Alginate Wound Dressing
Sequa®Sorb Alginate Wound Dressing is an advanced wound dressing manufactured from sodium alginate extracted from natural seaweeds. With the calcium in the dressing being exchanged with sodium from wound fluid, the dressing will turn into gel when in contact with wound exudates, which maintains a moist wound healing environment and is ideal for the management of exuding wounds.
FEATURES
- High Absorbency
Alginate dressing can absorb large amounts of wound exudates then forms a gel to protect the wounds and encourage wound healing. - Wet Strength
Alginate wound dressing can be easily remove in one piece. - Gel-forming Property
After absorption of exudates, the exchange of calcium in the dressing and sodium from wound fluid forms a stable gel that can maintain a moist wound healing environment promoting cell re-generations. - Pain Reducing
Owing to the protection of gel, peripheral nerves within the wound bed are less likely to be stimulated by external process so there is a potential for pain reduction [ Ref 2 ] - Haemostatic Function
The release of calcium ions can cause the aggregation and deformation of erythrocyte and increase the platelet activating to promote clotting. In addition, its special physical characteristics play an important role in the process of haemostatic [ Ref 3 ]
Natural Dressing for Moderate to Heavily Exudate
- Alginate dressing, derived from seaweed, is highly absorbent and biodegradable can be applied to aid autolytic debridement. Strong hydrophilic gel formed to achieve its high absorption property when the dressing contacting with wounds exudate, and this help to control wound secretion levels and minimize bacterial contamination. It is not necessary to remove the alginate fiber trapped in wound because of its biodegradability. Additionally, alginate dressing assist in haemostasis [ Ref 1 ] and allows intact removal.
How does Alginate Dressing work?
- When the alginate is in contact with wound exudates, calcium ions in the dressing is exchanged with sodium ions from wound fluid turning the calcium alginate into sodium alginate. Sodium alginate becomes gel when in contact with wound exudates which help to maintains a moist wound environment that supports the wound healing process. The gelling nature of the alginate also helps the removal of the dressing without damaging the newly formed tissue.
Indications
It has been proven clinically [ Ref 4,5 ] that alginate is indicated for the management of moderately to heavily exuding chronic wounds and acute wounds, and to control minor bleeding in superficial wounds Pressure ulcers.
Leg ulcers
Venous and arterial ulcers
Diabetic ulcers
Lacerations
Abrasions
Graft wounds and donor sites
Contraindications
- Alginate dressing is not indicated for use on the following:
Surgical implantation
Dry wounds
To control heavy bleeding
Individuals who are sensitive to or who have had an allergic reaction to the dressing
Use under gauze
