Tissue engineering-collagen sponge dressing for chronic wounds

Abstract

The high number of available wound dressing materials as well as the scientific reports about the topic indicate that the problem of an ideal wound dressing is to be solved. For the last half of century many scientific reports about collagen as wound covering have been published, the benefits of collagen application as a wound dressing being proved. The aim of the present study is to demonstrate the efficiency of the collagen sponge on healing full thickness skin wounds. The study population was divided into two groups: control and experimental. In the control group, the wounds were treated conventionally, using gauze swabs, in the experimental group such wounds being covered with collagen sponge, the results being compared. The wounds from the control group healed in 50 days, covering the wounds with collagen sponge in the case-group shortening the healing process to 27 days. Not only the healing time was shortened but also the quality of the wound repair by dressing the wounds with collagen sponge was enhanced.
