USABILITY, PATIENT SATISFACTION AND INTERFACE PRESSURE OF
A NEW COMPRESSION SYSTEM
Giovanni Mosti 1
1 Angiology Department; Clinica MD Barbantini (Lucca, Italy).
Aim: Multilayer, multicomponent bandages are considered the first choice treatment for
venous leg ulcer (VLU) treatment. Usability, patient satisfaction and interface pressure of
a new two components latex free compression device (TCS) were assessed.
Methods: In 20 patients affected by VLU, TCS was applied for 2 weeks with a weekly
interval change. The first component of the compression system, a short-stretch
bandage with padding properties, was applied with light stretch in a spiral way
overlapped by 50%. The second component, a short stretch cohesive bandage, was
applied with full stretch in a figure of eight way.
Results: TCS showed good results in the general assessment (slippage, rolling, loss of
sensitivity, feeling of tightness, heat, itching) rated nothing to low; technical assessment
(easy to use, ankle movement sufficient, thin without problems for shoes, comfortable)
rated excellent to good; quality of life rated as very good. The mean interface pressure
(IP) of TCS after bandage application was 62.5 mmHg in supine and 80 mmHg in
standing position. After 7 days, before TCS removal, the mean IP was 32 mmHg in
supine and 52 mmHg in standing position. The Static Stiffness Index was 18 after
bandage application and 20 after 7 days in the range of stiff bandages.
Conclusion: The new TCS showed to exert a very strong pressure with high stiffness
and to be, simultaneously, comfortable, well tolerated, thin enough to avoid problems
with the normal shoes. These characteristics suggest the new compression device could
be very effective in VLU treatment.

TOLERABILITY OF WOUND DRESSINGS WITH SILICONE OR POLYACRYLATE
GLUES (BORDER OR WOUND PAD) DEMONSTRATED BY A CLINICAL-
EXPERIMENTAL SKIN STRIPPING TEST

Germany).
Aim: The aim of the study was to investigate the tolerability of six foam wound dressings
with adherent border and adherent wound pad (with polyacrylate** or silicone glues*) on
healthy skin (impairment of the skin’s barrier function).
Method: On 15 volunteers the foam dressings were applied 5times (randomized, singleblind,
intra-individual comparison). The assessment for barrier damage was
demonstrated by Transepidermal Water Loss (TEWL), the removal of stratum corneum
measured by chromametry after staining, pain before and after removal as well as a
clinical evaluation of tolerability (erythema, dryness, fissures, papules, pustules, edema,
vesicles, weeping, other). A positive approval of an independent ethic committee was
available (feci code: 012/1966).
Results: The results are summarized in table 1 exemplary (after 5 repeated applications
vs untreated or stained). TEWL was statistically increased for the polyacrylate group** in
contrast to the silicone group* (border and wound pad). The removal of the stratum
corneum was higher in the acrylate group**. Furthermore the silicone group*
demonstrated a very good pain tolerance and general tolerability (eg erythema).
Conclusion: Silicone wound dressings* showed a less tendency to damage the skin
than wound dressings with polyacrylate glues**. Therefore the adequate indication of
each product group is important. Silicon dressings* are more suitable for sensitive
patients (eg with parchment skin, pain sensitive), polyacrylate wound dressings** for
special localizations with the need of high adherent properties like sacral pressure sores.
