Which type of dressing is considered an intermediate layer?

The intermediate layer of a dressing serves specific purposes, including managing exudate absorption, providing some padding, and sometimes serving as a barrier to bacteria. The 4 x 4 gauze sponges fit this description well. They are versatile and can absorb fluid from a wound while allowing some level of air exchange, making them appropriate for intermediate dressing layers.

In contrast, gauze rolls are often used as a primary layer or for wrapping, which doesn't fully categorize them as intermediate. Adhesive films are designed for their ability to provide a moisture barrier and protect against external contaminants but do not absorb exudate as an intermediate layer would. Non-adherent dressings primarily aim to prevent sticking to the wound and are often used on superficial or low-exudative wounds, not fulfilling the intermediate role effectively.

Thus, the 4 x 4 gauze sponges are the most suitable choice for an intermediate dressing layer, combining absorption with flexibility and breathability.
