What type of dressings should not be used with steam sterilization?

• A. Hydrogel dressings
• B. Compressed cotton dressings
• C. Hydrophilic gauze
• D. Standard paper towels

Answer: (A)

Hydrogel dressings should not be used with steam sterilization due to their composition, which includes a significant amount of water. When exposed to steam during the sterilization process, the moisture in hydrogel dressings can lead to inadequate sterilization conditions. This occurs because steam sterilization relies on the effective penetration of steam and heat to achieve sterilization, and excessive moisture from hydrogel dressings can interfere with the process, potentially resulting in insufficient sterilant contact with microorganisms.

Other types of dressings, such as compressed cotton dressings or hydrophilic gauze, are more compatible with steam sterilization since they generally allow for appropriate steam contact and heat penetration. Standard paper towels, while not typically used for dressing wounds, can be sterilized in steam as they don’t retain excessive moisture that would hinder the sterilization process.
