness burn involves the epidermis and the upper portion of the dermis. The involved area may be extremely painful and exhibit blisters. Healing occurs with minimal to no scarring in 5-21 days.

Question 3

Deep partial-thickness burns

Answer 3

A deep partial-thickness burn involves complete destruction of the epidermis and the majority of the dermis. The involved area may appear to be discolored with broken blisters and edema. Damage to nerve endings may result in only moderate levels of pain. Hypertrophic or keloid scarring may occur. In the absence of infection, healing will occur in 21-35 days.

Question 4

Full-Thickness Burn

Answer 4

A full-thickness burn involves complete destruction of the epidermis and dermis along with partial damage to the subcutaneous fat layer. The involved area typically presents with eschar formation and minimal pain. Patients with full-thickness burns require grafts and are susceptible to infection. Healing time varies significantly with smaller areas healing in a matter of weeks, with or without grafting, and larger areas requiring grafting and potentially months to heal.

Question 5

Subdermal Burns

Answer 5

A subdermal burn involves the complete destruction of the epidermis, dermis, and subcutaneous tissue. Subdermal burns may involve muscle and bone as a result, often require multiple surgical interventions and extensive healing time.
