Karaya-based barriers can be used if a patient reacts to hydrocolloids.

• A. True
• B. False
• C. Only with physician approval
• D. Not recommended

Answer: (A)

When a patient has a reaction to hydrocolloid adhesives, alternative barrier bases are used to protect the skin without triggering the same reaction. Karaya-based barriers use karaya gum to create a protective, adhesive skin barrier that does not rely on hydrocolloid polymers. This can reduce or eliminate contact dermatitis while still sealing around the stoma and shielding the peristomal skin from moisture and effluent. They’re a practical option for sensitive skin or hydrocolloid allergies, provided they’re compatible with the chosen ostomy system and the patient is properly assessed for any karaya sensitivity. In short, using a karaya-based barrier is an appropriate alternative when hydrocolloid products cause a reaction.
