Which dressing is recommended for absorbing drainage in peritubular breakdown?

1. Hydrocolloid

2. Calcium alginate

3. Polyurethane foam

4. Gauze

The correct answer is: Calcium alginate

The recommended dressing for absorbing drainage in peritubular breakdown is calcium alginate. This type of dressing is particularly suited for wounds with moderate to heavy exudate because it has excellent absorbent properties. Calcium alginate is derived from seaweed and forms a gel-like substance when it comes into contact with wound fluid, effectively managing moisture and maintaining a moist wound environment which is conducive to healing. In cases of peritubular breakdown, where the skin around a stoma or tube site may become irritated or compromised, effective drainage management is crucial. The gel formation aids in keeping the area moist while absorbing excess fluid, thus reducing the risk of further skin irritation or breakdown. While other options may have their uses, they may not be as effective in managing the specific needs of peritubular skin breakdown. Hydrocolloid dressings, for instance, are better suited for low to moderately exuding wounds and may not absorb heavier drainage adequately. Polyurethane foam dressings are also good for absorbing exudate but may not provide the same level of moisture management as calcium alginate dressings. Gauze can absorb drainage but does not maintain a moist environment as effectively and may require more frequent changes, which could lead to additional disruption of the healing process
