What type of dressing can be used to absorb excessive drainage in peritubular breakdown?

1. Hydrocolloid dressing

2. Calcium alginate

3. Foam dressing

4. Gauze dressing

The correct answer is: Calcium alginate

Calcium alginate dressings are particularly effective in managing wounds with excessive drainage, such as in cases of peritubular breakdown. These dressings are made from natural alginate fibers derived from seaweed, which have the unique ability to absorb a significant amount of exudate while maintaining a moist wound environment that promotes healing. They turn into a gel-like consistency when they come into contact with fluid, helping to protect the underlying tissue and can also aid in autolytic debridement. This characteristic makes calcium alginate an ideal choice for wounds that have high levels of drainage, as it not only absorbs moisture effectively but also minimizes the risk of wound maceration. Furthermore, calcium alginate dressings are known for their biocompatibility, which means they are well-tolerated by the body and minimize irritation. While hydrocolloid dressings can also absorb some exudate, they are more suitable for low to moderate drainage levels and can become saturated and ineffective in the presence of excessive fluid. Foam dressings have good absorbency but may not provide the same gel-forming properties that alginate dressings do when faced with high levels of drainage. Gauze dressings are less effective at maintaining a moist environment and may require frequent
