What is a Scald?
A scald is a type of thermal injury caused by contact with hot liquids or steam. Unlike dry burns (from fire or hot objects), scalds result from moist heat, such as boiling water, hot beverages, steam from cooking, or hot oil. These injuries can range from mild redness to deep tissue damage, depending on the temperature of the liquid and the duration of contact.
Scalds are particularly common in the home, especially in the kitchen and bathroom. Children, the elderly, and people with reduced mobility are at higher risk, but anyone can be affected during daily routines.
How Does the Wound Happen?
Scald injuries typically occur through accidental exposure to hot liquids or steam. Common causes include:
- Spilling boiling water, hot tea, coffee, or soup
- Exposure to steam when opening lids of pots, kettles, or microwaved containers
- Hot oil splashes during cooking or frying
- Tipping over containers with hot liquids
- Contact with hot bath water, especially if water temperature isn’t checked before bathing
These injuries most often affect areas like the hands, forearms, chest, or abdomen, as these parts are usually exposed or used during cooking and carrying liquids. Scalds may cause pain, redness, swelling, and blisters, depending on severity.
What Happens If Not Treated?
If scalds are not properly treated, the injury can worsen and lead to complications such as:
- Infection: Broken or blistered skin is vulnerable to bacteria, which can lead to infection and delayed healing.
- Blistering and Peeling: Minor scalds can develop blisters that burst and leave raw, open skin if not protected.
- Skin Breakdown: Repeated exposure or lack of care can lead to skin thinning, cracking, or chronic wounds.
- Scarring: Moderate to severe scalds can leave lasting scars, especially if the wound becomes infected or re-injured.
- Pain and Swelling: Inflammation can increase over time, causing discomfort, reduced mobility, or difficulty using the affected area.
- Pigment Changes: Untreated scalds may cause darkening (hyperpigmentation) or lightening (hypopigmentation) of the skin.
- Tissue Damage: Deep scalds can damage layers below the skin, affecting nerves, muscles, or blood vessels in severe cases.
