Cutimed® Sorbact®Bacteria-Binding Dressing
Cutimed Sorbact by BSN-Jobst is an innovative advanced wound dressing for infected wounds that uses the basic physical principle of hydrophobic interaction. Hydrophobic (water repellent) particles accumulate in an aqueous environment and are held together by the forces of surrounding water molecules. Wound bacteria are irreversibly bound to the dressing when they come into contact with Cutimed Sorbact's hydrophobic dressing fibers in the moist wound environment.
Since no chemical agents, such as local antibiotics or antiseptic products are used, there is little risk.
Effective Against MRSA and VRE
Fighting multi-resistant bacteria has become increasingly important in wound treatment and hospital management. The Sorbact method is even effective against MRSA (methicillin-resistant Staph. aureus) and VRE (vancomycin-resistant Enterococcus) as their resistance against antibiotics does not change their hydrophobic properties nor their abiity to bind to Cutimed Sorbact.
Advantages over other antimicrobial approaches:
--No Risk of Allergies: highly skin compatible
--No Contraindications: products can be used during pregnancy and breastfeeding and on children
--No Cytotoxicity: no chemically active substances are released into the wound that might impair the healing process
--No Promotion of Bacterial Endotoxin Release: bacteria are not destroyed, preventing endotoxin release, and supporting natural wound healing
--No Development of Bacterial or Fungal Resistance: since no antiseptics or antibiotics are used, there is no resistance development
Works Well With Other Dressing:
Depending on the degree of exudate, Cutimed® Sorbact® may be used with amorphous hydrogels as well as secondary dressings, including:
- gauze or other dressings for additional absorption
- hydroactive foam dressings
Indications for Use:
Cutimed Sorbact can be used for all types of contaminated, colonised or infected exuding wounds, regardless of their etiology, such as:
- chronic wounds, e.g. venous, arterial, or diabetic ulcers and pressure ulcers
- wounds after excision of fistulas and abscesses
- postoperative dehisced wounds
- traumatic wounds
Instructions for Use:
1. Clean the wound as usual. If desired, gently press a Cutimed® Sorbact® round swab against the moist wound surface to remove superficial microbial contamination.
2. Direct wound contact is a prerequisite for the effective binding of microorganisms. Always apply the dressings in a way that ensures direct contact with the wound surface.
3. In deep or cavity wounds, apply Cutimed® Sorbact® swabs or ribbon gauzes and leave a part of the dressing sticking out of the wound so it can easily be removed. if required, cover with an absorbent Cutimed® Sorbact® dressing pad. In superficial wounds, apply a Cutimed® Sorbact® dressing pad. In superficial wounds, apply a Cutimed® Sorbact® swab or dressing pad. Apply the dressing pad to the wound green side down.
4. Depending on the amount of wound exudate, Cutimed® Sorbact® swabs, ribbon gauzes, and round swabs can be combined with all types of hydroactive secondary dressings such as foams or alginates.
Do not combine Cutimed Sorbact with ointments or creams.
5. If required, use a bandage or tape for fixation.
6. When the wound is clean and shows signs of healing, it is recommended to switch to other types of modern dressings (e.g. for moist wound management).
What is the Sorbact method?
A unique mode of action to bind and inactivate wound bacteria and fungi by hydrophobic interaction without using any antiseptic or antibiotic agents. It is based on the binding of hydrophobic structures on bacterial cell surfaces to the strongly hydrophobic coating of Cutimed Sorbact fabric.
What is hydrophobic interaction?
Hydrophobic interaction is a basic physical principle: When two hydrophobic (= water repellent) particles become in contact in an aqueous environment, they will bind to each other with help from the surrounding water molecules which hold them together.
Why do microorganisms have hydrophobic structures, and what is their natural purpose?
Cell surface hydrophobicity is one of the microorganism's natural prerequisites to take in food, to bind to surfaces or to each other e.g. for exchange of genetic information. The adherence of bacteria to tissue cells by hydrophobic interaction is the first step of infection.
What is the benefit of the Sorbact method?
