Comparison Test – Explanation of each graph
1. Absorption Capacity (g/cm3)
To measure the water absorptive of sample, pre-weighed dry sample was immersed in distilled water
for 24h. After the bulk water was removed by placing the absorbent paper, the weight of wet sample
was measured. The procedure was repeated with 5 different pieces of same foam. Then, the water
absorptive was determined according to the following equation :
Water absorptive (g/cm3) = {(Ws – Wd) / Wd} X density (g/cm3)
where Ws = weight of water absorbed sample
Wd = weight of dry sample
2. MVTR (Moisture Vapor Transmission Rate, g/m2/day)
ASTM E96-95 (CaCl2 or Desiccant Method) was used to determine MVTR by measuring the rate of
change of mass in a CaCl2 filled test dish on which the dressing was mounted. The test dishes
(maximum of five) were placed on a platform within an incubator set at 37±0.5℃ and maintained at a
relative humidity of 85±2% using a water. Periodic weightings determine the rate of water vapor
movement through the specimen into the desiccant. MVTR was calculated at a given time interval by the
following method.
MVTR = {( m / Δt ) X 24} / A (g/m2/day)
where m = mass of water absorbing over the specified time interval (g)
Δt = time interval (h) and
A = the effective transfer area.

Ⅲ. Product Information
MEDIFOAM
MEDIFOAM is an advanced wound dressing made by highly absorbent polyurethane
which has very unique structure. It provides the best moisture wound healing
environment resulted from both excellent absorption capability and moisture
permeability for exudates. And it is never non-adherent on the wound surface.
The protection layer is made by PU film which has minimal micro pore structure.
This structure protects bacterial invasion and maintain the optimal MVTR and releases
the absorbed exudates properly.
The absorption layer is composed of PU foam which has higher absorption capability
as almost 1,000%. It makes to absorb and hold the exudates from wound surface.
MEDIFOAM absorption capability is far superior than other dressings.
Especially, It provides perfect moisture wound environment continuously by holding the
absorbed exudates.
The wound contact layer is PU membrane which supports to absorb the exudates
smoothly and it prevents adherence of dressing on wound surface.

THE EFFECTS OF MEDIFOAM(HYDROPHILIC POLYURETHANE FOAM)
DRESSING IN SPLIT THICKNESS SKIN DONOR SITE
By Young oh Park, M.D., Kyung won Min, M.D.
Department of Plastic and Reconstruction
Surgery, College of Medicine, Seoul
National University, Seoul, Korea
The purpose of our study is to evaluate the effects of occlusive wet dressing by using hydrophilic
polyurethane foam, MEDIFOAM ®, in the management of donor sites of split thickness skin graft.
The outer layer of MEDIFOAM ® is made of a polyurethane film, which is impermeable to water and
microorganisms. It provides moist wound environment and effective bacterial barrier. The middle layer
is polyurethane foam, absorption layer. It’s swelling ratio is 1020% and the layer contains wound
healing promoters. Inner layer is polyurethane film, which has micro pores whose size are below 20㎛.
It protects to epithelial growth into the pore.
Ⅳ. Appendix
We perform half side test to compare MEDIFOAM ® to Allevyn(the hydrocellular dressing materials).
We parted STSG donor site into Allevyn ® dressing site, and MEDIFOAM ® dressing site in random
fashion. This study was performed in Seoul National University Hospital from April 2001 till August
2001 with 32 patients, who need to skin graft.
We investigated about pain, comfort, healing, and time for complete healing.
The MEDIFOAM ® dressed site had less pain, more comfortable, easier handling and more rapid
wound healing. The average healing time of MEDIFOAM is 9.3751.930 days and AHD is 12.625
1.862 days(p<0.001)
So we conclude that occlusive dressing with MEDIFOAM ® is an effective dressing method in split
thickness skin graft donor site, and we expect that it is also effective dressing material in many other
wounds.

