Flivasorb & Flivasorb AdhesiveChronic wounds present many challenges to the nurse and patient. In wounds that are producing large amounts of fluid, devising strategies to minimise the impact on the patient’s physical and psychosocial wellbeing can be particularly demanding. Flivasorb® and Flivasorb® Adhesive are superabsorbent dressings particularly suited to wounds that are exuding heavily. This ‘how to’ guide focuses on how Flivasorb and Flivasorb Adhesive work and are beneficial in such patients.

What is exudate?
Exudate is derived from the fluid that has leaked from capillaries into body tissues around the wound. In acute wounds, exudate stimulates and supports healing by:

  • aiding the migration of cells and immune and growth factors across the wound bed
  • supplying essential nutrients for the cells
  • assisting dead or damaged tissue to separate from good tissue (autolysis) (WUWHS, 2007).

However, in chronic wounds, the composition of exudate is different with higher levels of matrix metalloproteinases (MMPs), which break down healthy tissue as well as prolong the inflammatory response. This may have harmful effects that prevent healing and even cause further damage. High exudate production can have a number of causes, eg sustained inflammation, local infection, venous insufficiency, lymphatic disease (eg lymphoedema), congestive cardiac failure, renal or hepatic failure, medication, malnutrition, heat, or reduced willingness or ability to cooperate with treatment (eg compression therapy) (Gardner, 2012). The volume of exudate is also linked to the size of the wound.

Dressings and exudate management
The main roles of dressings in exudate management are to absorb excess exudate while keeping the wound bed sufficiently moist to enhance healing. However, the wound should not be kept so wet that the surrounding normal skin becomes soggy (macerated) and prone to damage.

Consequences of poor exudate management

  • delayed healing
  • discomfort or pain
  • leakage, soiling and odour - these are a particular cause of distress and concern  for affected patients (Jones et al, 2008)
  • changes in the normal skin around the wound such as maceration and excoriation where the skin becomes softened and starts to break down - these can contribute to wound pain and may cause the wound to enlarge (Benbow and Stevens, 2010)
  • high frequency of dressing change causing increased inconvenience to the patient and increased use of healthcare resources and nursing time (Davis, 2012; Menon, 2012; WUWHS, 2007)
  • protein loss and fluid/electrolyte imbalance
  • reduced concordance with treatment such as compression bandaging or leg elevation.

What is Flivasorb?
Flivasorb is a superabsorbent dressing that is indicated for the management of moderately to heavily exuding wounds, including pressure ulcers, leg ulcers, diabetic ulcers, postoperative wounds healing by secondary intention, laparotomy wounds, fistulae/sinuses and superficial or partial thickness burns.
Flivasorb has a polyethylene wound contact layer which minimises wound adherence. The core is made of cellulose and superabsorbent polymer (sodium polyacrylate) particles. The outer layer is breathable and prevents leakage (Tadej, 2009).

What is Flivasorb Adhesive?
Flivasorb Adhesive is the same as Flivasorb, but has an adhesive border (Figure 1). This means that the dressing requires no additional fixation, and is particularly useful for areas of the body where it may be difficult to apply a dressing that requires secondary fixation, eg the sacrum or groin.
How do they work?
Flivasorb and Flivasorb Adhesive absorb exudate through the wound contact layer into the core of the dressing. The dressing is able to absorb upto 20 times its own weight in fluid. When liquid enters the core, it attaches to the superabsorbent polymers and forms a gel, which causes the dressing to swell. The formation of a gel means that, unlike with some foam dressings, fluid is not released if the dressing is compressed. The gelling action also traps unwanted components of the exudate such as bacteria, proteases and inflammatory mediators within the dressing (Wiegand et al, 2009).

Choosing a dressing to manage exudate
A wide variety of wound dressings is available and choice of a dressing will take into account a number of factors, including the level of exudate production, which can change during the healing process. The aim of exudate management is to maintain a moist wound bed to aid healing, while keeping exudate away from the skin. If a dressing of too high absorbency is selected, the wound bed may be dried out; if the dressing is not sufficiently absorbent, the skin surrounding the wound may become macerated and leakage may occur, causing pain and distress for the patient (Gardner, 2012).

Foams vs superabsorbents
For wounds that are highly exuding, high absorbency is required to make dressing change frequency manageable and to avoid periwound skin problems. Traditionally, foam dressings have been used to manage high exudation. However, in some cases the fluid handling capacity may be less than optimal, necessitating more frequent dressing changes, and an inability to retain fluid under pressure, eg under compression bandaging.

The choice of wound dressing should be made in the context of the aetiology of the wound, the status of the wound, and the other needs of the patient.

Advantages of using Flivasorb and Flivasorb Adhesive
Flivasorb and Flivasorb Adhesive have properties that mean they fit well with the profile of an ideal dressing for the management of high exudation (Adderley, 2008; Stephen-Haynes, 2011).

  • They are able to absorb and retain high volumes of exudate. This means that they have the potential for extended wear time and reduced dressing change frequency. Importantly, the high absorption and retention reduces the likelihood of periwound skin damage.
  • The dressings are comfortable and easy to apply, and due to its adhesive border Flivasorb Adhesive does not require secondary fixation.
  • Both dressings may be used as the primary dressing, or as a secondary dressing with an appropriate antibacterial dressing on infected wounds or over a cavity dressing for deeper wounds.
  • The outer layer of the dressings prevents strikethrough and the dressings are constructed to stay intact even when saturated. The non-adhesive wound contact layer minimises trauma and pain on removal of the dressings.
  • Both retain the fluid they have absorbed when under pressure, such as under compression bandaging. This reduces the risk of maceration or excoriation with, for example, sacral pressure ulcers or venous leg ulcers. This makes Flivasorb ideal for use in the management of venous leg ulcers where compression bandaging is being used and Flivasorb Adhesive ideal for use in the management of sacral pressure ulcers due to the excellent fixation it provides in such awkward areas.


Page Points

  • High levels of exudation may be challenging to manage and contribute to delayed healing and have high human and economic costs.
  • Flivasorb and Flivasorb Adhesive are superabsorbent dressings that can absorb and retain high volumes of exudate, even under pressure.
  • The high absorbency of Flivasorb and Flivasorb adhesive has the potential to reduce the risk of periwound maceration, wound discomfort and dressing leakage, and therefore may reduce dressing change frequency, enhance patient comfort and result in considerable savings in overall dressing and nursing costs.
