In the wound care community, compression therapy is standard of care for edema control and wound healing for several conditions, including venous insufficiency ulcers, mixed arteriovenous insufficiency ulcers, and other lower extremity wounds complicated by edema. Compression therapy is used to reduce inflammation, aid in fluid collection, help decrease pericapillary cuffing, and remove toxins such as lactic acid. Satisfactory compression includes consistent application, patient compliance, and exudate management with the goal to allow continuous, sustained, therapeutic pressure compression that is comfortable for the patient and that subsequently leads to better compliance.1
The most common bandage systems are single, long-stretch bandages; paste bandages; and multilayer compression systems. Single, long-stretch bandages require a daily reapplication; as such, they may be most beneficial in wounds that require daily dressing changes along with edema management.2
Paste bandages customarily are impregnated with zinc oxide or calamine. Paste boots often are uncomfortable and provide sustained compression only while the patient is ambulating. In our experience, these bandages may lose sustained compression after 24 hours’ use.
Most wound centers use multilayer systems as the gold standard. These compression systems come in prepackaged kits and have been found to be more effective than traditional paste boots or single, long-stretch bandages. Multilayer wraps comprise either a 3-layer or 4-layer system. Three (3)-layer systems consist of a padded layer, compression layer, and an outer layer to keep the system intact; 4-layer systems feature an additional layer for exudate management. These graduated compression systems are claimed to provide 30 mm Hg to 40 mm Hg of pressure, maintain constant compression for approximately 1 week, and are not dependent on ambulation.3
UrgoK2. UrgoK2 (URGO Medical) is an easy-to-apply, 2-layer compression bandage that features the Dual Compression System, designed to optimize the safe application of the recommended therapeutic pressure and increase patient compliance. This system provides the same high standard compression provided by 4-layer bandage systems. Numerous clinical studies, including a large randomized controlled trial (RCT), have proven the ability of the wrap system to provide the 3 Cs of a good compression wrap — Consistency, Continuity, and Comfort.4-8
The first layer of the UrgoK2 system (KTECH) includes wadding of viscose and polyester and a knitted layer of polyamide and elastane. This white, short-stretch bandage provides compression, protection, and absorbency. Layer 2 (KPRESS) is comprised of acrylic, polyamide, and elastane; this pink/beige cohesive long-stretch bandage layer provides the additional compression necessary to achieve the therapeutic pressure for leg ulcers and secures the bandage system in place. Both layers in the UrgoK2 system contain ovals that turn into circles when the appropriate tension is applied to the material. The latex-free system comes in 2 sizes depending on the circumference measured 2 cm above the patient’s malleous. Figure 1 shows proper application.
