Hydrosorb a Gel With Polyurethane Film Covering, Moist Wound Dressing
Examples Aquasorb, Biolex Wound Gel, Carrasyn Gel (2)
2 The Main Features of Hydrogel
Prevent fluid loss
Provide extra moisture, gel is between 60-90 water
Prevent micro-organism and water entry
Absorb contaminating bacteria and debris
3 The Main Features of Hydrogel
Maintain an optimal healing temperature
Transparency to view wound
Reduce friction and pressure, which inhibit healing
4 The Main Features of Hydrogel
Improve patient comfort
Easy to apply
Easy and painless to remove
Allow water vapour to pass out
Help cleanse wound
Breakdown necrotic tissue
Promotes granulation and re-epithelisation
Continuous long term absorption
5 Hydrogels on the Market
A number of companies manufacture hydrogel products for wound care.
There are slight differences between each hydrogel.
But there is a common theme amongst the design of all hydrogel products
6 All Hydrogels
Provide a moist wound environment to enhance healing.
Debride necrotic tissue to allow the regeneration process to begin.
Absorb excess exudate from the wound to prevent slough formation.
Hydrogels are available in sterile and non-sterile sheets and amorphous gels.

Useful in partial- and full- thickness wounds
Deep wounds with tunnelling or sinus tracts
Light to moderately exudative wounds
Chronic and reoccurring wound, with prolonged formation of granulation tissue
Burns first and second degree, hydrogel has cooling and pain relieving properties
Skin grafts, promotion of re-epithelialisation at donor sites
Can conform to body contours, therefore can be used in conjunction with an elastic compression bandages to prevent the development of oedema at the wound edges
Reduction in scar sizes
Cushioning effect for pressure reduction.
Can be impregnated with topical. medications.
Radiation tissue damage.
Not useful for highly exuding wounds
Should not be used on exposed structures such as bones, muscles or tendons in clinically infected wounds or ulcera resulting in chronic infections, following tuberculosis, syphilis, deep mycotic infections
16 Methods of Use
Clean and dry wound.
Apply Hydrogel, sheet, gel or impregnated dressing.
17 Methods of Use
3. Cover wound with an adherent dressing to secure it. Sloughy wounds may need an absorbent dressing for maximal absorption.
4. All gels can be irrigated from the wound with saline solution without causing tissue damage or pain to the patient. (5).
18 Frequency of Dressing Change
Hydrogel dressings such as Hydrosorb and Hydrosorb plus are permanently moist, transparent dressings.
The transparent nature allow for easy inspection of the wound at any time without removal.
19 Frequency of Dressing Change
Hydrosorb and Hydrosorb plus save the wound from fluid loss and posses a sucking activity that provides sustains long term absorption of fluid.
20 Frequency of Dressing Change
Daily redressing not required to monitor wound.
The dressing can remain undisturbed for up to 7 days.
However some particularly nasty wounds would require redressing every 4-5 days.
21 Advice to Patient
Points to discuss with patients and caregivers
Wound healing can be a long process.
Need clinician, patient, caregiver communication.
Common goals and outcomes some patients could begin to feel discouraged.
22 Advice to Patient
Patients need to be aware of factors that delay wound healing
Other chronic medical conditions (e.g. Heart disease).
Poor blood supply.
23 Advice to Patient
Alert clinician if any adverse reactions or irritations occur.
Patients need to know how to store Hydrogels appropriately.

25 Case Study
Mr. Plod. Aged 75.
Medical history Peripheral arterial disease, Long standing type II diabetes, with some associated complications, renal disease and micro-vascular changes.
Lives alone, home care once a week.
Receives the pension.
Acquired a deep puncture injury last week while gardening.
Producing mild exudate. But no signs of infection.
26 Why Use a Hydrogel Dressing?
Mild exudating wound, hydrogels absorb slowly and continuously.
Arterial disease means there will be a decreased blood supply. The hypoxic environment under the occlusive wound dressing enhances angiogenesis. Therefore increasing blood flow, which brings products for healing.
27 Why Use a hydrogel Dressing?
Hydrogel is soft and elastic. Provides cushioning and protection that can assist wound healing.
Mr. Plod can continue working in his veggie garden with minimal risk to his injury.
Can leave dressing on for the week between homecare visits.
More economically viable, decreased wound dressing decreases cost to Mr Plod who receives the pension.
28 Why Use a hydrogel Dressing?
Hydrogels help maintain a moist wound environment.
This assists epithelial migration, therefore decreasing healing time.
But doesn't trap exudate that may decrease granulation tissue and cause local ischemia.
Hydrogels also provide optimum temperatures for wound healing.
29 Remember to Manage..
Mr. Plods nutritional status. Make sure he is having his Weet-Bix for breakfast!!
Management of diabetes, bacteria love glucose. Need tight glucose control.
Monitoring of PVD to insure adequate blood supply to wound.
Wound care needs a multidisciplinary approach. Even a super dressing alone is not enough!!!
