Burn wounds pose significant challenges in medical treatment due to their devastating nature and resource-intensive requirements. Temporary coverage of burn wounds using synthetic or biological dressings allows for reepithelization before definitive skin grafting. Allogenic skin grafts have been widely used but come with drawbacks such as rejection and disease transmission. The use of amniotic membranes (AMs) offers a promising alternative for temporary coverage, as they possess biological properties that promote faster healing and improved scar quality. The various components of the amniotic membrane, including pluripotent stem cells, extracellular matrix proteins, and regenerative factors, contribute to cell growth, migration, and differentiation, as well as preservation of the original epithelial phenotype.
Reliable information on the treatment of burn wounds with AM is needed. The knowledge gained in this project may help to include this advantageous modern concept of biological dressings in clinical practice. The purpose of this study is to use human amniotic membranes from our in hospital laboratory, as an allogenic biological dressing after enzymatic debridement in superficial partial thickness, deep partial thickness or full thickness burn wounds.
We will include 30 patients in a randomized-controlled trial with each patient receiving the study intervention and the control intervention. Two 7 × 7 cm burn wound areas will be compared regarding percentage of skin graft take, healing time, healing percentage value and total healing time. Human amniotic membranes will be compared to allogenic skin grafts.
由于烧伤创面具有毁灭性的性质和资源密集型的需求,在医学治疗中带来了重大挑战。使用合成或生物敷料对烧伤创面进行临时覆盖可在进行确定性皮肤移植前实现再上皮化。同种异体皮肤移植已被广泛使用,但存在诸如排斥反应和疾病传播等缺点。羊膜(AM)的使用为临时覆盖提供了一种有前景的替代方法,因为它们具有促进更快愈合和改善瘢痕质量的生物学特性。羊膜的各种成分,包括多能干细胞、细胞外基质蛋白和再生因子,有助于细胞生长、迁移和分化,以及保持原始上皮表型。
需要有关用羊膜治疗烧伤创面的可靠信息。本项目中获得的知识可能有助于将这种有利的生物敷料现代概念纳入临床实践。本研究的目的是使用我们医院实验室的人羊膜,作为浅Ⅱ度、深Ⅱ度或全层烧伤创面酶清创后的同种异体生物敷料。
我们将在一项随机对照试验中纳入30名患者,每名患者接受研究干预和对照干预。将比较两个7×7cm烧伤创面区域的皮肤移植成活率、愈合时间、愈合百分比值和总愈合时间。将人羊膜与同种异体皮肤移植进行比较。
