Xeroform Gauze: Graft Sites, Burns and Petrolatum Interfaces
Petrolatum gauze is one of the oldest wound interfaces still in daily use, and it survives because the problem it solves has not changed: a wound surface that must not be torn when the dressing comes off. What has changed is how many substitutes exist, and how easily a buyer can order the wrong one.
What exactly is Xeroform gauze?
Xeroform gauze is a fine-mesh gauze impregnated with petrolatum carrying bismuth tribromophenate. The petrolatum does the mechanical work: it forms a barrier between the fabric of the gauze and the wound surface, so the gauze lifts away instead of bonding. The bismuth salt is a mild antimicrobial agent that has been part of the formulation for as long as the dressing has existed.
It is supplied sterile, individually wrapped, in a narrow range of sizes, and it is intended as a single-use interface layer. It is not an absorbent dressing, it does not manage exudate on its own, and it is not a substitute for a cover.
Which sites call for a petrolatum interface?
| Clinical site | Why petrolatum gauze is chosen | Coverage required above it |
|---|---|---|
| Split-thickness graft donor site | The new epithelial surface must not be disturbed at the first change | Absorbent cover, changed while the gauze stays in place |
| Meshed graft or graft recipient bed | Keeps the graft surface from bonding to the cover | Absorbent cover with light fixation |
| Freshly debrided wound | Protects the new surface during the first days | Absorbent cover, then reassess |
| Superficial partial-thickness burn | Reduces adherence and pain at dressing change | Absorbent cover; escalation to silver if indicated |
| Surgical incision with fragile surrounding skin | Lifts without stripping peri-wound skin | Cover and fixation chosen for skin condition |
What sizes and formats are available?
Petrolatum gauze is sold as individually wrapped sterile sheets in narrow strip, small square and larger rectangle formats, and some suppliers offer rolls for larger surfaces. Two practical points drive the size decision. First, coverage is measured against the wound, not the anatomical region: the dressing must cover the wound bed with a small overlap, and coverage should be achieved by choosing a larger sheet rather than by layering. Second, the size grid differs between manufacturers by a centimetre or more, so a facility that switches supplier without checking the grid can end up with a dressing that no longer covers the wound it was ordered for.
What should a purchaser compare before substituting?
Four checks cover most substitutions. The petrolatum loading, because a lighter coat dries out sooner on a long case. The mesh construction, because a coarser mesh handles tension differently on a graft. The antimicrobial agent, since bismuth tribromophenate is part of the Xeroform formulation and not part of a plain petrolatum dressing. And the packaging format, because a dressing that is supplied non-sterile cannot be used as a sterile interface layer regardless of price.
How does it fit with the rest of the dressing stack?
A petrolatum interface only works as part of a stack, and the stack is what a facility actually reorders. Petrolatum gauze is the interface layer for wounds that must not be disturbed, cloth tape is the usual fixation where the dressing has to hold under movement, transparent tape lets a graft site be checked without lifting the dressing, and wound closure strips cover the small superficial closures that do not need a petrolatum interface at all. Where a facility also sterilises the scissors and bowls that open and apply the mesh, a five-pack starter trial of its biological indicators covers the spore tests that release those loads.

Frequently Asked Questions
What is Xeroform gauze used for?
It is a petrolatum-impregnated gauze used as a non-adherent interface layer on sites where the wound bed must not be disturbed: donor and graft sites, freshly debrided wounds, burn surfaces and some surgical incisions. The petrolatum keeps the gauze from bonding, so the dressing lifts without tearing the surface underneath.
Is Xeroform the same as Adaptic?
No, although both are petrolatum-impregnated dressings. Xeroform carries bismuth tribromophenate in the petrolatum and is supplied as a gauze with a defined mesh. Adaptic-type dressings are petrolatum-impregnated cellulose acetate mesh. Both act as a contact layer, but the products are not interchangeable size for size in every protocol.
Can petrolatum gauze be cut to size?
Yes, with sterile scissors, and it is normal practice on irregular wounds. The cut edge is still petrolatum-coated, so it remains non-adherent. What should not be done is folding a petrolatum dressing into multiple layers to cover a larger wound - folds create pressure points and the layers slip against each other under a cover.
How often should petrolatum gauze be changed?
The dressing is not the absorbent layer, so the change interval follows the cover above it rather than the petrolatum gauze itself. Leaving the interface layer in place past the point where the petrolatum is exhausted is the usual reason it becomes stuck, and the fix is a cover that is checked at every round rather than a longer wear claim.
