What Is the Purpose of Xeroform Gauze? Clinical Applications
What is the purpose of Xeroform gauze?
The Quick Answer
Xeroform serves three key purposes: **1) Moisture maintenance** via petrolatum barrier preventing desiccation, **2) Non-adherence** protecting fragile granulation tissue during dressing changes, and **3) Mild antimicrobial action** from bismuth tribromophenate reducing bacterial load. Ideal for partial-thickness wounds, grafts, burns, and surgical sites requiring protected moist healing environments.
Why We Ask This
Clinicians sometimes substitute standard gauze for Xeroform to reduce costs, causing traumatic dressing removal that reopens healing tissue—particularly damaging for facial wounds where repeated trauma increases hypertrophic scarring risk.
The Practical Science
Xeroform's petrolatum saturation (30–40%) creates semi-occlusive conditions increasing epidermal hydration by 50% versus dry dressings. Bismuth tribromophenate disrupts bacterial cell walls without the cytotoxicity of iodine or silver in sensitive facial skin.
In Clinical Practice
In a Mohs surgery defect on the nose, Xeroform applied directly to the wound bed prevents graft disruption during changes while maintaining moisture critical for secondary intention healing—reducing scar width by 22% versus dry healing in comparative studies.
