Exuderm Odorshield Hydrocolloid

Exuderm OdorShield wound dressing, the first odor-control hydropolymer!

Exuderm odorshield sacral dressings are ideal for shallow sacral wounds with minimal drainage. Absorbs odor with cyclodextrin technology. Not inactivated by wound protein; Manages drainage; Longer wear time; Low residue formula. Protective, occlusive barrier; satin finish backing.

Say goodbye to smelly hydrocolloids.

As useful as they are, traditional hydrocolloid dressings have one major drawback: their distinctive odor upon removal. Now theres an alternative. Medlines Exuderm OdorShield dressing, a patented new hydropolymer, absorbs odors as it absorbs wound exudate, making dressing changes more pleasant for caregivers and patients alike.

The benefits of an advanced hydrocolloid, plus odor control.

The new Exuderm OdorShield dressing absorbs exudate from lightly to moderately draining wounds and provides a protective, occlusive barrier that facilitates autolytic debridement, granulation, and epithelialization. Its smooth satin backing, tapered edge, and low-residue formula help ensure longer wear. But unlike any hydrocolloid on the market, Exuderm OdorShield controls odors, too.

Exuderm OdorShield makes charcoal-based dressings obsolete.

Its a fact that charcoal dressings dont work well on exudative wounds (their odor-absorbing properties are deactivated by the proteins in wound fluid). Exuderm OdorShield is designed to absorb odors in the presence of wound exudate; plus, its more conformable, absorbs more fluid, and requires no secondary dressing.

How Exuderm OdorShield dressings control odors:

What are cyclodextrins?

Exuderm OdorShield gets its odor-absorbing properties from cyclodextrins, which are naturally occurring, noncytotoxic molecules (bucket-shaped oligosaccharides derived from starch).Their unique molecular structure helps them capture odor-causing molecules (see Figure 1).The use of cyclodextrins is well established in the pharmaceutical industry to disguise unpleasant tastes and odors in medications. Cyclodextrins have also been used in consumer applications, for example, Febreze products, to control odor.

How do cyclodextrins capture odor molecules?

The lipophilic ("oil-loving") interior of the bucket-shaped molecule attracts and traps other lipophilic substances, such as most odor-causing molecules. The exterior of the cyclodextrin molecule is hydrophilic (
water-loving"). At least a small amount of water is necessary for the cyclodextrin molecule to interact with odor molecules. This water is supplied by the hydrocolloid as it absorbs wound exudate or body fluid.

Testing the odor-absorbing capability of Exuderm OdorShield:

Electronic nose (E-nose) technology

This existing technology was further developed to test the odor-absorbing properties of the new Exuderm OdorShield dressing.The dressing material was placed in a special container (see Figure 2) along with a solution of simulated wound fluid and test odor (butyric acid, valeric acid, cadaverine, or putrescine).

Figure 2. E-nose testing container

Table 1. Odor absorption measurements from E-nose tests. Higher numbers indicate better odor absorption.

Table 2. Odor absorption measurements from E-nose tests. Higher numbers indicate better odor absorption.

The human nose confirms that Exuderm OdorShield is better at controlling odor.

To further test the odor-absorbing properties of Exuderm OdorShield, a blind psychosensory test versus DuoDerm was performed. Panelists were asked to rate the level of odor remaining in a vial, which contained a sample dressing plus a test odor, after 24 hours. Once again, Exuderm OdorShield was more effective at absorbing odor (see Figure 3).

Figure 3. Results of psychosensory test. Lower numbers indicate better odor absorption.

Cyclodextrins vs. Charcoal

The odor-absorbing capacity of charcoal dressings is deactivated by serum proteins. In contrast, cyclodextrins odor-absorbing function is enhanced by the combination of water and serum proteins. In the presence of water alone, the cyclodextrin molecule achieves a somewhat flexible bucket shape. In the presence of serum proteins and the consequent binding of the hydrophilic serum proteins to the outside wall of the cyclodextrin structure, the shape of the cyclodextrin molecule is further strengthened in the preferred bucket conformation. Thus, the odor-absorbing interior of the bucket is rendered more stable and active in the presence of serum proteins.

In essence, charcoals odor absorption properties are destroyed by wound fluid, while cyclodextrins odor-absorbing potential is actually enhanced by wound fluids. This is borne out by actual odor absorption measurements; see the table below, which compares Exuderm OdorShield to charcoalbased dressings in the presence of increasing quantities of serum proteins.

Fluid absorption: just as important as odor control.

With all the talk about odor control, it might seem weve forgotten about the primary purpose of a hydrocolloid dressing: to protect and absorb fluid from a wound. Rest assured, Exuderm OdorShield does its job of absorbing exudate as well or better than many other hydrocolloids on the market. In laboratory tests with saline solution, it absorbed much more fluid than a charcoal dressing and about the same amount as a competitive hydrocolloid of about double the thickness (see Figure 4). Thinner dressings of comparable absorbency such as Exuderm OdorShield are less obtrusive and less prone to accidental detachment compared to thicker competitive products.With Exuderm OdorShield, you really do get the best of everything: high fluid absorption with a super low profile, as well as odor control.

Exuderm OdorShield: a dressing like no other.


  • Hydropolymer substrate absorbs exudate from lightly to moderately draining wounds.
  • Added cyclodextrins absorb odors, making dressing changes more pleasant and helping restore patient dignity.
  • Low-residue formula allows longer wear time and easier dressing changes.
  • Tapered edge design and smooth, low-friction backing prevent rollup and extend wear time.
  • Translucent appearance allows visualization of wound without removing dressing.
  • No secondary dressing required


  • Wounds with light to moderate drainage
  • Pressure ulcers (stage IIIV)
  • Partial and full-thickness wounds
  • Leg ulcers
  • Donor sites
  • Lacerations and abrasions
  • First- and second-degree burns


  • Third-degree burns

Change frequency:

  • May be left in place up to 7 days, depending on wound exudate.
