The causes of burns range from chemical, gas and steam to thermal (heat), electrical and sunburn. But do you know how to identify the severity of a burn or how to treat it? Willem Stassen, an ER24 Critical Care paramedic, tells us more.
The three main types of burns:
Superficial burns (first degree): The burn affects only the epidermis (top layer of skin). Symptoms are some reddening, inflammation and pain, but no blistering.
Partial thickness burns (second degree): The burn reaches into the dermis (second layer of skin). Symptoms are redness, inflammation and pain, and fluid-filled blisters are present.
Full-thickness burns (third degree): The burn has gone through all the layers of skin. There is no reddening or swelling, and the skin appears greyish-white and leathery. There may also be some charring.
Treating a burn
The central part of a burn is normally the deepest and most severe. This central area is typically surrounded by less severe or more superficial burns. Cooling the burn prevents this central, deeper area from expanding and thereby worsening the burn. The first and most important thing is to cool the burn area down quickly, but how you do that depends on what caused the burn.
Thermal burns (caused by direct heat like fire, steam or oil): Place the affected area under cool running water from the tap until the area is cool to the touch. Don’t use ice (or iced water), as it could cause freeze-burn.
Electrical burns (caused by electric shock): If the live electrical device is still close by, make sure you turn the power off and safely remove it before treating the patient. The wound will have an entry and exit wound on the body, which will need treatment. The most important thing about electrical burns is that they can affect your heart rhythm and other organs in the body, often causing an irregular heartbeat, cardiac arrest or unconsciousness.
If the patient is unconscious and not breathing, start CPR immediately and call an ambulance on 084 124. If the patient is conscious, cool the entry and exit wounds and cover with a dry, clean dressing before seeking medical attention.
Chemical burns (caused by toxic or corrosive substances, usually at work): It’s vital to remember that different chemicals react differently to water and some are actually worsened by it. Therefore, water may not be a treatment or cooling option.
First, determine the source of the burn and call the Poisons Information Centre on 0861 555 777 for advice on what to do. If your skin has been burnt by a household chemical like bleach, pool acid or hair removal cream, rinse off under cold water and cover with a clean, dry dressing before seeking medical attention.
