The concept of wound bed preparation can be implemented using the TIME paradigm. Chronic wounds are mostly characterised by prolonged inflammation and increased bioburden. Removal of wound biofilm and devitalised tissue, which is an ideal environment for bacterial growth, can help address the I in TIME. Wound cleansing aims to remove contaminants, debris, dressing remnants and superficial slough from the wound. Some wound cleansers contain surfactants, which reduce the surface tension of a liquid, enabling it to spread further over a surface. This article describes how these solutions can be used to debride the wound surface without damaging healthy cells.
伤口床准备的概念可以通过TIME模式来实施。慢性伤口的主要特征是炎症持续时间长和生物负荷增加。去除伤口生物膜和失活组织（这是细菌生长的理想环境）有助于解决TIME中的“炎症（Inflammation）”问题。伤口清洁旨在清除伤口中的污染物、碎屑、敷料残余物和浅表腐肉。一些伤口清洁剂含有表面活性剂，可降低液体的表面张力，使其能够在表面进一步扩散。本文介绍了如何使用这些溶液清创伤口表面而不损伤健康细胞。
