In treating diaper dermatitis, what product is typically used for severe denudation?

  1. Petroleum jelly

  2. Hydrocortisone cream

  3. Carboxymethylcellulose/petrolatum/zinc oxide

  4. Isopropyl alcohol

The correct answer is: Carboxymethylcellulose/petrolatum/zinc oxide

In the treatment of diaper dermatitis, especially in cases of severe denudation, the typical choice is a formulation that combines carboxymethylcellulose, petrolatum, and zinc oxide. This combination is effective because: - Carboxymethylcellulose acts as a protective barrier that helps to maintain moisture in the skin while preventing further irritation from urine and feces. - Petrolatum provides a thick, occlusive barrier that protects the skin from external irritants and helps to heal the skin by creating a moist wound environment. - Zinc oxide is well-known for its soothing properties and its ability to protect the skin from moisture and irritation, thereby enhancing the healing process. Together, these ingredients not only promote healing but also create an effective barrier that prevents further skin breakdown, which is particularly important in cases of severe dermatitis where the skin barrier is compromised. This makes the combination the most suitable option for managing severe diaper dermatitis.
