To help maintain an airtight seal for negative-pressure wound therapy, which action is recommended?

• A. Retaining hair around the wound
• B. Using a skin barrier around the wound
• C. Drying around the wound thoroughly
• D. Applying adhesive remover to the wound edges

Answer: (B)

Creating and maintaining an airtight seal in negative-pressure wound therapy hinges on preparing the periwound area so the adhesive drape can stick securely. Using a skin barrier around the wound provides a smooth, protective surface that helps the drape adhere to irregular contours and moist skin, reducing leakage and protecting the skin from adhesive irritation.

Leaving hair around the wound would interfere with a tight seal, making leaks more likely. Drying the area, while helpful, isn’t the main method for ensuring an airtight seal in NPWT. Applying adhesive remover to the wound edges would weaken the bond between skin and drape, compromising the seal.
