For a patient with ostomy-associated dermatitis, what is typically advised?

In cases of ostomy-associated dermatitis, the recommendation to apply hydrocortisone is based on its anti-inflammatory properties. Dermatitis, particularly in the context of an ostomy, often arises due to skin irritation from the adhesive used in ostomy appliances or from exposure to stool or urine, which can lead to redness, swelling, and discomfort.

Hydrocortisone can help alleviate these symptoms by reducing inflammation and providing relief from itching and irritation. The use of a low-potency topical corticosteroid like hydrocortisone is a common practice to manage localized skin irritations effectively.

While aloe vera gel is known for its soothing properties, it is more effective in treating minor burns and skin irritations, not specifically the inflammatory response seen in dermatitis. Witch hazel may provide astringent effects, but it's not typically indicated for managing inflammatory skin conditions like dermatitis. Topical antifungal agents are aimed at treating fungal infections rather than addressing the inflammation and irritation caused by dermatitis itself.

Thus, the application of hydrocortisone is the most suitable choice for managing ostomy-associated dermatitis, making it the advised course of action for patients dealing with this issue.
