Which type of ECM dressing requires moistening with saline if it becomes dry?

Collagen
OASIS
Acell
Alloderm

The correct answer is: OASIS

The correct choice highlights that OASIS, a type of extracellular matrix (ECM) dressing, requires moistening with saline if it becomes dry. OASIS dressings are derived from porcine intestinal submucosa, which provides a scaffold for cell infiltration and promotes the healing process. These dressings are designed to maintain a moist wound environment, which is crucial for optimal healing. When the dressing dries out, it can lose its effectiveness, and therefore, rehydrating it with saline helps to restore its properties and enhance its function in facilitating healing. Other types of ECM dressings like Collagen, Acell, and Alloderm have different properties and management techniques. While they each support healing in their respective ways, they do not require the same specific rehydration protocol as OASIS does when drying occurs. Only OASIS specifically necessitates this saline application to maintain moisture for effectiveness.
