How does the 3M™ Coban™ 2 Compression System avoid slippage? Ideally, a compression bandage system should stay in place for the duration of wear because slippage will result in a failure to deliver compression. However, bandages may slip down the limb becoming bunched and uncomfortable, thereby losing some compressive ability5,20


.


When the inner foam layer of 3M™ Coban™ 2 and 3M™ Coban™ 2 Lite is compressed, the system holds on to the skin, and prevents slippage. After application, the inner layer provides a cohesive surface for the attachment of the outer compression layer. The two layers lock together to create an inelastic sleeve that conforms to the limb and reduces the potential for slippage and bunching.


A laboratory study of 10 different compression systems assessed slippage over 48 hours of wear in 60 healthy volunteers27


. 3M™


Coban™ 2 and 3M™ Coban™ 2 Lite were shown to have the lowest slippage and were the most effective in maintaining resting pressures and amplitudes at values known to be effective for ulcer healing27


(Figure 2).


A clinical study in patients with venous leg ulcers found that slippage measured at each bandage change was significantly lower for 3M™ Coban™ 2 when compared with a four-layer bandage system5

Apply the inner foam layer with the foot dorsiflexed and starting at the base of the fifth metatarsal head. Leaving the bottom of the heel exposed, proceed by winding the foam up the leg using minimal overlap to just below the fibular head. Cut off excess material.


Apply the compression layer with the foot dorsiflexed and starting at the base of the fifth metatarsal head. Apply at full stretch and proceed up the leg using 50% overlap. The bottom of the heel should be covered with the compression layer.

End at the fibular head or just below the back of the knee and level with the top edge of the foam layer. Cut off any excess material.


Gently press and conform the entire surface of the system to ensure that the two layers are firmly bound together.

Indications for 3M™ Coban™ 2 3M™ Coban™ 2 is suitable for most patients with venous leg ulcers, lymphoedema and other conditions where compression therapy is appropriate, and for patients with different limb sizes and shapes6


(Box 3). It is important to ensure adequate arterial blood flow before applying 3M™ Coban™ 2 (Box 4).


Indications for 3M™ Coban™ 2 Lite 3M™ Coban™ 2 Lite achieves a lower resting pressure than 3M™ Coban™ 2. As a result, it is more comfortable for patients less tolerant of compression therapy (Box 3), including


those who: n


n have a leg ulcer of mixed aetiology with an ABPI ≥ 0.5


are new to compression and have unknown tolerance for compression


n are frail or less mobile6 .


3M™ Coban™ 2 Lite reduces the risk of tissue damage and necrosis when compression therapy is considered necessary in patients with an ABPI between 0.5 and 0.86


careful observation for early signs of skin damage remains a requirement for the safe management of these patients.


Clinical practice points Prior to application Wounds should be managed with dressings appropriate to the wound condition. The decision to use 3M™ Coban™ 2 or 3M™ Coban™ 2 Lite will be guided by full clinical assessment, including assessment of peripheral arterial circulation (ABPI) (see Box 4) and the patient’s ability to tolerate compression.
