Study Notes

Evaluating and Treating Thermal Burns

The depth of a burn and the total body surface area (TBSA) it covers should be evaluated using the rule of nines and the rule of the hand.
Burns on the face, hands, feet, and genitals are the most severe, and circumferential burns are more severe than noncircumferential burns.
Superheated air can be absorbed by the upper respiratory tract, leading to swelling and airway restriction.
Consider respiratory involvement, preexisting medical problems, and age when determining burn severity.
First-degree burns exhibit redness, mild swelling, tenderness, and pain, and can be treated with cold water, ibuprofen, and elevation.
Small second-degree burns involve blisters, swelling, weeping of fluids, and severe pain, and should be treated with antibacterial ointment and a sterile dressing.
Large second-degree burns require cold application, monitoring for hypothermia, and immediate medical attention.
Third-degree burns feature dry, leathery, gray-colored, or charred skin and require covering with a sterile dressing and emergency medical care.
Later care for thermal burns includes changing dressings daily, watching for signs of infection, and following a physician's recommendations.
Chemical burns caused by acid or alkali substances result in pain, burning, breathing difficulty, and eye pain or vision change.
For chemical burns, brush off dry chemicals, flush with water for at least 20 minutes, and seek medical assistance.
Electrical burns can be arc burns, true electrical injuries, or thermal burns, and contact with outdoor power lines requires checking breathing and potentially starting CPR.