THE TREATMENT OF DONOR SITES WOUND
USING FOAM DRESSING MATERIAL
By Jong hyun Kim, M.D., Youb nam Koong, M.D.,
Dong kun Kim, M.D., Yoon kyu Park, M.D.
Department of Surgery, College of Medicine,
Hallym University, Seoul, Korea
Backgrounds ; Foam dressings are nonlinting and absorbent. They vary in thickness and have a nonadherent layer that provides nontraumatic removal. Foams creates a moist environment and provide thermal
insulation to the wound. General characteristics of dressings include ; nonadherent, may repel contaminants,
easy to apply and remove, absorb light to heavy amounts of exudates, and may be used under compression.
Foam dressings may be used as primary and secondary dressings for wounds with minimal moderate: or
heavy drainage : as a primary dressing to provide adsorption and insulation; or as a secondary dressing for
wounds with packing. They also may be used to absorb drainage around tubes. Foams may not be effective
for wounds with dry Escher. They may macerate peri-wound skin if they become saturated. The purpose of
this clinical study was to evaluate its efficacy as a donor-site dressing for thermally injured patients.
Ⅳ. Appendix
Methods ; We have analyzed 80 burned patients requiring split-skin graft. We covered one side of
each donor site with hydrophilic polyurethane foam dressing. Medifoam® (Treatment group), the other
half with Vaseline gauze (control group). All grafts were removed using a Zimmer dermatome set to
cut at a thickness 0.005-0.010 inches. After hemostasis had been obtained, each donor site was
covered with the polyurethane foam dressing and the Vaseline gauze. At 2 days postoperatively, the
dressing were removed (first opening) and then the donor sites was observed daily until epithlization
was complete, or until a complication developed that required discontinuance of the study. We
examined donor site about epithelization, discharge, infection, scar formation, color and pain.
Results ; Eighty patients had their donor sites heal without severe complication in a mean time (for
complete healing) of 9.7 days for polyurethane foam areas, and 14.5 days for fine mesh Vaseline
gauze dressings. In seven cases, superficial wound infection occurred in control group. Treatment
group had more clean wound surface because of absorption of discharge, no hematoma, no infection,
no pain. Treatment group were healed with evenly, homogenously, and hypopigmentation compared
with control group.
Conclusion ; Polyurethane foam dressing improved epidermal wound healing by providing a moist
environment for enhanced epidermal cell migration and shortened the donor site healing time.

Comparison Test
Comparison Test – Explanation of each graph
1) Fluid Handing Test (Water absorptivity (% or g/㎤))
- To measure the water absorption capability of sample, pre-weighed dry sample was immersed in distilled water for 24h.
After the bulk water was removed by placing the absorbent paper, the weight of wet sample was measured.
The procedure was repeated with 5 different pieces of same foam. Then, the water absorptivity was determined
according to the following equation:
Water absorptivity (%) = (WS - Wo) / Wo × 100
Water absorptivity (g/cm3) = (Ws - Wo)/WoⅩdensity (g/cm3)
Where Ws = weight of water absorbed sample
Wo = weight of dry sample
2) MVTR (Moisture Vapor Transmission Rate, g/㎡/day)
- A ASTM E96-95 method (CaCl2 or Desiccant Method ) was used to determine MVTR by measuring the rate of
change of mass in a CaCl2 filled test dish on which the dressing was mounted. The test dishes (maximum of five) were
placed on a platform within an incubator set at 37±0.5℃ and maintained at a relative humidity of 85±2% using a
water. Periodic weightings determine the rate of water vapor movement through the specimen into the desiccant.
MVTR was calculated at a given time interval by the following method.
MVTR = ( m / △t) · 24 / A (g/㎡/day)
Where m = mass of water absorbing over the specified time interval (g)
△t = time interval (h) and A = the effective transfer area.
- MVTR were determined according to the ASTM Method E96-90, Procedure D (Inverted Cup Method). Evaporation
of water through the test sample was monitored by measurement of loss of weight of the cup. The condition on the
incubator were approximately 35±0.5 ℃ and 50±5% RH.

3) Vertical wicking rate (minutes)
- The vertical wicking rate test measures the time taken for a colored test liquid from a reservoir to wick a vertical
distance of 5cm through a test strip of foam of specified size when the test is performed at 37℃.
4) Vertical wicking absorbent distance (cm)
- The vertical wicking absorbent distance test is carried out in conjunction with the vertical wicking rate test. Vertical
wicking absorbent distance measures the vertical distance that is wicked to vertical section of the same standard size
foam sample used in the vertical wicking rate test. Such a determination is generally made after the sample has been
allowed to vertically wick test fluid to equilibrium.
