Oxidised cellulose is used adjunctively for surgery and minimally invasive procedures to support haemostasis in capillary, venous, and smaller, more diffuse, arterial bleeding, where conventional hemostasis measures like sutures or ligatures are neither effective nor practical.

What is oxidised cellulose?

Oxidised cellulose is a water-insoluble derivative of cellulose. The cellulose can be sourced from any natural source, such as wood or flax but is most commonly from cotton.

It can also be sourced from pre-processed cellulose products, such as viscose or lyocell, in which case, a regenerated product is made, known as oxidised regenerated cellulose.

Oxidised cellulose is an absorbable haemostat. It is antimicrobial and acts as an adhesive barrier.

Our oxidised cellulose is derived from 100% natural finest cotton. It contains no chemical additives or accelerants and is broken down and absorbed by the body.

It is made using a controlled oxidation process that gives the product the characteristics required to provide an absorbable haemostatic dressing.

How does oxidised cellulose work?

Oxidised cellulose dressings work to stop bleeding by mechanically triggering platelet aggregation and helping the blood clotting process to begin. The fibres can absorb up to seven times their volume in blood. When saturated, the oxidised cellulose swells into a gelatinous mass. Oxidised cellulose is naturally acidic, and it is this acid that starts to break down the blood cells, triggering the clotting process in the body. The oxidised cellulose also lowers the pH within the wound due to its acidity. This creates a hostile environment for most bacteria and provides antimicrobial benefits.

Indications For Use

RESORBA® CELL is used adjunctively during surgical and minimally invasive procedures to control haemostasis of capillary, venous and minor arteriolar bleeding when conventional haemostatic methods such as ligation are not effective or practical. RESORBA® CELL can be cut to size for use (not only) in endoscopic procedures.