Cutimed Sorbact does not release any chemically active substances into the wound as e.g. silver dressings or other common antiseptics do. Therefore potential risks like bacterial resistance or cytotoxicity can be ruled out completely.
Common bactericidal antiseptics destroy bacterial cells which can promote bacterial endotoxin release. By simply binding the microorganisms Cutimed Sorbact eliminates this risk.
All Cutimed Sorbact dressings can be used without hesitation during pregnancy or breastfeeding as well as in infants.
What gives Cutimed Sorbact its strongly hydrophobic properties?
The fabric of Cutimed Sorbact is coated with the derivative of a natural fatty acid (DACC, dialcyl carbamoyl chloride). Its long alkyl groups make for strong hydrophobicity and therefore bacteria binding properties of Cutimed Sorbact dressings.
Does Cutimed Sorbact release any substances into the wound?
The special bacteria binding coating is firmly bound to the fabric fibres and will not be released into the wound. Cutimed Sorbact does not use any active substances to achieve microbial balance in the wound but works by a purely physical method.
What kind of fabric is Cutimed Sorbact made of?
Acetate fabric except for the ribbon gauze which is made of cotton for higher conformability and easier application in deep wounds. The dressing pad contains a soft absorbent core made from polyester and viscose.
Why is acetate fabric used?
It is a smooth fine meshed material which reduces the risk of tissue ingrowth and of sticking to the wound.
Can Cutimed Sorbact be re-sterilised by steam?
No, re-sterilisation is not recommended.
What is the shelf life of Cutimed Sorbact?
Shelf life is 5 years for the absorbent pads, swabs and ribbon gauzes and 3 years for the Cutimed Sorbact gel dressings.
What are the indications for Cutimed Sorbact?
Unclean, colonised or infected wounds regardless of aetiology, e.g. chronic wounds (diabetic foot ulcers, leg ulcers, pressure sores), post-operative dehisced wounds, traumatic wounds, or wounds after excision of fistulae or abscesses.
Cutimed Sorbact is also effective in dermal fungal infections.
In dry or low exuding wounds, Cutimed Sorbact gel is recommended to provide the necessary moisture needed for the bacteria binding effect and to avoid any potential of sticking to the wound.
Are there any contraindications?
There are no known contraindications for Cutimed Sorbact absorbent pads, swabs or ribbon gauzes.
Cutimed Sorbact gel should not be used in case of known sensitivity to propylene glycol. In these cases it is recommended to use Cutimed Sorbact swabs in combination with Cutimed Gel which does not contain propylene glycol.
All products can be used without hesitation during pregnancy and breastfeeding as well as on children.
When should Cutimed Sorbact be used?
Cutimed Sorbact and Cutimed Sorbact gel can be used in any wound where the primary goal is to remove micro-organisms (bacteria or fungi) in order to activate or support the natural wound healing process. This also includes preventive antiseptic treatment of wounds at risk of infection (e.g. in traumatic wounds).
Why is it important to decrease the number of bacteria in a non-healing wound?
The healing process slows down or stops in critically colonised or infected wounds. By reducing the microbial load Cutimed Sorbact also reduces odour, exudate level, wound pain, and the risk of transmission of bacteria in the environment.
Which are common wound bacteria that can be found in infected wounds?
Common examples are Staphylococcus aureus, Enterococcus, Escherichia coli, Pseudomonas aeruginosa, haemolytic Streptococci, Klebsiella, Citrobacter, Morganella.
Which kind of microorganisms bind to Cutimed Sorbact?
Cutimed Sorbact is effective against all common wound pathogens: gram positive (e.g. Staphylococcus, Streptococcus, Clostridium) and gram negative bacteria (e.g. Pseudomonas, E. coli, Enterobacter) as well as fungi (e.g. Candida albicans) [Ljungh, Wadström; Microbiol. Immunol. 39 (10), 1995, 753-57].
This includes antibiotic resistant bacteria like MRSA or VRE as their resistance does not change their binding to Cutimed Sorbact.
Can microorganisms overcome the binding to Cutimed Sorbact?
