Are the following true or false in adult patients with burns?

True / False

The anterior trunk is 18% of body surface area Correct

First degree burns have blisters Correct

The half life of carboxyhaemoglobin, in 100% oxygen, is 4-6 hours Correct

The area of a full thickness (third degree) burn is usually painless Correct

Acid burns should be neutralised with alkaline solution Correct

Explanation

Superficial (1st Degree)-epidermis

The skin will appear red without any blisters

The area will be painful and tender

Partial Thickness (2nd Degree)-epidermis and dermis

The skin will appear red or white with blisters

The area will be severely painful

Full Thickness (3rd Degree)-epidermis, dermis and may involve subcutaneous tissue (including hair follicles and sebaceous glands)

The area is painless but surrounding partial thickness will be painful

Complete (4th degree)-extend to include tedon, muscle, fascia and bone

Generation of toxic systemic reactions and sepsis

The half life of carboxyhaemoglobin in 100% oxygen is approximately 60-80 minutes, in air it is 4-6 hours.100% oxygen at hyperbaric pressure of 2.5 atmospheres reduces it to 15-23 minutes.

Chemical burns should be brushed off (if dry substance) and irrigated.

Using an alkaline substance to neutralise the acid may result in an exothermic reaction (generating heat), which could exacerbate the injury.
