- Brief Summary
Objective:
To evaluate the efficacy and safety of Prontosan® Wound Irrigation Solution in the treatment of hard-to-heal venous leg ulcers compared to wound irrigation with saline solution
Methodology:
Randomised, controlled multi-centre, prospective clinical trial
Planned number of subjects:
20 patients in experimental group (Prontosan® Wound Irrigation Solution) 8 patients in control group (wound irrigation with saline)
Products under investigation:
Prontosan® Wound Irrigation Solution
Study Duration:
3-4 weeks
- Detailed Description
Investigational product, dose and administration:
Prontosan® Wound Irrigation Solution (experimental group) and saline solution (control group) will be applied at inclusion and reapplied after dressing changes.
The treatment scheme is as follows:
1. Prontosan® Wound Irrigation Solution (experimental group):
* cleansing the wound bed at dressing change with Prontosan® Wound Irrigation Solution; a sterile gauze dressing impregnated with the Prontosan® solution will be placed on the immediate wound in the form of a moist compress and removed after approximately 15 minutes;
* placing the primary dressing (Profore® WCL): the dressing will be impregnated with Prontosan® Wound Irrigation Solution;
* fixing the dressing to the wound using multilayered elastic compression bandaging (Profore® bandaging system).
2. Saline (control group):
* cleansing the wound bed at dressing change with saline; a sterile gauze dressing impregnated with the saline will be placed on the wound in the form of a moist compress and removed after approx.15 minutes;
* placing the primary dressing (Profore® WCL): the dressing will be impregnated with saline;
* fixing the dressing to the wound using multilayered elastic compression bandaging (Profore® bandaging system).
Dressings will be changed and the treatment procedure will be repeated in the clinic 2x/weekly or more. The efficacy of the treatment procedure will be evaluated on the basis of a 2 week observation period.
Treatment efficacy assessment:
* Assessment of clinical signs and symptoms at entry to the study and after one and two weeks.
* Quantitative and qualitative microbiological analysis at entry to the study and after two weeks.
* Wound planimetry using PictZar® CDM at entry to the study and after two weeks.
Primary aim:
* clinical signs assessed by:
1. reduction of slough and necrotic tissue
2. control of exudate
3. presence of granulation tissue
* reduction of inflammatory signs (surrounding skin)
* reduction in wound size (assessed by wound planimetry)
* reduction of bacterial load (quantitative and qualitative microbiological
Secondary aim:
- tolerance and safety assessment:
1. adverse drug reaction
2. adverse events
3. early withdrawal from the study
