Wound contact layer’s micro pores size is even much smaller than the cell, 20m. It protects epithelial growth into the pore. It is a highly advanced technology that eventually leads patients feel no pain with much much less scar.
Biopsy, toxicity and clinical tests which conducted by “Seoul National University” and other major hospitals testified that the MEDIFOAM has much better quality effects than any other company’s wound care products existing in the world currently

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.
3. Price The price of the products, except MEDIFOAM, was investigated from “Yahoo Shopping” site. All of the price based on 10cmX10cm size product and divided from standard price, MEDIFOAM.

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.
Appendix 1
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 9.3751.930 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

Department of Surgery, College of Medicine,
Hallym University, Seoul, Korea
Backgrounds ; Foam dressings are nonlinting and absorbent. They vary in thickness and have a non-adherent 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 graph1) 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)/Wo density (g/cmⅩ 3)
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. ℃BIOPOL GLOBAL CO., LTD.
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.
5) Surface water absorbing rate in wound contact layer (sec)
