In the treatment of non-healing wounds, the choice of a suitable wound dressing is an
important factor to support wound improvement. These wounds are often characterized
by bacterial infection, increased inflammation, varying exudate levels and the presence
of necrotic and sloughy tissue. In the present study, the efficacy and performance of a
novel bacteria-binding and absorbent wound dressing* was assessed. The new wound
dressing is indicated for contaminated, colonised or infected wounds with medium to
high exudate levels. A multi-centre study in Germany on 144 patients was conducted
and healthcare professionals rated the performance of the bacteria-binding, absorbent
wound dressing* in the treatment of different wounds. For an average of 12 days, all
wounds were treated with the dressing and the following parameters were measured: (1)
handling, (2) infection signs/infection control, (3) exudate and (4) odour levels as well as
improvement of wound healing (5).
In the time of treatment, the bacteria-binding wound dressing* reduced the signs of
infection in wounds from 59% to 35%. Most of the evaluated wounds showed reduced
exudate and odour levels and wound healing markedly improved. Moreover, since the
dressing does not release any active component many clinicians chose to use the
dressing for infection prevention.
In conclusion, this multi-centre study demonstrates that novel bacteria-binding and
absorbent wound dressing* combines effective topical infection control and management
with exudate management.

IMPACT OF FOAM DRESSINGS WITH SMALL PORES AND NARROW PORE
DISTRIBUTION ON THE UPTAKE OF HIGHLY VISCOUS EXUDATE

1 BSN medical GmbH (Hamburg, Germany).
Introduction and Aim: Foam products are known for good fluid handling capacities
often measured with SolA (salt solution). Application of SolA cannot predict how foam
products will behave in real conditions since the absence of proteins which tend to
increase viscosity over time and leading to encrustations in and around the foams.
This test aims on showing the impact of foam structure on the ability to handle highly
viscous fluid shown in artificial wound model.
Methods: Foam dressings were put on a plate (37°C), through a hole in the middle an
albumin/pectin test solution was fed into the products (size 10x10 cm, 5 mm foam) at
2ml/hr over approx. 16 hours. A box (MVTR) on top filled with silica gel catches the
evaporated amount of water. Determination of gravimetric difference of the dressings
and the MVTR box before and after measurement and substraction from the initial
amount gets the absorption, MVTR and residue in the system. After measurement
photos of foam were taken to examine the uptake of fluid in the foam.
Results: It was found that foams with small pores separate the solid content from the
water which leads to encrustations on the model’s wound surface. Exemplary
comparison of 4 foam dressings*.
Conclusion: Fluids with high solid content like exudate with cell debris, proteins and
blood hardeners get filtered by small pored dressings so that heavy parts would reside
on the patient’s wound surface.
