Case Series Summary

Background: Case series studies are an important element in

understanding the clinical use of dressings on a variety of wounds to

which they are normally exposed. In this study an adhesive foam

dressing with a demonstrated high in vitro MVTR and a high in vivo

fluid handling capacity was studied on a variety of wound types and

in a variety of clinical settings.

Methods: The wounds selected were low- to high-exuding, partial-

and full-thickness dermal wounds that were currently being treated

with a foam dressing and were expected to use the study foam

dressing for four weeks. Weekly dressing changes were

recommended if possible, but more frequent changes were not

restricted. A total of 24 patients were enrolled into the study.

Baseline Demographics

Facility: 29% Home Care, 33% Long-Term Care, 38%

Wound Clinic

Gender: 54% Female, 46% Male

Mean age = 68.2 (19-91) Years

Mean weight = 212.1 (102-596) lbs.

Wound Type: 50% Pressure, 17% Venous, 29% Surgical,

4% Trauma

Wound Location: 38% Sacrum/Coccyx/Buttock, 21% Foot/Heel,

17% Abdomen, 17% Lower Leg/Knee, 8% Other (Flank/Spine)

Wide range of wound age and pre-study foam use

Overall Dressing Assessments

72% of the 140 dressing applications were rated as having good or very good

Ease of Application

Of the 116 dressing changes, 76% were rated as having good or very good Ease

of Removal

73% rated the dressing as very comfortable or comfortable

66% rated the dressing as maintaining a moist wound environment

89% of dressing changes were due to routine care, 3% due to leakage, 3% due to

soiled dressing

Wear Time: Mean (SD) = 4.8 (2.4) days (n=115 dressing applications) with the

investigators stating that 51% of the dressings could have remained on longer, and

at the end of the study they indicated that for all 24 subjects, the dressing met their

wear time expectations



5

Baseline Wound Area and Change

Nine out of the 24 (38%) subjects had their wounds heal

during the study

Baseline wound area ranged from 0.29 cm2 to 111.6 cm2

with a mean of 10.92 cm2 (median 3.9 cm2); At last visit

the mean area was 6.4 cm2 (median 0.17 cm2) with a

mean area reduction of 70.8% (median 93.2%) and a

mean absolute area reduction of 4.5 cm2 (median 2.08

cm2). The last visit occurred between 5 and 35 days of the

first dressing application (mean of 22.4 days and median

23 days of test dressing use



6

Case Study 1

Patient History:

75 year-old female

Venous ulcer (right medial malleolus)

Wound duration: 12-13 weeks

Prior treatment included a silver/foam dressing (~4 weeks),** a foam

dressing (~2 weeks), †† and then gentle adhesive foam dressing

until study enrollment (about ~5 weeks). ‡‡ Two-layer compression

maintained throughout the pre-study and study period

Punch biopsy 4 weeks pre-study suggestive of stasis dermatitis

Case Study 1 Patient Outcome with Test Dressing*

Wound assessed healed after 4 weeks with use of the test

dressing* and continued compression therapy

Mild maceration at baseline but none after switching to the test

dressing*

Mild erythema at baseline and at week 2, decreasing to none at

week 3 and 4

Moderate exudate (serous) at baseline, decreasing to mild at

weeks 1, 2, & 3,with none present at week 4 (healed)

No adverse events reported during treatment period



9

Case Study 1 Summary

Results of this case study demonstrate utility of the test dressing* on

a longstanding venous ulcer undergoing compression therapy

After switching to the test dressing,* the wound healed rapidly within

4 weeks of treatment

The clinicians involved assessed that the test dressing was better

able to handle the amount of exudate produced by the wound and

thus promoted better healing than the prior dressings in use

Wear time for the test dressing* averaged 7 days with no

unscheduled dressing changes needed

Case Study 1 Photographs



11

Case Study 2

Patient History:

63 year-old female

Abdominal surgical wound with hypergranulation

tissue

Wound duration: > 3 months

Treated for >4 weeks in nursing home

Previous foam dressing†† changed daily due to

dressing edge lift



12




13


Wound improved significantly and was nearly closed after 4 weeks

with use of the test dressing*

Mild maceration at baseline but none after switching to the test

dressing*

Mild erythema at baseline and mild/no erythema with the test

dressing*

Exudate (serous) rated as mild at baseline and continuing throughout

the study. Exudate contained some liquefied necrotic tissue at week

one due to silver nitrate treatment of hypergranulation tissue




14


Results of this case study demonstrate utility of the test dressing* on slow healing

dehisced surgical wound with hypergranulation tissue

Clinicians found it difficult to keep the previous foam dressing†† on for more than

one day due to the challenging location and exudate present

After switching to the test dressing,* the wound improved rapidly within 4 weeks of

treatment

The clinicians involved assessed that the test dressing was better able to handle

the amount of exudate produced by the wound and thus promoted better healing

than the prior dressings in use

Wear time for the test dressing* averaged 5.6 days which included one non-

dressing related unscheduled dressing change



15




16

Case Study 3

Patient History:

19 year-old male

Stage III pressure ulcer on heel

Wound duration: > 1 year

Treated for >4 weeks in Home Care

Previous foam dressing §§ changed daily due to dressing

edge lift



17




18


Wound assessed healed after 2 weeks with use of the

test dressing*

No periwound maceration or erythema present at any

time during the study

Exudate (serosanguinous) rated as mild at baseline and

non present at week 2




19


Results of this case study demonstrate utility of the test

dressing* on a longstanding pressure ulcer

Clinicians found it difficult to keep the previous foam

dressing** on for more than one day due to the

challenging location of the wound

After switching to the test dressing,* the wound healed

rapidly within 4 weeks of treatment

Wear time for the test dressing* averaged 7 days with no

unscheduled dressing changes needed

21

Conclusions

Clinicians involved in this study found the test

dressing* to be easy to apply and remove, highly

conformable and comfortable for the patient, and

able to maintain a moist wound healing environment

Mean (SD) wear time was 4.8 (2.4) days and in all

cases met clinician wear time expectations

Results of this study corroborate in vitro MVTR and

in vivo fluid handling studies, showing this uniquely

designed dressing to have exceptional clinical

performance
