Wound Preparation

Preparing a foundation for wound healing

Effective preparation of the wound bed and surrounding skin includes proper cleansing and removal removal of harmful components that can impede healing. These factors include slough, hyperkeratotic skin, debris, and high levels of bacteria – including biofilm4-6

KerraPrep – Your partner in wound bed preparation

  • Soft, polyester-fiber pads with finger pouch are conformable and controllable
  • Gently removes non-viable tissue, hyperkeratotic skin, and debris
  • Increases patient tolerance and acceptance
  • Physically disrupts biofilm*7,8 and helps reduce wound bioburden9
  • Helps prepare the wound bed for efficient use of sharp KerraPrep (curette, scalpel, scissors)
  • Reduces the risk for cross contamination10

The Benefits

KerraPrep physically disrupts biofilm and helps reduce bioburden9

Pseudomonas aureginosa biofilms were grown for 24 h on membranes before placing onto 1cm^2 pieces of pig skin. Biofilms were left to grow for a further 24 h. Biofilm removal was assessed by attaching KerraPrep to a toothbrush simulator.

After treatment, biofilms were visualised with blue staining. Viable bacteria appear pink whereas nonviable bacteria and porcine cells appear blue.

Quantification using Image ProPlus software revealed significantly less viable biofilm after using KerraPrep™ compared to NA Gauze

KerraPrep reduces risk for cross contamination10

Bacterial lawns of Pseudomonas aeruginosa were prepared on fresh agar plates and incubated over night. Using clean nitrile gloves, gauze and KerraPrep were used to clean the agar plate then the gloved hand was pressed onto a fresh plate. The plate was incubated overnight and assessed for bacterial transfer.

Gauze allowed considerable bacteria to be transferred from the users glove to post cleansing. Dense bacteria presence is indicated by the brown hue.

KerraPrep allowed dramatically less bacterial transfer. The lack of brown hue shows reduced bacterial presence compared to gauze.