No, the binding is irreversible in a moist wound environment.
Can the microorganisms continue to grow when bound to Cutimed Sorbact?
No, bound microorganisms are inactivated and do not replicate. When bound to a surface it is the microorganisms' natural behaviour to slow down their metabolism. Consequently, the formation and emission of bacterial toxins are also slowed down or stopped.
Does the microbial binding of Cutimed Sorbact reach a saturation point?
A saturation point was not reached in an in-vitro investigation by Ljungh et al. [JWC 15 (4), 2006, 175-80]. A binding capacity of up to one hundred million bacteria per square cm dressing was determined. This number exceeds the bacterial load that you would find in an infected wound.
What about microorganisms located in the pus or debris of the wound?
Debris and pus also have hydrophobic properties and bind to Cutimed Sorbact as well as the microorganisms.
How long does it take the microorganisms to bind to the dressings?
An in-vitro test by Ljungh et al. [JWC 15 (4), 2006, 175-80] showed that binding takes place rapidly, i.e. within 30 seconds. When measured after 2 hours, Cutimed Sorbact continuously bound more microorganisms.
Is Cutimed Sorbact effective in the treatment of MRSA?
Strains of MRSA (methicilin resistant Staphylococcus aureus) express cell surface hydrophobicity just as the non-resistant bacteria do and therefore also bind to Cutimed Sorbact. The same applies to VRE (vancomycin resistant Enterococcus).
Can bacteria or fungi develop resistance against Cutimed Sorbact?
The Sorbact method is based on hydrophobic interaction. This basic physical principle is vital for microorganisms, e.g. for intake of food, exchange of genetic information, or adherence to tissue cells in the infective process. Development of resistance against hydrophobic interaction would be self-destructive for microorganisms.
How is Cutimed Sorbact applied to the wound?
Cutimed Sorbact and Cutimed Sorbact gel must have direct contact with the wound bed. Superficial wounds should be dressed with swabs or absorbent dressing pads.
Deep or cavity wounds should be packed with round swabs, ribbon gauze or swabs (depending on the wound size) before covering with a dressing pad to ensure direct contact of the dressing to the wound.
Are there any recommendations of use for Cutimed Sorbact?
Moist wound conditions are essential to ensure the efficacy of Cutimed Sorbact and to avoid potential sticking to the wound. In dry or low exuding wounds it is recommended to use Cutimed Sorbact gel dressings.
No ointments or creams should be used in combination as fatty substances will interfere with the dressings' bacteria-binding properties.
How often do you have to change the dressing?
The frequency of dressing changes depends on the exudate level and the degree of wound contamination. It is recommended to change the dressing every 1 to 3 days. In wounds that show signs of clinical infection, a more frequent wound inspection is advisable. In these cases, an appropriate systemic treatment should be considered.
Can Cutimed Sorbact be cut to size?
It is not recommended to cut the dressings as small fibres might shed and remain in the wound.
How long should Cutimed Sorbact be used?
Until the wound is clean and there is no risk of further colonisation. When microbial balance is achieved it is recommended to change to other suitable wound dressings for the healing phase e.g. moist wound healing products.
Is Cutimed Sorbact compatible with secondary dressings e.g. foam dressings or alginates?
Cutimed Sorbact swabs and ribbon gauzes are very compatible with hydroactive dressings, e.g. to ensure a moist wound environment, as long as Cutimed Sorbact has direct contact with the wound bed and the secondary dressing does not contain any fatty substances (e.g. paraffin, ointments or creams).
Can Cutimed Sorbact be applied on top of another dressing?
There are no known contraindications for Cutimed Sorbact absorbent pads, swabs or ribbon gauzes.
To achieve an bacteria-binding effect in the wound, Cutimed Sorbact must have direct contact with the wound bed. Therefore it must be applied as the primary dressing and never as a secondary dressing.
Can Cutimed Sorbact be used while the patient is treated with systemic antibiotics?
Certainly, there is no interaction between systemic antibiotic therapy and local bacteria-binding treatment with Cutimed Sorbact.
