Principles of burn care
Remove whatever is causing the burn and cool the burned flesh
Assess for red flags and refer on to further care
Limit pain, infection, and swelling, and promote healing
Types of burns
Thermal Burns: can be caused by solids, liquids and fire, touch something hot, including tear gas containers, steam
Chemical Burns: from chemical weapons and other chemicals; folks with asthma are especially vulnerable
Radiation Burns: sunburn. Wear oil-based sunscreen, cover all exposed skin with light cotton or other clothing, wear a hat with a wide brim
Electric Burns: taser injuries, lightning strike, electrocution (more on tasers tomorrow morning)
Friction Burn: blisters, high pressure water. Wear 2 pairs of socks with well broken-in shoes, as soon as you get a "hot spot" cover it with moleskin or duct tape
Classification of burns
Superficial Burns ("first-degree" burns): affect the top layer of skin only; skin is red and painful.
Partial-Thickness Burns ("second-degree" burns): affect the top 2 layers of skin; most notable by blisters (which may develop quickly but may take 24 hours to form), but also red, mottled, wet and painful
Full-Thickness Burns ("third-degree" burn): all 3 layers of skin affected and may have burns of muscles, bones and other deep tissues; leathery, dry, charred, gray, may not be painful b/c nerve endings have been destroyed BUT may be very painful b/c surrounded by partial-thickness and superficial burns.
Red Flags
Beware of airway or breathing problems: any facial burns or singing of facial hair, think AIRWAY problem (back to Initial Assessment)
Any circumferential burn (all the way around an arm, leg, or neck) should be sent on fast because burn could constrict and cut off circulation to the limb or compromise airway
Anyone with large burn, or smaller burn and other injuries, especially fractures, should be sent on fast
If it doesn't hurt, it may be really bad
For anything but the most minor burns, think shock
Anyone with a superficial burn larger than their palm should be sent on for more care
Anyone with a partial thickness burn larger than a quarter, or any full thickness burn, should be sent on for more treatment
Anyone with burns in sensitive places: face, hands, feet, genitals should be sent on
First aid: thermal burns
Burn care principles:
Cool with water 1
Pat dry
Apply honey (optional)
Apply dressing
Be sure to evaluate for other injuries as well
Stop the burning ASAP (goal: within 3 min.): extinguish any active burning; blow away powdered chemicals; pour water on burning clothing or skin
Remove clothing that comes off easily (but if cloth sticks, leave it there)
Remove any jewelry or other objects that could get stuck with swelling
Run the burn under cool tap water for 10 minutes (to cool down superficial AND deeper skin). If there's no running water and there is no open skin on the burn you can use a cloth or gauze wet with cool or room temperature water. To cool a cloth, get it wet and wave it around a bit, causing evaporation, cooling the cloth. Don't use ice, as it can freeze tissue. In cold weather beware of hypothermia
Pat the area dry
If you put any ointment, salve or oil on a burn that is not thoroughly cooled, it will trap the heat and increase the damage, so stop burning completely before applying any of the following:
Antibiotic ointment may help a little, but the effect is pretty small according to medical research. Biggest effect seems to come from providing a barrier to germs and keeping the dressing from sticking to the bur
Silvadene cream is good topically for burns
Honey does pretty much the same things antibiotic ointment does, and can improve healing time (grab honey packets from restaurants and coffee shops)
Aloe -- Aloe vera gel applied directly to superficial burns. Eases pain, fights infection and promotes healing. Gel squeezed fresh from the plant is best. You can also buy the prepared gel.
Chinese medicine burn remedy, applied topically, Jin Wan Hong (also known as Ching Wan Hung)
Put sterile dressing on (non-adherent if possible), separate skin folds (between fingers, toes, under breasts and any over-hanging skin, such as abdomen skin)
Remember to recommend tetanus precautions if none within 5 years
Blisters: do not break them unless you think they will inevitably break on their own. Dress with a blister pad, or "donut" made of moleskin, relieving pressure on the blister.
If you must break the blister:
Prep a needle or pin by holding over an open flame until it glows red
Remove carbon deposits on needle with alcohol pad
Break along base of blister by inserting sterilized needle, alongside the undamaged skin. Leave top of blister on.
Gently press on top of blister to push out liquid inside
Dress like an open wound
Pad pad pad with moleskin
Aftercare
Burn aftercare principles (1-2x/day):
Soak off dressing
Gently wash or soak burn wound
Apply honey (optional)
Apply new dressing
Notes:
Honey or ching wan hung placed on the skin decreases pain, promotes healing and prevents infection, aloe also an option for superficial burns only
A poultice of grated carrot, tofu, comfrey, or raw potato can decrease inflammation and promote healing: make a poultice by covering the burn area with the food listed above, then covering with a bandage. Leave on for 15 to 30 minutes. Repeat as needed
Move affected area gently through range of motion to prevent scar forming that limits motion
Nutrition is very important: for wound healing the body needs a good supply of vitamin C and zinc. vitamins A, E, the entire B vitamin family, calcium and magnesium also may help with healing from wounds and burns -- so eat well
Give "care for burn injuries" care sheet
- Any burns larger than 1-2 fingers or full-thickness, esp in wilderness, extended irrigation can = hypothermia, anything bigger than hand = medical care, don't put anything on for 3-4h to let it cool↩
