There is a need for cheap and efficacious wound dressings in developing countries. Banana leaves have been described as an excellent, inexpensive, easily available dressing material in tropical countries. As a natural product, banana leaves are heavily contaminated with various pathogens that must be removed before they can be used as wound dressings, but effective sterilization methods that do not affect the beneficial wound-dressing properties of banana leaves have not been described.
To study different sterilization methods and determine which can be used on banana leaves without affecting their beneficial wound-dressing properties.
We first compared the use of different decontamination techniques to reduce the natural microflora of the leaves and then tested the wound-dressing properties of the leaves in a mouse model of skin transplantation and in postsurgical patients in Uganda, Africa.
Steam sterilization proved to be the optimal sterilization technique. Banana leaves displayed wound-dressing properties that equaled those of petroleum jelly gauze dressings and were tested successfully in a clinical setting in postsurgical patients in Uganda, Africa.
We found banana leaves to be an excellent alternative wound dressing, combining the desirable properties of modern wound-dressing material with low cost.
发展中国家需要廉价且有效的伤口敷料。香蕉叶已被描述为热带国家极好的、廉价的、易于获得的敷料材料。由于香蕉叶是一种天然产物，因此其表面会附着大量的各种病原体，在将其用作伤口敷料之前必须将其清除，但尚未描述出既不会影响香蕉叶有益的伤口敷料性能，又有效的消毒方法。
研究不同的消毒方法，并确定哪些方法可以在不影响其有益的伤口敷料性能的情况下用于香蕉叶。
我们首先比较了不同的去污技术的使用，以减少叶子的天然菌群，然后在皮肤移植的小鼠模型和乌干达非洲的术后患者中测试了叶子的伤口敷料性能。
蒸汽消毒被证明是最佳的消毒技术。香蕉叶显示出与凡士林纱布敷料相当的伤口敷料性能，并在乌干达非洲的术后患者的临床环境中成功进行了测试。
我们发现香蕉叶是一种极好的替代伤口敷料，它结合了现代伤口敷料材料的理想特性和低成本。
