Oxidized cellulose

What is oxidized cellulose?

Oxidized cellulose (OC) is generated by the oxidation of natural material. Bioster uses long-fibred type cotton of the highest quality. Particular fibres of this cotton are 35 – 50 mm long, diam. 12-25 micrometre, they are twisted, flattened tubes sealed at one end. The basic unicellular fibre is built form microfibrils, the size of which is determined from units to tens nanometres. Thus it is possible to consider OC as a material with natural nanostructure. Using textile machines, these thin fibres are physically connected by the twisting of basic tubes to long fibres yarn. This process is called spinning.

What is the difference between oxidized cellulose and oxidized regenerated cellulose used by our competitors?

Oxidized regenerated cellulose (ORC) originates by the oxidation of chemically regenerated cellulose. Cellulose raw material is chemically transformed to a soluble form and long, smooth and glossy fibres of the uniform diameter are formed. Further processing of this yarn and oxidation process is the same as with OC. An advantage of ORC is a higher mechanical strength in a dry form. The advantage of OC used by Bioster is a larger specific surface which is advantageous for creating an adhesive layer with thrombocytes and, compared with OCR, results in higher haemostatic capacity. ORC may contain chemical residues from the regeneration process. OC and OCR are two separate items of American pharmacopeia USP and it is possible to distinguish them microscopically.

Wound treatment

What is Traumastem Biodress and what are its main strengths?

Traumastem biodress is a unique natural oxidized cellulose dressing for the treatment of acute and chronic wounds. It considerably accelerates healing, particularly in the granulation and epithelization phases. In coated, highly exuding wounds, Traumastem biodress cleans and revitalizes the wound base and triggers granulation. If applied to clean granulated wounds, epithelization begins very quickly both at the edges and the centre of wounds. Traumastem biodress is applicable to all types of wounds (however, it is not intended for dry and necrotic wounds). Traumastem biodress considerably reduces pain in a wound, thus improving the mental and overall condition of a patient. Traumastem biodress is fully absorbable, atraumatic, hypoallergenic and without any side effects.

How is Traumastem Biodress used?

Before the application of Traumastem biodress, we recommend applying a compress solution to the wound for 10 – 15 minutes. Once the area around the wound has been treated by standard means (e.g. indifferent paste or antimicrobial solution, as the case may be), apply Traumastem biodress to the wound, ensuring that it does not extend over the edge of the wound. The size of the applied Traumastem biodress may be adjusted to the size of the wound by trimming. Then apply a secondary dressing (such as oily gauze) and fix it in place with a hydrophilic bandage. The dressing may be kept on the wound for 1–3 days. The frequency of redressing depends on the quantity of exudate.

How quickly does Traumastem Biodress relieve the pain and reduce the wound area?

In our experience, relief from wound pain already arrives during the first week of application.

In which size is Traumastem Biodress produced and is it covered by health insurance?

Traumastem biodress is produced in dimensions of 10×10 cm and 7.5×5 cm. Both versions are fully covered by health insurance.

Does Traumastem Biodress have any side effects or cause allergy? What are its contraindications?

To date no allergic reactions after the application of Traumastem biodress have been found. Traumastem biodress is completely biocompatible. It is not suitable for dry and necrotic wounds.
