1. Methods:
A clinical evaluation was carried
out. Eight patients with NPWT (5
gauze, 2 foam based and 1
epicutane NPWT) and four non
NPWT patients were included
and treated with the viscous
silicone sealant. Clinical- and
patientcentered outcomes were
assessed.
Aim:
Achieving and maintaining a
perfect seal is essential for
effective NPWT. Sometimes
this can be a real challenge
due to the body area where the
wound is located. Especially
wounds near the anus, the
genital region or the forefoot
are hard to seal. Additional
wound care products such as
cohesive paste are often used
to achieve a proper sealing of
the dressing. The aim of this
work is to test the lately intro-
duced liquid soft silicone seal-
ant and to discuss other indi-
cations for this new product.

9. Results:
The soft silicone sealant is easy to use and quick to
apply. It proved to be positive in terms of achieving an
ideal exsudat- and airtight seal for NPWT. The wear
time of the NPWT dressings ranged from 7-9 days and
there was no leakage. The removal of the sealant was
easy and no skin stripping was seen. The patients did
not report any pain while the silicone was removed.

10. Conclusion:
This silicone sealant overcomes the challenge of sealing
NPWT. It helped to reduce the need for dressing changes
and this may be helpful to save money. Beside NPWT we
see further indications for this product. Used in stoma
treatment to secure and seal it ensured that liquid stool
is unable to damage the skin and to seal high output
lymphfistulas.
