For a wound to heal, it needs to exude. Indeed, moist wounds heal 2-3 times faster than dry wounds1. Sometimes, however, heavily exuding wounds can do more harm than good.
Too much moisture can hamper healing
Superabsorber dressings are used to extract much of this moisture - and its harmful bacteria. This creates an environment where skin integrity is maintained and wounds can heal effectively.
Control excess exudate
ConvaMax™ is a new Superabsorber dressing designed to manage the challenges around highly exuding wounds. It combines high performance with softness and conformability. Highly absorbent, even under compression, it locks excess exudate and bacteria away from the wound.
What causes exudate production
Exudate is a liquid containing proteins and white blood cells. It is the body's defence mechanism as a result of inflammation, and it slowly seeps from blood vessels within the wound.
Effects of exudate on wound healing:
Exudate assists healing by1,2,4:
Excess exudate may2:
Non-healing wounds have higher levels of pro-inflammatory proteins which accelerate the inflammatory process. This encourages the production of enzymes and degrading proteins, which in turn can slow down or halt wound healing by hindering cellular proliferation and migration. Non-healing wounds have lower levels of growth factors which are essential for new cell development2,5
The challenges of poor exudate management for skin integrity
"Due to the nature and components of the exudate, it may be acidic in nature so causing burning and trauma" 1
In the UK between 2012 and 2013, for example, it is estimated that 2.2 million patients were treated for acute or chronic wounds by the NHS. This results in a total cost of between £4.5 - 5.3 billion3.
Superabsorber dressings can be an appropriate solution to effectively contain excessive exudate and manage symptoms including:1

Drier wounds are also at risk
It's worth noting that it's not only high levels of exudate that can slow down healing times. Low levels of exudate, such as ischaemic and arterial wounds and neuropathic diabetic foot ulcers, can have a similar effect.1
