Biofilm management combined with broad antimicrobial effectiveness(1)

Acute and chronic wounds have a tendency to become infected, which compromises the normal healing process. This leads to a greater burden on the health systems, long-term disabilities and an overall reduction in the patients’ quality of life.

The wound infection continuum2) describes the different stages of how microbes impact a wound and consequently shows when antimicrobials are indicated and when not. This helps wound care practitioners to find the best strategy to prevent, diagnose and manage wound infections.

Get to know our unique therapy concept that covers all stages of the wound infection continuum: Prontosan® to prevent the formation of biofilm and decrease the bacterial burden3) to prevent wound infection4), and Askina® Calgitrol® to manage wound infection.

Prontosan® - Wound bed preparation taken seriously

Wound infections are caused by the deposit and profileration of microorganisms in the surgical site of a susceptible host. There are numerous ways microorganisms can enter the wound bed. The infection can result in sepsis when bacteria spreads into the blood stream. If not actively treated, a sepsis can progress to multi-organ failures with a potentially lethal outcome.

The main objective is to prevent infections rather than to treat them. Learn more about wound bed preparation.

Askina® Calgitrol® - Managing wound infection

The treatment of local infection is essential for the healing process. Silver Alginates react immediately and are highly efficient against a wide range of microorganisms. Our unique silver dressings play an important role in reducing the bacterial load.

Due to its specific and patented ionic silver alginate matrix, Askina® Calgitrol® provides a broad antimicrobial effectiveness.(1) In contact with wound exudate, the alginate matrix forms a soft gel allowing a sustained controlled release to the wound bed during use of the dressing.(5) Learn more about Askina® Calgitrol® silver dressings.

Case report: The use of Prontosan® in combination with Askina® Calgitrol®

An independent case series6)

The following case studies were carried out to evaluate the efficacy of a biofilm remover/cleanser in gel form - Prontosan® together with the use of an ionic releasing silver alginate - Askina® Calgitrol® Paste or Askina® Calgitrol® Thin - when used on infected wounds.

Treatment protocol

The following treatment protocol was followed for all wounds in the study:

  • Wounds were soaked for 15–20 minutes with Prontosan® gel or Prontosan® irrigation solution moistened gauze. Both the gel and the soaked gauze was kept in place by using cling film, gel was wiped away with saline gauze and soaked Prontosan gauze was used to wipe the wound
  • After wound cleansing, Calgitrol® Thin or Calgitrol® paste was applied depending on wound size and depth
  • The secondary dressing applied varied from non-adhesive foam to high-absorbent composite dressing depending on exudate levels

Results: Infection resolve time

All wounds showed a signi cant reduction in terms of clinical signs of infection within the first week of treatment. Some 50% of all wound infections were completely resolved by week 2. Eighty-one per cent of all wounds had no clinical signs of infection in less than 3 weeks. None of the patients were given any oral orintravenous antibiotics while on the study; all patients were only treated by using local antimicrobials. There was also a decrease in odour in all wounds.

Antimicrobial resistance and misuse of antibiotics

Antimicrobial resistance (AMR) develops when microbes adapt and build immunity against antimicrobial drugs such as antibiotics. Over- and misuse of antibiotics increase this problem and present a serious health threat, since infections with antibiotic-resistant bacteria are associated with longer hospital stays and higher death rates. Antimicrobial resistant infections currently cause at least 50,000 deaths across Europe each year.7) And estimates are that by 2050 antimicrobial resistance will account for 10 million deaths worldwide per year, leading to annual global costs of US$100 trillion.7)

AMR is a worldwide problem involving multiple sectors that is being addressed from different angles. The key strategy of this battle against the rise of antimicrobial resistance and healthcare-associated preventable infections is the adoption of local and national antimicrobial stewardship programs facilitating more prudent prescribing of antibiotics.  

Antimicrobial stewardship

Regarding wound management, it is the European Wound Management Association (EWMA) which has taken the lead in introducing a tailored stewardship concept to wound care practitioners. The aim of this  Antimicrobial Stewardship program, which B.  Braun is proud to sponsor, is to reduce the inappropriate use of antibiotics in wound care by promoting the use of non-antibiotic antimicrobials across all healthcare settings.8) One of these alternatives is Askina® Calgitrol®, which provides broad-spectrum antimicrobial activity for acute or chronic wounds with, or at risk of, a high level of bioburden or local infection.
