Burns: Differences and G6PD Compatibility with Creams - Pharmacology

More Info

Burns and scalds are terms often used interchangeably, but they refer to different types of injuries. Burns are typically caused by exposure to heat, chemicals, electricity, or radiation, while scalds are specifically caused by hot liquids or steam. Both injuries can result in damage to the skin and underlying tissues, but the mechanism of injury differs.
Burns are classified into degrees based on the severity of the tissue damage:
1. First-degree burns affect only the outer layer of skin (epidermis), causing redness and minor pain.

2. Second-degree burns extend into the second layer of skin (dermis), resulting in blisters, swelling, and more intense pain.

3. Third-degree burns penetrate through all layers of skin, potentially affecting underlying tissues, and may appear white, charred, or leathery. These burns can be painless due to nerve damage.

4. Fourth-degree burns go even deeper, affecting muscles, tendons, and bones.

Scalds, being a type of burn, can also be classified similarly based on the depth of skin damage.
Regarding the use of topical creams like 康膚乳膏 (Kangfu Cream), which contains silver sulfadiazine, it is essential to consider the implications for individuals with G6PD deficiency. G6PD deficiency is a genetic condition that affects the enzyme responsible for protecting red blood cells from damage. Certain medications, including sulfonamides (like silver sulfadiazine), can trigger hemolytic anemia in these patients.
In the case of G6PD deficiency, it is crucial to avoid medications that are known to cause oxidative stress. Silver sulfadiazine has been documented to cause acute hemolytic anemia in G6PD-deficient individuals, as highlighted in a case report where a young man developed this condition after using the cream for burn treatment. Therefore, while the cream may be effective for treating burns and scalds, its use in G6PD-deficient patients is contraindicated due to the risk of serious side effects.

For individuals with G6PD deficiency, alternative treatments for burns and scalds should be considered. These may include:
1. Gentle cleansing of the affected area with mild soap and water.

2. Application of non-irritating, non-sulfamide creams or ointments that promote healing and prevent infection, such as aloe vera gel or specialized burn ointments that do not contain harmful ingredients.

3. Pain management through over-the-counter medications that are safe for G6PD patients, such as acetaminophen.

4. Monitoring for signs of infection and seeking medical attention if the burn worsens or does not heal properly.

In conclusion, while burns and scalds are related, they differ in their causes and treatment approaches. For G6PD-deficient individuals, it is vital to avoid using silver sulfadiazine and seek safer alternatives for burn treatment. Always consult with a healthcare professional before using any medication or topical treatment, especially in the context of specific health conditions like G6PD deficiency.
