Medical textiles for advanced wound care dressings and drug delivery mechanisms

Abstract

It is a known fact that skin plays a crucial role as a protective barrier from the external environment and also prevents external noxious agents such as all type of microbes from getting inside the body. Hence it is crucial, that the skin remains intact so that the designated functions of skin are performed in an uncompromised manner. The body has higher chance of getting infected when newlinethe skin is damaged, due to any cause (mechanical injuries, ulcers, burns, neoplasm or surgical trauma). Whenever this happens the resources of body are wasted in fighting them all. The conventional olden method of managing the wounds were to try and take them from wet stage to dry stage. The conventional dressings were constructed in such a way that they were supposed to dry the wounds completely. This concept has changed in modern science of wet to moist dressings. With the advanced progress of technology, invention of new techniques and new materials, the old understanding has changed and also majorly accepted all around. New approach lays stress on need of moist wound conditions for better healing. These new generation dressings are engineered for handling specific wound conditions that suit the dynamic process of wound healing. Moist wound facilitates epithelialization of wound. Also water soluble essential substances that are vital for the healing of wound like the amino acids, sugar, and electrolytes, are available for new cells formation only in the wet and moist form of wound. However, in terms of moisture balance, the wound should be kept moist but not highly wet and flooded with exudates. High level of exudates built up lead to maceration of the wound and hampers the wound healing and wound closure. newline newline
